Attachéd below I have pictures of my beautiful pool. The problem is that glass tile is falling off for the 2nd time in as many years and fortunately the tile manufacturer and pool builder are covering a complete redo under the warranty. My question is this. Both times I have had problems glass tile was used. Is this a problem with glass tile and I should chose ceramic or is this completely a product and installation issue. I love the glass however if it is going to be an issue going forward I would be willing to switch. If you would stay away from glass are there other premium tile products that would produce a similar look that may be more stable? Thanks.
