The brushed stainless steel kettle and toaster come in an array of glossy colours, which Sunbeam said deliver "an unrivalled sensory experience".
Both products in the Sunbeam Marc Newson range feature rounded edges and circular controls, and have been designed to be "classic and futuristic".
"It made perfect sense for me to become involved not only from the perspective of a designer but also as a consumer," the London-based designer added.
The toaster has a flat stainless steel top, brightly coloured tapered sides and an extra-wide crumb tray.
The flat-topped kettle features a round body, resting on a circular black base, and an arched handle. A coloured section covers the top of the appliance, which has a seal construction to make sure steam doesn't escape.
The kettle is turned on and off by a semi-circular tab-shaped button at the base of the appliance.
Both designs can be ordered the collection in green, blue, orange, yellow, black, red or white versions.
"My aim with the Sunbeam Marc Newson range was to create something that was simultaneously classic and futuristic," said Newson.
Earlier this year, Naoto Fukasawa designed a range of minimal kitchenware for Muji that also included a kettle and toaster.
Newson, who is now part of Apple's design team, has worked on several collaborations this year, including a partnership with German brand Montblanc to create a range of pens featuring nibs plated with rare metals.
He stirred debate in Dezeen's comment section after incorporating mammoth-ivory handles in an £82,000 limited edition tea set for Danish metalware brand Georg Jensen.
