This professional-grade DXF template provides complete fabrication geometry for a 36-inch by 36-inch stone shower pan with a 30-inch linear drain positioned at the center. Linear drain systems have become the gold standard in modern luxury bathrooms, offering superior drainage performance while enabling larger format tiles and seamless stone shower floors. Unlike traditional point drains that require complex four-way slopes, linear drains allow for a simpler single-plane slope that showcases the natural beauty of stone slabs. The template includes precisely calculated slope geometry, drain channel routing paths, and all necessary reference lines for accurate CNC programming or manual layout. The 30-inch drain length provides excellent drainage capacity for this 36x36 configuration, with the center positioning creating balanced water flow from both sides of the shower floor. This design works exceptionally well with granite, marble, quartzite, and engineered quartz materials. Fabricators will find complete technical specifications including drain pocket dimensions, minimum slope requirements, and recommended waterproofing integration details. The DXF file is compatible with all major CNC fabrication equipment and CAD software, allowing seamless workflow integration from design to installation.
Installation Overview
Installation begins with verifying the rough plumbing position matches the template's center drain location. The linear drain body must be set at the correct height to achieve the required slope, typically 1/4 inch per foot toward the drain channel. Apply thin-set mortar to the prepared substrate, ensuring complete coverage without voids that could trap water. Position the stone pan carefully, checking slope with a level and confirming proper alignment with shower walls. The drain channel should be shimmed if necessary to maintain consistent slope across the entire surface. Seal all perimeter joints and drain connections using appropriate waterproofing membrane compatible with your linear drain system. Allow adequate cure time before installing wall tile or testing the shower. Professional installation ensures proper drainage performance and long-term durability.
CNC Cutting Notes
Program the top surface slope as a gentle planar cut, maintaining consistent 1/4 inch per foot pitch toward the center drain location. The drain channel pocket requires precise depth control, typically 1/8 inch deeper than the drain flange thickness to ensure proper seating. Use appropriate tooling for the material: diamond-coated bits for natural stone, carbide for quartz. Recommended feed rates should be reduced by 20% when cutting the drain channel to prevent chipping. The perimeter edge should be finished with a light eased edge or micro-bevel for safety and professional appearance. If fabricating from 3cm material, consider laminating 2cm slabs for weight reduction while maintaining structural integrity. Always perform dry-fit verification with the actual drain body before final finishing to confirm proper depth and alignment.
Material Compatibility
Ideal for granite, marble, and quartzite slabs with consistent thickness and minimal natural fissures that could compromise waterproofing. Engineered quartz materials work exceptionally well due to their uniform density and non-porous nature. Denser stones like absolute black granite provide superior long-term performance in wet environments. Materials with pronounced veining patterns can create striking visual effects when the grain pattern is aligned parallel to the drain channel. Avoid highly porous stones without proper sealing, and verify all materials meet slip-resistance requirements for shower applications.
Where to Buy
