Procedure for Hot Mopping Benches and Seats
Benches and/or shower seats add comfort and beauty to your shower. These areas need to be fully sheeted or blocked on the face and top and have vertical backing at all walls were the seat face meets the shower walls, this needs to be a minimum of 3-1/2”. Where the bench top meets the wall 5-1/2” is the minimum blocking requirement here.
Benches and/or shower seats can also be made of concrete and/or block. If installed after the mop, make sure that the walls were the bench will meet the wall have solid backing that extends a minimum of 8” above the finished height of your bench.
With free-floating benches the walls below the bench area need to solidly backed/blocked up to the bench before the mop is applied.
