Bathroom stall dimensions, all in one place.

The quickest way to picture it is side by side. The ADA stall is almost twice as wide so a wheelchair can turn and pull up next to the toilet.

Most standard stalls are 36 inches wide and 60 inches deep. The plumbing code only asks for 30 inches wide, but 30-inch stalls feel tight and make the door hard to use. Many offices, restaurants and schools go 36 inches as the default, and some go 34 inches to fit one more stall in a row.

Depth

60 inches deep is the minimum with a floor-mounted toilet. A wall-hung toilet can work in 56 inches. If the door swings in, add room so the door clears the front of the toilet. Many designers plan 60 to 66 inches for inswing doors.

Room around the toilet

Keep at least 15 inches from the center of the toilet to the side wall or partition, and 21 inches of open floor in front of the toilet (IPC 405.3.1). Toilets in a row sit at least 30 inches apart, center to center.

The wheelchair stall is at least 60 inches wide. It is at least 59 inches deep with a floor-mounted toilet or 56 inches deep with a wall-hung toilet (ADA 604.8.1.1). The toilet sits 16 to 18 inches from the side wall, measured to its center.

Measure to the inside face, not the center

This is where most ADA stalls fail. The 60-inch width and the 56 or 59-inch depth are clear inside sizes: measured from the wall to the inside face of the partition or door. Many people just draw every ADA stall 60 inches deep without saying where the 60 is measured to. A wall-hung toilet only needs 56 inches, and a floor-mounted one 59, but only if those numbers are clear inside.

Shop drawings are not all made the same way. Some measure to the center of the pilaster or panel. On steel partitions, a stall drawn 60 inches to the center can end up about 59-1/2 inches clear inside, because you lose half the thickness of the pilaster. Draw a 59 to the center and you are short and fail inspection. Ask for the clear inside size on every ADA stall, or add half the pilaster thickness plus a little room.

• Wall-hung toilet: 56 inches deep minimum, clear.
• Floor-mounted toilet: 59 inches deep minimum, clear.
• Width: 60 inches minimum, clear, wall to inside face.

Don’t swing the door in on a 60-inch stall

A common plan shows a 60-inch ADA stall with the door swinging in. The door then sweeps through the space the wheelchair needs, and the stall fails. ADA says compartment doors can’t swing into the minimum stall area. Swing the door out, or make the stall bigger than the minimum so the door clears it.

Leave room beside the latch

Stall doors follow the ADA door rules in section 404, and those rules need open floor space beside the latch side of the door so a wheelchair user can reach the latch and pull the door open. On alcove layouts, where the ADA stall door is on the side and faces along the row, that space is often missing because the door sits tight to a wall or the next stall. When you come up to the latch side, ADA asks for at least 42 inches between the door side of the stall and anything in the way (ADA 604.8.1.2). Check this on the floor plan before the shop drawings are done. Some inspectors are flexible here, and many are not.

• Door: at least 32 inches clear. It sits no more than 4 inches from the side wall or partition farthest from the toilet, and it is self-closing with pulls on both sides.
• Side grab bar: 42 inches long minimum, starting no more than 12 inches from the back wall.
• Rear grab bar: 36 inches long minimum.
• Grab bar height: 33 to 36 inches to the top of the bar. Keep the 12 inches above the bar clear of dispensers and disposals.
• Latch and pulls: the latch throw, the part you slide to lock the door, and a door pull on both sides go between 34 and 48 inches high (ADA 404.2.7). Ambulatory stalls need the pulls on both sides too.
• Toe clearance: 9 inches high under the front and one side partition. You can skip the front one if the stall is more than 62 inches deep (wall-hung) or 65 inches deep (floor-mounted), and the side one if it is more than 66 inches wide.

What the code says

From the 2010 ADA Standards for Accessible Design:

604.8.1.1 Size. “Wheelchair accessible compartments shall be 60 inches (1525 mm) wide minimum measured perpendicular to the side wall, and 56 inches (1420 mm) deep minimum for wall hung water closets and 59 inches (1500 mm) deep minimum for floor mounted water closets measured perpendicular to the rear wall.”

604.8.1.2 Doors. “Toilet compartment doors, including door hardware, shall comply with 404 except that if the approach is to the latch side of the compartment door, clearance between the door side of the compartment and any obstruction shall be 42 inches (1065 mm) minimum. … The door shall be self-closing. A door pull complying with 404.2.7 shall be placed on both sides of the door near the latch. Toilet compartment doors shall not swing into the minimum required compartment area.”

ADA compliance depends on the whole room, not just the partitions. For hardware, grab bars and a full checklist, see our ADA bathroom partitions page.

If the toilet sits next to a partition panel instead of a wall, the side grab bar mounts to the panel. Order that panel with grab bar reinforcement, since the bar has to hold 250 pounds (ADA 609.8). A standard panel isn’t built for it.

Plans sometimes show an 18-inch vertical grab bar too. That one is not an ADA rule. It comes from ICC A117.1 and only applies where your city or state has adopted it, so check before you order. More in our ADA mounting heights guide.

Ambulatory stalls: what they are and who they’re for

An ambulatory stall is a narrow stall with a grab bar on each side. It is for people who can walk but need something to hold onto: someone using a cane, crutches or a walker, an older adult, or anyone who has trouble sitting down and standing up. The wheelchair stall is too wide for them, because the bars are out of reach on one side.

• Size: 35 to 37 inches wide and at least 60 inches deep. The narrow width puts both grab bars in reach.
• Door: closes on its own and can’t swing into the stall, so it usually swings out. The toilet sits 17 to 19 inches from the side wall.
• When you need one: when the room has six or more toilet stalls, or six or more toilets and urinals together. It is in addition to the wheelchair stall, not instead of it (ADA 213.3.1).

Wall-hung urinal screens are usually 18 to 24 inches deep and 42 to 48 inches tall, set about 12 inches off the floor. Floor-mounted screens run taller, often about 58 inches. Keep 15 inches from the urinal centerline to the screen, and 30 inches between urinal centers. An accessible urinal has its rim no higher than 17 inches (ADA 605.2).
