This shower fixture features a built-in thermostatic valve core that automatically maintains water temperature at a steady 38° Celsius, eliminating unexpected sudden shifts in hot or cold water flow that can cause discomfort or accidental scalds. The dedicated 38°temperature lock adds an extra layer of safety for young children and elderly household members who may be more sensitive to extreme water temperatures. Its solid brass integrated cast main body comes with a durable black finish that resists corrosion, withstands regular water pressure, and prevents accidental bursts for long term daily use. It fits standard 4 in. center mounting spacing, requires no specialized professional tools or plumbing expertise for quick setup, and its compact footprint works well in standard residential bathrooms, recreational vehicles, and yachts. The dual knob layout lets users adjust water flow and temperature separately to cut down on unnecessary water waste, while its streamlined unobtrusive look blends seamlessly with most existing bathroom decor styles.
