The best hardware for a sauna door


Authentic sauna enthusiasts are sometimes inconvenienced by folks who keep the sauna door open, or forget to close the door on their way out.  Are these the same people who drive slow in the left lane?  Drivers on the Autobahn in Germany have no patience for this social ignorance.  They’ll get right on your bumper and flash their lights, until you get your shit together and move out of the way.

The flash the high beam equivalent for sauna is this $3.19 spring, available at Home Depot and most hardware stores here in North America.

This simple piece of hardware, one end screwed to the top of your sauna door and the other to the door jam, gives the sauna host an assurance that one of the few sauna rules, -“close the door!” – is being followed.

  • Kids are notorious for not closing the sauna door behind them.
  • Low bench Larry’s are often so preoccupied with overheating, that they too forget to close the sauna door behind them.
  • New visitors to sauna are often so saturated with the nuances of the new experience that closing the sauna door is often down their list of things to remember.

BONUS:  This ball catch can work in conjunction with your Prime-Line Screen and Storm Door Spring – same isle.

  1. I don’t know Glenn. The screen door spring seems such a crude solution to the problem of the sauna door.

    Yes, you’ve stemmed the draft and loss of heat, but with a sharp slam from the door hitting the jamb under the tension of the spring? And for all users, even those who know better. I don’t think that this is the solution.

    I’d personally approach this with more subtlety, perhaps hanging a nicely embroidered sign that says “Sulje hiton ovi”.

  2. I’ve had good luck with these springs. I installed one at my cabin sauna, and the door closes with a soft tap. I just installed two here in Minneapolis – one for the OH sauna and one for my backyard sauna. At first the door banged a bit, but this spring has a nice feature: close tension can be adjusted from one end (vs redrilling the hook) to provide, as New Order says, The Perfect Kiss.

    Because the spring has an inner spring opposite to the outer spring, the door actually closes more softly now vs. the manual treatment from some of the amateur brute fringe members of Twin City Sauna Club.

    Come try it out!

    $3.19 at Home Depot, but if you’re working on nicely embroidered signs, can you make one that says:

    “throw your empties in the garbage” ?

  3. Installed a similiar spring with wool felt weatherstripping around the door frame to make a nice seal and hush the slam. Money well spent ! with two kids and the a few low bench friends.

  4. \I like the closures, simple is best, what kind of handle did you put on this door?\

    Rick from Prime-Line here.

    First off, thanks for the mention Glenn. TR2, we sell a kit that has the spring, hinges, handle, and a door latch you can install inside the door for privacy. (Click my name to see product)

    I would think that a handle like included in the kit would work fine. Or you could pick out a fancy knob at your local hardware store. It doesn’t take a whole lot of force to open a door like in the photo.

  5. I am not in the favor of these sauna spring doors. If you have children in your home, then i will suggest you to not to install these doors in your home as children may get harmed while playing.

  6. Dear stable gate…
    I think your children should wear helmets. My spring works just fine. Thanks for your concern.

  7. Hi Glenn. Just purchased your e-book and looking forward to perusing the building tips. I’ve been a “lurker” on this site for awhile. We are in the process of building an outdoor sauna and have just completed the site and foundation. I found the excellent information here you posted on windows for an outdoor sauna but nothing on door selection. Do you have any suggestions for a good sauna door? Definitely want to have a window in the door.

  8. Hi Kim: in the ebook, there are step by step instructions on how to build a really good hot room sauna door. Custom sauna doors are the way to go for a bunch of reasons, one of which is that the recommended door size is 24″x6’4″ or so, a size nobody makes.
