Some unmodified gray thinset and water, some time with the tile saw, and…
here we are!
We’re using 3/16″ spacers between each of the 13×13″ tiles.
The thinset is currently drying, so we’ll be able to walk on it to measure and cut the last couple of corner pieces in a day or so. After that, we’ll just need to grout and then the floor will be finished and ready for toilet installation. (Yay!)
