Tub Spout Sealing


Rather than silicone around a tub spout, or shower head outlet escutcheon, is there anything wrong with filling in the gap between the stub out pipe and the tile hole with silicone? If it's filled in completely, it seems that no water would get into the wall, maybe some behind the spout or shower head escutcheon, but it runs out the bottom anyhow. It saves from the eyesore and hassle of caulking on the outside of those parts. Thanks a lot.

Re: Tub Spout Sealing


That's a good idea. Will the putty harden and shrink and leak over time? If I did go with silicone, is that a good or bad idea? Thanks.

Re: Tub Spout Sealing


I'm hoping Mark was being sarcastic. Silicone is fine. Though if you need it around the showerhead, something is seriously wrong.

Re: Tub Spout Sealing


Probably don't really need it around the shower head, you're right. But around the tub spout would be necessary. I think the only problem with plumber's putty is that if it hardened and started to leak you wouldn't know until it's too late. The problem with silicone I was thinking is that it would be damn tough to remove it later, but it probably would seal good. Was also wondering if the silicone would corrode the copper pipe. I HATE ugly silicone around chrome and ceramic tile, which is why I was wondering about this whole thing.

Various modern waterproofing systems seal the pipes behind the tile.

Re: Tub Spout Sealing


Many of the tub spouts have a foam gasket. Perhaps dress the gasket if worn

Behind the spout? I've packed that hole with putty on many occasion. Same goes for some valves behind the escutcheons. Who wants to deal with silicone on any future service?

Re: Tub Spout Sealing


OP here. Thanks for the tips everyone. Tom above suggested that some spouts have a foam gasket. Well, I ended finding a 3 1/2 inch trim plate with included gasket that will fit behind the spout. I have not installed it yet but will report back.

Re: Tub Spout Sealing


There shouldnt be any water getting behind the shower head cover all the water is heading down.
As for the mixer valve, on occasion when we have been called in to fix a leak we do a horse shoe of silicone behind the escutchceon.
No plumbers putty

Is there a gap between spout and wall? If you happen to have a single handle shower valve, maybe your trim plate screws are too tight which will push the spout pipe out of the wall. If so, loosen them up.

Re: Tub Spout Sealing


OP here. Just to be clear. I am talking here about a tub spout here. Just to remind everyone why I posted, I would like to avoid the ugly mess of siliconing around the tub spout where it meets the tiled wall. I know there are lots of experts that say just run a bead of silicone, and more power to them. The gasketed trim plate link that I showed above simply seals to the tile with a built in gasket, then the spout installs as usual outboard of that. It works like the built in gasket behind many single handle faucet trim rings.

Re: Tub Spout Sealing


Okay, I finally tried the gasketed plate. Unfortunately, the pipe was too short to allow the extra half inch or so that the plate took up. Still looks like a good idea. Will bite the bullet and silicone like everyone else. Will try to do it as neatly as I can, although silicone gets everywhere when I'm around it. And the more I play with it, the worse it gets...

No, not everyone uses silicone.

Re: Tub Spout Sealing


If the stub out is not sweated on you can get a shorter brass nipple to bring the spout tighter to the wall.
