Site prep and electrical: getting ready for your sauna
The saunas we sell assemble in a weekend — but the site work happens before delivery, and doing it right is the difference between an easy build and a frustrating one. Here's the complete pre-arrival checklist.
The base: level is everything
Every sauna needs a level, load-bearing base slightly larger than its footprint. Good options, cheapest first: compacted gravel (4–6 inches, with a perimeter to hold it) · concrete patio pavers on a sand bed — the most popular choice · a poured concrete pad — permanent and perfect · an existing deck, if it can carry the load (a filled 6-person barrel with bathers approaches 4,000 lbs — have a builder confirm joist capacity; rooftop decks need an engineer). Grass and bare soil are not a base: the sauna settles unevenly, doors rack, and staves stress.
Placement: think about the walk
The most-used saunas are the closest ones. Twenty steps from the back door beats fifty yards of garden path in January, every time. Leave a couple of feet of access around the structure for band tightening and staining, keep the door swing clear, and think about the view from the bench window — you'll spend hundreds of hours looking at it. Pair with a cold plunge? Put them within a few steps of each other and leave splash room (our contrast therapy guide covers layouts).
Electrical for electric heaters
Electric sauna heaters run on a dedicated 240V circuit — like an electric range or car charger — installed by a licensed electrician. The breaker and wire size depend on the heater's kilowatts (a 6KW heater typically wants a 30-amp circuit; 8–9KW wants 40; your electrician sizes it to code from the heater's spec sheet, which we provide with every quote). Cost scales with distance from your panel: a sauna near the house is often a few hundred dollars; a long trench run can reach $1,500. Get the electrician's quote before you order — it occasionally changes which heater, or which heat source, makes sense.
Wood stoves: clearance and chimney
Wood-burning models need no wiring, but they do need a chimney kit (through the roof or out the side — $701–$924 depending on routing) and respect for clearances around the stove, which the included heat shields and installation guides spell out. Check whether your municipality or HOA has rules about solid-fuel appliances; most rural and suburban areas are fine, some dense neighborhoods aren't.
Permits: usually easy, occasionally required
Small accessory structures often fall under permit thresholds (commonly 100–200 sq ft depending on the town), and a barrel sauna's footprint usually qualifies — but rules vary, and electrical work is typically permitted separately by your electrician. One call to your building department with the spec sheet in hand settles it; we're happy to supply drawings and specs that make that call painless.
The pre-delivery checklist
① Base built and checked level · ② offload plan arranged (see the delivery guide — this is the big one) · ③ electrician booked, or chimney routing chosen · ④ path from curb to site walkable with heavy boxes · ⑤ permit question answered. Do these five things and assembly weekend is genuinely fun — cedar, hardware, and a cold drink at the end.
