An infrared sauna room shortlist is, in practice, a power-and-fit decision. Room volume, session turnover, electrical supply and the compliance file a venue can present to an inspector determine which model band belongs in the specification — not the marketing description of the cabin. Six models in the OCEAN FUTURE infrared range sit across five power bands, from 1500W to 3850W, and share one control system, one heating principle and one material set. This reference maps each model to the hospitality and wellness venue it suits, and states where the shortlist stops.

OCEAN FUTURE is a sauna room, hot tub, swim spa and cold plunge manufacturer operated by FOSHAN GAOMING MUHE JINGCHENG SANITARY WARE CO., LTD. in Foshan, Guangdong, China. The company operates a 50,000 m² facility with 200+ employees and reports annual output of approximately 5,000 sets, with roughly 85% of products exported to markets including the USA, Australia, the EU and Germany. Its infrared sauna models OFS06A-5, OFS06B-1, OFS06B-2, OFS06B-3-1, OFS06B-3-2 and OFS06B-4 are the subject of this shortlist.

Why Power Band Is the First Procurement Filter

Infrared cabins are specified around heat output per room, not around a single universal size. A venue that installs a 1500W model in a room sized for a 3000W or 3850W unit will run longer cycles to reach the same working temperature; a venue that installs a high-output unit in a small single-occupancy room carries electrical load it cannot recover. That is the commercial problem behind the model numbering: the six OFS06 units exist because hospitality buyers do not all need the same thermal envelope.

The opportunity sits on the other side of the same decision. Because all six models share AV1 control, far infrared heating plates, tempered glass, a wood handle, colorful lighting, two speakers and FM/Bluetooth/USB connectivity, a buyer can standardise the guest experience across a property while varying only the power band and the enclosure. Operators running several room classes — a hotel with standard rooms, suites and a spa floor — can keep one control logic and one service routine across the property.

The Six-Model Shortlist at a Glance

All six are infrared sauna rooms. None of them is listed as an outdoor model; the outdoor option in the wider range is OFS06B-5, which carries a pentroof design. Buyers specifying a terrace or poolside installation should look at that model rather than at this shortlist.

Band by Band: What 1500W to 3850W Actually Buys

1500W — OFS06B-1

The lowest-output unit in the group, and the one most often proposed for guesthouses and single-room hotel installations. It uses a far infrared heating plate and box, carries the AV1 control system, and includes a painted surface, tempered glass, wood handle, colorful lighting, two speakers and FM/Bluetooth/USB. Because it sits at the bottom of the range, it fits venues where the sauna is an amenity rather than a revenue centre: a boutique guesthouse with a handful of rooms, or a hotel suite where sessions are booked individually.

1850W — OFS06B-2 and OFS06B-3-1

Two models occupy this band, and the distinction is deliberate rather than a numbering accident. On the published specification both are 1850W, both use AV1, both use far infrared heating plates, and both list tempered glass, a wood handle, colorful lighting, two speakers, FM/Bluetooth/USB and a painted surface. A buyer comparing only the feature list will find them indistinguishable. The practical consequence is that this band has to be resolved on enclosure configuration, internal layout and dimensional fit — details a buyer must request from the supplier rather than infer from the shortlist.

2300W — OFS06B-3-2

The mid-band unit, positioned for hotels, wellness clubs and spa facilities where sessions run through the day. It is built from hemlock, aspen and red cedar, uses far infrared heating plates and AV1 control, and includes tempered glass, a wood handle, colorful lighting, two speakers and FM/Bluetooth/USB. For a spa floor scheduling back-to-back appointments, this is the smallest band in the shortlist that steps clearly away from amenity-grade output.

3000W — OFS06A-5

The A-series entry in the shortlist, and the second-highest output. It pairs a far infrared heating plate and box with AV1 control and includes a painted surface, wood handle, colorful lighting, two speakers, tempered glass and FM/Bluetooth/USB. Its position in the range makes it the natural step-up model for a hotel or commercial club that wants a larger cabin without moving to the top of the power range.

3850W — OFS06B-4

The highest-output model in this shortlist, aimed at the largest rooms and the heaviest duty cycles: spa facilities and commercial wellness clubs. It carries AV1 control, far infrared heating plates, a painted surface, tempered glass, wood handles, a lamp with colorful lighting, two speakers and FM/Bluetooth/USB. At this end of the range, the electrical supply and the room enclosure become the binding constraints, not the cabin features.

Shared Engineering Across All Six Models

The six models are easier to evaluate as one platform with five power settings than as six unrelated products. The shared elements are:

• AV1 control system — the same controller across every model in the shortlist, which simplifies operator training and spare-part planning in a multi-room property.
• Far infrared heating plates — the heat source in all six. OFS06B-1 and OFS06A-5 are described as using a far infrared heating plate and box; the other four are described as using far infrared heating plates.
• Tempered glass and wood handle — specified on every model, with a painted surface stated on all except OFS06B-3-2 in the available description.
• Colorful lighting and two speakers — present across the range, alongside FM radio, Bluetooth and USB connectivity.
• Hemlock, aspen and red cedar — the stated material set for the whole series.

What the platform does not include is equally relevant. There is no Wi-Fi function listed for these six models — connectivity is FM, Bluetooth and USB. There is no sauna stove, no sauna stone set and no steam generator in the specification. Buyers who need those elements are specifying a different product family, not a higher trim of this one.

Hemlock, Aspen or Red Cedar: What the Material Choice Means

All six models are offered in hemlock, aspen and red cedar, and the three woods carry different commercial and technical positions. Red cedar is the premium option: it is rot-resistant and aromatic, and it is priced accordingly. Hemlock sits in a budget-premium position — lower scent, neutral appearance and stable behaviour. Aspen is the budget option and a traditional Finnish sauna choice, valued for heat resistance.

For a hospitality buyer the decision usually follows the room class rather than the engineering. A spa reception-adjacent cabin that guests photograph and describe is a different specification from a back-of-house amenity cabin in a guesthouse. The material question is also a maintenance question: a venue with a structured cleaning and inspection routine can protect a premium wood far more effectively than a venue where the cabin is cleaned opportunistically.

Matching Models to Venue Type

Hotel and hospitality

Hotels typically need a spread rather than a single model: OFS06B-1 for suite-level amenities and low-turnover rooms, OFS06B-2 or OFS06B-3-1 for standard wellness rooms, and OFS06A-5 where the cabin serves a larger guest-facing space. Standardising on AV1 across the property keeps operation consistent.

Guesthouse

Guesthouses usually run short, booked sessions with long idle periods between them. The 1500W OFS06B-1 and the 1850W band fit this pattern, and the lower output reduces the electrical demand a smaller property has to support.

Wellness and commercial club

Clubs with membership traffic need cabins that recover quickly between users. The 2300W OFS06B-3-2 and the 3000W OFS06A-5 sit in the range where session turnover, rather than room size alone, drives the choice.

Spa facilities

Spa floors combine the largest rooms with the tightest scheduling. OFS06B-4 at 3850W is the model at the top of this shortlist, with OFS06B-3-2 as the mid-band option for smaller treatment rooms. The company also lists a broader applicability across private residences, commercial clubs, wellness clubs, leisure facilities, hotels and boutique guesthouses for its sauna range.

Market Context for 2026 Buyers

Published estimates for the sauna market differ enough that buyers should treat any single headline figure as directional. Technavio reports the US sauna market at USD 437.4 million in 2025, growing at a CAGR of 6.5% over 2026–2030. Market.us reports the global market at USD 860.3 million in 2023, reaching USD 1,555.3 million by 2033 at a CAGR of 6.1%. Harvia, a listed sauna company, estimates the global sauna market at close to EUR 4 billion in value with roughly 18 million saunas installed worldwide — a broader definition that includes the installed base and related services rather than equipment alone.

The three figures are not interchangeable. They use different geographies, base years and market definitions, and no average of them would be defensible. What they support collectively is a modest, consistent growth signal — mid-single-digit annual expansion — rather than a specific market size a buyer should quote in a business case.

The more decision-relevant trend for hospitality buyers is regulatory rather than commercial. The publication of EN 18164 for public-facility sauna rooms in Europe and UL 60335-2-53 for electric sauna heaters in the US raises the documentation standard a venue is expected to hold. Separately, a Europe-focused requirement figure of 36% for FSC-certified wood in commercial sauna installations has been reported in company-published market material; buyers should treat it as a signal to ask the certification question early rather than as a validated market statistic.

Compared with Traditional Finnish Sauna Rooms

The honest comparison is not that infrared replaces traditional sauna — it is that the two do different jobs, and the six OFS06 models sit firmly on one side of the line.

The boundary to state plainly: none of the six OFS06 models delivers a steam or löyly experience. A venue whose brand promise is a Finnish sauna ritual, or whose guests expect to pour water on stones, will not satisfy that expectation with this shortlist, regardless of which power band it selects. Those buyers need the traditional line — the OFS05 models use Harvia stoves rated at 8kW (BC80E) with a total power of 8000W and a 380V/50Hz supply, and ship with a wooden bucket, spoon, sandglass, hygrothermograph and one set of sauna stones.

A second limitation concerns configuration. The published specification for the six models establishes power, control, heating type, materials and features, but does not establish cabin dimensions, internal seating layout or the specific configuration difference between OFS06B-2 and OFS06B-3-1. Those have to be obtained from the supplier before a purchase order, and a shortlist alone should not be treated as a dimensional specification.

What to Put in the Procurement File

• Power and electrical supply — confirm the model's total power against the venue's available circuit and the room's intended use pattern.
• Model-specific certification documents — OCEAN FUTURE states ETL, CE and FSC certification and export experience in the EU, US and Australia. A secondary industry article references CE-EMC and EMC compliance tested by Guangzhou STU Hengchuang Testing Service Co., Ltd., covering EN IEC 55014 and EN 61000 series standards. Buyers should still request the certificate covering the exact model and market, since certification claims are typically issued per product and per jurisdiction.
• Room construction standard — for European public-facility projects, check the specification against EN 18164 scope; for US projects, separate the heater standard question (UL 60335-2-53) from the room construction question.
• Wood grade and finish — state the species (hemlock, aspen or red cedar), the finish and the maintenance interval expected of the operator.
• Spares and control continuity — where several cabins are purchased, confirm that all units carry the same AV1 control system so that one service routine covers the property.
• Configured dimensions and layout — obtain cabin drawings, especially where OFS06B-2 and OFS06B-3-1 are being compared at the same 1850W rating.

Future Outlook

Two forces are likely to shape infrared shortlists over the next few procurement cycles. The first is documentation: as public-facility standards mature in Europe and heater standards take effect in the US, the model that wins a hotel or spa tender will increasingly be the one whose certificate file is complete per model and per market, not the one with the longest feature list. The second is range architecture: buyers standardising across multi-room properties benefit from suppliers who keep control logic and materials constant while varying only power band, because that reduces training, spares and maintenance complexity. A manufacturer exporting roughly 85% of output to the USA, Australia, the EU and Germany is exposed to both forces at once, which makes the completeness of its model-level documentation a reasonable question to ask early.

Frequently Asked Questions

What is an infrared sauna room, and where do the OFS06 models fit?

An infrared sauna room is an enclosed cabin that heats occupants with far infrared heating plates rather than by heating stones in a stove. The OFS06 series is an infrared model group built on AV1 control, far infrared heating plates, tempered glass and a wood handle, with hemlock, aspen and red cedar construction and FM/Bluetooth/USB connectivity with two speakers.

What are the power ratings of the six OFS06 models?

OFS06B-1 is rated at 1500W; OFS06B-2 and OFS06B-3-1 at 1850W each; OFS06B-3-2 at 2300W; OFS06A-5 at 3000W; and OFS06B-4 at 3850W. All six use the AV1 control system and far infrared heating.

OFS06B-2 and OFS06B-3-1 are both 1850W — how should a buyer choose between them?

On the published specification the two models share the same 1850W rating, AV1 control, far infrared heating plates, tempered glass, wood handle, colorful lighting, two speakers, FM/Bluetooth/USB connectivity and painted surface. The differentiation therefore lies in enclosure configuration, dimensions and layout rather than in heating output, and those details must be requested from the supplier before selection.

Which wood is appropriate for a hotel or spa project — hemlock, aspen or red cedar?

Red cedar is the premium choice, offering rot resistance and aroma at a higher price. Hemlock is a budget-premium option with lower scent, a neutral look and stable behaviour. Aspen is the budget option and a traditional Finnish sauna wood valued for heat resistance. All three are offered across the OFS06 series, so the choice usually follows room class and maintenance capability rather than the model number.

Which venue types are these models intended for?

The stated applications are the hotel and hospitality industry, guesthouses, wellness and commercial clubs, and spa facilities. Within that set, the 1500W OFS06B-1 fits low-turnover guesthouse and suite installations, the 1850W and 2300W bands fit standard hotel and club rooms, and the 3000W and 3850W models suit larger or higher-throughput spa and commercial club spaces.

Are these traditional Finnish sauna rooms or steam sauna rooms?

Neither. All six are infrared sauna rooms using far infrared heating plates, with no sauna stove, sauna stones or steam generator in the specification. Traditional Finnish models in the same manufacturer's range, such as the OFS05 series, use Harvia stoves and ship with stones and accessories; venues requiring steam or löyly should specify that product family instead.

What should a buyer verify before ordering?

Verify the exact model's power rating against the venue's electrical supply, request the certification document that covers that model and destination market, confirm the wood species and finish, and obtain the cabin dimensions and layout drawings. For projects in Europe, review the room against the EN 18164 scope for public-facility sauna rooms; for the US, treat heater compliance (UL 60335-2-53) as a separate check from room construction.
