Just stumbled across these very novel tiles that change colour depending on temperature. Check out the photos that shows the tiles installed in a shower. I like a lot! http://www.movingcolor.net/showcase.html
I really like the shower installation. Makes a change from thr run of the mill tiles doesn't it!!! :-D
Hi DiDi, welcome to GardenStew You should be able to get the tiles from the link I provided in the first post. That is the company's website.
They look great, i can imagine they cost a small fortune! But well worth it. My neighbour has just laid a huge patio in his back garden and his slabs do the same thing, they are quite beautiful!
