300mm Wide White Towel Rails
The 300mm wide white towel rail is the compact ensuite specialist — narrow enough to tuck into the gap between a toilet cistern and a door frame, yet tall enough to make a statement at 1800mm. Uniquely within our white range, the 300mm width is available at 400mm height, making it the only option for a dedicated hand towel rail in a cloakroom that needs a discrete warming point rather than a full-height unit. From 337 BTU at 400mm height to 1,494 BTU at 1800mm, the same 250mm pipe centre covers the full spectrum from supplementary warmer to primary heat source for ensuites up to 10m².
Pipe Centre Note: When installing a 300mm wide white towel rail on central heating, your pipework should be set at 250mm centre-to-centre for straight floor-entry valves. For wall-emerging pipework, factor in angled or corner valve offsets.

Why Choose a 300mm Width Towel Rail?
The 300mm width covers two distinct use cases cleanly: the 400mm height variant is a low-profile hand towel rail — discrete, neat, and capable of warming a hand towel in a cloakroom where a taller unit would dominate. Scale up to 1800mm and the same 250mm pipe centre gives you a full-height primary heat source for a compact ensuite.
- Ideal Room Suitability: Compact ensuites (3–7m²), cloakrooms needing a dedicated hand towel point, narrow wall sections between a vanity unit and shower enclosure, and alcoves where 350mm would protrude too far into the room.
- Towel Drying Capacity & Ergonomics: A standard hand towel (50cm wide) hangs flat with 25mm of rung showing each side. A bath towel (70cm wide) folds once to 35cm — fitting across the 300mm rungs with 35mm spare each side. The 400mm-high model holds one hand towel; the 800mm and above accommodates multiple towels across its bar groupings.
- Installation & Wall Space Considerations: Allow 370mm of clear wall space minimum — the 300mm body plus approximately 35mm either side for valve connection points. The 250mm pipe centre is compatible with many existing installations where a 300mm-wide panel radiator was previously fitted.

Key Installation & Accessory Compatibility
- Pipe Centre Alignment: Fixed at 250mm across all heights in this width range.
- Required Valve Hardware: Pair your rail with our Chrome Radiator Valves — select straight valves for floor pipework or angled/corner valves for wall pipework.
- Dual Fuel Conversion: To operate your towel rail in summer when central heating is off, install a Dual Fuel Kit and electric Heating Element.
Delta T (ΔT) Thermal Output Calculations
- ΔT50°C Standard (Boilers): UK baseline (BS EN 442) — 75°C flow, 65°C return, 20°C ambient.
- ΔT30°C Low-Temperature (Heat Pumps): Multiply ΔT50 by 0.515 for systems operating around 45°C–50°C.
- ΔT60°C High-Temperature (Legacy Systems): Multiply ΔT50 by 1.268 for older systems at ~80°C flow.

Frequently Asked Questions
Q: What is the pipe centre measurement for a 300mm white towel rail?
A: The standard pipe centre for a 300mm wide white towel rail is 250mm, leaving 25mm clearance on each side for valve connections.
Q: Will a 300mm wide towel rail fit into a 300mm wall gap?
A: The rail body is 300mm, but you need slightly more clear wall space for valve connections. Allow 350mm minimum — 300mm for the body plus approximately 25mm either side for 15mm compression valve connections.
Q: Is the 400×300mm model sufficient as a dedicated hand towel rail in a cloakroom?
A: Yes — with the right expectations. At ΔT50 it produces 337 BTU / 99W, which is supplementary warmth, not a primary heat source. It will keep a hand towel warm when the central heating is running. Fit a Dual Fuel Kit for year-round warm towels independently of the boiler.
