Wood Hot Tubs vs. Acrylic Spas

ROUND ONE - APPEARANCE

Both spas and hot tubs have appealing designs, but the natural wood staves of a hot tub, and the round shape has a more zen-like feel. Wrapped in a beautiful wooden deck and steps (which also hides the equipment and helps to retain heat, is the most beautiful approach to hot water soaking. The smell of the redwood or cedar wood gives off a natural aromatherapy

Winner: Hot Tubs

ROUND TWO - COMFORT

Early wooden hot tubs didn't even have benches, you had to stand up! Most hot tubs have simple wooden benches around the edge of the tub at different levels or depths. Hot tub walls are straight, and frankly, not that comfortable. Spas, on the other hand, have buckets seats, molded lounges and head rests.

Winner: Spas

ROUND THREE - COST

With a wooden spa, you can definitely spend more than for an acrylic spa. Or, you could also build your own, from a kit or from scratch (or from an old wine vat like my father) and save quite a bit of money. But comparing an assembled wooden hot tub with heater and filter to a modern spa of similar size, hot tubs are more expensive. A DIY wood hot tub, coupled with one of our spa packs, is cheaper than most new spas.

Winner: Hot Tubs

ROUND FOUR - FEATURES

round-4

Spas pummel hot tubs in this round! Modern spas have cool lighting, controls, waterfalls, audio/video. Hot tubs with a spa pack also have digital controls, and lights can be added to a hot tub, but most hot tubs are decidedly low-tech, and not usually feature rich. With a transistor radio and a nearby stream, you have all you need.

Winner: Spas

ROUND FIVE - MAINTENANCE

Hot Tubs made of wood understandably require more maintenance than hard acrylic or rotomold spas. The wood exterior should be stained and sealed every few years (just like a spa cabinet), and the inside should never be treated, only cleaned with a stiff brush and a hose when draining. Filter and chemical maintenance should be the same on both types, although the more equipment you have - the more potential for maintenance exists.

Winner: Spas

ROUND SIX - SANITATION

Spas and hot tubs are equally sanitary when filtered and treated with spa chemicals, without which, both types would become green and potentially unsafe. However, spas, with their miles of hose and pipe, creates an ideal environment for biofilm, which can grow in poorly treated spas, or spas left empty. Hot tubs typically have very little plumbing for biofilms to form colonies. Although the smooth surfaces used in spas help with a clean surface, wood contains natural antiseptics, especially the rot and insect resistant types of wood used in hot tubs. This helps inhibit algae and bacteria from growing on the surfaces, kind of like Microban.

Winner: Hot Tubs

ROUND SEVEN - EFFICIENCY

Hot tubs made of wood are not as efficient as a well insulated acrylic spa with cabinet, even though both can use insulated hot tub covers. The thickness of the wood matters, and a hot tub can hold heat for hours, but it can never be as efficient as a well insulated spa. A poorly-insulated spa perhaps, but not one that is well insulated. However (always a caveat), if your hot tub is heated with wood, your electrical use will be less than a spa.

Winner: Spas

ROUND EIGHT - DURABILITY

Even a well maintained wood hot tub will eventually develop wood rot. This can be repaired and stopped, or one can use a vinyl liner made to fit your spa, like a small aboveground pool. Even so, it is unlikely that a wooden hot tub can be continuously used for longer than 30 years. The surfaces of plastic or acrylic spas can scratch, chip or fade, but are generally impervious to structural damage. You could continue to rebuild a spa forever, I suppose - or at least 50 years.

Winner: Spas

Let's see, that's 5 rounds for spas, and 3 rounds for hot tubs. Some rounds were close, and both fighters gave it their all - but spas win!

On the surface, it looks like Acrylic Spas have more benefits than their wooden ancestors. But for people like my father, proud to have once told me that he has "never been in one of those flooded boats" - there is nothing like a wooden hot tub with a wood fired heater, especially for homes that have lots of 'natural' appeal.
