Hi, I'm adding a shower and was goint to use the rolled rubber they sell at
home depot, but someone mention I need a HOT MOP to seal the shower
otherwise it would leak.
I called a plumber and he said he never used the hot mop, only the rubber.
Do I need or not the HOT MOP and if I do, how much does it cost to get
someone to pour it.
I'm in orange county, CA.
