Granite Composite Sink Buyer’s Guide

Granite sinks are becoming more and more popular, but is it the right choice for you?

In this section, we’ll go over the basics of granite composite sinks and answer some common questions.

What are Granite Composite Sinks Made Out Of?

Granite composite sinks are made by mixing fine granite sand with an acrylic resin bonding agent. Most manufacturers use a mix of 80% granite particles and 20% bonding agent.

This process produces a material with many of the same qualities of granite while offering better durability and easier maintenance. Granite sinks are also much relatively affordable.

Some kitchen sink manufacturers produce granite composite sinks under trade names like Blanco’s Silgranit or Franke’s Fragranite.

Granite is the most common materials used in composite sinks, although you will also find composite sinks made from quartz. This article focuses on granite sinks, but much of the information applies to quartz sinks as well.

Appearance of Granite Composite Sinks

Unlike natural granite, granite composite sinks have a very uniform color and still retain the warmth and charm of real stone.

Granite composite kitchen sinks have a beautiful “sandy” look that works well with many decors. Most composite sinks will have a lightly textured matte finish.

Granite composite has excellent heat resistance. Most manufacturers rate their granite sinks to just over 530 °F (about 276 °C).

Small chips and cracks may occur from heavy impacts. In many cases, light damage can be repaired with an epoxy filler tinted to match the sink.

Granite composite is a very tough material, but it might be worth investing in a stainless steel bottom grid for extra protection.

Maintenance and Cleaning Granite Composite Sinks

Unlike solid granite, granite composite is nonporous, making it easier to clean and maintain.

Most stains and messes can be cleaned using gentle cleaners and soft scouring pads or microfiber cloths. Don’t use steel wool and wire brushes.

Bar Keeper’s Friend and Soft Scrub are recommended by several manufacturers as strong but safe cleaners for granite composite sinks.

Wiping the sink dry after every use will help avoid stains or mineral buildup.

Many granite kitchen sinks will also benefit from an occasional application of mineral oil. This is especially helpful with darker color sinks when it comes to maintaining deep blacks and browns.

While composite sink maintenance is fairly straightforward, some cleaners can mar the surface of granite composite sinks. Always be sure to carefully read the manufacturer’s care and cleaning instructions that are included with your sink.

Granite Sink Cost

Most granite sinks will range in price from $200 to $400. This is relatively affordable compared to other premium sinks options like cast iron or fireclay.

Of course, cost can vary greatly depending on size, mounting style, and basin configuration. Undermount and apron front (farmhouse) sinks will tend to be more expensive. has an excellent article on composite sink prices.

Granite Composite Sink Noise

Granite composite has great sound-absorbing properties. Compared to other kitchen sink materials, granite sinks are very quiet.

Running water and placing dishes in the sink will create significantly less noise than a stainless steel sink.

Granite Sink Installation

Installing a granite composite sink isn’t particularly difficult. However, keep in mind that they’re a lot heavier than stainless steel. Granite sinks may require additional structural support below your counter.

If you’re not sure if your counter can handle the additional weight of a composite sink, it’s best to hire a contractor for the job.
