If a shower floor slope is 1/4″ per foot are other horizontal surfaces also 1/4” per foot?
I have a quick question about how much slope a shower bench or shower dry-off area should have.
The TCNA Handbook states that “All horizontal surfaces, for example shower seats, sills, curbs, etc., must slope towards drain.”
Shower floor slope is 1/4″ per foot. Are the other horizontal surfaces (bench, etc.) also supposed to be 1/4” per foot?
Yes, the correct slope for all horizontal surfaces is 1/4″ vertical (minimum) up to 1/2″ (maximum) for every 12” of horizontal run.
