That pool looks fantastic! I like the way you combined mosaics color with the color of stone that is surrounding the pool.
I am considering glass and stone mosaics. Personally I think that glass mosaic is way much better for water surroundings, but stone mosaics are way better looking.
Anyway I am planing to build pool with marble mosaic, and I am interested if your mosaic have changed in past year due to interaction with water?
