Before You Buy
Costco is great for paper towels.
Costco carries Dynamic Saunas, Maxxus, and Golden Designs. So do we. But here's what makes a $1,899 health purchase different from a 48-pack of paper towels: what happens after you own it.
"For a wellness investment you'll use daily for the next decade, you want someone who answers the phone — and knows what to do when you call."
At Iridescent Home, we're an authorized dealer for every brand we carry. That means your warranty is valid, your return is backed, and when you call us, you'll speak to someone who works with these exact units every day — not a general merchandise returns desk.

What Costco actually sells — and what it costs
Costco's sauna selection is a rotation, not a catalog. At any given time it includes a handful of infrared cabins from Golden Designs Inc. — the same manufacturer behind the Dynamic and Maxxus lineups we stock year-round — alongside traditional and outdoor models from other suppliers.
On price: when a comparable 2-person low-EMF infrared model appears in Costco's rotation, it has typically listed around $1,799 — about $100 below our $1,899 authorized-dealer price for the same class of unit. That $100 is the entire decision. At Costco it buys their return counter. From an authorized dealer it buys a 5-year manufacturer warranty that's actually valid, a specialist who answers the phone, and 130 models to choose from instead of this quarter's rotation.
When Costco is honestly the right choice
We sell against Costco, and we'll still say it: if the exact model you want is in their current rotation, you value Costco's famously liberal return policy more than manufacturer warranty coverage, and you don't expect to need product support in year three — Costco is a rational place to buy a sauna. Before you commit, check three things: whether the listing states a measured EMF rating (many don't), who honors the warranty after Costco's return window closes, and how freight damage is handled at delivery.

This Matters More Than Price
What "Unauthorized Retailer" Actually Means
Dynamic Saunas, Maxxus, and Golden Designs are premium brands with real warranty programs — but those warranties are only valid through authorized dealers. Costco is not authorized by these brands.
- Buy from us — your warranty is fully honored. The manufacturer knows us.
- Buy from Costco — a heater element fails at year 2. Manufacturer says: unauthorized sale, no coverage.
- Costco's return window closes. You own a $1,899 unit with a broken heater and no recourse.
- Our customers call the manufacturer and are recognized. We advocate for you.
This is not hypothetical. Unauthorized retailer purchases are the #1 reason warranty claims are denied in the home sauna category.

Common Questions
Everything You're Wondering
Answered honestly, including the ones where Costco might have an edge.
Are Costco infrared saunas worth it?
Costco infrared saunas can be worth it for budget-focused buyers — build quality is generally decent and membership pricing is competitive. The trade-offs: Costco is not an authorized dealer for Dynamic, Maxxus, or Golden Designs, so the manufacturer warranty may not be honored, and buyers frequently report 3–5 week waits for replacement parts with support bounced between Costco and the manufacturer. Hidden costs such as curbside-only freight, electrical prep, and self-assembly also apply. Buying the same brands from an authorized dealer like Iridescent Home preserves the full 5-year warranty and gives you direct expert support after delivery.
Is Iridescent Home cheaper than Costco?
In most cases, yes — and we back it with a lowest-price guarantee. Because we specialize exclusively in home wellness, we negotiate better margins on the same brands. If you find a lower price anywhere on an identical, in-stock model from an authorized dealer, we'll match it.
How much does a sauna cost at Costco?
It depends on the current rotation, but comparable 2-person low-EMF infrared models have typically listed around $1,799 — roughly $100 below the $1,899 authorized-dealer price for the same class of unit. Larger and full-spectrum cabins run higher. The catch isn't the sticker price: it's that the manufacturer's 5-year warranty requires purchase from an authorized dealer. For the full breakdown of what drives sauna pricing, see our home sauna cost guide.
Do I lose my warranty if I buy from Costco?
Yes — manufacturer warranty coverage requires purchase from an authorized dealer. Costco is not authorized for Dynamic, Maxxus, or Golden Designs. If something fails after year one, you're on your own. We are authorized. Your warranty is recognized from day one.
What brands do you carry that Costco also sells?
We carry Dynamic Saunas, Maxxus, and Golden Designs Inc. — the exact brands that appear at Costco periodically. We stock the full lineup year-round, not a seasonal rotation. You can compare models side-by-side and speak to an advisor who knows every unit.
What is your return policy?
30-day returns. Costco's policy is generous for returning to Costco — but if a unit is defective after 30 days, you're dealing with a manufacturer that doesn't recognize you as an authorized customer. Our authorized status means we advocate for you with the brand directly, long after purchase.
Can I get financing at Iridescent Home?
Yes. We offer 0% APR through Shop Pay — the Dynamic Gracia starts at $158.25/month with no interest for 12 months. Checking your rate has no impact on your credit score. Costco does not offer specialized financing on sauna purchases.
Who do I call if something goes wrong?
You call us: (307) 201-4597, 9am–5pm MT, every day. You'll speak to someone who has handled hundreds of sauna deliveries. We know exactly what to do, and so does the manufacturer when we call on your behalf.
