You don’t say why showers are difficult. Is it stepping over the tub? Some years ago when I was caring for my mom, she couldn’t lift her leg over the tub. We got an extended chair so she could sit and lift her legs and slide over into the tub. That became too difficult as well. The cost of converting to a walk-in shower was daunting but I decided to use one of her life insurance policies to get her what she needed now. We got a removable bench which I haven’t needed yet but soon. So we got a walk-in and now it’s me who needs it. It was a great and helpful necessity.
