OFS06B-1 infrared sauna room: 1500W total power, far infrared heating plate and box, AV1 control system, painted surface and tempered glass.

An infrared sauna room is decided by three parameters before anything else is discussed: total power, the wood and surface build of the cabin, and the control system that runs the heating and the feature layer. Lighting, glazing, handles and audio all hang off those three decisions rather than replacing them.

This technical guide works through that specification process using seven published OCEAN FUTURE models as a reference set: OFS06A-5, OFS06B-1, OFS06B-2, OFS06B-3-1, OFS06B-3-2, OFS06B-4, and OFS06B-5, which defines the top of the published power range at 3850W. The same series is published for hotel & hospitality, guesthouse, wellness & commercial club, and spa facilities applications.

The short answer, for buyers comparing model codes: in this series the feature layer is effectively constant and the total power is not. OFS06B-1 is rated at 1500W, OFS06B-2 and OFS06B-3-1 at 1850W, OFS06B-3-2 and OFS06B-4 at 2300W, OFS06A-5 at 3000W, and OFS06B-5 at 3850W — while hemlock, aspen and red cedar construction, a painted surface, tempered glass, wood handles, colorful lighting, two speakers, FM/Bluetooth/USB connectivity and the AV1 control system are documented across the whole set.

Why the Model Number Alone Does Not Answer a Specification Question

Published parameter data for the six reference models describes a shared build. Each unit is constructed from hemlock, aspen and red cedar, finished with a painted surface, and fitted with tempered glass, a wood handle, a lamp with colorful light, two speakers, FM/Bluetooth/USB connectivity, far infrared heating and an AV1 control system. What separates the model codes in the published data is the total power rating.

That single fact changes how a comparison should be read. A buyer who treats OFS06B-1 through OFS06B-4 as a feature ladder will either oversize the electrical works or pay for differences the published data does not describe. A buyer who reads the same list as a power ladder can match a project to a heat-output tier first, then specify wood, finish and controls separately on the same order line.

Two further specification risks appear in the same data set:

• Scope gaps. Published product data states that the sauna room must be used with a control panel and a safety thermometer, and lists supporting equipment such as sauna heater, infrared heating panels, control panel, LED lighting and safety thermometer. A quotation that omits those items cannot be compared with one that includes them.
• Environment gaps. Published application data covers indoor and outdoor installation under high temperature and variable climate — sun exposure, rain, low temperature — together with corrosion resistance, heat-resistant and non-toxic materials, waterproof and moisture-proof construction and overheat protection. Infrared models additionally carry a low EMF requirement, and outdoor models a UV-resistance requirement.

Neither risk is visible from a model code. Both are decided by the parameters behind it.

Industry Background: Where the Infrared Segment Stands in 2026

Market data published by Grand View Research puts the global sauna market at USD 954.3 million in 2025, with a projected value of USD 1,556.8 million by 2033. Within that market, the residential segment dominated with a 58.92% share in 2025. On the product side, traditional saunas held the largest share at 42.79% in 2025, while infrared saunas were the fastest-growing segment at a 7.5% CAGR — which is the segment this guide addresses.

Demand is concentrated geographically as well. The United States sauna market generated USD 250.8 million in revenue in 2024, approximately 21.8% of global revenue, according to Topture / Technavio. OCEAN FUTURE's own export pattern points in the same direction: approximately 85% of its products are exported, with the USA, Australia, the EU and Germany listed as main markets, and published application markets including Australia, Canada, China, Germany, Spain, France, Mexico and the United States.

Compliance is moving at the same pace. A new electric sauna heater safety standard, UL 60335-2-53, was published in June 2025 to align US regulations with international standards, according to Underwriters Laboratories and SaunaTimes. For specifiers, that pushes the electrical part of the conversation earlier in the project: power rating, heater configuration and control documentation are now reviewed together rather than after the cabin has been chosen.

The Three Selection Axes in Detail

Axis 1 — Total power: a published ladder from 1500W to 3850W

Total power is the parameter that changes across the reference set. The published ratings read as a ladder rather than a list:

For project planning, the practical reading of that ladder is straightforward. OFS06B-1 at 1500W sits at the bottom of the published range. OFS06B-2 and OFS06B-3-1 at 1850W, and OFS06B-3-2 and OFS06B-4 at 2300W, form the middle. OFS06A-5 at 3000W and OFS06B-5 at 3850W sit at the top.

Where two model codes share one power rating, power alone no longer decides the model. Those remaining differences are not part of the published parameter set used here, so they should be confirmed with the supplier at quotation stage rather than inferred from the model number.

Power also has an electrical consequence. Published data for OCEAN FUTURE's higher-power, heater-based sauna rooms lists rated voltages of 220V/50Hz or 380V/50Hz, while the infrared models in this guide are documented by total power. Voltage, phase and circuit protection for a specific destination market should therefore be confirmed in writing before the electrical works are priced — never transferred from another family by assumption.

Axis 2 — Heating element configuration: the far infrared plate and the box

The reference models use far infrared heating. In published parameters the element line reads "far infrared heating plate + box" for OFS06B-1, OFS06B-2, OFS06B-3-2, OFS06B-4 and OFS06A-5, and "far infrared heating plates" for OFS06B-3-1. The distinction matters at quotation stage, because "far infrared" describes the radiant spectrum rather than the physical assembly: whether a model is built with plates, a box, or a plate-and-box combination should be stated explicitly per model code instead of assumed from the series name.

Two practical habits follow. First, request the element configuration and the total power on the same line of the quotation so the heating assembly can be verified against the model code. Second, plan spare and replacement parts against the exact model code: a series description is not enough detail for sourcing a heating element or a control component.

OFS06B-3-2: mid-range 2300W infrared sauna room with far infrared heating plate and box, painted surface, tempered glass and AV1 control.

Axis 3 — Wood and surface: hemlock, aspen and red cedar under a painted finish

Wood species is not the variable that changes the model number in this set. All six reference models are published with hemlock, aspen and red cedar as construction materials, and all six are documented with a painted surface. The same data lists tempered glass and a wood handle on every one of them.

For a project, that means the wood line on the order is a finish decision rather than a model decision — the material is chosen for the visual and interior concept, while the model code continues to be set by power tier. Two checks are worth adding to the specification, both taken from OCEAN FUTURE's published application data: materials must be heat-resistant and non-toxic, and the build must be waterproof and moisture-proof wherever it is exposed. Outdoor placement adds a UV-resistance requirement, and infrared models carry a low EMF requirement.

OFS06B-4: 2300W infrared sauna room, available in hemlock, aspen or red cedar with a painted surface and wood handle.

Axis 4 — The AV1 control system and the feature layer around it

AV1 is the control system documented across the reference models. Published data describes it as the control method for these units and as an integrated system that manages FM, Bluetooth and USB functions together with the speakers. In practice, AV1 is the interface between the electrical installation, the far infrared heating assembly and the cabin features — and the part of the specification a facility or maintenance team will interact with long after installation.

The feature layer around AV1 is published identically across the six models: a lamp with colorful light, two speakers, and FM, Bluetooth and USB connectivity. Because that layer is constant, a comparison between these models does not need to weigh audio or lighting differences. The meaningful comparison points are total power, element configuration, wood and finish, and the scope list that must accompany the control system — a control panel and a safety thermometer.

Step-by-Step: Specifying an Infrared Sauna Room

1. Define the installation environment. Decide between indoor and outdoor placement first. Published application data covers indoor/outdoor installation under high temperature, variable climate (sun exposure, rain, low temperature) and corrosion-resistant conditions; outdoor placement brings a UV-resistance requirement and infrared models carry a low EMF requirement.
2. Confirm the electrical envelope. Fix the candidate model code and its total power, then have voltage, phase and circuit protection confirmed for the destination market. Do not transfer voltage figures from another product family without written confirmation.
3. Select the power tier. Choose from the published ladder: 1500W (OFS06B-1), 1850W (OFS06B-2, OFS06B-3-1), 2300W (OFS06B-3-2, OFS06B-4), 3000W (OFS06A-5) or 3850W (OFS06B-5).
4. Select the wood species. Hemlock, aspen or red cedar — available across the range, so this is a finish line rather than a model line.
5. Lock the surface and glazing package. Painted surface, tempered glass and wood handle are documented on the reference models; confirm the finish against the project's interior specification.
6. Specify the control and feature layer. AV1 control system, far infrared heating, lamp with colorful light, two speakers, and FM/Bluetooth/USB connectivity.
7. Complete the scope list. Include the control panel and safety thermometer required for operation, and obtain a parameter sheet per model code covering total power, heating element configuration, materials and control before the order is placed.

Use Cases: Matching the Reference Set to Project Types

All six reference models are published for the same four application groups: hotel & hospitality, guesthouse, wellness & commercial club, and spa facilities. Published application data also covers private residences, commercial clubs, wellness clubs, leisure facilities, boutique guesthouses, residential home saunas, private backyard saunas and club wellness projects. Because the target industries are shared, selection inside the reference set is driven by power tier and installation environment rather than by industry label.

• Hotel & hospitality, multi-unit properties. One documented control system across units keeps operator training and maintenance consistent; the power ladder allows different areas to be specified from a single product family.
• Guesthouse and boutique guesthouse. The lower tiers — 1500W (OFS06B-1) and 1850W (OFS06B-2, OFS06B-3-1) — sit at the bottom of the published power range, which matters where a property has limited electrical headroom.
• Wellness & commercial club. The 2300W models (OFS06B-3-2, OFS06B-4) and the 3000W OFS06A-5 occupy the middle and upper-middle of the range.
• Spa facilities. The highest published ratings in the family — 3000W OFS06A-5 and 3850W OFS06B-5 — sit at the top of the range.
• Residential and private installations. Published applications include residential home saunas and private backyard saunas; the same three questions apply — electrical envelope, power tier, finish.

A separate consideration applies to hot and wet environments. The published function set for these units covers therapeutic sweating, muscle relaxation, improved blood circulation, stress relief and temperature therapy, and the application data requires heat-resistant, non-toxic materials alongside waterproof and moisture-proof construction. Those requirements belong in the specification document, not in a post-installation conversation.

Comparison: What Changes and What Stays the Same

The two tables below summarise the published parameter set for the reference models — first what changes across model codes, then what is documented identically.

Read together with the power table above, the two lists give a simple buying rule: use the power table to select a model code, and use the constant-parameter table to check that a quotation describes the build completely. A quotation that lists a model code but not the heating element configuration, the wood species, the surface treatment or the companion items is incomplete in a way that is easy to miss.

OFS06B-5: the highest published rating in the infrared family at 3850W total power, with painted surface, tempered glass and AV1 control.

Frequently Asked Questions

What has to be verified before an infrared sauna room is ordered for a project?

Three things should be verified in writing. First, the electrical and safety requirements of the destination market: a new electric sauna heater safety standard, UL 60335-2-53, was published in June 2025 to align US regulations with international standards, according to Underwriters Laboratories and SaunaTimes, so the applicable documentation should be confirmed with the supplier rather than assumed. Second, the environmental requirements of the installation: OCEAN FUTURE's published application data specifies heat-resistant and non-toxic materials, waterproof and moisture-proof construction, overheat protection, and operation under high-temperature, variable-climate and corrosion-resistant conditions, with low EMF for infrared models and UV resistance for outdoor models. Third, the market itself — published application markets include Australia, Canada, China, Germany, Spain, France, Mexico and the United States, and approximately 85% of OCEAN FUTURE's products are exported, with the USA, Australia, the EU and Germany listed as main markets.

What actually separates OFS06B-1, OFS06B-2, OFS06B-3-1, OFS06B-3-2 and OFS06B-4?

In the published parameter set, the separating factor is total power: OFS06B-1 is rated 1500W, OFS06B-2 and OFS06B-3-1 are rated 1850W, and OFS06B-3-2 and OFS06B-4 are rated 2300W. The rest of the documented build is shared: hemlock, aspen and red cedar construction, a painted surface, tempered glass, a wood handle, a lamp with colorful light, two speakers, FM/Bluetooth/USB connectivity, far infrared heating and the AV1 control system. The family continues above that tier with OFS06A-5 at 3000W and OFS06B-5 at 3850W. Where two model codes share one power rating, the remaining differences are not captured by power alone and should be confirmed with the supplier.

What drives the cost of an infrared sauna room?

Cost follows specification, not the model code alone. The variables that appear in a quotation are the total power tier, the wood species selected from hemlock, aspen and red cedar, the surface and finish package (the reference models are delivered with a painted surface), the glazing and hardware (tempered glass and wood handle), the control and feature layer (AV1 control, lamp with colorful light, two speakers, FM/Bluetooth/USB), the order quantity, and any customization requested beyond the published parameter set. The practical approach is to fix the model code, wood species, finish and scope list first, then request quotations on that fixed basis — including the control panel and safety thermometer that published data lists as required companion items.

How can a buyer check the build before committing to a full order?

Start by fixing the specification so that anything delivered can be measured against it: model code, total power, heating element configuration, wood species, surface, control system and scope list. Then request the model parameter sheet, the product brochure and sample arrangements through the contact channels listed at the end of this guide. Because the feature layer — lamp with colorful light, two speakers, FM/Bluetooth/USB and the AV1 control system — is documented identically across the reference models, the useful checks are the cabin finish, the hardware, the control panel layout, and the heating element configuration stated against the exact model code.

What determines lead time on an infrared sauna room order?

Lead time is not a single fixed figure, because it depends on the model code and power tier, the wood species and finish, the control and feature layer, the order quantity, and the destination market together with shipping arrangements. Published data for these models documents product parameters, not a delivery schedule, so the schedule should be confirmed in writing at quotation stage, model by model.

Conclusion: Specify Power, Wood and Control — Then Verify Everything Else

For the reference models in this guide, the specification order is clear. Total power sets the model code, on a published ladder running from 1500W on OFS06B-1 through 1850W on OFS06B-2 and OFS06B-3-1, 2300W on OFS06B-3-2 and OFS06B-4, 3000W on OFS06A-5 and 3850W on OFS06B-5. Wood and surface form the second decision, with hemlock, aspen and red cedar available as materials and a painted surface, tempered glass and a wood handle documented across the set. The AV1 control system forms the third, carrying the lamp with colorful light, two speakers and FM/Bluetooth/USB connectivity, and requiring a control panel and safety thermometer as companion items.

Everything beyond that — market context, compliance position and delivery schedule — should be verified in writing rather than assumed from a series name. That is what separates a quotation that can be compared from one that cannot.
