Description
Scandia Electric Ultra Sauna Heater — Large (12.0–18.0KW): Serious Output for Large Custom and Commercial Saunas
At 400–800 cubic feet, most electric heaters on the market stop performing reliably. They struggle to reach temperature, cycle constantly under load, and wear out faster than they should. The Scandia Electric Ultra Large is built specifically for this range — 12.0–18.0 KW on a 240V circuit, the same 321 stainless steel internal construction as Scandia's commercial gas heaters, and enough output to heat a large custom room or commercial installation properly.
This is the heater for large custom home saunas, commercial facilities adding sauna as an amenity, and gyms or studios with dedicated recovery rooms.
SOCIAL PROOF
Scandia Manufacturing has been building sauna heaters, kits, and accessories in the USA since 1964. The same manufacturing standards that supply luxury hotel spas, university athletic facilities, and high-end health clubs across North America go into every unit shipped from their American facility.
WHY RECOVATHLETE CARRIES THIS
Large electric heater installations come with more complexity than a standard home build — 240V circuit requirements, correct placement for even heat distribution, heater guard requirements for commercial spaces. We're an authorized Scandia dealer who helps buyers get these details right before installation day.
For commercial installations, we can discuss load requirements, heater guard options, and pairing this with the right accessories for a facility-ready setup. Call 866-861-6317.
BEST FOR:
- Large custom home saunas 400–800 cubic feet
- Commercial sauna installations in gyms, studios, and wellness spaces
- High-ceiling rooms where smaller heaters can't maintain temperature
- Buyers who need electric output comparable to gas — without a gas line
- Facilities adding sauna as a premium recovery or wellness amenity
NOT IDEAL FOR:
- Home saunas under 300 cubic feet — the Medium is more efficient and less expensive
- Rooms where 240V wiring is not feasible
- Infrared saunas — this is a traditional rock heater for dry and wet sauna use
Who Buys This
- Commercial fitness facilities outfitting a large sauna as a member recovery amenity
- Custom home builders specifying a commercial-grade heater for a large dedicated sauna room
- Wellness centers and medspas adding a large sauna suite to their treatment offerings
- Operators upgrading from an undersized heater in a large room that never gets hot enough
What You're Actually Getting
- 12.0–18.0 KW output — built for 400–800 cubic foot rooms, not a stretched Medium
- 321 stainless steel internals — same specification as Scandia's commercial gas heaters
- 240V operation — higher voltage for efficient power delivery at this output level
- Compatible with sauna stones for traditional löyly steam — full steam capacity for large groups
- Built-in timer and mechanical overheat thermostat — no digital components to fail in high-use commercial environments
- Made in the USA by Scandia — same commercial-grade construction used in resort and university installations
Specs, Translated Into What They Mean
| Specification | What It Means for You |
|---|---|
| 12.0–18.0 KW | The range that handles 400–800 cubic feet reliably. Adjustable within this range to match your exact room. |
| 240V circuit | Higher voltage than standard 120V — requires a dedicated 240V circuit. Your electrician handles this; it's standard for large appliances. |
| 321 stainless internals | Commercial-grade alloy. Handles sustained high-output operation without corroding or degrading over years of use. |
| Mechanical thermostat | No electronics to replace in a commercial environment. Controls are robust for long-term high-frequency use. |

ON THE INVESTMENT
For commercial use, the investment calculus is simple: a heater that under-performs in a large room means members don't use it, which means the amenity doesn't generate retention value. The Large is sized correctly for large rooms and built to run daily without degrading. It's the correct unit for the application — a smaller heater is not a cost savings, it's a mismatch.

Scandia Electric Ultra Sauna Heater — Large (12.0–18.0KW): Serious Output for Large Custom and Commercial Saunas
At 400–800 cubic feet, most electric heaters on the market stop performing reliably. They struggle to reach temperature, cycle constantly under load, and wear out faster than they should. The Scandia Electric Ultra Large is built specifically for this range — 12.0–18.0 KW on a 240V circuit, the same 321 stainless steel internal construction as Scandia's commercial gas heaters, and enough output to heat a large custom room or commercial installation properly.
This is the heater for large custom home saunas, commercial facilities adding sauna as an amenity, and gyms or studios with dedicated recovery rooms.
SOCIAL PROOF
Scandia Manufacturing has been building sauna heaters, kits, and accessories in the USA since 1964. The same manufacturing standards that supply luxury hotel spas, university athletic facilities, and high-end health clubs across North America go into every unit shipped from their American facility.
WHY RECOVATHLETE CARRIES THIS
Large electric heater installations come with more complexity than a standard home build — 240V circuit requirements, correct placement for even heat distribution, heater guard requirements for commercial spaces. We're an authorized Scandia dealer who helps buyers get these details right before installation day.
For commercial installations, we can discuss load requirements, heater guard options, and pairing this with the right accessories for a facility-ready setup. Call 866-861-6317.
BEST FOR:
- Large custom home saunas 400–800 cubic feet
- Commercial sauna installations in gyms, studios, and wellness spaces
- High-ceiling rooms where smaller heaters can't maintain temperature
- Buyers who need electric output comparable to gas — without a gas line
- Facilities adding sauna as a premium recovery or wellness amenity
NOT IDEAL FOR:
- Home saunas under 300 cubic feet — the Medium is more efficient and less expensive
- Rooms where 240V wiring is not feasible
- Infrared saunas — this is a traditional rock heater for dry and wet sauna use
Who Buys This
- Commercial fitness facilities outfitting a large sauna as a member recovery amenity
- Custom home builders specifying a commercial-grade heater for a large dedicated sauna room
- Wellness centers and medspas adding a large sauna suite to their treatment offerings
- Operators upgrading from an undersized heater in a large room that never gets hot enough
What You're Actually Getting
- 12.0–18.0 KW output — built for 400–800 cubic foot rooms, not a stretched Medium
- 321 stainless steel internals — same specification as Scandia's commercial gas heaters
- 240V operation — higher voltage for efficient power delivery at this output level
- Compatible with sauna stones for traditional löyly steam — full steam capacity for large groups
- Built-in timer and mechanical overheat thermostat — no digital components to fail in high-use commercial environments
- Made in the USA by Scandia — same commercial-grade construction used in resort and university installations
Specs, Translated Into What They Mean
| Specification | What It Means for You |
|---|---|
| 12.0–18.0 KW | The range that handles 400–800 cubic feet reliably. Adjustable within this range to match your exact room. |
| 240V circuit | Higher voltage than standard 120V — requires a dedicated 240V circuit. Your electrician handles this; it's standard for large appliances. |
| 321 stainless internals | Commercial-grade alloy. Handles sustained high-output operation without corroding or degrading over years of use. |
| Mechanical thermostat | No electronics to replace in a commercial environment. Controls are robust for long-term high-frequency use. |

ON THE INVESTMENT
For commercial use, the investment calculus is simple: a heater that under-performs in a large room means members don't use it, which means the amenity doesn't generate retention value. The Large is sized correctly for large rooms and built to run daily without degrading. It's the correct unit for the application — a smaller heater is not a cost savings, it's a mismatch.
