Waterproof Speakers: You can’t bring your smartphone to the tub, but you can still listen to your favorite music while bathing in your tub and, likewise, keep answering and making calls whenever you need through the waterproof Bluetooth speakers. These little guys are a great addition for showering, bathing and swimming, you can finally set the party in the hot tub with loud music and keep your fix on your cellphone.

They don’t usually use real water jets, but instead use fans to “blow” the air around (also because of the 120 volt outlet), which causes them to cool down much faster than a regular hot tub. This cooling effect is only made worse by the fact that the materials they are made from lose heat much faster than the materials used on a regular hot tub. All in all, you aren’t likely to get more than 15 minutes to a half an hour of good heat out of an inflatable hot tub.
