Update: Everything is quite well after about a year and a half of use with the shower panel and it still looks brand new! I did replace the mixer valve only because I wanted a true thermostatic mixer valve. I used the Rozin Solid Brass 1/2" Thermostatic Mixer Valve for Shower System Water Temperature Control Chrome Finish, from amazon.com. It matches the other valves, was an easy replacement, and is a definite improvement.

I installed this in my motorhome right after it was delivered, this is one box that wasn't going to gather any dust..
Installation:
- I removed my old RV fixtures and used EternaBond RSW-4-50 RoofSeal Sealant Tape to seal the screws and large holes for plumbing access.
- I held the fixture up to see where to mount it, unfortunately the existing plumbing access holes determine where this has to go so it is a little off center and that will have to be fixed at a later date. I think getting an appropriately cut piece of polished aluminum or preferably stainless steel to cover the area will allow me to move the shower fixture into a better location. Another expected problem was the height of the fixture, to resolve this I cut the frame around my skylight that is over the shower to allow the new fixture to go up another 1 1/2 inches; and wallah another problem resolved. Again I used the sealant tape to close up the cuts I made.
- I marked the locations to install the top mount and then measured down 37 3/8" and installed the lower mount.
- I changed the batteries to a quality AA battery and put the battery pack in the pocket that seemed to be an obvious place for it to go.
- I installed the handheld shower flow through holder with another screenless washer and my favorite handheld shower unit because the one that comes with the unit looks like a cheap piece of plastic junk.
- Time to do some plumbing, fortunately the RV uses standard 1/2 inch FIP faucet connectors so it made the installation very easy.
-- I installed two new screenless washers in the RV side and then tightened on the two 1/2" x 1/2" elbows that were included in the installation kit. I used screenless washers because I have filtered water and I also have an on-demand water heater that requires full water flow to work properly.
-- I then put two more screenless washers in the fixture hoses and tighten them down to the elbows.
-- Make sure you don't kink the hoses in the fixture or you will have problems, by the way they are very easy to kink.
- Now I simply hung the unit up and admired it for a minute.
Time to get naked and get in the shower (sorry for that mental picture, LOL). I got in got the temp adjusted right and tried the various features and they all worked very nicely. The only thing I didn't really care for were the two large round fixtures that really weren't very powerful. Everything else was great. The LED lights weren't working, oops remember that switch on the battery pack! I reached around and pulled the battery pack out and turned it on and presto I had LED lights which were kind of kool.

As a side note, set your temp where you like it and leave it alone, use the feature valves to turn the water off and on and you will always have the perfectly adjusted shower, at least until your significant other changes it.

I did get the shower panel at a much reduced price because I bought a slightly damaged unit, but it doesn't affect anything and I readily took care of the minor damage.

I cannot say enough about how great this shower panel is both in appearance and functionality, not to mention how easy it was to install. It was really very convenient that everything was included in the installation kit for a standard install. The only features that could use improvement is the handheld shower and those big rings, but then maybe somebody else likes them. I'm going to buy another one for my parent's home.

The shower is amazing it works great and looks gorgeous.

I had to increase my supply lines from 1/2 to 3/4 for water pressure. I'm not sure if that is normal but I'm on a well and our pressure is pretty bad. That being said once I got that done I installed the new shower pretty quickly and it's been great! Love being able to turn on and off without adjusting temperature so it's already set perfectly every time I step in the shower!

Impressed with the exterior design and look. The plastic wand and tub spout look good but would be nice to have had those in metal. Installation was pretty straightforward however I would not recommend installing this if you are an average DIYer. Internal components seem to be attached and connections do not leak however the connectors and plumbing used may end up failing overtime, especially with the pressure at my house. I have 80 lbs of pressure (which is rather high) which leads to great pressure with this unit even with multiple options turned on, but the fittings may not hold up with that overtime. Only reason for 4 stars is because of the fittings and plastic parts, but that is expected with a unit of this price. The light feature I thought was overkill until I installed it and checked it out. Will make for a nice relaxing shower first thing in the morning! The battery packs are somewhat easy to get to, I made sure I could access them when I mounted the unit so I don't have to take the whole thing down to replace the batteries. Overall a good purchase in my opinion. Will update if there are any issues that arise.

Great product with excellent design
