Design for the actual user
Needs differ. Some users benefit from a step-free shower, others from a tub transfer arrangement, more turning space, lever controls, improved lighting or reachable storage. Avoid assuming one “accessible bathroom” template suits everyone.
Add support while walls are open
If walls are being opened, consider appropriate structural backing for current or future grab bars and accessories. Record its location before the wall is closed. The placement and design of accessibility features should follow applicable standards and the user’s needs.
Reduce trip and slip risks
Thresholds, floor transitions, loose rugs, glare and slippery wet surfaces can all affect safety. Product slip ratings, drainage and cleaning should be considered together.
Check local requirements
Accessibility codes and standards vary depending on country, province/state, municipality, building type and whether the space is private residential or public/commercial. For a regulated project, use the applicable local requirements rather than a generic online dimension.
