The only correct kind of faucet is the kind with a thermostatic handle for temperature, and a separate handle for flow.

They are almost exclusively available for showers and that’s stupid. It’s the correct solution for the problem, with extremely few drawbacks.

The only improvement I could see is making the temperature handle short circuit to the drain until the water going through is hot enough. But I dont know if that’s really possible without electronics, and I really dont want my faucet handles to be plugged in or take AA batteries.
