Thank you Kimram :) Which "mood" glass did you choose? Yes, I clean all three materials with the 50/50 solution. Remember, I don't have a shower as mentioned in by the OP. Yes the grout lines are sealed as well as the glass and tumbled travertine. I didn't want to darken the travertine so we used a water based sealer, not an enhancer. Same for the granite countertop. Sealing glass tiles before grouting is important because the fine lines and "crazing" in some glasses WILL be stained by the grout. I don't believe you can seal polished travertine. The sealer can't penetrate. My bathroom floor is 18" porcelain. I use a steam mop on all the tile in my house, including the travertine in the entry. I use a microfiber cloth and the water/alcohol to wipe down the travertine and glass on the walls, on the granite, wipe down appliances, windows...it's become my go to cleaner. Use a spray on granite polisher ever once in awhile. Good luck :) Can't wait to see your beautiful finished bathroom. Monica

True that porcelain tile is a recommended bath flooring material as granite and marble can be slippery. On the walls that are not tiled you could use a light or white paint like here to add a lighter surface somewhere in the room. I searched Houzz dot comm at the Photos link for the words gray slate walls but you could try other words to look for photos that show floors. In the pic after it I like that the shower tile continues on the floor (I believe I've read that there are many porcelain tile options with a slate look).

I believe floor tile size should be proportionate to room/floor size. It will help if you provide your bathroom and fixtures layout. 178sf is ideally suited for tiles no larger than 12x24 to get some character onto the floor. Our master bath is around your bathroom size and we selected 12x24 satin tiles in straight layout for its floor with a dark grout and 12x24 polished for the shower walls also a straight layout with white grout. Large format tiles typically look better in larger spaces. As an example We used the same but 24x24 satin tiles in the kitchen (1000sf+) and 24x24 polished in our entry/foyer (600sf+) both with white grout.

I am looking to do something similar in using a polished large tiled very light veining porcelain tile on wall and sane design large tile matte on floor. The actual shower floor will be a stone. My question is I will have a very low lip divider from shower to bathroom floor and the matte finish on the stone is similar to the matte finish on the bathroom floor and more importantly, the two look beautiful side by side so I think I want my lip to be matte not glossy. Any help is appreciated. Can I do the lip inayte to match the floor not the walls? Also I was originally thinking to do all matching matte walls and floor for a natural look but bathroom designer suggested glossy for the walls. Not sure I am sold and have to pick soon. Help!
