Infrared Sauna Room Buying Comparison: OFS06B-1 vs. OFS06B-2 vs. OFS06B-4

OCEAN FUTURE product facility panorama.

For a hotel, spa or commercial wellness buyer, the difference between two similarly named infrared sauna rooms is not just a model number. It affects electrical planning, heating layout and the visual finish that guests will remember. This article compares three OCEAN FUTURE B-series infrared rooms, with OFS06A-5 included as a reference point, using the published specification data supplied by OCEAN FUTURE.

Short answer: OFS06B-1 is the 1500 W model. OFS06B-2 is the 1850 W step-up. OFS06B-4 is the 2300 W version. OFS06A-5 is the 3000 W infrared room in the same comparison set. If your buyer brief mentions a B-series model at 1850 W, that specification corresponds to OFS06B-2, not OFS06B-1.

Why Model-Level Comparison Matters for Hotel and Spa Buyers

Many hospitality RFQs start with broad wording such as commercial sauna room or hotel spa steam sauna room. That wording is useful for identifying the category but insufficient for issuing a purchase order. Buyers need to know which heater configuration is inside the cabin, what total power has to be supplied on site, and which wood surfaces will be visible in the finished installation.

The OCEAN FUTURE model family has several prefixes, including OFS06A, OFS06B and OFS06C. Within each family there are also multiple power versions. This article deliberately focuses on the B-series trio named in the title because it is a common group for procurement shortlists. OFS06A-5 appears in the same decision because it offers a higher power rating and uses a slightly different published far infrared heating arrangement.

Industry Context for Infrared Saunas in Commercial Settings

The broader sauna market is growing. Grand View Research estimated the global sauna market at USD 954.3 million in 2025 and projected it to reach USD 1,556.8 million by 2033. Traditional saunas still held the largest product share at 42.79% in 2025, but infrared saunas were reported as the fastest-growing product segment, with a projected CAGR of 7.5%. For a wellness operator, this trend supports having an infrared room alongside more traditional heat experiences.

For commercial buyers, sustainability and wood provenance are also increasingly part of the conversation. One industry report cited by Topture estimated that European commercial developers prioritized FSC-certified sustainably sourced wood in 36% of new sauna installations in 2024. That does not mean every OCEAN FUTURE model is FSC-certified. It means buyers should ask for material documentation when timber is a tender requirement.

Published Product Facts: OFS06B-1 vs OFS06B-2 vs OFS06B-4 vs OFS06A-5

The following facts come from the OCEAN FUTURE product data provided for this comparison. All four models are listed as infrared sauna rooms, not as outdoor sauna cabins. OCEAN FUTURE, the sauna and spa brand manufactured by Foshan Gaoming Muhe Jingcheng Sanitary Ware Co., Ltd., uses these model numbers across its infrared sauna room range.

• All four models list the AV1 control system.
• All four include FM, Bluetooth and USB connectivity and two speakers.
• All four include a lamp and colorful interior light.
• All four include a wood handle and tempered glass as part of the published construction list.
• All four list a painted surface.
• All four list hemlock, aspen and red cedar as material options.
• All four list the same intended application fields: hotel and hospitality industry, guesthouse, wellness and commercial club, and spa facilities.

The main distinction between OFS06B-1, OFS06B-2 and OFS06B-4 is total power: 1500 W, 1850 W and 2300 W. The referenced OFS06A-5 is the highest-power unit in this comparison at 3000 W. There is also a published heater-layout difference. The three B-series units list far infrared heating plate plus box, while OFS06A-5 lists far infrared heating plate. OCEAN FUTURE does not supply room dimensions or heat-up time in the product data used here, so those parameters should be confirmed before final specification.

Wood Selection: Hemlock, Aspen and Red Cedar

All models reviewed here publish hemlock, aspen and red cedar as material options. For hospitality buyers, wood choice is not only aesthetic. It affects the guest experience, cleaning routine and long-term appearance under heat and humidity.

Red cedar is commonly used in sauna interiors because it is naturally aromatic and has good moisture resistance. Its warm color can make a room feel more traditional. Hemlock is another conventional sauna wood with a fine, relatively light appearance. It is often chosen when the operator wants a cleaner, more neutral finish. Aspen offers a pale and low-scent alternative. These are general wood characteristics; before selecting a wood for a large project, request actual samples from the supplier to check tone consistency across multiple units.

Step-by-Step: How to Choose the Right Model

Step 1: Check the electrical and site constraints

Total power is the biggest published difference inside the B-series. OFS06B-1 at 1500 W is the most conservative option for a guesthouse or small wellness room. OFS06B-2 at 1850 W is the logical next step if more heat input is needed. OFS06B-4 at 2300 W demands a higher-capacity circuit. OFS06A-5 at 3000 W is the most demanding in this group. The supplier does not specify heat-up time, cabin volume or recommended room size in the data used here, so have an electrician review the available supply before choosing a power rating.

Step 2: Compare heater layout with the intended experience

The B-series models specify far infrared heating plate plus box. OFS06A-5 specifies far infrared heating plate. The practical difference is in how the supplier describes the distribution of heat sources. If your project requires a particularly detailed heat-coverage plan, ask OCEAN FUTURE for the internal layout drawing of each model and compare it against the number and placement of seats for the planned installation.

Step 3: Decide indoor versus outdoor placement early

The four units in this comparison are not listed as outdoor sauna rooms. They do not carry the outdoor pentroof seen in OCEAN FUTURE's OFS06C line. If your installation is outdoors and exposed to weather, the selection should move to an explicitly weatherproof or outdoor-rated model such as the OFS06C series with pentroof. Using an indoor model outside would create avoidable risk.

Step 4: Confirm material and finish requirements

Once the power band is clear, choose the interior wood from the published options: hemlock, aspen or red cedar. For a hospitality brand, consistency matters. Large projects should request color samples and, if possible, a finished section of the wood surface to evaluate how it looks once the painted panels and tempered glass are combined with the wood.

Step 5: Use procurement requirements as the final filter

OCEAN FUTURE supports OEM and ODM production globally. The minimum order quantity is 1 set. Typical production lead time is 30 to 40 days, with a monthly production capacity of 400 sets. The factory states 100% testing for quality control and offers remote guidance after shipment. Payment is commonly T/T with a 30% deposit and 70% balance before shipment. These terms are useful when you move from model selection to supplier contracting.

Use Cases in Hotel, Guesthouse, Wellness and Spa Installations

The published application field for these models is identical: hotel and hospitality industry, guesthouse, wellness and commercial club, and spa facilities. This does not mean all four should be treated as fully interchangeable. It means they were positioned by the manufacturer as commercial-grade indoor infrared rooms rather than as home-only products.

OCEAN FUTURE also records a commercial spa case in Germany involving 20 sets that included the OFS06B-5 and OFS06C-4 models. The supplier-reported result highlights stable operation, consistent heating, reliable performance, low noise, energy efficiency and durable construction. That case is useful context for buyers who are evaluating OCEAN FUTURE for a multi-unit hospitality project.

Compliance and Documentation Considerations

For European installations, the relevant product documentation should be verified before shipment. In the supplied certificate records, OCEAN FUTURE lists EMC Compliance certificate No. STUEMO250300017HS and CE-EMC certificate No. STUEMO250300016HS, both issued by Guangzhou STU Hengchuang Testing Service Co., Ltd. for sauna room products. Buyers should request the model-specific declaration or certificate annex before installation to ensure the exact unit matches local requirements.
