I would like to put a floor drain a bathroom redo, with the shower in a
corner and the rest of the floor sloped to the shower drain. Bathroom
size is about 7x8'.

I've read instructions for shower pans and tiled floors that the slope
should be 1/4" per foot. A building inspector friend suggests 1/8" per
foot in the area of the shower and then 1/16" per foot elsewhere. There
is no code in this state for slope.

If bathroom is formed by lines AB, BC, CD and DA, AB and CD will be about
8' and BC and DA will be about 7.

Right now I'm thinking of the shower in a corner AB-BC with the drain
about 1' from the wall. I'm also thinking of a shower area of that would
formed by a 4 or 5 foot radius from corner B.

A corner toilet will be in the opposite corner. Obviously this has to be
level.

How would you suggest the slope?




I would use the inspector friend's recommendation.
Too much slope in a bath that size makes you think
you're on a sinking ship and looks poor.

If the floor will routinely get wetted down,
remember that water will puddle in the grout lines.
