SaunaLife S2 Package Soak Series 2-Person Cold Plunge Tub with Chiller

Inside the tub

What two bathers actually get

The fiberglass insert is contoured rather than cylindrical, so the water sits around you instead of above your knees, and the matching steps come with it.

Inside the tub

Interior	66.5 × 39.1 in, 36 in deep (169 × 99 × 91 cm)
Exterior	74.4 × 46 × 41 in (189 × 117 × 104 cm)
Water capacity	200 gallons
Weight, empty	353 lbs (160.1 kg)
Weight, filled	About 2,022 lbs, before bathers
Steps	Round deluxe Thermo-Pine stairs, supplied
Lining	Contoured grey fiberglass insert

The number that decides where it goes is the filled weight, not the shipping weight. A tub holding 200 gallons carries most of a ton of water, so a lawn, a slab or a ground-level deck is straightforward and a raised deck or a balcony is a question for whoever built it.

The two-person shape is doing something the extra gallons alone do not. At 66.5 inches long the S2 lets one person lie back rather than sit upright, which is the difference between enduring a plunge and staying in it. Two people face each other instead of taking turns, which matters more than it sounds: couples and training partners who plunge together keep the habit, and the person who goes second is not waiting for a tub to pull its temperature back down.

The one choice you make

Natural or black

What the choice changes

Natural	Thermo-Pine in its own colour, which weathers to grey outdoors
Black	The same tub with the shell painted black at the factory
What does not change	Everything else. Same tub, same insert, same steps, same water capacity, same connections, same warranty

Choose the finish in the Finish control above Add to Cart. It is applied before the tub ships, so it is not something to change afterwards.

The decision that is already made

How your S2 Package holds temperature

Buying the tub on its own leaves one question open: what makes the water cold, and who matches it to 200 gallons. The Package answers it. The AP-1 is sized for this tub, connects to its built-in fittings, and runs from a standard outlet.

It is a chiller and a heater in the same box, so the same unit runs a cold plunge and a hot soak.

Because the unit circulates and filters, the water is not still between sessions the way it is in a tub run on ice. That is the practical difference most owners notice first: it is ready when you are, and it stays clear without being emptied as often.

What you still decide

Where the chiller stands. It wants a dry, ventilated spot within reach of the tub and of an outlet, close enough for the hose lines that come with it. Work that out before delivery day, because it decides where the tub goes as much as the tub does.

The tub still drains through its own 1 inch outlet, so you still need somewhere for 200 gallons to go when you change the water.

What 200 gallons means for the chiller: it is 60 per cent more water than the one-person package, so the first pull-down takes longer and the AP-1 runs more to hold a set point. The compensation is that a bigger body of water is more stable once it is there, and barely moves when two people get in, where a small tub warms noticeably around a single bather.

Scope

What you get, and what you also need

Two cartons: the tub assembled at 81.5 × 48 × 47.4 inches, and the chiller at 21.2 × 15.8 × 22.2 inches. Here is everything in them.

• The tub, fully assembledcontoured grey fiberglass insert in a Thermo-Pine shell
• Thermowood walls0.7 in thick (1.7 cm)
• Foundation beams3.94 × 3.94 in (10 × 10 cm)
• Round deluxe stairs
• Drainage1 in (3 cm)
• Chiller connections3/4 in (2 cm) NPT, threaded through the shell
• AP-1 chiller and heaterwith its LED remote
• Water hose linestub to chiller
• Filter assembly and filterwith a secondary filter screen
• Filter wrenchesmain and secondary
• Installation manualsone for the tub, one for the chiller

No cover comes with the Package. SaunaLife sells an insulated cover made for this tub, and it earns its place here more than it does on a tub run with ice: a cover is what stops the chiller working against the air all day.

Before you order

Five things to check before the S2 Package ships

None of these is hard. All of them are easier to answer now than on the day the pallet is standing in your driveway.

• Will the base carry it filled?About 2,022 pounds spread over 74.4 by 46 inches. On soil or a slab it is a non-question; over a raised deck or a balcony, ask whoever built it.
• Is it going where you can drain it?200 gallons has to go somewhere every time you change the water. A hose run to a drain or a part of the garden that can take it is worth deciding before the tub arrives, not after.
• Where will the chiller stand?It needs a dry, ventilated spot within reach of the tub for its hose lines, and a standard outlet. Deciding this late is what forces a tub to move after it is full.
• Can the pallet reach the spot?The tub arrives assembled at 81.5 by 48 by 47.4 inches, with the chiller in its own carton, 516 pounds together. The tub does not come apart, so gates, steps and turns are measured against it, not the box.
• Is it level?A tub that is not level fills unevenly and drains badly. The foundation beams in the kit sit on what you prepare, so the preparation is where level is won.

Placement

Setting the SaunaLife S2 Package down

There is no build. The work is the base, the chiller's hose lines and the water.

Set the foundation beams on a level, drained base and the tub on them. Stand the chiller where it will live, run its hose lines onto the 3/4 inch fittings, plug it in, then fill by hose. From delivery to first plunge is an afternoon, most of which is filling and pulling the temperature down.

After the sale

Who stands behind the S2 Package, and for how long

Two companies stand behind this package: SaunaLife for the tub, and the chiller's own manufacturer for the chiller. Both are written warranties on their own terms.

Wood moves. Knots, grain and tone differences, and shrinkage and swelling with temperature and humidity, are normal in a timber shell and sit outside the warranty on any brand. Keep your delivery receipt with the warranty and a claim takes one phone call.

Construction

What the S2 Package is made of

Two materials, each doing one job. The water sits in a moulded fiberglass insert, which is what makes the inside smooth, contoured and easy to wipe out. The shell around it is Thermo-Pine, which is what makes the outside survive a garden.

Thermally modified timber. Heat and steam drive the moisture and resin out of the wood, which leaves it dimensionally stable and far more resistant to moisture, decay and fungi than untreated softwood. SaunaLife says it lasts up to twice as long as cedar.

Built at the factory, not in your garden. The insert, the shell and the fittings are assembled before it ships, which is why there is nothing to build and why the chiller connections are already through the wall rather than something you drill.

The real comparison

The S2 Package against the other ways to buy this tub

The S2 Package is cross-shopped against two things: the same tub without a chiller, which is cheaper and runs on ice, and the S1 Package, which is the one-person version with its own chiller. The two chillers are different units with different ranges.

	SaunaLifeS2 PackageYou are here	SaunaLifeS2 tub only	SaunaLifeS1 Package
Bathers, up to	2	2	1
Water capacity	200 gallons	200 gallons	124 gallons
Chiller	AP-1, included	Not included	FDC-1A, included
Temperature range	37 to 107°F	Whatever the ice holds	32.5 to 108°F
Filtration	Ozone, built into the chiller	None	Ozone, built into the chiller
Weight, filled	About 2,022 lbs	About 2,022 lbs	About 1,159 lbs
Shipping weight	516 lbs	396 lbs	390 lbs

Choose the Package when you want 200 gallons cold on demand without sizing and sourcing a chiller yourself, or when hot soaking matters as much as cold. Choose the tub alone when ice suits you or you already own a chiller. Choose the S1 Package when it is only ever one person: a smaller fill is quicker to cool and cheaper to hold.
