LDVPool, You are right, the vertical expansion joints every 8 inches would not be esthetically pleasing, and I have actually never seen it done. And I don't plan on doing it. But I will definitely use the recommended waterproofing membrane, thinset and grout. I also read they require that the glass tile not be immersed for 28 days after being grouted to ensure the thinset and grout have cured properly. That requirement is probably not followed either.
I did change my spa so that is has two vanishing edges that will stay immersed, which as you said, should reduce the chance of thermal shock. Now to find a good quality glass "pool" tile that doesn't cost a fortune.
Tony - it's advised to have an expansion joint every eight feet - not inches. If done correctly, I'm told it should not be obvious. I spoke to one of the guys today who actually wrote the glass tile standards manual and he said that it was important to think of these things to ensure you didn't have problems with expansion and contraction. I honestly have no idea how far away Carlsbad is from where you live, but it would definitely be worth a trip to visit the Oceanside Glasstile studio with all their overstock samples. They have stock in many designs/colors - so there's no waiting to get it from overseas. Everything is made in Carlsbad and is handmade/cut/assembled, etc at their factory. They are only one of two tile companies who manufacture in the US and "anneal" their glass properly. Lightstreams is the other company.
