How to Install a Heated Towel Rail

Please note: Our ‘How-To’ manuals are intended only as a guide to assist you with common home heating tasks. Please do not attempt to undertake this task if any of the instructions are unclear, or if you are in any doubt about what to do. Instead, seek advice from a professional.

What You Will Need:

  • Hammer        
  • Tape measure  
  • Screws
  • Grips               
  • Wall plugs
  • Pencil
  • Spirit level     
  • PTFE tape                  
  • Towel rail
  • Cloth        
  • Masonry bit              
  • Adjustable spanner
  • Phillips screwdriver
  • Drill driver (with hammer action, needed to go into solid surfaces like brickwork and tiles)
  • Allen key (specialist version, needed to make the connection from radiator valve to the radiator)             
  • Rad valve (angled and straight)


Step 1

Install the nuts into the top of the towel rail.

Step 2

Turn radiator over. The radiator tails go in this end. A radiator key, large Allen key or spanner will insert them. If there is no sealing ring around the tails, seal it using PTFE tape, wrapping 10-15 times.

Step 3

Screw the tail directly into the radiator. Tighten using a spanner. Repeat with the other tail.

Step 4

Measure the width of the rail, and mark the centre point of the pipes.

Before you begin drilling, take a hammer and nail, and hammer a small dent into the wall at the drill-hole points. This will stop the drill from sliding on the tiles.

Step 5

Drill into the tiles. Once the drill has gone through the tile, change the drill setting to hammer action. Do not begin drilling with the hammer action, as this will shatter the tile.

Take wall plugs. Hammer wall plugs in. The wall plugs must be hammered beyond the tile, into the brick surface, to avoid splitting the tie. Get a screw and hammer it through until the plug hits the brick work and is no longer in the tile.

Step 6

Fit the brackets. Remove centre screw. Get fixing screw and place through the hole in the bracket. Take the Phillips screwdriver. Place into hole. Do up. Repeat on the other side.

Step 7

Take a spirit level and check they are level. The brackets are now fixed.

Step 8

Take the retaining bracket and part it. The rail will sit within this groove.

Step 9

Place bracket inside. Get the lock in screw and replace back in to the hole it came out from. Do up tightly and push bracket back. Repeat on other side

Brackets are fitted. Now it’s time to fit the towel warmer.

Step 10

Turn the towel warmer upside down. Take locking nuts off at both sides and place these onto the pipework that is coming out of the wall.

Step 11

Place the towel rail on the brackets.

Step 12

Take bracket. Place in the screw fixing and do up loosely with a screwdriver.

Step 13

Make the connection to the radiator. Pull pipe through and leave in position, ready to fit the bottom brackets.

Step 14

Fit bottom brackets.

Step 15

Attach the towel warmer.

Step 16

Wrap PTFE tape around the threads of the brackets. Tighten up the connections using a spanner and a cloth to prevent scratches.

Step 17

Check fittings are all tight.

Fill radiator up. Open the valves. The water will start to rush through.
