is always recommended in a steam shower for a more comfortable seating. For built-in seating, a smooth and solid surface material for a bench top maximizing durability and for superior bathing comfort. Many bathers find sitting on grout lines to be uncomfortable. Don’t forget to slope the bench top ever so gradually from wall towards the drain just enough for water to roll and not too much to create seating discomfort. Request the supplier of this material to round the edge/lip that will overhang the seat riser for extra comfort. A seat top designed in this fashion affords greater comfort, is structurally sound, is easier to more effectively slope, protects/shelters the vertical seat riser tiles, and maximizes bench top depth without compromising shower base/floor space.
