I think this could work. It would help to see a layout of your bathroom and an image of your tile and wood choices.

If teal isn’t doing it for you that blue color is really pretty too and still would look gray with brass and the grey floor tile! I found a few good options on amazon for the hardware by searching brass square pulls and also these on way fair: https://www.wayfair.com/Hamilton-Bowes--Ventoux-5-Center-Bar-Pull-24128SB-24128SCOP-L1123-K~HMBW1035.html?refid=GX293766718941-HMBW1035_40348394&device=m&ptid=762818256643&network=g&targetid=pla-762818256643&channel=GooglePLA&ireid=83020192&fdid=1817&PiID[]=40348394&gclid=EAIaIQobChMIsbjP3fmW5AIVgrfsCh1oWwbcEAQYDSABEgIS_PD_BwE Here is a link to a similar light fixture! https://www.bellacor.com/productdetail/elegant-lighting-ld6042br-eclipse-brass-and-frosted-white-12-inch-one-light-pendant-2116486.htm?partid=googlePLA-DataFeed-Pendants-2116486&kpid=2116486&utm_source=google&utm_medium=cpc&utm_campaign=Shopping_-All_Products(NEW)&utm_term=&utm_content=multi-converters_(2-5)&gclsrc=aw.ds&&gclid=EAIaIQobChMIv_64qPqW5AIVFKrsCh0HGQGgEAQYCCABEgJyK_D_BwE I think the subway tile will look classic and gives you more leeway to get a countertop that can be the star! If you picked the geometric backsplash I would say go for simple very toned down counters.

I like the same tile for bathroom floor and shower walls usually in 12 x 24 porcelain .I do not like marble for shower anything and I aslo do not like niches . I think simple is the best plan for longevity.I also do not like any pattern in the floor and wall tile. You can add ab accent stripe on the shower wall in a vertical install and then use that tile for a backsplash if you want a bit of accent. I like a stacked pattern for tile and matching grout.

I believe the difference in color is too great with the white and brown. Why? 3 reasons 1. The products that are cemented to the building you will not redo anytime soon. Messy , dirty, expensive and just not worth the trouble  2. When you add a product to the building structure. Windows , floors they must last a long time. Durability, wear and tear, and STYLE. All equal a story of when the home was designed.  The look over a period of time 10 years + and the home will become "out of date" Needs a face lift . 3. The homes we admire, the Museums, Churches, Libraries, Opera House have one common thread. At a glance they are timeless. Built in 1940, 1990 etc  The crystal clear item is not seen  For this reason I would not go "trendy". Generally our first choice is the right one. Simple and elegant  How do you change this ad time moves on. Color Bedroom a change of bedspread. Bathroom towels become a dark navy or  deep forest green. Yellow for spring  Paint a wall blue, hang a piece of art  The change is simple and your money well spent for resale  Take a moment to do another board  Remove the brown and replace with a neutral. Try an Odegard runner - There are so many options  Enjoy
