Using 1-1/2” HYDRO-BLOK Building Board, you can easily install a corner or box-style shower bench in minutes with very little cost.

  • Using the diagrams below and a saw or sharp utility knife, cut the pieces required for your shower bench.
  • For corner benches, cut a 45º degree on each end of the front panel.
  • Dry fit all parts to ensure fit and then use generous, continuous beads of HYDRO-BLOK Joint Sealant to assemble your bench and secure it to your wall board.
  • Ensure the bench top is slightly angled down into the shower to ensure water drains properly.
  • Allow the Joist Sealant to cure for at least one-hour and you are ready to tile!
