Integral Floor
INSTALLATION OF SAUNA ROOM
All wall panels will be numbered at the top and should be visible from the
interior of the room. These numbers will coincide with the numbers on
the base frame. NOTE: The tongue and groove on the panels will always
face the same direction
•EACH PANEL IS HEAVY.USE CAUTION TO AVOID INJURY WHEN INSTALLING,
ESPECIALLY THE ROOF PANELS.
•TWO ADULTS ARE REQUIRED FOR THE INSTALLATION OF SAUNA ROOM.
Base Installation
1. Position the base frame or Integral floor in the desired location on
a level surface. The largest number on the base frame is the
standard door location. The stamped numbers on the base frame
should be readable from inside of the room.
a. Standard base (rooms larger than 5x7): Fasten the corners
of the base frame using one 3” screw at each corner in the
predrilled holes. Predrilled holes are purposely made at an
angle.
b. Integral Floor (rooms less than 5x7): The base frame will be
built into the integral floor.
2. The base rail is numbered to correspond with the panels. Number
1 should be to the right of the door, couting up as you move
counter clockwise around the base.
3. Using a level and measuring tape, confirm the base frame is square
by measuring corner to corner. The dimensions should be the
same when the base is square. Shim where needed to level the
base.
Wall Panel Installation
4. Starting in a corner place the panel on the outer edge of the
corresponding floor panel. Slide the panel along the base frame
until framework is flush with the outside of the base frame.
NOTE: To help prevent rain, snow, and moisture, use silicone caulk
in between the base rail and walls as well as in between wall panel.
5. Hold the first panel in place and carefully lower the perpendicular
side wall corner panel into the base, starting at an angle and sliding
it into place. Slide it tight into the corner so framework is tight up
against the framework of the other panel.

71-0156 Page 6 4215-136
Rev. 03 10/21/2022
NOTE: The 4x6,5x6, 6x12 rooms have a one-piece side wall system,
and the 4x5, 5x7, 7x10 rooms have a two-piece side wall system.
The process is the same for the one or two-piece systems.
NOTE: For ease of installing the panels, tilt the top of each panel
back to get the tongue and groove alignment started. Then tilt
forward for an easy fit.
6. Secure the 2 corner wall panels with three 3” Torq screws
(provided). Install one screw on the top of the wall, one in the
middle, and one on the bottom. Ensure the tongue and groove
wall boards are tight together at the interior corner of the sauna
and the corner is flush on the outside edge when screws are
installed.
7. Ensure that the two corner wall panels are flush for the entire
length (base to top) and locate the pre-drilled holes and use the
supplied 3” screws to secure the two panels together.
8. Continue to install each wall panel with the corresponding base
number staring from your initial corner and working around the
room.
9. Make sure that the wall panels are flush at the top and seated into
place at the bottom. Ensure the tongue and groove are fully
engaged between each panel.
10. First ensure tongue and groove are fully engaged. Then secure the
2 back wall panels together with a 3” screw where the panels meet
on top.
11. Continue installing the next panel in the number series, being
careful not to damage the tongue & groove pieces of the panels.
Remember to angle the wall panels and then slide them into place
so that the length of the tongue is seated firmly and evenly into
the groove.
NOTE: A rubber mallet or wood block and standard hammer can
be used to make sure that the bottoms of each panel are even
with the corners of the base frame/floor perimeter. Be careful not
to damage the panels when using this technique.

Rev. 03 10/21/2022
12. Secure the side wall to the back wall panel with (3) 3” Torq screws.
Install one screw on the top of the wall, one in the middle, and one
on the bottom.
13. Install the remaining wall panel up to the door panel. You will
install the door panel next to the right front wall panel before you
install the final wall panel.
14. Secure left front wall panel to the left side
wall with three 3” Torq screws. Ensure the
tongue and groove are tight at the interior
corner when screws are installed.
Top Plate Installation
15. After installing the wall panels, install the 1” top plate. This top
plate aligns and locks the top of the wall panels together.
Note: Before installing top plates, ensure all panels are fully
connected on top and on the corners.
16. Install back top plate first. Matching top plate
with the corresponding wall panels number.
Install notched ends facing up.
17. Install the left and right wall top plates notched end facing down.
So, they fit into the notches of the corresponding top plate.
18. Firmly press down (use a hammer if needed) until top plates rest
on the framework of the wall panels.
19. The top of the plate should be flush with the top of the interior
tongue and groove.
20. Secure top plates using the 2” Torque screws. Install one screw in
each corner and one screw in the center of each wall.
21. Install ½” self-adhesive foam weather stripping on
the top plates. Adhesive side down to the top plate.
22. Install corner caps to each corresponding wall panel
make sure corner cap is flush with base of wall.
Secure using Brad nails or finishing nails (not
supplied),

Rev. 03 10/21/2022
*Defer to heater manual for specific instructions.
60. A licensed electrician should wire the heater according to the
specifications provided with the heater. One of the wall panels has
a removable board to allow for wiring access to the heater. This
tongue and groove board is in the trim package. After the wiring,
attach the board with the brad nailer.
Wiring
*Defer to heater manual for specific instructions.
61. Depending on your heater and control selection for the sauna, you
may or may not need a low voltage connection box for the lights.
When using a SaunaLogic2 control, the lights are hooked up inside
the regular contactor box. Other heaters such as the Designer,
Vena and others may need this low voltage box for lighting hook-
up.
Rock Placement (Very Important)
*Defer to heater manual for specific instructions.
62. Rinse the rocks before placement in the sauna heater. Place the
smaller and flatter rocks around the outside of the rock
compartment and the larger rocks in the center. This allows good
air transfer through the heater. Do not try to force all the rocks in,
it is important to have space between the rocks.
Duck Board
63. Place duckboard (floorboard) on floor in front of the lower bench.

WARNING!
The exterior of your Euro outdoor sauna requires prime & paint or stain within a few days
of installation, and before being exposed to rain or snow. DO NOT paint or stain the
interior. See page 3 for recommendations.
COMMONLY ASKED QUESTIONS
CLEANING
It is a good practice to always place a clean towel on the seating surfaces during sauna use and wipe
surfaces dry when done bathing. However, perspiration and dirt may absorb into the wood, so
periodic cleaning is needed. Scrubbing the benches and floorboards with a stiff brush and mild
detergent is normally sufficient. For heavily soiled or stained wood, a light sanding with 220 grit
sandpaper is another option.
Light cleaning and dusting with a damp microfiber cloth can be used on all surfaces.
STAINING OR PAINTING THE INTERIOR
You should never use stains or paints on the interior of a sauna! These products will off-gas during
the heating cycle and could be harmful to your health.
The only approved product to use on the interior of your sauna is 100% pure paraffin oil. Available
from your dealer or Sauna360, pure paraffin oil will add a breathable, colorless, and odorless layer
of protection against moisture absorption on the wood surfaces. Depending on use, the protection
can last several months or longer before re-application is needed. (Note: use of Paraffin oil on soft
woods like cedar may darken the color of the wood)
STAINING OR PAINTING THE EXTERIOR
All outdoor sauna’s must be protected from the elements as soon as the sauna is built! Reference
your installation guide or contact Sauna360 for a list of recommended products. Failure to protect
the sauna can result in damage to the exterior of the sauna and may void your warranty.
REPAIRING NAIL HOLES AND CRACKS
Any decent quality wood filler that matches your wood species can be
used to fill any small nail holes or even smaller cracks. Apply filler,
allow to dry then use a 220-grit sandpaper to smooth the surface.
