How To Fit A Heated Towel Rail

A heated towel rail helps get your towel warm while you’re in the showers or tub. With this shockingly affordable setup, you can say bye-bye to shivering after cold baths.

The love for warm towels has made some people make use of a dryer. This method is, however, costly and inconvenient. Heated towel rails also keep your towels dry when not in use.

Types Of Heated Hanging Towel Rails

  1. Electric Towel Rail – This rail plugs into the outlet on your wall.
  2. Fixed-in Electric Towel Rail – This version is wired into the electric system of your home and mounted on the wall.
  3. Hydronic Towel Rail – This version is powered by the hot water system in the house. The radiator is connected to the radiator lines inside the walls or floors.

There is a specific installation process for this system, and a few tools and materials will be required.

Supplies Needed

First off, you’ll need the essential installation tools, such as tape measure, pencil, Allen key, drill, screwdriver, and a hammer.

Then you’re going to need an adjustable spanner, masonry bit, screws, rule plugs, spirit level, and a PCFE tape. Depending on your pipework, you should either get a straight-through valve or an angled grab.

Now that you have all that you need, we can begin the process.

Setting Up The Towel Rail

1. Plug-In Electric Heated Towel Rail

  • Find The Studs – To avoid the item getting ripped off the wall, drill only on the house’s studs. You can use a stud-finder to locate where your item can be firmly fitted. Decide on a location that is in close proximity to an electrical outlet, so that the cord won’t overstretch and can be plugged in. You should assess the cord’s length before moving further.

If the studs are in an unsuitable place for fitting an electric towel rail in the bathroom, try using toggle bolts that have wings and can pop open inside the wall to prevent what you’re hanging from getting loose on the wall.

  • Set Your Markings – Make use of a pencil to mark out the spot on the wall where you intend to hang your support anchors. The typical towel rails have 4 support anchors, with two on each side. In some cases, the support anchors have separate pieces to attach to the wall. The towel rail is then mounted during the last step of installation.

To understand how to properly install your heated towel rail, endeavor to read the instructions that come along.

After you’ve made the markings, use a tape measure to confirm that the anchors are at equal length from the ground up. If the lengths are different, your rails will end up unbalanced.

  • Drill The Hole Then Hang The Rail – In the middle of the markings, carefully use your drills to make holes in them.  If you had to make use of toggle bolts, you could wiggle the drill up and down to make the hole a little bigger.
  • Hook The Rail Onto The Support Anchors – This is the final step. Check and follow the instructions that came with the rail kit, and ensure you hang it on properly.

2. Hydronic Towel Rail

The optimum method of installing a hydronic towel rail is by replacing the old radiator with the heated towel rail.

  • Find the Pipes and Take Your Measurements – The initial step is locating the supply and return lines for the radiator. Once you’ve removed the previous radiator, you should see copper pipes sticking out of the wall and floor. These pipes will be linked to your new heated towel rail.

Next off, measure the horizontal and vertical distance between the present pipes and the towel rail’s supply and return lines. You can use this number to determine if the extra length of the copper pipe is needed.

  • Install The Towel Rack – Next, adhere to the above instructions on how to measure and install the towel rack on the wall.
  • Connect To The Pipes – After you’ve firmly mounted your towel rack to the wall, you’re to connect the copper pipe in your home to the rail’s supply and return lines.

Use an appropriate length of copper pipe to connect both sections of pipes. If you have to solder them together, get something to cover your bathroom walls and floor.

That’s it! And now that you know how to fit a heated towel rail to your bathroom by replacing a water radiator, you are prepared for those cold days.

3. Fixed-in Electric Heated Towel Rail

It is installed by hard wiring the rail into the bathroom’s electricity supply. This method doesn’t require plugins to hide the loose cords effectively. It’s also a great method if there’s no radiator in the bathroom.

It should be noted that this method can prove dangerous and should only be carried out by professional, licensed electricians.
