Here's another photo -top white grout bottom LITOKOL keep in mind this was a sample and the grout is not cleaned. The tile was already messed up from the white grout and some of the white grout was removed, we deiced to start over again this tile will be removed and retiled using the LITOKOL crystal grout.

Please make sure your builder puts in isolation joints in the tile with a silicone that is rated for submersion. Glass tile is prone to cracking with temperature changes with half the tile being in water and the other half being exposed to air. The isolation joints helps relieve the expansion and contraction of the tile.

Laticrete is the only one that I know makes the silicone that is rated for swimming pools. It's called Latiseal.

Hope this helps.

This stuff is used for pools all over Europe and is supposed to be much better than Laticrete. Its part epoxy and has some sort of thermal expansion in it. Again, it's new to this market. I'm glad I found it because I would rather use a clear grout that morphs in my tile than use a colored grout for my glass tile. This brand has colored grout too with glimmer in it, but the crystal grout they makes is amazing with glass tile.

So much better! White grout is terrible on anything other than white tile. We have cobalt blue tile, and they were going to use white grout. So glad I caught it. Then they wanted to use some blue or grey that might or might not have matched. I had to push them to use black grout. Very glad I did. Looks great.

A lot of people seem to think that white is invisible but it's only invisible on white. On anything else it's a sore thumb!

A similar thing happened to us with some kitchen floor tile. It was pre-cast/pre-finished terrazzo, and the company had very specific instructions about installation and a very helpful rep to answer questions. I gave all the info to the contractor. He ignored it and then wanted me to pay him to do a normal polish finish like they would do on unfinished tile. I refused and live with imperfect tile because the alternative was ripping out the kitchen and starting over, and a legal battle to get him to fix it. At least I refused to give him extra profit.

About changes... Yeah, they treat every change like you're an indecisive idiot and act like they've never heard of such a thing and they use it as an excuse to charge big for it because you have no alternative. They use change orders as their personal ATM machine. I'm not sure how to avoid that, except to have an agreement about competitively priced change charges before you start.
