Narrowboat Towel Radiators

Towel Radiators Built for Narrowboat Living

Narrowboat bathrooms are small, and the heating system is rarely a standard domestic gas boiler — so choosing the right towel radiator matters. This collection brings together the compact, efficient models that work best on narrowboats and canal boats: slim widths from 200mm, low BTU outputs matched to tiny spaces, and three fuel-type options to suit however your boat is set up.

Which Fuel Type Suits Your Boat?

Central Heating (CH) models are the most popular choice if your narrowboat has a wet central heating system fed by a diesel boiler or solid fuel range. These connect directly into your existing pipework using standard compression valves — the same 15mm fittings used in domestic properties. Water temperature from a diesel boiler is typically 60–80°C, which is well within the operating range of all CH towel rails.

Dual Fuel models are ideal if you want year-round flexibility. Run off the boat's wet system when cruising or moored off-grid, then switch to the electric element when you're on a marina shore power hookup and don't want to fire up the boiler just to dry a towel. One valve is simply closed to isolate the CH flow when running on electric — no extra plumbing needed.

Electric-only models suit boats that are permanently moored at a marina with a 240V shore power connection. They're also a clean solution for a forward cabin or utility area that isn't plumbed into the boat's heating loop. Note: all our electric elements run on 240V AC — they are not compatible with 12V DC leisure battery systems.

Getting the Size Right

Most narrowboat shower rooms are under 1.2m wide, which means compact towel rails in the 200–400mm width range fit without dominating the space. Heights up to 1,000mm give a good number of drying bars without encroaching on low ceilings. For BTU output, a narrowboat shower room or toilet compartment typically needs no more than 800–1,200 BTU — so even our smaller models heat the space effectively.

Pipe centres on a narrowboat are usually set at the same distances as domestic bathrooms (the distance between flow and return pipes is the rail width minus 50mm), so standard off-the-shelf valves and pipework fittings apply.

Which Finish Lasts Longest Afloat?

Chrome and brushed stainless steel handle the damp, steam-heavy atmosphere of a narrowboat bathroom particularly well and are our most popular finish in this collection. Matt black and white powder-coated finishes are equally durable in normal use — all our towel rails carry a 5-year manufacturer's guarantee regardless of finish.
