Samara, over the years we have traveled with my MIL a lot. I find that there is a WIDE variance in what hotels/motels call a handicapped accessible bathroom. Some are nothing more than handgrips installed on the wall and some are just great with fold down benches, handheld shower heads, bathroom heaters, raised toilets. There is no consistency. I'm also amazed that such rooms are ALWAYS on the upper level floors. How in the heck are we supposed to evacuate the room in case of fire? Cannot use the elevators. Wheelchairs and walkers down several flights of stairs??? Really?? So far, so good, but still I worry. I wish more thought went into design for the elderly.
txcamper--"Soapboxes" are fine; I've been known to get on one "occasionally"! I didn't realize that so many of the handicapped rooms tended to be on upper floors, so thank you for making an excellent point.
Jumping back to Sonny's comment- the Safeway tub people can cut out the tub wall for easy entry- pretty inexpensive. They also have a version with a door for the hole so it can still be used as a tub. The "walk-in" tubs that are being advertised can be very expensive but the choices above are much more reasonable.
Yes, your Dad requires help in the shower. A bath bench with adjustable legs is a good idea but make sure that the it is securely assembled. If installing bath aids in the home or condo, ensure that it complies to proper property standards.My mother used a secure bath bench with my help in our condo; I was home at the time when she was age 92-93 before going into assisted living arrangements.
Now I'll get off my soapbox, sorry.
Don't forget the non-slip bath mat, not the spongey variety.
