Frequently Asked Questions
What sizes do SaunaLife plunges come in?
The Soak series spans the compact S1 and S2 immersion tubs up to the larger S4 and S6, available as tubs or as complete tub-and-chiller packages.
Do I need to buy a chiller separately?
You can. Standalone tubs can be used with ice or your own chiller, while the 'C' package models (e.g. S1BC, S2NC) include a matched chiller for precise, on-demand cold.
How cold do they get?
With the chiller package you can dial in and hold true cold-plunge temperatures (typically the low 40s°F and below); exact range depends on the chiller and ambient conditions.
Can I use a plunge indoors and outdoors?
Yes. The tubs are built for both; just ensure a level, supported surface and, for chiller models, access to a suitable power supply and drainage.
What power does the chiller need?
Chiller packages run on a standard dedicated electrical supply; the exact requirement is listed with each package. A licensed electrician is recommended for permanent installs.
How do I keep the water clean?
Chiller packages include filtration; pair with simple sanitation and periodic water changes. Keeping a cover on between sessions reduces debris and maintenance.
How heavy are they when filled?
Filled plunges are heavy — always place them on a structurally sound, level surface (reinforced deck, pad or slab). Footprint and capacity are on each product page.
What about shipping and warranty?
Free freight within the contiguous U.S. with curbside delivery. Plunges and packages carry a 5-Year Residential Limited Warranty on the structure; accessories are excluded. Contact info@saunacompanyusa.com with questions.
