I was in the market for new kitchen countertops and a home-remodeling supply store I visited recommended Cosmos. She said it would be helpful to see the big slabs of various materials at Cosmos rather than the tiny little samples that most places have. She was totally right and this place is perfect. There was plenty of parking and the signs were helpful to pint visitors in the right direction for the showroom. I was greeted as soon as I walked in and the whole process was explained. I was given a clipboard to take notes of my favorite materials. I was also given a quick tour of how everything was organized and to stay within the yellow lines. She also showed me where a customer lounge was located complete with complimentary coffee. I also appreciated the colored stickers to show estimated price ranges. It was great to take photos and notes on what I liked. It sure was hot in the warehouse though!! It was good to slip back into the AC in the customer lounge to cool off. I definitely recommend Cosmos if you're trying to decide on kitchen or bathroom countertops. read more

We were sent here by our contractor. They have a very large selection of quartz, marble and granite. You are able to walk through the warehouse and hand select your choice of counter top. All options are clearly marked with all the information you need. Friendly service provided as well by the staff here. read more

After dealing with a mistake by a competitor we found the perfect slab for our master bathroom. Everybody was very helpful and accommodating. We will be back when we remodel our kitchen. read more

Really nice staff. Enormous warehouse of granite and quartz slabs. I do wish the lighting were a little better. I can't comment on pricing because they only sell to fabricators so while, as the customer, you can go in and shop and write down your selections, you won't know how much it is until you personally hire a fabricator. read more

We've bought granite from Cosmos several times, and they are the first place we look. They are solely a granite wholesaler, so you need to also have a fabricator. Cosmos has a huge indoor warehouse, plus more outside, with the best selection in Raleigh. Prices seem competitive, but you need to discuss pricing with your fabricator as they don't discuss it with the customer. Granite comes in several general price "levels", so you can get an idea of how expensive they will be. The staff is always very helpful, and they will move slabs for you to preview and hand-pick, which some places don't do. Cosmos is open on Saturday, but will only move slabs M - F until 4:30. Due to the heavy stone and warehouse environment, this is not the best environment for children. read more

We had a good experience at Cosmos. Other than the fact that the staff ignored us and our contractor, the gentleman in the warehouse was great. Almost too many choices. One note of advice: Wear comfortable shoes. You will be doing a lot of walking. Pros: Choices Cons: Reception read more

Cosmos is great! Excellent and vast selection of quality stones. The variety is impressive! You can find common stones, super exotic interesting slabs and everything in between. The staff was very knowledgeable and helpful too! read more

Great service and worked seamlessly with our fabricator. The only downside was we had to go during the week to choose our slabs as they cannot move slabs on the weekends. read more

This is speaking directly to the Greensboro location, which is the only location I have interacted with. They have a beautiful selection of slabs, and the warehouse is clean. If we were working on that alone, they'd get a great review. Even in person, the staff is fine to deal with, but on the phone, they lack basic knowledge about their products, and are exceptionally rude and unhelpful in answering basic questions to understand various types of products that they have on hand. The woman I spoke with didn't even know one of the materials was, and actually had to look it up, and then when I asked about cleaning, she put me on hold and then returned to tell me curtly "You're going to have to call your fabricator". Look dear, the fabricator doesn't have a giant warehouse of this stuff, you do, and from their own website's about us section, it claims that: "Professional, educated staff to help you make the most knowledgeable choices in your selection." No, this was certainly not my experience. Cosmos Greensboro, I actually DID call my fabricator, and I'll be getting my product elsewhere. There are suppliers speckled across the Triangle and Triad like butterflies. This is too competitive of a field for you to lack in this arena. read more
