Part 2: The picture may need interpreting: I removed the glass door of the shower (the metal bracket and hinges remain), and then used a shower curtain rod (not seen) to hang a shower curtain liner. A bathing helper (me) now has better access with the door gone. The grab bars (vertical one almost hidden) and the bin are held by suction on the glazed tiles. The bath stool and blue donut sitting ring (which helps in access of the nether regions for cleansing, with the showerhead on a hose) were found at a chain drug store.
Except as shown in the previous post, and a new made-for-showers LED light fixture overhead, the shower stall wasn’t otherwise modified. It’s about 36″ x 36″ floor space (90 cm x 90 cm) with a sill that’s 10 cm (4″) high on the outside and 6 cm high (2.5″) on the inside. All told it cost about US$200 (LED light fixture and shower head were the more expensive items).
I’m not saying this is recommended, I’m just showing what we have used. EVERYONE is an INDIVIDUAL. I used to bathe my wife by myself when she could walk and stand easily, but now we have two people.
Safety issues abound with a wet slippery soapy person who doesn’t move well, so consider a “sponge bath” or “wet towel” wipe down instead! If you’re a professional OT person, look away now! That stool doesn’t have a back. We’re getting a shower chair as a next step. After that, we might have to lay out big bucks to remove a tub and put in an easy access, low threshold wheel-in wider shower.
