Pilastra takes the look of a column radiator into the bathroom, with dual columns you can hang towels over. Clean white blends into light walls so the radiator does its job without dominating the room.
2 sizes are available, with heat outputs from 2,818 to 4,268 BTU/hr at ΔT60. It is supplied with everything needed to fix it to the wall. It runs on your central heating; valves are sold separately.

Help choosing
A towel rail should keep the bathroom warm, not just dry towels. Check it's powerful enough for the room.
Enter your room size to see the heat output you need.
- Match the output to the room. Use the BTU figure from the calculator. In a bathroom, a towel rail alone often heats a small room; bigger rooms may need a radiator too.
- Check your connections. Measure the gap between your pipes and choose valves to suit: angled, straight or corner (see the valve helper on our valve pages).
- Heat pump? At the lower water temperatures heat pumps run at, expect roughly half the listed output.
- Summer use. Central heating rails only warm up when the heating is on. A dual fuel kit adds an electric element where the rail supports it.
