We are so impressed by this place. Although they have more limited stone options especially when…read moreyou look at the front showroom where a lot of the stone says sold out, we found a stone design that worked well for our kitchen renovation project by looking at the larger stone slabs in the back. Since we came with a diagram and measurements of the slabs ready, we received a quote on the spot, and we were shocked that the quote was about half the price of a nearby competitor and a fraction of the price of estimates for stone and installation online. They were very accommodating and super helpful generally. Once we paid for the stone in person a few weeks later, we went to the back to choose the 3 slabs. They were helpful in telling us which slabs might not be as nice considering we wanted smaller patterns. Then on the day of our kitchen renovation, the men who came to cut and sand the stone in our kitchen and took the whole day. They were really careful and made sure it fit perfectly. It was messy but that's all part of the renovation project. Grateful we found them!

From start to end I had a good experience with US Superior Stone and Tile. The TLDR/most important…read moretakeaways are: make your order in person and be assertive about asking for help rather than waiting for staff to come to you First, I visited every place that sold countertop and tile in the east Bay Area. USSS&T had the best prices by a significant amount. I looked at all their options, got quotes, and went home to think about it. I ended up returning in person to place my order, and I STRONGLY recommend anybody who wants to place an order do so in person. Most of the staff do not seem to have English as their first language so a miscommunication might be more likely to happen over the phone. Also, when I picked the stone I wanted for my countertop, they actually allowed me into the warehouse area where I was permitted to pick which slab I wanted of the ones available. That's not an experience most places will offer. They helped us load the tile into our car and we scheduled a time for them to install the countertop. Brief note that I emailed them about making an order the same morning that I decided to go in person, and they took over two weeks to reply to my email. So again, ORDER IN PERSON. They arrived at the time they'd said they would. I will say they told me they'd arrive "after 1pm", and the day of installation around 11am I got a call from USSS&T saying the installation guys would actually be arriving an hour early, at noon. They ended up arriving at 1pm anyways. So they got right down to business, very efficient and polite, made sure to check in with me and my contractor at each step. The whole thing was done in about 1.5 hours. I really recommend them. I also want to note that some other reviews mention the staff members seem unenthusiastic or rude. There's obviously a cultural difference here. The staff members were never rude or anything to me, they were very professional. If you want help at the store you can't just wait around hoping for somebody to approach you. You have to go up to a staff member and ASK to be helped. At this point they are happy to help and will be very efficient. They are also all knowledgable so no matter who you get to help you they'll be able to answer any question you have.

We initially discovered US superior in preparation for a remodel in 2023. We were reassured by…read moreseveral recommendations from other contractors that they offered a quality product. Randi Siu is my point of contact and was very accommodating and patient despite some project delay. We kitchen Cabinets upper and mowers along with vanities for two bathrooms.

Ultimately we decided to have US Superior perform the install as well. We could not be more impressed with the service from start to finish. Fast forward to 2026, we had a couple cabinet repairs to be addressed. I called them out fully expecting to pay for any repairs. Randi sent their team out to address the issues which took all of an hour, if that. To my surprise there was no charge. I truly appreciate US Superior for not only delivering a great product but standing behind it!

Many years ago we ended up finding the perfect quartz slabs from Artistic stone. I recall the…read moreservice was mediocre, but no major issues (I recall they had recommended that the slab seam be located in the middle of the countertop, until I requested the seam be behind the sink faucet). Fast forward to 2025 and I reached out for a quote and Benjamin responded via email within 24 hours. He was so responsive so we decided to pop by to take a look at their inventory. They have a great selection of slabs and prefab stones and Benjamin was very knowledgeable, answered all of my questions, and had an eye for detail. Our project is very simple and straightforward, but the prices were reasonable and I am so excited for the stone we chose!

We walk in and no acknowledging from the Asian and Caucasian ladies at the desk. Fine, I'm pretty self sufficient. Time goes by and nothing. My son decides to pick up one of the little grout samples and the Asian lady says, "Kids, let's not touch." I took that as an opportunity to ask questions and I got short and condescending answers. In that moment, I knew my pregnant self was going to blow so I grabbed my kids and decided to skiddaddle. Unfortunately for them, a Caucasian lady happened to walk in and was immediately acknowledged. I couldn't stay silent. I marched right up to the lady at the desk and asked why I wasn't helped until my child touched something. She said, "I'm sorry" and pointed at her computer. Absolutely ridiculous/discriminatory customer service. I will never come back here. So much for their vision, "OUR VISION A TEAM dedicated to creating the BEST VALUE for OUR CUSTOMERS through INNOVATIVE PRODUCTS and EXCEPTIONAL CUSTOMER SERVICE"
