Real marble and faux marble look don't always look the best together. I think you should just go for a plain white hex tile for the floor with a light gray grout. It will complement the wall tile, it's timeless, and it's easy to care for.

No glass on a shower floor. No marble either. Change your vision and find a plain medium gray hex, penny round, or 2x2. It will look much better to have some contrast.

But why are you in this hurry? Has all of the waterproofing and flood test already taken place?

I might worry it would feel too busy/matchy-matchy. Do you have your heart set on hexagon shape? If not a basketweave pattern would work beautifully with your wall shower tile.

Agreed with Sina, a white hex will look the best with your walls.

Thanks all for the quick help. Plain white procelain it is! I will pick some up today.

I liked hex over 2x2 square, but I will look into other patterns as well. My issue with basketweave is the little black squares. Not sure how I feel about that. I was hoping for no contrast because it's already kind of a small bathroom, but plain white can do at this point. The grout is light gray.

Yes the waterproofing is already done. The wall tiles are already put up. They look great. Thanks to this forum all my design ideas. Progress pic:

Get your tiler to pop off those tiles on the top of the curb before they get grouted and are set. Have your stone fabricator cut you a piece of whatever you are using for the counter for that. For the niche bottom too.

Thanks for the tip. I think he has already well into grouting by now, but that's a creative idea that I should have known about earlier.

As for tile spacing, not sure. I didn't specify, so he's just using whatever tile spacers he purchased. I'll check with him and get back to you.

I am researching a white hex to pick up in the next few hours (probably HD/Lowes). I can see a very light gray working as well. I'd like to minimize contrast.

Went to several tile shops. Thought it's a common item, but apparently no one really stocks porcelain mosaics. All I see is natural stone or glass. Found this one at Lowes, and i'll be picking it up tonight:

Thanks all for the help.

ugh, now I'm paranoid again. The specs for the tile says "non-vitreous", meaning it will absorb water.

I just couldn't find the tile. All solid white porcelains/ceramics were for wall and were too slippery for shower use. Not sure how everyone keeps recommending porcelain if there is hardly any selection. I went to maybe 10 tile places today and am finally frustrated.

Ended up getting this and praying that it looks good:

Don’t use that. It’s a warm ivory, not a cool white. It will clash. Use the gray mosaic that is on the shelf there instead. https://m.lowes.com/pd/Style-Selections-Mitte-Gray-Porcelain-Border-Tile-Common-12-in-x-12-in-Actual-11-81-in-x-11-81-in/3800499

Another gray mosaic with just a bit of pattern.

Or the gray penny round. https://m.lowes.com/pd/Style-Selections-Grey-Penny-Round-Mosaic-Porcelain-Wall-Tile-Common-12-in-x-12-in-Actual-12-75-in-x-11-5-in/1000009008

Any of those 3 will work. Pinky ivory will not.

Thanks!

I bought myself a few hours. I got a few more tiles from lowes, including the first one you recommended. Which is best? He will want to start soon, so I don't have much time.

The first photo the floor tiles look too beige with the walls on my monitor. The second photo I do not like the black diamond pieces with your wall tile. The third photo I do not like the dark grey tiles. I am sorry, I know what it is like to be under the gun time wise. I think a white tile that matches your wall is best (like Sina originally suggested is best). Definitely NOT anything marble - ask me how I know :(

You have to get the right tile or you will always be unhappy. The tiler can come back another day and you can live without the shower a little longer. If it is the tiler pressuring you then pay him a little extra for an additional trip after you have the right tile. You will always be happy you did.

Honestly, I would just go for an acrylic shower base..lol. I have 2 x2 marble and I hate it. The grout issue is enough to make my head spin. Would NEVER do it again.

thanks for the input, but we're already at the point of no return. Can't switch to acrylic at this point.

As for those tiles, I agree none really impressed me. I bought another 3 from Home Depot. This is the best out of those. What do you think?

I really like it! Is that the colour grout you are going to use? If so, then you'll be fine. I had white grout...HUGE MISTAKE!

Thanks so much guys! I'm going with it. Bought all the tile, and yes, the grout will be the same light gray. It's under $5/tile too, so I that saves me some money. This is the one:

Thanks for all the help! On every little thing in the bathroom, I used houzz advice. You guys are the best.

Yes, good choice! Happy dance :)

Which did you end up using? Do you have a final picture? Our tile guy is pushing the MSI pietra carrara polished or the polished Carrara. However there is no hex to match the polished carrara-only the pietra. I would love to see a finished photo.
