We have a Hansgrohe Aktiva hand shower/slide bar. Had to take out the water restrictor because it causes the hose to burst apart from the (whatever the technical name is) round wall connector. We went through five hoses before giving up and popping the restrictor out. No problems since. I don't like doing this because: 1) we're serious about saving water in CA; our drought is on its third year and this is the fourth serious drought I've lived through since moving here. So it's EXTREMELY wasteful. We take short showers and are putting in a gray water system. 2) I frankly consider the Waterpik in the other bathroom to be a better showerhead, saves water without the overpressure problem, and costs 1/10th the price. Our last one was still going strong after 17 yrs when we left in our last apartment. It is, however, not as pretty as the Hansgrohe.

Just a word of warning on Moen slider bar fixtures...their chrome fixtures the pieces that hold the bar in place are plastic. I made the huge mistake in building of picking out a book and not putting my eyes and hands on the actual fixtures. Not until they were installed and we were moving in (we built from 1300 miles away) that we discovered they were plastic. There was really nothing we could do at that point without changing all the other fixtures in that bathroom, so we sucked it up and lived with it. That is until about two weeks ago in one of the showers the plastic on the bottom failed and the bar fell out of the sleeve! I called Moen and even though it's been over 2 years since purchase they sent a complete replacement. They have completely redesigned the shower bar and while the pieces are still plastic the design is much better and much more sturdy. They have great customer service, their phone system is great. If a CS rep is unavailable you record your number and they give you a time frame in which they will call you back. It's so much better than being on hold forever. Probably way more info than you wanted, but wanted you to be aware.

You've gotten some good info. I'm not sure if you want the hand held in place of the fixed wall shower head, or in addition to it. So I'll try to describe both. Part One, you just want the handheld on a sliding bar: If you just want the hand held and don't want the shower head that came with the D500058, then you need the Danze D469058 wall outlet. You'll use a short brass nipple to attach the wall outlet to the copper fitting inside the wall. The same type of copper fitting that a typical shower arm would get threaded on to. The nipples are only $1-$2 at any box store. You can buy several of differing lengths (1-1/2" to 2" generally), use the one that fits, and return the others. The length needed depends on how deep the drop-ear fitting is buried in the wall plus how thick your tile backer board and tile are. Brass nipple: 1/2" Drop-ear fitting: Your copper tubing get soldered into the "smooth" opening, the shower arm of the shower head or your brass nipple for the wall outlet get threaded into the threaded end. Use teflon tape of teflon pipe dope on all threaded joints. When you plumb it, have one port from your supply valve go to the tub spout, the other port that would normally feed the shower head will instead be plumbed to the Danze wall outlet. Screw one end of the handheld hose to the wall outlet. Attach the other end of the hose to the handheld. Mount the wall bar on the wall. Attach the handheld to the wall bar. Part two, you want the handheld in addition to the fixed shower head on the wall: You'll still need the Danze D469058 wall outlet. You'll also need a diverter valve. I took a quick look at Danze's offering and only see a 4-port diverter valve. All you actually need is a 3-port valve, but a 4-port can still work and allows you to stay in the Danze family. The Danze 4-port is actually designed to have one if its ports capped if you don't need all three outlet ports, the cap is even supplied with the valve, so they make it easy. If you want to go with a 3-port diverter, pick anything you like. I'll stick with Danze for the description: You'll need the Danze D130000BT diverter valve and the Danze D560858T Parma trim kit to go with it. The installation instructions that come with the diverter valve are pretty self explanatory. However... Your hot and cold water supplies will feed the valve that came with the 500058 kit. That valve has two outlet port. One will go to the tub spout, the other now goes to the inlet of the diverter valve. You'll use the supplied cap to cap one of the three outlet ports on the diverter. One of the uncapped ports will go to the fixed shower head. The other port will go to the Danze wall outlet which in turn will feed the handheld. The Danze 4-port diverter affords you the opportunity to feed just the handheld, just the fixed shower head, or both simultaneously.

Depends how you plan to use the hand shower. We have two. The one in our basement guest bath is on a long (40") bar, and we positioned it so that it would be a good head height for my 5 foot tall daughter, and we placed the fixed shower head high enough for my 6 foot son. We used this bath for 4 years while waiting to reno our Master BR (sigh). I liked to have the hand shower set at a height to hit my lower back, also low enough to grab easily while cleaning shower, shaving legs, etc. In our Master BR (finally done), I have the bar set much lower, as it will ONLY be used for lower back, for shaving legs, etc. I absolutely love standing under rain shower setting on fixed and having hard massage setting on hand held aimed at my lower back.
