Adding a hand shower?

I've installed our new tub in the new alcove opening framed on new floors that are sistered with new LVL joists that are also supported by a new LVL beam. It's been a LOT of work just to get to this point. Nevermind moving a window location and installing a new window in the bathroom. I'm working on the DWV system now, and should have it finished tonight. I would like to start on the supply plumbing tomorrow. A bit backwards, I know. But it was easiest to locate DWV stuff etc w/ the tub already in place.

Anyway, we bought a Moen Monticello single handle tub faucet, valve and showerhead. My wife would also like to add a handshower for washing the dog, etc. I would still like to keep the normal showerhead for everyday use. I would like to be able to switch between the normal showerhead and the hand shower. The ability to have both on at once would be nice as well, but not mandatory. How do I plumb this? I have no experience w/ handshower fittings, diverters, etc.

Anyone done this? Pics? Suggestions on how to go between the showerheads?

Be sure it is OK to install a handheld shower on that faucet. I've done it with a three handle, but it is almost impossible to do what you want with a single handle design. There is no diverter valve, the button pushes the water up to the head. You can put a diverter valve on the arm up high, but that makes it hard to wash a dog with the handheld, it needs to be down lower. We did a shower once, but installed a second faucet just for the dog wash.

Well, they have 5 and 6 foot "cords, right?" If I put the diverter above the faucet, I would think it would be enough to reach the dog with the spray.

Alsons has several hoses that are 84" long... See this link!

They also have this valve that attaches to the shower arm that selects the showerhead, the handheld or, both... See this link!

Redwood, thank you! Seems that the arm-mounted diverter would be the easiest, cleanest way to go. I like that it's so easy to remove, too.

Your welcome, I thought you would like it!

valve

I have never seen a valve like that which permits the use of both devices at the same time.

They come both ways.

And, again, I don't NEED both at once. It would be nice, but not mandatory.
