This shower rail is beautiful. I bought for my home installing it 10 years ago; and for 10 years, it's given me excellent results. The quality is second to none. I have not come across any shower faucet I would want to replace it with.

Fortunately, Kohler has a limited lifetime warranty on this device. Last week, after 10 years of excellent work the inner workings of the handle wore out. The diverter no longer stops water. Both heads flow water all the time now. Time to get a replacement part for it.

The Best of the Best of the Best

Great product.  Easy to install.  Good remodeling option.

Didn’t have to rip out the shower wall. Such a great solution. Extraordinary sales folks made the buying easy.

Easy to install and pleasant to use

If you have one valve and you want to have two options - a rainhead as well as a handheld - this is a wonderful option.  I am very happy with it!

Excellent option!

In 2019, we did a major remodel of our master bathroom that afforded us a very large two person shower with dual rain showers.  The contractor opted for the Kohler Hydro Rail shower column.  About two months ago the valve that directs water to the rain shower or to the hand wand began to fail, meaning water started coming from both.  A local plumber said the design prevented access/replacement of this valve and we would have to order an entirely new one.  Took a bit to find it but we did and wow, it was expensive.  I should have replaced both with something else that was just as good but cheaper and allowed for this valve to be serviced.  Terrible design/engineering.

Expensive but designed for failure

We purchased this system 9 years ago when we built our custom home.  It worked fine until this year at which time the upper connection of the HydroRail began to leak behind our wall.  The culprit was failure of the two o-rings that are on the nipple that comes out of the wall and connects to the HydroRail (see photo).  There is no way to know how long the leak had been occurring, but by the time we discovered it we had a steady stream of water coming out of the fitting behind the shower wall.  We are now into an extensive restoration project as a result.  As I understand it, all HydroRail systems from Kohler use this o-ring setup.  So, unless you want to disassemble your shower fixture periodically to check and/or replace your o-ring, you might want to go a different route.

Beware of the O-Rings
