The Blue Wave Radiant Saunas Simplicity 4-Person Inflatable Spa is aptly named, with a basic inflatable tub design and combination pump and heater. As inflatable hot tubs go, it’s fairly light and portable, and it comes with some helpful accessories.
Made of puncture-resistant, three-ply, cross-laminated PVC, the tub is also protected by an exterior cover of tough artificial leather. The round inflatable tub sits 27 inches high, measures 65 inches across and has an interior diameter of 51 inches. Designed for quick setup and easy transport, the uninflated, unfilled tub weighs just 51 pounds, making it one of the lightest inflatable hot tubs we've seen. The included heater and pump unit runs on any standard 110- or 120-volt outlet, and includes a 12-foot power cord with a built in ground-fault circuit interrupter (GFCI) plug.
The tub holds up to 150 gallons of water, which is on the small side compared to other four-person tubs that hold 200 gallons or more. And, though advertised as a four-person tub, the product documentation clarifies that it seats two adults and two children, so four adults will find themselves far too cramped to use the tub at once.
The included heater and pump will heat water to a maximum temperature of 104 degrees Fahrenheit, which is standard; the U.S. Consumer Product Safety Commission recommends that hot tubs go no higher in temperature, though some models will go as high as 106 F to compensate for the rapid heat loss experienced by some poorly insulated inflatable models. With a heating rate of 2 to 3 degrees Fahrenheit per hour, the tub may take 12 hours (or more) to heat up to comfortable temperatures, so you’ll want to start it heating the night before you plan to use it. The air blower powers 88 bubble jets and can be used to inflate the tub during set-up.
The included top cover is made of the same tan synthetic leather as the exterior cover, with locking quick release latches securing it to the tub. For better heat retention, there’s an additional insulating solar blanket that you can put down before closing the top cover, but most inflatable hot tubs for sale have such insulation built into the cover instead of including it as a separate piece.
Additional accessories include a floating chemical dispenser, a chemical test strip kit, two filter cartridges, a ground mat and a patch kit for repairing punctures and tears. Blue Wave Products covers both the electrical components and the tub pool with 12-month warranties, which is something of a rarity among inflatable hot tub manufacturers, which usually cover the tub pool for a much shorter period.
The Blue Wave Radiant Saunas Simplicity 4-Person Inflatable Spa is a relatively affordable inflatable hot tub with a decent assortment of included accessories and a generous warranty. It’s also quite portable, though the small size and capacity may not be enough for some people.
