I’ve noticed that too, and it drives me nuts when you move the handle the “wrong” way and get blasted with hot water. From what I’ve seen, a lot of it comes down to whoever installed the faucet not paying attention to the supply lines. If you want to fix it, you can usually swap the hot and cold lines underneath—just shut off the water, unscrew the hoses, and switch them. Sometimes with single-handle mixers, though, the cartridge is designed for a specific orientation, so if it’s backwards, you might need to rotate or replace the cartridge itself. Not hard, just a bit fiddly. I wish there was more consistency with these things...

Yeah, you and me both. I’ve lost count of how many times I’ve gone to someone’s house, turned the handle the way I *think* is cold, and nearly scalded myself. It’s like playing faucet roulette. Honestly, I’m not totally convinced it’s always the installer’s fault, though. Sometimes the manufacturer instructions are so vague or the labeling is just plain confusing—especially with those “universal” cartridges that apparently fit everything but actually fit nothing.
Had a bathroom reno last year where the hot/cold were reversed and I thought, easy fix, just swap the hoses. Nope. Turns out the cartridge itself was designed for a European setup or something. Ended up having to order a new one because rotating it made the handle point straight at the wall. Go figure.
Anyway, I agree it shouldn’t be this complicated. You’d think after all these years we’d have a standard, but nope... every faucet’s got its own little personality.

That’s exactly it. I’ve got a couple dozen units and every time I do a turnover, I brace myself for the “which way is hot?” question from new tenants. The worst is when you get those single-handle mixers where left is hot in one bathroom, but right is hot in the kitchen. Drives people nuts.
Honestly, I blame both the manufacturers and the lack of enforced standards. In theory, North America’s supposed to be hot on the left, cold on the right, but once you start dealing with imports or “universal” parts, all bets are off. I’ve had to swap cartridges or even flip supply lines under sinks just to get things consistent—sometimes it works, sometimes you end up with a handle that hits the backsplash or points at your knees.
If you’re doing renos or installations, double-check before closing everything up. Saves a ton of headaches later.
Yeah, I totally get the frustration.
It’s wild how often that happens. I’ve run into setups where even the same model faucet gets swapped around depending on whoever did the install. Honestly, it’s not always just imports—sometimes it’s just someone rushing or not paying attention. You’re spot on about double-checking before closing up. Saves a world of pain later when you don’t have to explain to someone why “hot” is a guessing game.The worst is when you get those single-handle mixers where left is hot in one bathroom, but right is hot in the kitchen.
I get where you’re coming from, but sometimes I wonder if it’s not just carelessness. Some older houses have weird plumbing runs that force the installer to swap lines, or the pipes are mislabeled behind the wall. It’s not always as straightforward as just paying attention, you know? I’ve seen diagrams that make zero sense once you open up the wall...
