300mm Wide Chrome Towel Rails | 250mm Pipe Centre| 250mm Pipe Centre
14 years supplying UK bathrooms, est. February 2012. Free delivery on orders over £200. 5-year manufacturer's warranty on all towel rails.
The 300mm chrome towel rail was engineered for one of the most common constraints in UK bathroom design: the narrow alcove between a vanity unit and a shower screen. At exactly 300mm wide with a 250mm pipe centre, it matches the most common legacy bathroom pipework spacing — a direct swap-out with zero additional drilling. Scaling from a compact 7-bar 400mm unit to a 31-bar 1800mm feature piece, it covers everything from cloakroom supplementary heat to full ensuite primary source. Central heating, electric, and dual-fuel; 5-year warranty.
Pipe Centre Note: When installing a 300mm wide chrome towel rail on central heating, your pipework should be set at 250mm centre-to-centre for straight floor-entry valves. For wall-emerging pipework, use angled or corner valve offsets.

Why Choose a 300mm Width Towel Rail?
The 300mm width sits at the boundary between the narrow and standard ranges. It fits the gap beside a shower enclosure or between a freestanding vanity and the nearest wall — spaces typically 280-350mm wide. The bracket span is roughly 170mm (65mm inset each side), so the wall footprint is considerably smaller than the overall width. It projects 90-110mm from the wall — rarely a problem in a standard ensuite layout.
- Ideal Room Suitability: Compact ensuites (2-4 m2), shower rooms, narrow alcoves between vanity units and shower screens, slim stud-wall recesses, and loft ensuite bathrooms where wall space is limited.
- Towel Drying Capacity & Ergonomics: A bath towel folded to approximately 250mm width hangs flat with no overhang. Two hand towels dry simultaneously on different bar sections. At 1000mm+ heights, a full bath sheet folded in half lengthways fits across multiple bar pairs.
- Installation & Wall Space Considerations: The 250mm pipe centre matches a large proportion of UK legacy installations — direct swap for older 300mm rails without moving pipework. Total wall clearance approximately 400mm. Use angled valves if pipes emerge from the wall.

Key Installation & Accessory Compatibility
- Pipe Centre Alignment: Fixed at 250mm across all heights in this width range.
- Required Valve Hardware: Pair with our Chrome Radiator Valves — straight valves for floor pipework or angled/corner valves for wall pipework.
- Dual Fuel Conversion: Use your rail in summer with a Dual Fuel Kit and Heating Element.
Understanding the ΔT30 / ΔT50 / ΔT60 Output Columns
The three output columns in the table above correspond to different heating system types. ΔT50 is the UK standard (BS EN 442) used by most gas boilers; ΔT30 applies to heat pump systems running at lower flow temperatures; ΔT60 applies to older high-temperature gravity-fed systems. For a full explanation of how these figures work, how to match them to your system, and how to calculate the exact BTU your room needs, see our Towel Rail Heat Output & BTU Calculator Guide.
Frequently Asked Questions
Q: What is the pipe centre for a 300mm towel rail?
A: The standard pipe centre for a 300mm wide chrome towel rail is 250mm, leaving 25mm clearance on each side for valve connections.
Q: Can a 300mm wide towel rail act as the sole heat source in a small ensuite?
A: Yes, with correct sizing. A typical ensuite of 4-6 m2 needs approximately 400-700 BTU at DT50. The 600mm height delivers 522 BTU / 153W — sufficient for a well-insulated ensuite. For higher heat loss, choose 800mm or 1000mm. For heat pump systems, use the DT30 values.
Q: Will a 300mm chrome towel rail fit between a vanity unit and a shower screen?
A: In most cases yes — provided the gap is at least 400mm wide (300mm rail + 50mm valve clearance each side). Straight floor-standing valves are the slimmest option; angled valves suit wall-exit pipes.
