A premium matt textured grey vertical designer radiator (also known as anthracite) delivering 3,733 BTU from a slim 490mm body. 1800mm height, single panel construction, 52mm depth, 23.19kg. 5 year Kartell UK manufacturer guarantee. All fixings included.
The most popular full-height designer radiator in the anthracite Boston range, the Kartell K-Rad Boston 1800 x 490mm Anthracite Vertical Single Designer Radiator is the size most customers pick when they want a striking floor-to-ceiling design feature with serious heat output. The 490mm body delivers 3,733 BTU (1,094W) from a slim 52mm profile. The matt textured grey finish makes a real visual statement in modern living spaces. SKU: BOS1800-480A.
At 1800mm tall and 490mm wide, this is the most-chosen full-height Boston in anthracite — the size most customers pick for living rooms, hallways and modern open-plan spaces.
The 8-tube single panel delivers enough heat for typical UK living rooms up to 16m² with average insulation — the natural choice when you want one striking radiator to do the job of two horizontals.
The matt textured grey powder coat is durable, scratch-resistant and brings serious designer character to modern living rooms, hallways and open-plan kitchen-diners.
Despite the dramatic full-height proportions, the single panel construction sits just 52mm from the wall — preserving floor space and keeping the room looking open.
Identical dimensions to the white BOS1800-480W means you can run anthracite in main living spaces and white in bedrooms while keeping a unified designer language throughout the property.
Full coverage on the genuine 5 year guarantee — registered direct with Kartell UK in your name. This is the original Kartell-branded Boston, not a re-branded copy.
