Your barrel sauna will include the following:
ELECTRICAL REQUIREMENTS
All electrical wiring must be performed by A QUALIFIED LICENSED ELECTRICIAN. Costs of an
electrician can vary greatly depending on several factors, including your sauna’s distance from your
electrical service box, where you live and cost of materials. We always recommend you get quotes from
two to three different licensed electricians before you begin installation in order to get the best possible
service and price.
Use copper wire with 90C insulation. Do not use aluminum wire to make the connection. Consult with
an electrician so you can determine the requirements for your particular situation. All wiring must
conform to all national, state and local codes and regulations.
For further information and instruction on your heater installation and operation, please consult the
provided heater manual.

LOCATING THE SAUNA
Because the traditional sauna experience involves a heating-cooling-resting regimen, it is important to
plan ahead before installing your sauna. Our method of construction allows you to place your barrel
sauna in a wide variety of settings.
Be sure the surface is firm and level, and can support the weight of the sauna and its users (1,000+ lbs).
A deck or concrete slab is certainly an option, but if your sauna sits directly on the ground, be sure the
cradle supports rest on paver stones or something similar to prevent the cradles from settling into the
ground.
BASIC TOOLS REQUIRE FOR INSTALLATION
These tools are helpful in the assembly of your barrel sauna:
• Cordless drill
• Rubber mallet
• Hammer
• Screwdrivers (Phillips and flathead)
• Utility knife
• Level
• Wrench
BEFORE INSTALLATION
Before beginning assembly, ensure that the installation surface is level. Many garage, basement or deck
floors are sloped for drainage. Aslight slope will not be an issue, but a more pronounced slope will require
shimming to make the sauna level. An uneven installation surface can result in poor-fitting staves
leading to poor sauna function. Also, if the site might receive heavy winds, it is recommended extra
precautions are taken to ensure the door does not blow open. In most situations, this factor will not be a
concern.
Unpack all staves. Identify the drain stave (it will have one or more drainage holes bored into it). This will
be the bottommost and first stave used

FLOOR ASSEMBLY
Step1:
Placing the cradles on the ground, For optimal assembly, it is important that the cradles are parallel to
each other.
Image 1 Image 2
Cradles requirements:
barrel saunas require 2 cradles
Step2:
Fasten the drain stave directly in the center of the cradles using 2 screws so the stave extends over the
end cradles by approximately 4”(5.7) . (For barrel saunas with more than two cradles, space the
remaining cradle(s) evenly between the two end cradles. Secure the staves into these cradles as well.)

Make sure the stave sits perpendicular to the cradles of the middle before continuing.
Continue adding staves to each side of the center stave, tapping each into place with a rubber mallet (11).
As you are adding staves, fasten every other stave to each cradle making sure each notch lines up with
the others (12)and that each stave is perpendicular to the cradle.And fix them with screws.

Step3:
Take the three front end pieces, including the door and two side pieces, and line them up so that both
left and right pieces are align with the middle pieces. Gently position the two wing sections into place
on either side of the door panel - you may use a rubber mallet to achieve a snug fit. Secure the wings
to the door section with screws through the predrilled holes on the horizontal support beam.
Step4:
Position the front and half back ends in the notches, with the horizontal support boards facing the inside
of the sauna.
Note: the metal vents are to be on the bottom on the back end, and the vent holes are to be on the top
on the door end (21).
Place a level on the uppermost horizontal support boards on the front and half back ends to ensure
each end is level (22.23). Adjust as necessary. Image (21) shows what your assembly should look like
at this point of the installation process.

ROOM ASSEMBLY continued.......
With the front and half back pieces level and placed, begin placing staves up the sides of the sauna.
Tap each board with a rubber mallet (24).
Hammer a nail through every second or third stave into the front and back end panels to keep them
from falling out (25). The fewer nails you use, the easier disassembly will be should you ever need to
take down the sauna. When stave arrived to the half back piece,then put the half moon window upper
on the half back pieces groove.
You will find it helpful to place a temporary stave at the top, connecting the two ends(27-30). This will
align and stabilize the two ends while you continue adding staves to your sauna.(Please noted that the
slots at both end are different,one side connect the front piece is wide and the other side connect the
glass are narrow)(28)
►Please pay attention to slots between the half-glass and half-back piece.(31)
Note: If you have access to a pneumatic nailer this process will go faster.

BENCHES AND SUPPORTS
Note: You may choose to install benches and supports after the entire room has been assembled, but you
may find installation easier with the space and light afforded at this point.
Each barrel sauna includes two pre-assembled benches that are side specific. Lay the benches on the
lower cleats, which are mounted on each end panel (33).
Fasten the benches into the cleats using the predrilled holes （34). Be sure to countersink the fasteners
slightly below the surface of the wood. For 6’ and larger barrel saunas, position the provided center
support so that it connects the bench to the floor of the barrel. Secure using screws through the
pre-drilled holes. (35)

ROOM ASSEMBLY…CONTINUED
All the sauna room are finished the assemble test before package.So just keep to tap the staves to the top
of the sauna room according to the Number we remarked.
Finally you find that there is a difference in the size of the remaining space between staves, and the
radius produced by the staves will actually be slightly larger than the radius of the barrel end plate (40).
Now you just "lift" the front panel and the rear panel to form an angle, then tap them down with a soft
hammer.This will ensure the tightest possible seal when the strap is tightened.

verify the bands are evenly spaced and align or stagger the bracket placement along the side of the
sauna according to personal preference. Tighten nuts evenly . (46-48).

FINAL THINGS
Once assembly is complete, sweep and vacuum the inside of the sauna. Wipe down the entire interior
with a damp cloth to remove any
remaining dirt, dust and debris.
Note: If the sauna has absorbed moisture in storage, the staves may shrink as the high heat
evaporates that moisture. This may require you to tighten the bands even further. If your sauna is left
in the open rain, this wall cause the staves to expand again resulting in an even tighter seal.
HEATER - Please see heater manual.
Power cord for electric heater is not included and user must buy it at local plumbing and electrical store
or online.
Installer is requires to drill a hole on sauna room wall to connect power cord to wall outlet located
outside the sauna room.
