Thanks for the feedback. I really don't know why I am having so many issues/problems making decisions for this bathroom. Perhaps because we started serious DIY renovations on this 70's house 6 years ago, were going to add an addition for this BR and had hired and started to pay a design/builder who we basically fired after receiving an estimate of $70K to frame a 210sq ft addition! I think I went through a grieving process at losing my dream bathroom (life intervened, and we ended up helping our son buy his first home), and it took me over a year to actually get this project moving. So, good news, I just handed over my Visa, and I'm getting the Riobel system in brushed nickel with thermostatic valve and volume control! Emco also carry the Moen Iso line, so I'm getting all my BR accessories in brushed nickel too at less than the HD price in chrome, so I'm one happy camper. I went to a plumbing supply store, and asked them to give me a quote to compare apples to apples...so she knew without my saying so, that I had gone to another showroom. When I rec'd the quote this morning, it was lower for all items except the main valve, which was higher by $22. I told her it was good, except for the one valve, and she met that price. I wasn't pushy or demanding, just honest. I hope to be able to share that the Riobel system works great! Supposed to be very good, and I like the idea that it is a Canadian company, made in Canada, and I don't have to worry about shipping, duty and having to deal with a foreign company if problems occured... Glad I didn't have to give up volume control, my Brushed Nickel finish (which in some lines was going to be exorbitant), or my thermostatic valve! On to the next..gotta pick between two colours of my limestone lookalike porcelain tile...

Here's what we got: Rough valve; thermobalance III - 06628 Valve Trim (the part you see with lever) - 06067 Showerhead - 06126 Small showerarm - 27411 Handshower - 06127 Wallbar - 06890 Metal showerhose - 28116 Wall outlet for handshower - 27454 We bought Polished Nickel; the color code is added to the above part number. You buy the valve and trim, depending on how many functions you want (just shower; shower/tub/ etc.) Also, I think for a tub/shower, I would do a wallbar with handheld and tubspout. I sort of wish we had done that with our tub/shower that we just finished; we just did a standard showerhead. We're using the Hansgrohe pieces I listed here for a master shower. Good luck! It is very confusing. I was really happy to discover the local dealer knew what we needed.

We used the hansgrohe thermobalance III. Excellent control. you can leave the temperature setting in a desired position.

I'm sure that you can find a suitable Kohler product, as they're one of the biggest companies. I have the Sustainable Solutions International F2040 which looks great and works amazing for me. I got it because it reduces water consumption. Most of their products work fine with only one valve but I'm afraid that my technical knowledge should be taken with a grain of salt as I don't use a handheld. Depending on how much you're willing to spend, Graff also makes some really sexy luxury fixtures that would definitely up the "wow" factor of your bathroom. Hope this helps at least a little! Hopefully someone else can better answer your technical questions..
