cute bathroom. well, obviously art comes to mind. something with yellows/whites/grays/blacks.

but if it comes out to far, people walking by many hit them.

What if you painted the wall an accent color or did a stencil or geometric design?

here's a stencil design in your colors

or you could do a geometric type of wainscot in white with a yellow background. somewhat like this one

you can choose to leave the background white and paint the wood, or vice versa.

the honeycomb design is also cool. you could do an ombre effect with with the gray or the yellow,,,darker at bottom and lightening at the top. or do them all in white with just a few in the yellow

do you plan on using any baseboards?

Love your tile!!!

No baseboards. Totally modern.

The tile above the vanities will be the yellow and white penny tile in ombré pattern to ceiling, so I’m going to stay away from ombré on this wall.

I like the stencil idea, but I doubt I would be able to make it look really good, so I’m thinking a funky modern wallpaper might be easier. Not sure what kind of hooks too.

i'd prob just do a modern type of robe hook.

wallpaper is a good idea. forgot about that! that leaf stencil pic I posted is actually wallpaper. I like the colors in that one.

this too is a wallpaper. similar to the honeycomb i posted.

Keep it simple for a young man. Hooks instead of towel bars and a minimum of decoration. The function is everything.
