> So most Americans have simply no idea that thermostatic valves are a thing. Having very limited travel experience outside the US, my mental model of what the temperature control on showers was supposed to be doing was thermostatic, and I just assumed that they were just bad at it. You may have just explained one of my longest running minor peeves, which is that I've always found it basically impossible to maintain a shower temperature I find comfortable without needing to make adjustments. Given that I don't own my home at this time, I probably can't do anything about it any time soon, but at least from now on when I have to deal with the fluctuations in temperature I'll know that I'm not crazy and this is actually expected behavior.
