I have light colored Energie Kerr Italian matte porcelain wood look tiles in my bathrooms and slightly darker ones for my entryway hall. They are so easy to clean with Mutphys oil soap and water. No issues!

I have porcelain tiles in my master bath that are not glossy but not fully matte either...more of a satin. They are no more trouble to keep clean than glossy. I would think that, unless the surface of a matte porcelain tile actually had texture to it, the amount of care needed would be no different than that of a glossy tile. The important thing to remember is that glossy porcelain tiles can be too slippery to safely use on the shower floor, unless they are rather small so there are a lot of grout lines to provide safe traction.

We had marble look Crossville porcelain tile with an unpolished finish in our last home's primary bathroom with different sizes for the floor, shower walls and shower floor. The tile was very easy to clean.

Our new home under construction has large format porcelain tile floors that aren't marble look but are very light. Despite the ram board being removed too soon and red clay getting tracked inside by various trades, the cleaners seem to have had little trouble getting the floors clean again (and again.)

The only thing I will say is that it sounds like too much of a good thing if you put the same tile everywhere. Also, I have seen pictures on this forum of tile jobs where the installer didn't pay attention to the way the veining lined up and made a very unattractive pattern, so keep an eye on your installation as it goes along. Do not wait to look at it until after it's grouted and it's too late to change it.

Thank you so much! Yes I am rather worried about how complicated it would be for me to line up the veining, would I know how to do a good job? It was going to be a mosaic floor, which would be easier to line up but harder to live with. I thought maybe one alternative is a shiny white faux Thassos floor, or wall, so one of them (floor or wall) would be quiet; but would white color coordinate well with calacatta look? I'm also thinking of going with 24x48 so that it would be easier to line up the veins. Thanks everyone!
