GA has made noises pertaining to a 'walk in tub' to which I answered, "NOT JUST NO BUT HELL NO". The space required for a walk in tub would require a complete demo/rebuild of the bathroom plus forfeiting both a linen closet next to the original bathroom and entire clothes closet from one bedroom. A shower with seat is a possible alternative. We have a shower stall in the basement but it's "not big enough" for her 'needs'. I offered to upgrade the shower stall to one of the bigger stalls with a seat but even that wasn't suitable so at this point, she will continue to clamber in/out of the old tub.
Yeah, I know I'm an obstinate old buzzard but I figure if it's good enough for me--it's good enough for SHE.
