Choose if	You want an all-in-one chilled tub for home use, indoors or out, and you have a dedicated 120 V, 15 A circuit and a floor that can take 1,150 lb.	You want cold plunges and warm soaks in one lay-back tub, carried into the room for you, and you have a spare dedicated 15 A circuit.
Main trade-off	The price depends on a time-limited sale, the base warranty is one year, and running costs are unknown because the product page gives no power draw.	At $10,990 you get 2 years of coverage unless you pay $1,299 or more for Chill+, and once you fill it or plug it in, you can't return it.

Exact variant	Gen 2, Cold Only (no heater add-on)	Black, Standard size (67 in), 1.0 HP ChillX chiller
Dimensions	Plunge lists the tub at 76.75 L × 31.5 W × 28.75 H in. It weighs 238 lb empty and 1,150 lb filled. Plunge asks for at least 16 in of clearance on the fan side for ventilation. It also wants 12 in at the front for drain access and ventilation, and 4 in on the left side as you face the LED display. Plunge doesn't state interior dimensions.	The Standard cold plunge measures 67 in long, 31.5 in wide and 23.5 in high. Polar Monkeys gives a total footprint of 80 in long at the same width and height. The XL is 71 in long, or 84 in for its total footprint. The spec list gives a capacity of 85 gallons (322 L), but the store description says 80 gallons. The tub weighs 110 lb empty and 819 lb filled. Polar Monkeys says the Standard size suits most people up to 6'2" and suggests the XL for taller users. Interior dimensions aren't stated.
Installation	It needs a dedicated 120 V, 15 A circuit. A 7 ft power cord with a GFCI on the end is built in. There's no plumbing: Plunge says all you need to do is fill it with water and plug it in. Standard delivery is curbside, to the driveway or curb. Most customers qualify for free in-home delivery in Plunge's core "In Area" zones. It puts the tub on the first level, unpacks it and removes the packaging. Setup and connection to power aren't included. In-stock units ship within 8 business days in the lower 48 states. Hawaii, Alaska and US territories take an additional 2 to 3 weeks.	The user guide calls for a dedicated 120 V, 15 A circuit with GFCI protection. You must use the GFCI extension that comes with it and no other extension cord. The product page's spec list says 110 V, though its FAQ says 120 V. Polar Monkeys calls it plug-and-play with no plumbing. You fill it with a garden hose to 8 to 9 in below the rim, using the included hose filter. You empty it through a built-in drain valve or side drainage. The chiller weighs 76 lb and needs 12 in of clearance on its left and right. The standard hoses reach 6 ft, and longer runs need custom hoses from Polar Monkeys. The guide asks for a level, solid, water-resistant surface that can hold the filled tub, ideally in shade. It gives no floor-load figure. Below 33.8°F ambient you switch to heating mode. Below 25°F you drain the tub and bring the chiller indoors. White-glove delivery in the continental US is included: the crew places the tub in the room you choose, unboxes it and removes the packaging. Installation isn't included. The product page says it ships the next business day.
Materials	Plunge says it's built for indoor and outdoor use, and an insulated cover is included. Plunge doesn't say what the tub or shell is made of.	The tub is fully insulated acrylic. Polar Monkeys doesn't name the insulation material. Black and White cost the same, and the four printed finishes cost $600 more. Polar Monkeys says custom artwork, logos and colorways are available on request. Included items are an insulated cover, two filters, an ergonomic pillow, a phone holder, a hose filter and a skimmer net. The warranty page says the systems are assembled and serviced in the USA.
Warranty	The standard warranty is 1 year. During the Fall Plunge Sale, Plunge adds a complimentary 2-year extended warranty, which it values at $299. The product page doesn't give coverage details or exclusions.	It comes with a 2-year limited warranty covering defects in materials and workmanship, counted from the original purchase date. Coverage is for the original purchaser only, with proof of purchase, and it isn't transferable. The product page says the Brainpod is for residential use only, and the warranty excludes a residential unit used commercially. Other exclusions include misuse, improper installation, freezing conditions, power outages, and poor water chemistry or filter care. Enclosing the chiller in a box or cabinet that restricts airflow is excluded too. Third-party filters void it, and so does any modification, even a cosmetic one. You must claim within 30 days of finding a defect, by email with photos and videos. Standard claims carry no shipping fee in the continental US. In-home repairs are covered only up to a pre-approved amount. Chill+ 3-Year costs $1,299 and Chill+ 5-Year costs $1,899. You can buy either only when you buy the tub. Claims under an extended warranty carry a flat $299 shipping and handling fee for residential units.
Returns	Plunge offers a 30-day guarantee. It says that if you're not 100% satisfied within the first 30 days, you get a hassle-free return policy, though "some conditions may apply". The product page doesn't state return fees or pickup costs.	You can ask for a refund within 30 days of delivery. The refund policy is strict: the tub must be unused, unfilled, never plugged in and never operated. So you can't fill it to try it and then send it back. Polar Monkeys decides whether a return qualifies, and its decision is final. A 25% restocking fee applies, which is $2,747.50 on a $10,990 tub. That fee covers return shipping within the continental US. Canceling an order after it's placed costs 5%. Accessories, supplies and consumables can't be returned, and any modification voids both return eligibility and the warranty. The policy doesn't say how long a refund takes.
