What Should You Keep In Mind Before Buying A Hot Tub?

Your focus should be on the three R's - Relax, Romance, and Rejuvenate. Here are the essentials:

Should You Buy Online?

The answer is, NO. Even before you begin exploring online information, promise yourself not to get carried away and make a purchase straight away on an online portal. The spa is like shoes, you have to try it out before buying. So, online is for study and short-listing, not for purchase right away.

How Many People Are You Buying the Hot Tub For?

Are you considering a family hot tub, an intimate escapade for two, or a "social" hot tub that morphs into garden spa parties? Decide the spa seat capacity you want and then explore your options.

Where Are You Planning to Accommodate Your Hot Tub?

Indoor or outdoor? This may sound too basic a consideration, but a vital one. Today, there are exclusive designs for indoor, patio, garden, lounge, backyard, and covered outdoors. It is important to first decide where you want your spa before you indulge in which type you want.

What Types of Hot Tubs Should You Consider?

These are the main type of hot tubs available:


They are the most sought-after hot tubs, for good reasons. The category offers one of the widest varieties in sizes, features, seating capacity, and of course, location settings. Being portable, these hot tubs could be in your patio this weekend if you are in an intimate mood, or in the garden next weekend for a spa party. Thus, they fit into the mass perception of an all-season hot tub for all reasons. And they are very durable and energy efficient.

What else could you ask for? Go for a portable hot tub if you want a multi-purpose, cost-effective model that fits your budget, moods, and mindset. Versatile, adaptable, and reliable are its defining characteristics.

Swimming type

Apart from relaxing, rejuvenating, or romancing, do you also want to exercise and get in shape in your hot tub? Then go for this type.

Being like mini-swimming pools, these hot tubs are large, heavy, and static. They will also call for privacy and restricted access. Hence, you will need to allot dedicated space for it, like an entire secluded section of your garden, or a separate room in your home.

Constructing a strong foundation and erecting visual barriers will add to the aggregate investment in this hot tub. Its running cost will also be high since heating large quantities of water will guzzle energy.

To look at it positively, though, you will own a swimming pool that is also a spa, rather than a spa that is a swimming pool. Choose one if you agree with this logic!

Plastic Molded

These are roto-molded plastic hot tubs, characterized by their extremely tough build and long life. Like all other molded items, they are relatively light-weight - usually weighing under 300 pounds, hence easily movable to different locations. And their contoured seats offer comfort in sitting as well as stretched posture.

A combination of these features makes molded hot tubs great for hydrotherapy, massage, and rejuvenation. All this, at a relatively high return on investment since molded hot tubs are also energy efficient.

On the flip side, these hot tubs are unattractive compared to the wood and other sleek designs. You will choose one if you prefer form, function, and cost-effectiveness over style statement.

These are recessed, custom-built hot tubs that are "dug into" your backyard or garden. They are elite and exclusive, synonymous with large secluded villas and estates.

A typical underground hot tub can be visualized as a mini aqua-blue water pool finished with Italian marble or imperial green granite, with potted plants along its peripheral border, and spacious landscaped garden surrounding it. And of course, it is tucked away in a secluded corner of a quaint villa.

Being elite and made-to-order, this hot tub has the choicest spa facilitators. If you are thinking of building one in your backyard, you will proudly flaunt its high construction and running costs. Cost-efficiency is not its intended purpose, right?


These are lay-flat polyester or laminated PVC hot tubs that can be inflated when needed. They are available in a wide range of fancy shapes and designs.

Inflatable hot tubs are in the convenience category. They don't cost the world but also don't offer many of the exclusive features of hot tubs. They don't have seats and they are relatively shallow, so you will just float in them.

A big disadvantage of inflatable hot tubs is that they can be easily punctured. A single thorn prick or an abrasive rock cut, and all your investment will go in vain. Or, the plastic could get damaged by hot water or direct UV rays. To balance it, you can always deflate it and carry it with you to the beach or in the jungle.

Choose an inflatable hot tub if you don't want to invest heavily in a permanent spa but prefer low-cost, temporary, and "disposable" variant. Or, if you are a traveler who wants the luxury of hot tubs wherever they go.
