I’ve featured this mosaic bathroom floor tile before on the blog via S.J. Masters in Connecticut but it was kind of buried within another post. But Kate also spotted it on the Nemo Tile website, and this may be a more accessible place for most folks to buy it. I LOVE this stuff, especially for a modern 60s bathroom.

I was hoping to use the gray Nemo tile mosaic “text” pattern. Alas it is no longer available. According to Janice, they have lots of green and about 200 square foot of yellow.
Readers, see all our Tile Resources here, there are alternatives, including likely New Old Stock from World of Tile –> https://retrorenovation.com/category/bathroom-categories/tile/
