Thank you Bill and Lazarus...it sounds like if there are no major disadvantages with it's use, maybe I will just go for it. I imagine the contractor can find it as it was he that suggested using it. I will tell the contractor what you said Lazarus about it being drier than most and being harder to force into the spaces. Do you have any other hints for this first time user? I read it takes longer to dry...do you know anything about that? I really appreciate any help you can give me. Margie

Prism is quite good grout...better than the basic Custom, in my opinion. Laticrete is also an excellent product, but as you said, the Prism color matches your needs better...

Yes and no. We caulked where the walls meet the floor, which has been an improvement there. Unfortunately a few months after this post a hairline crack started from the corner towards the drain. It was several inches long. I had the contractor come out to fix it and he just dremeled the crack and put more grout. Told me that would fix it. Literally 2 weeks later the crack was back. After having used him for many remodeling jobs over the years, I found out after the bathroom was done that he'd only done a handful of bathroom remodels and usually hired out a tiler, but decided he'd "do me favor" to lower the price doing it himself instead. I'd never have hired him for it had I known any of that. Calling him again for more ineffective patch jobs on this seems pointless. I just want it fixed properly at the point. Since then I had another contractor redo a different bathroom and asked his opinion on this. Within 5 seconds he could see the slope wasn't steep enough for the pebbles. He thought the entire pebble base would have to be removed to fix it, which would be a nightmare as we have a marble bench on one end and it would likely damage the marble walls. I don't have the time or $ do literally redo a remodel so soon. He said maybe we could get some kind of custom colored grout/caulk mix from the tile company to fill the crack and keep it from spreading. With other renovations & a new baby I haven't had time to try that yet, but every time I look at it I worry that it's going to get worse and get so frustrated that something that cost so much has been such a problem from the beginning. Any recommendations would be appreciated.

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