We are remodeling the late 60's/early 70's bathroom in our 100year old home. The current shower/tub combo built-in was not original to the house and was added by a previous owner remodel. It is an odd 57" length. We want to replace it with an alcove tub and tile the surrounding 3 walls. The mega home improvement store tell us the only option is to buy a 54" tub and to build out the walls to make up for the 3 inches. The only wall we could cut into to expand to a standard 60" tub would require major replumbing that we want to avoid. We can't believe we are the first to encounter this dilemna. Does a 57" length alcove tub exist anywhere? We'd really prefer to not do a clawfoot/freestanding tub since that makes showering, its primary purpose as opposed to bathing, much more difficult.
