About Concrete Sinks

Concrete sinks are a distinctive choice for homes and businesses, since most buildings don't have them. They are attractive and often are custom-made. All three common types of sinks--pedestal, vessel and integral--are available in concrete. They can easily be installed as part of a concrete counter top.

Types

Concrete sinks can be custom-made or ordered in pre-cast designs. They come in a wide variety of styles, including drop-in, undermount and farmhouse-style (apron-front), which are built into the counter with the front panel left open to view. Many contractors like to install the sinks along with concrete counter tops for a seamless look. Concrete sinks typically are more expensive than those of other materials, particularly when customized.

Significance

Since concrete sinks can be handmade and hand-finished, customization is possible. Unique bowl shapes and sizes, double bowls, sinks with an antique look, built-in drain boards and sinks of any color are all possible with concrete. Also, even with pre-cast designs, every one will be different, because concrete is a mixture of many different materials, creating variations in color, texture and general appearance. Because of the customization possibilities, concrete can enhance any kitchen style, from rustic to traditional to modern.

Considerations

Concrete sinks are susceptible to small tight hairline cracks that can appear within months of installation. A crack usually occurs because of subtle seasonal or geological movements of cabinets and shifting of the entire building structure. Contractors and designers encourage buyers to view a hairline crack as aesthetically pleasing rather than a defect. If a large crack occurs, it should be covered by the warranty.

Effects

Concrete sinks must be sealed with a high-performance and exceptionally durable sealant to prevent staining. A high-quality sealant will not need reapplication for many years. Some types of food may cause a light stain on the sealant if not cleaned up immediately. Any stain can be removed by sanding it out and resealing that area.

Prevention/Solution

People should not place hot pans in the sink or do any cutting on the concrete. The sealant can be scratched with a knife or other sharp object, although this can easily be repaired by applying sealant over the scratch. It is important to repair scratches right away because they can allow food to seep onto the concrete and cause staining.
