I was planning to use gray. I am using Polyblend but was wondering which color would blend better with Catarina tile, the Platinum or Oyster Gray?

So you mean gray throughout, not white along the tub. Thanks. Do you know which is lighter gray, the Platinum or Oyster Gray in Polyblend grout?

Use the same color grout throughout the space........I think that oyster gray is lighter, but not sure. I know that I have used it in the past and it is a good color.......

I always prefer the lighter grout.

Looking at pictures I can't tell if the Platinum or Oyster Gray in Polyblend is lighter. That's what I'm trying to find out.

What did you end up doing? I am having the same issue. Any advice would be appreciated. Thanks!

We used 1/16" spacers which makes the space between the tiles very small. We used Polyblend Platinum grout (special order through Home Depot). For the caulk we ordered a caulk that was colored to match Polyblend grout. They had a color intended to match Polyblend Platinum. We ordered that online from the following website: www.installerstore.com It's also known as Rugrats Flooring. Attached is a picture of the caulk around the tub and the grout between the tiles around the tub. Hope this helps. Make sure your contractor specifies sanded or nonsanded for the grout as well as the caulk.

Thank you that looks really great!
