One-piece cast brass pre-buried valve body, zero leakage risk
The hidden pre-buried valve body, water pipes and water cavity are integrally cast from whole H59 brass without sand holes or welded seams. It provides excellent sealing after embedding into the wall, fundamentally preventing internal water seepage and wall mildew. Natural copper ions inhibit limescale and bacteria for healthier water use.
48-hour salt spray multi-layer chrome anti-corrosion coating
Exposed panels, spouts and levers are covered with thick multi-layer mirror chrome plating. The whole unit passes 48-hour neutral salt spray test, resisting oxidation, blistering and rust in long-term humid bathrooms, maintaining long-lasting mirror gloss, far superior to stainless steel and zinc alloy wall taps.
Thickened brass structure anti-deformation
The thickened square water outlet arm has stable load-bearing capacity and will not sag after long-term use. The oversized square cover plate fully covers wall mounting holes for beautiful installation with fewer gaps to trap dirt.
Uniform sharp square geometric silhouette
Panel, spout and control lever all adopt neat square shape with crisp edges, simple and premium, matching black-white-grey, cream and all modern home styles with clean visual effect.
Hidden split pre-buried structure to save counter space
The valve body is embedded inside the wall, only the panel, spout and lever exposed, occupying zero countertop space. Perfect for floating bathroom cabinets, ultra-thin rock slab countertops and wall-mounted wash zones, keeping vanity tops tidy for easy cleaning.
Extended forward square spout
The horizontally stretched straight square spout guides water to the center of basin, greatly reducing splashes on walls and countertops when washing hands, faces and hair with wider operating range.
Side square single lever integrated control
Vertical square lever on the side adjusts water volume by vertical lift, switches hot/cold temperature by horizontal swing, delivering smooth labor-saving one-hand operation. Separated lever and spout design makes flow & temperature adjustment clear and easy to distinguish.

FAQ
Are both pre-buried valve body and exposed parts made of solid brass? Will it leak or rust after embedding into the wall?
A: The pre-buried valve body, internal water channels and spout base are integrally cast from standard H59 brass without welded seams. All exposed parts are covered with multi-layer chrome plating passing 48-hour neutral salt spray test for moisture and rust resistance. The pre-buried brass valve body provides strong sealing to prevent wall seepage with natural antibacterial properties of brass.
How to adjust water flow and temperature with the side square single lever? Is the operation smooth?
A: Lift or press the side square lever vertically to control water volume, swing left and right to switch hot and cold water, all adjustments can be finished with one hand. The built-in wear-resistant ceramic cartridge ensures smooth operation without jamming or dripping after tens of thousands of uses and stable temperature output.
Is wall-mounted tap complicated to install? Can it be retrofitted on finished bathrooms?
A: This split pre-buried design requires embedding the brass valve body and installation box before wall tile laying. It is not suitable for finished walls without pre-embedded space, only applicable for new house decoration and bathroom renovation stages.
What performance tests does each product pass before delivery? Is the quality stable and reliable?
A: Only products passing all full-item tests of pre-buried valve and exposed components can leave warehouse with 100% qualification rate. Test items include water pressure resistance test, water flow test, water channel burst test, 48-hour salt spray test and ceramic cartridge tens of thousands of cycles durability test, fully stabilizing pressure resistance, sealing and anti-corrosion performance.
Does your factory accept customization? What can be customized?
A: Full-range personalized customization service is available. We can customize electroplated surface colors, spout length and panel size; laser engrave customer brand logos; customize packaging styles and outer carton printing. We can also deliver complete accessory sets including pre-buried boxes for hotel engineering and bulk distributor orders.
Is the square electroplated panel easy to scratch, fade or peel after long-term use?
A: Adopting thick multi-layer mirror chrome plating with strong adhesion and qualified hardness via salt spray test. Clean daily only with soft cotton cloth, avoid scrubbing with steel wool or strong acid/alkaline cleaners, the surface will not peel, mottle or fade after years of regular household use.
