The Peak Fuji is a two-person indoor infrared sauna designed for households that want shared sessions without moving to a large three-person cabin. It combines full-spectrum infrared heat, an included full-body red-light panel, Wi-Fi app control, and premium Canadian red cedar in a 53-by-44-inch footprint.
Peak currently lists the Fuji for $8,250, with free freight delivery in the continental United States. That places it firmly in the premium category. The Fuji’s value depends on whether two-person capacity, cedar construction, app control, and the included red-light system matter enough to justify its price and dedicated 20-amp electrical requirement.

Quick verdict
The Fuji is a strong fit for a couple or household that expects to use an infrared sauna together and wants a cabin that feels more substantial than a compact one-person model. Its 49-inch-wide interior provides a shared bench, while the red cedar, eight heating panels, app controls, and full-height red-light panel create a polished home-wellness setup.
The main practical drawback is electrical preparation. Unlike the one-person Shasta, the Fuji requires a dedicated 120V/20A circuit with a NEMA 5-20P receptacle. Buyers should confirm the circuit before ordering rather than assuming an existing household outlet will work.

Two-person capacity: useful or cramped?
The Fuji’s 49-by-40-inch interior is designed for two seated adults. It is a meaningful step up from the Shasta’s one-person cabin without requiring the space of Peak’s larger Matterhorn.
Two-person labeling does not guarantee that every pair will find the bench equally comfortable. Body size, shoulder width, preferred sitting position, and session length all affect the experience. If possible, compare the interior measurements with a bench or seating area in your home before ordering.
For one frequent user, the extra width can provide welcome elbow room. For a couple, the key question is whether you genuinely expect to share sessions. If most sessions will be solo, the lower-priced Shasta may offer better value and easier electrical placement.
The dedicated 20-amp requirement
Peak specifies 120V, 20A, and 2,050 watts for the Fuji, using a NEMA 5-20P plug. A dedicated 20-amp circuit is required. This is not the same as plugging the sauna into any ordinary 15-amp wall outlet.
Confirm the intended room’s circuit, receptacle, and outlet location before ordering. A licensed electrician can determine whether an existing circuit is appropriate or whether a new one is needed. Do not use an extension cord, power strip, or adapter unless Peak’s current manual explicitly permits it.
Our infrared sauna electrical requirements guide explains the differences among standard 15-amp, dedicated 20-amp, and 240-volt installations.
Full-spectrum infrared and red light
The Fuji uses eight heating panels that combine carbon far-infrared panels with halogen and quartz emitters. Peak lists near-, mid-, and far-infrared wavelengths and a maximum cabin temperature of up to 150°F.
An interior full-body red-light panel is included on the front wall. Peak lists eight wavelengths and app-based programs. These are wellness features, not a substitute for medical care. Anyone with a health condition, taking medication, pregnant, or uncertain about heat or light exposure should seek appropriate professional guidance before use.
Controls and comfort features
The sauna can be controlled through interior and exterior touchscreens or the Peak Wi-Fi app for iOS and Android. Remote starting and scheduling can be convenient because the cabin needs preheating time before a session.
The Fuji also includes two Bluetooth speakers, chromotherapy lighting, an oxygen-ionization system, and a foot heater. These extras add atmosphere, although the most important buying factors remain cabin fit, heat performance, electrical readiness, and the likelihood of frequent use.
Red cedar construction
The Fuji is made with Canadian red cedar. Cedar has a distinct aroma and a warmer, more varied appearance than pale hemlock. Some buyers consider that part of the premium experience; others may prefer a lighter, more neutral cabin.
Wood is a natural material, so grain and color variation should be expected. Anyone sensitive to strong wood aromas should consider whether cedar is the right choice before placing the sauna in a bedroom, office, or other frequently occupied space.
Size and room planning
At 53 inches wide, 44 inches deep, and 75 inches high, the Fuji needs more than its stated floor footprint. Allow room for assembly, the door swing, ventilation clearances specified in the manual, and access to the dedicated outlet.
Measure the entire delivery route as well as the final room. Check exterior doors, hallways, stairs, corners, and ceiling height. Peak identifies the Fuji as an indoor sauna, so do not assume it is suitable for an outdoor patio, damp garage, or unconditioned structure.

Delivery and assembly
Peak currently includes free freight delivery within the continental United States. The sauna ships in a protective crate and weighs 385 pounds when assembled. Curbside freight does not mean the carrier will move every panel into your room, assemble the cabin, or remove the packaging.
Plan how the crate will be received, who will move the components, and where packaging will go. Inspect the shipment according to Peak’s delivery instructions before accepting it.
The cabin uses clasp-together panel construction. Peak’s detailed specifications say two adults can typically complete assembly in 60–90 minutes with minimal tools, while another product summary says about two hours. Allow additional time for uncrating, inventorying parts, moving panels, and reviewing the manual.
Warranty and ownership
Peak’s written residential warranty gives seven years of coverage to heating elements and the cabinetry and wood structure; three years to controls, power supply and the red-light panel; and one year to lighting, sound, accessories and Wi-Fi/app connectivity. Labor and some shipping costs are excluded. Coverage is non-transferable and subject to the full policy. Lifetime U.S.-based support is separate from parts coverage. Read Peak’s current warranty terms before purchasing.
Routine care should follow the owner’s manual. Use towels to protect the bench, allow the cabin to dry after sessions, and avoid unapproved household chemicals on the cedar, electronics, or heating components.
Fuji versus Shasta or Matterhorn
The Fuji occupies the middle of Peak’s most straightforward size comparison:
- Shasta: one person, 42 × 40 inches, standard 120V/15A connection.
- Fuji: two people, 53 × 44 inches, dedicated 120V/20A circuit.
- Matterhorn: three people, larger footprint, dedicated 240V/20A service.
Choose the Fuji when shared sessions justify the added cost and electrical preparation. Choose the Shasta when compact size and standard-outlet convenience matter more. Consider the Matterhorn if three-person capacity or a roomier shared bench is the priority.
Read our Shasta vs. Fuji vs. Matterhorn comparison or our detailed Peak Shasta review before deciding.
Who should buy the Peak Fuji?
The Fuji makes the most sense if you:
- expect two people to use the sauna together;
- want the aroma and appearance of Canadian red cedar;
- value app control and an included full-body red-light panel;
- can provide a dedicated 120V/20A circuit; and
- have a clear freight-delivery and assembly plan.
It may not be the right choice if most sessions will be solo, you need a standard 15-amp connection, the delivery route is tight, or you want a lower-cost heat-only sauna.
Final thoughts
The Peak Fuji’s strongest argument is that it turns a premium infrared-sauna routine into something two people can share. Its red cedar cabin, full-spectrum heat, integrated red-light panel, app controls, and included delivery create a well-equipped package.
Its $8,250 price and dedicated 20-amp requirement demand careful planning. Measure the room and delivery route, confirm the electrical work, review the written warranty, and decide whether two-person use will be frequent enough to justify stepping up from the Shasta.
