ADA toilet height: 17 to 19 inches, and the rest of the toilet
Under the 2010 ADA Standards, an accessible toilet is 17 to 19 inches (430–485 mm) high, measured from the floor to the top of the seat (2010 ADA Standards, 604.4). Height is what most people look up, but section 604 of the Standards checks five more things around the same toilet: how far it sits from the side wall, the clear space next to it, the grab bars, the flush control and the toilet paper dispenser. These are the measurements, each with its section of the standard, and how to check them with a tape measure.
This is a summary. The official 2010 ADA Standards for Accessible Design are the reference.
Seat height: 17 to 19 inches, to the top of the seat
The seat of an accessible toilet is 17 inches (430 mm) minimum and 19 inches (485 mm) maximum above the finished floor, measured to the top of the seat, and it may not be sprung to return to a lifted position (2010 ADA Standards, 604.4). The measurement goes to the seat, not to the rim of the bowl, so it is taken with the seat installed and down.
The range is there for transfers: many wheelchair users move sideways from the chair onto the seat, and a seat at about the same height makes that move easier. The 2010 Standards do not use product names such as “comfort height” or “chair height”. What they check is the installed height, so to count as the accessible toilet, a toilet sold under one of those names still has to measure 17 to 19 inches to the top of the seat (2010 ADA Standards, 604.4).
Not every toilet in a restroom has to meet this rule. Where toilets are provided, at least one has to comply with section 604 (2010 ADA Standards, 213.3.2), and where there are toilet stalls, at least one wheelchair accessible stall, plus an ambulatory one in larger restrooms, has its own rules (2010 ADA Standards, 213.3.1), explained in the stalls section below. The measurements on this page are for that accessible toilet.
- In homes (residential dwelling units), the seat may be 15 to 19 inches (380–485 mm) high (2010 ADA Standards, 604.4, exception 2).
- In a single-occupant toilet room reached only through a private office, and not for common or public use, the seat height rule does not apply (2010 ADA Standards, 604.4, exception 1).
- For children, a toilet may follow the children’s rules instead (2010 ADA Standards, 604.1, exception): 11 to 17 inches (280–430 mm) to the top of the seat (2010 ADA Standards, 604.9.3).
| Age group | Seat height | Section |
|---|---|---|
| Ages 3 and 4 | 11 to 12 inches (280–305 mm) | 2010 ADA Standards, advisory 604.9 |
| Ages 5 through 8 | 12 to 15 inches (305–380 mm) | 2010 ADA Standards, advisory 604.9 |
| Ages 9 through 12 | 15 to 17 inches (380–430 mm) | 2010 ADA Standards, advisory 604.9 |
The age table is an advisory note: advisory notes explain or illustrate the requirements, but do not establish enforceable requirements of their own (2010 ADA Standards, 28 CFR 36.406(b)). The enforceable range for children is the 11 to 17 inches above.
Distance from the wall: the centerline
An accessible toilet sits with a wall or partition behind it and another on one side. Its centerline, the line through the middle of the bowl, is 16 inches (405 mm) minimum and 18 inches (455 mm) maximum from that side wall or partition. In an ambulatory accessible stall, the narrow stall with grab bars on both sides, it is 17 to 19 inches (430–485 mm) instead. The room or stall can be laid out for a left-hand or a right-hand approach (2010 ADA Standards, 604.2).
The side wall is where the long grab bar goes (2010 ADA Standards, 604.5), so the centerline rule is what keeps that bar within reach of someone seated on the toilet. A toilet pushed to the middle of a wide room can have the right height and still be impossible to use alone. For children’s toilets, the centerline is 12 to 18 inches (305–455 mm) from the side wall (2010 ADA Standards, 604.9.1).
The accessible toilet of Spain, Peru, Chile, Mexico and Argentina, from its height and the space beside it to the flush and the paper dispenser, compared country by country, is in the Spanish guide Inodoro accesible.
Clear floor space: 60 by 56 inches
Beside and in front of the toilet there is a clear space at least 60 inches (1525 mm) wide, measured from the side wall, and 56 inches (1420 mm) deep, measured from the rear wall (2010 ADA Standards, 604.3.1). It is the room a wheelchair needs to pull up next to the toilet or in front of it.
- What may overlap it: the toilet itself, its grab bars, dispensers, sanitary napkin disposal units, coat hooks, shelves, accessible routes, the clear floor space and clearances of other fixtures, and the turning space (2010 ADA Standards, 604.3.2).
- What may not: any other fixture or obstruction (2010 ADA Standards, 604.3.2). In a home, a sink may stand on the rear wall, at least 18 inches (455 mm) from the toilet centerline, only if the clearance is at least 66 inches (1675 mm) deep (2010 ADA Standards, 604.3.2, exception).
- The door: it may not swing into the clear space of any fixture, though it may swing into the turning space (2010 ADA Standards, 603.2.3). In a room for individual use, it may swing into it when a clear floor space of 30 by 48 inches (760 × 1220 mm) is left inside the room beyond the arc of the door (2010 ADA Standards, 603.2.3, exception 2, and 305.3). When the door is directly in front of the toilet, the toilet cannot overlap the maneuvering clearance the door needs inside the room (2010 ADA Standards, advisory 604.3.2).
- The room: it also needs a turning space, a 60-inch (1525 mm) circle or a T-shaped space within a 60-inch square (2010 ADA Standards, 603.2.1 and 304.3), measured as ADA turning space explains. The sink, the mirror and the rest of the room are in ADA bathroom requirements.
Flush control and toilet paper dispenser
| Element | Requirement | Section |
|---|---|---|
| Flush control | hand operated or automatic, on the open side of the toilet, the side of the clear floor space; the open-side rule does not apply in an ambulatory stall | 2010 ADA Standards, 604.6 |
| Hand-operated flush | usable with one hand, without tight grasping, pinching or twisting of the wrist, with 5 pounds (22.2 N) of force at most, and within the reach ranges: 15 to 48 inches (380–1220 mm) above the floor for an unobstructed forward or side reach | 2010 ADA Standards, 604.6, 309.3, 309.4, 308.2.1 and 308.3.1 |
| Paper dispenser, position | 7 to 9 inches (180–230 mm) in front of the toilet, measured to the centerline of the dispenser | 2010 ADA Standards, 604.7 |
| Paper dispenser, height | outlet 15 to 48 inches (380–1220 mm) above the floor, and not behind the grab bars | 2010 ADA Standards, 604.7 |
| Paper dispenser, type | operable with one hand without tight grasping, and allowing continuous paper flow: no dispensers that control delivery | 2010 ADA Standards, 604.7 and 309.4 |
| Children’s toilets | flush control 36 inches (915 mm) above the floor at most; paper outlet 14 to 19 inches (355–485 mm) high, with at least 1 1/2 inches (38 mm) of clearance below the grab bar | 2010 ADA Standards, 604.9.5 and 604.9.6 |
Two advisory notes help with the layout. When the dispenser is mounted above the side grab bar, its outlet still has to be 48 inches (1220 mm) high at most, and the top of the bar stays at 33 to 36 inches (840–915 mm) (2010 ADA Standards, advisory 604.7). And plumbing valves directly behind the seat can hurt or unbalance someone who leans back against them: the plumbing can go behind the wall or to the side of the toilet, or, if the local authority approves, the toilet can have a seat lid (2010 ADA Standards, advisory 604.6).
Grab bars at an ADA toilet
- Where: on the side wall closest to the toilet and on the rear wall (2010 ADA Standards, 604.5).
- Side wall bar: at least 42 inches (1065 mm) long, no more than 12 inches (305 mm) from the rear wall, and extending at least 54 inches (1370 mm) from the rear wall (2010 ADA Standards, 604.5.1).
- Rear wall bar: at least 36 inches (915 mm) long, extending at least 12 inches (305 mm) from the toilet centerline on one side and 24 inches (610 mm) on the other (2010 ADA Standards, 604.5.2).
- Height: horizontal, 33 to 36 inches (840–915 mm) above the floor to the top of the gripping surface; at children’s toilets, 18 to 27 inches (455–685 mm) (2010 ADA Standards, 609.4).
The diameter of the bars, their distance from the wall, their strength and the exceptions (a shorter, split or shifted rear bar, and homes or private offices where reinforced walls are enough) are in ADA grab bar requirements.
ADA toilet stalls: wheelchair and ambulatory
Where a restroom has toilet stalls, at least one is wheelchair accessible. An ambulatory accessible stall is added to it where there are six or more stalls, or where toilets and urinals together add up to six or more fixtures (2010 ADA Standards, 213.3.1); the urinal itself is in ADA urinal height. The two stalls are built for different people: the first for someone who transfers from a wheelchair, the second for someone who walks but needs a bar on each side to sit down and stand up.
| Element | Wheelchair accessible stall | Ambulatory accessible stall |
|---|---|---|
| Size | at least 60 inches (1525 mm) wide; 56 inches (1420 mm) deep with a wall-hung toilet, 59 inches (1500 mm) with a floor-mounted one (2010 ADA Standards, 604.8.1.1) | at least 60 inches (1525 mm) deep, and 35 to 37 inches (890–940 mm) wide (2010 ADA Standards, 604.8.2.1) |
| Toilet centerline | 16 to 18 inches (405–455 mm) from the side wall (2010 ADA Standards, 604.2) | 17 to 19 inches (430–485 mm) from the side partition (2010 ADA Standards, 604.2) |
| Grab bars | one on the side wall closest to the toilet and one on the rear wall (2010 ADA Standards, 604.8.1.5) | a side wall bar on both sides (2010 ADA Standards, 604.8.2.3) |
| Door | self-closing, with a pull on both sides near the latch, not swinging into the minimum stall area; in the front partition, within 4 inches (100 mm) of the side wall farthest from the toilet, or in that side wall, within 4 inches of the front partition (2010 ADA Standards, 604.8.1.2) | self-closing, with a pull on both sides near the latch, not swinging into the minimum stall area (2010 ADA Standards, 604.8.2.2) |
| Toe clearance | at least 9 inches (230 mm) high and 6 inches (150 mm) deep under the front partition and at least one side partition, unless the stall is larger than the sizes set in the exception (2010 ADA Standards, 604.8.1.4) | not among its requirements (2010 ADA Standards, 604.8.2) |
In both, when you approach the stall door from its latch side, there are at least 42 inches (1065 mm) between the door side of the stall and any obstruction (2010 ADA Standards, 604.8.1.2 and 604.8.2.2); the rest of the door follows the general door rules, in ADA door width. Coat hooks go within the reach ranges and shelves 40 to 48 inches (1015–1220 mm) above the floor (2010 ADA Standards, 604.8.3). A baby changing table may not take up the minimum space of a wheelchair stall, so a stall that also houses one has to be larger than the minimum (2010 ADA Standards, advisory 604.8.1.1).
How to check a toilet with a tape measure
If you run a café or a shop, or you just want to know whether a restroom will work for you, five measurements cover most of section 604:
- Seat height. From the floor to the top of the seat, with the seat down: 17 to 19 inches (2010 ADA Standards, 604.4).
- Centerline. From the side wall to the middle of the bowl: 16 to 18 inches (2010 ADA Standards, 604.2).
- Clear space. 60 inches out from the side wall and 56 inches out from the rear wall, with no sink or other fixture inside it (2010 ADA Standards, 604.3).
- Grab bars. The top of each bar 33 to 36 inches above the floor; the side bar at least 42 inches long, starting no more than 12 inches from the rear wall (2010 ADA Standards, 609.4 and 604.5.1).
- Flush and paper. The flush control on the open side; the dispenser 7 to 9 inches in front of the toilet, with its outlet between 15 and 48 inches high and not behind a grab bar (2010 ADA Standards, 604.6 and 604.7).
A toilet can pass all five and still be out of reach: the entrance, the restroom door and the turning space inside the room count too. For what the ADA asks of an existing business, see ADA compliance.
How Braillito Maps records an accessible toilet
Measuring is useful for one practical thing: knowing, before you go, whether the restroom at a place will work for you. Braillito Maps is a community map that answers ten questions about each place: step-free entrance or ramp, wide doorway, accessible restroom, accessible parking, tactile paving, braille signage, braille menu, audible signals, guide dogs welcome and a quiet environment.
The toilet goes under one of them, accessible restroom. Each question is answered yes or no, or stays without data until someone knows. The score of a place is the number of yes answers out of ten, and its color always appears next to the number, never on its own. The checklist does not ask for inches: it is a single yes-or-no question, so the five measurements above are a good way to decide what to answer when you add a place.
The restroom question sits next to the two that decide whether you can get to it at all: the step-free entrance or ramp, and the wide doorway. And if what a place says is wrong, it can be reported. Meet Braillito Maps.
