What Size Towel Radiator Do You Need?
Choosing the correct size towel radiator is essential for heating performance.
You should consider:
- Bathroom size
- Wall space
- Number of towels
- Heat output (BTU)
Small Bathrooms
Compact vertical towel rails work best for ensuites and cloakrooms.
Medium Bathrooms
A mid-sized ladder towel radiator usually provides enough heating and towel space.
Large Bathrooms
Consider large designer towel radiators with high BTU output.
Understanding BTU Output
BTU (British Thermal Unit) measures how much heat a radiator produces.
The larger your bathroom, the higher BTU output you’ll need.
General UK BTU Guide
| Bathroom Size | Recommended BTU |
|---|---|
| Small Cloakroom | 1000–2000 BTU |
| Medium Bathroom | 2000–4000 BTU |
| Large Bathroom | 4000+ BTU |
If your towel radiator won’t fully heat the room, you may need an additional bathroom radiator.
