I think just changing the walls, ceiling, fan housing, and toilet seat cover to white would make a whale of a difference. You could also also swap the heat register cover for one that matched the floor tile.

I’d also remove the glass doors over the tub and replace with a curved rod and shower curtain.

What color are the tiles?

I couldn’t take the wallpaper anymore so I took that down! The tiles are a dark beige/ tan.

Here’s me ripping off the wallpaper but it gives a better look at the color of the tile.

Shades of blue look lovely with that color. My preference is for navy blue...gray works, strangely enough.

Mossy green?

I'm guessing you don't want to paper again...

Sherwin WIlliams Sea Salt is a good color for a beachy vibe...

Lucky you with that wallpaper...sometimes it can be a beast to remove...

I can’t even tell you how jealous I am of how cleanly your wallpaper came off. We just went did battle with two rooms where it tore off in tiny 1/2 inch chunks much of the time.

Anyway, I agree that changing out the toilet seat for a white one and getting rid of the glass/brass shower doors would make a huge difference. Would you prefer color or neutral walls? I could easily imagine an off-white paint color with some bold art and bath mats. It looks like the tile is in excellent condition, so kudos for keeping it.

Take off the door and make it to just tube. Place a curtain rod. Ripe off wall paper and paint gravy , change toilet cover , change towel handle to metallic.

Lucky for you that the paper came down so easily. As others commented, take out glass enclosure to tub. Replace toilet seat. Paint and add some nice fluffy towels. Little changes making a huge impact

I couldn’t believe how easy the wallpaper came down either! I’d read horror stories about taking down wallpaper! I’m hoping to make it brighter as there’s no natural light in this bathroom.

have you looked at retro renovations website for working with older tiled bathrooms? they have great ideas. I'd say, replace doors (not hard to remove) w a shower curtain. i'd also consider choosing a fabulous wallpaper that you do like for the walls, or a great paint color. be bold!!! it's the way to go with these vintage bathrooms (speaking from experience, mine is cream and red)

You may have holes in tile once you take out glass doors. My sister did and the replaced it will a more modern glass door, only metal frame is at walls, doors are fully glass, that also covered the holes left behind. You can still use a shower curtain for looks and take inspiration from shower curtain for paint colors.

wow...you're half way there just pulling back that wall paper. I 2nd using a shower curtain in front of the showers doors...as least until you decide on a more permanent fix. Can you post a picture with all the wall paper down??

I suggest taking down the wall tile. Its size is too close to the size of the floor tiles.

The room looks better already!

My master bath currently has bone colored tiles with white floor tiles and white tub, toilet, vanities... when I moved here the walls were painted spring green with gold fixtures everywhere and it made me nauseous! The bone colored tile looked so dirty! We got rid of the shiny brass fixtures (they were corroded anyways) and replaced them with chrome, and I painted the walls a light blue with a lot of grey in the blue to tone it down. It made the bone colored tile look fabulous! We still need to gut the entire bathroom (shower is unusable and leaks into our family room below, we’ve tried three times to repair it without gutting it because we’ve had to do so many other projects before this bathroom) but at least the bathroom no longer LOOKS bad.

looks great!! removing the doors will leave small holes in tile and possibly some marks on tub (mine were minimal after some scraping with a putty knife and I'm probably the only person who sees them). You can caulk holes and the shower curtain hides the rest. I would consider a bold third color to bring into the mix.

what does the vanity/sink/mirror area look like?

Here’s a picture of the sink area before I took down the wallpaper!

Honestly, it's all in very good shape...

You just have to choose a color. Personally I prefer the shower doors as removing them, you will have holes (and your tile is white, so you would have to get a caulk that is a closer color)...it really depends on what shape the metal parts are (they can get pitted).

Give the floor grout a good bleachy clean and then put a sealer on it to keep it cleaner.

I would want shelves somewhere...or a cabinet above the toilet...but that's easy enough.
