We are looking at "waterline" tile for our pool and I have fallen in LOVE with the glass tiles. Some of the pools I have seen on this forum, in the last few weeks that I have been researching, all have the same thing in common-this tile!! Can anyone that has ordered this tell me how long it took to receive? Does 3 weeks should correct? We have talked to our tile man who says he is experienced in this tile but anything we may need to know about mortar? curing? grout? Thank you!!
