Quick Answer: Costco sells exactly one infrared sauna brand — Dynamic Saunas, made by Golden Designs, Inc. — with nine models currently listed on Costco.com from about $1,799 to $3,499. Costco’s own product page lists the Dynamic Gracia as a Low EMF sauna, while the Gracia sold on Amazon is Dynamic’s Ultra Low EMF tier (under 3 mG) — same name, different spec, confirmed directly against Costco’s product page. Saunas also aren’t covered by Costco’s 90-day major-appliance return policy, since that policy explicitly lists refrigerators, washers, and similar appliances — not saunas.
“Costco sauna” is one of the highest-volume searches in this niche, and for good reason: Costco’s brand trust and return reputation make it a natural first stop before spending $2,000+ on a home sauna. Here’s exactly what’s actually on Costco.com right now, what the fine print says about returns and warranty, and the one naming overlap worth double-checking before you buy.
Every Dynamic sauna currently on Costco.com
| Model | EMF class | Capacity | Price |

| Dynamic Gracia | Low EMF | 1-2 person | ~$1,799 |
| Dynamic Tuscany | Standard | 2 person | ~$1,799-$1,899 |
| Dynamic Bellagio | Low EMF | 3 person | ~$1,999 (on sale) |
| Dynamic Llumeneres | Ultra Low EMF | 2 person | ~$2,399 |
| Dynamic Toscana Elite | Ultra Low EMF | 3 person | ~$2,799 |
| Dynamic San Marino Elite | Ultra Low EMF | 2 person | Costco.com, price varies |

| Dynamic Aveiro | Full Spectrum | 2 person | ~$3,499 |
Every single one of these is a Dynamic model — Costco carries no Maxxus, no Golden Designs flagship, no traditional/barrel sauna, and no sauna blanket. If you’ve shopped this site’s best Dynamic sauna guide, that context matters: Dynamic, Maxxus, and Golden Designs are all built by the same manufacturer, Golden Designs, Inc., with Dynamic sitting at the entry tier. Costco is essentially a second retail channel for that entry tier, running its own model names in parallel with the Amazon-listed lineup.
The Gracia name is where this gets confusing
Costco’s own product page for the Dynamic Gracia 1-2 Person Low EMF Infrared Indoor Sauna (model DYN-6119-01) specs it out plainly: 7 Low EMF heating panels, 1700W, 120V/15A, Canadian Hemlock construction. Nowhere on that listing does it say “Ultra Low EMF.”
That matters because the Dynamic Gracia this site already recommends in our best Dynamic sauna guide — the Amazon-listed version — is Dynamic’s Ultra Low EMF tier, reading under 3 mG at 6-8 inches from the heating panels per Golden Designs’ published specs. Ultra Low EMF is a genuinely different, lower-emission spec than standard Low EMF; it’s the reason buyers who prioritize EMF pick the Gracia over Dynamic’s base models like the Andora or Barcelona in the first place.
So the same model name, “Gracia,” currently points to two different EMF classes depending on which retailer’s listing you’re reading. This isn’t necessarily a bait-and-switch — retailers sometimes carry channel-specific spec variants of the same badge name — but if EMF level is the reason you’re choosing a Gracia over a cheaper Dynamic model, don’t stop at the name. Open the actual spec sheet on whichever listing you’re buying from and confirm “Ultra Low EMF” (or the mG rating) is written there in black and white.
Why saunas skip Costco’s best return policy
Costco’s major-appliance policy is genuinely strong: a 90-day return window plus a 2-year warranty extension with free technical support. But that policy, per Costco’s own customer service documentation, explicitly names its covered categories — refrigerators over 10 cubic feet, washers, dryers, dishwashers, freezers, ranges, cooktops, and over-the-range microwaves. Saunas are not on that list.
That means a Costco sauna falls back to Costco’s general merchandise satisfaction guarantee rather than the extended major-appliance terms, and large freight-delivered items like a 250+ lb sauna cabin can carry different practical return logistics (freight pickup scheduling, potential restocking considerations) than a small appliance you can carry back to a warehouse yourself. None of this makes a Costco sauna a bad buy — it just means the “Costco return policy” reputation that applies to a washing machine doesn’t automatically carry over to a sauna. Confirm the specific return terms listed on the exact product page before you order.
What you actually get on warranty
The manufacturer warranty is the same regardless of retailer, because Costco doesn’t build the sauna — Golden Designs, Inc. does. Per the brand’s published warranty terms, that’s typically a 1-year limited warranty on the cabin overall, with heating elements and electronics covered longer on many models (up to 5 years on some Dynamic and Golden Designs units). That coverage follows the original purchaser and installation address with a sales receipt as proof — it doesn’t matter whether the receipt says Costco, Amazon, or Golden Designs’ own site.
Dynamic Andora 2-Person Low EMF Infrared Sauna (Amazon)
- Sits in the same price range as Costco's mid-tier Dynamic models, with a spec sheet (carbon panels, red-light therapy, Bluetooth) you can confirm before buying rather than sourcing from a warehouse floor sample.
- Amazon-direct shipping and standard Amazon return handling, instead of freight-delivery logistics for an oversized item.
- Same manufacturer (Golden Designs, Inc.) and warranty structure as every Costco Dynamic model.

Dynamic Gracia Ultra Low EMF Infrared Sauna (Amazon)
- The genuine Ultra Low EMF tier — under 3 mG at 6-8 inches from the panels per Golden Designs' published figures — if EMF class is the deciding factor, not just the model name.
- About $900 more than Costco's Low EMF Gracia, which is the real price of the lower-emission spec once you compare like for like.
- Same Canadian Hemlock construction and 120V plug-and-play setup as the Costco version.
How to shop Costco’s sauna listings without getting tripped up
- Read the spec sheet, not just the model name. Confirm EMF class, wattage, and panel count on the exact listing, especially on the Gracia.
- Don’t assume the major-appliance return policy applies. Saunas aren’t on Costco’s covered-appliance list — check the product page’s own return terms.
- Compare against the Amazon-listed Dynamic lineup before you buy. Costco’s model names (Tuscany, Bellagio, Llumeneres, and others) mostly don’t overlap with the Amazon lineup (Andora, Barcelona, Venice, Lucca), so a “which is cheaper” comparison needs the actual spec sheet, not the price alone.
- The warranty is identical either way. It’s a Golden Designs, Inc. warranty regardless of retailer, so retailer choice should come down to logistics and return terms, not warranty coverage.
- Costco’s price is fixed, not negotiable. Dealer-direct Dynamic listings can move 15-25% off list if you ask — Costco’s listed price is the price. See our sauna deals guide for how the two pricing models actually compare.
The bottom line
Costco’s infrared sauna selection is genuinely just Dynamic — the same entry-tier brand from Golden Designs, Inc. that this site already covers in depth — sold under a partly different set of model names at similar prices. The one thing worth double-checking before you buy is the Gracia: Costco’s own listing specs it as standard Low EMF, not the Ultra Low EMF tier the same name carries on Amazon. Outside of that overlap, Costco is a legitimate place to buy a Dynamic sauna, just without the extended major-appliance return window shoppers often assume applies.
