Hot tubs have become a popular addition to backyards, patios, decks, and dedicated outdoor relaxation spaces. For shoppers comparing spa prices in 2026, Costco has a broad selection covering compact two-person spas, four-person plug-and-play models, larger family spas, and premium acrylic tubs.
The current Costco online selection includes brands such as Aquaterra Spas and Evolution by Strong Spas, along with different construction styles and capacities. Current listings show models ranging from roughly $3,000 for smaller rotomolded spas to nearly $9,000 for larger acrylic spas, with promotional discounts appearing on selected models.
Because hot tubs represent a substantial purchase, the lowest listed price is only one part of the calculation. Size, electrical requirements, installation, insulation, jet configuration, maintenance, warranty terms, delivery, and long-term servicing can all affect the overall cost.
Costco's current hot tub category includes more than two dozen hot tubs and spas, with pricing spread across several levels. The selection includes compact models for couples, medium-sized tubs for families, and larger luxury spas designed for frequent entertaining.
Some examples from the current 2026 Costco selection include:
Prices and promotions can change, so the exact amount shown on a product page can differ from earlier listings.
A two-person spa can make sense when the primary purpose is relaxation rather than entertaining a large group.
The Evolution by Strong Spas Refresh is one example in Costco's current lineup. It has 22 jets, rotomolded construction, and a plug-and-play configuration. Its smaller footprint can make it easier to consider for patios and limited outdoor spaces.
Smaller tubs can also reduce water usage compared with larger seven-person models. However, the footprint should not be the only measurement considered.
Access to the installation location is important. A backyard may have enough space for a hot tub but still lack a practical route for moving a large spa from the delivery point to the final location.
Four-person spas sit between compact two-person tubs and large family models.
The Aquaterra Spas Benicia is one example currently listed at Costco. It has 20 jets, four-person capacity, rotomolded construction, and a plug-and-play configuration.
This category can be appealing for households that want more seating without paying for a much larger tub.
Before selecting a four-person spa, it is worth checking the interior seating arrangement rather than relying only on the stated capacity. A "four-person" rating describes the manufacturer's intended capacity, but individual seat dimensions and legroom can vary considerably.
Larger spas can be useful for families, frequent guests, and outdoor entertaining.
Costco currently lists several six- and seven-person models, including the Aquaterra Montecito, Evolution Adventure, Evolution Oxford, and Evolution Stockbridge.
The Evolution Oxford, for example, has 121 jets and a seven-person rating, while the Stockbridge has 95 jets and a six- or seven-person rating. These models sit toward the higher end of Costco's current hot tub pricing.
Larger spas also require more attention to placement, electrical service, water volume, foundation strength, and ongoing energy consumption.
One of the most important differences between Costco hot tubs is construction.
Acrylic spas generally have a more traditional premium-spa appearance. They can feature molded seating, larger jet configurations, lighting, waterfalls, sound systems, and more elaborate cabinet designs.
Costco's current listings include acrylic models from both Aquaterra Spas and Evolution by Strong Spas.
Rotomolded tubs are made using a rotational molding process. They are often simpler in appearance and can be lighter or easier to position than some large acrylic models.
Several Costco models use rotomolded construction, including the Benicia, Montecito, Adventure, and Refresh.
For shoppers comparing prices, rotomolded construction can represent a lower-cost route into hot-tub ownership.
Plug-and-play is another important term appearing in Costco's listings.
A plug-and-play configuration generally means the spa is designed around a simpler electrical setup than many permanently wired installations. Several current Costco models, including the Benicia, Adventure, and Refresh, are identified as plug-and-play.
That does not mean every installation is completely effortless.
The electrical requirements should be reviewed before purchase. The location also needs an appropriate surface, drainage considerations, safe electrical access, and sufficient clearance around the spa.
Local electrical requirements can vary, so professional installation may still be appropriate.
A discounted price can make a hot tub more attractive, but several other factors deserve attention.
A seven-person spa can look appealing because of its capacity, but a smaller household may get more value from a compact model.
Larger tubs generally require more water, more energy, more floor space, and more maintenance.
Before purchasing, measure the intended area carefully.
Consider:
A hot tub should not be purchased based solely on the dimensions of the tub itself.
Electrical requirements can differ considerably between models.
Some plug-and-play models are designed for simpler electrical connections, while larger spas may require dedicated electrical circuits and professional installation.
Understanding the electrical requirements before purchase can prevent unexpected installation costs.
A full-size spa is heavy and difficult to move manually.
Delivery arrangements should be reviewed carefully, including where the unit will be placed and whether additional equipment or labor is required to move it from the delivery point to the final installation area.
Costco periodically displays promotional discounts on selected hot tubs.
Current listings provide several examples. The Aquaterra Huntley is displayed at $4,999.99 after a $2,000 discount, while the Evolution Oxford is displayed at $7,999.99 after a $2,000 discount. The Evolution Adventure is shown at $3,599.99 after a $1,000 discount.
These promotions demonstrate why checking the final product-page price can be important.
A model that initially appears expensive may become considerably more competitive during a promotional period.
However, a discount should be evaluated against the complete purchase and installation cost rather than treated as the primary reason to select a particular spa.
The listed price is only the beginning of hot-tub ownership.
Potential additional expenses include:
The long-term operating cost can vary depending on climate, insulation, water temperature, usage frequency, and electricity rates.
Hot tubs maintain warm water continuously or for extended periods, which means insulation can have a meaningful effect on operating costs.
A well-insulated cabinet and high-quality cover can help reduce heat loss.
Climate also matters. A spa operating through a cold winter may require substantially more energy than one used primarily during mild weather.
When comparing models, specifications concerning insulation, cover construction, pumps, heating systems, and energy-saving features can therefore be just as important as the jet count.
