I don't know what he's talking about. I've always just used bullnose.

Unless he's talking about a countertop trim called "v-cap".

I think he's referring to that v-cap trim. He told me that if he doesn't have that v-cap trim, the side of the tile will be visible and will not look as good around the corners of the window. However, that doesn't seem to be the case looking at those photos.

Can you possibly post an enlargement of that window section? I'd like to print it out to show him it can be done without exposing the sides. Thanks.

Sorry-- what you see is what I got!! I'll see if I can find any other window pics, maybe with a closeup.

Here's the best picture I have showing the bullnose around a shower window:

Perfect, thanks a lot Bill!
