Ceramic Tile – How to DIY Inside Corners for Radius Bull Nose Tiles

bathroomceramic-tiletile

I'm wondering if anybody knows what is the best way (and any links online I may have missed) on how to do your own inside corners for radius bullnose tiles. I have two situations for which I need to find a solution. The solution that the previous owner had was to just smear a bunch of caulk into the corners.

NOTE: I am replacing only the bull nose tiles, not the whole wall.

Situation 1:

Situation 2:

How the wall looks without the bullnose on it:

Any and all helps/tips are appreciated. I just can't find any inside corner pieces for sale, anywhere.

I freehand mitered bullnose tile with a dry diamond blade in a grinder, which was what I had used for all the other tile cuts on that project (after being miserably disappointed with "tile nippers"), so I was pretty comfortable with it by the point I was doing the bullnose. Dust mask, safety goggles, ear protection, work outside if at all possible for dust reasons...

A tile saw might be less prone to error with little practice. Depending where you are getting your tile, the shop might cut a few on their saw for little or no cost as a service to a customer.

It wasn't terrible (either to do, or in looks.) You'll need enough extra bullnose to deal with the losses in making the miter cuts, and any losses in learning to make the mitre cuts. "Situation 1" only takes a little off each half of the corner, and runs a grout line into the corner of the wall.

"Situation 2" eats a great deal more, and will have a diagonal grout line right across the area where that small square corner tile is now. Without the "properly shaped corner piece" I think the diagonal grout line is a cleaner result than trying to cope-cut the mating tile to avoid it.
