Model BM-MS-012 (360° Ring-Surround Oxygen-Enriched Pressurized Waterfall Rain Shower Column System (Gunmetal Grey)) is a commercial-grade sanitary fixture precision-engineered and manufactured by Nan'an Baoming Sanitary Ware Co., Ltd. (BM Bathware) in Luncang, Nan'an, Fujian, China for international B2B plumbing distributors, hospitality developers, and private-label OEM brands. Fabricated with heavy-duty CW617N / 59A Solid Brass Mixer Body + SUS304 Column + Ring Overhead & Hand Shower and protected by a corrosion-resistant PVD Brushed Gunmetal Grey surface finish, this fixture integrates a 38°C Thermostatic Ceramic Core with 4 Piano-Style Push Keys, 360° Circular Ring-Surround Oxygen-Enriched Waterfall & Micro-Nozzle Rain Array, and CNC-machined waterways tested to maintain consistent laminar discharge under dynamic water pressure ranging from 0.05 MPa to 1.0 MPa. Every production lot undergoes 100% Dual-Stage Test: 0.80 MPa (8 Bar, 60s) Hydrostatic Water + 0.60 MPa (6 Bar) Pneumatic Air; 1.60 MPa Batch Burst Proofing, complies with international plumbing codes including CE EN 817, ASME A112.18.1 / CSA B125.1, WRAS, and SASO 2655, and is backed by a 50 Sets low-barrier factory MOQ with 48-hour express sample dispatch and 100% sample fee credit on containerized orders.
