KATAIS builds its thermostatic shower system around a single, clear piece of information: the exact water temperature. The digital display, powered by water flow, eliminates the guesswork before you step in. This focus on control and clarity defines the entire setup, which includes a comprehensive array of spray options from a ceiling-mounted rain head to six body jets.

The solid brass construction in a matte black finish provides a substantial feel. The thermostatic valve is the core, maintaining your selected temperature even if someone flushes a toilet elsewhere in the house. You operate everything through five dedicated handles—one for the overhead shower, one for the handheld, and individual controls for each pair of body jets. This allows precise customization, letting you run just the rainfall head or activate a full-body immersion.

Installation is a significant undertaking, requiring precise plumbing for the ceiling shower arm and the six wall-embedded jets. This system is designed for a full bathroom renovation, not a simple swap. The payoff is a spa-like experience with authoritative, drenching coverage from every outlet, all held at a perfectly steady temperature you can see at a glance.
