I recently remodeled my kitchen and needed all new countertops and a new island. I had visited six stores in the surrounding Philadelphia area and united granite and marble had the largest selection by far. They have a large warehouse in King of Prussia where you can see the entire slabs. Some places only have very small samples and frankly when you are spending that amount of money you really don't want to buy countertops by just looking at a 4 x 6 piece sample. Sara's Customer service was fantastic. She was extremely knowledgeable and went above and beyond to help with scheduling to remove my existing countertops and to template and install my new quartz countertop and island. I am thrilled with the results. I would highly recommend Sara and United granite and marble. Tina read more

Absolutely LOVE my new quartz countertops installed by United Granite's Dave Tressler and his guys. Dave was awesome! He came out right away for an estimate and did a VERY thorough job measuring everything, taking notes, and giving tips on what needed to be done ahead of time. He was super professional. Dave and the crew installed it a few days after our initial meeting and I couldn't be happier! The Calcutta Verona stone looks amazing and makes the whole kitchen seem new again. It brightens up the whole space! I would definitely recommend United Granite and Dave! A big THANK YOU to him, his guys, and Henry (the owner)! read more

Needed a small quartz remnant for a bathroom remodel. I worked with Sara out of the KOP office who was very kind and responsive to our needs and many questions! I also worked with Henry from the Fab in Colmar, PA. He was very friendly and actually caught an issue in my 'final' plans prior to cutting and called to confirm/correct! The quality of the quartz remnant was excellent, all measurements were precise and the finished job looks amazing in our bathroom! I absolutely will do business again with them in the future. Currently typing this in my outdated kitchen :) Thanks United Granite! read more

Our contractor gave multiple recommendations on Granite Providers, but after visiting a couple of the other vendors (not impressed) and then visiting United Granite meeting Sara and the other employees I was impressed by their knowledge of the products and providing assistance or answers to my questions. Sara was my salesperson and was wonderful and informative as well as a pleasure to work with. The delivery was quite impressive to watch. The gentlemen that delivered and installed the granite were detailed oriented. I want to say thank you to all involved and my special thanks to Sara. read more

Couldn't be more pleased with my experience in the warehouse, installation, and how amanzing my kitchen looks after installation. Everyone working there is super helpful. They have the absolute best selection compared to every other location I went to. They have top of the line material. You pay for what you get. Stunning slabs and amazing workers. I will be using them for all future products. My countertops sell my kitchen and are the statement when I have guest over. They alone sell the review and already had people interested in United Granite after seeing my kitchen. read more

Best countertop selection around!! We renovated out kitchen in 2021. We went to so many fabricators and show rooms (approx. 9-11) before finding United Granite. This renovation was a once in a lifetime project and I did not want to settle with anything for our countertops. The selection United Granite has is fantastic. The installers were amazing! They did a fantastic job with the installation and color matching the seams. I would highly recommend, and I know this is where I will be headed when we renovate our bathroom! read more

We had a very smooth and pleasant experience buying our countertop from United Granite. Katya was very organized and responsive and made us feel comfortable during the whole process. On the day of the install, they were quite delayed, but they kept us updated throughout the day and even though it was late by the time they got to our place, they couldn't have been more pleasant or professional. I would recommend United Granite to anyone that's shopping for a countertop! I'm really glad we went with them. read more

Waited 40 years to get my kitchen renovated. From laminate butcher block to fantasy brown quartzite. From start to finish everything was great. Template technician arrived when they said, answered all my questions and went over every detail in the autocad. Afterwards went in for layout. Installers arrived on time for my counters and the full height backsplash and they were gentlemen. Pieces were cut exactly to the layout, grain flow and patterns matched perfectly. Thank you all for doing a great job. read more

Sam and the crew at United Granite did a great job on my kitchen! We didn't know what to expect never having spent this much on a home remodel before, but Sam worked with our design and after going through the HUGE INVENTORY we landed on an amazing marble. Noder(?) and the install crew were great, and they took great care with our house! Will definitely be recommending them to friends and family, they are truly a gem of the area! read more

United Granite was absolutely wonderful to work with. Henry was so accommodating and thorough. The crew was out to measure and within a few days, the granite was installed. When picking out the slab, Henry was so helpful and patient. I love walking into my kitchen everyday and seeing my beautiful granite!! I would definitely recommend United Granite to all my family and friends! read more

They had an amazing selection of slabs of all types. Everyone there was so incredibly knowledgable, capable, thoughtful, and helpful. Their prices were competitive and our final product (countertops) look even better than we could have imagined! They did everything they said and they did it exactly as they said they would. Fantastic company, would recommend 10/10 read more

Great experience working with this company. Gorgeous slabs to choose from, competitive pricing, quick turn around time and very professional. I had my heart set on a sink that needed a custom cut out, another company told me couldn't be done but United had no problem.
