What it's like to own a Fuji

The Fuji is the Peak you buy with your nose as well as your spec sheet. It's our only two-person indoor cabin in Canadian red cedar — the aromatic, naturally moisture-resistant wood prized in traditional saunas — and owners consistently mention the smell as part of the ritual. Everything else matches our hemlock two-person, the Everest: same footprint, same heating array, same full-body red light wall on the front panel, positioned for coverage while seated rather than tucked into the ceiling as a token strip.

It arrives by freight in a custom protective crate, and the clasp-together panels mean no fasteners marathon: the product page says two adults typically finish in 60–90 minutes, and a verified owner below clocked "about 1.5 hrs" from opening the box to done. Day to day you run it from the Peak Saunas app (iOS and Android) — preheat on the drive home, then adjust temperature, lighting, and session length from the bench or either touchscreen. The app carries guided red light programs for skin health, muscle recovery, and sleep optimization, plus the Peak Wellness Club, included free for life with every Peak sauna: daily guided sessions and 30-day programs, which no other sauna brand includes. Comfort kit: two Bluetooth speakers, chromotherapy, an oxygen-ionization air system, and a foot-reflexology heater.

What verified owners say

The Fuji is Peak's most-reviewed model: a 4.74/5 average across 39 verified purchase reviews on our Judge.me widget as of August 5, 2026 (brand-wide: 4.76/5 across 3,900+ verified purchase reviews). Verbatim excerpts from verified buyers:

"We've had our Fuji 2 person sauna for a couple of months. From the first call through today the staff of Peak Sauna have been superb! Assembly was just as described, quick (about 1.5 hrs) to open the box and complete the assembly. We use the sauna 1-2 times a day, it is almost addictive."

— Rich S.C., verified buyer, 5/5, July 2026

"I have been using it for two weeks and feel like my sleep quality has already improved. I am so glad I went with the 2 person size as it is big enough for my husband and I without feeling claustrophobic. Plus when it is just me I feel like I can stretch out a bit. We are impressed with the quality of the materials even the sound system is great which I didn't expect."

— Amy M., verified buyer, 5/5, July 2026

"We bought our sauna after visiting a spa, listening to several podcasts, lots of research and settled on the Peak Fuji. Absolutely the best wellness investment we have made. Everything else has improved. The only thing: we wish we'd have bought the three person just to have more space and potentially, partially lay down."

— Nick P., verified buyer, 5/5, July 2026

Honest limitations

• It needs a dedicated 120V/20A circuit. The Fuji draws 2,050W on a NEMA 5-20P plug. Most homes have or can add a 20A circuit inexpensively, but it isn't plug-anywhere like the 15A Shasta — one owner described mapping which outlets shared his 20A breaker and capping off the rest before first use.
• Two-person means seated-for-two. At 49″ of interior width the Fuji is comfortable for two seated adults, but owners who want to stretch out or partially recline tell us — in the reviews above — they'd size up to the three-person Denali.
• Assembly instructions lean on pictures. Assembly itself is consistently reported at about an hour to 90 minutes for two people, but more than one reviewer found the printed instructions thin ("if you like pictures you can pretty much figure it out," as one 4-star review put it). Our U.S.-based support team walks owners through by phone when needed.
• Freight delivery, big crate. 385 lbs in a substantial protective crate on a freight truck. Delivery is free and scheduled; plan for panel-carrying and crate disposal.
• Cedar is a preference, not an upgrade. If you'd rather have a neutral, low-aroma cabin, the hemlock Everest is $300 less with the same dimensions.

How the Fuji compares to the Sun Home Eclipse 2

The closest competing model is the Sun Home Eclipse 2, a 2-person indoor full-spectrum-plus-red-light cabin listed at $10,599 on Sun Home's site as of August 2026 — $2,349 more than the Fuji. Credit where due: Sun Home is the strongest marketer in the category (Fortune and Forbes placements, published third-party heat testing on its cabins), and the Eclipse 2 is one of the few competitors that, like Peak, integrates red light into the cabin rather than selling it as an add-on. The checkable spec differences, as of August 2026: Sun Home publishes its red light at two wavelengths (660/850nm) with no per-distance irradiance figure, versus the Fuji's 8 wavelengths (630–1060nm) with irradiance published at 6″, 12″, and 24″; the Fuji's warranty terms are published as limited lifetime on structure, wood and heating elements (defined as 7 years residential) with a 7-year red light panel; and every Fuji includes the Peak Wellness Club free for life — daily guided sessions and 30-day programs — which no other sauna brand includes. If brand awards matter most to you, Sun Home has more of them; if published light-therapy dosing and the $2,349 difference matter more, the Fuji is the stronger buy.

FAQs

Is the Peak Fuji a good sauna?

The Fuji is Peak's most-reviewed model, rated 4.74/5 across 39 verified purchase reviews as of August 2026, and one of Peak's two best sellers. At $8,250 it includes full-spectrum infrared, an aromatic Canadian red cedar cabin, a full-body XL red light panel with 8 wavelengths (630–1060nm) and published per-distance irradiance, and the Peak Wellness Club free for life. The most common owner criticism is wanting more room to stretch out — buyers who want to recline should consider the 3-person Denali.

What's the difference between the Peak Fuji and the Peak Everest?

Wood and price. Both are 2-person indoor cabins with identical dimensions (53″W × 44″D × 75″H), the same 8-panel full-spectrum heating array, the same full-body red light panel, and the same 120V/20A electrical requirement. The Fuji ($8,250) is aromatic Canadian red cedar; the Everest ($7,950) is Canadian hemlock, a neutral, low-aroma wood. Choose by nose and budget.

What electrical does the Peak Fuji need?

A dedicated 120V / 20A circuit (NEMA 5-20P plug, 2,050W draw). No 240V service is required, but the circuit shouldn't be shared with other high-draw appliances. An electrician can typically add a dedicated 20A circuit if one isn't available near the install location.

How long does Peak Fuji assembly take?

The product page states two adults typically complete the clasp-together assembly in 60–90 minutes, and verified owner reviews report the same — one owner timed it at about 1.5 hours from opening the crate to finished. Minimal tools are required.
