HydroRail-H Shower Column in Polished Chrome is rated 4.6 out of 5 by 8.
Rated 4 out of 5 by from Another great product from Kholer I am planning to remodel my shower and this HydroRail-H Shower Column will be a fantastic finish to the shower. The brushed nickel unit will match my Kohler Single handle faucet in my sink. The instructions could me a bit more explicit but if you read carefully, installation should not be a problem, even for the Do It Your Selfer. The quality of the unit is high end and the design is simple and attractive and will be easy to keep clean. I found one of the plastic molly bolt retainers to be broken at the nut, so this may pose a problem when installing. This had to happen in packing as all of the parts were well packed and protected when I opened the double box.

Rated 5 out of 5 by from Shower Column I am currently in the process of remodeling my bathroom and when completed the shower column will be installed. The quality is superb and the finish goes along with my towel holder and double toothbrush holder. It is definitely high quality and well worth the cost. I will enjoy having it installed upon the completion of the bathroom remodel and look forward to many years of use. I recommend this shower column.

Rated 5 out of 5 by from Amazing upgrade to a traditional shower I installed a Kohler slidebar in my master shower and absolutely love it. When I saw Kohler come out with HydroRail-H columns, I was eager to install it in the guest shower. Install is relatively easy if you're a regular DIYer. Directions are great --> read all directions first and follow them carefully. HydroRail is secured at the top and bottom by a bracket that requires three screws. Kohler designed the bracket with numerous, elongated screw positions that allow you to position the bracket over grout lines. For my install, 2 out of the 6 screw holes required drilling into tile and/or using toggle anchors. Kohler provides some of the best toggle anchors I've ever seen, which makes for a strong hold. I fitted the HydroRail with a Kohler shower head... now, our guest bath is used by more than just guest. The Hydrorail is expensive, but very bit worth it for a higher end shower and/or experience.

Rated 4 out of 5 by from DIFFICULT i thought this was going to be a nice addition to my shower. When I received it and read the directions I realized it was more than just an add-on to make my hand held shower easier to use, it was a whole new bit if plumbing that needed to be adjusted and installed. I don't want to hire a plumber and buy a brand new showerhead. I guess I'll hold on to it until I build a new shower.

Rated 5 out of 5 by from HydroRail-H Shower Column, Brushed Nickel When I first got this my wife was lets get it in, lets get it in. Superior product with great quality and a look that screams high end. Easy to install and the materials used are great quality. Loved the look once installed and it was a breeze to fasten in my shower area. You cannot go wrong with this addition to your bathroom with the look and workmanship that is in this product.

Rated 5 out of 5 by from Convert your shower to a spa! The Kohler Hydrorail H shower column is one of the newer features in shower hardware. It converts a regular showerhead to a handshower on a slide bar. Great for adjusting to the height of the person showering! Makes it much easier to wash my dog! It was pretty straight forward to install. It improves the look of my older shower stall. Makes it much more modern looking.

Rated 4 out of 5 by from Adds a luxurious look and spa-like feel to any shower. This shower column replaces your fixed shower head with a flexible hand shower, giving a spa-like look and feel to the shower. The column measures just over 19-1/2-inches in length, and is constructed of all metal with a brilliant chrome finish that resists fingerprints and waterspots. It can be installed in new construction or retrofitted for use in an existing shower. Before you install, to determine if the shower column is correct for your installation, you need to measure from the shower arm to the center of the mixing valve, and be very certain there are no obstructions in the wall. The included toggle anchors are innovative in their design and provide for a secure mounting of the lower portion of the shower column. A 45-degree offset allows for the hose to clear the mixing valve. Since mounting holes are required in the shower wall, installation of this shower column should be considered as permanent. The column doesn’t include the hand shower or hose, both of which are required before use. Aside from the obvious benefits associated with a hand shower that sits in a dock and can be used like a traditional fixed showerhead, this column features a one-handed height adjustment for hand shower. Lifetime Kohler warranty means no worries down the road. Installation and Care Guide is well-detailed with illustrations and written instructions. Adds a luxurious look and spa-like feel to any shower.

Rated 5 out of 5 by from great for new building Finish and style is great, is easier to put into a newly constructed space than in an existing bathroom. It is of great quality and extremely sturdy. I would highly recommend it if you are doing a bathroom make over and replacing the tile surround if you have one, if you happen to have extra tiles it will work fine on an existing tile wall. Overall, great for new construction, a bit more difficult on existing construction.
