Tips on hiding this tile?

Check in a tile store to try to match the tile. Then you can cut and replace the broken one. (I'm assuming the tape and cardboard is hiding a broken tile) Make sure it's OK with the landlord to do the repair.

After checking with the landlord I would find a tile that is almost a match. It doesn't have to be perfect because an almost match will look better than the cardboard patch.

Could your landlord fix it by having a tubs surround installed?

I would check with the landlord to see if you can replace those as well as a couple in the same spot on the other end of the tub with an accent tile that way it won't look like a patch job. Another option would be replace the apron on the front.

Hi Aisa, go to the home improvement store and buy some peel and stick vinyl tiles, you can redo the entire side to look good, and they come off when you move out if need be. Just make sure it's clean and dry, then apply right over the existing tiles including the "repaired one" good luck! 🙂

Have you explained this to your land lord and asked if they are going to fix this? Don't do any work without first clearing it with the owner.

replace the broken tile with something similar in color but same size and ask if you can paint the tiles so they all match

Lots of great solutions. What ever you do make sure you get permission from the landlord in writing. You don't want to lose your security deposit if you ever move. Take before and after photos too.

It should be an easy match, a very common tile at diy stores. Get the permission of your landlord, of course, in writing so no surprises at the end of your lease. And take photos to cover yourself.

maybe you can buy a shower curtain and place it in that spot

Boy, unhelpful landlords are just so frustrating. Since (s)he is already this way, be sure to get any and all permission for anything you do, in writing, as it sounds like they could be problematic when you move. It does look like a pretty common tile, so check all the stores near you for a replacement. Keep the receipt and deduct it from your rent.

You may have to check it with the landlord. Or you can simply put a shower curtain for this.

Put contact paper over it or wall paper on it

Habitat for Humanity carries older tiles. Check there first. If not make or get an extra long shower curtain.

i would ask landlord to replace whole side of it or simply use epoxy paint and change its color
