Yes, granite hearths can be used for wood-burning and solid fuel stoves, but they must be in a continuous solid slab rather than installed as multiple pieces to conform to Australian Standards.

• Solid Fuel / Wood Stoves: Require a “slabbed” granite hearth. The granite is cut into slabs into shape. If a hearth is made up of multiple pieces, it must have a single continuous solid piece of non-combustible cement sheet below it.
• Gas & Electric Fires: Can safely use a single solid piece of granite, but may not be required.

The primary difference lies in the surface finish, reflectivity, and visual aesthetic:

• Polished Granite: Features a smooth, high-gloss, reflective surface that enhances the stone’s color depth and natural grain patterns. It is non-porous, easy to wipe clean, and brings a traditional, luxurious look to the fireplace.
• Honed Granite: Has a smooth, flat, matte finish without shine. It offers a contemporary, subtle appearance and is less likely to highlight surface scratches.
• Leathered Granite: Has a smooth but textured finish. The finishing process removes some of the softer material and leaves a subtle bump throughout the stone and is a mix between honed and polished.

Standard solid granite hearth slabs are typically 20 mm thick, which provides the structural strength required for most freestanding stoves and inserts.

• Standard Slabs: A single 20 mm slab sits close to the floor for a sleek, modern profile.
• Boxed & Lipped Hearths: If a higher profile is desired or required by building codes, granite risers can be glued underneath the top slab to create a “boxed and lipped” effect, raising the total height to 50 mm or more.

Clean a granite hearth using warm water and a few drops of pH-neutral dish soap, wiping the surface down with a non-abrasive microfiber cloth, and drying it immediately with a clean towel.

• Avoid Harsh Chemicals: Never use acidic cleaners (such as vinegar, lemon juice, or window cleaner), bleach, or abrasive scouring pads, as these can dull polished surfaces and erode sealant.
• Soot and Ash Removal: Vacuum loose ash using a soft brush attachment before wiping down to prevent fine dust from scratching the polish.

Granite is widely considered the most durable and versatile material for a fireplace hearth due to its exceptional hardness, heat resistance, and low porosity.

• Granite vs. Slate: Granite is significantly harder and far less prone to scratching or chipping than slate.
• Granite vs. Limestone: Limestone is softer and highly porous, making it susceptible to cracking under high heat and staining from ash.
• Granite vs. Marble: Marble is sensitive to acidic cleaners and prone to discolouration from direct heat, whereas granite holds its color and finish over decades of heat exposure.

Yes, granite hearths require a level, rigid, sub-base due to their weight. A non-level base can be a cause for uneven loading and possible cracks.

• Leveling & Support: Because granite is heavy and inflexible, an uneven sub-floor can create stress points that cause the stone to crack under the weight of a heavy stove. Installations typically use a sand-and-cement mortar bed to achieve uniform support.
• Building Regulations: Hearth dimensions must extend beyond the firebox opening according to regional building codes (typically at least 300 mm in front of a wood burner).
• Professional Fitting: Having the hearth installed by a certified fireplace professional ensures full compliance with local fire safety standards and building regulations.
