Yes — Costco saunas are generally worth buying if you find the model and timing right. Costco carries recognized brands (Dundalk LeisureCraft, Dynamic Saunas, Harvia) at 20–30% below typical retail, with free shipping. The catch: selection is seasonal and changes frequently, so availability isn't guaranteed.
Costco has become a surprisingly significant destination for home sauna shoppers. The company offers both barrel saunas and infrared sauna cabinets through costco.com, often at prices that are meaningfully lower than specialty sauna retailers. If you're in the market for a home sauna and have a Costco membership, it's worth checking their current inventory before buying elsewhere.
What Saunas Does Costco Carry?
Costco's sauna inventory changes seasonally and by availability. Historically and currently, they've carried:
Barrel Saunas
Dundalk LeisureCraft barrel saunas — Dundalk is a Canadian manufacturer considered one of the best in the barrel sauna category. Their saunas use solid western red cedar and are built to last 20+ years with proper care. Costco has carried Dundalk barrel saunas at prices ranging from $2,800–$4,500 depending on size (4-person through 6-person models). Comparable Dundalk saunas through specialty retailers typically run $3,500–$6,500 — Costco's pricing represents a genuine 20–35% discount.
Barrel sizes commonly available at Costco: 7-foot by 7-foot (4-person), 7-foot by 9-foot (6-person). Both include electric heater and accessories.
Infrared Sauna Cabinets
Dynamic Saunas — Costco regularly carries Dynamic Saunas, a mid-range infrared sauna brand. These are popular because they sit in the middle ground between cheap/unreliable budget options and premium brands like Sunlighten or Clearlight. Dynamic Saunas at Costco typically range from $1,200–$2,500 for 1–4 person models. They use carbon fiber heating panels, are made from Canadian hemlock, and typically plug into a standard 120V outlet for smaller models.
Harvia — Harvia is a well-regarded Finnish sauna brand. Costco has periodically carried Harvia products (primarily heaters and some complete units). If you see a Harvia sauna at Costco, it's worth serious consideration — Harvia is a trusted European brand with a long track record.
Costco Sauna Prices vs. Retail

What to Know Before Buying a Sauna from Costco
Shipping and Delivery
Costco offers free shipping on sauna purchases, which is a significant value add — these are heavy items (200–600 lbs depending on size). Most are delivered via freight carrier to your curb; you'll need to handle moving it to your installation location yourself or hire help.
Assembly
Costco saunas arrive as pre-cut kits that you assemble. Barrel saunas can be assembled in 4–8 hours by two people following the instructions. Infrared cabinets typically assemble in 1–3 hours. If you've built flat-pack furniture, you can handle this.
Installation Requirements
Most 1–2 person infrared cabinets from Costco plug into a standard 120V/15A or 20A outlet. Larger infrared cabinets and barrel sauna heaters often require a 240V/30A or 240V/60A circuit — this requires an electrician. Budget $400–$1,200 for electrical work if needed.
Return Policy
Costco's return policy is one of the best in retail — essentially unlimited for most items. However, large freight items like saunas may have restocking or return freight complications. Verify the specific return terms for the sauna you're considering before purchasing.
Availability is Not Guaranteed
Costco's sauna inventory is seasonal and varies significantly. The best selection tends to appear in late spring/early summer, with some availability year-round online. If you see a model you want at a good price, buying promptly is advisable — popular models sell out.
When a Costco Sauna Is NOT the Right Choice
- If you need specific features: Costco's selection is limited. If you need a specific heater, wood type, size, or feature set (like chromotherapy lighting, full-spectrum infrared, or a specific panel configuration), a specialty retailer gives you more options.
- If you want premium infrared technology: Sunlighten and Clearlight — the top-tier infrared sauna brands known for full-spectrum infrared and superior EMF shielding — aren't sold through Costco. For these brands, you'll buy direct or through specialty dealers.
- If the timing is wrong: If the sauna you want isn't currently available at Costco, waiting for it may mean a long delay. Sometimes buying from a specialty retailer at full retail is better than waiting months.
