Consider having a bathroom on the floor level to avoid needing to use the stairs to access your restroom.

If you or a family member relies on a wheelchair, make sure the bath has a 60-inch turn radius and either 36×36-inch or 30×48-inch clear space for maneuverability.

Install a curb-free roll-in shower or walk-in bathtub.

Install grab bars and make sure your support walls can handle the pressure and weight. Add support braces if necessary.

Install or purchase a shower seat in the shower.

Apply anti-slip coating on shower or bathtub floors, as well as the bathroom floor.

Plenty of lighting (but not too bright), including a light in the shower if needed.

Scald-proof faucet and shower accessories to prevent the water getting too hot.

Install a height-appropriate or handicap-accessible toilet.

Install a hand-held or adjustable shower head for accessibility and ease of use.

Consider installing a wheelchair-friendly, open-spaced sink.

Install a bathroom phone or intercom in case of an emergency.

Install bathroom locks that can be unlocked from outside.

Install toilet paper holders that can be changed with one hand and that can be reached from a seated position.
