I'm looking at a bathroom remodel. The bathroom is going to get used by little kids. My first solution would be sheet vinyl flooring. It is seamless and waterproof. The homeowner says that it is generally ugly (and I agree). She's seen those snap-together floors (like Pergo), and wonders about them. I figure that anything with seams in it can't be waterproof enough for a kids' bathroom, but I don't have any experience with this kind of flooring. Does anybody know if the seams seal well enough to keep water out of the flooring, and out of the subfloor?
