Investing in one of the best inflatable hot tubs is enticing for many reasons, including the low initial cost and hassle-free installation. Outdoor inflatable hot tubs are also suitable for maintenance, cleaning, and storage. If you're using your inflatable tub as a test run for buying a proper hot tub, then cleaning and maintaining the pH levels of the water, as well as keeping unwanted debris out, will be an excellent learning experience before you commit to a permanent installation.
One drawback is that inflatable hot tubs with seats are rare. Although manufacturers may advertise a model with a certain number of seats, this most likely means the number of persons that can sit on the bottom of the tub, not that there are any actual seats. However, if you want seats to add to your inflatable hot tub, they can sometimes be bought online. Manufacturers often sell specific seats that are compatible with certain models of inflatable tubs.
Inflatable hot tubs are almost always made from either PVC or vinyl and come with an external combination pump and heater unit that controls both the water temperature and the massage jets. Inflatable hot tubs can generally be set up in 15 or 20 minutes and filled with a garden hose, and most can heat water to comfortably hot temperatures overnight.
Construction: Layered vinyl or PVC is standard for inflatable hot tubs, but many models have walls reinforced with fabrics like polyester or nylon. This is usually indicated with a proprietary name: Intex calls its unique blend of materials Fiber-Tech. Coleman uses Tri-Tech 3 Layer Material for its polyester mesh and layered PVC mix.
The design and structure are just as important as the material. Many manufacturers use a segmented inflatable design reinforced with a vertical I-beam internal structure. These internal vinyl panels make for a sturdier tub that can support users when they lean against it or even sit directly on the outer wall. Premium models add another level of stability and protection with interlocking panels surrounding the inflatable tub. These also provide a rigid wall that protects and insulates the tub.
Covers: All inflatable spas should include a locking top cover for safety. In some cases, this cover also insulates the tub and accelerates the water-heating process. Some models include inflatable covers that fit into the top of the tub like a stopper in a bottle, while others use insulating materials like foam or foil lining to keep the heat inside. Regardless of insulation style, you'll want a cover that offers more than a fitted piece of fabric.
Other accessories: All sorts of accessories are available for maintaining and enjoying your portable spa, from chemical dispensers to inflatable cushions. If you plan to leave the tub filled for days or weeks at a time, you should choose one that includes chemicals like chlorine or bromine, along with the necessary dispenser and test strips to monitor the water's pH levels.
