My mom, Siri, has been working for a long time on the tiles in the bathroom. They were finished in the beginning of May, but no one ever said anything, so I am posting this for my mom. We also have a hand held shower. Now, Mike and Siri are thinking about making a countdown timer on the glass blocks, so anyone who stays in the shower for too long will lose the hot water! They want to make it out of lights, and I am still not exactly sure how it will work.
