As of May 2015, reviews for granite kitchen sinks are available on HGTV.com and HomeDepot.com. The HGTV review considers the overall qualities of granite sinks, whereas Home Depot reviews focus on specific models.
HGTV states that granite sinks are durable, unique and attractive. Granite lends itself to a variety of designs, allowing a so-inclined home owner to match her sink to her granite countertops. However, it is sometimes difficult to find blocks of granite large enough to make very large sinks.
At Home Depot's site, positive comments about granite sinks include ease of cleaning and resistance to staining. Negative reviews cite how easily the sinks crack and break.
