Choosing the thickness of the worktop was identified as a key task by the Kitchen Bedroom and Bathroom Specialists Association (KBSA), with 30mm and 40mm said to be the most common but homeowners are advised to invest in the thickest material they can afford.The advantages of a laminate worktop of 40 mm or even greater thickness are said to be higher resistance to heat and damage than thinner models, while thickness is also a guard against cracks developing along the surface.And materials were also singled out for close scrutiny, with Formica often the favoured choice but other materials such as Corian sometimes used for kitchen sinks Orama and Perstopalso identified as sturdy and durable options.Colour and finish were also taken into account by the KBSA, with homeowners advised to take into account some more avant-garde choices such as gloss laminate or stainless steel.Choosing a stainless steel countertop look could help kitchen renovators to harmonise their work surface and key items like the sink, with many sinks from Franke, Astracast and other top manufacturers boasting a modern stainless steel finish.
