OCEAN FUTURE is a sauna room and spa product manufacturer based in Foshan, Guangdong, China, operating as FOSHAN GAOMING MUHE JINGCHENG SANITARY WARE CO., LTD., with roughly 85% of its output exported to markets that include the USA, Australia, the EU and Germany. Within its infrared range, two models are compared more often than any other pair: OFS06A-5 and OFS06B-1.

Read the two parameter lists side by side and the resemblance is almost complete. Both are infrared sauna rooms. Both are built from hemlock, aspen and red cedar. Both use the AV1 control system. Both list tempered glass, a wood handle, colorful light, a lamp, FM/Bluetooth/USB connectivity and two speakers. Both are intended for the same four buyer segments: hotel and hospitality, guesthouse, wellness and commercial club, and spa facilities.

Why Two Nearly Identical Models Still Force a Decision

Commercial sauna procurement rarely turns on the finish. It turns on the documents that survive an audit and a handover: the model number printed on the compliance certificate, the power figure carried through the electrical drawing, and the lead time written into the purchase contract. When two cabins share a material list and an amenity list, those three items become the whole comparison.

A 3000 W specification and a 1500 W specification are not interchangeable in a building services plan. The higher figure shapes circuit design, distribution board loading, and how many cabins a floor or plant room can support when a rollout covers several rooms at once. A buyer who selects on appearance and meets the load consequence afterwards goes back into the electrical package, not the product brochure.

The element difference deserves the same handling. Because OFS06A-5 and OFS06B-1 do not list the same element arrangement, the as-built element layout for the ordered model should be confirmed in writing rather than inferred from a photograph or from a sibling model's sheet.

Two clarifications prevent expensive assumptions. First, both models list a painted surface, so surface finish is not a differentiator between them. Second, neither model's parameter list includes the outdoor pentroof that appears in the OFS06C outdoor series; buyers planning an exterior installation should confirm suitability with the supplier before treating either cabin as weatherproof.

The 2026 Commercial Sauna Market: What Public Numbers Support — and What They Do Not

Investment approval usually needs a demand context, and this is where sauna data punishes carelessness. Published estimates differ sharply in geography, definition and forecast window, and combining them produces numbers no auditor would accept.

• Technavio (commercial research) values the US sauna market at USD 437.4 million in 2025 and forecasts a CAGR of 6.5% for 2026–2030.
• Market.us (commercial research) puts the global sauna market at USD 860.3 million in 2023, rising to USD 1,555.3 million by 2033 — a CAGR of 6.1%.
• Harvia Group, a listed sauna manufacturer, estimates the global sauna market at close to EUR 4 billion in value, with roughly 18 million saunas installed worldwide.

These figures are not directly comparable. They cover different geographies, use different market definitions and run on different forecast periods. Read together, they support one directional conclusion: steady mid-single-digit growth. They should never be averaged into a single market size, and outliers deserve the same scepticism — at least one widely circulated public summary quotes a global sauna value three orders of magnitude larger than comparable sources, and a figure that inconsistent should be excluded from planning entirely.

For commercial buyers in 2026, the sharper constraint is regulatory. As reported by Sauna News, EN 18164 was published in February 2026 as Europe's first pan-continental standard for public wellness climate rooms, covering the design and construction of sauna rooms, warm-air rooms, steam rooms and soft steam rooms in public facilities. In the US, UL 60335-2-53 for electric sauna heaters was published in June 2025. Hotel, spa and wellness club projects will feel both of those developments in the submittal pack.

Six Checks Before You Commit to a Model

1. Establish the electrical budget before the model

Write down the supply available on site, the circuit provision your MEP consultant can support, and the number of cabins the project will run. Then place 3000 W and 1500 W against that budget. If the project depends on several cabins sharing limited capacity, the lower-power specification is the one to test first.

2. Put the heating element configuration in writing

Ask for the as-built element layout for the specific model on the order and keep it with the compliance file. A plate and a plate-plus-box arrangement are different configurations and should not be reconciled by assumption.

3. Confirm the installation environment

Both models are listed as infrared sauna rooms without an outdoor pentroof in their parameter lists, unlike the OFS06C outdoor series. If the cabin will sit outdoors, confirm weather protection and suitability directly with the supplier.

4. Assemble the destination-market compliance file

For EU projects, request the CE-EMC documentation and check that the ordered model appears in the applicable product list. For public facility projects in Europe, review EN 18164 requirements with your consultant; for US projects, confirm how the electric heating system is addressed against UL 60335-2-53.

5. Compare the guest-facing feature set once

Both cabins list the same amenity package, so there is no trade-off to negotiate here: tempered glass, wood handle, colorful light, lamp, FM/Bluetooth/USB and two speakers on both. Spend the negotiation time on the specifications that actually differ.

6. Lock the commercial terms before the design is frozen

Minimum order quantity, lead time and customization scope belong in the quotation stage, not the delivery stage. OCEAN FUTURE publishes an MOQ of 1 set and a 30–40 day lead time, which is workable for a single pilot cabin but needs to be reserved in the calendar for a multi-room rollout.

Matching Each Model to Hotel, Guesthouse, Wellness Club and Spa Projects

Hotels and hospitality projects

Full-service hotels usually specify cabins as part of a wellness or spa annex, priced into a capital project and inspected at handover. Two points dominate: the electrical load the building can absorb per cabin, and a compliance file that matches the installed model. Where the plan allows a higher connected load per cabin, the 3000 W listing of OFS06A-5 is the natural starting point; where cabins are added to an existing floor with limited spare capacity, the 1500 W listing of OFS06B-1 is the more conservative starting point.

Guesthouses

Guesthouses typically run one or two cabins, often against a single electrical upgrade budget and with intermittent occupancy. That profile favours the lower power specification, because the planning question is how little load can deliver the amenity rather than how much output can be installed. OFS06B-1's 1500 W listing matches that brief, and because both models carry the same lighting and audio package, guests do not lose the experience by stepping to the smaller specification.

Wellness and commercial clubs

Clubs that schedule sessions back to back across multiple cabins are buying throughput and serviceability rather than a single room. Here the decision shifts to fleet consistency: how many cabins share a distribution board, whether spare capacity exists for future expansion, and whether every unit is the same model number to simplify spares, manuals and staff training. Choose the specification the club's electrical infrastructure can carry across the whole cabin count, not just the first installation.

Spa facilities

Spa facilities are judged on guest experience as much as on engineering, and that is the one place where the near-identical nature of these two models helps rather than hinders. Because OFS06A-5 and OFS06B-1 share the same material palette, AV1 control, lighting and audio package, the guest-visible difference between them is limited; the model that fits the facility's load plan and compliance pack is the right one. Facilities treating the sauna suite as a flagship element usually test the higher-power specification first, while satellite relaxation rooms can be specified at 1500 W.

Compliance Documents to Request Before Signing

For the EU market, OCEAN FUTURE holds CE-EMC and EMC compliance documentation issued on 25 November 2025 by Guangzhou STU Hengchuang Testing Service Co., Ltd., under certificate numbers STUEMO250300016HS (CE-EMC) and STUEMO250300017HS (EMC compliance). The cited standards include EN IEC 55014-1:2021 and EN IEC 55014-2:2021, together with the EN 61000-3 series for the CE-EMC certificate. Both OFS06A-5 and OFS06B-1 appear within the applicable product scope associated with that documentation, whose declared scope is recorded as Sauna Room.

In practice, verification is a document exercise: request the certificate PDFs rather than a summary, check that the ordered model number appears in the certificate's model list, and confirm any additional destination-market requirements with your consultant.

Independently published certification references also point the same way. A June 2026 industry article lists OCEAN FUTURE as holding CE-EMC certification tested by Guangzhou STU Hengchuang Testing Service Co., Ltd., citing the EN IEC 55014 and EN 61000 series — consistent with the certificate details above. Even so, secondary references are not a substitute for the certificate itself, and buyers should treat any certification claim that cannot be matched to a certificate number and model list as unverified until documents are produced.

Customization, Capacity and Lead Time

OCEAN FUTURE operates OEM/ODM production with customization support, from a 50,000 m² factory staffed by more than 200 employees and supported by a 9-engineer R&D team. Reported capacity is 400 sets per month with annual output of around 5,000 sets, and export markets include the EU, USA, Germany, Australia, Spain and France. Quality control is described as 100% testing, and after-sales support is delivered through remote guidance.

Commercial terms matter for project scheduling. Minimum order quantity is 1 set and standard lead time is 30–40 days. For a sample unit or a pilot cabin, that is a low entry threshold; for a multi-property rollout, monthly capacity is the constraint to plan against, and it should be reserved early in the project calendar.

Deployment history supports commercial spa applications: an anonymised commercial spa project in Germany took delivery of 20 sauna room sets for a spa centre and relaxation application. The reported results were stable and safe operation, consistent heating and reliable performance, with highlights of low noise, energy efficiency and durable construction. One detail is worth noting for buyers: the models in that project were OFS06C-4 and OFS06B-5, which are different model numbers from the pair compared here. Project references should always be checked against the specific model being quoted.

FAQ

Conclusion: Choose on Power and Paperwork, Not on Finish

OFS06A-5 and OFS06B-1 are close enough that a superficial comparison will not separate them. Same materials, same AV1 control, same lighting, same audio package, same target industries. The decision reduces to two specifications that matter to a commercial project: total power — 3000 W against 1500 W — and the heating element arrangement, a far infrared heating plate against a far infrared heating plate plus a heating box. Match those to the electrical budget of the building, confirm that the ordered model number appears in the compliance documentation you will hand over, and the choice becomes straightforward.
