honest? it looks like floor tiles. not loving it.

Can we get a wider shot of the whole bathroom? It's hard to judge based on one picture.

I'll ask my boyfriend to hold the tiles up while I take a wider pic! I'll post it either tonight or tomorrow :)

I think the size looks good. I would use a white grout.

I think it looks good, but something on the magnitude of 4" would look really good. Zoomed out picture would definitely help.

After seeing your doors in the reflection

I like the hexagon!

If it's just going behind the sink, I think it looks great. I agree with everyone else on the grout.

We are leaning toward the larger tile with same color grout. If you are worried about the upkeep of white grout try Mapei MAPEI Flexcolor™ CQ.
