Shower Drain Manufacturer & Factory

Our no-caulk mechanisms (models JN-6301, JN-6302, and JN-6303) utilize a precision-profiled conical elastomer compression gasket molded according to ASTM D2000 specifications. When the heavy-duty brass compression nut is torqued into the drain throat using our supplied spanner tool, radial compression forces the neoprene sealing ring inward against the exterior circumference of the 2-inch DWV pipe while simultaneously expanding outward against the internal bore of the drain body. This mechanical joint withstands over 25 PSI of sustained hydrostatic test pressure without weeping, completely removing installer reliance on silicone caulking, plumber's putty, or solvent glue.

JANA maintains active listings with IAPMO R&T for both UPC and cUPC certification conforming to the harmonized standard ASME A112.18.2 / CSA B125.2 (Plumbing Waste Fittings). Certificate files (including File Nos. 6229, 8175, 12307, N-11587, and T-11586) confirm passing criteria for thread dimensions, flow capacity, vertical point-loading resistance, and thermal shock cycles from 40°F to 150°F. For municipal jurisdictions enforcing stringent toxicity thresholds, our solid brass SKUs are third-party certified lead-free under California AB1953 and NSF/ANSI 372.

Our Thailand factory (Gateway Enterprise Corporation, Kabinburi) is a fully recognized manufacturing entity covering 14,400 square meters. Drains produced here undergo raw material shaping, stamping, CNC threading, and final packaging within Thailand. Consequently, goods shipped from Thailand are issued official Thai Certificates of Origin, enabling North American buyers to import products completely insulated from Section 301 tariffs applied to Chinese-origin goods. Clients can designate shipment origin based on their unique supply-chain risk profile and pricing strategy.

For standard catalog items (such as the JN-6304 ABS series or JN-6329 snap-in strainer grids), our standard production MOQ is typically 1,000 units per SKU. For custom OEM branded designs (custom architectural hole perforations, proprietary snap-in clips, or private-labeled locknut castings), progressive stamping tooling is designed and manufactured in-house within 20 to 25 calendar days. First article inspection (FAI) sample approval requires 7 days, with bulk production ramping to 30,000 units per month within 35 days following approval.

We manufacture plastic shower drain bodies (JN-6304 through JN-6307) in two distinct virgin material formulations: virgin Acrylonitrile Butadiene Styrene (ABS) and Polyvinyl Chloride (PVC). Each matches regional construction norms (ABS preferred in western US and Canadian installations; PVC prevalent in eastern US and southern markets). Both types feature precision solvent-weld hubs meeting ASTM D2661 (ABS) and ASTM D2665 (PVC) standards, assuring molecular fusion with corresponding DWV piping using standard solvent cements.

Our architectural decorative finishes are engineered to survive repeated exposure to commercial surfactants, bleach, and sulfamic acid scale removers. Polished Chrome finishes feature a multi-layer barrier of semi-bright nickel, bright nickel, and microporous hexavalent chromium. Specialty finishes such as Matte Black and Brushed Brass utilize vacuum-chamber Physical Vapor Deposition (PVD). PVD creates a molecular bond with the brass substrate that resists abrasion, scratches, and salt corrosion far better than standard organic powder coats or aerosol lacquer dips.
