Question: can you change the shower head for the stationary unit?
Document: 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.
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 -
We renovated our master bathroom and this oil rubbed bronze shower head added class in our shower room. I love it.
This shower head is absolutely beautiful. It is rich and elegant, Glad I made this choice.Don't hesitate, buy before it goes away.ladyjatl
It turns out there is some gizmo internally that is required to install this and I ended up having to buy another (the cheapest I could find) shower head to get that gizmo so I spent an extra $25 at the store and had to delay installation
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.
1/4&#34; glass and tile bit is what you'll need.The shower set looks great (except for those scratches) and the family loves how it functions. It is still new but has a heavy quality feel about it and I think it will last a while. The great advantage for a family is you can put one head down low for the kids and one up high for the adults.
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.
