If cheap is your objective, wouldn't it be cheaper to buy one of those fiberglass shower pans for about $50 and then you don't even have to tile it?Your question that if doing something cheaper is a good enough reason to do so,my comment is
some of the clients that I work for their whole budget for the bath is $5000.00 some of you may call it foolish for me to do their work, I call it ministry. They just can't afford to pay more. So, with that as a backdrop, I do think doing a shower for less cost is a good enough incentive to find the alternative that I have found. I WILL make it public and take the shots in Sept.
