a walk in tub and shower (as in stepping into it through a door without having to climb over a high rim) has nothing to do with ensuite bathrooms and is actually a pretty cool invention!
My parents are in their mid-70s and are currently considering to install such a thing. It's more comfortable if you're walking impaired and the risk of slipping and falling is smaller, too. I once had one in a hotel room - loved it!
