We have been inundated with these commercials lately. They proudly display some of the shoddiest work I have ever seen and I am no contractor. Tonight's commercial showed them taking the walls down to the studs and covering them with thin plywood. Shouldn't shower walls have some kind of waterproof cement board behind the finish material? They then apply some really cheap looking paneling over the plywood and caulk the seams.. Double Yikes. Who knows whatever sins they are hiding. I feel sorry for whoever falls for these advertisements.
