In response to Re: Hot Mopping a shower - is it necessary?

: OK - we have a remodel going on and the concrete subfloor around the shower is being broken up - we plan on tiling the entire shower, floor and all. The term hot mop has been bandied about - is it necessary? Can't I buy a reasonable equivalent at Home Depot to seal the concrete, or can I use green board? Aaaargh! Thank you!

A hot mop should not be considered. A shower liner needs to fabricated onsite by a professional who has done them before. The "pan" should be filled with water, (2" or 3") overnight to check for leaks before the restoration work begins. Some materials used are membrane material, (there is nothing wrong with this method) sheet lead and copper which are the most undesired materials to use these days. Memebrane may not be permitted by your local plumbing code, so check first. Forget about a hot mop shower liner.
