Composite Kitchen Sinks

Composite sinks can use different combinations of mineral particles and binding materials, so their finish, care requirements and resistance to damage can vary. These FAQs cover what they are made from, as well as how to use them.

 

What is a composite kitchen sink made from?

Composite sinks are moulded from a blend of materials, usually mineral particles combined with resin or another binding material. The exact mixture varies between products and may include quartz, granite or other minerals.

Many granite sinks are also composites rather than being cut from solid granite. The granite name usually indicates a stone-based formulation or stone-like finish, while the wider composite category can include other mineral and resin blends.

 

Do composite kitchen sinks scratch or chip easily?

Composite sinks are designed to resist everyday scratches and marks, making them a durable choice for busy kitchens. Their blend of mineral particles and resin creates a hard-wearing surface that handles normal use well. They are not completely scratch-proof or chip-proof, however, so you should avoid dragging heavy cookware across it or dropping solid objects into the bowl.

 

Can you put hot pans or boiling water in a composite sink?

Heat resistance varies according to the sink's mineral content, resin and manufacturing process. Do not assume that every composite kitchen sink can safely take boiling water or cookware straight from the hob. To avoid any issues, avoid exposing the sink to sudden temperature changes and allow very hot cookware to cool before placing it in the bowl.

 

Does hard water mark composite sinks?

Yes. As water evaporates, calcium and other minerals can remain on the surface as pale deposits or water spots. These marks can be particularly noticeable on black and other dark composite sinks. To reduce buildup, make sure you rinse and dry your sink regularly.

 

How long should a composite sink last?

Composite sinks typically boast an impressive lifespan, often lasting up to 25 years or more. With their durability, resistance to chips and high heat tolerance, a well maintained composite kitchen sink might be the only sink you'll ever need to purchase for your kitchen.
