Where showers are provided, at least one shall be accessible. Showers shall meet the following requirements:
1. The shower floor surface shall be flush with the level of the surrounding area. The maximum slope for water evacuation is 4%.
2. If a shower is provided it shall have a minimum dimension of 865 mm x 1200 mm and have a seat of at least 400 mm x 400 mm. This seat shall be located at a height between 450mm and 500 mm from the floor and be separated from the wall between 150 mm and 200 mm. The seat shall be free of sharp edges. Adjustable height seats are preferred; especially in hotels and residences.
3. Accessible showers shall have a horizontal grab bar to assist in transferring and a vertical one for support. The horizontal bar shall have a length of 800 mm and be mounted at a height of 700 mm to 750 mm from the floor level in the wall beside the shower seat. The vertical bar with a length of 800 mm shall be installed in the lateral wall of the shower seat at a height of 800 mm. The distance between both bars
installed on both sides of the shower seat shall be between 670 mm and 700 mm.
4. Alternative systems such as bath chairs with the same features can be provided.
5. Controls should be within 500 mm of the seat.

Glossary of Terms
The slope gradient of a floor indicates the steepness of the incline. In relation to shower floors, the surface will be sloped to allow for water to drain away. The steeper the surface the more risk of trips and falls for certain users.
Pendulum test value (PTV) is a measurement of the slip resistance of a floor surface, either an external or internal floor of a building. The least slip resistance a surface material is, the more likely people may skid or trip, especially in wet conditions. In average circumstances, slip-resistance is as follows:
0-18 = very low slip-resistance.
18-25 = moderate slip-resistance.
25-36 = good slip resistance.
Light Reflectance Value (LRV) is a numeric scale that is used to identify how much light a colour reflects or absorbs. It is used in universal design to identify the contrast between two colours. This can help to determine if there is sufficient contrast to visually identify a feature such as a fonts on a sign, elevator call button, a handrail and other items which need to be seen by visually impaired people.
