Tiling Over Existing Shower Pan

Hello,

I have a few questions about a bathroom shower remodel project? My experience level is intermediate.

The house is 30 years old, I remodeled 2 of the bathrooms already.

I am getting ready to remodel the final bathroom which has a shower stall the same size as a bath tub.

I am going to build a 33" partial tile & glass block wall (not going to the ceiling) as we no longer want shower doors. The entry to the shower will be around 26 inches or so.

My question is can I tile over the old existing shower pan?

Pan Condition: the old shower pan is in good sound shape, not squishy just dirty & stained. I was thinking I might tile right over that old shower pan. Just in case it may become squishy I was going to spray some foam underneath the pan to cover any unforseen problems that may arise in the future. I planned to attach the partial wall on top of the pan edge and to the studs in the wall.

Now if the answer is YES to all ..............

Will the mortor and tile hold on to that old pan or does it need to be treated with something or will I use cement board?

Just screwing in a new drain, will it reach? Yes? No? It looks like it will?

Any advice would be greatly appreciated.

Thanks,
Robin

I have overlayed a couple but not at at my expense. I had to save a hack.
To set the tile I used Mapei white unsanded thin set or (pre mix)but mixed wet. It will look or feel like flour and water. You need to determine if your drian will raise the depth of the tile you are adding. Sometimes they are tough to unscrew after they have aged a bit. I usually had to break out the area around the drain so I could get a good grip on it, then I mud it back.
Is it the desired way, I think not. Is it the easiest, I think so.
Hope this is what your looking for .

Hi Robin, welcome. If you are redoing the shower, why not go all out and get rid of the pan and do a mud base. You can find info here.

Thanks for the input

Thanks for the input!

Question? Think the Mapei is the only way to go?

Regular mortar won't work or?

Again thank you!

As for doing a mud pan, I've been thinking about it. Feel a bit intimidated and was wanting a short cut because that old pan is in good shape but badly stained. The mud is not out as of yet but was trying to get some input on the tiling over the old idea.

Welcome Robin!

I might be reading this wrong, but I think Robin has a hollow fiberglass shower pan. And Scott thinks it's a mud pan.

Robin, please give me a clarification if you would. Thanks.

All bets are off. You can't tile over it.

really?

OK

so all bets are off?

is there a reason?

I talked to a plumber 30 years experience on Kasamba and
he said it would work, of course you know I have to have more
than 3 people's advice that's why I'm here.

Now I don't know very much BUT.........
I know you must have a reason for saying that?

Could you please explain? I really need to hear it.

Thanks,
Robin

There are several reasons. First, a fiberglass pan flexes too much. I know you said it feels sturdy, but that's just not going to cut it. Second, there's nothing to really adhere the tiles with that will last very long. Last, the drain isnt the type that you can unscrew to the proper height, as if it were a regular mudbed type drain.

Sorry, you either have to replace with another shiny white fiberglass pan, or build yourself a mudbed. They've talked many a DIY'er through it 'round here, Im sure with some bathroom experience behind you, you'll be able to do it too....

Oh, try not to listen to plumbers when it comes to tile work... (and Home Cheapo employees too )
