Riven Grey Sandstone Hearth – Bespoke Cut to Size & All Shapes
Riven Grey Sandstone Hearth – Bespoke Cut to Size & All Shapes - 30mm - Most Popular / Up to - 120cm × 60cm - (S) is backordered and will ship as soon as it is back in stock.
Riven Grey Sandstone Hearths
Our made-to-order riven grey sandstone hearths offer a balanced mix of durability, character and value. Each hearth is cut to your exact dimensions using precision CAD technology, ensuring an accurate fit and a straightforward installation.
Every sandstone hearth features the natural riven texture and variation that make grey sandstone such a popular option. The slightly uneven, hand-split appearance provides a rustic finish that suits both contemporary and traditional interiors.
Grey sandstone is naturally strong, heat-resistant and simple to maintain, making it an ideal material for wood-burning stoves, open fires or general fireplace hearth use. Its warm, earthy tones help create a comfortable and welcoming feel in any room.
To fully understand the material and its natural characteristics, please refer to the Specification tab, where all technical details and natural tolerances are listed clearly.

| Product Specifications | |
|---|---|
| General | |
| Product Name | Kandla Grey Sandstone – Hearth Grade |
| Material Type | Natural sandstone |
| Category | Fire hearth slab / fireplace stone |
| Country of Origin | India |
| Thickness Options | 30mm and 50mm |
| Colour Description | Mid to light grey with subtle tonal movement and natural grain. |
| Surface Finish | Natural riven / split surface with a gently textured finish. |
| Natural Variation | Medium to high variation in tone, shading and surface texture due to the natural layering and grain of the sandstone. |
| Edge Finishing Notes | All edges are precision machine-cut and then hand-sanded if needed. Due to the natural structure of sandstone, small sanding marks, slight tonal variations along the edges and occasional tiny micro-chips may be visible. |
| Weight | Approx. 70–120 kg per m² depending on thickness. |
| Density | Approx. 2,300–2,400 kg per m³. |
| Technical Characteristics | |
| Heat Absorption / Retention | High thermal mass, excellent heat absorption and steady heat dispersal. |
| Maximum Temperature Resistance | Typically performs safely up to approx. 300–400 °C before risk of thermal shock. Hearth must not be in direct contact with an open flame. |
| Compressive Strength | Approx. 80–120 MPa. |
| Flexural Strength | Approx. 7–12 MPa. |
| Porosity | Medium–high. |
| Water Absorption | Approx. 1–3%. |
| Thermal Conductivity | Approx. 2.0–3.0 W/mK. |
| Chemical Sensitivity | Generally more resistant to mild household acids than limestone, but prolonged contact with strong acids or aggressive cleaners may etch or lighten the surface. |
| Stain Resistance | Moderate; sealing is strongly recommended to reduce marking and improve resistance to staining. |
| Salt Sensitivity | Slight to moderate, as expected with natural sandstone; good ventilation and correct installation help reduce issues. |
| Natural Characteristics of Sandstone | |
| General Nature of the Stone | Kandla Grey Sandstone is a natural sedimentary stone formed from compacted sand and minerals over millions of years. Natural variations and features are part of its geological make-up and cannot be avoided or deemed as faults. These include tonal changes, layering, grain patterns and texture differences, all of which give the hearth its unique and authentic character. |
| Colour & Tonal Variation | The stone typically ranges from soft light grey through to mid grey, often with gentle banding, patches and shifts in tone. Some pieces may appear slightly warmer or cooler in shade. Selection and cutting aim to keep the overall look consistent, but variation between individual slabs and within a single hearth is normal. |
| Surface Texture & Grain | As a riven sandstone, the surface is created by naturally splitting the stone along its bedding planes. This can produce subtle riven ridges shallow indents and a gently uneven feel. |
| White / Pale Mineral Patches | Occasional lighter patches or streaks may appear where the stone contains slightly different mineral concentrations or tighter grain. These can show as soft pale bands, clouds or spots. They are natural features of Kandla Grey Sandstone and cannot be completely eliminated by selection. |
| Rust / Iron Spotting | Kandla Grey Sandstone can contain small amounts of iron-bearing minerals. When exposed to moisture and air, these may oxidise and appear as orange or brown “rust” spots, patches or halos on the surface or edges over time. This is a normal for grey sandstones and is not classed as a fault. |
| Production Enhancements | Where necessary we may use epoxy or stone filler, localised sanding, smoothing or colour-enhancing treatments to refine the appearance of the hearth surface and edges. These steps are part of our normal production process and are used to enhance the overall look of the product. They are not considered faults or signs of a lower grade material. |
| Hand-Dressed Edges | Hand-dressed edges are shaped in the quarry before the slabs are shipped to us. This process is carried out using traditional hammer-and-chisel methods to create a more rustic, natural appearance. Because this is a hand-finished technique rather than a precision machine process, natural variation should be expected. The finished edge may appear flatter in some areas and more pitched or angled in others. Some sections may be slightly rougher or more irregular, and occasional small chips or missing fragments can occur where the stone naturally fractures during dressing. These variations are completely normal for genuine hand-dressed sandstone and are not considered faults. We can only offer hand-dressed edges on three sides in a selection of fixed widths, typically 150cm, 120cm and 90cm. If you request a custom width outside these standard sizes, we will contact you to discuss options. In most cases we can offer either the front edge dressed only or give you the opportunity to amend your required size or choose an alternative edge type. |
| Application & Packaging | |
| Suitable For | Fire hearths, stove bases, fireplace hearths, chamber floors, inglenooks and internal stone features. |
| Application | Fire hearth. |
| Sealing | Sealing is recommended to reduce marking, limit water absorption and improve resistance to staining and everyday spills. |
| Installation Notes | Install on a level, load-bearing substrate and allow for expansion gaps due to changes in temperature. The hearth should not be in direct contact with open flame. Use suitable adhesives and sealers designed for natural stone. |
| Packaging | Supplied on wooden pallets or in wooden crates with appropriate protective layers. |
| Availability | Supplied in various sizes and cut-to-size hearths, subject to order requirements and stock. |
FAST UK DELIVERY — PRICED FAIRLY AND TRANSPARENTLY
We believe delivery should be clear, honest, and consistent. That’s why we don’t advertise “free delivery” while quietly building the cost into product prices or adding unexpected surcharges later in the checkout.
