Quick Answer: Superior Saunas is a Northern Wisconsin kit-and-parts retailer, not a sauna brand — its actual lineup is Finnish IKI electric and wood-burning heaters ($2,278-$3,680), prefab outdoor cabin/pod kits, Thermory Mod4 panel kits bundled with an IKI stove ($9,600-$10,500), and custom liner materials (paneling, bench stock, flooring) priced by the square foot. The genuine differentiator is IKI’s heater design: an open, stainless-mesh stone frame that exposes the stones on all sides rather than hiding them under a closed top like the Harvia units this site typically defaults to, which changes how — and how long — the steam behaves once the stones are hot.
“Superior sauna” gets searched often enough that it’s worth being precise about what the name actually refers to here: not a generic adjective, but Superior Saunas, a real Ashland, WI retailer this site has already cited twice for materials pricing. Here’s the full product lineup, what’s genuinely different about it, and where it overlaps with brands already covered on this site.
What’s actually in Superior Saunas’ catalog
| Category | Examples | Price range |
|---|---|---|
| IKI electric heaters | Pillar 6kW/9kW, Corner 6kW/9kW | $2,278-$2,790 |
| IKI wood-burning heaters | Mini-Plus, Original, Original Plus | $2,490-$3,680 |
| Thermory Mod4 kits (w/ IKI stove) | Traditional layout, Modern layout | $9,600-$10,500 |
| Outdoor cabin/pod kits | 5x7, 6x6, 6x7 cabins; 8x8 pod | Varies by size |
| Liner paneling (per sq ft) | White Aspen, Western Red Cedar, Finnish Spruce | ~$16-20/sq ft (cedar) |
| Flooring tile (per sq ft) | Red Cedar duckboard, Ipe hardwood | ~$35/sq ft (cedar) |
That’s a materially different business than Dynamic, Maxxus, or Golden Designs — the dealer-distributed infrared-cabin brands this site covers most. Superior Saunas doesn’t sell a branded infrared cabin at all; it sells the Finnish heater hardware and raw build materials that go into a traditional sauna, whether that’s a prefab kit it ships or a DIY build using its own cedar and spruce stock.
IKI’s open-mesh heaters: a real design difference, not a rebrand
IKI Kiuas has built heaters by hand in Pieksämäki, Finland since 1997, and the thing that sets its lineup apart from the Harvia heaters this site’s best sauna heater guide defaults to is structural, not cosmetic. IKI’s signature build uses a stainless-steel mesh frame that leaves the stones exposed on every side instead of enclosing them under a solid top — which means water can be thrown onto the sides of the stone mass, not just the top, per IKI’s own product materials. The largest wood-burning model in the lineup, the Original Plus, holds up to 660 lbs of stones, a notably larger stone mass than most closed-top electric units this site has reviewed, which IKI states produces a softer, longer-duration steam release once the sauna is up to temperature.
That’s worth flagging because “sauna heater” isn’t a single interchangeable part — the enclosure design changes how löyly behaves, independent of kW rating or stone weight alone. Anyone shopping Superior Saunas’ IKI lineup specifically for the steam quality, rather than just a heat source, is paying for that open-mesh design, not just a different badge on a familiar box.
Wood-Burning Sauna Heater (Amazon)
- IKI's wood-burning line isn't sold on Amazon — Superior Saunas and other specialty dealers are the direct channel — but comparable wood-fired heaters with visible-stone designs are available here with standard shipping.
- Worth comparing stone capacity and enclosure style directly against the IKI Original/Original Plus specs above before assuming "wood-burning heater" means the same steam behavior across brands.

The Thermory Mod4 kit: a different channel, not a different company
This site’s Thermory review already covers the 50 Series ($5,066-$6,935) and 60 Series ($6,797-$7,492) — prebuilt barrel saunas Thermory ships direct under its own name from a US warehouse. Superior Saunas carries a separate Thermory product: the Mod4, a modular panel kit built from the same thermally modified Nordic spruce, sold through third-party kit retailers rather than direct, and bundled here specifically with an IKI stove at $9,600 for the Traditional layout or $10,500 for the Modern layout.
The wood and the manufacturer are the same; the channel and the assembly format aren’t. A buyer comparing Thermory’s own 50/60 Series pricing against the Mod4 kit price at Superior Saunas isn’t comparing two prices for the same product — the Mod4 is a DIY-assembled kit sold with a specific heater bundled in, not the prebuilt barrel Thermory ships itself.
Sauna Heater Stones (Amazon)
- Whether running an IKI, Harvia, or any other open or closed-frame heater, stone quality and shape affect steam quality as much as the heater housing does.
- A practical add-on for anyone building from Superior Saunas' liner kits and sourcing the heater separately.
Liner materials: the part this site has already price-checked twice
Superior Saunas shows up on this site already, just not as its own page. Our sauna wood types guide cites its sauna-grade cedar tongue-and-groove paneling at roughly $16-20/sq ft, and our sauna flooring guide cites its Red Cedar duckboard at $34.95/sq ft — both notably higher than big-box lumberyard cedar, since sauna-grade milling, tighter tongue-and-groove tolerances, and clear (knot-free) grading cost more than construction-grade stock. That pricing is consistent with a retailer whose core business is specialty materials sold by the square foot, not volume-discounted lumber.
The bottom line
Superior Saunas isn’t a cabin brand to cross-shop against Dynamic or Maxxus — it’s a Wisconsin kit-and-parts retailer whose real draw is Finnish IKI heaters (open-mesh stone design, genuinely different steam behavior than closed-top Harvia units) and Thermory Mod4 panel kits bundled with an IKI stove, on top of the cedar and spruce liner stock this site has already price-verified twice. If an open-stone heater’s steam quality matters more than brand recognition, this is a legitimate specialty channel; if a turnkey prebuilt infrared cabin is the goal, this site’s best infrared sauna pillar is the better starting point.
