Little background first: I am doing this kitchen and bath remodel here in so. cal. and the homeowner informed me that all there water is hooked into a softner system that uses salt (every hose, faucet,shower etc). not on landscape sprinklers (but no hose).

Here is the question: Does the water softner affect the thinset or grout in anyway?

Tricky question. With thinset, I really wouldn't worry too much. I have never read manufacturer instructions that said add water with a certain pH level. However, if the water is highly treated, I probably wouldn't use it. If the water treatment is unknown, use a latex additive to an unmodified thinset.

As for grout, I would not use softened water. You are potentially asking for efflorescence. Alternatively, you could also use a latex additive for the grout or just get a few gallons of distilled water from the store. It's a small investment in water to guarantee a trouble free install.

OR

Just use QuartzLock II urethane grout. No water necessary! :thumbsup:
