Our Thermory Review
Thermory is the rare barrel-kit brand where the manufacturer actually mills the wood, and thermally modified spruce is a real durability upgrade over the cedar and hemlock most kits use. Dealer prices from $5,296 undercut premium US cedar barrels while shipping with HUUM Wi-Fi heaters. The weak points are a two-year sauna warranty governed by Estonian law, quote-only pricing on Thermory's own channels, and a Mod line where some builds come from a US partner factory rather than Estonia. Buy through a dealer with published prices and confirm which factory built your model.
US dealer prices checked 2026-08-18: barrel sauna kits from $5,296 (No. 55 Natural at Superior Saunas) up to about $10,400 in the Ignite finish, Sauna Squares and Mod cabins at $9,200 to $14,900, and the Luik CLT cabin at $29,500 to $36,975 at The Sauna Place. Thermory's own sauna site is quote-only. Barrels and Sauna Squares include a HUUM heater; the Luik does not.

Strengths & Considerations
Strengths
- +The same company produces the thermally modified wood, with 13 production units in Northern Europe and a scale corroborated by investor reporting of over EUR 100 million in turnover.
- +Thermally modified Nordic spruce resists rot and moisture better than the untreated cedar or hemlock in most kits, and retailers market these as the only thermally modified barrel saunas in North America.
- +Barrel and Sauna Square kits include Estonian HUUM Wi-Fi heaters, which carry a five-year heater warranty.
- +Established US entity in Batavia, New York, a dealer network across more than 20 states, and published installation guides for every model.
- +Kit pricing from $5,296 undercuts premium North American cedar barrel brands.
Be aware of
- −The sauna warranty is two years, excludes the heater, glass and electrical parts, requires defect notice within 10 days, and is governed by Estonian law even for US buyers.
- −No prices on Thermory's own sauna site, and even heaters in its own web store say email for pricing. Real numbers only exist at dealers.
- −Mod branding is muddy: Superior Saunas builds its Mod 6 line in Wisconsin from Thermory materials and sells it under the Thermory name, so factory origin differs by retailer.
- −Thin independent review base. Buyers on r/Sauna note there are virtually no reviews or customer images online.
Before You Buy: Confirm These
These are Thermory's own documented terms and open questions, not our own test results. Confirm the specifics in writing before you order.
- ?Ask which factory built the specific model you are quoted. Estonian-built and US-partner-built units share the Thermory name.
- ?Report any defect fast. The sauna warranty requires written notice within 10 days of discovery.
- ?Buying materials rather than a kit? The wood warranty covers only decay fungi, pays out on a sliding scale, and is void unless you register within 90 days of purchase.
- ?The Luik cabin ships without a heater. Add the price of a HUUM or Homecraft unit plus an electrician to the sticker price.

Methodology
Brand verdicts are based on buyer fit, heater ecosystem, support path, price pressure, and the risks that tend to show up after delivery. A strong reply from a manufacturer can improve factual clarity, but it does not improve placement.
If support coverage, warranty language, or dealer access are thin, we would rather say that plainly than hide it behind marketing copy.
