When building a tiled shower floor with a traditional mortar bed and drain, the finished floor should slope toward the drain at approximately what minimum rate?
a.No slope is needed if the tile is sealed
b.About 1/4 inch of fall per foot toward the drain
c.A steep 2 inches of fall per foot
d.A reverse slope away from the drain
Giải thích
A shower floor should fall about 1/4 inch per foot toward the drain so water sheds and does not pond. No slope lets water sit, 2 inches per foot is far too steep and unstable to stand on, and sloping away from the drain traps water against the walls.
