Whether vintage is "very in" or not is immaterial if it grates on her.

New countertops and sinks. Paint the cabinets. Paint the trim. Do NOT paint the floor; that's just a hillbilly solution. And in a wet/damp environment or with bath mats with rubber backing it will peel faster than a stripper on a busy night.

@greenDesigns yes was thinking white on walls ! Accent color black ?

@tatts yes was hesitant about the floors . Plus I have 3 kids and a dog !

@tatts what do you think of wall color should I go white ?

I’d remove the curtain, remove soft toilet seat cover, paint trim, mirror frame and vanity white, pick a light color for the walls (in the white/neutral family, but different from trim), maybe change the blinds, get a prettier shower curtain or a nice fabric one in white, and get a pretty woven rug with colors such as white, oatmeal, light blue and orange in it (or other 3rd color you like such as green or navy). also put something with your chosen 3rd color on the countertop such as a tray or other functional or decorative object.

I like your light blue tile, but it’s your home. When you have saved up enough for your full remodel, you can address whether or not you want to demo the tile. I’ve heard people on here recommend looking at a site that is dedicated to retro renovations, but I can’t remember the exact name of the site.

Benjamin Moore's Super White.

Remove valence and get a new shower curtain. Paint walls white (slightly different shade than painted white trim). Ain’t vanity. Replace bath mat. Remove toilet seat cover.
That all shouldn’t be too costly. If you can find a good deal on new countertop and undermount sinks, do that. Otherwise wait u til you fully remodel. I think all this will bake you like the blue tiles better (I actually like them and the floor, and I’m not a big vintage fan!)

I am not a fan of white walls. I think I'd paint the walls, the trim and cabinets a shade darker than the tiles, and definitely replace the faucets. Until you do your major reno, keep the counter top. And do replace the fabric stuff, maybe lighter in color than the blue tiles, and have them match. (I had a small powder room in one of my homes...it was small!...and I painted the walls a dark wine color...looked wonderful...and did not make the room look smaller). Or, if the blue is too much, wallpaper.. There's not much wall space, wallpaper is easy to put up (just make sure you size your walls well for easy take-down) and there's many nice patterns

I really like the color of the tile...it's showing up as a pastel greenish blue on my monitor. Almost a neutral color.

I would replace the toilet with a white one. And replace the vanity top (going to a single white sink). Maybe paint the vanity or replace if you can find one on the cheap.

From there you can go a number of directions. Play it safe with white, white paint. Go w/ coastal/ spa colors. Or an English cottage garden look. Or even more earthy with a less than white/ white paint and a Southwest paint palette.

I love your bathroom. I would probably paint the cabinets white. White would be fine on the walls. It looks to be in excellent condition and retro is very popular now. You are very lucky to have all the original, and have it be in such pristine condition. A new shower curtain and call it done.

I recommend being brave. Go with dark background wallpaper navy blue or black with big scale print of flowers or tropical leaves. Your tile looks more blue than green on my monitor. I will find some inspiration photos for you. Bbl

Strip everything away, curtains, rugs anything you’ve added. Paint every wood surface bright white and paint the walls white. DON’T paint any flooring, tile or counters!!! Change out the hardware on the cabinets to chrome. Now add back a rug in either white or blue and add a white fabric shower curtain. Replace the blinds with faux wood white ones. Those can be purchased at Home Depot for $50 or less and they will cut them for you. They will give the window more presence than the mini blinds. Or if privacy in that window isn’t an issue (because when it’s pulled up the window is exposed) I would do a roman shade in a fabric that ties into blue and white. Now save save save for a Reno!

I also love all the tile! And it looks to be in great shape. It's the wood trim that I don't like.... New counter and mirror/medicine cabinet for sure.

Agree with much of what others have recommended...but I would also put in a new countertop. A prefab white quartz one would not be prohibitively expensive. I think with changing trim paint to white, wallpaper, the new counter, and new window covering and shower curtain the bath will be nice enough that you won’t feel the need for a gut Reno for a very long time.

Here is a powder room I helped transform. The owner had black fixtures and didn’t have budget to change. So we embraced the black and transformed the room. They love it. Just embrace that beautiful tile. Here are a few wallpapers to help give you direction. I am still hunting for a Posters green tile bath to show you to see how great embracing that tile can be.

Love the Banyan tree wallpaper!

Nice vintage bathroom! If it were mine, I would go with pink_peony's suggestions including white walls, and a pretty white or white and black shower curtain, If the wood vanity is in good shape, I wouldn't paint it. If the toilet seat doesn't match the blue toilet, matching seats are available. Color chips can be ordered from Bemis to find the correct color match. https://www.classic-colors.com/

Retro Renovation is an excellent website to search for ideas, especially under the "readers and their bathrooms" tab. https://retrorenovation.com/category/bathroom-categories/

Here is one that might be similar to your tile. https://retrorenovation.com/2016/10/10/midcentury-modern-blue-bathroom-remodel/

Soften the contrast and aim for a spa-like look. It will make the space feel larger. Black is too dark of a contrast, as it cuts the visual field and draws attention from the soft colored tile. Keep the colors and accents light.. Paint the wood cabinets and trim . Remove the shower curtain, window valance, fluffy seat cover and rug. Leave the floor alone for now, but consider one or two washable flat weave cotton "Chindi" rugs. example below

Can you sew and by sew I mean fold a fabric, thread a needle, make a knot on one end and go in/out through the fabric? Bed Bath Beyond sells a GIGI shower curtain and valance (shown below) in a fabric that resembles Capiz shells. It is difficult to find in white , but the fabric is available by the yard here: http://www.fabricempire.com/round-petal-taffeta-white-fabric-54-wide-sold-by-the-yard.aspx

Thank you to everyone who gave me some great ideas! I appreciate all the links and pictures! I’ll post a picture when we are all done ! ❤️

Love the tile especially the floor! Lighten up the walls, shower curtain and blinds.

Please no black. I echo others about white walls, wood mini blinds. If you can embrace the tile you will be amazed what the room could look like with just new counter, sinks and faucets, mirror and lights. Huge bang for your buck. Good luck!
