ADA showers: when the law applies and what it requires

Who has to follow the ADA shower rules

The Americans with Disabilities Act covers state and local governments (Title II) and businesses open to the public (Title III). When those entities build new facilities or alter existing bathrooms, showers they provide must meet the 2010 Standards, which the Department of Justice publishes on ADA.gov. Typical examples:

• Hotels, motels and short-term lodging with guest rooms that have mobility features
• Hospitals, nursing homes and outpatient clinics
• Fitness centers, pools, locker rooms and campgrounds
• College dorms, shelters and group homes
• Public employers' locker rooms and government buildings

Not covered: a house used only as a residence. The DOJ's Title III manual notes that a home office open to clients is covered, but the rest of the house is not. Owner-occupied inns with five or fewer rental rooms are also exempt.

Your state or city building code adds its own layer. Most U.S. jurisdictions adopt the International Building Code, which points to the ICC A117.1 accessibility standard. Where the code and the ADA differ, design to whichever is stricter, and confirm with your local building department.

The three compliant shower types

All dimensions below come from sections 608, 609 and 610 of the U.S. Access Board's text of the 2010 Standards. All sizes are measured clear, inside the finished walls.

Feature	Transfer type	Roll-in (standard)	Roll-in (alternate)
Interior, clear	Exactly 36 x 36 in	30 x 60 in min	36 x 60 in min
Entry width	36 in min	60 in min	36 in min, at one end
Threshold	1/2 in max with a beveled, rounded or vertical edge; up to 2 in where an existing slab can't be cut	1/2 in max	1/2 in max
Seat	Required (folding or fixed)	Optional; folding if installed	Optional; folding if installed
Best for	Users who slide from a chair to a seat	Users who stay in a shower chair	Narrow rooms where a long open face won't fit

Details inspectors check

• Grab bars: horizontal, 33 to 36 inches to the top of the gripping surface, strong enough for 250 pounds of force at any point. In transfer showers they run across the control wall and along the back wall to 18 inches from the control wall.
• Seats: seat top between 17 and 19 inches off the finished bathroom floor, reaching to within 3 inches of the opening.
• Controls: in a transfer shower, on the side wall across from the seat, between 38 and 48 inches high and no more than 15 inches from the seat centerline toward the opening. In roll-ins, mounted over the grab bar, 48 inches maximum.
• Spray unit: a hand shower on a hose of at least 59 inches that doubles as a fixed head, with a non-positive shut-off. A vertical slide bar must not block grab bars.
• Water temperature: 120°F maximum at the spray unit.
• Enclosures: doors or curtains must leave the controls reachable and the path to the seat clear.

Hotels and other transient lodging have added rules on how many rooms need roll-in showers and require folding seats in those roll-ins. An architect should run those counts for any lodging project.

"ADA compliant" vs. "accessible" at home

Product listings use the ADA label loosely. A shower base marked "ADA" may meet the size and threshold rules, but compliance is about the finished room: the clear floor space outside the shower, where the seat and controls land, and whether the walls can hold a grab bar. A box from a warehouse cannot be compliant on its own.

In a private home, you're free to pick the features that fit the person. A 60-inch curbless base without the full ADA control layout can be a better fit for a caregiver, for example. Use "accessible" or "barrier-free" for that kind of shower, and save "ADA compliant" for work that has been designed and inspected to the standard.

Even the Standards bend for residential dwelling units they cover: grab bars, and seats in transfer showers, can be omitted when the walls have backing that allows adding them later.

Multifamily housing and the Fair Housing Act

Apartments and condos follow a separate law. The Fair Housing Act's design rules cover buildings of four units or more that were first occupied after March 13, 1991. Covered units need usable bathrooms and reinforced walls for grab bars, but not full ADA roll-ins. The Justice Department's Fair Housing Act page summarizes enforcement. Leasing offices and other public areas in the same complex can still fall under the ADA.

Paying for an accessible shower

Businesses removing barriers may qualify for federal tax help: the Disabled Access Credit (IRS Form 8826) for small businesses, and a barrier removal deduction of up to $15,000 a year for businesses of any size, as ADA.gov describes. Your tax preparer can confirm what applies. For households, Original Medicare generally does not cover bathroom remodels. Veterans can look at the VA's HISA grant and the SAH and SHA housing grants on VA.gov, and many state Medicaid waivers fund home modifications for eligible members. Our roll-in shower guide lists the current VA amounts.

Installed costs range widely. A prefab transfer shower swapped into an existing tub space is often the least expensive route, and a custom-tiled commercial roll-in with slab work is usually the most. Get quotes in writing.

Hiring for an ADA project

For a commercial job, bring in a design professional who knows the 2010 Standards and your local code, and ask the contractor for past inspected projects. For a home, ask the installer which ADA rules they will follow and which they will relax, and get that list in the contract. Search our national remodeling category or a state page such as Texas, Florida or Arizona. We publish listings but don't verify credentials, so confirm licenses with your state.
