850mm Wide Chrome Towel Rails| 800mm 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 850mm chrome towel rail fills the space between the 800mm and 900mm ranges — purpose-built for the large master bathroom or wet room where existing pipework sits at exactly 800mm centres. With an 850mm bar span and three heights from 600mm to 1000mm delivering up to 1,368 BTU at standard boiler temperatures, it provides confident primary heating and expansive towel-drying capacity. The nearly-metre-wide polished chrome surface creates a striking focal point in premium bathroom designs. Central heating, electric, and dual-fuel; 5-year warranty.
Pipe Centre Note: When installing a 850mm wide chrome towel rail on central heating, your pipework should be set at 800mm centre-to-centre for straight floor-entry valves. For wall-emerging pipework, use angled or corner valve offsets.

Why Choose a 850mm Width Towel Rail?
The 850mm width suits bathrooms where the wall section available is 850-950mm and the plumbing is at 800mm centres. At this span, the chrome surface becomes the dominant element on the wall, and installation height from the floor (typically 350-450mm) matters as much as technical sizing.
- Ideal Room Suitability: Premium master bathrooms (12-18 m2), wet rooms with wide pipe spacings, and design-led bathroom refurbishments where the towel rail is specifically specified as the centrepiece.
- Towel Drying Capacity & Ergonomics: Two full bath towels and one hand towel can all hang simultaneously without touching. The 850mm bar span is wide enough that a bath sheet lays entirely flat from side to side.
- Installation & Wall Space Considerations: The 800mm pipe centre requires confirmed pipework positioning before ordering. Allow approximately 950mm total wall clearance. Only three heights are available (600mm, 800mm, 1000mm) — select based on BTU requirement.

- 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 850mm towel rail?
A: The standard pipe centre for a 850mm wide chrome towel rail is 800mm, leaving 25mm clearance on each side for valve connections.
Q: Why choose an 850mm chrome towel rail over an 800mm or 900mm?
A: The 850mm is the direct match for bathrooms with existing pipework at 800mm pipe centres. If your pipes are set at 800mm, an 850mm rail installs without any plumbing adjustment. An 800mm rail uses 750mm centres; a 900mm uses 850mm centres — ordering either when your pipes are at 800mm means the valve ports won't align.
Q: How many heights are available in the 850mm chrome towel rail range?
A: The 850mm chrome range is available in three heights: 600mm (798 BTU / 234W at DT50), 800mm (1,082 BTU / 317W), and 1000mm (1,368 BTU / 401W). For rooms needing higher output, the 900mm width extends to additional heights.
