Hey Kayse,
Great question
Trowel size depends on a few factors
Smaller tile require less thinset to achieve full coverage and makes things eaiser, and if the thickness of thinset doesn’t exceed the thickness of tile it help prevent too much thinset from oozing out of joints when setting (mostly pertains to smaller mosaic tiles on a sheet)
For installing membranes, the size trowel will be specified by manufacture
Generally, I like using these trowels for installing these sized tiles:
I typically use a bigger trowel on a floor so that you have a better ability to eliminate lippage and compensate for any uneven floor areas
A bathroom does typically require a few trowel sizes to accomplish things
If you use too large sized trowel for the membranes…you will end up with a lot of build up making it tough to flatten out, so I would suggest sticking with the manufactures recommendation
Hope this helps
