Whether you're updating your bathroom or replacing an old unit, this DIY guide from Tapron UK will walk you through the process of installing a towel radiator.

With a range of stylish and efficient towel radiators available at Tapron UK, you can find the perfect match for your bathroom's aesthetic and heating needs.

Preparation: Before diving into the installation process, ensure you have the following tools and materials on hand:

  • Adjustable wrenches
  • Drill and drill bits
  • Wall plugs and screws (usually provided with the radiator)
  • Spirit level
  • Pipe cutter
  • Radiator valves
  • PTFE tape
  • Safety goggles and gloves

Step 1: Choose the Right Location

Selecting the right spot for your towel radiator is crucial. It should be close to the plumbing connections and in a location where it can effectively dry towels and heat the room. Avoid external walls if possible, as they can reduce the efficiency of your radiator.

Step 2: Measure and Mark the Wall

Using the brackets provided with your towel radiator, measure and mark the wall for drilling. Ensure that the radiator will be level by using a spirit level. The height should be determined based on your personal preference and the radiator's design, but make sure it's at least 4 inches (10 cm) above the floor to allow for proper airflow.

Step 3: Drill Holes and Insert Wall Plugs

Drill holes at the marks you've made on the wall, ensuring they are the right size for the wall plugs. Insert the wall plugs, which will secure the screws and brackets in place.

Step 4: Attach the Brackets

Screw the brackets securely into the wall at the drilled and plugged points. Ensure they are tight and level, as they will support the weight of the radiator.

Step 5: Install the Radiator Valves

Before hanging the radiator, install the radiator valves on the supply and return pipes. Wrap the valve threads with PTFE tape to ensure a watertight seal. If you're replacing an old radiator, you may need to adjust the pipework to fit the new radiator's dimensions.

Step 6: Mount the Radiator

Carefully lift the radiator and hang it on the brackets attached to the wall. Make sure it's secure and level. Connect the radiator to the valves, tightening the connections with an adjustable wrench. Be careful not to overtighten, as this could damage the valves or radiator.

Step 7: Fill and Bleed the Radiator

Once the radiator is connected, slowly refill the system, checking for leaks as you go. Use a radiator key to bleed the radiator, releasing any trapped air until water begins to flow out of the bleed valve. This ensures that your radiator heats up efficiently.

Step 8: Test the Radiator

Turn on your heating system and check that the radiator heats up evenly. It may take a few minutes for the radiator to reach its full temperature. Inspect all connections for leaks and tighten if necessary.


Installing a towel radiator is a manageable DIY project that can add value and comfort to your bathroom. By following these step-by-step instructions, you can ensure a successful installation. Remember, if you're not confident in your DIY skills or encounter complex plumbing issues, it's best to consult with a professional plumber. Explore the wide range of high-quality towel radiators available at Tapron UK to find the perfect model for your bathroom renovation project.
