Water leaking from our shower into the laundry room on the floor
We just installed a shower in our basement. We used marble 12" tile for the walls and marble 1" tiles for the floor. We did a flood test by plugging the drain and filling the pan with water. It held and did not have leaks! The problem is when we open the drain and run the shower. The water slowly moves into the laundry room floor. COuld our drain be too high, or cracked? We installed the tile right onto the concrete floor in the basement.
