<h1 class="subject">Is there a lock for tubs and sink faucets?</h1>

My friend's 7 year old daughter is Autistic and has a fasination with water therefore she's having trouble potty training. She's already flooded the bathroom 3 times so she has to keep the door locked. Is there a device that locks the faucets of the tub and sinks?

I've been a locksmith for a long time and I've never seen anything like that. They make them for everything else right down to tv cord ends so the kids can't plug them in. Good idea for a patent though
