A premium gloss white vertical designer radiator delivering 2,897 BTU from a slim 420mm body. 1600mm height, single panel construction, 52mm depth, 18.47kg. 5 year Kartell UK manufacturer guarantee. All fixings included.
If you have a hallway, kitchen or compact living room that needs a vertical radiator slim enough to fit between doorframes and kitchen units, the Kartell K-Rad Boston 1600 x 410mm White Vertical Single Designer Radiator is precisely engineered for the job. The slim 420mm body delivers a strong 2,897 BTU (849W) from a footprint that occupies almost no floor space — ideal for narrow walls, alcoves and tight spaces where horizontal radiators simply won’t fit. The gloss white finish keeps interiors looking bright and considered. SKU: BOS1600-410W.
At 2,897 BTU this radiator is the slim-width sweet spot — tall enough to be a feature, narrow enough to fit between doorframes, kitchen units and tight alcoves where wider radiators won’t go.
The 420mm body is one of the slimmest vertical designer radiators on the UK market — ideal for the narrow wall behind a door, beside a chimney breast, or between fitted units.
Despite the slim profile, the 7 flat-tube design extracts genuine warmth quickly — suitable as the sole heat source for hallways, small bedrooms and compact rooms in average UK insulation.
The premium gloss white powder coat (RAL 9003) is durable, scratch-resistant, and brightens interiors beautifully — complementing both modern and traditional decor.
Light enough for a competent DIYer to lift and bracket without assistance, while still feeling solid and substantial when fitted to the wall.
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.

Valves are not included and must be purchased separately. We recommend matching Kartell K-Design White or Chrome TRV twin packs to complement this radiator perfectly. Select your pipework type below.
When to use: Pipework rises vertically from the floor and connects to the side tappings of the radiator. This is the most common UK installation type for vertical radiators.
When to use: Pipework rises directly from the floor into the bottom tappings in a straight vertical line.
When to use: Pipework rises behind the radiator and connects to the bottom tappings at an angle, giving a clean concealed finish.

Yes — at 420mm physical width, the Boston 1600 x 410mm sits comfortably in the narrow gaps between most UK doorframes, chimney breast pillars and fitted kitchen units. Allow approximately 60–100mm extra clearance either side for valve bodies and pipework.
