i have a step down of around 3-5mm along its length of 2m at a door way, as i was drawing this diagram i thought of a solution, the tile that is at the bottom of the step i could grind a mitre on that side and put a bit more glue under the front mitred side to bring it up to the level of the tile at the top of the step so there is a small slope coming down to meet the bottom level.
anyone else think of abetter way??
