Cutting installed wall tile

I am looking for some advice on cutting some wall tile I recently installed. The tile is porcelein and is actually a floor tile I used on my shower walls, over hardibacker. Long story short, I have changed my mind about where I want to transition from tile to painted wall surface, so now I want to trim back a couple inches of the installed tile. My thought is that it would be easier to cut the installed tile and pry off the excess rather than pull the entire last row and re-cut and install new tiles. I've got a rotozip with wheel attachment and regular sized and mini circular saws to work with, but I'm not sure about what kind of blade would work best. I think it would be hard to keep the cut line wet. Any tips appreciated.

Hi Kevin, Welcome!

Do yourself (and us) a favor, and register.

I would suggest a right angle grinder with a dry cut diamond blade. I don't think a rotozip will cut it on porcelain.

I did a minor cut with my grinder, the hard part for me is that it's almost impossible to have a clean straight cut on installed tiles as you have the cuts on wet saw. if you have a lengthy tiles to deal with, I''d think it's easier to remove the tiles and redo.

The other day I was in a Home Depot (I'm in California) and saw a hand held wet saw for $88. It loked like a Skill saw with a water hose coming out of it. It was with all of the other tile saws at the end of the tile ailse. Check it out and see if it would work for you.
