This professional DXF template delivers complete fabrication specifications for a generously sized 48-inch by 36-inch stone shower pan featuring a 30-inch center-positioned linear drain. The 48x36 configuration provides a spacious shower floor ideal for luxury bathroom installations while maintaining excellent drainage performance through the center-mounted linear drain system. This larger format showcases premium stone materials beautifully and accommodates modern walk-in shower designs. Linear drains represent the evolution of shower drainage technology, eliminating the complex multi-directional slopes required by traditional point drains. This template provides precise geometry for a simple two-way slope that directs water efficiently to the center drain channel from both the 48-inch dimension sides. The 30-inch drain length offers substantial drainage capacity while leaving adequate space on both ends for proper slope transition. Fabricators receive complete technical specifications including slope calculations, drain pocket routing dimensions, perimeter reference lines, and CNC toolpath geometry. The template supports granite, marble, quartzite, and engineered quartz materials, with all measurements provided in industry-standard units. Compatible with all major CNC fabrication systems and CAD software platforms for seamless integration into existing workflows.
Installation Overview
Begin by verifying the rough plumbing configuration matches the template's center drain positioning. For this larger 48x36 pan, proper substrate support is critical - ensure a solid mortar bed or appropriate underlayment system rated for the stone weight. Set the linear drain body to achieve the required 1/4 inch per foot slope from both ends toward the center. Apply thin-set mortar with full coverage, eliminating any voids that could compromise structural integrity or trap water. Carefully position the stone pan, using a long level to verify consistent slope across the 48-inch dimension. The center drain channel requires precise alignment to maintain proper water flow. Install appropriate waterproofing membrane at all perimeter joints, paying special attention to the drain connection and any wall transitions. Allow full cure time before subjecting the installation to water or foot traffic. Professional installation techniques ensure optimal performance in this larger format application.
CNC Cutting Notes
Program two-way slope geometry with convergence at the center drain location, maintaining precise 1/4 inch per foot pitch from both 48-inch dimension ends. The longer span requires careful toolpath planning to maintain consistent surface finish across the entire top surface. Cut the drain channel pocket to exact depth specifications for your chosen drain model, typically 1/8 inch deeper than flange thickness for proper seating. Use sharp diamond-coated tooling for natural stone, replacing bits as needed to prevent chipping on this larger surface area. For engineered quartz, carbide tooling with reduced feed rates produces optimal results. Consider the material's length when programming - some fabricators prefer to use 3cm material for this size to provide additional structural strength. Finish all edges with appropriate profile based on installation requirements, commonly a small eased edge or safety chamfer. Always perform dry-fit verification with the actual drain body to confirm pocket depth and positioning before final polishing.
Material Compatibility
Best suited for dense granite varieties that provide structural integrity across the 48-inch span without excessive weight. Engineered quartz materials excel in this application due to consistent density and superior stain resistance. Quartzite slabs offer natural beauty with exceptional hardness for long-term durability. Marble can be used when properly sealed, though darker granites generally provide better performance in wet environments. The 48x36 size requires careful material selection to avoid stones with natural fissures or inconsistent thickness that could compromise waterproofing. Verify slip-resistance ratings for all materials, as shower floors require appropriate surface texture for safety.
