Hi, I'm having a new master bath built that has a tile floor and tub deck (same tile with same grout color for both locations). The way the contractor built things, the tub deck was tiled and grouted before the floor. The grout color on the deck looks fine, but the grout is much lighter on the floor - even though the grout mix for both locations came from the same bag. My contractor says that the color variations are normal and depends on the weather and how the grout dries. Is this true? And is there anything that can be done to darken up the grout on the floor (ie, a dye of some kind)?
Thanks, Steve
