How can I make over these bathroom tiles without replacing them?

painting over the tile may not be the best idea since you can't make drastic changes - would the landlord object to the tile color changing? there are peel and stick tiles you can place over the top but it may damage the tile

If your landlord allows it, you could tile over the tile: https://m.youtube.com/watch?v=XRRYDEa-pDM

Or you could use tile stickers. I would check with the company to find out if they can be applied in a shower: https://myfamilythyme.com/updating-with-tile-stickers/

Yes you can paint a tub and tile and it’s very cost efficient. Rust-Oleum has a tub & tile kit that only costs $25. It comes in 3 colors (white, biscuit and almond). It’s received positive reviews from a ton of customers. I’ve done this on old tile and a powder blue tub and as far as I know it’s lasted years already.

I would absolutely get the apartment owners permission in writing before doing anything to the tile. It could backfire on you and replacing a tile wall could be a costly mistake plus they might ask you to move out.

I know it sounds counter productive, but if the problem is that you dont like the blue, add more blue! You could do a drastic update by adding navy/dark blue. for instance,a navy/white/tan paisley shower curtain, navy and white accents and navy towels. The light blue tile will now be an insignificant part of the decor. A wall paper would have the same effect if it were more proment that the tiles, Wallpaper is rater expensive for a temp rental though. You might find a fabric and put that on the walls. Anytime you are stuck with a color you don't like,add more of it in a different hue. Pink? add burgundy or a tan with pink undertones. Pea green? add dark or forest green. work with what you have!

You can color the grout a darker blue it will make a more dramatic blue and change the look.

I lived in an apartment that had ORANGE floor tile on the bathroom walls (YIKES!). With the landlord’s permission, I selected a white & “Delft” blue tile patterned CONTAC paper, and covered up that orange tile!! It looked great, and after 18 months, I moved out & the next renter enjoyed it for 2 more years!! The adhesive held-up well & was easy to clean!
