End the uncoupling membrane even with the drywall. If you are expecting the floor to be regularly very wet, you can roll waterproof membrane up the drywall a bit and stop short enough for the base molding to cover it, or use tile base molding over the membrane to make it actually waterproof.

Thanks! This is very helpful. Also where does the tile end then? Like where the uncoupling membrane ends?

You probably want a small gap between the tile and drywall, like 1/8”.

Smaller gap than your baseboards. Just think of trim as covering the gaps, so you can make a bit less accurate cuts, and move faster.

My biggest issue was that I kept making my cuts so tight I had to either fit them in place or recut. Instead, just give yourself another 1/8th of an inch and move on.
