(70 reviews)

Natural Grey Kota Stone is a premium limestone quarried from the Kota region of Rajasthan, India. Known for its understated elegance and exceptional durability, this natural stone features a soft blend of ash grey, bluish-grey, and subtle olive-grey tones that change beautifully under different lighting conditions. Unlike artificial flooring materials, every slab carries slight natural variations, giving each installation a distinctive and authentic character.

Its naturally textured surface provides excellent slip resistance, making it a preferred choice for outdoor and high-traffic applications. The stone remains cool under direct sunlight, making it especially suitable for patios, terraces, courtyards, walkways, gardens, and public spaces. Natural Grey Kota Stone also performs exceptionally well indoors, where its neutral color palette complements contemporary, industrial, minimalist, and traditional architectural styles.

With outstanding wear resistance, low maintenance requirements, and long service life, Natural Grey Kota Stone has become one of India's most trusted natural flooring materials for residential, commercial, and institutional projects.

Note: Depending on lighting, moisture, viewing angle, and finish, the stone may appear light grey, cool blue-grey, sage grey, or slightly greenish, creating a naturally dynamic appearance.

📐 Technical Specifications

Overview

Supreme Granite & Stones supplies premium Natural Grey Kota Stone, a top-tier Kota Stone featuring a distinct natural color tones color signature. Sourced from choice quarries in India (Rajasthan), this stone offers a beautiful blending of mineral veining and grain patterns. It is processed under strict quality controls at our Jigani yard near Bangalore to ensure that each slab displays premium consistency and structural integrity.

Heat Resistance

With its origin as a natural stone formed under high temperature and pressure, Natural Grey Kota Stone exhibits superb thermal tolerance. It does not scorch, burn, or crack when exposed to ordinary cooking heat. However, to shield the surface seal and protect the structural bonds from thermal shock, we recommend using trivets or hot pads.

Scratch Resistance

Boasting a Mohs hardness rating of 4, Natural Grey Kota Stone possesses a highly scratch-resistant surface. It easily resists scratches from keys, utensils, and typical objects. While direct cutting with steel knives is unlikely to scratch the stone, we recommend using cutting boards to prevent dulling your kitchen knives.

Water & Porosity

This stone features a medium porosity rating. When properly sealed, it creates an impervious barrier that prevents water, coffee, wine, and oils from sinking into the stone. Spills should be wiped up promptly, especially on lighter-colored slabs, to maintain pristine cleanliness.

Available Finishes

We offer Natural Grey Kota Stone in a variety of surface finishes to suit different design needs. These include: Polished, Honed, Leathered, Bush Hammered, Sandblasted. A polished finish highlights the color depth and crystals; a honed finish yields a smooth matte surface; and a lapotra or flamed finish provides a rich rustic texture that maximizes traction.

Available Sizes

Slabs are processed and stocked in standard dimensions including: 4×4 ft (16 sqft), 5×2 ft (10 sqft), 3×2 ft (6 sqft), 2×1 ft (2 sqft), 2×2 ft (4 sqft), 2×4 ft (8 sqft).

🛒 Buying & Sourcing Guide

Installation Tips

Ensure that the supporting substrate or cabinet framework is completely level and reinforced before laying the slabs. Use premium stone adhesives or epoxy compounds rather than standard mortar to prevent moisture staining. A professional fabricator should handle joint sealing and color-matched epoxy fills.

Buying Tips

Always calculate about 10% to 15% wastage allowance for cutting and layout matching. Inspect your selected batch of slabs at our Jigani yard under natural lighting to verify pattern consistency and check for natural mineral pockets. Ensure all slabs for a single room are sourced from the same block.

Our stone operations specialists recommend Natural Grey Kota Stone for clients seeking a balance of luxury and zero-worry daily durability. It performs exceptionally well for kitchen counters and high-traffic steps. For areas exposed to dampness, ensure a water-resistant sealer is applied on all six sides of the slab.

🛡️ Care & Maintenance

Maintenance

Maintaining Natural Grey Kota Stone is straightforward. We recommend applying a high-quality penetrating impregnating sealer after installation to protect its natural crystalline pores. Depending on foot traffic and exposure, resealing should be repeated every 1 to 2 years. Sweep regularly to prevent abrasive dust particles from scratching the surface polish.

Cleaning Tips

For daily cleaning, use a clean damp microfiber cloth with warm water and a pH-neutral liquid dish soap or specialized stone soap. Do NOT use acidic cleaners, vinegar, glass cleaners, bleach, or ammonia, as these chemicals can strip the sealer and permanently dull the polished finish of the Kota Stone.
