.white subway tile with white grout in the shower.
Stained grout detracts from the look of clean tile, so it is best to wipe up spills and perform routine cleaning to prevent stains from setting. A wide variety of brown grout options are available to you, such as classification, usage, and warranty. Last time it was suggested that using purified water for the prep would help, but the grout still turned yellow. The tile and grout here was in a commercial building and was in bad shape, it was originally black grout that turned chaulky white over the years.
