Comparison
Kuuma vs Nippa: which wood sauna stove should you buy?
Nippa's Legacy costs $196 to $696 less than Kuuma's Classic for the same room. The Kuuma carries a current UL listing and has its glass door in the price.
Buy the Kuuma Classic Legacy if your building department wants a listed stove or your hot room runs past about 512 cubic feet, where it costs less than $300 more than the matching Nippa. For a small room that needs no listing, the Nippa Legacy WB-15 saves you about $700. Kuuma builds its stoves in Tower, Minnesota, and Nippa builds the Legacy in Beulah, Michigan, and both makers say the steel is American. We paired the two lineups by room size using Kuuma's spec table, Nippa's Legacy manual and each maker's ordering terms.

Each Kuuma pairs with a Nippa rated for the same room
We matched every Kuuma Classic size with the Nippa Legacy rated for the same top room size. Nippa costs less at every step, and the gap narrows as the room grows.
Nippa also makes the WB-18 for rooms of 525 cubic feet at $1,999. It covers a touch more room than Kuuma's small Classic for $396 less.
| Room size | Kuuma Classic Legacy | Nippa Legacy | Nippa costs less by |
|---|---|---|---|
| Up to about 512 cu ft | Small, $2,395 (336–512 cu ft) | WB-15, $1,699 (400 cu ft) | $696 |
| About 512–780 cu ft | Medium, $2,595 (512–780 cu ft) | WB-21, $2,299 (775 cu ft) | $296 |
| About 780–1,000 cu ft | Large, $2,795 (780–1,000 cu ft) | WB-24, $2,599 (1,000 cu ft) | $196 |
Each maker's price for the stove alone and its own room rating, read Oct 10, 2026 and rechecked Oct 12. Kuuma rates each size for a range of rooms and Nippa gives one top size. Prices are before rocks, chimney, freight and sales tax.

The Kuuma's price covers the glass door and a current listing
Every Classic Legacy comes with a glass window in the door and an ashpan with a grate, and Kuuma takes $200 off if you'd rather have a solid door, per its Classic page. Nippa added a glass door to the Legacy as an option in June 2025, so its price goes up if you want to watch the fire.
PFS-TECO lists the Classic to UL 1482, the standard for solid-fuel room heaters, inspects the line quarterly and puts a serialized label on each stove, Kuuma says. Nippa posts UL 1482 test reports for three Legacy sizes from about 1980, and we couldn't find a current listing for the stoves it sells today.
If your county asks for a listed solid-fuel appliance, buy the Kuuma, or get a file number from Nippa in writing before you order.

The spec sheets part ways on weight and rock
A Kuuma is about twice as heavy as the Nippa for the same room, and its firebrick lining accounts for 48 to 64 pounds of the difference. You'll want a dolly and a second person for either one, and a Nippa WB-15 is the easier stove to carry through a barrel sauna's door.
The Kuuma holds 80 to 140 pounds of stone on the stove itself. Nippa sells rock as add-ons: a $250 body surround and a $300 stovepipe surround that cages about 150 pounds of stone around the flue. Nippa also says the Legacy burns coal or coke as well as wood.
| Kuuma Classic Legacy | Nippa Legacy | |
|---|---|---|
| Weight | 375–500 lb with firebrick | 192–248 lb |
| Rocks | 80–140 lb on the stove, sold separately | Body and stovepipe surrounds sold separately |
| Wood | Logs up to 16 in (21 in on the large) | Firebox 15–24 in deep |
| Glass door | Included | Optional |
| UL 1482 | Current listing by PFS-TECO | Test reports from about 1980 |
| Flue | 6 in, Class A chimney with no reducers | 6 in, lined masonry or approved insulated chimney |
| Front clearance | 48 in | 48 in |
| Side and back clearance without shields | 38 in sides, 28 in back | 36 in |
| Side clearance with shields | 7 in, with stove and wall shields | 7 in, with Nippa's heat shield |

The two warm-up times can't be compared
Kuuma says a well-insulated hot room reaches the desired temperature in about 45 to 60 minutes. Nippa says about 220°F (104°C) in 60 to 90 minutes, depending on the weather outside, per its Legacy page.
Neither maker gives a starting temperature, and Kuuma doesn't name a target, so these are two claims measured different ways.
Kuuma sells by quote and Nippa sells from a cart
Kuuma asks for a quote and a $1,000 non-refundable deposit, then ships on a pallet with lift-gate delivery to the curb for the actual freight plus $75, per its ordering page. Lead times run from several weeks to a few months, and paying by card adds 3%. You can also drive to Tower and pick the stove up.
Nippa's store takes the order online and works out tax and shipping at checkout, with a $100 charge for a palletized stove. Nippa doesn't publish a lead time, so ask before you plan a build around the delivery date.
Both stoves come out of the old sauna country of the Upper Midwest
Lamppa Manufacturing is a fourth-generation family shop in Tower, on Minnesota's Iron Range, and it says every Kuuma is built there from American steel. Leo Nippa founded his company in Bruce Crossing, in Michigan's Upper Peninsula, in 1930, and it moved to Beulah in 2005. Nippa's home page says its stoves are made from American steel, and the Legacy manual names Nippa LLC in Beulah as the maker.
Neither maker says where its door glass comes from. Our method page sorts stoves on the steel body, which both makers state.
Who should buy which?
Buy the Kuuma Classic Legacy for any build that goes through a permit, or for a hot room over about 512 cubic feet, where it costs under $300 more than the Nippa. Its price already includes the glass door.
A small backyard sauna in a county that doesn't ask for a listed stove is where the Nippa WB-15 or WB-18 makes the most sense. Put the $400 to $700 you save toward a good chimney. If you'd rather skip the woodpile altogether, our guide to sauna heaters built in the USA covers the electric side.
