Pre slope question on shower floor - did I do it wrong?
I recently pulled out a prefab shower floor to build a larger shower. I have a question on the 1/4" per foot from the drain.

This is a 4' x 4' shower. I just installed my Hardibacker and noticed a "sag" in the mortar between the corners of the floor... which is because I sloped the corners higher since the distance to the drain was further than the walls directly across it. Did I do this wrong? I'm talking probably more than 1/4" of gap difference between the corners and middle of each wall.

From what I am seeing; the floor level should be even across-- but seems to cancel out the original 1/4" per foot that everyone talks about.

So brings me to the confusion on how to start the bottom row of tile. They will clearly show the 1/4" gap line in the middle if I dont correct this. Can someone advise on the best way to tackle? I'll be happy to attach a picture tonight if needed.

The slope goes to the drain. At the walls it is all level. So you end up with pie shaped pieces that individually slope into the drain.

Get to grinding and chipping... it needs to be level at the wall-line.
