If you’ve seen an outdoor steam sauna at Costco, it’s easy to be drawn in by the price, convenience, and brand name recognition. Costco offers a few select outdoor saunas in their seasonal inventory and online store, but are these models really the best choice for long-term wellness, value, and performance?
This in-depth guide compares Costco’s offerings with those of dedicated online sauna retailers. We’ll dive into the hidden differences in quality, support, and customization that can affect your sauna experience—and explain why you might want to think twice before purchasing a steam sauna from a big-box warehouse.
What Kind of Outdoor Steam Saunas Does Costco Sell?
Costco typically stocks 1–2 sauna brands per season, with the following characteristics:
- Mid-range pricing (usually $2,500–$4,000)
- Fast shipping and easy checkout
- Limited selection (few models to choose from)
- Basic customer support
- No product customization or configuration
Most Costco saunas are pre-built packages that appeal to the mass market. While the value seems good at a glance, the deeper you look, the more important differences emerge.
Why You Should Be Cautious About Buying a Steam Sauna from Costco
1. Limited Product Knowledge & Support
Warehouse retailers don’t specialize in wellness equipment. If you have questions about installation, heater specifications, EMF levels, or wood care, Costco’s customer service team won’t be equipped to help.
In contrast, online sauna retailers like InHouseWellness.com and InfiniteSauna.com have experts on staff who can help you choose the right model based on:
- Climate and location
- Electrical requirements
- Health goals
- Heater type (wood-fired vs electric)
2. Lack of Customization
Costco’s sauna kits are pre-selected bundles—what you see is what you get. That means:
- No wood upgrades
- No heater swaps (e.g., switching to Harvia or HUUM)
- No add-ons like chromotherapy, salt panels, or extra benches
Online retailers let you tailor your sauna with:
- Custom wood types (Cedar, Hemlock, Thermowood)
- Specific heaters and control systems
- Accessories like ergonomic backrests or glass wall upgrades
3. Inferior Heater Options
Most Costco steam sauna packages use private-label or low-tier heaters with minimal certifications. These units:
- Take longer to heat up
- May not reach or hold target temperature
- Offer limited control features or safety shutdown systems
Dedicated sauna suppliers typically carry ETL/UL-listed heaters from brands like Harvia or Scandia, which:
- Heat quickly and efficiently
- Offer programmable timers and temperature controls
- Are built for decades of safe use
4. Warranty and Support Limitations
Costco’s return policy is generous—but it’s not a long-term warranty. If your sauna has electrical issues or wood warping after 12 months, you’ll likely be dealing directly with the unknown manufacturer (who may not even offer U.S.-based service).
Premium online retailers:
- Offer multi-year structural and electrical warranties
- Provide replacement parts
- Can walk you through setup and troubleshooting
- Have dedicated sauna technicians and electricians on call
5. Hidden Costs
While Costco’s price looks low, it often excludes:
- Electrical hookup (240V lines or GFCI installation)
- Foundation prep (concrete pad or drainage)
- Delivery beyond curbside
- Optional upgrades (lighting, speakers, insulation)
- Free accessories like buckets, ladles, or backrests
Online retailers often provide:
- Full transparency of total installed cost
- Free bonus items like wooden backrests, thermometers, buckets, and ladles
- Bundled offers that provide more value at the same or lower price point
6. Better Pricing with Competitive Pressure
Costco’s buying process doesn’t involve negotiation or brand competition. By contrast, specialty online sauna retailers often:
- Compete on pricing and service
- Offer price match guarantees
- Run seasonal promotions and discounts
This means that even when the same model is available, you’ll often pay less through an online sauna dealer—and get more.
7. Better Post-Purchase Experience
Once your Costco sauna is delivered, you’re largely on your own. In contrast, online sauna retailers:
- Provide installation walkthroughs and manuals
- Offer post-purchase tips for wood care, ventilation, and maintenance
- Check in after delivery to ensure customer satisfaction
The Illusion of Value at Big Box Stores
Costco and similar retailers often sell based on the illusion of convenience:
- Fast shipping
- “Instant savings”
- Mass-market appeal
But what you sacrifice is:
- Durability
- Customization
- Expert guidance
- Warranty support
- Free accessories
Online retailers compete directly with each other—so they’re forced to offer better pricing, better customer service, and better models. In fact, many of the brands sold at Costco can be found cheaper through trusted sauna dealers with better service and warranty coverage.
Real-World Scenario: You Like the Sauna at Costco. Now What?
If you’ve seen a sauna at Costco that looks appealing, look up the brand and model—and then search for it through premium sauna retailers. In most cases, you’ll:
- Pay the same or lower price
- Get better heater and accessory options
- Receive free upgrades like backrests or buckets and ladles
- Have access to real setup help and long-term support
Retailers like InHouseWellness.com and InfiniteSauna.com often carry similar or better models—with verified wood types, upgraded heating systems, and transparent EMF and safety specifications.
