cement board as shower pan

my thought: Why the hell would you do this? Cement board is about as waterproof as a sponge.... Is there some special new cement board that is somehow waterproof and non-porous? Don't tell me it's that new foam backer board :no:

I can see the problem with we young folk forming the base wrong as it would screw up the tile work, but there's always a hot mop underneath, so water leakage shouldn't be an issue. I'm still confuzzled

DIYers should be putting in Jacuzzi shower pans IMO, not trying to do a presloped mud base for tile. They're going to do something wrong and cause an issue. The reason the seasoned vets can charge what they charge is because they know what mistakes can cause issues and how to avoid them. A product that can be used by Joe Schmo the HO is not only going to get people thinking they can do their own bathroom remodels, but get more unlisenced handymen doing it and screwing it up too. I guess we should thank you, though. We'll be around to fix the water damage and the poor plumbing, electrical, and whatever else the DIYer did wrong because they thought they could do their own bathroom remodel.

it's hard to tell what of what you said was sarcasm :shifty:
