Description
The 48x18 corner hearth template is specifically designed for fabricators working with L-shaped fireplace installations where the hearth wraps around an adjacent wall or alcove. This compact corner configuration is ideal for smaller fireplace installations, corner-mounted stoves, or space-efficient designs in modern homes. The template provides precise cutting paths for creating a professional corner hearth that maximizes usable space while maintaining structural integrity and aesthetic appeal. This DXF template works seamlessly with all CNC fabrication equipment and is compatible with granite, marble, quartz, quartzite, and engineered stone materials. The 48-inch width and 18-inch depth dimensions follow standard architectural proportions for residential fireplace hearths, ensuring proper clearance from combustible materials while providing adequate protection for flooring. The corner design features mitered edges that create clean, professional joints where the two perpendicular sections meet.

Installation Overview
Installing a corner hearth requires careful measurement of both wall surfaces to ensure the L-shaped slab fits precisely within the allocated space. Begin by verifying that the fireplace opening is square and that both walls form a true 90-degree angle. The hearth should extend at minimum 16 inches from the fireplace opening per most building codes, though this 18-inch depth provides additional safety margin. The corner hearth typically rests on a reinforced substrate or corbelled masonry support that can handle the concentrated weight at the corner junction. Apply a continuous bead of high-temperature construction adhesive along the support surface, then carefully position the stone slab ensuring both legs of the L-shape are equidistant from their respective walls. Check for level in both directions and shim as necessary before the adhesive sets. Seal all edges with a flexible, heat-resistant caulk to prevent debris accumulation.
CNC Cutting Notes
When programming your CNC to cut this corner hearth template, pay special attention to the mitered corner where the two perpendicular sections meet. This internal corner requires a precise 90-degree cut to ensure the finished hearth sits flush against both walls without gaps. Use a fine-grit diamond blade for the finish pass to minimize chip-out along these critical edges. The exterior corners of this design should be finished with a slight chamfer or radius to prevent chipping during handling and installation. Program your toolpaths to complete all internal cuts before perimeter cuts to maintain slab stability during fabrication. For materials prone to thermal stress fracturing like granite, reduce feed rates by 15-20% when approaching corners to minimize vibration-induced microfractures that could compromise long-term durability.
Material Compatibility
This corner hearth template performs exceptionally well with heat-resistant natural stones including granite, soapstone, and slate, which are traditional choices for fireplace applications due to their thermal stability. Engineered quartz can also be used for gas fireplaces or decorative installations with minimal heat exposure, though manufacturers typically recommend keeping quartz away from direct flame contact. Marble and limestone are suitable for electric or gas fireplace surrounds but should be sealed with a penetrating sealer to resist soot staining and discoloration from heat exposure over time.
