While these terms are often used interchangeably, there are a few key differences to note. A hot tub is any large vat of water that can accommodate more than one person to relax and entertain and does not necessarily include jets. A spa refers to a hot tub that includes jets for therapeutic purposes. In contrast, a whirlpool tub is a bathtub with jets found inside a home’s bathroom (often the primary) rather than outside.

Hot tubs last five to 20 years, with inflatable models lasting up to seven years. If you opt for a high-quality, permanently installed tub made from durable materials and backed by a solid warranty, you can enjoy long-lasting performance. Professional installation and regular maintenance will help extend your hot tub's lifespan and protect your investment.

Popular hot tub brands include Arctic Spas, Bullfrog Spas, Cal Spas, Caldera Spas, Hot Spring Spas, and Viking Spas. These brands deliver exceptional quality and innovative features that suit a variety of design and performance preferences. Their products benefit from reliable engineering, superior energy efficiency, and extensive warranties reinforcing long-term satisfaction.

Hot tubs use electricity, which results in operating costs of $20 to $30 per month. Engineered components, including the heater wattage, size, and thermostat setting, determine energy consumption. Energy-efficient models with insulated covers, thermal blankets, and modern controls help reduce costs while maintaining performance. Regular upkeep and precise temperature settings optimize energy use and prolong your hot tub’s effectiveness.
