I have seen it done.....but remember, glossy tile is VERY slippery when wet. Linda c

It doesn't show up in a photo, since it is all white. In person the matte tiles look almost a little grubby next to the gloss like there is a film that needs to be wiped off. And they reflect the colour and light differently. The mix is random but not so random as to look intentional. I think I will just have to live with it.

Yes, that 3rd one is the Barbary Tilebar has it. Comes in the soft white too: https://www.tilebar.com/barberry-decor-mandorla-24x24-matte-porcelain-tile.html and most those others I've posted are from tilebar. have you checked out their site? you get 5 samples for $5. Look under 'large format' for flooring. since you like the grays, do you like this chevron porcelain wood look? If you don't like the chevron, it comes in an 8x48 tile too: Kenridge But, I kind of like it in the warmer maple tone too. comes in this design. great for the bathroom. I like these warmer tones because grays and whites can look too cold and too sterile. So doing something in the warmer wood tones gives it a little depth. Kenridge Ribbon Maple 24x48 I like the first flooring pic you posted but don't you think that room looks really gray? don't know what your decor ideas are going to be, but I'm guessing you like a bit more modern looking? look at this white/gray tile. it's very cool looking. a soft sculpt look https://www.tilebar.com/sculpt-chevron-white-24x48-natural-porcelain-tile.html They even have the terrazzo. I'd do those for the bathroom! they even come in a porcelain that looks like terrazzo. this is from my tile place. I like that white terrazzo tile paired w/this Tilebar Klondike Yukon plank tile. It's 16x48"! so, minimal grout lines. I'd love these last two tiles for a bathroom. maybe the black and white terrazzo just for some more contrast

Yes for glossy in the shower, great! white subway for the shower sides and the marble for the back wall ... kind of run the floor up the wall on the back wall of the shower? When you walk into the bathroom, are you looking straight at the shower wall? a few things to think about. Have you looked for bathroom tile ideas? small mosaic tile accents are too trendy, and don't always last the test of time. Why not just you the same large format tile for everything, including the niche, and so called accent? Classier. I am guessing you don't have the square footage to make the accents mean anything ... photo of the room would help.
