The wooden hot tubs are by far the most popular variety of hot tubs. The hot tub is actually constructed like a large barrel. It has wooden staves and steel bands. Redwood, cedar and teak are commonly used to make the staves. Most of the older hot tubs are made of redwood. The wooden tub is quite deep inside, approximately between 36 to about 48 inches in depth. There is an inset within a wooden deck, so that it is easy to enter the hot tub. There is a seating arrangement inside the tub, and this is generally in the form of wooden benches. The bench forms a ring around the inner circumference of the tub.
Nowadays, the one-piece hot tubs are also quite common and have many advantages as well. They are also known as unibody spas. The tub is actually a formation of one piece with shapes and various seating arrangements are provided inside the tub. There are one or more water jets attached to each integral seat. In this way the water is directed to all the parts of the body and provides the massage. Sometimes all the water jets may automatically move or rotate, again providing the effect of a massage.
