8’x12′ sauna plans reviewed while sitting on the sauna bench

Two Bench options for your 6’x8′ sauna hot room:

8x12 sauna plans

Either option can work ideally within your 8’x12′ sauna building.

Advantages of Option A:

  • A longer set of benches: (7’4″ long vs. 6′ long in option B).  Great for laying out and generous space for 3 on upper bench.
  • A more congenial connection to changing room (especially with candle window).

Advantages of Option B:

  • Stadium seating allows for continued vista from hot room outside through transom window to outside.
  • Plenty of room on lower bench.  A fully extended 24″ lower bench, vs a tighter fitting lower bench in option A.
  • Stove is safely tucked in its upright and locked position in the corner, vs. having to pass by the stove to enter/exit in option A.

I have built a few saunas with each bench design.

Like orange juice with pulp or without, preference varies.  But this isn’t an opportunity for line extension, more shelf space, and choices to drive you crazy.  This is an opportunity to make a decision on what’s best for you… and go for it.

Either option works great.

  1. when deciding on a bench/stove layout, keep in mind the recommendations of the stove manufacturer for stove clearances to both combustible and non-combustible surfaces. option a is very difficult to achieve decent bench depth while also maintaining the stove manufacturer’s clearance recommendations. it is always a good idea to follow the manufacturer’s recommendations but if you are going the building permit route, the building inspector is all but going to demand the clearances be followed. this is an excellent reason to select your stove first and plan the sauna around it!

  2. A water tank attached to an authentic wood burning sauna stove takes up 6″ or so of space but buffers ones’ toes from the burn and ouch, and provides warm water for the OUTSIDE sauna bather on a zero degree star filled January night, steam billowing, and ahhhhhh damn, does that feel good.

  3. Hi Glenn!

    I just purchased your build your own sauna book a few days ago and I can’t get it out of my brain! I’ve literally woken up every night this week thinking about sauna design. Your book has been extremely helpful. A few questions, though, I’m hoping you can help answer for me.

    1. I love your 12×8 design, but would really like two levels both on the back wall and the side opposite the stove. Do you think expanding the design to 12×9 will make enough room to add a second level bench on the side wall opposite the stove? Any reason to talk me out of this?

    2. I’m reading the specs for your recommended Kuuma wood stove. It looks like their recommendation is for 11″ clearance from the side wall and 11.5″ for the back wall (assuming use of heat shields AND cement board). Do you use these recommendations or can you get away with putting the stove closer to the wall? Seems like using their recommendation in a 8×6 sauna would only leave about 5 inches between the stove and the bottom bench. Does that sound right?

    3. On page #38 of your ebook you have a broken link to the selkirk website that is supposed to list the chimney part components. Do you have an updated link or list you can send for that?

    Thanks for the help!

  4. Hi Brian:

    1. Instead of 12×9, i’d be thinking dimensionally, like 12×12 or 12×10. I’d try to talk you out of too big of a hot room:

    2. Kuuma clearances: Technically if your wall is all NON combustibles there is no setback requirement. Practically speaking, as we frame with 2x4s, etc. you’ll want 7″ from Kuuma heat shield to cement board with 1″ air gap from cement board to wall behind. This is a great system. Good mass, looks good (you can face it with stone or tile), inexpensive.

    3. Selkirk: thanks for the heads up re: broken link. Here’s more to noodle on:

  5. Hi Glenn,
    On Your answer #2: “Kuuma clearances: Technically if your wall is all combustibles there is no setback requirement.”… Did you mean “non-combustibles”?
    I’m sorting out those same issues right now.
