I am are looking for a diverter to operate 2 shower heads, regular shower head and waterfall shower head that is mounted from the ceiling. I would like to have the option to use either shower head or both shower heads at the same time. Is there a diverter that you can do this with?

Is this a tube or a shower stall? Any brand names or models for this water fall, sounds like a rain shower.

There is number of diverter valves you can use. Most common are made by Delta, Grohe, HansGrohe, Kohler and more. I am not sure about valve that allows both heads to run full force at the same time. This is usually accomplished by installing 2 separate volume control valves. Back to you. Milo

Milo, would you use 2 way diverter (if there is such a thing) or a 3 way diverter?

This is a walk in shower that a am currently roughing in so everything is open. There will be a rain shower head from the ceiling. I need to purchase everything for the shower yet.

I would suggest using two separate volume control valves and one 3/4 inch temperature control valve. In this setup(ive only installed moen) you supply the temp valve with 3/4 hot and cold, then off the top of the temp valve you supply each volume control valve with 3/4 via a tee. Then off the top of the volume valve you supply each shower head with 1/2. This way you will have enough volume to run both shower heads at once with great pressure, and the control to use either shower head separately. You could even add a third volume control and have a hand held shower or add some body sprays. Ive done quite a few of these setups with moen products and the homeowners have all had raving reviews on the systems. Just beware, the more you add, the more creative the plumbing will get to fit it all in the wall. Good luck and please let us know how it all works out.

Milo, would you use 2 way diverter (if there is such a thing) or a 3 way diverter?

You will need 3 way diverter for your situation ( 1 Inlet (mix h/c)) and 2 outlets ).

I am enclosing pic of shower we did recently. Left and Right sides are identical. They consists of Thermostatic valve and 3 way diverter ( 1 inlet from Thermostatic Valve, 1 stationary shower head and 1 hand-held), each side. Middle valve is regular thermostatic / volume control valve that operates Rain Shower head only. Incoming water pipes were: Cold water side 1 1/2" to each valve with 3/4" valve inlets. Hot water side was plumbed with 3/4" pipe all the way. Shower head risers were 3/4" as well. House pressure: 55 psi.

This is the proper way of installing such a system. This way, you can run all 5 shower heads full blast and still have adequate water pressure and flow. Make sure you hire experienced plumber for such installation. Don't try to cut corners. If you do, you will regret it every time you step into the shower.

Good luck with your project. Let me know how you did. Milo

That's a nice looking setup Milo. Good job.
