Correcting a shower pan slope & drain height
We're in the final stages of a DIY bathroom renovation. A plumber built a mud shower pan for us when we had the plumbing roughed in, and now that we're about to tile it we're noticing that the drain is too high (i'd guess by about 1/2") for our tile, and the slope seems to put the low point a bit away from the drain.
Is this normal? Should I correct it with thinset, or apply additional mud?
