In Hot Water—and Air

Coincidentally, I am blue with the cold [thank you for asking], but there's an unseen reason behind today's post. The cavity between the inner and outer walls of the Etna bathtub contains a network of pipes that circulate heated water around the body of the vessel. This not only keeps the bath water hot without repeated topping off, but also warms the ambient space of the room. The LED lights are optional, and there's a coordinating pedestal sink.
