How to re-tile shower floor?

Yes, this shower is long overdue for some major restoration. Just based on the degree of deterioration that shows in the picture, I am wondering if the foundation under the tiles has already sustained water damage.

If so, all the old materials will first need to be completely removed, which will be a much larger job than simply re-applying new tiles. Keep in mind though, that going with a square drain cover (rather than round) will facilitate cutting of the tiles to fit.

Looks like U have a big problem likethe walls closest to the floor. Do the green tiles flex any or loose ? Size tile maybe 12x12 with some grit to prevent slipping. Or get an estimate.

Looks like the tiles are in a concrete subfloor. That's the way it was done back then. You would need to remove the floor tiles. If the wall tiles are loose remove the first course of wall tile. If they are stuck on good and just dirty clean them up. Let everything dry out. Use a self leveling concrete compound on the floor making sure it slopes down towards the drain. Use similar mosaic tiles in sheets on the floor. If you had to remove the wall tiles use the mosaic tiles on the wall.

I'm not sure that you can save that shower. It looks like water has been an issue for a while. Like what was suggested, check to make sure the wall behind the green tiles hasn't been damaged. If it has, you might have to redo the whole shower. If you have to replace wall tiles, get bigger tiles, that means less grout lines to have to clean. Check the pan and make sure that's still in good shape. There are a lot of tiles for the floor, just make sure that it does say that it can be used on shower floors. Shop online, there is a huge selection, You only need a small amount so it shouldn't be to expensive.

I'd get some contractors out for pricing (they can vary SO much you want at least 3 if you can). There's mold in there, so it looks like a total gut job. But it isn't very large, so unless you plan on moving pipes around, you may be very surprised at how much it will cost for a brand new shower.

Lendy, this is what I would do if that was my shower. These one piece floors are so easy to keep clean. Make sure you have a good foundation under it. By that I mean make sure you don't have any floor that has rotted from the water.

Lendy: the mold is troubling. This is a job for a professional... you need the drain floor re-leveled. Don't skimp! ...this is your health!

Scrap up all tile and concrete and grout clean very well you need some thin set down first then tile adhesive then lay tile let dry one day then grout then seal with silicone after completely dry

Hi Lendy, I would remove any loose tiles and fille the voids with a filler like drywall compound. Then i would put a treated plywood base over it, carefully cutting out the drain hole. Seal around the drain hole really well and prep to tile the new floor.
