ADAAG Manual

Bathtubs [4.20]

ADAAG allows provision of either tubs or showers in accessible bathing facilities. Where provided in accessible bathing facilities, at least one tub or one shower must be accessible. Note that where tubs are provided, a securely fastened seat (which may be "portable") is required.

Clear Floor Space [4.20.2]

Clear floor space at tubs, which is dimensioned according to the approach, may overlap required turning space within the room. ADAAG allows a lavatory on the same plumbing wall to overlap the clear floor space at the tub because knee and toe clearance is available below an accessible lavatory. If located to overlap this clear floor space at the tub, a lavatory must not project into the tub clear floor space more than 19 inches. Recommendations: For easier access to controls, it is better to locate a lavatory beyond this clear floor space. For seats at the head of the tub, consider additional clear floor space to allow positioning for side transfers.

Grab Bars [4.20.4] and Controls [4.20.5]

Controls must be within reach from outside the tub and cannot interfere with the use of the grab bars. Tracks on the tub rim are not allowed as they can interfere with the transfer to tub seats. Dual grab bars on the back wall are needed for transfer to the seat and into the tub.

Seats at the head of the tub are limited to a 15 inch depth so that back support is available from the side wall (which is why grab bars cannot be placed on the seat wall). Dual grab bars on the back wall must extend to the edge of the seat for use in transferring to the seat and for lowering oneself into the tub where one is able to do so. Recommendation: A hose for shower spray units longer than the required minimum of 60 inches is recommended for easier use of the shower spray unit from the seat.
