Sink with No Overflow?


We just installed a stainless steel sink in our small bathroom and noticed that it does not have an overflow built into it.

Does plumbing code require bathroom sinks to have over flows? Kitchen sinks don't have overflows....so why do bathrooms have them?

Every state has different codes, not sure about California, I'm sure someone here does. Check your local municipality for the proper code.

IMO, I would guess that kitchen sinks don't have them because how often do you plug them up and run water. Just about all kitchens today have dishwashers so there is really no danger of overflowing.

Bathrooms are just the opposite because they are often plugged and filled with running water.

IMO, as long as the sink doesn't get plugged and you are the homeowner, I don't see any problem. If you ever sell the home, a sharp building inspector might catch it and make you change it, if it's a code violation in California.

Overflows not required by UPC- but, when equiped on sinks or lavs, they must connect to the house side of the trap
I had to look that up- good question ddawg

What a neat space saving sink. I like it ddawg. Allows for maximum use of space. Nice job with the dry wall, perfectly square.

Some pop up stoppers will not drain properly with out the overflow ---so get a good one that opens wide---

Looks like a reclaimed old Ship lav. You could probably find a local shop that does Stainless work, and have them weld in a overflow on there. That would mean that you would have to find a tail that would work for the extra length, to allow for the C that would form the drain for the overflow, to the opening for the main drain.
