350mm Wide White Towel Rails
The 350mm wide white towel rail sits in the productive gap between narrow compact and standard family-bathroom widths — offering 50mm more rung surface than our 300mm range (meaningful for hanging folded towels), without protruding 50mm further into the room like a 400mm would. With a 300mm pipe centre, it drops directly into most existing rough-in installations originally fitted for a 350mm panel radiator, making it a natural upgrade path for compact ensuite renovations. The highest output in the range — 2,421 BTU / 710W at 1800mm — qualifies it as the primary heat source for ensuites up to 16m² on a standard boiler.
Pipe Centre Note: When installing a 350mm wide white towel rail on central heating, your pipework should be set at 300mm centre-to-centre for straight floor-entry valves. For wall-emerging pipework, factor in angled or corner valve offsets.

Why Choose a 350mm Width Towel Rail?
The 350mm sits between the narrowest narrow and the standard 400mm — it works where 400mm is 50mm too wide for the alcove, the tiled reveal, or the gap between a doorframe and vanity unit. Because the pipe centre is 300mm (not 350mm), it’s also the natural first choice when replacing a 350mm-wide panel radiator without moving pipework.
- Ideal Room Suitability: Compact ensuites (4–10m²), narrow alcoves between vanity units and shower screens, and renovation projects replacing 350mm panel radiators with the same rough-in position.
- Towel Drying Capacity & Ergonomics: A standard UK bath towel (70cm wide) folds once to 35cm, laying flat across the 350mm rungs with 5mm of rung spare each side. Bath sheets (90cm wide) fold to 45cm — slightly wider than the rung, but they drape well and warm evenly across the bars.
- Installation & Wall Space Considerations: Allow 420mm of clear wall space minimum. The 300mm pipe centre matches many existing 350mm panel radiator rough-ins, but confirm before removing the old radiator — some 350mm panels use a 300mm or 320mm pipe centre that will require minor pipework adjustment.

Key Installation & Accessory Compatibility
- Pipe Centre Alignment: Fixed at 300mm 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 350mm white towel rail?
A: The standard pipe centre for a 350mm wide white towel rail is 300mm, leaving 25mm clearance on each side for valve connections.
Q: Will a standard UK bath towel hang flat on a 350mm towel rail?
A: A standard UK bath towel (typically 70cm wide when unfolded) needs to be folded in half lengthways to approximately 35cm. At 350mm of rung width, the towel fits flat with 5mm of rung each side. For bath sheets (90cm wide), fold to 45cm — the towel will drape over the edges slightly but warm and dry effectively.
Q: Can I replace a 350mm-wide panel radiator with a 350mm white towel rail using the same pipework?
A: If your panel radiator has a 300mm pipe centre (standard for most 350mm-wide panels), yes — the 350mm white towel rail connects directly. If the existing pipe centre is 320mm or 325mm (found on some older panels), you will need minor pipework adjustment of 10–15mm per side.
