Why We Like It

The Empava 77" Smart Hot & Cold Plunge Tub offers a compelling combination of full-body immersion, app-based temperature control and both cooling and heating capability in a clean acrylic design.

Its 38°F–104°F temperature range allows the same unit to function as either a cold plunge or warm soaking tub without adding ice or a separate heater. We also like the generous 132-gallon capacity, integrated circulation and filtration, and straightforward plug-in setup.

For ZZC, this provides a more contemporary alternative to the cedar models while maintaining the premium, permanent-wellness-space aesthetic we're building.

Best For

Homeowners, fitness enthusiasts and active individuals looking for a full-size smart cold plunge with warm-soak capability and enough room for comfortable full-body immersion.

It's particularly appealing for a home gym, dedicated wellness room, garage or residential wellness space where precise and repeatable temperature settings are desirable.

• 77-inch format: Offers a more traditional reclined immersion position than upright barrel-style plunges.

• Plug-in installation: Manufacturer describes the unit as requiring no permanent plumbing and operating from a standard electrical outlet.

• Acrylic construction: Provides a smooth, contemporary hard-shell bathing surface.
• Insulated cover included: Helps protect the water and maintain temperature when the plunge isn't being used.

Things to Know Before Buying

Although the manufacturer describes this as a standard-outlet, plug-in system, the supplied information does not specify the actual voltage, amperage or circuit requirements. Buyers should verify those requirements and make sure the intended outlet and circuit comply with Empava's installation instructions before use.

The stated approximately 68 dB operating noise level should not be interpreted as silent operation. Actual perceived noise will depend on the installation environment and surrounding surfaces.

The supplied information also doesn't specify the system's chiller/heater power, cooling and heating times, dry weight or filled weight. With approximately 132 gallons of water, the filled unit will impose a substantial load on its supporting surface. Confirm the manufacturer's weight and foundation requirements before installation.
