this little question will likely seem silly after i am done the install, but before i go ahead and do something silly: i have the plumbing and the stall for a standalone shower and just cut out the holes for the 2 faucets. I am having trouble understanding how i am to make these holes leak-proof. The plumbing has a flange, the actual faucet provides the outside threads for the faucet handle to attach to, but my mind is yelling for a rubber washer, or something that will seal it all up. I don't think silicone on the back flange (behind the shower stall wall) is correct because how would you ever reseal it after the first install if there were problems?

So from the back side, i have the plumbing with flange, then the wall of the shower, then the faucet nut with threads, then the purchase faucet assembly... but no rubber, no obvious way to seal it. What am i missing? thanks very kindly, drew..

after thinking about it a bit more, my thoughts are that i am supposed to silicone the larger chromed flange to the wall of the shower? but this won't prevent water from slipping in as that flange is definitely not super tight.. drew..

We seal faucet escutcheons from the inside of the shower. If tightening your escutcheon/flange does not secure it against movement, then you can install a separately purchased large washer to install on the faucet body side of the shower unit.

i just looked at a diagram of a bottom mount faucet and noted a lock nut and what appeared to be a washer under the nut. This is what i appear to be missing. Neither the new faucets, nor the faucet kit from Delta has them. The plumbing is original and perhaps the locknuts were part of that assembly, and i lost them in the deconstruct.

So, if i am correct, i will head out to the hardware store and buy a few locknuts and rubber washers and seal up that hole! Make sense? thanks kindly, this is an awesome resource! drew..

If you do need to buy nuts and solid washer for the back of the faucet then you may need to take the faucet with your or buy extra nuts. There are many diameters and thread per inch differences on nuts.

I presumed you have a 3 1/2" shower faucet that has a molded-in brass flange on the outside of the shower. On wide spread lavatory and whirlpool faucets we do have nuts and solid washers to adjust to allow for different thickness of the tub or lavatory. I've not seen them on a shower faucet but it may be possible.

I now understand that you have a two handle Delta shower faucet. We do not have back nut and washers on them. The faucets are mounted solid to the house framing and the escutcheon/flanges tighten down to a wall which does not flex. Your stand alone unit flexes. You may not have lost any parts because they were not there to begin with.

Try your nut and solid flat washer idea. Since you have a thin wall I think it could work. You may want to double nut. A rubber washer would go on the inside of the shower. We prevent leaks by sealing on the incoming water side.

ahh i am close to calling a plumber.. I just cannot find any nuts to fit. I may try another store later today, but this seems like the only route. If i just use the flange, and silicone it, my mind tells me that drips and body splash will easily run in the opening anyway.

I may have to go and buy a brand new fixture for behind the shower wall. Trying to match the old one seems to be at the heart of things. Trouble is, i already cut two 1 inch holes to match the current fixture. I may have to fill them somehow if i cannot find any fixture set to 3 3/8th" on center between the 2 faucets.

I may really eat it on this one √ú drew..

All you need is "something" to back-up the thin walled shower insert........

Usually the Cement Board or Green board wall covering is DIRECTLY behind the insert with the holes fitted close to the faucet body......You need a solid backing......

.....the escutcheon sandwiches the insert against the wall.......SO WHAT'S BEHIND YOUR INSERT ?

.......If there's a space lurking there I'd cut a piece of waterproof cementboard or PVC Trim stock and drill the faucet holes and fasten all to the wall with screws and caulk........

Darruu keep trying you are close to solving this. While finding the right nuts is a challenge you should be able to find flat washers that will fit over the faucet stem body. Instead of nuts how about small c clamps to hold the flat washers tight against the shower wall?

Doug he has a self standing shower that is not against a wall. However I do think your idea can work if darruu cut one or two boards that fit over the stems so that pressure could be applied against the faucet body, he would then have something for the escutcheon/flanges to be tightened against.

Calling a plumber may not be your best alternative. We need to fix things so that the repair will last. In this case it would probably mean a new faucet which you could probably do yourself. If you do call a plumber you should explain the situation in advance so that he will be able to be prepared.

However, like Doug I believe you can do this.

based on the confusion from everyone at my end, including hardware store folks, i just said "poo on it". I went and bought a single faucet moen setup that included the behind the wall hardware, pulled out my torch and yanked out the old stuff! I also used the plastic pipe and crimping tool to put together the hardware, so far no leaks, although it took forever because the cold feed would not stop dripping and the wetness keep the solder from taking (frustrating!)... anyways, no leaks, and i am building the blocking today. Wish me luck, drew..

Success. You've resolved your situation with an upgrade and excellent solution. I didn't think the round escutcheon would cover both 8" holes but whatever your characteristics you've solved it. Very good. I appreciate you letting us know about your solution.

If your single level faucet came with a plaster guard you can use it instead of blocking. The escutcheon bolts will tighten the shower wall to the plaster guard. Like a sandwich. The shower wall is the meat/cheese and the escutcheon and plater guards are the pieces of bread. This is how we often mount these faucets to fiberglass units.

Gotta stop and eat now.
