The single outlet matt black Harbour Status concealed shower valve is thermostatically controlled meaning that the water temperature will not vary from that which you've set, even if the pressure fluctuates or someone else in the house uses another tap. There's no more constantly fiddling with the controls trying to find and then keep the right temperature. You can just stand, relax and enjoy looking at the exquisite Matt Black finish. The thermostatic control also prevents scalding and will automatically shutdown the valve should the hot or cold water supply fail. Not only that, but thermostatic controls have a built in safety limit, so should your child find themselves with free reign of the shower, they won't be able to turn the hot water high enough to injure them. The Status shower valve comes with 5 years guarantee.Features:Single outlet shower valve in an eye-catching Matt Black finishThermostatic valve with auto-shut off mechanism protects you from sudden changes in temperature
