What it is
A six-person Finnish barrel sauna in Northern European spruce, supplied as a pre-cut kit with an 8kW Harvia Spirit electric heater included. With no front terrace taking up cabin length, the Vassa uses its full 94.49-inch exterior footprint for the sauna room itself — the longest heated interior in this four-model collection.
Who it's for
A household that would rather have bench length and group seating than an attached cooling terrace. The heated room is 86.61 inches long with two-tier benches running 86.22 inches, which is more usable sauna-room length than the six-person Turku terrace model.
It is an outdoor building on a permanent foundation, hardwired to a 240V circuit. It is not a thing you move once it is built.
Built to order — approximately 4 to 8 weeks.
This sauna is not held in finished stock. It is built after your order is confirmed. The manufacturer gives a window of roughly four to eight weeks from order confirmation, and we publish the range rather than the best case so you can plan around it. If the timeline moves, we will tell you.
Working to a deadline — a season, an install date, a contractor booked? Call 866-427-8202 before ordering and we will confirm the current build time.
Because it is built to order, this sauna is not returnable.
The manufacturer's published policy treats products crafted specifically to order as non-returnable, with a 24-hour cancellation window from order placement. After that window a restocking fee of 35% of the purchase price applies, and return shipping is deducted from any refund.
On a sauna at this price that is a figure worth saying out loud rather than burying. If you are not certain, call us before you order, not after. We confirm the exact terms with the manufacturer on every order.

What electrical work does it need?
The manufacturer publishes 240V single phase, 60Hz, 33 amps, 8-gauge copper for the Harvia Spirit 8kW. It is UL Listed and must be hardwired by a licensed electrician following the supplied manual and local electrical code.
The 33 amps is the heater's draw. Your electrician determines the final breaker size for your specific run — we publish the manufacturer's figures rather than a number we worked out ourselves. Send us a photo of your panel before ordering and we will talk it through.
What does it stand on?
A flat, load-bearing foundation. The manufacturer specifies a slab of approximately 1880 × 1880 mm (about 6 ft 2 in square), or strip foundations at 940 mm spacing. Bare soil and grass are not foundations.
Anchoring is the owner's responsibility. Strong winds exert real force on a garden building, and the manufacturer does not accept liability for damage caused by inadequate anchoring. Plan the base before you order — it takes longer to arrange than the delivery does.
How hard is the assembly?
It ships as a pre-cut kit with no field cutting required. The manufacturer states you need basic manual skills and an assistant — a minimum of two people. All screw fittings must be pre-drilled.
Tools you supply: hammer with a wooden block and mallet, cordless screwdriver with cross-head and Torx bits, tape measure, drill bits (4, 5, 6 and 20–30 mm for the heater cable), spirit level, and an open-ended spanner.
What do I have to do to the wood?
The exterior arrives untreated. The manufacturer recommends painting or staining the outside with a suitable product to protect it and extend its life — that is the owner's job, not something done at the factory. The interior must not be treated with any paint or finish.
Wood is a natural material that swells, shrinks and can warp. Some force may be needed during assembly, and the colour will change over the first year or two. That weathering is normal and is not a defect.
Is it watertight?
No — a barrel sauna is not 100% watertight. Rain can enter, which is why two drain holes are pre-drilled in the lowest stave. These must be left clear so water can escape.
Condensation can stain the wood, particularly under the glass, so the sauna should be dried out by heating it after use. Bitumen shingles are included and should be installed promptly once the barrel is built.
Delivery
Delivery is by lorry or semi-trailer to the curb. Access to the unloading area must be clear, and the longest components are approximately 2400 mm (94.5 inches) — so walk the route before you order: gate widths, steps, slopes, overhanging branches.
Inside delivery and assembly can usually be arranged as a separate service. Ask us before ordering and we will quote it.
Warranty
Five years, parts only, against defects in materials and workmanship under normal residential use, from the date the original purchaser receives the product. Claims are administered by Finnish Sauna Builders with the manufacturer.
The warranty does not cover normal wear and tear, weather effects, routine maintenance such as tightening the barrel bands or staining the exterior, misuse or negligence. Service and labour costs are not covered.
Check your delivery against the parts list as soon as it arrives and report anything missing or damaged to us straight away.
Frequently asked questions
How is the Vassa different from the Turku?
Both are six-person models with identical exterior dimensions. The Vassa has no terrace, so its heated interior is 86.61 inches. The Turku includes a front terrace, which reduces its heated interior to 74.80 inches. Choose the Vassa for sauna room, the Turku for a covered place to cool off.
Does it come with the heater?
Yes. An 8kW Harvia Spirit electric sauna heater is included in the package, along with the barrel cradles, pre-cut staves and wall panels, glass door, two-tier benches, duckboard flooring, fasteners, metal bands and bitumen shingles.
Do I need an electrician?
Yes, and it is not optional. The heater is hardwired, not plugged in. The manufacturer publishes 240V single phase, 60Hz, 33 amps and 8-gauge copper, and specifies that installation is carried out by a licensed electrician to local code. Send us a photo of your panel before you order and we will tell you what is involved.
Can I assemble it myself?
It is sold as a pre-cut DIY kit with no field cutting. The manufacturer specifies a minimum of two people and basic manual skills, and all screw fittings must be pre-drilled. The size and weight make a larger team easier. Electrical installation is separate and must be done by a qualified electrician.
How long does it take to arrive?
Roughly four to eight weeks. It is built after your order is confirmed rather than held in stock. We publish the range rather than the best case. If you are working to a date, call 866-427-8202 before ordering and we will confirm the current build time.
Can I return it?
No. Because it is built specifically to order, the manufacturer's policy makes it non-returnable. There is a 24-hour cancellation window from order placement; after that a 35% restocking fee applies and return shipping is deducted from any refund. This is exactly why we would rather spend twenty minutes on the phone with you first.
What foundation do I need?
A flat, load-bearing base — a slab of roughly 1880 × 1880 mm (about 6 ft 2 in square), or strip foundations at 940 mm spacing. Soil and grass will not do. Anchoring against wind is the owner's responsibility and the manufacturer does not accept liability for damage caused by inadequate anchoring.
Does the exterior need staining?
The exterior arrives untreated and the manufacturer recommends painting or staining it to protect the wood and extend its life. That is the owner's job. The interior must never be treated with paint or finish of any kind. Four exterior finishes are offered at order: Natural, Walnut, Teak and Larch.
