avoiding floods with handicapped shower
I posted in April about a bathroom renovation I'm planning for a disabled relative. I have a contractor ready to start next week. He ordered a barrier free shower and sent me the specs on Monday. In teeny tiny print is this: "Exterior floor drain is recommended." I called the manufacturer (Florestone) and asked about this. The rep said that if you leave the water running, it will overflow. It's meant for the water to be run only intermittenly. Well, I don't think my cousin will keep turning the water on and off; he's going to let it run. There isn't going to be an exterior floor drain. I had decided on vinyl and you can't do an floor drain in the middle of vinyl. My cousin uses a walker and can step over a small threshold to get into a shower. I'd feel a lot better if I know the water is staying inside the shower and not getting all over the bathroom room, making it slippery and possibly flooding the house. So I want a shower with a threshold. But I also want one with grab bars and a folding seat and the sliding bar and hand-held spray and anti-scald valve. But it seems those things come only on the barrier free models. What can I do? I've read about semi-permanent thresholds that apparently can be added over the small rubber lip to make a threshold about 2.5 inches high. Looks like they're attached with silicone. Do they hold up? Do they work? Or should I look for a normal shower enclosure and plan to add grab bars and a seat? Is there any problem with adding grab bars to a new fiberglass or acrylic shower? You need backing for the grab bars. How should that be added?
