I am redoing my bathroom and I have picked the tile I like. It has light grey , cream , and light tan colors running through it. I have pretty much decided on using epoxy grout - the Laticrtete Spectra Lock Pro.

My question is... I would like to use a light colored grout (a bone or light grey) to match the light colors in my tile but this bathroom is right off the garage and we have lots of dirt, etc tracked in. The epoxy grout is supposed to be stain free but is it stain free enough that the grout in a bathroom with this much use (also where we wash the dog) will stay clean? Or should I stick with a darker color grout? Does anyone have any experience with that? Is there any maintenance required for this grout? Thank you so much.
