I used some walnut colored grout 20 years after the tile was laid in a bathroom. The hardwood guys cracked a tile in the bathroom doorway. We found the old grout bag up in the attic and it matched perfectly! As long as it had been dry, no problemo. -Babka

Guest bathroom shower surround, glossy white tiles, "regular" TEC grout, 2008 I think. MB and hall bathroom tub surrounds, glossy white tiles, TEC XT grout, 2011. No issues. The XT grout doesn't require sealing, but can be, using a solvent based sealer. We have moderately hard water. We wipe down the tub surrounds with a microfiber cloth after showering (to prevent water spots on the glossy tile). I clean the bathrooms pretty much weekly. I spray the tub surrounds with 7th Generation disinfecting bathroom cleaner spray. Let sit a few minutes, and wipe dry with a microfiber cloth. Tile and grout look as they did when first installed.

I just last Friday had both my walls and floors (I have the same large format tile on the walls as well as the floor) grouted with Mapei Warm Gray. It's gorgeous, I love it on the walls, but somehow I'm finding it a little to light for the floors, even though I like and wanted a uniform look. Don't get me wrong, I'm very happy with how the bathroom is turning out, but I think I'd have gone a little darker on the floors if I had it to do over.

Hi. What did you decide to do here? Looking for light grey from prism.
