Commercial Bathroom Sinks

Which commercial sink fits your restroom

Pick by how many people use the sink at once and by what the wall or counter already gives you. A single wall mount sink suits a one-person restroom, a double or triple sink cast in one piece suits a restroom with a lunch or shift-change rush, and an undermount ramp sink suits a counter run you are building anyway.

List prices as of 7 Nov 2026, white stone resin or brushed steel. Gray and black stone resin cost more. Approved trade members get trade pricing on eligible products.

Pick by the room

• A one-person restroom in a café, shop or restaurant: a single wall mount sink. If it is the accessible restroom, make it a ramp sink.
• An office or hotel restroom with a rush at 9 a.m. or noon: a 60 or 72 inch double, or an 84 or 90 inch triple.
• Vanity cabinets already in the drawings: a 60 or 72 inch double vanity top, or undermount ramp sinks under your own counter.
• Brass or gold fixtures in the design: a stainless steel sink in brushed gold or rose gold.
• A gym, school or locker room where people share one long basin: our commercial trough sinks.
• A wall that fits none of our sizes: a custom width in Basin Studio.

Double and triple ramp sinks, drawn to scale

Our double and triple ramp sinks are one slab of stone resin, 22 inches deep and 5.3 inches thick, and every basin is 18.1 x 14.6 inches inside. Each basin floor slopes back to a concealed slot drain, so no drain cap shows and there is nothing on the deck to clean around. Going from 60 to 72 inches buys elbow room between two people (10.9 inches between basins instead of 6.9); going to 84 or 90 inches adds a third basin.

The 60 and 72 inch doubles also come as vanity tops that sit on a cabinet, with the same basins: the 60 inch double vanity top ($1,470 white) and the 72 inch double vanity top ($1,621 white). If you would rather have one long basin with a center drain, see our commercial trough sinks.

Custom sizes for your job

We make custom sinks for your job in Basin Studio, our online sink designer. You set the width, depth and height in inches, choose one, two or three bowls in a ramp, trough or oval shape, pick white, black or gray in matte or glossy, and watch the price update as you build. Custom sinks start at $784 and ship in 9 to 12 weeks within the United States.

Say the wall between the last stall partition and the corner is 80 inches. The 84 inch triple won't fit, and the 72 inch double leaves 8 inches of bare wall and one basin short. In Basin Studio you set the width to 78 inches, keep three ramp bowls and see the price before you order. After you order, we send a production drawing with every measurement, and nothing is cast until you approve it. Custom sinks are final sale, so the drawing is where you catch a wrong number.

Design a custom size

ADA restrooms: use a ramp sink

If the restroom has to meet the ADA, put a Badeloft ramp sink at the accessible station. Ramp sinks are the only Badeloft sinks we offer for ADA restrooms, because the drain sits at the back of the basin instead of the middle, which leaves more room for knees underneath.

The 2010 ADA Standards for Accessible Design ask that every accessible restroom with lavatories has at least one that meets Section 606, and it can't sit inside a toilet stall (Section 213.3.4). For that sink, Section 606 asks for:

• The front of the rim or counter at 34 inches or lower above the floor (606.3).
• A forward approach with knee and toe clearance underneath, and knee clearance at least 30 inches wide (606.2 and 306).
• Faucet controls that work with one hand, with no tight grasping, pinching or twisting of the wrist, at 5 pounds of force or less (606.4 and 309.4).
• Supply and drain pipes under the sink insulated or otherwise shielded so legs can't touch them, and no sharp or abrasive surfaces underneath (606.5).
• On a sink with more than one bowl, only one bowl has to provide the knee and toe clearance (606.2, exception 7).

Mounted with the rim at 34 inches, our 5.3 inch thick double and triple ramp sinks leave 28.7 inches of open wall below the slab. Your architect or inspector signs off the final layout, and state and local codes can ask for more than the federal standard. See every ramp sink we make, or read our guide to ADA bathroom requirements for the rest of the room.

Stone resin or vitreous china

A typical commercial lavatory is a white vitreous china bowl with faucet holes and an overflow. American Standard's Lucerne is a good example: a wall-hung, D-shaped vitreous china sink with faucet holes on 4 inch centers and a front overflow. It is the right sink for a back-of-house restroom or a per-fixture budget.

Stone resin is for the restroom your customers see, the one in a hotel lobby, a restaurant or a showroom. Ours is an acrylic and mineral composite, non-porous, cast in white, gray or black with a matte or glossy finish, and the double and triple sinks come out of the mold as one piece.

Our take: if nobody but staff will see the sink, buy vitreous china or stainless steel and spend the money elsewhere. If the restroom is part of how guests judge the place, price stone resin before you settle.

What to plan before you order

A wall-mounted sink needs its backing and its supply lines in place before the wall closes, so settle these while the studs are still open.

1. Count the sinks. The 2021 International Plumbing Code sets the minimum number of lavatories by how the building is used (Section 403.1 and Table 403.1), and the occupant count comes from the building code. Put the count on the plumbing plan before you order.
2. Put backing in the wall for every wall-mounted sink. Our catalog wall-mounted sinks ship with wall-mount brackets, and our guide to installing a wall mounted sink walks through the steps.
3. Choose the faucets with the sinks. Our double and triple ramp sinks and vanity tops have no faucet holes, so plan one wall-mounted faucet per basin and set each rough-in during framing. Catalog sinks vary by model, so check the product page.
4. Plan tempered water if customers use the restroom. The same code requires lavatories in public restrooms for customers, patrons and visitors to deliver tempered water through a temperature-limiting device that meets ASSE 1070 (Section 419.5).
5. Collect the paperwork early. Our catalog sink pages have spec sheets, mechanical drawings and CAD files. If your plans examiner asks for anything else, note it in your trade application.
6. Order to the schedule. Made-to-order sinks ship in 9 to 12 weeks, so order before the finish schedule needs them.

Picture a restaurant fit-out where the tile goes up before anyone picks the faucets. A deck faucet won't work on a sink with no holes, and moving the supply lines to the wall means cutting into finished tile.
