MLK, your shower is beautiful, and so is that floor outside the shower! We finalized our tile choices! I am going 50/50: First, glossy 2 x 6 tile (Heath Soft White) for the bathroom where the shower is rarely used. It gets direct sunlight from a window at the end of the tub. For the walk-in shower in the master, a matte 3 x 6 tile (Heath Muslin.) The floor of the shower will be 3x3 in Heath Muslin. (The only custom tile I'm going to need.) I'm so excited that I figured out a way to use Heath Tiles. I have it in my kitchen and it is such beautiful tile. It is particularly beautiful when the light hits it, because each tile reflects the light slightly differently. Their new line, Modern Basics, is much cheaper than their custom work, and best of all, there will be a 20% off sale over Thanksgiving-right before we were planning to do our bathroom. We are going to do unglazed white hex tiles on both floors. (I liked them so much better than the matte glazed ones, plus the square edges match the Heath tiles.) We just have to decide on 1 inch versus 2 inch, or maybe penny tiles or squares. I ordered one of each sample from Subway Ceramics to see how they compare to my local tile shop. (He only has small hex in the unglazed.) Sigh, I thought once I picked the tile that would give me enough direction that all of the other choices would be easy. We did decide on Biscuit fixtures, but which ones??? And then there's the faucets and such... LOL, my head still hurts. Here is a link that might be useful: both colors of Heath tile I'm using are here

I have gloss on my shower walls and matte on my floor. It still can be very slipper

Matte tiles are also fired and glazed and so clean exactly like glossy tiles. (I have a mixture in my backsplash.) I don't think maple cabinets call for one over the other and I also have seen pretty examples of both in farmhouse kitchens.

You are not doing a palatial bathroom like the one above my post. You are doing a bathtub that is also a shower, right? You will have to squeeze just a bit of the ribbon tile on either side of your onyx-look center square, and it will not have the same effect as a 9 ft wide swath of it on the wall next to a freestanding tub with a square of onyx tiles, a ceiling that reaches for the heavens and the light of 8 foot high windows on all sides. It will be a small, dark, dingy cave that you are going to spend hours in, getting soap scum and maybe hard water stains off of textured tiles. And about those 24” wide tiles - your tub shower combo is 30 to 32 inches wide. How do you avoid the “sliver of tile at the end “ effect with 24” tiles? Look at bathrooms that are the size of yours and see how choppy it is to use all those different tiles in one room. I would also suggest you choose either cool grays or warm caramel’s. They do not mix well. Go to the “photos” section of Houzz and do a search on “tub/shower combo” and see what looks you like. Keep in mind that the current trend is toward fewer tile choices and a more cohesive look, no lines of deco tiles cutting walls into sections. If you don’t like to clean, look at Corian, Swanstone, and other solid surface products. Ones that are true solid surface have the same color all the way through, no gloss layer, and can be sanded with a 3M kitchen scrubbie if the were to somehow get scratched or scuffed. I have had my Transolid shower 2.5 years now and never scrubbed it once, just wipe down the walls or squeegee after most showers and clean the floor.
