Moen 8342 Reviews

Rated 5 out of 5 by from Solid shower system This dual shower system with showerhead and hand shower was purchased for a master bath remodel job. The new shower faucet came with everything needed including valve, diverter, wand, hose, and wall bar. Price was very reasonable and the chrome finish looks good. Commercial quality. Looks and works great!

Rated 3 out of 5 by from Good Deal but Shower Heads need Replacement We have purchased two of these and they are great. The only complaint is that we did not like the shower heads. Perhaps because of the water saver restricter in the shower head, the showers emitted a high pitched screech during the whole shower. We went and bought two Waterpik shower heads and they work great. Problem solved.

Rated 3 out of 5 by from Difficult Install It is in and the shower fixture works fine now, but the temperature valve inside does not match the picture guide outside. Also, you better be a good welder when you make this, my father assembled the plumbing and it has about 20 welded joints. I was not his favorite person the 8 hour day he spent putting this shower fixture together. The instructions were apparently unhelpful and he had to make 2 separate phone calls to Moen support as a few things had changed between the printing of the instructions in the box and how it is actually currently being done. It was a very frustrating experience. Now that it's installed though I have no complaints, it works well and looks nice.

Rated 4 out of 5 by from Very Good Shower System Just had this shower system installed in our master bath remodel. After having a leak repaired (had to tear out tile etc) all works as hoped except for a few concerns. There are only two settings on the main shower head and only one on the hand held. Thought that for $350+ there would be more choices of water delivery system. All in all it a very good shower.

Rated 5 out of 5 by from Works great The plumber said it was very easy to install. It gives great water pressure. I looked forever to find an affordable shower head combo with the slide arm for the hand held shower. With this, whin my mother takes a shower, I just have to put a chair in the shower and she can sit to wash with both hands free. Thank you.

Loading nanoRep

Does this system include the wall elbow?

The Moen 8342 includes the A725 wall elbow.

What is a CC connection?

CC connection means it is a copper-to-copper or a "sweat" connection.

Does the Moen 8342 have a scald guard?

Yes, the Moen 8342 does have a scald guard.

Is this pressure balanced or thermostatic?

The Moen 8342 is pressure balanced but not thermostatic.

Can I replace the Moen 8342 shower arm with a different shower arm?

Yes, as long as the new shower arm has a 1/2" connection.

Does the hand shower have different spray patterns?

No, the hand shower is a single function hand shower.

Can the hand shower and shower head be used simultaneously?

As long as the transfer (diverter) valve you purchase can support a shared function you will be able to use the hand shower and shower head at the same time.

Does the Moen 8342 have volume control?

This unit does not have volume control - when you turn it it will turn on full force and you rotate the handle for temperature.

Does the hand shower have a pause feature?

The Moen 8342 is does not have a pause function on the handshower.

Can a tub spout be added to this system?

The diverter on the Moen 8342 does have an unused port and could be used for a tub spout.

Is there a version of this with a tub spout?

The Moen 8341 includes a tub spout in the package.

Is a volume control required to operate this?

The Moen 8342 does not require the use of a volume control.

Are any other items required in order to install this system?

Moen put together a great solution for a shower combination. This is an all inclusive system.

Can you add body sprays to this system?

The Moen 8342 comes with a diverter valve that has an unused port which could be configured for a body spray installation if need be.

If I want to use the third outlet to connect a tub filler spout, which ones would be compatible?

The Moen 3804 would be an appropriate non-diverter tub spout to add to your system. The diverter that is part of this system already is a three function, so all you would have to do is connect the tub spout to the third outlet.

Can the hand shower be switched out to a different model?

Yes, any Moen hand shower would work.

In order to control water flow and temperature with the Moen 8242, which Moen rough-in valve must be used?

The Moen 8342 includes all the required parts to control the temperature and flow of water.

Can the wall elbow, on the Moen 8342 Shower System, be mounted lower rather than shown? Can I mount the hand sprayer other than to the bar?

The Moen 8342 Shower System wall supply elbow can be installed at your preferred height. A handheld holder mount  can be installed on the wall instead of using this slide bar that comes with the 8342.

How long is the slide bar and can it be used as a grab bar?


The slide bar for the Moen 8342 is 28-1/2" long. We do not recommend using this as a grab bar. Grab bars generally have steadier and more reliable connections to the wall where as slide bars are made for the amount of weight for a hand shower and that is all.
