Rainhead. The term "rainhead" has sort of been corrupted over the years. You really need to feel the output yourself and figure out what type you prefer. In my own shower I wanted a traditional rain head. Simple water droplets, so to speak. Mine is a 12" head, and I do consider that to be the smallest size for a decent rain shower, and without a doubt, that is my personal opinion. You want the head away from the wall, so if you have a large rainhead, consider a bracketed or support arm of some sort, the added support can come from the wall or from the ceiling. Something along the lines of this: For your hand shower, have a hose long enough so you can spray down the corners of your shower. Body sprays. The same. Good showrooms have spray displays where you can feel the spray of water. Once upon a time I was intrigued by body sprays, Then I tried them and thought them to be the silliest thing ever. Some folk put in two heads, stacked vertically, one one wall. It's a little more common to want four body heads. Usually on two opposing walls, stacked vertically. You don't want them spraying towards the door. Usually chest and waist height, so figure that out when plumbing. You will have to figure out flow and hot water supply issues, from your water heater to the shower drain. Shower supply valves allow a certain amount of "pass through". You need to make sure each valve can actually supply the water needed to feed the heads that you want it to supply, or you could end up with insufficient flow. With body sprays, I recommend a "loop" supply to feed them, so the last head has pretty much the same flow as the first head. For your shower drain, it needs to be sized to the number of heads you have in the shower. Doesn't matter if only a few of them can or will be on at one time. It's a simple counting of the shower heads. A 2" drain can accomodate a shower with up to three heads. With four or more heads, plan on two 2" drains or a single 3" drain. If your plumber says you don't need to upsize to a 3" drain with four or more heads, he's not complying with code. If you want a "car wash" shower with five or six heads going at once? Your half inch pipe may not be adequate. Sure, with adequate feed pressure behind it it might be able to feed all those heads. But high water velocities through the tubing can actually erode copper from the tubing, potentially resulting in leaks. It's not just a matter of the 1/2" tubing being able to supply the needed water volume. You can crank up the water pressure and get volume. But cranking up the pressure to get the volume increases the water's velocity through the tubing, and again, too high of a "feet per minute" flow through the tubing can actually erode the tubing away. So do be wary if your "contractor" tries to soft talk away all of your concerns. Half-inch supply tubing can work. But it should work because your shower was designed to work with 1/2" tubing, not because, as your contractor told you, "everybody else is doing it". You can help yourself by drawing out a diagram of your shower. Doesn't have to be fancy. Each body spray and each shower head will have a GPM rating. Same with each valve. Make sure the valves and/or diverters that feed those heads can pass through the needed volume of water. Very basic numbers here, but 1/2" can comfortably flow about 5gpm. For hot and cold, that's 10gpm combined. For a comfortable temp out of the shower valve, that gets derated to about 7.5gpm of shower-temperature water. If your body sprays are 1.8GPM, four sprays is 7.2gpm for the body spray set only. You can figure different GPM combinations. Then figure that GPM out of your water heater to see how long your heater can maintain shower temperature. Oh lord. I need coffee...good luck! Edit: I never proof read this after posting it. Egads.

If the walls are still open, then you can get a thermo control and two zone valves. The thermo control sets the temperature but the zone valves control each head. You could have a problem running both at the same time. 1. If you have a 40 gallon hot water tank, you could run out of hot water real fast 2. 1/2 plumbing supplies? Could choke it a bit. 3/4 supply line is best. 3. Drain: usually you go to a 2" drain over a 1 1/2. However,I would not be overly concerned with just the two heads (even at the same time) Its when you start adding body sprayers where you get these problems. Tell your plumber now! He will need to know how to plumb it.

Yay! I'm glad you decided to go with what your heart wanted...orb :) I have (what looks to be the same setup). Not sure that the difference is between yours and my Delta Linden In2ition. The two shower heads (one handheld) snap into each other. Both can be used together or independently. The handheld has multiple settings. The stationary shower-head as a couple of settings but I've not messed with that yet. One main reason I bought this one is that you can operate/adjust the water temp independently from the water on/off/pressure. If you know what temp you like your water, you can set it and forget it. If you could find a waterproof (maybe stick on) "hook" of some sort to hang the handheld on at a lower position for the kiddos, that would be great :) And don't worry about the finish. If something does go wonky with it, Delta has a lifetime warranty on the finish.

Currently my shower has a single shower head coming out of the wall. I am adding 2 10" chrome Kingston Brass rain heads to the ceiling, and I want to replace my current single shower head with a wall mounted hand-held shower head bar. What is the best solution for what I am looking for? I want to use the same location of the existing shower head as the water source for the hand-held and I don't want to spend a fortune.
