PlungeDB is a small, independent site for people shopping for a home sauna or cold plunge. Most of these cost hundreds to tens of thousands of dollars, and the specs are spread across a dozen brand sites that each describe things differently.
We put the numbers in one table. Specs and prices come from each brand’s own product pages, and we note the date we checked them. When a brand doesn’t publish something, the cell stays blank. We don’t guess.
The site launched in October 2026 and is run by Kyle Raley. Right now it covers a handful of models. We plan to add more brands, keep a price history for each model, and send a weekly email when prices change.
