What's required of me to start?

Not much. You’re likely still in the sauna planning phase

Our 12×12 SMP fits your existing 12×12×7 room

For now, we just want to make you aware of these phases and skills for it all to come together

Measurements and Joist Direction

Measuring walls (#1-5) and ceiling joist direction is NOT required to begin your quote or order. Once you’ve built walls #1-5 or you have a plan, send us dimensions and indicate ceiling direction (See Wall TAB in Step 4)

NOTE: Before installation, walls must be framed at ~12×12 ft with a ~7 ft ceiling and a 24×82″ door R.O. (see options). Heater appliances work best with in/exit wall vents!

Electrical Preparation

Your electician will run wire for the sauna heater, light and switch through studs and return later to connect them after you’ve insulated the walls, tacked up the sauna foil vapor barrier and covered the walls in cedar paneling. A 12×12 sauna room uses: 14 kW heater / 240V / 80 amp breaker / 8 gauge wire

Light Carpentry Skills to Build a Sauna

T&G (Tongue & Groove) boards require field trimming to affix to the ceiling and walls. Install the pre-built benches, guard rail, flooring (optional) and trim to cover all seams. Please watch our Sauna Kit Construction Video Series

See our complete prep list before sauna installation (if Cedarbrook installs your sauna)

What are the contruction steps involved?

You have an existing 12×12×7 room OR you’ll frame one in

PREPARATION AND CONSTRUCTION: VARIES 3-8 WEEKS

Main Steps to Constructing a Sauna Room using our Sauna Materials Package
Watch our Install a Sauna Materials Package in New Construction Video

Structural Preparation

  • Construct studs and joists for a 7′ ceiling, typically. If you have existing drywall, NO need to remove it (if walls are insulated)
  • Frame a 24×82″ R.O. (Rough Opening) for your door
  • Add blocking for the vents (4×6″ common). In small indoor saunas you can use a <1″ gap under the door as an intake vent

Electrical Preparation

  • Review the electrical capacity of your service panel for available Amps A 12×12 sauna room uses: 14 kW heater / 240V / 80 amp breaker / 8 gauge wire
  • Run electrical wire planning for the heater, lights, switch and external controls (optional)

Build Your 12×12 Cedar Sauna!

  • Insulate the walls with formaldehyde-free batting (source locally)
  • Staple sauna foil vapor barrier (provided) to the joists & studs — Do NOT skip!
  • Trim and nail your cedar paneling to the ceiling first, then the walls
  • Start first T&G row near the floor. Go round the room. Check corner seams line up
  • Install sauna door (you can order a custom jamb)
  • Install the sauna benches and add the facing (optional)
  • Nail corner seams and trim the door
  • Build the duckboard flooring (optional) in removable sections

Power Up!

  • Hang heater on the wall (if wall-mounted type)
  • Next, your electrician will return to connect the heater, controls, sensor, light/s and switch, etc.
  • Make sure they test your heater!
  • Load your heater with rocks loosely for best air flow and take a sauna! Enjoy and send us pictures

  • Actual build site. Will your sauna go in the basement or over a bridge, then onto a goat trail? Please tell us what conditions to expect in your email or your notes
  • Work Flow. Your site condition may restrict where we can actually make wood cuts. If we must walk more than 20 feet to cut outside, then it will add to the time and cost

    GENERIC FLOOR PLAN

    Below is our GENERIC FLOOR PLAN

    We create a custom floor plan (and an elevation plan for outdoors kits) after you make a deposit

    In the steps below, you can affect your FLOOR PLAN and ELEVATION plan. Before we actually build your sauna, we ask for your approval of any plans uploaded to your MyAccount area

    • Sauna Plan — Our plans cover most sauna layouts
    • Heater — We show the popular ones or substitute another or procure your own
    • Door — 3 basic styles or substitute a custom one or none (if an SMP)
    • Explore options for Flooring, Benching, Seat Width, Lights and Windows etc
    • IF OUTDOORS: Roof type, overhang, waterproofing material and color

    NOTE: The DOOR SWING shown in these plans is just the typical one. You'll choose your swing (and other options) when you select your door style, height, etc.

    Sauna Plan Diagram: 8X8GPC-SQCRB4

    Sauna Footprint: 12′ 8″ × 12′ 8″

    Sauna Footprint for our Sauna Kits

    In our 12 × 12 Sauna Kits, the USEABLE INTERIOR floor space is exactly 12 × 12
    EXTERIOR DIMENSIONS: 12′ 8″ × 12′ 8″
    See ALL measurements and details in the "Kit Specifications" button (at right)

    QUESTION: Also we're sometimes asked ... What size should my base or floor tray be for our OUTDOOR SAUNA KITS, so rain water sheds OFF of ALL sides of the sauna?

    ANSWER: You should build your base at: 12′ 63/4″ × 12′ 63/4″. Our 1x8x3/4″ beveled cedar siding will extend just beyond this dimension, so water sheds nicely away!

    [ NOT TO SCALE / 6x8 PLAN SHOWN HERE ]

    FLOOR PLAN ELEMENTS

    Wall Panels #1 –

    Wall Panels #1 –

    Pre-built wall and ceiling panels are HIGHLY insulated (4″thick / R-20)

    Made of 100% Western Red Cedar — even the frame!
    NO glues or plywood are EVER used

    Red lines shown are wall panel seams. Each wall panel weighs 100-150 lbs. with a default height of 6′4″. If your sauna is a Trumpkin design (8′4″ ceiling height), then much heavier, 175-200 lbs.

    Refer to the wall panels numbers #1- when placing items during the sauna design step or if adding a note so we know exactly where you'd like an item

    For example if adding a window (later), pick the wall panel number. See below Step 4 > Windows. You can move lights, vents, switch, controls, etc as needed too by indicating in the final notes box (above the Add to Cart button)

    Walls: 1 – 5 + Joists

    Walls: #1 – 5 + Joist Direction

    To send you correct T&G cedar board lengths ...
    • Measure walls #1-5 (or estimate if NOT yet built) and
    • Indicate your Ceiling Joist Direction in Step #4 > Walls
    RE: Ceiling Joist Direction

    IF your sauna is SQUARE (W=L), then your ceiling panel board can only be one length, but if your room is a RECTANGLE then it's IMPORTANT to know your ceiling joist direction. OR if you don't like your curent ceiling direction, you can change it in Step 4 > Walls > Joist Direction

    RE: Drywall and Windows
    • DRYWALL — IF you already have drywall up, there's NO NEED to REMOVE it. IF your walls are insulated, venting is available and you can run wiring, you're good. If not, there's some planning to do
    • WINDOWS — Add them below in Step 4 > Windows

    Benches: A – D

    Sauna Benching

    Our sauna benches are made of 100% Western Red Cedar with NO VISIBLE fasteners

    This 12x12′ Sauna Material Package includes 4 sauna benches with NO KNOTS

    • Benches are fixed OR optionally slide out of the way
    • Our standard bench WIDTH is 18″
    • Standard bench HEIGHT is 20″ (LOW) and 40″ (HIGH)
    • Facing (or skirting) and back rests are optional
    • Our 4 bench plans include one 22″ wide HIGH bench

    All sauna bench features can be adjusted in Step 4

    NOTE: We NEVER cut sauna benches to custom lengths — This should ALWAYS be done on site, as your measurements may change slightly. They're built in foot increments only

    Need more head room? You can change your door and ceiling height in Step 2 > Choose Your Sauna Door

    Benches: A – D

    Sauna Benching

    Our sauna benches are made of clear 100% Western Red Cedar with NO VISIBLE fasteners

    • Our standard bench WIDTH is 18″
    • Standard bench HEIGHT is 18″ (LOW) and 36″ (HIGH)

    All these features can be adjusted in Step 4

    Need more head room? You can change your door and ceiling height in Step 2 > Choose Your Sauna Door

    14 kW Heater

    14kW Sauna Heater

    A 14 kW heater is included with our 12x12′ Modular Sauna Kits / Volume = 1008 cu. ft. (with default 6′4″ ceiling height)
    • Upgrade your heater or choose NO heater IF you have one
    • We add blocking in the walls to hang wall-mounted heaters, extra for HUUM DROP heaters
    • Heaters can be rotated (90°) to an adjacent wall, IF 2 ft is available

    Some notch their benches to create more room. Benches can also be recessed. We've seen many creative sauna plans over the decades since we started (1971)

    14 kW Heater

    14kW Sauna Heater

    A 14 kW heater is included with our 12x12′ Sauna Material Packages / Volume = 1008 cu. ft. (with default 7′0″ ceiling height)
    • Upgrade your heater or choose NO heater IF you have one
    • Add blocking in the walls to hang wall-mounted heaters
    • Heaters can be rotated (90°) to an adjacent wall, IF 2 ft is available

    Some notch their benches to create more room. Benches can also be recessed. We've seen many creative sauna plans over the decades since we started (1971)

    NOTE: Wall-mounted heaters are VERY HOT at the top third. The middle is warm and the bottom of the shroud body is actually cool. Our LOW benches seat tops are 18-20″ off the floor, so you can place benches closer to wall-mounted heaters at these heights

    Door Swing

    Sauna Door Swing

    Rail & Stile Door + 16x67″ Glass is included in our 12x12′ sauna

    Sauna doors ALWAYS open out as a safety precaution

    The door swing shown is our suggestion. It's a bit easier when reaching for the built-in heater controls to prop the door open with your backside

    Set your door swing when choosing your door in Step 2

    NOTE: Doors come with one handle as they're self-closing. Mount the handle on the outside of the door

    Flooring

    Optional Duckboard Flooring

    We offer a grating to cover your hard floor

    See Step 4 > Flooring. Choices are None, Walking Area Only or the Entire Floor

    Installing Duckboard flooring is the LAST step when building a sauna
    Purpose of Duckboard:
    • Duckboard is removable, so you can easily clean!!
    • Warms to the bare foot
    • Conceals an ugly floor / see cedar everywhere
    • We provide the materials. Assembly required

    Vents

    Sauna Venting

    Vents ensure adequate fresh cool air enters the sauna and some hot air exits

    You can move the vents as needed per your site condition. Hot air (that's exiting) should be vented into any adjacent room or an attic, sometimes outside is the only option, but NEVER into a wall cavity. Also, NOT that much heat actually leaves the sauna

    Can I vent under the door?

    Yes! In smaller sauna rooms (<4x6) it's fine to use a < 1″ gap under the door without a dedicated INTAKE vent

    In larger saunas (>4x6), venting ONLY under the door will put a strain on the sauna heater appliance. Heaters are designed for cold air to easily pass through the rocks and over the elements heating the sauna room. It breathes better and so will you!

    Vent Size Rule:
    • If heater < 9kW, use 4x6″ vents
    • If heater ≥ 9kW, use 6x8″ vents

    Vents

    Sauna Venting

    Vents ensure adequate fresh cool air enters the sauna and some hot air exits

    We can move the vents as needed per your site condition, let us know in the notes above the Add to Cart button. Hot air (that's exiting) should be vented into any adjacent room. Also, NOT that much heat actually leaves the sauna

    Vent Size Rule:
    • If heater < 9kW, use 4x6″ vents
    • If heater ≥ 9kW, use 6x8″ vents

    Light / Switch / Control

    Lights / Switch / Controls

    Move these items as needed per your site condition

    Just refer to the Wall number #1-5 and/or Bench letter (A, B, C, etc.) in the final notes box (above the Add to Cart button)

    • LIGHTING — One light is included in the Accessories Bundle

      Generally, we place the light on an open wall OR above a LOW bench but NOT above the sauna heater. Note, you can add lights under the benches too. See Step 4 > Lights

    • SWITCH — Usually best placed on the open side of the door (if there's space)
    • EXTERNAL CONTROLS — Our generic sauna plans show a heater with built-in controls. If you upgrade your heater, we'll place these controls next to the switch or specify where

    Of course, when you actually install these items, do what you want. This is just for our Sauna Plan drawing and so we're both on the same page when discussing your sauna

    • EXTERNAL CONTROLS — Our generic sauna plans show a heater with built-in controls. If you upgrade your heater, we'll place these controls next to the switch or specify where

    Add a Changing Room

    Add a Changing Room

    Changing Rooms can only be added to 4x6′ and larger saunas. The Changing Room wall's smallest dimension will be 4 feet

    It's best connect the sauna to the changing room, it works best usually to place your "SAUNA DOOR" on the SHORT Wall

    Later, the "DOOR for the CHANGING ROOM" will go:
    • On a LONG WALL with a SLOPED ROOF, or
    • On the SHORT WALL with a PEAKED ROOF

    To add the changing room, SEE the MAIN MENU: SAUNAS > CHANGING ROOMS

    ADA Compliant Sauna

    An ADA-Compliant Sauna Requires

    ADA-compliant means your sauna meets the requirements to ensure those needing wheel chair access have the necessary room to maneuver

    • A 5x5′ turning radius — Thus a 7x7′ sauna with 2 benches is basically the minimum size available
    • A 36″ wide door — We'll build your door choice at 38x72″, 38x76″ or 38x82″ RO. So, choose "Browse other doors", then add a COMMERCIAL-sized door to your shopping cart
    • ADA threshold — A 5/8″ max threshold is allowed
    • Flooring — Many add Dri-Dek Sauna Rubber Flooring for better maneuvering

    RO = Rough Opening T&G = Tongue and Groove. This is the cedar panel cladding covering both sides of the door

    Ceiling Height

    Ceiling Height = Headroom

    Figure below is the actual headroom! The ceiling panels will add 4 INCHES. IF this is an OUTDOOR sauna kit, the roof adds ~ 2 FEET additional.

    Saunas heat from the TOP DOWN. For most residential saunas, ceiling joists should be built at roughly 7′0″.  Also know, that MOST residential sauna heaters are rated for ceilings 8 ft and lower.

    Of course, you'll sweat just as well or better in a lower ceiling too. But metal sheeting fire protection is required if a ceiling < 6′2″ from the sauna floor. Defer to the manufacturer's installation manual in all cases for distance from top of heater to ceiling.

    T&G Material

    T&G Cedar Material Thickness

    T&G = Tongue and Groove – that's the cedar paneling on the walls

    We offer standard 3/4″ material OR IF WxL = 4x4, 4x6, 6x6, 6x8 or 8x8, then you can select 1/2″ material

    FAQ: What's the PROs and CONs of a thinner material?
    THICKNESS 11/16″ vs 7/16″

    PROs of 1/2″ material
    • It looks the same
    • The insulation factor difference is negligible
    • It's saves you some money
    CONs of 1/2″ material
    • It's thinner (7/16″), so it flexes slightly where you lean against the wall
    • Consider adding extra wall blocking at back level height above benches
    • No one will know you saved money

    ❯ Joist Direction

        What to Know about a Glass Front Wall

        Glass front walls add an amazing ambiance to any sauna — Yes!! You're immediately self-invited … just looking at it!! So you're going to take more saunas. That said...
        • YOU MUST UPSIZE YOUR HEATER KW OUTPUT

          Glass is beautiful AND it's also a HEAT SINK / LOSS! ... Every 10 square feet of Glass adds an EXTRA 50 Cu Ft volume of space to heat.
          So 7x7′ wall adds 250 Cu ft to the CC Ft you're already heating for this sauna. 420 cc ft is the max of many 8kW heaters

        • You can't mount a heater to glass, cut it or run wire

          So there's some extra design and planning details … And we're happy to help sort thru them with you

        RE: GLASS / PLEASE READ
        NOTE: IF your FRONT wall is glass top to bottom, then a wall-mounted heater, intake vent, light and switch MUST be on other walls OR ... You can simply set the height of your glass to make a shorter wall! In this way, you could also create a window of any size

        Dimensions

    My walls are NOT built yet... What's the maximum coverage of this 12×12′ package?

    12×12′ SMP's Maximum Coverage?

    FAQ: What's the MAXIMUM stud-to-stud-to-joist measurement that fits this 12x12 Sauna Materials Package?
    Set your wall spans at:
    • WIDTH = 12′15/8″
    • LENGTH = 12′15/8″
    • HEIGHT = 7′ 3/4″ *
    IMPORTANT! When maximizing coverage, note you must leave a 3/4″ gap in all corners (except floor). The trim kit provided will cover all corner gaps!

    * NOTE: 3/4″ is the thickness of our standard cedar material. Decrease wall spans by 1/2″, IF you selected 1/2″ material (this option only available IF WxL = 4x4, 4x6, 6x6, 6x8 or 8x8)

    At these dimensions, the sauna benches will fit perfectly with ~1/8″ on each side* — NO need to trim your benches and cutting the cedar boards is minimal. At these dimensions, sauna benches will drop in at an angle without scratching your cedar walls

    DUCKBOARD FLOORING

    Duckboard is offered as 1x3″ smooth cedar material you'll build to cover on your hard floor

    HOW TO BUILD DUCKBOARD

    We provide the materials per below / Assembly Required

    Duckboard Flooring Materials
    • 1x3″ S4S Tops (actual thickness 11/16″)
    • 1x3″ Sleepers (actual thickness 11/16″)
    Overall height 1 3/8 ″
    Fasten up through the bottom of the sleepers using 1″ crown staples or screws, so NO fasteners are exposed to the feet

    Duckboard

    Duckboard Flooring

    We offer a floor cover or grating called Cedar Duckboard that quickly warms to the foot and conceals your HARD floor*

    Build duckboard with our 1x3″ cedar material in small sections. So it's removeable to clean. NO Flooring means your feet touch your HARD floor

    ► Duckboard is ALWAYS built AFTER installing your benches

    * HARD floor is your cement slab, tile, lineoleum, plywood, etc.

    Regarding vent size: For a 12x12′ sauna, we recommend a 14kW heater (or stronger)

        Vent Size

        Proper Vents

        Reasons you may want a stronger heater:
        • When adding an all-glass front wall
        • Your sauna is outdoors
        • You want more rock capacity (a feature of some heaters)
        Heaters < 9kW use 4x6″ size vents
        Heaters ≥ 9kW use 6x8″ size vents
        • Intake vents are placed behind or near the heater about 2″ above the floor
        • Exit vents are best placed in the opposite corner about 6″ below the ceiling
        • Small saunas (<4x6′) can use a 1/2″ gap under the door as an intake vent
        Pick only the accessories that best complement your sauna tastes. Enjoy!

        Trim Material

        You may not need dedicated trim material for your existing window. Sometimes there's extra cedar flooring material (if you selected duckboard). Of course, there will be some extra material that would have covered your existing window's area. It's difficult to estimate that figure here until more details become available

Real Saunas Contain the Good Heat

The Fins call the good heat "Löyly". In Scandinavia, the sauna is considered a sacred space – a 'church of nature'
At the heart of the experience lies löyly, the spirit or steam released by casting water onto heated stones

How we contain the “Good Heat” / Löyly?

It starts with well-insulated sauna walls: 4″ thick with layers of insulation

  • 1×4″ T&G cedar paneling (11/16″) is the best material to absorb heat
  • Sauna Foil Vapor Barrier (1/64″) provides both reflective and conductive insulation so heat is evenly distributed over the sauna walls and immediately reflected back to the sauna interior
  • Walls are framed with 2×3″ cedar (2½”). Frames are studded 16″ on center
  • Rock wool insulation batting  (mineral-based, not fiberglass) keeps heat from leaking. Note: Barrel saunas have NO INSULATION
  • Tar paper, a water proofing material (1/16″). An indoor sauna, of course does not require that, but it’s worth noting that our indoor modular sauna kits can be relocated outdoors – just add a roof. Our indoor/outdoor kits start exactly the same!
  • Beveled cedar siding (¾”). The tapered exterior siding ensures water drips away from the walls. By the way, this is a similar material to what you find in barrel saunas. And that’s all they use in a barrel sauna to contain the heat.

CONTAIN THE HEAT — Enjoy 170°F – 195°F in about 50 minutes. Our Modular Sauna Kits are the most insulated indoor sauna room kits available.
