A Concealed Shower System is a plumbing arrangement where the valve body, diverter, and supply pipes are recessed into the wall cavity, leaving only the trim plate, control handle, and water outlets visible. This design eliminates surface-mounted pipework and bulky valve housings, resulting in a smooth, architectural look that suits contemporary bathrooms, walk-in wet rooms, and luxury hotel suites. NUHU engineers concealed shower systems with a strong focus on temperature stability, serviceable internal components, and finish durability, giving installers and homeowners a reliable upgrade path from standard exposed showers. This series includes products such as Luxury Concealed Rainfall Shower System with Brass Faucet, etc.
NUHU builds concealed shower systems around a modular valve platform. The valve body is machined from DZR brass, which resists dezincification and maintains structural integrity in aggressive water conditions. Internal waterways are precision-cast to reduce turbulence and pressure loss. The cartridge is a 35mm ceramic disc design that operates smoothly and seals tightly, with an expected service life of over 500,000 cycles. The system includes a pre-assembled mounting bracket, plaster guard, and depth adjustment collar, which simplifies rough-in work for contractors.
Temperature control is handled by either a thermostatic mixing valve or a pressure-balance valve, depending on the model. Thermostatic versions maintain outlet temperature within ±2°C even when another fixture draws cold water elsewhere in the home. A scald-guard stop limits the maximum outlet temperature to 38°C by default, with a manual override for users who need hotter water. The pressure-balance models sense changes in hot or cold supply pressure and adjust internal spool position within 0.3 seconds, preventing sudden temperature spikes.
