Composite sinks earn their name because they are composed of a combination of natural stone and resin. The natural stone gives them a lot of the durability qualities seen in materials like granite, marble and quartz, and the resin makes them cheaper than all-stone materials.
Composite sinks are very durable due to the natural stone in their makeup. They are hard to scratch or scuff, though they are more prone to these sort of problems than real natural stone. Composite sinks have no problem with moisture or heat, so they work fine in bathrooms or kitchens.
Cost and Value
Composite sinks are among the most expensive sink material options, though they are still cheaper than real stone sinks. Since they are long-lasting, you won’t need to worry about replacements; and value is added to your home by putting in a composite sink.
Composite sinks are just about indistinguishable from the natural stone materials they are partially made from. They are hard and cold to the touch.
Repair and Maintenance
If you do happen to scratch a composite sink, you can buff it out without anyone noticing the damage. This is possible because the color exists throughout the entire countertop. The surface may dull over time and require polishing or resealing.
Durability. Quality composite granite sinks are formed under high pressure, making them nonporous, hygienic, and resistant to heat, stains, scratches, and chips. Plus, unlike natural granite, a composite granite sink surface won’t require sealing.
Variety. You’ll find a wide range of styles, sizes, shapes, finishes, and color options to complement your countertops. White, black, and brown remain the most popular color choices.
Consistency. An authentic granite stone sink features the natural variations of stone throughout the material. A composite granite sink, however, features uniform color throughout the material.
Cost. A composite granite sink generally costs less than a natural granite sink.
Durability. Harsh chemicals can damage a composite granite sink, so follow the manufacturer’s suggestions for cleaning the surface as well as products to avoid pouring into the sink. Some composite granite sinks can be damaged by heat, resulting in blemishes from melting resins, and the material does scratch. Check the manufacturer warranty and select a product designed for high heat-resistance.
Hardness. While some sink materials are more forgiving, composite granite is hard enough to break glassware when dropped onto the surface.
Color uniformity. If you want the authentic look of granite, a composite granite sink is uniform in pattern and color and doesn’t feature variations like natural granite.
Costs. Quality composite granite sinks are more costly than sink materials such as stainless steel and porcelain.
