$399.00Cold plunge tubs from $760. The twentyfold spread to the top of the range is the decision: the cheapest is an inflatable ice bath you fill and drain, the dearest an insulated tub with its own chiller.
Chilled or filled
A chilled tub holds a set temperature and filters continuously. A filled tub costs nothing to run and takes a few minutes of icing each time. That single difference drives both the price and how often the tub actually gets used, and it is worth deciding before you look at anything else.
Most of what is out of stock with the supplier right now is chilled and mid-priced, so the gap in the range is the middle rather than either end.
Build
Thermo-treated wood and insulated shells are the common builds, with inflatables at the cheap end. Several units pair materials, putting a steel liner inside a wood surround. Ice Tubs and Dreampod supply about half the range between them.
Almost nothing here publishes an operating temperature range. Two units do. Ask for the figure on the specific model rather than assuming a tub reaches what you have read elsewhere.
Delivery
Free shipping to the lower 48, no minimum, and it stops at the curb — the crate is left at the end of your driveway. Getting it inside is a $600 white-glove upgrade. Getting it inside and assembled is $1,800, which covers everything except electrical work: we recommend you hire a local electrician for that, because the wiring has to meet your local code and pass local inspection. Service fees are non-refundable: if the sauna goes back, the installation does not.
