out on the tiles

More tiles installed. The floor of the bathroom is nearly complete:



The shower surround, likewise, is nearly finished:



You can see the logic of the layout here, I think: borders tend to be formed of a row four tiles wide of the smaller tiles with a "pencil" edging. This carries to nearly all the outlines of the various defined spaces, the main exception being the shower surround itself, which omits the smaller tiles.

For grouting, we're using a dark-gray color rather similar to that of the raw base (you can still see it on the ceiling of the shower area), which has two advantages: first, it makes the colors in the tiles "pop," and (more important, in the long run) it's easier to clean than a lighter colored grout.
