We have a walk-in shower that has no curb/barrier between the shower and rest of the bathroom. Tiled floors, and linear drain.
We clean the hair out of the drain catch every 2-3 weeks. Every so often we forget. We are then painfully reminded again when the drain overflows, water pools and then eventually meanders two feet away, only to drip out the entrance of the bathroom onto the bedroom floor.
Is there some kind of recommended device I could put about 1.5 feet away on the floor that detects and rings an alarm if there is water?
