After looking at the measurements some more I realized that I could probably cram a 30"x60" tub against the wall. That would ultimately increase the value of the home and would negate the need to tank the entire room. I think it would be cheaper to do that than to try to waterproof the whole room and hope that the contractor got it right. The tub install would be simpler. I am wondering about a building code rule I saw on a website from http://starcraftcustombuilders.com/bath.design.rules.htm None of the bathrooms in my house or in my friend's houses have that much space between the tub and the toilet. Does it really matter if the toilet is closer so long as it is at least 15" from the center and there is still 24" of clear space on one side of the tub so that someone can get in and out on the south part of the room? I would want to have more than 15" but am not sure if I could get a full 24". I'm trying to find the IBC code on this but am not sure where I can find it. Louisiana follows IBC apparently.
