whoa. I haven't seen that color since the 60's.

can you afford to throw a few hundred at this space?

can you DIY paint the vanity and add new hardware?

new mirror? maybe a new light?

new toilet?

For 400, you could get a new vanity/with a top and mirror, a new light, and a new toilet.

for another few hundred you could get the tub sprayed white.

maybe some shelving or art over the toilet? That 70's oak towel holder just isn't working.

you can make this for about $25. get the brackets and wood at home depot

you have to be careful w/grays. you wouldn't want a blue gray. and really, gray isn't the best color w/everything else you have

I'd prob pick a white that matches your shower curtain and decorate w/greens.

Pick a white:off white that is similar to the tiny white tile on floor. Paint vanity. New shower curtain and bath mat- maybe some thing geometric that brings in the yellow. New nickel hardware.

@Beth H. :Yes I can put in a few hundred to make this space look better! Thank you for the suggestion on white matching the shower curtain, I'll do that. You mentioned to paint the vanity and add new hardware - any color suggestions there?

You could actually do this for under 500. (not the sconces though. just a inexpensive light over the mirror )

ignore the black. but the ceiling you could do in a glossy color picked from your floor tile. paint the walls a bright white. get a vanity like this. look on craigslist for seconds, or even an oak one you could paint yourself. some come w/tops. if not, find a remnant for $50. new faucet, install yourself. toilets are cheap. find a rug. the gold hardware goes w/the flooring. keep the curtain pulled over the yellow tub.

try painting your vanity

give it a good sanding, 150 then a 220 grit. wipe clean. prime. now paint a cool color. get new hardware and find a new sink top w/sink. (maybe $150

Find a new mirror, or look at DIY on how to frame yours w/wood or molding

make these shelves for over the toilet. find left over wood, cut, sand and stain. brackets are cheap

To minimize the effect of yellow, do not be tempted to add anything into the bath which is yellow.

Yes, to a gray wall:

B.M. Rodeo will work with the yellow

As for the towel rack, I think it is too close to the toilet when it is flushed.

(Journal of Applied Microbiology found that microorganisms reached a vertical height of 2.7 feet after a toilet was flushed)

Then paint the vanity a dark, dark purple in a gloss finish.

B.M. Shadow.

Next a new shower curtain:

My old house had a tub and toilet that color in one bathroom and a toilet and sink that color in another powder room. If you have the budget I cannot more highly recommend replacing the toilet and vanity and spraying the tub. If you don't have the budget for those changes, perhaps a soft cream color would work well with the yellow. I would definitely not do gray or silver because it will make the harvest gold more prominent and I'm sorry but that's the last thing you want.
