6. Install a Curbless Shower
Any obstruction, even if it's just an inch high, can be difficult for some people, so a roll-in shower with no curb is best. To avoid water getting on the floor, you have three options: Build a shower area large enough so you can create a gradual recess to the drain, raise the floor of the rest of the bathroom, or install a drop-in shower with a flange that can be lifted up to serve as a curb when someone is in the shower. To make getting in and out easier, you'll also want to leave plenty of room around the shower, meaning spacing cabinets and toilets at an adequate distance.
