A heated towel rail does two jobs: it warms and dries towels, and it adds heat to the bathroom. Choosing well means looking at both. This guide covers the types of towel rail, how to think about size and heat output, which materials to consider, and what to check before you order.
Central heating, electric or dual fuel?
The first decision is how the towel rail will be heated.
- Central heating: connects to your heating system and uses hot water from your boiler or heat pump. It only works when the system is on.
- Electric: has a built-in element and plugs into the electrical supply (wired in by a qualified electrician). It works independently of the central heating. See electric towel rails.
- Dual fuel: connects to the heating system and also has an electric element, so you can warm it when the central heating is off. Check the product specification for how the element is supplied.
The full range is available as heated towel rails. For a comparison of electric and central heating, see our electric heating guide.
Size the rail for the bathroom, not only for towels
Bathrooms are often small and lose heat quickly through tiles, windows and extractor fans. A towel rail that is too small may dry towels but leave the room cool. A rail that is too big wastes space and costs more to run.
- Work out the heat the bathroom needs, in watts or BTU/h. Our radiator size guide explains how.
- Compare it with the output published for the towel rail you like. Remember that outputs are normally quoted at a standard test condition, and a system running at lower temperatures will give less.
- If the towel rail does not meet the whole requirement, you can combine it with another heat source, such as underfloor heating.
Covering a towel rail with towels reduces the heat reaching the room. This is normal, and worth allowing for if the rail needs to do most of the work.
Choose a shape and style
- Ladder rails have horizontal bars, which suit towels and give plenty of hanging space.
- Flat panel or vertical styles have a smooth look that works in modern bathrooms.
- Different bar spacing affects how many towels you can hang and how easily air circulates.
Measure the wall, and check the clearance for doors, shower screens and a bath or basin nearby.
Materials and finishes
Most towel rails are made from stainless steel, aluminium or steel, often with a finish such as white, black, anthracite or chrome. Each has its own character:
- Stainless steel towel rails are resilient and well suited to humid rooms.
- Aluminium towel rails are light and respond quickly when the heat is turned on.
- White, black, anthracite and chrome finishes can be matched to taps and other bathroom fittings.

Connections, valves and fixings
- Pipe centres and position: if you are replacing a towel rail, measure the existing connections from centre to centre.
- Valves: check whether valves are included with the model, since this varies. See radiator valves and towel rail accessories.
- Wall fixings: a filled towel rail is heavy. Check the wall is suitable and use fixings recommended for the wall type.
Bathroom safety
Water and electricity need care. If you choose an electric or dual fuel towel rail, have it fitted by a qualified electrician and check the IP rating suits the zone where it will be installed. Plumbing work on a central heating towel rail should be done by a competent installer.
Quick checklist
- Decide: central heating, electric or dual fuel.
- Check the output against the heat the bathroom needs.
- Choose a shape and size that fits the wall.
- Pick a material and finish that suit the room.
- Match pipe centres and valves, or plan the pipework change.
- Confirm the wall and the electrical supply (if relevant).
