Actually, I like the black trim and your tile. Don't paint it. You might try updating the faucets and the mirror (unseen in this photo you posted). Here is one that is very similar to your bath but it is green tile. Look at how updated it looks with just a different mirror, lighting and faucets. Accentuate what you have ....

You've done good with what you have.

I would only replace the floor. How about a hex tile? Doesn't have to have the black accents. Just white would freshen it up nicely. I like the black/pink and I think the buyers will too!

If your bathroom is in good condition and does not need to be replaced, don't bother. The room fits the age and style of the home and is comparable with others in your neighborhood. I'm a vintage home lover and I would be thoroughly disgusted if I knew that you renovated such an interesting, authentic bathroom to try to sell the house. I would rather see an original 1937 bathroom in great shape than a new bathroom which will be dated in another 5-10 years.

Fix any leaks, missing grout, cracked plaster, sticking doors, and peeling paint and give everything a thorough cleaning.

I agree with Linda. It's just fine. If you have already done what she says, spend your time and attention on the front landscaping, the kitchen, and the master bathroom. I assume the house is newly painted inside and out and it is already clean as a whistle everywhere.

HI -- The only tiles that were added after the fact are the ones in the bath tub area above the first black trim tiles . Those were probably added in the 70's or 80's . If you can remove those and the very top black tile. Then paint the rest of the bathroom a bright white . Then only have white for all the accessories like the shower curtain ,towels and bath matt and so on. Just have the black tiles and the picture frame as the only black in the room. If the room is in good shape , then leave it . If I was looking to buy , I would not want the original tiles painted or the floor changed . As long as the room is clean and bright and smells good and has lots of white ,-- it should sell . I wouldn't put a lot of time and money into big changes if your selling. The new owners will have their own ideas for the room.

I love the bathroom! It fits the age of the house. As long as it is clean and in working order, I wouldn't touch anything. Maybe the shiny things - the mirror, faucets, towel rails. Otherwise it's great how it is.

It would be criminal to paint or replace those tiles.

groveraxle, that's great! My mom had the 70's version: pink toilet, bathtub and sink, brown wood panelling on the walls.

Darling! Vintage is in. Steam clean the tile and brighten up with highest watt bulbs you can. Use all white towels, shower curtain and accessories to make it seem as light/large clutter free as possible (no rug, no picture, just towels and shower curtain, I might even remove those too) and the shiny tile will be the star. Seriously it is cute.

I know these are not the colors of your room but they show a sparkling clean vintage tile bath with nothing in it and it looks like a place you would want to take a shower, and feels bigger without the accessories. Bake pumpkin bread or spice cake before a showing and you will get offers! Good luck.

in my idea it can be cheap if you just change Bathtub to a small stand shower cabin.
by doing this you would have more space and your bathroom have a good view,
it would be better if put high quality pic under your window that pic should show jungle our a corn farm. it can be fantastic isn't it? something like This :

My take on it: your walls look pale lemon and contrast with the white shower curtain. This may be the camera. If not, just paint the walls a warm white and sell. The new owners are going to do what they do with it anyway.Perhaps play up its Art Deco theme a bit more. Add a roman blind instead of the venetian blinds, more polished chrome accessories, and even some aubrey beardsley ( http://www.wikipaintings.org/en/aubrey-beardsley/the-black-cape-1894) framed prints in black frames. Finally, a lot of sins can be covered with an extra large black bath mat.

That floor IS pretty bossy. But a large bath mat wouldn't hurt. Like the advice of clean and sparkling. Would hate to see the desirable, authentic vintage disrupted. (Don't like the black towels.) I hate everything the previous owners of my house had the contractor do to 'update'....stuck unless I update my husband! ;/

Could you do some peel and stick white tiles over the current flooring. Like the room also.

Thank you all so much for your thoughts and ideas. I appreciate it more than you know! The mirror and light fixtures are not shown, but I'm going to update those and paint the walls white. I'm glad to hear that the tile can stay. I just wish more people appreciated these older bathrooms. I do like the idea of possibly doing something with the floors as well.

I would remove all the black items (towel, rug, curtain and picture). White items will give you a simple look that will play up the rest of the room. Make sure your grout is also clean otherwise redo.

Nothing seriously wrong with that bathroom if you ask me. Like many of the folks who've commented, I'm into the pink tile w/ black trim. I have a tuxedo shirt that I never wear kinda like that. It's not that it doesn't look good, it just never suits the occasion. It reminds me of my grandmothers place. She drove 85 miles an hour on back roads and would take all your money playing poker while she told stories about bootleggers. But I digress. If you're bored and just aching to do something, take a look at the mirror and see if it makes the same sort of kitschy statement as the rest of the room. Disagree with the white towels comment, stick with the pink and black unapologetically.

What a great grandma! Agreed, go with vintage look.

honeycomb mosaic floor tile in white with border of black that forms concentric ring just inside of outer perimeter.

You don't know the buyer will be. Maybe they'll knock it down or maybe its charm will make them smile. Stay true to the house. Clean it up and let its real vintage face shine through.
