ADA drinking fountain height: 36 inches low, 38 to 43 inches high
An accessible drinking fountain has its spout no higher than 36 inches (915 mm) above the floor, so that someone in a wheelchair can drink from it (2010 ADA Standards, 602.4). A fountain for standing people has its spout between 38 and 43 inches (965–1090 mm) (2010 ADA Standards, 602.7), and where drinking fountains are provided, the 2010 ADA Standards ask for both kinds (2010 ADA Standards, 211.2). These are the two heights, how many fountains of each kind, the knee clearance under the low one, the spout, the water flow and the controls, each with its section of the standard.
This is a summary. The official 2010 ADA Standards for Accessible Design are the reference.
Spout height: 36 inches low, 38 to 43 inches high
The 2010 ADA Standards measure a drinking fountain at the spout outlet, the point where the water comes out, from the finish floor or ground. On the fountain a wheelchair user drinks from, the outlet is 36 inches (915 mm) above the floor at most (2010 ADA Standards, 602.4). On the fountain for standing persons, it is 38 inches (965 mm) minimum and 43 inches (1090 mm) maximum (2010 ADA Standards, 602.7).
The two figures solve opposite problems. A spout low enough for someone seated means bending far down for someone standing, and a spout at a comfortable standing height is out of reach from a wheelchair. So the standard does not pick one height in between: where there are fountains, it asks for one of each (2010 ADA Standards, 211.2).
Section 602 sets no single “standard” fountain height and no minimum for the low spout. What it fixes is a ceiling of 36 inches for the wheelchair accessible unit and a band of 38 to 43 inches for the standing one. What keeps the low spout from going much lower is the room a wheelchair user’s knees need underneath, explained in the clearance section below (2010 ADA Standards, 602.2 and 306.3).
| Fountain | Spout outlet height | Section |
|---|---|---|
| Wheelchair accessible (low) | 36 inches (915 mm) maximum above the floor or ground | 2010 ADA Standards, 602.4 |
| For standing persons (high) | 38 to 43 inches (965–1090 mm) above the floor or ground | 2010 ADA Standards, 602.7 |
| For children, with a parallel approach | 30 inches (760 mm) maximum, and no more than 3 1/2 inches (90 mm) from the front edge of the unit, bumpers included | 2010 ADA Standards, 602.2, exception |
Two fountains, or one hi-lo unit
Section 211 says how many accessible fountains there have to be, and it applies where drinking fountains are provided: on an exterior site, on a floor, or within a secured area (2010 ADA Standards, 211.1). It does not make anyone install a fountain that was not planned; where none are planned, none are required, even where there are water coolers or bottle fillers (U.S. Access Board guide to drinking fountains).
Where there are fountains, the count starts at two: one that meets 602.1 through 602.6, the wheelchair accessible fountain, and one that meets 602.7, for standing persons (2010 ADA Standards, 211.2). The Access Board explains that this dual access is counted on each floor with fountains, on an exterior site and in each secured area, so a fountain on the second floor does not make up for a missing one on the first (U.S. Access Board guide to drinking fountains).
- One unit for both: a single fountain that meets 602.1 through 602.6 and 602.7 may replace the two separate ones (2010 ADA Standards, 211.2, exception). That is what the Access Board calls a combination high-low unit, or hi-lo unit (U.S. Access Board guide to drinking fountains).
- More than two: 50 percent of the fountains meet 602.1 through 602.6, and 50 percent meet 602.7 (2010 ADA Standards, 211.3). When half is not a whole number, it may be rounded up or down, as long as every fountain counted meets one of the two (2010 ADA Standards, 211.3, exception).
- Secured areas: spaces where entry is restricted or controlled, from a room opened with an access card to the holding areas of a jail (U.S. Access Board guide to drinking fountains). In detention or correctional facilities, fountains that only serve holding or housing cells not required to comply with 232 are exempt (2010 ADA Standards, 211.1, exception).
| Fountains provided | Wheelchair accessible (602.1–602.6) | For standing persons (602.7) |
|---|---|---|
| One planned | at least 2 in all, so 1, or one hi-lo unit that meets both (2010 ADA Standards, 211.2 and exception) | 1, or the same hi-lo unit (2010 ADA Standards, 211.2 and exception) |
| Two | 1 (2010 ADA Standards, 211.2) | 1 (2010 ADA Standards, 211.2) |
| Four | 2 (2010 ADA Standards, 211.3) | 2 (2010 ADA Standards, 211.3) |
| Five | 2 or 3 (2010 ADA Standards, 211.3, exception) | 3 or 2, so that all five comply (2010 ADA Standards, 211.3, exception) |
Water coolers and bottle fillers. Section 602 does not name them, and the Access Board guide is clear that, where a drinking fountain is provided, a water cooler, a bottle filler or a nearby sink cannot stand in for either the low or the high fountain, in new construction, additions or alterations. They can be added to compliant fountains or built into them. Fixed or built-in ones must meet the rules for operable parts: on an accessible route, with clear floor space for a forward or side approach, and controls within reach that work with one hand. Where only one fountain or one bowl of a hi-lo unit has a bottle filler, the Access Board advises putting it on the wheelchair accessible one (U.S. Access Board guide to drinking fountains).
Clear floor space and knee clearance under the low fountain
A wheelchair user drinks from the low fountain head-on, rolling in under it. So the standard asks for a clear floor or ground space positioned for a forward approach and centered on the unit, with knee and toe clearance underneath (2010 ADA Standards, 602.2). These are the sizes:
| Element | Requirement | Section |
|---|---|---|
| Clear floor space | 30 by 48 inches (760 × 1220 mm) minimum, for a forward approach, centered on the unit; it may include the knee and toe clearance | 2010 ADA Standards, 602.2, 305.3 and 305.4 |
| Floor of that space | no changes in level; slopes no steeper than 1:48 | 2010 ADA Standards, 305.2 |
| Approach | one full unobstructed side of the space adjoins an accessible route or another clear floor space | 2010 ADA Standards, 305.6 |
| Toe clearance | the space from the floor up to 9 inches (230 mm); at least 17 inches (430 mm) deep and 30 inches (760 mm) wide; it counts up to 25 inches (635 mm) deep | 2010 ADA Standards, 306.2 |
| Knee clearance | the space between 9 and 27 inches (230–685 mm) above the floor, at least 30 inches (760 mm) wide; at least 11 inches (280 mm) deep at 9 inches and 8 inches (205 mm) deep at 27 inches | 2010 ADA Standards, 306.3 |
| Fountain in an alcove | the alcove is at least 36 inches (915 mm) wide when it is more than 24 inches (610 mm) deep | 2010 ADA Standards, 305.7.1 |
Read together, the numbers describe the shape of a low fountain. At 27 inches above the floor there has to be at least 8 inches of clear depth under its front (2010 ADA Standards, 306.3.3), so the front of the bowl sits at 27 inches or higher, while the spout stays at 36 inches or lower (2010 ADA Standards, 602.4). The Access Board puts the depth in one figure: knee and toe space together reach at least 17 inches and at most 25 inches under the unit, measured from its leading edge, bumpers included (U.S. Access Board guide to drinking fountains).
Clearances are measured from the usable clear floor space, not necessarily from the bracket or pedestal that holds the fountain up (2010 ADA Standards, advisory 306.1). The same knee and toe rules apply under an accessible sink, in ADA sink height.
Where the spout sits and how the water flows
Height is not enough: the water also has to be where a seated person can reach it with their mouth, near the front of the unit and away from the wall. These rules are part of 602.1 through 602.6, so they apply to the wheelchair accessible fountain (2010 ADA Standards, 211.2):
| Element | Requirement | Section |
|---|---|---|
| Spout, from the vertical support | 15 inches (380 mm) minimum | 2010 ADA Standards, 602.5 |
| Spout, from the front edge | 5 inches (125 mm) maximum, bumpers included | 2010 ADA Standards, 602.5 |
| Height of the water stream | 4 inches (100 mm) minimum | 2010 ADA Standards, 602.6 |
| Angle, spout less than 3 inches (75 mm) from the front | 30 degrees maximum | 2010 ADA Standards, 602.6 |
| Angle, spout 3 to 5 inches (75–125 mm) from the front | 15 degrees maximum | 2010 ADA Standards, 602.6 |
The angle of the stream is measured horizontally, relative to the front face of the unit (2010 ADA Standards, 602.6). The 4-inch stream has a purpose the standard spells out: it lets someone hold a cup under the water, for a person who, because of a disability, could not otherwise use the fountain (2010 ADA Standards, advisory 602.6).
Buttons and levers: one hand, 5 pounds
The button, lever or bar that starts the water is an operable part, and it has to comply with section 309 (2010 ADA Standards, 602.3). The standard defines an operable part as a component used to activate, deactivate or adjust an element (2010 ADA Standards, 106.5).
- Space to use it: a clear floor or ground space complying with 305 (2010 ADA Standards, 309.2).
- Height: within the reach ranges of section 308 (2010 ADA Standards, 309.3). With an unobstructed reach, forward or to the side, that is 15 to 48 inches (380–1220 mm) above the floor (2010 ADA Standards, 308.2.1 and 308.3.1). Reaching forward over an obstruction, the high reach is 48 inches at most for a reach depth up to 20 inches (510 mm), and 44 inches (1120 mm) at most for a depth up to 25 inches (635 mm) (2010 ADA Standards, 308.2.2).
- Operation: with one hand, without tight grasping, pinching or twisting of the wrist, and with 5 pounds (22.2 N) of force at most (2010 ADA Standards, 309.4).
The fountain for standing persons needs compliant operable parts too, and it has to be on an accessible route (U.S. Access Board guide to drinking fountains). Where controls are designed mainly for children, an advisory table gives lower reach ranges: 20 to 36 inches for ages 3 and 4, 18 to 40 inches for ages 5 through 8, and 16 to 44 inches for ages 9 through 12 (2010 ADA Standards, advisory 308.1). Advisory notes explain the rules but are not enforceable requirements of their own (2010 ADA Standards, 28 CFR 36.406(b)).
Fountains in a corridor: protruding objects and cane users
A fountain mounted on a wall sticks out into the corridor, and for someone who is blind or has low vision, that can be something to walk into. Drinking fountains have to comply with section 307 on protruding objects (2010 ADA Standards, 602.1): an object with its leading edge more than 27 inches (685 mm) and not more than 80 inches (2030 mm) above the floor may protrude 4 inches (100 mm) at most into the circulation path (2010 ADA Standards, 307.2). The reason is the cane: an element in the range a cane can detect gives the person time to find it before their body touches it (2010 ADA Standards, advisory 307.2).
- The high fountain: with its leading edge above 27 inches, it has to be recessed in an alcove or otherwise treated so it does not protrude more than 4 inches, and the alcove has to fit the clear floor space of a wheelchair accessible unit (U.S. Access Board guide to drinking fountains).
- The low fountain: one whose knee clearance is exactly the 27-inch minimum has its leading edge at the limit a cane can detect, so it needs no treatment, and it can close off one side of a high unit. Benches and planters can also be used to recess a fountain (U.S. Access Board guide to drinking fountains).
- Side by side: the high unit may not block the forward approach to the low one, knee and toe space included. A cantilevered high unit with compliant knee and toe space may overlap that clear floor space, but the Access Board recommends placing it outside (U.S. Access Board guide to drinking fountains).
- The route: a protruding object may not reduce the clear width required for an accessible route (2010 ADA Standards, 307.5).
Drinking fountains for children
A fountain for children’s use may offer a parallel approach, where the wheelchair pulls up alongside the unit, instead of the forward approach with knee and toe clearance, if its spout is 30 inches (760 mm) high at most and no more than 3 1/2 inches (90 mm) from the front edge of the unit, bumpers included (2010 ADA Standards, 602.2, exception).
The Access Board adds two details: the exception is for fountains designed for children aged 12 and younger, and that parallel clear floor space does not have to be centered on the unit. The 2010 Standards do not say where fountains have to be designed for children; that is left to other building codes, good practice or the owner’s choice (U.S. Access Board guide to drinking fountains).
Existing buildings: alterations and the path of travel
In an existing building, an element that is altered has to comply with the requirements for it (2010 ADA Standards, 202.3). Drinking fountains also come up when other work is done. When an alteration affects an area containing a primary function, such as the dining area of a cafeteria or the customer service lobby of a bank, the path of travel to that area has to be made accessible to the maximum extent feasible, and the path of travel includes the restrooms, telephones and drinking fountains that serve it (2010 ADA Standards, 28 CFR 36.403(a)(1), (b) and (e)(3)). The same rule applies to state and local governments (2010 ADA Standards, 28 CFR 35.151(b)(4)).
That obligation has a limit: it is disproportionate when it costs more than 20 % of the alteration to the primary function area, and the cost of relocating an inaccessible drinking fountain counts toward that figure (2010 ADA Standards, 28 CFR 36.403(f)). When the full path cannot be done, the elements come in this order: an accessible entrance, an accessible route to the altered area, at least one accessible restroom for each sex or a single unisex restroom, accessible telephones, accessible drinking fountains, and then, when possible, parking, storage and alarms (2010 ADA Standards, 28 CFR 36.403(g)(2)).
Elements of a path of travel built or altered to the 1991 Standards do not have to be retrofitted to the changes of the 2010 Standards solely because a primary function area they serve is altered (2010 ADA Standards, 28 CFR 36.403(a)(2)). What the ADA asks of an existing business in general is in ADA compliance.
How to check a drinking fountain with a tape measure
If you manage a building, or you just want to know whether a fountain will work for you, these measurements cover most of section 602:
- Count. On that floor, outside or in that secured area, there is a low fountain and a high one, or one hi-lo unit that is both (2010 ADA Standards, 211.2).
- Low spout. From the floor to the spout outlet: 36 inches or less (2010 ADA Standards, 602.4).
- High spout. From the floor to the spout outlet: 38 to 43 inches (2010 ADA Standards, 602.7).
- Under the low unit. At 27 inches above the floor, at least 8 inches of clear depth under the front; the space at least 30 inches wide; and a clear 30-by-48-inch space in front, centered on the fountain (2010 ADA Standards, 602.2, 305.3 and 306.3).
- Spout position. No more than 5 inches back from the front edge, bumpers included, and at least 15 inches out from the wall or pedestal (2010 ADA Standards, 602.5).
- Controls. They work with one hand, without twisting the wrist, and with no more than 5 pounds of force (2010 ADA Standards, 309.4).
- Corridor. A unit whose front edge is more than 27 inches high sits in an alcove or is otherwise kept from sticking out more than 4 inches (2010 ADA Standards, 307.2).
A fountain can pass all seven and still be out of reach if the route to it has steps or a narrow door: the fountain is only as usable as the way to it.
Drinking fountains in Braillito Maps
Braillito Maps is a community map where each place answers ten questions: 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. Each answer is yes, no or no data, and the score of a place is the number of yes answers out of ten, with its color always shown next to the number.
A drinking fountain is not one of the ten. The app has no fountain question, and a fountain does not change a place’s score. The questions it sits closest to are the two that decide whether you can get to it at all: step-free entrance or ramp, and wide doorway. The ADA rules for alterations in an existing building put them in the same order, with the entrance and the route before the restroom and the fountain (2010 ADA Standards, 28 CFR 36.403(g)(2)).
The accessible restroom is a question of its own, and the restroom is what the ADA groups drinking fountains with on the path of travel (2010 ADA Standards, 28 CFR 36.403(e)(3)). When you add a place, mark only what you saw and leave what you do not know unmarked; if what a place says is wrong, it can be reported. Meet Braillito Maps.
Frequently asked questions
What is the ADA drinking fountain height?
On the wheelchair accessible fountain, the spout outlet is 36 inches (915 mm) above the floor at most (2010 ADA Standards, 602.4). On the fountain for standing persons, it is 38 to 43 inches (965–1090 mm) (2010 ADA Standards, 602.7).
Does the ADA require two drinking fountains?
Where drinking fountains are provided, there are at least two: one for wheelchair users and one for standing persons. A single hi-lo unit that meets both sets of rules may replace them (2010 ADA Standards, 211.2 and exception).
How much clearance does an ADA drinking fountain need?
A clear floor space of 30 by 48 inches (760 × 1220 mm) for a forward approach, centered on the unit, with knee and toe clearance underneath, 30 inches (760 mm) wide; at 27 inches above the floor the knee space is at least 8 inches (205 mm) deep (2010 ADA Standards, 602.2, 305.3 and 306).
Where does the spout go on an ADA drinking fountain?
No more than 5 inches (125 mm) from the front edge of the unit, bumpers included, and at least 15 inches (380 mm) from the vertical support, with a water stream at least 4 inches (100 mm) high (2010 ADA Standards, 602.5 and 602.6).
Can a bottle filler replace an ADA drinking fountain?
No. Where a drinking fountain is provided, a water cooler, bottle filler or nearby sink cannot substitute for the wheelchair accessible or the standing height fountain; fixed bottle fillers still have to meet the rules for operable parts (U.S. Access Board guide to drinking fountains).
What is the ADA drinking fountain height for children?
A fountain for children’s use may have a parallel approach instead of knee clearance if its spout is 30 inches (760 mm) high at most and no more than 3 1/2 inches (90 mm) from the front edge (2010 ADA Standards, 602.2, exception).
