Stone Design Concepts has the same owners as Phoenix Homes. We had a granite counter top installed when we bought a townhouse from Phoenix and it was great so we decided to get a granite countertop for the vanity in the master bathroom when we moved.
We took advantage of the show special about a year ago and are very happy with the outcome! Their design centre consultant was excellent, we got to see and OK the slab before they cut it and their installers were right on time and did a good job. They use computerized lasers to measure the countertop's size so it was a perfect fit. They also offered a free sink and side/backsplash included in the price. However, we asked them to install a different sink that we ordered ourselves and they were very happy to do that for us as well. All in all, while this is not a "true" granite/quartz warehouse, if you like one of the dozen granite and quartz styles that are included in the show special they are good quality and a great deal! Highly recommended!
