Aspen Spas Northstar 5-Person Round Hot Tub – 81 in., 24 or 30 Jets, 110V or 220V, Made in USA

Compact comfort in a classic round shell. The Northstar seats five adults in an 81-inch circle — small enough for a patio, a deck corner or a courtyard, deep enough that nobody is sitting with their shoulders out of the water.

Designed and built in St. Louis, Missouri. Aspen Spas has been manufacturing in the USA since 1991.

Seating

• 1 captain's chair — contoured, the seat people claim first
• 4 bench seats
• Step entry and a spacious, deep footwell so five people aren't fighting for legroom

Choose your power before you choose anything else

• 110V — plugs into a standard outlet. No electrician, no permit, no dedicated circuit to run. Heating is slower, and the heater and jets share power rather than running flat out together. Available on the Value Series.
• 220V — hard-wired to a dedicated circuit by a licensed electrician, with a GFCI disconnect and usually a permit and inspection. Faster heating and full output. Required for the Great Series, and available on the Value Series.

Confirm the amperage for your chosen configuration with us before booking any electrical work.

Two series

Value Series (VS) — 110V or 220V

• 24 hydrotherapy jets
• 1 therapy pump
• Gecko in.k300 digital control
• 3.5" LED mood lighting
• Gecko in.touch Wi-Fi app — optional

Great Series (GS) — 220V

• 30 hydrotherapy jets
• 1 therapy pump
• Gecko in.k506 touchscreen control
• Gecko in.touch Wi-Fi app included — set temperature and check the spa from your phone
• Multi-colour mini LED lighting

On both series

• 2 Roman fountains
• Ozone water purifier
• 50 sq ft filter system
• Optional 24-hour circulation pump — worth considering: without it, filtration and heating run on the therapy pump, so the main pump cycles more often

Gecko is one of the industry's principal spa control manufacturers, so parts and service are widely available.

Siting and delivery
Filled and occupied the spa weighs around 4,100 lb across roughly 36 square feet — about 114 lb per square foot. It needs a level base built to the specification in Aspen's owner's manual; do not place it on a deck, balcony or raised structure without a structural engineer's assessment. Leave service access to the equipment bay. At 81 inches across and 600 lb dry it will not pass through a standard gateway — confirm the delivery route, corners and turning radius before ordering.

Warranty and support
Covered by Aspen Spas' limited warranty for the series you choose; registration is required. Our team can help with questions about setup, operation and maintenance.

Ideal for

• Compact backyards, patios and decks
• Couples and small families, or soaking solo
• Anyone who wants a spa without running new 220V service — choose the 110V Value Series

Before you use it
Hot water immersion carries real risks. Keep the water at or below 104°F, limit soaks to 15–20 minutes, and get out if you feel dizzy, drowsy or nauseated. Do not use alcohol or drugs before or during a soak. Talk to your doctor first if you are pregnant or have a heart condition, high blood pressure, circulatory problems or diabetes. Children overheat much faster than adults and must be closely supervised. Keep the spa covered and secured whenever unattended — an uncovered spa is a drowning hazard. Never soak alone, and keep electrical appliances away from the water.
