I am starting to install a new shower in my bathroom. I was going to call a “hot mop” company to hot mop the shower pan, but talking to my neighbor’s contractor doing a new patio for him we got on the subject of my remodel and he said that he prefers to do a shower pan liner instead of hot mop. He says that seen when he’s removing an old hot mop shower liner water got under it because the tar would crack because it’s so brittle when cold. Which way do you guys is best, using a rubber liner or getting it hot moped?
