The Peak Shasta is a one-person indoor infrared
sauna designed for buyers who want a complete cabin without dedicating a
large room or installing a special electrical circuit. It combines
full-spectrum infrared heat, an included red-light panel, Wi-Fi app
control, and a compact 42-by-40-inch exterior footprint.
At the time of this review, Peak lists the Shasta for
$6,950, with free curbside delivery. That is a
significant investment for a single-person sauna, so the real question
is whether the Shasta’s easier placement, included features, and
warranty justify its price for your household.

Quick verdict
The Shasta is best for one person who wants a feature-rich infrared
sauna in a relatively compact indoor footprint. Its standard 120V/15A
plug is a major practical advantage: Peak states that it uses a NEMA
5-15P connection rather than the dedicated 20-amp or 240-volt circuits
required by many larger cabins.
Its biggest limitation is capacity. The Shasta seats one person, and
a couple who wants to share sessions should compare a larger Peak model
before committing. The sauna also weighs 305 pounds and arrives by
curbside freight, so “plug and play” does not mean effortless delivery
or room placement.

Why the electrical setup
matters
The Shasta’s 120V/15A requirement is one of its clearest advantages.
According to Peak, it plugs into a standard household receptacle without
requiring a dedicated circuit. That can simplify placement compared with
larger models.
You should still verify the intended outlet and circuit before
ordering. The sauna draws 1,800 watts, so avoid assuming that any
convenient outlet is suitable—particularly if the circuit also powers a
space heater, treadmill, refrigerator, or other high-draw equipment.
Follow the manufacturer’s manual and consult a licensed electrician when
there is any uncertainty.

sauna electrical requirements guide explains the difference between
standard 15-amp, dedicated 20-amp, and 240-volt installations.
Full-spectrum infrared and
red light
The Shasta uses seven heating panels combining carbon far-infrared
panels with halogen and quartz emitters. Peak lists a maximum operating
temperature of up to 150°F.
An interior full-body red-light panel is included. Peak specifies
eight wavelengths and provides app-based programs, but buyers should
treat these as wellness features rather than medical treatment. 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 Shasta can be controlled through touchscreens inside and outside
the cabin or through Peak’s Wi-Fi app. Remote preheating is useful
because infrared saunas need time to reach the preferred session
temperature.
Other included features include two Bluetooth speakers, chromotherapy
lighting, an oxygen-ionization system, and a foot heater. These do not
replace the fundamentals of heat performance and fit, but they can make
frequent home use feel more polished.
Size and room planning
At 42 inches wide, 40 inches deep, and 75 inches high, the Shasta is
compact for a freestanding cabin but still substantial furniture. The
interior is 38 inches wide by 36 inches deep. Measure the exact room,
ceiling height, door swing, outlet position, and assembly clearance.
Peak describes the Shasta as an indoor sauna. Do not place it in a
garage, outdoor structure, or moisture-prone area unless the
manufacturer confirms that the exact environment is approved.
The one-person capacity is both a benefit and a constraint. It
reduces the footprint, but there is no flexibility for shared sessions.
If two people may regularly use the sauna together, buying a larger
model initially may be more practical than taking turns.
Delivery and assembly
Peak currently includes free curbside delivery within the continental
United States. The sauna arrives by freight in a protective crate, and
the carrier schedules a delivery window. Curbside service does not
include carrying 305 pounds of panels into the home, assembling the
cabin, or removing the crate.
Plan who will move the panels from the curb, how they will travel
through doors and hallways, and how packaging will be discarded. Inspect
the shipment before signing, following Peak’s delivery instructions.
The cabin uses clasp-together panels. Peak states that two adults can
typically complete assembly in 60–90 minutes with minimal tools,
although the product page also describes about two hours in another
summary. Allow extra time for uncrating, checking components,
positioning the panels, and reviewing the manual.
Warranty and ownership
Peak’s written residential warranty lists seven years for heating elements and the cabinetry and wood structure, three years for the control system, power supply and red-light panel, and one year for lighting, sound, accessories and Wi-Fi/app connectivity. It excludes labor and some shipping costs; coverage is non-transferable and subject to the full policy. Peak offers lifetime U.S.-based support, which is separate from parts coverage. Read the current Peak warranty terms before purchasing.
Ongoing care should follow the owner’s manual. Use a towel to protect
the bench, allow the cabin to dry after sessions, and use only
manufacturer-approved cleaning methods. Avoid harsh household chemicals
on the wood or heating components.
Shasta versus Fuji or
Matterhorn
The Shasta is the simplest Peak model to place electrically and the
smallest of the three cabins covered in our comparison. The Fuji seats
two and uses a dedicated 120V/20A circuit. The larger Matterhorn seats
three and requires dedicated 240V/20A service.
Choose the Shasta when one-person capacity and standard-outlet
convenience are priorities. Choose a larger model if shared use matters
enough to justify the increased floor area, electrical preparation, and
price.

Who should buy the Peak
Shasta?
The Shasta makes the most sense if you:
- want a premium indoor sauna for one person;
- need a relatively compact 42-by-40-inch footprint;
- prefer a standard 120V/15A connection;
- value Wi-Fi control and an included red-light panel; and
- have a clear plan for curbside freight delivery and assembly.
It may not be the right choice if you expect shared sessions, need
professional room placement included, have a very tight delivery route,
or want a basic heat-only sauna at a lower price.
Final thoughts
The Peak Shasta’s strongest selling point is practical: it offers a
full-featured one-person cabin without the electrical preparation
required by many larger saunas. Its compact footprint, app control,
included red-light panel, and warranty make it appealing for a dedicated
user with sufficient indoor space.
The tradeoff is that $6,950 buys exactly one seat. Measure carefully,
verify the circuit, review the written warranty, and make a realistic
freight-delivery plan before ordering.
