The Nymphaea sink from Whitehaus Collection is sort of like a mood ring for your bathroom. The glass basin changes color depending on the temperature of the water.
The sink comes in a variety of crystal glass shapes including this one which is called Castle.
Light-emitting diodes provide the sink with the unique ability to change color as the temperature of the water fluctuate. The light source is powered by a safe 5-volt connection.
The sinks cost $2,500 to $3,500 depending on the style and size.
