N.K.
My son hates taking baths as well. In the summer months, we fill up a mini P. (just a few bucks at the Dollar store) that is just his size and fill it with warm water (which requires about six trips back and forth from the kitchen - we use a big lobster pot) and bubbles. We let him brings toys in it, and of course he is able to walk around the deck and get in and out of the tub/P. easily, but it reminds him more of a day at the beach then it does bathtime. I slip in washing him and his hair while he's busy playing, or while he's standing up to get another toy. It takes a bit more preparation, but it sounds like you wouldn't mind as long as he gets clean! :) Hope this helps some!
