A Built In Bench and Its Slope
A bench is a horizontal surface inside a wet box, which is the reason walk in shower installation lakewood ca nexusphiladelphia slopes the top of one before anything else is decided about it, since a flat seat in a Lakewood shower holds water against its own joint for hours after the water is off.
The Dimensions That Work
Seventeen to nineteen inches to the finished top, and fifteen inches deep for a seat somebody can actually use. Below fourteen inches deep it becomes a shelf for a foot, which is a legitimate choice and a different piece of furniture. Length is whatever the wall gives, but a corner triangle is the least useful of the shapes.
Fall and Direction
A quarter inch of fall across the depth, running toward the drain rather than toward the wall. That slope is invisible when sitting on it and it is the difference between a seat that dries and one that never does. The junction where the top meets the wall gets reinforcing fabric, since it is a change of plane under standing water.
Framing and Load
Treat it as a structure that carries an adult standing on one end. Build it from timber or block, fixed to the framing behind, before any waterproofing goes on. A bench added after the walls are waterproofed means fasteners through the membrane, which is the same mistake as fastening a curb through a pan.
The Floating Version
A cantilevered bench with nothing under it makes the floor read as continuous and is much easier to clean beneath. It needs steel or a substantial timber frame built into the wall at framing stage, and it needs the waterproofing to run behind and around it in one continuous surface. It is not a change that can be made later.
Where It Should Not Go
Directly under the shower head, which turns a seat into a puddle every time anybody showers standing up. Across the entry of a curbless opening, where it interrupts the fall to the drain. On the wall carrying the valve, where it collides with the rough in. Position it on the plan with the drain and the valve, not afterwards.
