It happens with freeze-proof valves. They work because the valve body is way back in the wall, on the warm side of the insulation. The idea is that the portion downstream of the valve body, which is on the cold side of the insulation, is dry when the valve is off. But if you leave a hose connected, it can trap water there. That portion of the valve then freezes, and because it's downstream of the valve body, you don't know it until next spring when you turn the valve on. I've had that very thing happen -- fortunately, in my case, the only area that was flooded was a basement room which was unfinished at the time.

I went crazy building my new house and ran alarm wire to pretty much every plumbing fixture in the house. I have wired up 15 of those locations with acutal sensors. I have been thinking of hiding the ones in the bathroom with pedastal sinks by making a little box out of the floor tile that just sits over the top of the sensor. Water of course will still get under the box and trip the sensor. In the bathrooms with regular cabinet style vanities I hide the sensor under the vanity. If the toilet leaks, it will still get under there soon enough.

Lou, I have a pedestal sink in a half bath. The back of it is open - the pedestal isn't solid. I wonder if you could hide the sensor inside the base. The cable extending to it would be fairly inconspicuous, particularly if you painted the cable similar to the floor color.
Edit - you have to admit, thought, that the GRI sensors are very small in size, and not really noticable.
