Question: Are the components all bronze or copper or are some plastic or other materials?
Document: Item was very nice. The only issue is the color. It is actually a copper color not bronze. We have not installed it yet as our contractors were hired for the end of February.
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.
We renovated our master bathroom and this oil rubbed bronze shower head added class in our shower room. I love it.
Delivery as advertised. No problems there. Install was easy. Color is off a little for some of the parts (hose) but worked for me since everything i installed was oil rubbed bronze.
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.
These showerheads are fantastic! We have three if them. Not only are they a great match for all of our other oil-rubbed bronze bathroom hardware, but they work great. The three settings on each head are quite sufficient, and the water saver option allows for independent or simultaneous operation of either head. When our contractor first installed them, we had a hard time getting the handheld heads to rest securely in their cradles.
We love our new Mariner shower head system! It's is very well made and has a beautiful bronze finish. It is not as dark as our other bronze fixtures but it looks great with our tan/brown glass tiles in the shower. The flow of water is strong enough that we didn't have to remove the water restrictor as we have with past shower heads. The hose is long enough that I can wash my very short dog with no problem.
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.
Answer: yes
