Hello Group,

I've got a problem. I had a new tile shower with tile floor, and a tile bench and a tile bathroom floor installed on a concrete below-grade basement floor. Cement backer board was used on the shower walls but I don't know what was used on the floor or if it was laid directly on the concrete floor. The person that did the tile tells me that the grout does not need to be sealed.

Is this correct?

Thanks a million,
