 Are Tub/Shower Valves Interchangeable?
Author: cakins (MO)

Shopping online for tub/shower faucets and see that the valves are sometimes (always?) separate. Can one brand of valve be used with someone else's handles/spouts? Just curious, cause I found a faucet I like on Price Pfister's website, but they don't even list their own valves! Could I use a different brand valve instead?

now that is just a persona; opinion. there is nothing wrong with price phister. in fact i prefer them.

now what do you mean they dont list their own valves? i am thinking you mean they just show the trim. if that is what you mean then dont worry about the valve. in the description it should tell all you need to know about the valve like if it is pressure balancing ect..

and to answear your question. no most trim is faucet/maufacture specific

What I mean about PP not listing their own valves is that they say a valve is required, but look for "valves" on their website and they aren't there. I had to really search to find the valves online. Even some online retailers of their faucets don't offer the valves, yet their descriptions say a valve is required. Why would they sell the trim and not the valve?

Also - re: "buy Moen or Delta" I wouldn't mind except their ultra modern stylings are out of my league unlike the Contempra line of Price Pfister. The Moens or Deltas in my price range are boring to me.

You cannot interchange different manufacturer's handles and spouts. In fact sometimes you cannot even interchange the same manufacturer's trim between their own models.

I think you are mistaken about the valves not being available. Give a web site for one of those companies. If they do have the trim and not the valves, then it is a problem with the company, not Price Pfister.

First, you absolutely CANNOT mix manufacturers on trim and rough-in valves. In fact, even within one manufacturer, they have many valves and the trims are not interchangeable.

Shower sets are not always sold as separate trim and rough. In hardware stores and home centers they are almost always sold aa a complete set. Even on a manuf. website, you will often see a complete set. If they are showing trim and rough separate, the catalog will be very clear what trim needs what rough.

Don't understand, a faucet is a valve. A lot of times the trim will work with a different valve, but it takes a lot of research to find some that is compatible

There are at least a dozen different splined broach sizes, not to mention un-splined brass stems with a flat side, not to mention varieties of plastic stems too numerous to mention. Now, we have not even mentioned the methods used to attach the escutcheons to the valve bodies, nor the necessary depth of handle broach and escutcheon.

Since it is not advisable to use the word NEVER when dealing with plumbing issues, I will just say if you are looking for a trim set for Brand "abc" and are looking at any other brand, it is probably a fools mission. Can you give any example of a trim that will fit a different brand? Don't even go there with so-called "universal fit" trims. That is not a professional approach, and judged by most to be unsatisfactory.

????? "A lot of times"? I think it is more a case of once in a great while, and even then it may take parts from two or three different manufacturers to make it work.

Most of the time different trim from the same manufacturer won't even work! You have to figure the base valve then what fits on that I wouldn't even dream of wasting my time trying to mix and match across different manufacturers.

It might be something a DIYer might try over several weeks of spare time... It least until the whole family gets a bad case of BO!

The thing is too that once a fixture is "bastardised" that it becomes even more difficult to figure out what it is and what is wrong with it. I had a recent job where a moen shower valve wouldn't shut off I was already to change out the cartridge when I realized that it would shut off if I pushed it in a little more. The faucet was supposed to have a #16090 escutchen, #10089 tube, & a #96797 knob. Someone had installed a trim kit for the moentrol valve fortunately the customer had another valve that had the right trim and I swapped and compared parts, verified what was needed got the right parts and completed the job. Without that other fixture it would have been next to impossible to figure out what they had done. It had worked because on "O" ring had been used as a spacer to make it go in a little more, but when the "O" ring broke it was over.

What I'm saying is there is only one way to do the job... THE RIGHT WAY!
