External corner tiling
That situation used to be common in almost every residential job, but that was the old days when for example a tiled tub surround transferred around the corner to wainscot. That's just not done much anymore and the proper trim corners are not available for most tiles except for the old-fashioned ceramic wall tiles. They're still made, but you're limited.
The trims look like this;
You use the bullnose, either the "mud" cap seen here, or the "surface" cap, with 1 piece of AN & AM corner. Confusing to xplain here, but maybe you've got it. Anyway, it's only available in standard ceramic wall tiles.
You'll probably have to go with a double surface bullnose though.
