Customer Reviews

HydroRail Bath/Shower Column in Brushed Nickel is rated 4.7 out of 5 by 10.
Rated 5 out of 5 by from Whole new shower experance Wasn't too sure if i was going to like this style of shower but once you try it your hooked. Nice looking design very functional and very easy to install. This is a bit pricy by the time you add in the hand shower and the large rain head but vs. the cost of tearing out the wall and replumb for this style of shower it’s much less evasive. You can do this with a little time, few tools, minimal effort and you have just updated your shower to the next level. Please note in my video I did not use the provided mounting hardware, I’m in the process of renovating a few rooms and I didn't want to mount this in tile until I tried it first. Last thing I want was to drill into my new tile if I didn't like this and have to patch new tile.

Rated 5 out of 5 by from It is almost too nice for our bathroom Wow is this shower rail nice. It works really really good. It looks so nice and shiny. This is just the trick to get that personalized message from your hand held shower head. I did run into an issue with mounting this shower rail. I tried to install it and it stuck out an inch and a half from the shower surround so I had to go back and move in its mounting point. Otherwise I love it.

Rated 5 out of 5 by from Very Cool and Beautiful This is such a beautiful product I can't recommend it highly enough. It's very solid and nicely finished and it is just the right height for my wife and I (I'm 6'2" and my wife is 5'6"). I hate having to bend over when shower heads aren't tall enough, but my wife likes to be able to adjust and change the shower head direction so it can't be too high. It's easy to install, only needs a few screws drilled with a masonry bit into tile or stone. I had it up in less than 20 minutes. We bought a big square shower head with the same finish and they look great.

Rated 4 out of 5 by from Nice Looking addition to the shower area......BUT EXPENSIVE The HydroRail does two things quite well. First ... it adds a tremendous amount of versatility with the availability of a large rain head shower and the handheld shower wand. Second, this rail is extremely nice looking. All of this can be done in about an hour without needing to tamper with the plumbing inside the wall. However, I think the HUGE downside to this is the cost. For $450, I think a shower head and wand should be included. I think it overprice.

Rated 4 out of 5 by from Bath/Shower Column The HydroRail Bath/Shower Column in Oil Rubbed Bronze has a very nice finish that will last along time if it is cleaned regularly. The installation instructions should be rewritten because it does not explain the correct way to install it, this is not something that the normal homeowner should try to tackle unless they have the skills. The HydroRail is wonderful when it is finished, works great, and looks beautiful on top of it.

Rated 5 out of 5 by from nice design The installation of this wasn't as bad as I thought it would be. I would recommend watching the Home Depot install video first just to get a good feel on install. It has a very nice finish, didn't see any runs or weak spots in the finish. My favorite part is all important install pieces are metal and not plastic. If mounted to studs it also works as a slip handle.

Rated 5 out of 5 by from Install appeal The shower column is supplied as just the column. You will need to add (or reuse) your existing shower head and shower wand. Installation was fairly straightforward, with the exception of the mount that goes where your existing shower pipe exits the wall. The plate is fairly small, so the pipe needs to be almost fully enclosed to enable you to mount the bracket to it. The manufacturer provides plastic toggle bolts. It took about 30 minutes to install. I like the fact that the rail brings the shower head out and away from the wall, and the wand is out of the way. The wand holder is fully adjustable and can be slid up and down the rail and locked in to position wherever you prefer. The bathroom we installed this in was already very nice, but now it has a spa like feel. It makes a statement. Look at the pictures and video for more information.

Rated 5 out of 5 by from Gorgeous Spa Extravaganza Positively G.O.R.G.E.O.U.S. Kohler Hydrorail transformed my ordinary, plan bath/shower combo into the spa excursion I'd always wished for. The column replaces the fixed shower head with an adjustable height rail which allows you to experience an overhead rain shower. The old fixed showerhead sat too low on the wall and could never be adjusted for a rain shower. A person over 5'6" would have to bend over underneath the showerhead to wash their hair. The Hydrorail adjusts to the height you choose for the perfect spa delight. Most showerheads will fit the Hydrorail, because it is a universal size. The bigger the better to feel like you are inside a waterfall. The Hydrorail offers a hookup for a handshower, too. It is literally the best of both worlds. My Hydrorail column is a beautiful vibrant polished nickel that coordinates very well with other bathroom accessories that were already in place.
