My mother dated a guy for about 15 years, when he turned very ill, she moved him into her house and we redid the bathroom for him. We made a wheel chair ready shower for him. We could wheel the chair right in, transfer him from the wheel chair to a chair inside, it had two shower heads, both could be hand held if needed. It was all tiled. My mother could stay right in the shower to help him and not have to actually take a shower. This was a much cheaper option then the one your talking about. We thought of the same thing..until all the water drains.. ur getting kinda cold..cold water..not being able to dry off while it drains also.
