The Hansgrohe Ecostat Comfort S is a built-in shower thermostat in a matte black chrome finish, designed for precise temperature and flow regulation. This single-function thermostat features a 155 mm escutcheon and requires a wall-mounted installation. The thermostat ensures reliable temperature stability with an integrated 40 °C safety stop to prevent scalding, which is particularly beneficial for households with children or individuals with limited mobility. The flow regulation allows for exact adjustment of the water volume via the thermostat control, contributing to water savings and reducing daily consumption. The thermostat cartridge delivers a flow rate of 21.3 l/min at 3 bar pressure. Installation is simplified by the pre-assembled functional block and compatibility with the iBox universal 2 flush-mounted station. The escutcheon can be adjusted within ±3° for precise positioning. This model is the successor to earlier Ecostat Comfort versions and requires a separate flush-mounted station for complete installation. The matte black chrome surface provides a durable, corrosion-resistant coating that maintains its appearance with minimal maintenance over time. Designed for operation with a single fitting, this thermostat mixer combines German engineering precision with practical safety features for consistent shower comfort.
