Sorry -- couldn't get the rotation of the 2nd image corrected.

Not considering house the rest of your house is decorated or your preferred style, he short answer is yes you could repaint and remove the window treatment. Are the tiles neutral (beige, taupe, tan) as they seem to be a bit pink which can sometimes be a problem? If budget is not an issue, I would have the floors and vanity top replaced, add wainscotting and then paint the upper wall a colour that you like (lighter and brighter). You could even stain your vanity darker.

But if there is a budget (when isn't there?) I would try to work with the floors and vanity (as is) and then bring in panel moulding and wall paper and put down a woven rug to detract from the floor.

Here is an easy interpretation of a face lift:

Change the vanity top and add a back splash to the sink. Change the faucet and hardware and paint the walls a much lighter neutral colour to blend with the floors. Add a chandelier to the bathroom. It makes it feel like a hotel. And artwork.

By new towels that match and keep those for the power room (I always buy extra and keep them in the vanity for quick change outs)

Or a mid point budge conscious splurge is to do a bit of both.

Panel Moulding, repaint, new counter and sink, faucet and paint the walls.

Add a rug, change cabinet hardware

Definitely paint lighter and add the wainscotting if you can. Tile can also act was wainscotting and is easy to clean.

Enjoy.

Depending on how much you want to invest...

My first suggestion would be to get rid of the fabric valance - you are blocking the natural light from getting in. I would also get an electrician and get a beautiful ceiling fixture and go to a smaller mirror with a sconce on each side. Look into regrouting the floor to a color that matches better and paint. You also could use some bolder pieces on the wall - the space looks very empty.

Good luck!

I’d start with cleaning the floor and grout lines. Then find a really cute rug for in front of the sink, and pull colors from the rug for towels, a valence, wall color, etc. Maybe change out the hardware and light fixture. Looks like you have a small child using that bathroom, maybe let him/her get a little older and less messy (although it’s a clean looking bathroom) before doing a major overhaul.

Agree with others, esp applie_pie_order. Also agree that it's good to consider the style of the rest of the house. I'm too chicken to wallpaper, so I'd suggest painting the walls a warm white that works with the floor and vanity. I hate clutter, so if it were me, I'd find a trash bin that could get tucked next to the toilet, and move some of those things off vanity (maybe move the potted plant to the top of the toilet tank and lose the other two things?) It's a small room, so I'd try to limit the number of competing metal finishes. Not sure if I'm seeing this right, but it looks like a different finish for the faucet, TP holder, cabinet pulls, mirror frame, etc.

Maybe paint walls a lighter color. That may make the vanity look better. The mirror, from what I can see, looks nice. As mentioned, a nice rug. Artwork and move the waste bin under the sink. The art work on that one wall looks a little lonely... Maybe move to over the toilet and add something else or shelves. It is a nice powder room...

Agree, removing the valance, painting a lighter color of white or off white would certainly brighten it up. Garbage under the sink.

Moving the toilet tissue holder to the end of the vanity where it won't show would make that wall less cluttered. I think the vanity and top look fine. What is your view out the window? Do you need to keep the blinds closed - could you do a half curtain?

in order of cost and effect 1. remove the valance and use just the blinds 2. you don't show your bath/shower. if you have a shower curtain the whole look of a room can be changed just by changing it 3. change the wall color. a lighter color pulled from your vanity top as a neutral. you can easily bring in any color you want in towels and accessories. or a bath is also and ideal place to go bold its small and you can easily repaint if you want a change 4. the flooring on my screen looks pink and doesn't go well with the vanity top. both are more expensive things to change. I would decide which you like better and work with it and replace the other . for me it would be the flooring

I would remove the valance and use the blinds alone. Choose a lighter, softer color for the walls, and find a good quality patterned rug that coordinates with the new wall color to use in front of the sink. The vanity, countertop, and mirror are fine.
