need a tub

Not really new to RVing, I have a teardrop which I love. I would like to convince my husband to enjoy camping with me now that he is looking at retirement. His need for a daily bath stops him. He tried a couple different times but just didn't like it, thus why I have the much loved teardrop.
Well I remember as a teenager my folks had a trailer, on a permanent lot. It was a 1977 22 foot Golden Falcon. It had the tub shower combo and while not the largest of tubs it would work.
Anybody know of a manufacturer that puts in tubs? Would want to stay in the 22 foot range. I haven't been able to locate one and when I tried to ask a dealer they of course pushed what they have and why I don't want a tub. This is the difference between hubby joining me or not.
