Commercial Sauna Suppliers New Zealand: 2025 Guide
May 23, 2026 · 13 min read
TL;DR — The Bottom Line
New Zealand's commercial sauna market is led by a handful of specialist design-build firms (Sauna & Steam, NZ Sauna & Steam, Sauna People), aquatic infrastructure players importing premium European equipment (Coombes Aquatics with EOS), and modern wellness-tech brands offering infrared and hormetic solutions. When selecting commercial sauna suppliers New Zealand operators should evaluate compliance with NZ Building Code, IP-rated commercial heaters, warranty terms, lead times, and after-sales servicing — not just upfront cost.
New Zealand's wellness sector is experiencing unprecedented growth, with hotels, gyms, apartment developments, and boutique retreats all integrating sauna and steam facilities as standard amenities. For architects, developers, and facility operators across Australasia, choosing the right partner from the pool of commercial sauna suppliers New Zealand has to offer can be the difference between a 20-year asset and a five-year liability. This comprehensive guide examines the leading suppliers, the technical specifications that matter, and the procurement framework Wellnesswares recommends for serious commercial projects.
Quick Facts

- Expected lifespan with proper maintenance: 15–25 years
- Average commercial project cost: NZ$25,000–NZ$150,000+ depending on size and finish
Why the Commercial Sauna Market in New Zealand Is Different
Unlike many global markets dominated by mass-market residential brands, the commercial sauna suppliers New Zealand landscape is shaped by three forces: a small but sophisticated hospitality sector, demanding seismic and weatherproofing requirements, and a growing wellness-conscious consumer base willing to pay premium prices for authentic Finnish-style experiences. This has produced a supplier ecosystem heavy on bespoke design-build firms and lighter on plug-and-play imports.
For architects and developers in Australasia, this means the procurement conversation is rarely "which model do I buy?" — it's "which partner do I trust with the design, fabrication, installation, and ongoing service of a system that will run 12 hours a day for two decades?" That partner selection process is what separates successful wellness venues from those plagued by downtime, failed heaters, and unhappy guests.
At Wellnesswares we work alongside many of these suppliers and have developed detailed selection criteria you can review in our commercial sauna buyer's guide, which covers everything from electrical loading to bench ergonomics.
The Leading Commercial Sauna Suppliers New Zealand Operators Should Know
Below is an evidence-based overview of the most established commercial sauna suppliers New Zealand currently has in market, drawn from public project portfolios, supplier websites, and industry consultation.
1. Sauna & Steam (Auckland)
With 25+ years of experience, Sauna & Steam is positioned as a "premier" design-build specialist focusing on hotels, resorts, gyms, and high-end residential. Their end-to-end model — design, supply, install, project manage, service — makes them a natural fit for complex hospitality projects where the sauna integrates with steam rooms, pools, and spa zones.
2. NZ Sauna & Steam (Auckland)
A direct competitor to Sauna & Steam with a similar 30-year pedigree, NZ Sauna & Steam specialises in custom-built rooms for residences, hotels, wellness centres, and apartment complexes. Their strength lies in integrating new wellness rooms into existing spa and pool infrastructure — a critical capability for refurbishment projects.
3. Sauna People (NZ-wide)
Branded as "New Zealand's leading supplier of quality Finnish saunas, for over 30 years," Sauna People focuses on authentic Finnish saunas, including premium outdoor units. Architects looking for traditional, heritage-grade Finnish aesthetics often default to this supplier.
4. Coombes Aquatics (CAL)
The sole NZ agent for German manufacturer EOS, Coombes Aquatics is the primary gateway for premium European commercial-grade heaters, controls, and steam generators. Their broader aquatic infrastructure expertise makes them a strong choice for council pools, aquatic centres, and large-scale gyms where the sauna is part of a larger water-treatment project.
5. Sustainable Saunas
For eco-lodges, retreats, and wellness farms, Sustainable Saunas offers high-quality traditional outdoor saunas with strong sustainability credentials. They serve a niche but growing segment of operators whose brand narrative depends on ecological responsibility.
6. Cedar Spring Recreation
A value-focused, manufacturer-direct supplier of prefabricated outdoor Finnish-style saunas. Strong for small commercial operators — Airbnb hosts, glamping sites, boutique gyms — who need a quick, well-priced "just add power" solution.
7. Found—Space
Found—Space leads the "hormetic technologies" segment with app-controlled infrared saunas and ice baths. Ideal for tech-forward commercial concepts that want data, remote control, and structured wellness-program integration.
8. Kiva Wellness
Kiva specialises in premium commercial infrared saunas designed specifically for gyms, spas, and wellness centres — a focused product range without the design-build complexity.
9. Alpine Spas
A high-volume retailer of infrared, traditional, and wood-fired units suitable for small commercial environments. Best for PT studios, small gyms, and boutique accommodation where budget and lead time are tight.
For projects above NZ$50,000 with integrated steam and pool requirements, the design-build specialists — Sauna & Steam, NZ Sauna & Steam, or Coombes Aquatics (with EOS equipment) — are the proven choices. They handle seismic engineering, council consents, and multi-trade coordination that off-the-shelf brands cannot.
Traditional vs Infrared: What Commercial Sauna Suppliers New Zealand Recommend
One of the most consequential early decisions is choosing between traditional Finnish (steam/löyly) saunas and infrared cabins. Each has distinct commercial implications.
Traditional Finnish Saunas
- Operating temperature: 80–100°C
- Power draw: 6–18 kW depending on room size
- Authentic löyly experience attracts higher-paying guests
- Heavier construction; benefits from professional install
- Longer lifespan with proper ventilation
Infrared Saunas
- Operating temperature: 45–65°C
- Power draw: 1.6–3 kW for small commercial units
- Lower running costs and faster heat-up
- Smaller footprint; easier retrofit
- Strong appeal to wellness/recovery markets
Most commercial sauna suppliers New Zealand stocks now offer both, and many high-end venues install one of each to broaden their guest appeal. For a deeper comparison, our team has published a detailed analysis at traditional vs infrared sauna comparison.
How to Evaluate Commercial Sauna Suppliers New Zealand Offers
Choosing among commercial sauna suppliers New Zealand has on offer requires a structured evaluation framework. Below is the eight-point checklist Wellnesswares uses with our architect and developer clients.
- Commercial track record: Ask for at least three completed commercial projects of similar scale, ideally with site visits.
- Heater specification: Verify the heater is commercial-rated (continuous duty, not residential cycling). EOS, Harvia Pro, and Tylö Sense are benchmark brands.
- Compliance documentation: NZ Building Code clauses E3 (internal moisture), G4 (ventilation), G9 (electricity), and seismic standards must be addressed.
- Warranty terms: Look for 5+ years on cabinetry and 2+ years on heaters under commercial loading.
- Service network: What's the response time if the heater fails on a Friday evening?
- Materials traceability: Western red cedar, Nordic spruce, or thermo-aspen — and where is it sourced?
- Lead time transparency: Custom builds typically need 8–16 weeks; insist on a written schedule.
- Project management capability: For complex sites, does the supplier coordinate with builders, electricians, and ventilation contractors?
Commercial Sauna Suppliers New Zealand Pricing & Cost Benchmarks
Pricing in the New Zealand commercial sauna market spans a wide range. Below are realistic 2025 benchmarks Wellnesswares has observed across recent commercial projects.
| Project Type | Typical Investment (NZ$) | Lead Time |
|---|---|---|
| Small boutique gym infrared cabin (2–3 person) | $8,000–$18,000 | 2–6 weeks |
| Mid-tier hotel traditional sauna (6–8 person) | $25,000–$55,000 | 8–12 weeks |
| Custom hotel sauna + steam suite | $60,000–$120,000 | 12–16 weeks |
| Aquatic centre commercial sauna (15+ person) | $80,000–$200,000+ | 16–24 weeks |
| Outdoor barrel/cabin commercial sauna | $15,000–$45,000 | 4–10 weeks |
Pricing variability comes from three drivers: timber grade (clear cedar versus knotty pine has a 2–3x cost differential), heater brand (entry-level Finnish heaters vs EOS commercial systems), and finish-out complexity (LED chromotherapy, glass facades, custom benches).
Plan for 2–4% of capital cost per year for routine maintenance — heater element replacement every 3–5 years under commercial loading, timber re-oiling annually, ventilation cleaning quarterly, and control system updates. Reputable commercial sauna suppliers New Zealand operators rely on will provide a documented service plan as part of the contract.
The Architect & Designer Perspective: Specifying for Commercial Performance
For architects specifying a commercial sauna, the decision extends well beyond aesthetics. Key technical considerations include:
Structural and seismic loading
New Zealand's seismic environment demands that heavy sauna stoves (often 100kg+) are properly fixed and that the surrounding structure can handle dynamic loading. Suppliers without seismic engineering experience are a red flag.
Ventilation and moisture management
A commercial sauna running 12 hours daily produces substantial moisture. Cross-ventilation, vapour barriers, and dehumidification strategy must be designed in from day one — not retrofitted after timber starts warping.
Acoustic isolation
In apartment developments and hotels, the heater fan noise and bather conversation must be acoustically isolated from adjacent guest rooms. This requires double-stud walls, isolated floor structures, and carefully detailed door seals.
Accessibility
NZS 4121:2001 accessibility standards apply to many commercial premises. At least one sauna in a multi-cabin facility should typically allow wheelchair access.

Imported vs Locally-Built: Which Path Should You Choose?
A persistent question among commercial sauna suppliers New Zealand operators must navigate is whether to source a locally-fabricated custom room or import a prefabricated European or North American unit.
Locally-built advantages
- Tailored to exact site dimensions and ceiling heights
- Faster service response and easier warranty claims
- Direct relationship with installer and project manager
- Easier to integrate with existing pool/spa infrastructure
Imported (e.g. EOS, Klafs, Tylö) advantages
- Premium European engineering and electronics
- Strong aesthetic consistency across global brand venues
- Sometimes lower unit cost for standardised models
For most NZ commercial projects, the optimum is a hybrid: local design-build supplier integrating European-grade heating and control equipment (often EOS via Coombes Aquatics, or Harvia/Tylö via direct importers). This combines local accountability with global engineering quality.
Quotable Insights for Project Decision-Makers
"The cheapest commercial sauna almost always becomes the most expensive one — through downtime, warranty disputes, and premature timber failure within five years."
"In New Zealand's commercial sauna market, the supplier's service network matters more than the brochure — a heater that fails on a Friday with no local support costs you a weekend of bookings."
Frequently Asked Questions
Who are the top commercial sauna suppliers New Zealand has to offer?
The leading commercial sauna suppliers New Zealand operators rely on include Sauna & Steam, NZ Sauna & Steam, Sauna People, and Coombes Aquatics (as the EOS agent). For infrared-specific commercial applications, Kiva Wellness and Found—Space lead the market. Each suits different project scales and aesthetics.
What is the difference between a residential and commercial sauna?
Commercial saunas are engineered for continuous, high-frequency use — typically 8–14 hours daily across many users. They use commercial-grade heaters with reinforced elements, heavier-duty controls rated for thousands of cycles, denser timber specifications, and code-compliant ventilation. A residential sauna placed in a commercial setting will typically fail within 2–3 years.
How long does it take to install a commercial sauna in New Zealand?
Lead times vary significantly: prefabricated outdoor units can be installed in 4–8 weeks, mid-size custom rooms typically take 8–12 weeks from contract to commissioning, and large bespoke wellness suites in hotels or aquatic centres usually require 16–24 weeks including consents and integration with other building services.
Do commercial saunas in New Zealand require building consent?
Most commercial sauna installations require building consent under the NZ Building Act, particularly when structural alterations, new electrical loads above 10kW, or significant plumbing/ventilation changes are involved. Reputable commercial sauna suppliers New Zealand councils approve will manage this consent process as part of their service.
What's the typical lifespan of a commercial-grade sauna?
With proper maintenance — annual timber treatment, quarterly ventilation servicing, heater element replacement every 3–5 years — a commercial sauna built by a quality NZ supplier should deliver 15–25 years of reliable service. The heater is the highest-wear component; the cabinet itself often outlasts multiple heater generations.
