Thanks Pepperidge Farm, that helps! I have seen and admired Casey's gorgeous bathroom before. Never really noticed the grout ,though. I would not be concerned about using different grout colors if the wall and floor tile were not both white. I would love to replace the wall tile, but it's not currently in the budget. So, I definitely want it to fade into the background. BTW, I love your bathroom. I have been lusting over your shower glass. We have basically the same configuration as you, glass w/be80" high,etc. We are getting our glass installed on Saturday, and the glass guy is recommending we put metal clamps on the corners instead of just relying on silicone. I keep seeing your beautiful glass, however, and much prefer the cleaner look. Anyway...thanks again for the color advice, definitely not my forte.

I used the Warm Gray you're referring to, with white subway tiles from Lowes. I really like it. It helps the tiles to stand out, but not too much. I had white square tiles, with white grout before, and it just looked solid white. The warm gray is a good medium color. I would choose it again:)

Figuring out colors on computer screens is tough. Your tile shop should have sample grouts that you can set up for comparison, or your best bet is to hire a designer to help you. Here's a story on Houzz on how to select grout: https://www.houzz.com/magazine/what-grout-color-should-you-choose-for-your-tile-stsetivw-vs~89929909

I have difficulties when I click on a phot and it comes up smaller. And I don't see any tile samples next to the counter material. How about some really big closeups?
