Introduction
“Masterpiece of Stone Precision and Timeless Stair Elegance”
Stair treads are a key architectural detail that combines safety, durability, and design. At Granite Depot, we fabricate and install custom stone stair treads that enhance both residential and commercial spaces across East Tennessee.
We offer granite, quartzite, and natural stone options that deliver long-lasting strength while adding a refined, seamless look to staircases, entryways, and custom architectural features.
Each project is designed to match your space with precision and attention to detail.
FABRICATION
Precision-Cut for Perfect Fit
Stone stair treads require precise fabrication to ensure consistent dimensions, safety, and structural accuracy.
Our team carefully cuts, shapes, and finishes each tread using professional stone fabrication equipment. We focus on edge quality, surface smoothness, and exact sizing to ensure every piece fits perfectly within your staircase design.
All materials are selected for durability, slip resistance, and long-term performance in high-traffic areas.
INSTALLATION
Safety, Alignment, and Stability
Proper installation is essential for safe and long-lasting stair treads.
Our installation team ensures each stone tread is securely set, levelled, and aligned for consistent step height and structural integrity. We also ensure proper bonding and finishing for both indoor and outdoor applications.
From residential staircases to large-scale architectural projects, we deliver installations built for strength, safety, and elegance.

“I cannot say enough about Granite Depot of Sevierville and Adrian. I was in a bind needing a quick install and he went above and beyond to make sure that I got the stone that I wanted and had it installed in the time that I needed very professional and always kept me informed of what was going on. It was not a huge job, but they treated me just like if it were a huge job they had me installed in seven days. Highly Recommend Adrian and the Granite depot.”

FAQ
What is natural stone?
Natural stone refers to a number of products quarried from the earth that have been used over many thousands of years as building materials and decorative enhancements. These products include granite, marble, limestone, travertine, slate, quartzite, sandstone, adoquin, onyx, and more. They are more than just rocks. Natural stone is hand selected from the best, most consistent sources for durability and beauty.
Natural stone products differ in composition, color, and texture even among pieces from the same source. This is usually considered a benefit, lending itself to one-of-a-kind designs and distinctive, dramatic applications. Give us a call today at Granite Depot to pick out a natural stone for your kitchen remodel in East Tennessee.
Why should I use natural stone in my home?
Natural stone is prized for its distinctive beauty and the sense of peaceful tranquility it creates, but there are also many practical benefits to using natural stone in your home. Natural stone products are more durable than many artificial products, often lasting for decades with very little maintenance. With natural stone, there are no worries about exposure to harmful chemicals in the home or released into the environment during production or disposal. Why invest time and money into a look-alike? Natural stone, such as marble countertops in Knoxville, Johnson City, Sevierville and the surrounding East TN areas, are the real thing that artificial products try to emulate.
Why is granite preferred for kitchen and bar countertops?
Granite is the hardest and densest of all natural stones. The feldspar content keeps it water resistant, and the silicates it contains won’t react with acid. These properties help granite resist staining and retain its fine luster over a longer period of time than ceramic tiles or other stones.
Although marble is commonly requested for countertops in bars and kitchens, marble’s high carbonate content makes it vulnerable to acidic substances. That’s why our granite counter tops in Knoxville, Johnson City, Sevierville and the surrounding East TN areas are so popular.
What care and maintenance are recommended for stone products?
Stone surfaces are very easy to maintain. Clean countertops with warm water and mild liquid soap. Never use acid cleansers or abrasive chemicals on stone. Natural stone should be sealed after installation. Give us a call if you have any questions about sealer for your granite, marble or quartz countertops in Knoxville, Johnson City, Sevierville or the surrounding East TN areas.
Why does granite need to be sealed?
All natural stones, including marble and granite, must be properly sealed to protect against staining. Without proper and regular sealing, granite counter tops and other natural porous stones can absorb spilled substances, leaving unsightly stains and marks. Give us a call if you have any questions about sealer for your granite, marble or quartz countertops in Knoxville, Johnson City, Sevierville and the surrounding East TN areas.
What is an impregnator sealer? How does it help stone?
Impregnator sealer consists of microscopic balls of silicone that attach themselves to crevices inside the stone. These balls become a permanent part of the stone and act as a waterproof shield. Give us a call if you have any questions about impregnator sealer for your granite counter tops in Knoxville, Johnson City, Sevierville and the surrounding East TN areas.
