Barrel saunas are the most popular outdoor sauna shape, and they’re sold in two very different ways: some ship ready to heat, others ship as an empty barrel and leave the heater to you. That second group also opens the door to wood-burning heat.
This article covers the total cost of a barrel sauna once it’s heated, electric or wood-burning. For the wider traditional sauna decisions, start with the traditional sauna buying guide.
Short answer: add the heater, the wiring or chimney, and the base to every barrel’s price before you compare. An electric barrel needs a 240V outdoor circuit; a wood-burning one needs a chimney and firewood instead.
Which barrels include a heater
| Barrel | Price (Select Saunas, Oct. 1, 2026) | Heater | Warranty (per listing) |
|---|---|---|---|
| Almost Heaven Salem (2 people) | $4,176 | 6kW included | Limited lifetime (cabin) |
| Almost Heaven Grandview (4–6 people) | $6,358 | 8kW Harvia KIP included | Limited lifetime (manufacturing defects) |
| Canadian Timber Harmony (2–4 people) | $5,977 | Not included; 8kW electric recommended, or wood | 3-year parts only |
| SaunaLife Ergo E7 (4 people) | $5,190 | Not included; electric or wood | Limited lifetime (original purchaser) |
The Harmony and E7 look close to the Grandview on price. Once you add a heater, they aren’t.
The electric route
You get convenience with electric heat: a timer, a steady temperature, and no firewood. You give up an easy install. A detached barrel needs a 240V circuit run from your panel, which a 2026 installer guide puts at about $1,500–3,800 for 25–75 feet.
Larger heaters need heavier wiring. Harvia’s KIP manual lists 33.3 amps and #8 wire for the 8kW model, versus 25 amps and #10 wire for the 6kW.
The wood-burning route
You get independence from the grid and the crackle of a real fire. You give up simplicity.
Harvia’s M3 stove, a common choice for barrels, is rated at 16.5kW for rooms of 212–459 cubic feet and holds 66.2 lbs of stones. It needs 11.81 inches of clearance to combustible materials on the front, sides, and back, and 3.94 feet to the ceiling. You’ll also need a chimney and a supply of dry firewood.
Here’s what the spec sheet won’t tell you: some barrels sell a wood-burning kit as a separate package, and the chimney may be extra. Price the full kit before you compare.
Don’t forget the base
Every barrel needs a level base: a concrete slab, flagstone, a wooden platform, pavers, or compressed gravel, never bare earth (Almost Heaven). Budget for it whichever heater you choose.
Which way to go
My rule of thumb: if you have power within easy reach and want to sauna on short notice, go electric. If the barrel will sit far from the house or you love a wood fire, go wood-burning and budget for the chimney.

Bottom line: compare barrels on the heated, installed price. The cheapest empty barrel is rarely the cheapest working sauna.
