Not only is M-SPA's inflatable Silver Cloud Bubble Spa (uh, I think they'd sell more just calling it a bow-up hot tub) significantly less expensive than a permanent installation, but according to Amazon reviewers, you can install it both outdoors and in. Hot Tub in the yard, hot tub on the deck, or...hot tub in the living room? Ahhh, hot water therapy, affordable luxury, and immediate proximity to the Xbox. I'm so glad I don't live in the olden days.

The M-SPA inflatable hot tub is made of 3-layer laminated PVC with a base and walls forged to sustain 184 gallons of water. Despite its seemingly on-the-cheap nature, the spa does have mechanical components, including a pump and filter, built-in control box with touch buttons for operating its air bubble jets, and a 675-watt heater capable of warming water to temperatures of 104 degrees F. The hot tub package also comes with a cover.
