Build to floor level, take down the one wall where shower is enclose with close with glass but make it barrier free with seat. Surround toilet are and enclose put a rolling door. Have a stand alone soaking tub id possible. New vanities, mirrors and lighting, make sure the vanities are with a upper and lower level with the lower being handicap accessible. Put in storage for linen.
Why wouldn't this work? Make an option of no lip so it can be a no barrier roll in to/for the shower. tub would have access to at lease cold water and a drain already in place for toilet, just have to connect a hot water source. Bring shower up to floor level. Move toilet to another are, pipe and drain it. New vanities with closet available.
maybe put the tub into where the shower walk down into, make it a sunken tub for Mark. Move the toilet out of area to the main part of bathroom with new pipping and drainage; make the tiolet and shower area a whole wet area with roll/walk in shower for both of us. Make the vanities wheelchair accessible now with toilet being the same with storage. A lot to think about.
