A 4 person inflatable hot tub is the sweet spot for most Canadian families — big enough for the whole household, compact enough to fit a standard backyard or deck without permanent installation. Every SaluSpa 4–5 person portable hot tub in this collection heats to 104°F, runs a powerful AirJet™ bubble massage system, and sets up in around 15 minutes with no tools. Built with DuraPlus Triple-Layer construction and Beam Support technology, these tubs hold their shape and pressure through years of regular use. Whether you’re after a round inflatable hot tub for relaxed family evenings or a square model with maximum seating, this range has a size and spec to match your space and budget.
