How to Waterproof a Shower Seat
Bathroom seats are often made out of tile, marble or granite because of their beauty and water resistance. While the seat itself may be made out of a waterproof material, this doesn't meant that water can't find its way behind the chair. Waterproofing a shower seat will prevent moisture from seeping behind the seat and molding behind the tiles. You should already have the seat built and will waterproof it prior to placing your finishing materials on it. Does this Spark an idea?
