In the rest of the bathroom I'm not convinced. When the under floor heating is off they're cold, so you have to pay to heat them the whole time you want to be in there with bare feet. It's not too expensive, but it's power you use. Plastic type tiles with lower thermal conductivity wouldn't need to be heated, and I might go that way next time. Tiles were expensive, along with installation and the heating, but they do look nice.
Keeping the glass clean is more difficult, water spots are hard to remove. Even with a "diamond coating" on the shower (which may be completely ineffective, unsure) we have to use abrasive cleaners to clean the glass.
