I would keep the matching sink if you keep the tub. Change the floor tile with one that is newer but also compliments the tub colors. Sand and repaint the trim and walls a fresh color. Maybe add a counter height storage piece under the window to be used when at the sink as a countertop.

Has the rest of the home been updated?

Not really. Original layout, kitchen needs updating.

i'm not a real-estate agent, but:

I would leave that bathroom basically alone. Remove old caulk around tub, replace with fresh. Fill cracks in wood trim around window and re-paint, or remove and replace trim if necessary. Get rid of open shelving and plastic stuff (stepstools?) around sink.

You are so lucky to have a window for natural light. I say, let it in! Here's a tutorial on frosted/privacy window film that would be worth your effort to try...http://www.younghouselove.com/2012/04/frosting-tanking-sucking-it-up/

Ben Moore's paint color "muslin" righted so many wrongs when we sold our house. It is very complimentary to pinky and yellowy beige fixtures.

You could introduce some color and pattern while hiding clutter by sewing a skirt for the sink. If you have the most basic of sewing skills you can do it... https://bumblebeelinens.com/blog/sink-curtain-diy-tutorial/

If your floor is in good condition, it looks like it's a nice neutral color and worth keeping. The vinyl base molding needs an update, though. When we readied our house for sale, we swapped out the bathroom base molding to Flexco vinyl base in Baby Breath and it's a near perfect match to the Benjamin Moore "Muslin" on the walls https://www.lowes.com/pd/FLEXCO-4-in-W-x-120-ft-L-Baby-Breath-Vinyl-Standard-Wall-Base/50093920

Fix the cracks, recaulk. Paint a fresh creamy white.

Get rid of everything on the sink, except a piece of good soap or hand soap.

Get rid of the bathrobe, the metal wastebasket, the shelves. (Maybe keep that wooden wall shelf; I kind of like the plant, but don' t let it dangle that far down).

I'd get a new framed mirror that covers that metal door (?); I'd get rid of the tooth brush holder.

I'd replace the shower head with something slightly more impressive looking.

What shape are faucet, toilet holder/seat, towel bar in?

I can't tell what shape the light fixture is in, but perhaps replace.

Get a new fancy shower curtain (fabric) and new fancy towels.

What material is the floor? And is the sink the same beige or actually pink?

@YMM The real estate agent is coming tomorrow.

@benjesbride Thanks for the suggestions. I like those ikea shelves!

@nosoccermom The site k is the same color as the tub. They are rosey- beigey. The floor is vinyl and in decent conditon but dated and about the same color as the walls. The sink faucets are in decent shape but dated. The tub faucets probably need replacing.

I would replace the sink with a vanity, new floors, new blinds, paint, new lighting & mirror.
