    Has anyone seen or installed the new Moen tub/shower rough in valves? They look a lot like a Delta Universal valve..

    Can't tell from the instructions whether they have mounting hardware like the R10000.

    Note: For thick wall, valve is mounted to a brace.
    Plaster ground is simply used for setting depth and hole size.
    Important: For thick wall: If hole is < 3", remove plaster ground before installing wall.

    Thick wall installation: (Most installations) The thick wall installation method is used when the tub/shower wall is greater than ¼ inches thick. Thick walls are usually built up with materials such as cement board, drywall, tile etc. The plaster ground will aid with alignment and can remain attached to the valve until the valve has been positioned and secured.

    1. Drill a 4-1/4 inch hole in the wall (the same size as the plaster ground) in the location shown in the installation schematic. This hole will help support the valve during installation and allow access for future servicing if necessary.

    2. Position the plaster ground in the hole so that its printed face is flush with the finished wall. This will ensure that the valve will be at the proper height to accept the trim.

    3. Mechanically secure the valve to the wall frame members by the use of straps (not included) or attaching the valve mounting holes to a cross member behind the valve thru mounting tabs on the valve.

    4. Attach the water connections to the valve.

    5. When the trim is available, remove the plaster ground.

    straps not included.. blech. already don't like it. ***OK.. I watched a video that shows that they have mounting bracket built in*** However their valves/trim just became a million times more unnecessarily complicated! Jeeez. And now these are Lift for volume and Rotate for temperature adjustment. The trim is hansgrohe complicated now..

    At least their trim packages wont look like crap when the handle is far out from the wall anymore.

    Will be interesting to see what the cartridges look like. They've been almost the same since that push pull style was invented in the 40's? ***cartridge looks like a cross between the american standard front and the Kohler k8304 back end** oddly reversable

    The mixing valve and the transfer valve finally line up directly.. yay! no more weird offsets.

    Will reserve final judgement til after an installation or 10

    We installed our first one. Our plumber didn't read the instructions of course and dropped the cartridge out of its protective sleeve and then had to figure out how it went back together. Otherwise no complaints from the field on 1 installation.
