I made this because drawing benches by hand is slow, and every time the room changes you draw them again. Here you pick a few options, click a wall, and change the numbers until the bench fits.

• Straight or L-shaped, with 2 or 3 levels. On an L you choose which levels turn the corner, so the lower ones can run straight and leave a bay for the heater.
• A wooden railing round that heater bay, if you want one.
• A backrest of slats on battens fixed to the wall above the top seat.
• Real boards. Board width, thickness and gaps, frame sizes, bearer spacing and stock length are all settings. The defaults are 20 mm (3/4") boards with bearers no more than 900 mm (35") apart.
• A cut list of every board and bearer, which you can copy to the clipboard and paste into a spreadsheet.
• Warnings when something doesn't work: boards longer than your stock, less than 1 m (3' 3") between the top seat and the ceiling, or a bench in front of a window.

It works in any room you model in Blender. If you use our Cabin Machine add-on, the bench joins the building and uses the same sauna wood.

1. Download the zip. Don't unzip it.
2. In Blender, open Edit › Preferences › Get Extensions.
3. Click the ▾ menu at the top right and choose Install from Disk. Pick the zip.
4. In the 3D viewport, press N and open the Sauna Benches tab.

Then click Add Sauna Bench and click a wall inside the room. Press Esc or right-click to stop.

This is a design aid, not a structural check. The default sizes are what I'd start a drawing with, not engineered numbers. Check the board spans and the frame with your timber supplier or an engineer, especially for long benches or thinner boards.

Sizes assume the Blender scene's Unit Scale is 1. The panel warns you if it isn't.

This is version 1.0. If something breaks or there's a bench it can't draw, tell me and I'll look at it.
