Infrared sauna rooms are now specified as amenity assets rather than discretionary purchases. In hotels, guesthouses, wellness clubs and spa facilities, a cabin is evaluated the way other capital equipment is evaluated: output, materials, control system, documentation and serviceability. OCEAN FUTURE is a manufacturer of sauna rooms, hot tubs, swim spas and cold plunges that operates a 50,000 m² facility with more than 200 employees and a nine-engineer R&D team, produces roughly 5,000 sets per year, and exports about 85% of its output to markets including the United States, Australia, the EU and Germany.

Its OFS06 infrared range is the subject of this review. The range includes OFS06A-5 and the OFS06B models OFS06B-1, OFS06B-2, OFS06B-3-1, OFS06B-3-2 and OFS06B-4. On paper they look close to interchangeable, and in most respects they are: the same control system, the same heating technology family, the same wood species, the same glazing, lighting and audio package. What changes is how much heat the cabin is specified to produce.

This comparison works from published specification data only. It sets out what the models share, where they actually diverge, how the differences map to the venue types the range is designed for, and where the infrared platform stops and a different product family begins.

Why the OFS06 Infrared Range Is Hard to Compare on Paper

Feature parity is the core problem. Across OFS06A-5 and the OFS06B models, the published feature set is effectively identical: AV1 control, far infrared heating, tempered glass, painted surfaces, wood handles, colourful lighting, two speakers, FM/Bluetooth/USB connectivity, and hemlock, aspen and red cedar as the primary materials.

That parity has an operational upside. An operator specifying several rooms — a hotel amenity floor, a guesthouse leisure wing, a club wellness area — can install different OFS06 models in different rooms without the guest-facing experience changing between them. Materials, glazing, lighting, audio and controls remain consistent, which simplifies maintenance, spare parts and staff training.

The downside is that the feature list cannot be used to build a shortlist. Every model reviewed here is listed for the same four venue categories: the hotel & hospitality industry, guesthouse, wellness & commercial club, and spa facilities. Venue label does not narrow the choice either.

The variable that does narrow the choice is total power output. The OFS06 infrared specification set documents total power from 1,500W to 3,850W across the family, and the models compared here occupy the lower and middle part of that span.

The Shared Platform: What Every OFS06 Infrared Model Includes

• Control system: AV1 across the OFS06 infrared models.
• Heating: far infrared heating plates.
• Audio and connectivity: FM, Bluetooth and USB, with two speakers.
• Lighting: a lamp plus colourful lighting.
• Structure: tempered glass, a wood handle and a painted surface.
• Materials: hemlock, aspen and red cedar.
• Documented applications: hotel & hospitality industry, guesthouse, wellness & commercial club, and spa facilities.

Because the shared platform covers the attributes most buyers use to build a shortlist — wood species, glazing, lighting, audio, connectivity and control — the OFS06 range behaves like a power ladder rather than a feature ladder. Two buyers can order different models and receive cabins that are functionally equivalent in almost every visible respect, but not in output.

That has a practical consequence for procurement. Specifications written around features will not discriminate between these models, and neither will design intent. Only the electrical and thermal specification will.

Where the Models Actually Differ

Three observations follow from that table.

OFS06A-5 is the highest-output model in the compared set at 3,000W, followed by OFS06B-3-2 at 2,300W. Above both, the wider OFS06 infrared range is documented up to 3,850W where an installation needs additional headroom.

OFS06B-2 and OFS06B-3-1 carry the same documented 1,850W rating. Total power alone does not separate them, so a buyer choosing between the two should request a full specification sheet for each rather than assume they are interchangeable on the strength of a matching wattage.

OFS06B-4 is documented for materials, control system, heating type, glazing, lighting, audio and connectivity, but the specification set reviewed here does not record a total power figure for it. That single number should be obtained in writing before the model is placed in a shortlist alongside the others.

Everything else — painted surface, tempered glass, wood handle, colourful lighting, two speakers, FM/Bluetooth/USB, far infrared heating, AV1 control, and hemlock, aspen and red cedar construction — is common to all six models.

Matching Output to Hotels, Guesthouses, Spas and Clubs

The range's application data describes how these cabins are used rather than which model suits which venue. Documented project types include residential home saunas, hotel sauna rooms, guesthouse leisure facilities, private backyard saunas and club wellness projects, spanning the private residence, commercial club, wellness club, leisure facility, hotel and boutique guesthouse sectors. Typical markets cited are Australia, Canada, China, Germany, Spain, France, Mexico and the United States, with European and North American markets described as the primary applications.

The documented function is therapeutic sweating, muscle relaxation, improved blood circulation, stress relief and temperature therapy, operated in infrared heating mode with adjustable temperature control and a timer.

Because all six models list the same venue categories, model selection follows output and site conditions rather than venue labels. A workable sequence is to define the venue category, define the room's conditions and usage pattern, confirm the required output with the manufacturer, and then select the model whose documented power matches. Read that way, OFS06B-1 anchors the low end of the family's documented output at 1,500W; OFS06B-2 and OFS06B-3-1 at 1,850W and OFS06B-3-2 at 2,300W form the middle of the ladder; and OFS06A-5 at 3,000W is the highest in the compared set, with the wider range documented to 3,850W.

Installation conditions matter as much as output. The application documentation calls for heat-resistant and non-toxic materials, waterproof and moisture-proof construction, overheat protection, low EMF for infrared models, and durable thermal insulation. Conditions are described as high-temperature environments with variable climate exposure for outdoor placements. A control panel and a safety thermometer are required items, with infrared heating panels and LED lighting specified as supporting equipment.

What the Market Data Says About Infrared Demand

Two signals frame how a buyer should read the OFS06 range.

The installed base is large and the supply side is fragmented. Harvia Group, the sector's listed operator, estimates that there are some 18 million saunas worldwide and values the global sauna market at close to EUR 4 billion. Commercial research placed Harvia's own share of that market at about 5% in 2024, which points to a long tail of manufacturers rather than a concentrated field. For a hospitality buyer, fragmentation means supplier selection — not product category availability — is the harder decision.

Growth is steady rather than explosive. Technavio reports a 6.5% CAGR for the United States sauna market over 2026–2030, while Market.us reports 6.1% for the global market over 2023–2033. The two figures are directionally consistent but use different geographies and forecast periods, so they should not be averaged into a single benchmark. Neither figure should be treated as a property of any single product range.

Mid-single-digit growth supports replacement and amenity-upgrade demand alongside new construction. That is the commercial context in which a shared-platform infrared range makes sense: standardising across several rooms reduces specification variation without reducing the guest-facing specification.

Infrared Rooms vs Heater-Based Sauna Rooms: Know Where the Platform Stops

OCEAN FUTURE builds outside the infrared category as well, and the boundary is worth understanding before a shortlist is finalised.

The heater-based models in the same portfolio include OFS12-2-T, an outdoor sauna room with a 6kW Harvia stove (BC60E) and MXD2022 control; OFS07-1, an indoor room with an 8kW Harvia stove (BC80E) and a far infrared heating box, rated 8000W + 400W at 380 V / 50 Hz; OFS07-2, an indoor room combining a far infrared heating box with a 6kW Harvia stove (BC60E) at 8000W + 800W; and the OFS05 series, which uses Harvia stoves from 3.5kW to 8kW.

Two structural limits follow. First, documented total power for the heater-based models runs from 3,500W to 8,000W, above the 1,500W–3,850W documented for the OFS06 infrared family. Second, the OFS06 infrared models are specified with AV1 control and far infrared heating plates rather than a Harvia stove, and no sauna stone set is listed for them in the specification set reviewed. A buyer who needs the traditional heater experience, or a dual-mode cabin that combines infrared heating with a stove, will find it in the OFS07 and OFS05 families rather than in the OFS06 infrared range.

A third, softer boundary concerns differentiation within the range itself. Because the OFS06 infrared models share one feature platform, variation between them is limited to output and configuration detail. Buyers who want a materially different cabin — different control logic, a stove, a different exterior construction — are comparing across families, not within one.

The same series also includes outdoor configurations with a pentroof design, tempered glass, a wood handle, colourful lighting, two speakers, FM/Bluetooth/USB connectivity, far infrared heating and AV1 control. Those configurations are relevant where the installation is weather-exposed rather than located inside a building envelope.

A Verification Checklist Before Ordering

1. Total power, in writing. Confirm the documented output for the exact model, including OFS06B-4, for which the specification set reviewed here does not publish a figure. Where two models share a rating, ask what separates them.
2. Control system and heating configuration. The OFS06 infrared models use AV1 control and far infrared heating. Confirm both on the order confirmation, since other families in the portfolio use the MXD2022 control system.
3. Materials. Hemlock, aspen and red cedar are the documented wood species across the range. Confirm the species mix for the specific order.
4. Installation environment. Confirm heat-resistant and non-toxic materials, waterproof and moisture-proof construction, overheat protection, low EMF for infrared models, and durable thermal insulation.
5. Supporting equipment. A control panel and a safety thermometer are required items; infrared heating panels and LED lighting are specified alongside them.
6. Compliance documents. In Europe, EN 18164 — published in February 2026 — covers the design and construction of sauna rooms, warm-air rooms, steam rooms and soft steam rooms in public facilities, as reported by Sauna News. In the United States, UL 60335-2-53, published in June 2025, is the electric sauna heater standard. Room construction and heater compliance are separate review objects, so request model-specific documentation for both.
7. Commercial terms. Company-reported terms for the sauna room line include a one-set minimum order quantity and a 30–40 day lead time. Confirm both against the specific model and destination before committing.

What to Expect Next

Compliance review is splitting into two tracks. With EN 18164 addressing room design and construction in European public facilities and UL 60335-2-53 addressing electric sauna heaters in the United States, certification is no longer a single question. Buyers will increasingly request room-level and heater-level documents separately, and manufacturers who can supply both will be easier to qualify.

Specification disclosure is becoming the differentiator inside shared platforms. When several models in a range carry identical materials, glazing, lighting and controls, the only way for a buyer to choose is model-level data: output, configuration, and the conditions each model is intended for. Ranges that publish that data clearly will be easier to shortlist than ranges that describe a family generically.

For the OFS06 infrared range specifically, the deciding variables are total power between 1,500W and 3,850W, configuration detail, and how the cabin is to be used. Everything else is the platform.

Frequently Asked Questions

What is the difference between OFS06A-5 and the OFS06B models?

The difference is primarily total power output rather than features. OFS06A-5 is documented at 3,000W, while the OFS06B models range from 1,500W (OFS06B-1) and 1,850W (OFS06B-2 and OFS06B-3-1) to 2,300W (OFS06B-3-2). All of them use the same AV1 control system, far infrared heating, tempered glass, a painted surface, a wood handle, colourful lighting, two speakers, FM/Bluetooth/USB connectivity, and hemlock, aspen and red cedar construction.

How much total power does each OFS06 infrared model provide?

The documented figures are 3,000W for OFS06A-5, 2,300W for OFS06B-3-2, 1,850W for both OFS06B-2 and OFS06B-3-1, and 1,500W for OFS06B-1. No total power figure is recorded for OFS06B-4 in the specification set reviewed here. Across the wider OFS06 infrared family, documented total power runs from 1,500W to 3,850W.

What materials and features are common to all OFS06 infrared models?

Every model in the compared set is built from hemlock, aspen and red cedar with a painted surface, tempered glass and a wood handle. Each includes a lamp with colourful lighting, two speakers, FM/Bluetooth/USB connectivity, far infrared heating plates and an AV1 control system.

Which venues are these infrared sauna rooms intended for?

The manufacturer documents four intended venue categories for the OFS06 infrared models: the hotel & hospitality industry, guesthouse, wellness & commercial club, and spa facilities. Published application data for the range also covers residential home saunas, hotel sauna rooms, guesthouse leisure facilities, private backyard saunas and club wellness projects.

What supporting equipment and operating conditions apply to these sauna rooms?

The application documentation states that the sauna rooms require supporting equipment including a control panel and a safety thermometer, and that they must be used with both. Infrared heating panels and LED lighting are also specified. Documented conditions include high-temperature environments, heat-resistant and non-toxic materials, waterproof and moisture-proof construction, overheat protection, low EMF for infrared models, and durable thermal insulation. Infrared operation uses adjustable temperature control and a timer.

How does an OFS06 infrared sauna room differ from a traditional Finnish sauna room in the same portfolio?

OCEAN FUTURE also builds heater-based sauna rooms, including OFS12-2-T with a 6kW Harvia stove (BC60E), OFS07-1 with an 8kW Harvia stove (BC80E) and a far infrared heating box, OFS07-2 combining a far infrared heating box with a 6kW Harvia stove, and the OFS05 series with Harvia stoves from 3.5kW to 8kW. Those models use the MXD2022 control system and are documented at 3,500W to 8,000W total power, compared with 1,500W to 3,850W for the OFS06 infrared family. The published specifications for the OFS06 infrared models list far infrared heating and AV1 control rather than a Harvia stove.

What standards should buyers check before ordering an infrared sauna room?

For public-facility installations in Europe, EN 18164, published in February 2026, covers the design and construction of sauna rooms, warm-air rooms, steam rooms and soft steam rooms, as reported by Sauna News. In the United States, UL 60335-2-53, published in June 2025, is the electric sauna heater standard. Room construction and heater compliance are separate objects, so model-specific documentation should be requested for each.
