Minimum 1100mm X 1160mm. 100mm recess for shower base.
Wheelchair users who use moveable seating prefer 1200mm x1200mm with a flat floor, sloping to a drain 300mm from the corners. This also allows ample space for an assistant.
NO HOBS. Curtains preferred. Outward opening or sliding doors are permitted in some situations.
Grab rails in wet areas must always be stainless steel as chrome rails become very slippery when wet.

Horizontal rails must be 800mm ‑ 810mm high
The range of grab rail configurations is beyond the scope of this guide.
