Adapting a shower stall wasn’t too bad, but made a big difference!
This photo shows a new dual showerhead, pump bottle dispensers , and a grab bar. The old showerhead just unscrewed, and this combo of one fixed and one flexible showerhead on a hose (almost ESSENTIAL for helping someone!) just screwed on; I used that white plastic plumber’s tape for a good seal, hand tight. The rubber hose ones are cheaper, but don’t stay on well. If you’re not tall (I’m not) make sure your step stool is sturdy, DO NOT use a FOLDING CHAIR! SAFETY means YOU TOO.
Note the pump bottles of body wash and shampoo, so you can get some with one hand. Really more useful than slippery bar soap or when one hand is already occupied (with the showerhead, etc).
I tried several brands of suction grab bars; this one stays on for months, but it’s more related to the kind of tiles we have, and the size; I tried others that didn’t work. Got all this stuff at either hardware stores, chain drug stores or at a chain bed and bath store.
