Great quality at an unbelievable price!

During our kitchen remodel we needed to replace an old top-mount cast iron/porcelain triple bowl sink. Due to a multitude of factors, stainless steel under-mount became our only option, with prices ranging from $1,200 to over $2,000. We were so skeptical when we found this MR Direct sink at its low cost that we ordered it early in order to inspect it for problems, expecting to send it back. However, it appeared perfect, and 2 months later it is performing flawlessly! This is a GREAT sink that we expect to last for many, many years!

Excellent Company

I received my order and the original sink had a bent edge. Contacted them by email and received very prompt and excellent service. Received my replacement and it was perfect. Would recommend this company to friends and family. East and wonderful to work with.

Triple sink

Love it!!. This is my 3rd triple sink in my 3rd house & the best one I've purchased with the least amount I paid for. The men who installed my granite commented how impressed they weee of the triple sink. Who needs a dishwasher when they have this. Thank you Mr Direct sinks. Love it.

Awesome Sink!

Ordering online at such a great price, I was concerned about the quality. What a great surprise! This is by far the best kitchen sink we've ever had. Exceeded our expectations.
