Nice color choices. I’m a mosaic fan and would use the gray mosaic on both the floors and the niche.

You can't use large format on a shower floor- the floor must pitch to a drain.

What are the vanity tops? I might be inclined to simply omit the charcoal mosaic entirely, use the light one on the shower floor AND the niche if you must have it, and let the bath floor remain charcoal. As I said.........what is the vanity top? And what are the vanity finishes?

Most important? Layout and bath PLAN.

Here’s the current layout.

New will have custom shaker cabinets with black matte pulls and Avenzo quartz and make up bench between the two vanities.

Shower will also have black accents.

I'd skip the mosaic in the niche but use it on the shower floor if it is a good match/blend with the main floor tile.

As @JAN MOYER said, the tiles must pitch towars the drain (and therefor be smaller in order to accommodate the slope).

However, I had the same delimma as I wanted a curbless entry to the shower, with as seamless a transition as possible (visually).

I had my contactor use the same large format tile as in the main part of the bathroom…and just cut it into 6” squares for the shower section (6’ x 5’) with a center drain.

It worked very well, and allowed us to achieve the look we wanted.

I have also seen large format tiles cut into essentially large triangular segments pitched toward the drains, with extra seams as needed depending upon the size of the tile and shower, but this takes a lot of skill and I am not sure about the slip resistance, would depend upon the coefficient of friction of the tile when wet.

^^^ Very good points!

Porecelain tiles are rectified. Don't cut to triangles for a shower floor.

Vanity wall looks a bit cluttered. Raise the make up to ONE COUNTER HEIGHT.USE A STOOL.

I'D re think the lights. The whole thing just seems a lot too busy : ) and dis jointed.

Sorry for the art, you get the idea. LESS.

Personally I don't like the large format tiles shaped to the slope but a good tile cutter can do it rectified or not by slightly polishing the edge. All rectified means is that it is flat to the edge and has a finished top edge. And unless the bathroom is designed to take full tiles without cuts there will be cuts somewhere.

Some tile is sold in different sizes, so see if you can get the floor tiles already pre-cut to a different size that would work better as a shower base. I did a master bathroom using several different sizes of the same tile for the floor, shower floor and shower walls. It resulted in a look that was both unified and interesting. I used 12 X 12's, 12 X 18's and one inch squares. The bathroom I just finished has hexagonal shaped tile on the shower floor.

Love your rug and the hex tile; well, all the colors ... except the gray walls. How about bringing in a small amount of either red or blue ... but not too much; you could overwhelm a small room pretty quickly. OR go red or blue for the vanity. I'd just like to see a little more color somewhere else.

Nice color choices. I’m a mosaic fan and would use the gray mosaic on both the floors and the niche.

I like mosaic too, but with a rather busy rug, I think it could be "too much".

You can't use large format on a shower floor- the floor must pitch to a drain.

Yes, but those hex tiles would be perfect. Glad you're looking at porcelain-marble instead of real. We hear so many bad stories about real marble.

What are the vanity tops?

Depends upon the vanity color, but my first thought is a simple white.

LESS.

Agree -- less is almost always more. Most bathrooms on this site are over-done. Simple and calm will give you a functional bathroom that'll stand the test of time.
