Where is this?

United States, more specifically at my work in the workout area's showers.

That's a good sign. That means that the shower valve is probably thermostatic and will adjust itself to changes in water pressure and water temperature.

I want one.

Does it shoot out water with 300 pounds of torque when the handle falls off? Jk

Interesting, usually my shower can only be set to boiling hot or freezing death. No between

I wish they’d put the Celsius in even 5 degree spacing instead. It works this way but it kinda defeats the purpose.

Is that in MPH?

Sorry, but isn’t this the default for showers build in the past 30 years or so?

I've never seen this before.
