This white Arvani measures 1200x600mm and mounts vertically, which makes it a straightforward fit for a larger family bathroom. At ΔT50 it puts out 2,487 BTU (729W); on a lower flow temperature expect less.
Connections are 1/2" BSP and it needs a pair of 15mm valves, sold separately.

Frequently asked questions
Will it fit a narrow wall?
Yes — 600mm is narrow enough for most awkward walls. The height is where it takes its space: 1200mm, so check you have headroom above the skirting and below any shelf or cabinet.
How does it compare with the other Arvani sizes?
This is the largest Arvani, at 1200x600mm and 2,487 BTU. The range starts at 650x450mm (1,060 BTU), so there are smaller options if the wall will not take this one.
What valves do I need?
Valves are separate. Angled where your pipes come out of the wall, straight where they come up from the floor. The connections are 1/2" BSP and take a standard pair of 15mm valves — in white if you want them to disappear against the rail.
Will the finish mark?
Powder coating is hard wearing and handles steam well. Clean the white finish with warm water and a soft cloth — no scouring pads, and nothing with bleach in it.

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.
