What every best Hot Tubs has:
- Adjustable jets.
- Low heat loss.
- An energy-efficient heater.
Mid-range prices. The wooden hot tubs available online cost about the same as a mid-range above-ground model molded type, and retail site RHTubs.com says they should cost about the same to operate. A wooden hot tub is generally deeper than a molded above-ground spa, so, although it contains more water, it has a smaller exposed surface where heat can be lost. However, this greater depth means the tub is very heavy when full, so keep that in mind when picking out your installation location.
Wood holds up well. RHTubs.com reports that "unlike plastic spas, wooden hot tubs don't crack, chip, blister, bubble, fade or stain." Still, this site and other sources note that the type of wood used is important. Redwood, cypress and teak are all very durable. Some say that cedar -- a popular wooden hot tub material -- may not hold up quite as well, but DoItYourself.com notes that cedar is a good choice for a hot tub because it expands when wet, making it more water-tight. Oak is another possible choice, but experts note that oak needs careful maintenance. Thicker wood is also better since it's less likely to warp. Most wooden hot tubs don't need any special maintenance, but if you choose to finish the wood, you'll probably need to renew that finish annually.
Fewer features, but more flexibility. In general, wooden hot tubs don't offer the same range of features as molded above-ground spas. They have simple wooden benches rather than contoured seats and loungers, and don't include extras like sound systems. However, wooden models are easier to customize than molded tubs because you can choose the bench height and exact placement of the jets. Another plus is that wooden tubs are shipped in pieces and assembled on site, making it easier to fit the tub into a location with limited access. Many have heaters separate from the actual tub, so you can choose gas or even wood rather than electricity for heating.
Rustic looks. For many users, the biggest advantage of a wooden hot tub is the beauty of natural wood. Left unfinished, a wooden spa will age to a grayish tone over time, which many owners find appealing. Those who prefer the look of fresh-cut wood can finish the outside surface. Buying a wooden hot tub isn't the only way to get the appearance of wood, however; many molded tubs come with wooden cabinets or synthetics designed to look like wood. But for those who want a spa made entirely of natural materials, a wooden hot tub is the way to go.
