Question: Is this compatible with my existing Moen valve?
Document: Would have been a five star if the valve to switch heads could be reached on the upper shower head by my wife who is 5.1 -
Excellent quality, fast shipping,The diverter valve only allows spray from one head at a time. This is not made clear in the description. They do sell a diverter that allows for both to be used, but it is another $35.
Set the water temp, leave the main valve open and turn on/off water flow as needed and maintain a constant temperature. I rate this product an A+ and well worth the money.
The bronze finish matched our existing bronze hardware, and we haven't had any problems with scratching, corrosion or wear. We have fairly hard water in our house, but when we get build-up on the flexible hose it comes right off with a little bit of CLR. This is an easy way to turn your shower into a dual-head setup without calling a plumber.
We bought this system to replace the shower head on our Danze Bannockburn oil rubbed bronze shower head. Boy are we happy with the purchase!First of all the finish is pretty much and exact match. Whew! !Secondly, we were really impressed with the quality of the whole system. The shower heads, the control valve, the hose, the grab bar, and the height adjuster are all high quality pieces.
I ordered this shower head combination because 99% of the others I had looked at were just ugly;...we just remodeled our main bathroom and we wanted something nice--this functions very well and is also an elegant piece of hardware. Each shower head turns on separately, so if you prefer them both on at once you'll have to use a different diverting valve. We love it as is--the bronze color closely matches our other fixtures, but is a bit more reddish in tone.
I was somewhat skeptical when I ordered this unit because the price was so much more reasonable than those at the big box stores. It, however, has exceeded my expectations - my wife and I love the dual shower heads. The diverter valve, along with the individual adjustments available on each shower head, allows several combinations of water flow. I would highly recommend the Mariner 2 Combination Shower Head System.
The diverter itself operates so easy and smoothly that I was pleasantly surprised since my previous push pull diverter worked so hard my wife couldn't operate it. This one turns like a valve with a lever handle, very easy.edit: I was wrong about the hose. The one that came with this shower is the good one. Very flexible yet hangs straight.I would 100% recommend this shower set up to anyone. High quality, beautiful looking and very functional. It's the best deal for the money I've seen.
We were really impressed to find so many pieces that were machined out of metal and NOT cast out of plastic. Every piece fit perfectly. Every hole and every thread was perfectly manufactured. Installation was a breeze.The spray provided by the shower heads is far superior to the Danze heads that we had been using.Adjusting the grab bar spayer height is easy, simple and it holds its adjustment.
We were bathing our two and a half year old daughter in a small plastic tub in our shower/bathtub. Went on a vacation overseas and couldn't really take along her little tub, but where we stayed had a shower with a second shower wand and she loved it. Home from vacation started looking around the stores here for a shower set up that would match our fixtures. Couldn't find any so looked on the web. Saw some rather expensive ones, then found this on Amazon.
