SaunaBox® Forge 1-Person: Traditional Finnish Sauna


Description

The SaunaBox® Forge is a precision-engineered traditional Finnish sauna built for those who demand an authentic, high-heat experience at home. Powered by a commercial-grade 3.5kW Harvia® Vega Compact heater - the same unit found in professional spa installations worldwide - it reaches a scorching 220°F, delivering the kind of deep, enveloping dry heat that defines the classic Finnish sauna ritual. The interior is crafted entirely from 100% Canadian Hemlock, a naturally aromatic, low-resin wood that stays cool to the touch even at peak temperatures, while the matte black aluminum exterior over a cedar frame stands up to sun, rain, and cold year-round.

Every detail of the Forge has been considered for both performance and atmosphere. The full-length black-tinted tempered glass door adds a striking architectural edge while providing privacy, and the color-selectable RGB LED ambient lighting transforms each session into a calming, intentional ritual. Whether placed on a backyard patio, poolside deck, or covered outdoor structure, the Forge is compact enough to fit most residential spaces while delivering spa-level results.

FAQ

Is the Forge a dry sauna or an infrared sauna?

The Forge is a traditional dry sauna - not infrared. The Harvia Vega Compact heater warms the air and sauna rocks to temperatures up to 220°F. You can pour water over the rocks to create a brief burst of steam (löyly), but the primary experience is authentic Finnish dry heat. Infrared saunas heat your body directly at much lower ambient temperatures. If you want the real Finnish sauna experience - intense heat, the option to add steam, and the ritual of high-temperature bathing - the Forge is the right choice.

What electrical setup does the Forge require?

The Forge requires a dedicated 240V hardwired circuit protected by a double-pole breaker (typically 20A - confirm with your local electrician). It draws 14.4A at operating load and uses 12/2 copper conductor wire. This is not a plug-in sauna - there is no cord or plug included. Installation must be performed by a licensed electrician. This is a one-time setup; once complete, the sauna operates with no ongoing electrical maintenance.

Can I use the Forge outdoors year-round?

Yes. The Forge is specifically designed for year-round outdoor use. The matte black aluminum exterior paneling over a cedar frame is weather-resistant and built to handle sun, rain, and cold. Simply place it on a stable, level, load-bearing surface such as a concrete pad, composite deck, pavers, or compacted gravel - and avoid areas prone to standing water. Do not place directly on soil or grass.

How is the Forge delivered and does it arrive assembled?

The Forge ships via LTL (less-than-truckload) freight in a single palletized plywood crate weighing approximately 571 lbs. Standard (free) delivery is curbside or garage-level drop-off - you are responsible for moving the unit to its final location. A Room of Choice upgrade delivers the sauna to your chosen room, unpacked and placed. White Glove Delivery includes full professional assembly by a trained 2-person team, so your sauna is ready to use the same day. A forklift or pallet jack with a 2-person team is required to move the crate from the delivery point.

How long does it take to heat up?

The Forge reaches a comfortable sauna temperature of 170°F in approximately 25 minutes from a cold start. It hits its maximum operating temperature of 220°F in approximately 40 minutes. The Harvia Vega Compact heater is rated for spaces between 70.5 and 175 cubic feet, making it well-matched to the Forge's interior volume.

Is the Forge HSA/FSA eligible?

Yes - the Forge is HSA/FSA eligible through SaunaBox's partnership with Truemed®. Using pre-tax HSA or FSA funds can save you an average of 30% on your purchase. Check with your HSA/FSA provider or visit the SaunaBox website for details on how to apply your benefits.
