I propose purchasing from Amazon prime four Moen 8724 Home 24-Inch Bathroom Grab Bars, Stainless, one for each bathroom, and to ask Tim to install this grab bar vertically with its lower end 36 inches from the floor on that stud which is closest to the center of the rear wall of each shower and of each tub enclosure.

I infer from my own present condition that such a grab bar would be essential for safe showering. Since there are no conditions under which I myself could sit in the bath tub, I have no suggestions whether or where a bar should be placed (additionally) to facilitate negotiating a sitting position.

Please advise and consent.
