Manual tile cutter - cutting L shapes out of porcelain tiles possible?

[stoobloo]

A decent manual tile cutter (Rubi TX max) can cut porcelain well, cut what about cutting tiles to go around the face of a window cut out?

Any tips? Tile nippers don’t give a straight edge, nor do electric wet saws that I’ve seen.

A grinder with a diamond blade but practice first if you are a novice as it is easy to go too fast too soon. Alternatively ask your local tile dealer if they can either cut them for you or recommend a tiler who will for a few bob and a cuppa.
