You have an Ivory showerpan and your Ivory paint matches it well. You could go a deeper shade of Ivory like Antique Ivory or Golden Taupe for the cabs.

A white marble countertop will tie in the cool tones from the floor and add a luxe look.

You could remove the dated shower door and just use a shower curtain.

It's difficult to tell the exact colour of the new floor tiles but perhaps a taupe paint colour could work for the vanity.

I like Olychick's idea of taking down one column (I would remove the one near the door) but it was too complicate for me to illustrate that way.

As it is now, the floor doesn't match with anything in the bathroom. Behr paint, (& other paint brands) have a visualizer that you can upload a photo & "play" with painting the walls. Likewise, tile stores, like AZ Tile, have a visualizer to show your "new" floor tile with different ideas & colors for the walls.

I agree about removing the tall cabinet on the right, it would open your space more. The shower door does look dated, as does the wood around the mirror. Simple things like replace the towel ring, cabinet hardware, & sink faucet can also give an new look.

I would take an extra floor tile to a paint store or tile store that has displays to get ideas. See what colors go with the floor that you are keeping.

I can't tell if your floor looks like this tile floor, but the blue & gold would certainly give the room a different feel. https://www.build.com/product/summary/1801412?uid=4260501&jmtest=gg-gbav2_4260501&inv2=1&&source=gg-gba-pla_4260501!c1707632300!a68158366538!dc!ng&gad_source=1&gclid=Cj0KCQiA0--6BhCBARIsADYqyL9_bd8Zak3AM12ge0xtFA-ufDTMeGvmEAlElUgUr7XjzyAnA3zC9zwaAkX3EALw_wcB&gclsrc=aw.ds

If it were me i would redo the mirror and countertop/sink and lighting and keep the wood cabinets.

What is the decor like in the adjacent room? Try to create a bathroom that is complimentary.

On one hand, yes to painting the awful wood. BUT, the grain might show through depending on how raised the texture is. Just be prepared for that.

100% yes to the idea of cutting down the right tower or removing it all together. It will reduce the amount of oak you look at if the pattern shows through your paint, and it will significantly open up the room. If you remove it altogether, you should have current extra tile to place in the floor space where the tower was. You can add some beautiful hooks the wall for robes or clothes so the space still has a purpose.

1. My top choice is to color match the vanity paint to the current wall color, or a new similar muted color so they all blend together. Then get a gorgeous counter and beautiful mirror that really become the star of the room.

2. Or, select a color you love that is muted in tone and goes well with your floor and new countertop - a light grey, grey-blue, muted olive/sage, or dusty berry. These will probably look different on my computer than yours but here are a few thoughts:

(With a beautiful new paint color, mirror, counter and faucet, nobody is going to notice your shower door. Keep it. I have a curtain on a shower stall and it is a bit of a pain in the ass. Luckily it is only a guest bath.)

If you’re not a shower curtain type, you can just replace the glass shower door with a frameless glass door. I agree with cutting down the right tower to counter height. I wouldn’t want to remove it completely as the longer counter surface & keeping the bottom storage would be really great.. If the bottom door is a solid 2 level door, the height of the bottom up to towel ring, that top part door might be just right to cover the bottom when cut to counter height. Seems like if some retrofitting needed to make it work, you’d have the materials needed to match in the top half that’s removed. A simple project for a finish carpenter.

So simple it might be hard to get someone to come and do such a small job. I've never been able to find people to do small jobs like this.

Well, yes, I agree with you @Kendrah ! Small jobs do create that problem. But, sometimes we get lucky & know someone who has the skill & the tools to do these small jobs for us.
