why cut a square when you can drill a hole in the tiles in seconds with the 365 drills...have you used them yet Biffa?They are excellent..loads of holes on ceramics and a good few on porcelain.
I guess it depends on the size of tile being used and where the grout lines are going to be. Whether you drill 4 holes or cut out a "T" shape, just so long as it's sufficiently covered by the cover plate and that you can still get access to the inlet filters, temperature control cartridge and the flow control for future servicing or repair.
