Kitchen Sink Wastes

Kitchen Sink Wastes Ireland – 90mm Basket Strainer Wastes, With or Without Overflow

The kitchen sink waste — what many listings call the kitchen sink drain — is the fitting in the bottom of the bowl: the basket you lift out to empty, the flange that seals against the sink, and the body underneath that the trap screws onto. Most kitchen sinks take a 90 mm basket strainer waste, so when the old one starts to weep, seizes up or no longer suits a new tap, replacing it is normally a like-for-like swap.

The wastes in this range use ELLSI's Top-Fix system. A conventional strainer waste is held by a large backnut under the sink, which means someone lying in the cupboard with a spanner. A Top-Fix waste goes in from above instead: drop it into the hole and turn the single centre screw with the supplied 14 mm tool, which pulls the pre-fitted seal tight against the underside of the sink. No silicone, no backnut and no reaching blind behind the bin.

Three Checks Before You Order a Sink Waste

• Is there an overflow? Look at the back wall of the bowl, just under the rim. A slotted or round opening there is an overflow, and it has to be connected — choose a kitchen sink waste kit with overflow, which adds the tube and a cover plate in the same finish. No opening means no overflow kit. Getting this right prevents most returns in this category.
• Is the hole 90 mm? Measure the hole in the sink, not the old flange sitting over it — a flange is always wider, and on these it is 114 mm. 90 mm is the usual cut-out for stainless steel and composite kitchen sinks.
• How thick is the sink at the hole? Top-Fix grips anything from 0.5 mm to 15 mm. Stainless steel and most inset composite sinks sit comfortably inside that range; heavy fireclay sinks may not.

32 mm or 40 mm Outlet?

A kitchen sink needs 40 mm (1 ½"). The 32 mm size is for bathroom basins, which drain less water at a time. Each waste here has a 40 mm BSP outlet that joins a standard kitchen trap. The trap itself is not included, and a sound existing one can stay — just renew its washers while it is apart.

Match the Sink Waste to Your Kitchen Tap

A sink waste is small, but it sits directly under the tap, and a bright steel plughole beneath a black or brass tap is the mismatch people notice. Choose the same finish for both:

• Chrome – the chrome kitchen sink strainer waste or the chrome waste kit with overflow, for a stainless sink and any chrome tap.
• Matt black – the black sink waste or the black waste with overflow, under our black kitchen taps or in a dark composite sink.
• Brushed brass – the brass sink waste or the gold kitchen sink waste with overflow, to pair with the brass kitchen taps.
• Antique brass – the antique brass sink waste or the antique brass waste with overflow, a darker, aged tone for traditional and Shaker-style kitchens.

On the overflow versions, both cover plates come in the strainer's finish, so the overflow matches as well.

Belfast, Butler and Double Bowl Sinks

Belfast and butler sinks are fireclay and thick at the waste hole, and many measure more than the 15 mm a Top-Fix waste can grip. Measure the edge of the hole before ordering; if yours is thicker, send us the measurement and we will tell you honestly what fits.

Double and one-and-a-half bowl sinks take one waste per bowl. Check each bowl on its own for an overflow opening and put the overflow kit only where there is one.

Changing the bathroom fittings too? Basin and bath wastes are in bathroom wastes, and our wastes guide explains which type fits where. For the rest of the sink area, browse kitchen taps or read the kitchen setup guide.
