A kitchen sink is a large sanitary fitting installed in a kitchen worktop and used for washing food, dishes and utensils. UK sinks are available in single bowl, one and a half bowl and double bowl formats, in stainless steel, composite granite, ceramic or enamelled steel finishes. Installation must comply with Building Regulations Part H1, with a 40mm waste pipe and trap conveying flows to an external gully or soil stack. Sinks are normally fitted into a worktop on a kitchen base unit, sealed with silicone to prevent water ingress. Modern designs include integral drainers, accessory channels and waste disposal units. Replacement during kitchen refurbishment in London flats often requires careful coordination with worktop suppliers and trap fittings to maintain compliance with minimum gradients and seal depths.
