I'm working on adding an ADU and noticed that about 80% of the 24" bathroom sinks I've checked out don't come with overflow holes. Is this a safe choice? Why are manufacturers producing sinks like this? It makes me uneasy to think of having a sink without that feature. Am I missing something here?

The main reason for the lack of overflow holes in many sinks today is cost. Making a sink with an overflow is more complex and expensive, so manufacturers often opt for simpler designs to save money. It seems like they're going for a modern, sleek look that cuts down on costs.
Exactly! Even some high-end sinks can have poorly designed overflow systems, leading many to prefer the cleaner, simpler look without extra holes.
It seems to be mostly an aesthetic choice these days. Many people want that clean, modern look, and without overflow holes, sinks can appear less bulky. But you're right, it's form over function, and sometimes those designs don't consider practical needs.
Exactly! A lot of modern designs prioritize looks over utility. It's tricky balancing style with the practical aspects.
True, it’s all about the trends now. But it’s frustrating when those trends overlook important safety features.
As a parent, I’m definitely not a fan of sinks without overflow drains. I can imagine a disaster if my kids accidentally leave the water running. Having that safety feature is really important to avoid flooding, especially if you’re in a multi-story house.
Totally get that! I have kids too and can’t imagine the mess. I feel much safer having an overflow, just in case.
Yeah, my cat used to turn on the faucet and it was a close call a few times. A sink without an overflow would have ended badly!

That’s true! Making the overflow involves more materials and quality control, which usually raises the price. Yet a lot of buyers might not even realize they’re choosing the cheaper option.
