Rufinorox, It looks like below pic except with a slide bar instead of the little fixed holder. I usually find and order things on the internet, but for this ended up at a Ferguson showroom. I would have been clueless about all the parts and pieces needed to put this together without their help. AND, I got to see it in person!! I never thought I'd go to a plumbing /fixture showroom but in this case it was well worth paying a bit more than the online price.

I am a homeowner/DIY'er who recently purchased a Moen Eva polished chrome shower faucet trim kit at a greatly discounted price from eFaucet.com along with a CC shower valve and received a pro-grade product un-available to me locally except at a more expensive plumbing supply house that would of charged me a lot closer to list price. Moen sells shower/bath valves with either IPS-Iron Pipe Size, CC-Copper Connection and CC with stops which have built in water shut-off valves that allow servicing of the mixing valve with out shutting off the water throughout the whole house. When shopping at any of the big box stores you will most likely only find shower and bath faucets that are all IPS connections. IPS connections are threaded pipe where as the CC connection valves are soldered copper. In my experience threaded IPS connections are prone to leakage over time and are inferior to soldered copper. Other than the valve connection method the products are identical. The big box stores sell these threaded connection products to their customers primarily because they require little skill to install and that is their market base. Although I could of certainly paid more for a faucet than what I did, I believe there is a diminishing return on investment. Furthermore, if I ever required a part to repair my new faucet in the future, Moen has the parts available to me with lifetime warranty replacement by mail or for more immediate need at the local big box or hardware stores. That option is often limited, unavailable or even unknown regarding many expensive import faucets.

I'm going to answer this but there are others more qualified and should be last word. Here are my thoughts, hand helds and shower heads are just a matter of attaching to the end of 3/4" or 1/2" pipe so no trouble with that. As for the valves in the shower I would think it would depend on how far along the construction is. Not so much for the pipe size cause if your plumed for 1/2" and you valve is 3/4 you can reduce but I would think placement forwards and backwards is the issue.

You are right, that is the best solution-if you are going to mostly store the shower curtain inside the tub. I'm only going to be using this for an occasional shower at, if at all so the shower curtain will usually be hanging on the outside of the tub. Even I even keep it hanging; I may just have the contractor install the rod and skip the curtain for now. Can anyone who showers with a rain shower help me??? Does the water splash less towards the back wall???
