I'm stuck between doing glass tile (expensive) or flagstone on the spillway/waterfall edge of my spa. I love both looks but think I am loving the stone look more. We are doing SWG and my concern, of course, is degradation of the stone (Sahara flagstone) over time from the salt spilling over the edge.
I know there are those of you who advocate no stone at all with SWG.
I'd like to hear from those who went with stone anyway, and have it in constant contact with the water running over it and find out how it is holding up and how long you have had it.
