    Wax elements are also used in thermostatic valves for faucets (to keep faucet temperature constant given variable hot and cold mains): <a href="https:&#x2F;&#x2F;rogerdickey.com&#x2F;the-ideal-faucet&#x2F;" rel="nofollow">https:&#x2F;&#x2F;rogerdickey.com&#x2F;the-ideal-faucet&#x2F;

      Hard disagree with that faucet design, but is a neat idea. I like my bathroom faucet as low maintenance as it already is.

      The use case for the full unmixed hot tap is hygiene (usually washing face and shaving).

      I also don&#x27;t want any hot water mixed in when I&#x27;m washing my hands. The water coming out of the unmixed cold tap indicates the ambient temperature of the pipes. That&#x27;s a feature, not a bug.

        at least in my home, both the cold and the hot water are very uncomfortable to wash my hands in, but mixing it right takes ~15s every time so i usually just accept the discomfort

            I think it takes time because the hot water line doesn’t immediately return hot water

              About 3-5 seconds depending on plumbing.

                ... if you have a recirculator. The farthest faucet from a water heater takes around 60-90 seconds to deliver actually hot water at my house.
