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 has set up hundreds of these units — not a general merchandise returns desk.
Same brands. Very different purchase experience.

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.
This is not hypothetical. Unauthorized retailer purchases are the #1 reason warranty claims are denied in the home sauna category.
Call (307) 201-4597 and you'll reach an advisor who has handled hundreds of sauna installations. Not a call center. Not a chatbot.
5-year coverage on heating elements, 1-year on the wood structure. Recognized by the manufacturer from day one.
The Dynamic Gracia is $1,899 — or $158.25/month with zero interest. Costco doesn't offer specialized sauna financing.

Some saw these at Costco first. Some spent weeks researching. Here's what they said after.
"Saw a similar unit at Costco. Did more research and found Iridescent Home. Same brand, actually a better configuration, and these guys are an authorized dealer — so if anything goes wrong, I'm covered. Setup was about 45 minutes. First session was that night."
"I use it every single day. Chronic lower back pain for years — three weeks in and I'm sleeping through the night. The unit heats super fast, the assembly took longer to unpack than to put together. I wish I'd done this sooner."
"Shipping was fast, set up was easy. Had one question about the control panel and called the number on the site. Someone answered on the second ring and walked me through it in three minutes. That's not Costco service. That's a specialty store."

Answered honestly, including the ones where Costco might have an edge.
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.
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.
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.
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.
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.
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.
You call us: (307) 201-4597, Monday–Friday 9am–5pm MT. 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.
