I love the idea of a outdoor bathtub - not a jacuzzi or hot tub with all it's chemicals but an actual tub. To be used in the same way as a hot tub - for relaxing. The idea of this began some years ago after a trip to the spa -where I soaked outdoors in a beautiful copper bathtub much like the one seen below. Pure heaven. Another great thing is when your done you can irrigate nearby flora and fauna.
