Slate tile

We grouted our 16x16" slate tiles this week. The slate covers about 400 sq. ft. in our entryway, mudroom and guest bathroom. We decided to use "snow white" grout for a clean, modern look. We are happy with it and after grouting the cork, this was a piece of cake. So yes, we have finished flooring down and no drywall or insulation...seems a bit backwards but we'll get there.
