When planning a new kitchen, one of the key choices is what type of sink you install. Granite sinks and synthetic sinks are two of the most popular options, each offering distinct advantages. 


Granite sinks are made from natural stone mixed with resin, giving them a premium, solid feel and a finish that looks at home in both modern and traditional kitchens. They are known for their resistance to heat, scratches, and stains, making them a reliable long-term choice.


Synthetic sinks, often made from durable composite materials, provide a different set of benefits. They are typically lighter, come in a wider range of colours, and can be easier to install. Many homeowners prefer synthetic sinks for their versatility and affordability, without compromising on durability. By comparing these two types, you can decide which best matches the style and practicality your kitchen needs.

Frequently Asked Questions

What is the difference between a granite sink and a synthetic sink?

Granite sinks are made from a composite of crushed stone and resin, giving a natural stone look with high durability. Synthetic sinks, such as Tectonite, are made from glass fibre–reinforced polyester, offering strength with a lighter, acrylic-like feel.

Which sink is more durable: granite or synthetic?

Both are durable, but granite composite sinks are harder and more resistant to heat, scratches, and stains. Synthetic sinks are tough but slightly less resistant to extreme heat or sharp impacts.

Do synthetic sinks look like plastic?

No. While they have a smoother, acrylic-like finish, synthetic sinks are reinforced with glass fibre, making them stronger and more stylish than plastic alternatives.
