The Nuie Aztec Triple Concealed Thermostatic Shower Valve with Diverter pairs a minimalist square wall plate with three crosshead handles in a bold matt black finish. A central thermostatic control sets your temperature while the integrated diverter directs flow across three outlets – ideal for a full shower system with a fixed overhead drencher, handset and body jets. The concealed installation keeps pipework hidden behind the wall for a clean, uncluttered look, and the valve can be fitted vertically or horizontally to suit your installation.

Thermostatic technology holds your chosen temperature to within ±2–3°C even when water pressure fluctuates elsewhere in the home, and the valve shuts down automatically if the hot or cold supply fails, providing full thermal protection. The British-made quarter-turn ceramic disc cartridge is highly resistant to limescale build-up and is fully reversible, so if the hot and cold supplies are plumbed the opposite way round there’s no need to re-pipe. Suitable for all plumbing systems, including gravity fed, pumped, unvented high pressure and combi boilers, with a minimum operating pressure of just 0.1 bar.
