EOS Gracil Freestanding Electric Sauna Heater
The EOS Gracil combines refined European styling, dependable electric heat and an exceptionally shallow footprint for modern traditional sauna rooms. Its clean geometric form, flat rear profile and recessed terminal box make it especially well suited for glass-front cabins and installations where space is limited.
Choose from 6 kW, 7.5 kW or 9 kW outputs, black or anthracite finishes, and electrical configurations for compatible 240V residential or 208V three-phase commercial sauna systems.
Full Sauna Performance in a Remarkably Slim Profile
At only approximately 9.8 inches deep, the floor-standing EOS Gracil offers a space-conscious alternative to bulkier electric sauna heaters without sacrificing a full-size stone compartment. Its approximately 44-pound stone capacity supports smooth, even heat and traditional steam bursts when water is properly applied to the heated sauna stones.
The steel outer shell is available in anthracite with a pearl-effect finish or a refined matte black. A brushed stainless steel top cover adds durability and creates a finished architectural appearance for upscale residential sauna rooms.
Slim 9.8-Inch Depth
The shallow, floor-standing body helps preserve usable cabin space and supports installations near glass walls or other carefully planned sauna features.
44-Pound Stone Capacity
A full-size stone compartment provides traditional sauna heat performance despite the heater's unusually slim construction.
Made in Germany
The Gracil is manufactured by EOS Saunatechnik with durable steel and stainless steel components for long-term residential sauna use.
Select the Right EOS Gracil for Your Sauna
Select the finish, heating output and electrical configuration that match your sauna cabin and installation plan.
| Product Option | Available Selections |
|---|---|
| Finish | Black or Anthracite |
| Heater Output | 6 kW, 7.5 kW or 9 kW |
| Voltage / Phase | 240V / 2PH or 208V / 3PH Commercial |
Important: Heater output must be matched to sauna cabin construction, usable interior volume, glass area, insulation, ventilation and electrical service. Have the final selection confirmed by your sauna designer, equipment supplier and licensed electrician before ordering.
Choose 6 kW, 7.5 kW or 9 kW
EOS provides three Gracil output levels for private sauna cabins of different sizes. The room ranges below are manufacturer guidance and assume a properly constructed sauna with the minimum required ceiling height and ventilation.
| Heater Output | Recommended Sauna Room Volume | Typical Use |
|---|---|---|
| 6 kW | Approximately 213 to 300 cubic feet | Smaller private traditional sauna cabins |
| 7.5 kW | Approximately 280 to 420 cubic feet | Medium private traditional sauna cabins |
| 9 kW | Approximately 313 to 494 cubic feet | Larger private traditional sauna cabins |
Cabins with substantial glass, tile, stone or other non-insulated surfaces may require additional sizing consideration. Do not choose solely from exterior cabin dimensions.
Complete the EOS Gracil Sauna System
The EOS Gracil is an externally controlled electric sauna heater. It does not include an onboard sauna controller and cannot operate as a complete system by itself.
Required: Compatible EOS Control
Choose a compatible EOS control interface for temperature adjustment, operating time and supported sauna functions.
Required: Compatible EOS Power Box
A compatible EOS Power Box provides the high-voltage switching and electrical interface between the selected control and sauna heater.
Required: Sauna Stones
Approximately 44 pounds of properly sized sauna stones are required. Sauna stones are optional and are not listed as part of the standard heater package.
Professional Electrical Installation
The fixed high-voltage connection must be completed by a qualified electrician using the correct circuit protection, copper conductors and installation requirements for the selected model.
No Power Extension Box Required: According to the EOS Gracil technical data, the 6 kW, 7.5 kW and 9 kW configurations do not require an EOS Power Extension Box when installed with the appropriate compatible control and Power Box.
Engineered for Modern Sauna Architecture
Flat Rear Profile
The heater's flat back and recessed connection area help create a neat installation with fewer protruding components.
Durable Metal Construction
The outer and inner shells are made from steel, while the rock store, feet and top cover incorporate stainless steel components.
Optional Safety Guard Rail
A compatible wooden safety guard rail is available separately. A suitable protective guard must be incorporated into the completed cabin installation.
Efficient Heating with Traditional Sauna Steam
The EOS Gracil was engineered to combine fast, even heat with the authentic bathing experience of a traditional Finnish sauna. Its generous stone compartment allows heat to be stored within the sauna stones rather than relying solely on direct radiant heat from the heating elements.
When water is poured over properly heated sauna stones, the stored energy creates the soft, humid steam known as löyly, producing the comfortable warmth and humidity that many sauna enthusiasts prefer.
Large Stone Capacity
Approximately 44 pounds of sauna stones help stabilize temperatures while providing consistent steam production throughout the sauna session.
Balanced Heat Distribution
The slim heater body promotes natural air circulation around the heater, encouraging even heating throughout the sauna room.
Traditional Steam
Designed specifically for water application to sauna stones, producing the classic steam experience expected from a traditional electric sauna.
Residential and Commercial Voltage Options
The EOS Gracil is available in electrical configurations to match both residential and commercial sauna installations. Always verify available electrical service before selecting a heater.
240V / 2PH
Designed for compatible residential electrical systems utilizing 240-volt service. Available in 6 kW, 7.5 kW and 9 kW models.
208V / 3PH

EOS Gracil Sauna Heater FAQs
Find answers about heater sizing, electrical configurations, required controls, sauna stones, installation and maintenance for the EOS Gracil electric sauna heater.
What makes the EOS Gracil different from other sauna heaters?
The EOS Gracil combines a slim freestanding design with a substantial sauna stone compartment. Its approximately 9.8-inch depth helps preserve usable floor space while supporting traditional dry-sauna heat and steam from water applied to properly heated stones.
Which EOS Gracil heater size do I need?
The correct output depends on the heated interior volume of the sauna, insulation, ceiling height, ventilation and the amount of glass, tile, stone or other non-insulated material in the room.
- 6 kW: approximately 213 to 300 cubic feet
- 7.5 kW: approximately 280 to 420 cubic feet
- 9 kW: approximately 313 to 494 cubic feet
These are manufacturer sizing guidelines. The final heater selection should be confirmed for the specific sauna design before ordering.
Does glass affect the sauna heater size I need?
Yes. Glass doors, glass walls, tile, masonry and other non-insulated surfaces increase heat loss and may require a larger heater than the basic room volume alone would suggest. These surfaces should be included when determining the effective heated volume of the sauna.
What is the difference between the 240V / 2PH and 208V / 3PH options?
The 240V / 2PH configuration is intended for compatible installations using 240-volt electrical service. It is commonly selected for residential sauna projects and certain light commercial applications.
The 208V / 3PH configuration is designed for facilities with 208-volt three-phase electrical service, including many commercial, hospitality, fitness and institutional sauna installations.
A licensed electrician should confirm the available voltage and phase before the heater is ordered.
Can I use a 208V heater with 240V electrical service?
No. The selected heater, Power Box, control system, circuit protection and building electrical service must have compatible voltage and phase ratings. Do not install a heater on an electrical supply that does not match its approved specifications.
Does the EOS Gracil have a built-in control?
No. The EOS Gracil is an externally controlled sauna heater and requires a compatible EOS control system and matching Power Box. The control interface and Power Box are sold separately.
Which sauna controls are compatible with the EOS Gracil?
The Gracil can be incorporated into an approved EOS sauna system using a compatible controller such as the EOS Touch 3 or EOS EmoTec D. The selected control must be paired with the correct Power Box and electrical configuration.
Is an EOS Power Box required?
Yes. A compatible EOS Power Box provides the power switching and electrical connection between the external sauna control and the Gracil heater. Select the Power Box according to the heater output, voltage, phase and overall system design.
Does the EOS Gracil require a Power Extension Box?
The standard 6 kW, 7.5 kW and 9 kW Gracil configurations do not require an EOS Power Extension Box when paired with the appropriate compatible control and Power Box. The completed electrical design should still be verified before installation.
Are sauna stones included with the EOS Gracil?
Sauna stones are not listed as part of the standard heater package and should be purchased separately. The Gracil holds approximately 44 pounds of properly sized sauna stones.
Can water be poured over the stones?
Yes. The EOS Gracil is designed for traditional dry-sauna operation, including controlled application of water to properly heated sauna stones. Use clean water and follow the instructions in the official operation manual. Do not pour excessive amounts of water over the heater.
How much space does the EOS Gracil require?
The heater measures approximately 15.7 inches wide, 9.8 inches deep and 31.9 inches high. Required clearances from walls, benches, guards and other surfaces must be maintained according to the official installation manual.
Does the heater require a safety guard rail?
A suitable heater guard should be incorporated into the sauna design to help prevent accidental contact with hot surfaces. The guard must be positioned so it does not interfere with required clearances, ventilation or safe heater operation.
Can the EOS Gracil be installed against a glass wall?
Its slim body and flat rear profile make the Gracil well suited to modern cabins with glass features. However, installation near glass must still comply with all manufacturer clearances, ventilation requirements and applicable building and electrical codes.
Can the EOS Gracil be installed outdoors?
The heater is intended for installation inside a properly constructed sauna room. It should not be exposed directly to rain, snow, standing water or outdoor weather. An outdoor sauna structure must provide the protected interior environment required by the heater and control-system documentation.
Can I install the heater myself?
The physical sauna layout should follow the official EOS installation instructions, and all fixed electrical wiring must be completed by a qualified electrician. The installer must verify the heater output, voltage, phase, circuit protection, conductor sizing, control system, clearances and ventilation.
What type of ventilation does the sauna need?
The sauna requires correctly positioned fresh-air intake and exhaust ventilation to support heater performance, temperature distribution and occupant comfort. Ventilation openings should be planned according to the sauna-room design and the EOS installation manual.
How should the sauna stones be installed?
Rinse dust from the stones before loading them. Place the stones loosely around the heating elements so air can circulate through the stone compartment. Do not wedge stones tightly against the elements or block airflow through the heater.
How often should the sauna stones be inspected?
Inspect the stones periodically for cracking, crumbling and settling. Remove stone debris, replace damaged stones and restack the remaining stones loosely to preserve airflow. Inspection frequency may need to increase in frequently used or commercial saunas.
Can smartphone control be added?
Remote connectivity may be available when the heater is paired with an eligible EOS control system and the compatible EOS App Module. Approved remote-start safety equipment may also be required.
What is included with the EOS Gracil heater?
The package includes the selected EOS Gracil electric sauna heater and manufacturer documentation. The external sauna control, Power Box, sauna stones, electrical materials, safety guard and optional connectivity accessories are sold separately unless specifically stated otherwise.
What warranty does the EOS Gracil include?
The EOS Gracil includes a two-year manufacturer warranty, subject to the manufacturer's terms, approved installation, proper electrical configuration, intended use and required maintenance.
