NO. Never have heard of one.
Has anyone run into a bathroom sink stopper with overflow protection built in? i.e.; electronic or pressure release to stop accidental overflow.
My OVE sink has no overflow, I really don't want a cleanup drain in my bathroom floor...
for far too long people have objected to having overflow holes in their sinks. Used to be a Code requirement, now no longer is. Anyone who wants a sink with overflow can still buy one. Thousands of models out there.
I sell quite a few custom vanity tops. You can pay anywhere from $10 to $20 per overflow on a custom top.
I ask my customers whether the bath is adult only or not. If it is an adult bath I recommend that they save their money, and spend somewhere else in their bath.
An adult usually won't turn on a faucet, pull the plunger and walk out of the room. If it is a drain problem an overflow won't help anyway.
