Introduction to Restroom Design






< >

Restroom Design

The key goals in designing a commercial restroom are accessibility, environmental considerations, ventilation, ample and comfortable lighting, signage that is clear and easy to understand, and safe and easily cleaned wall and floor finishes, toilet compartments, sinks and counters, fixtures, and accessories.






< >

Restroom Design Considerations

In a facility that emphasizes both sustainability and accessibility, architects and designers might consider the following before commencing design:

• How to lay out the restroom efficiently in order to comply with the accessibility standards of the Americans with Disabilities Act (ADA).

• What materials and products to use to make the room eco-friendly.

• How to select products when cost effectiveness is needed.

• Whether or not to automate the restroom.






< >

Restroom Design Considerations

While restroom design solutions should primarily respond to end users’ wants and needs, the design should also satisfy the building owner in both the look and overall cost, while satisfying the needs of the operations/maintenance personnel.

A design focussed on sustainability may result in lower operations and maintenance costs through the use of water-efficient faucets and lower-energy hand dryers. A facility that is designed efficiently to meet the standards of the ADA will often lead to a space that is both comfortable and empowering for all end users.

Finally, a well-designed washroom may reflect the building design and will elevate the user’s experience of the building.






< >

Restroom Sink Systems

One of the key areas that impacts the user experience, the look, and the sustainability of the washroom is the sink system. The sink system addresses the main issue of sustainability in a washroom, water use, and must be designed in such a way as to be accessible to all users. It is also often a central design feature of a washroom.

In the remainder of this course, we will look at some of the trends in sink systems that accommodate the goals of both sustainability and accessibility.






< >

Material, Style, and Component Options






< >

Sink/Counter Materials

Of all the components of the sink system, the one that has the most visual impact is the sink/counter material.

The most common sink/counter materials currently used are: solid surface, quartz, stainless steel, bio-based materials, and glass.






< >

Sink/Counter Materials: Solid Surface

Solid surface countertops comprise binding resins and mineral fillers. The resins typically used are either polyester or acrylic and amount to about 30% of the finished material. The mineral fillers may be either aluminum trihydrate (ATH) or polymerized granules.

Solid surface materials were designed to look and act like stone, but without its porosity. These materials are extremely hygienic and easily cleaned with soap and water. The watertight inseams are nonporous, and they are resistant to scratching, staining, impact damage, and heat.

These sinks offer pleasing aesthetics and design flexibility. They are an economic solution that fits into design budgets without compromising quality.






< >


Solid surface materials come in many colors and can be easily matched to any restroom color scheme.

Some solid surface materials are factory-molded and can be fabricated to specification. Fabricated sinks allow a degree of customization of size to fit any space. These countertops accommodate the installation of deck-mounted faucets and other components.

When specifying this type of sink, be sure to ask for adhesives and sealants that are “certified for low chemical emission,” as some of the sealants used in fabrications contain volatile organic compounds (VOCs). Using low-VOC sealants and adhesives means the sink may contribute to the LEED® 2009 Low-Emitting Materials – Adhesives and Sealants credit, or LEED v4 Low-Emitting Materials credit.






< >


Some fabricated solid surface materials may contain up to 13% pre-consumer recycled content. Pre-consumer content is scrap that is generated during the normal manufacturing process and is recycled back into its raw material state.

Recycled content contributes to LEED 2009 by value. Pre-consumer recycled content is worth 50% of its cost value. For instance, if a sink worth $100 contains 13% pre-consumer content, then its contribution would be $6.50 toward the total of all recycled content in the project. The LEED credit requires the project to use materials, including furniture and furnishings, with recycled content such that the sum of post-consumer recycled content plus ½ of the pre-consumer content constitutes at least 10% or 20%, based on cost, of the total value of the materials in the project.

In LEED v4, the credit that includes recycled content looks for products that meet a number of responsible extraction criteria, like bio-based material and FSC®-certified wood. To achieve a point, the total value of the products meeting these criteria must be 25% by cost of the total value of permanently installed building products in the project






< >


Molded solid surface sinks offer a lower-cost option when compared to fabricated sinks. They have less flexibility for customizing the sizes, and typically they have fewer color options available.

The solid surface material is still stain, chemical, scratch, and impact resistant, and typically these molded sinks include a stainless steel frame that supports the structure and ensures stability and strength. Molded sinks do not contain any adhesives or sealants.






< >

Sink/Counter Materials: Bio-Based

Bio-based solid surface materials are a fairly new alternative in which petroleum materials have been replaced with soy-based materials. They may comprise other bio-based products such as corn cobs or other agricultural or forestry materials in part or in whole. This offers a renewable option with no appreciable difference in the performance of the product.

Bio-based solid surface materials provide a natural look, with the type of bio-based material used influencing the overall aesthetic. The materials are easy to clean using common nonabrasive, nonchlorinated household cleansers and a soft cloth.

These sinks may contribute to the responsible extraction option of the LEED v4 Building Product Disclosure and Optimization ‒ Sourcing of Raw Materials credit for bio-based materials.






< >

Sink/Counter Materials: Quartz

Quartz surfacing material is similar to a solid surface in that it is a man-made material. Quartzcountertops are composed of about 90% ground quartz (a hard mineral) and 8‒10% resins, polymers, and pigments. However, some brands have much less than 90% ground quartz and still call their material quartz. Quartz is a hard granite-like material that is, in fact, harder and less porous than granite. This material is stain and crack resistant.

Quartz sinks can be made of various types of quartz which will provide different levels of durability and sheen. The more quartz in the mixture the more resistant the sink will be to scuffs and stains.






< >


Though quartz is a nonrenewable material, it is one of the most abundant minerals on earth; some quartz surfacing products have been certified by GREENGUARD as low-emitting materials and may contribute to LEED credits.

These preformed sinks can be ganged to provide more than one sink station and meet all accessibility requirements.






< >


Quartz surfacing comes in a variety of colors and has a glossy sheen. Quartz is very durable and has a superior aesthetic that lends itself well to luxury designs. Consider these quartz sink solutions for office buildings, restaurants, and hospitality projects.






< >

Sink/Counter Materials: Stainless Steel

Due to the popularity of the industrial aesthetic, stainless steel sinks are moving to the mainstream. They are easy to clean and durable. This material is ideal for healthcare applications as it is difficult for bacteria to adhere to.

Stainless steel is a highly recycled material and is completely recyclable at the end of its life. This material will contribute to LEED credits that address recycled content.

Stainless steel sinks are resistant to heat and are strong enough to resist denting over time.






< >

Sink/Counter Materials: Glass

Glass is a highly recycled and recyclable material. Durable and sanitary, this material can be formed into a wide variety of sink shapes. However, because of the high cost to produce glass sinks/counters, they are typically found in high-end office buildings and hospitality locations.

Glass countertops can be made of 100% recycled content or combine 100% recycled chip glass with concrete or resin to create the desired aesthetic. They are highly heat resistant, stain resistant, and very hygienic. They have low scratch resistance and are more difficult to repair than solid surface. They require frequent cleaning to maintain their aesthetic.






< >

Sink/Counter Styles: Solid Surface Curved Basin

Once the material has been chosen, the next decision is the style and form it will take.

We are all familiar with the traditional commercial sink with the flat slab of countertop and undermount sinks. Today there are a wide range of shapes and configurations to suit any design or need.

The unit shown here is a molded curved basin with sensor faucets. The curved design allows users to feel separated from each other while still providing a trough basin. Typical design options include two or three stations.






< >


The concealed cabinet frame is made of heavy-duty stainless steel with brushed stainless steel accents. The front panels ensure strength and stability, while providing fast and easy installation and maintenance access. These sinks can accommodate a number of stations and are designed to meet ADA requirements as shown at bottom right.

< >


The molded curved basin sink style shown here has integrated faucets with handwashing sensors and offers simple installation and easy maintenance access. All the components of the sink for this style—the shut-off valve, electronics, sensors, solenoids, and soap components—are kept secure, but accessible, in the top area.

This sink style is well suited to high-traffic areas such as stadiums, schools, office buildings, and airports because of vandal resistance and the time it takes to perform maintenance. Infrared sensors are recess-mounted in a stainless steel plate behind the aerator spray head, which keeps them out of the sight of users, eliminating much of the potential for damage. An optional gravity-fed, top-filled, manual soap dispenser is also available.

Less labor is required for maintenance or servicing as a single person can perform any need.

Sink/Counter Styles: Solid Surface Integrated Bowls

The design shown here has a flat lavatory deck with integrated sensor faucets and slightly pitched counter space between each of the two concave basins. This sink provides both functional and aesthetic advantages. The look of individual basins creates a more upscale feel and the sloped design between stations is designed to eliminate all standing water on the countertop. This design feature allows users to put down their personal items while they wash their hands. This solution works well in office buildings, healthcare facilities, public restrooms, and other environments.

The one-piece molded surface simplifies cleaning. The stainless steel cabinet below supports the structure and provides for fast and easy installation and maintenance access. Typical design options include one, two, or three stations.






< >

Sink/Counter Styles: Solid Surface Integrated Bowls

These sinks can easily be fabricated to meet knee clearance and sink thickness accessibility requirements. They are used in many commercial projects including education, hospitality, and healthcare.






< >

Sink/Counter Styles: Solid Surface Pedestal Basin

The unit shown here is a pedestal basin with integrated handwashing sensors and is ideal for high-traffic areas such as stadiums. This image shows a design that accommodates three users, but typical designs offer configurations for between two to four users.

The pedestal is made of steel with a satin finish and is supported by a galvanized steel mounting plate. The design is ADA-compliant. The continuous basin has a front access panel that allows for easy maintenance access and quick cleaning.

The installation is simplified because the sink arrives preplumbed with electronic controls.






< >

Sink/Counter Styles: Solid Surface Pedestal Basin

These sink types are designed to meet ADA accessibility requirements.






< >

Sink/Counter Styles: Sleek Design

These monolithic, sleek sink designs feature very angled edges and corners and are available with open or closed basins. The design is made up of one basin that can serve up to three faucet stations.

Shown here with integrated sensor faucets and soap dispensers, the sink also offers the option of adding integrated hand dryers.

Stylish, easy-to-clean surface decks are durable and resistant to staining, and are designed to specification for style, size, faucet, and soap dispenser. They are available in natural stone or solid surface in a wide variety of colors and custom configurations, including multiple stations.

Their design is particularly suited for upscale hospitality, contemporary restaurants, high-end retail, and executive office suites.






< >

Sink/Counter Styles: Sleek Design

These sink types are designed to meet ADA accessibility requirements.






< >

Sink/Counter Styles: Stainless Steel

Stainless steel handwashing sinks come preplumbed and preassembled with options for integrated sensor faucets. They are typically made of 14-gauge, type 304 stainless steel. They should contain sound softening panels internally, in order to deaden noise when located in an environment where many of these sinks will be running simultaneously.

The angled front corners enhance ease of use and protect users from sharp edges. The outer rim of the sink is raised to help prevent splashing and dripping on the floor, which is ideal for healthcare environments. The front access panels easily lift out for easy access when maintenance is needed. They are ADA-compliant and well-suited for healthcare, hospitals, food service, restaurants, and education applications.






< >

Sink/Counter Styles: Stainless Steel Surgical Scrub Sinks

The sink shown here is similar in design to the one on the previous slide, with the same features: preplumbed, preassembled, and built with angled front corners. The angles on the outer rim prevent splashing and spilling.

Unique to this sink is the location of the faucet sensors. Note they are located on the front panel of the sink, which makes them the perfect solution for any medical professionals who need to do an extended wash. Also available is a knee-activated soap dispenser for ease of use during the washing process. This sink style is not accessible, but it is a sustainable option given the recyclability of stainless steel and the water-efficientsensor faucets.






< >

Components for Handwashing

Handwashing is defined as the pattern of actions that we use to clean our hands: wetting, soaping, rinsing, and drying.

Although the actions to clean our hands remain the same, new innovations in sink and component design contribute to sustainability and accessibility.






< >

Components: Soap Options

Soap dispensers offer a number of options. They can be wall-mounted adjacent to the sink, or deck-mounted with electronic sensor-activated ability or be manual operation.

The sensor-activated dispensers are more hygienic as they don’t require touch to operate. These dispensers can be located on the deck adjacent to the basin, which also makes them an excellent choice when considering accessibility.

The trend in the industry is to use foam rather than liquid soap as it feels nicer and takes less time to rinse off.






< >

Components: High-Efficiency Faucets

Faucet choice will control a good deal of the water use in a washroom. Faucets can be specified as manual or electronic. Electronic faucets have several advantages: they are ADA compliant, vandal resistant, and more hygienic and water efficient than manual faucets. Like the electronic soap dispenser, the electronic faucet is a hands-free product and water use is controlled.

The CDC recommends washing for at least 20 seconds, which is about the amount of time it will take you to sing “Happy Birthday” twice to yourself.

This does not mean that the faucet should continually run for this time. Electronic sensors will note that the hands have been removed from the rinse area, while the washing is being done, and will turn the faucet off. This time-out feature saves both water and power.






< >


Faucets account for more than 1 trillion gallons of water use per year across the U.S. “Time-out” settings or “cycle time” for electronic faucets reduces overall water consumption. The average time a faucet is on, per user, is about 10 seconds. This comprises 2‒3 seconds to wet hands plus 6‒7 seconds to rinse. By using a 10-second time-out at 1.5 gallons per minute (gpm), the electronic faucet will deliver the EPA standard of 0.25 gallons per cycle (gpc).

For LEED calculations, the U.S. Green Building Council mandates a default 12-second duration of flow, which represents the total of all run times during the handwashing process. The 12-second default must be used, regardless of the faucet’s cycle time, which might be repeated during the process.

For example: a 12-second time-out (min.) using 0.5 gpm will result in a 60% reduction over the baseline amount. • Installed flow rate = Flow rate (gpm) x Duration (sec per cycle) / 60 sec• A faucet that has a 0.5 gpm flow rate will result in a calculation of: 0.5 gpm x (12 sec / 60) = 0.1 gpc

The study “Lavatory Water Consumption” conducted at Texas A&M University compared manual faucets to electronic faucets. The study consisted of three phases:

Tune-Up PhaseExisting manual faucets were tested after having been regulated to 1.0 gpmflow rates. Data was collected for two weeks in all restrooms to establish a baseline.

Study: Woods, Dr. Paul. “Lavatory Water Consumption.” Construction Science, Texas A&M University.






< >


Low-Consumption Phase Low-consumption, 0.5 gpm aerators were installed on the manual faucets and lavatory flows were remeasured. Again, data was collected for two weeks in all restrooms. Not surprisingly, a 50% savings going from 1.0 to 0.5 gpm was noted.

Automatic Phase Installation of sensor-operated faucets with 0.5 gpm aerators took place and lavatory flows were remeasured. Another set of data was collected for two weeks in all restrooms. During this final phase, a 39% savings with the automatic faucets was noted over the low-consumption phase. Study: Woods, Dr. Paul. “Lavatory Water Consumption.” Construction Science, Texas A&M University.






< >

Components: Hand-Drying Options

There are many types of hand-drying options, from paper towels to high-efficiency dryers.

The purpose is to remove the water from the end users’ hands before leaving the restroom.






< >

Components: Hand Dryers – High-Efficiency Options

Traditional hand dryers have taken about 35‒45 seconds to dry hands. As it takes only about 10 seconds to dry your hands with paper towels, hand dryers have not been a popular option and have been installed in only 10% of restrooms.

New high-speed electronic hand dryers are now changing people’s perceptions. These dryers can dry hands in 10‒15 seconds, matching the time taken when using paper towels.

The new dryers are more efficient, saving 80% of the energy expended by the traditional hand dryers and saving 100% of the cost of paper towels, while requiring less maintenance time for cleaning up paper waste.






< >

Components: Hand Dryers ‒ More Ways to Conserve

The three case studies below show how much lower operational costs are (90‒95% savings) for high-efficiency hand dryers over paper towel dispensers.

< >

Components: Hand Dryers – Deck-Mounted

There are definite benefits to having all three components—soap, water, and hand dryer—next to each other within reach of the hand washer. There is no need to move about to find the soap, and no dripping water on the floor on the way to the dryer.






< >

Components: Hand Dryers – Deck-Mounted System

Deck-mounted hand dryers are available from a number of manufacturers. These units sit on the vanity deck next to the soap dispenser and faucet. The deck location saves time for the user, and eliminates the messy water trail, making for a cleaner and safer restroom. The deck location also supports ease of use for those with different abilities.






< >

Components: Hand Dryers – Deck-Mounted System

A further innovation puts a high-speed hand dryer system on the deck of a fabricated solid surface sink that has been designed to capture the high volume of air generated from the hand dryer and prevent water or soap from exiting the sink area.

These deck-mounted systems have an adjustable sound suppression air delivery system so they are 50% quieter than comparable dryers and have an energy savings of 80% (GreenSpec listed). They are easy to install and virtually service free. With an optional HEPA air filter, the air that comes out of the hand dryer is actually cleaner than the air going into it.






< >

Components: The Integrated Difference

There is an aesthetic benefit to having all four restroom sink components—soap dispenser, faucet, hand dryer, and basin—match and sit together on the counter deck. It creates a cleaner looking design. Having sleek, state-of-the-art equipment, all touch-free and high-efficiency, results in a high-class experience. Having the components at arms’ length stops water puddles on the counter or drips of water on the restroom floor, so there is improved restroom cleanliness. Because all the units are touch-free, hygiene is promoted.

An integrated unit is supplied as a full unit so that the initial installation is simplified. Only one set of installers is required to complete the installation process.






< >

ADA Criteria for Planning






< >

Accessibility History

Since ANSI published codes and standards in 1961, there has been an increased focus on accessibility for all persons, especially in commercial restrooms. The Rehabilitation Act (Section 504) of 1973 guaranteed certain rights to people with disabilities. Congress passed the Americans with Disabilities Act (ADA) in 1990 and in 2010, ANSI revised its standards to include the ADA Standards for Accessible Design.

Today, all plans for renovations, remodeling projects, alterations, and new construction must fully comply with the 2010 ADA Standards as well as all applicable building code requirements.






< >

ADA Lavatory/Sink/Counter Requirements

Wheelchair accessible lavatories, sinks, and counters are the trickiest elements to be specified in a restroom.

All specified basins, sinks, or counters must be installed so that the lip is at 34″ (865 mm) in order to comply. As the knee clearance must be 27″ (685 mm) above the finished floor, the thickness of the basin, sink, or counter cannot be more than 7″ (178 mm).






< >

ADA Lavatory/Sink/Counter Checklist

Lavatory/Sink/Counter Checklist

Top front edge 34″ (865 mm) max.

Depth 17″‒25″ (430 mm)

Clearance from bottom of apron to finished floor 29″ (760 mm x 1220 mm) min.

Clear floor space W 30″‒48″ (735 mm)

Clear floor space under sink 17″‒19″ (430 mm - 485 mm)

Knee clearance height 27″ (685 mm) min.

Toe clearance height 9″ (230 mm) min. provided for full depth of sink

Plumbing Insulated or otherwise configured to protect againstcontact; no sharp edges or rough surfaces






< >

ADA Accessory Mounting Height Requirements

Mounting heights for restroom accessories can be no more than 48″ (1220 mm) above the floor. These accessories include soap and paper towel dispensers, hand dryers, hooks, and waste dispensers.

In the event that an accessory is mounted over a counter or another obstruction, it decreases the maximum height the accessory can be mounted. For instance, a counter or obstruction that is 20″ (508 mm) deep maintains the 48″ (1220 mm) height, but in the case where the counter or obstruction increases above 20″ (508 mm) to a maximum of 25″ (635 mm), the highest the accessory can be mounted is 44″ (1117 mm).

The operable portions of any accessory must be mounted no lower than 15″ (380 mm) above the floor.

< >

ADA Lavatory/Sink and Accessory Approach Clearance

The minimum clearance for a wheelchair user’s approach to a lavatory or sink counter is 30″ by 48″ (760 mm by 1220 mm). The same amount of space is required for the approach to any accessory.

Please remember the exam password ACCESSORY.You will be required to enter it in order to proceed with the online examination.






< >

Accessible Operation

All restroom accessories and faucets must be operable by one hand, without tight grasping, pinching, or twisting of the wrist. The amount of force to operate must not exceed 5 pounds of force (22.2 N) (lbf).

Faucets may be automated or hand-operated. Hand-operated and self-closing metered faucets are acceptable if they remain open (running) for 10 seconds at a minimum in order to deliver a maximum of 0.20 gpc.






< >

Specification Considerations






< >

Specifying a Sink System

To specify a sink/counter or a new integrated sink system, specifiers need to include the items that are important to the project.

When writing the specification, consider and include: the need for aesthetics and the amount of traffic and potential for damage when selecting finishes; the configuration, sizes, and numbers that are appropriate for the project; the importance of installation methods and ongoing maintenance issues; the type and capacities of all components; and sustainability and accessibility.

It is important that the specification be neither too broad, which will invite a large range of pricing options, nor too detailed, which will reduce the potential pricing options.






< >

Specification of Sink/Counter

To specify a sink that is both sustainable and accessible, the following need to be included:

• Look for materials that contain either bio-based or recycled content.

• Look for low-VOC options.

• Verify energy use of any electronic components.

• Counter/deck material should be stain, scratch, and impact resistant.

• The handwashing basin(s) should be ergonomic and accessible.

• Point of use sensor operations (if applicable) should be identified for faucets, soap dispensers, and hand dryers.






< >

Specification of Faucets

In addition to the overall sink, when specifying, consider the following requirements for sensor faucets:

• Ensure faucet meets or exceeds local low flow code requirements.

• Demonstrate interchangeability of components to simplify orders, upgrades, repairs, and maintenance.

• Offer multiple power-harvesting options to suit the environment’s unique needs.

• Provide multi-laminar spray—full-stream aerated or full-stream laminar—with adjustable flow rates as an option.

• Include a line purge function to eliminate the stagnant water that can lead to bacterial growth.

Course Summary

Thoughtfully designed sink systems are easy to install and maintain, and perfect for high-traffic environments. ADA-compliant, hygienic, stylish, and impact-resistant sink systems are perfect for schools, airports, healthcare facilities, officebuildings, and more. They are available in a variety of designs and configurations to suit project goals.

They can be made of fabricated or molded solid surface materials, natural stone, or quartz. There are systems made from bio-based materials, durable enough for commercial applications. Stainless steel, hands-free scrub, and handwashing sink systems are ideal for environments where hygiene is critical, such as hospitals and restaurant kitchens.

Systems combine soap dispensers, sensor-activated faucets, hand dryers, and sink basins. They are designed to work together as one, touch-free, hygienic, highly-efficient system that saves water, reduces energy consumption, and eliminates the need for paper towels.

Systems will comply with the 2010 ADA Standards and applicable building code requirements, and will help achieve sustainability goals. Accessibility and sustainability goals should be clearly addressed in the specifications.
