Imagine stepping into your newly built sauna, only to find that the bench feels wobbly or, worse, starts creaking under your weight. You might wonder if the installation was done correctly. One crucial aspect often overlooked in sauna construction is the proper installation of bench screws. Installing the screws from the underside not only ensures a sturdy bench but also enhances safety and aesthetics. In this article, you’ll learn the reasons behind this practice and how to do it effectively.

These #10-24 x 2″ stainless flat head screws are designed for easy installation and provide a universal fit for various shower stools.

Why Choose Underside Installation?
Installing sauna bench screws from the underside offers several significant advantages:
- Safety: Properly installed screws prevent benches from wobbling. A secure bench minimizes the risk of injury, particularly in a humid environment where slips may occur.
- Durability: Exposed screws can corrode over time due to moisture. Installing them from underneath protects them from direct exposure to water and steam.
- Aesthetics: Underside installation leaves a clean surface on the bench. This feature enhances the overall look of your sauna, making it more inviting.
Choosing the Right Screws
Choosing the right screws is fundamental for the longevity and safety of your sauna bench. Consider the following:
- Material: Stainless steel is the best option due to its resistance to rust and corrosion. It holds up well in a sauna environment.
- Size: A #10-24 x 2″ screw is typically sufficient for most bench installations.
- Head Type: Flat head screws provide a flush finish, preventing snagging and making cleaning easier.
How to Install Sauna Bench Screws from the Underside
Follow these steps to install your sauna bench screws correctly:
- Gather Materials: You’ll need screws, a drill, a screwdriver, and a measuring tape.
- Measure and Mark: Determine the locations for your screws on the bench supports. Ensure they are evenly spaced to provide maximum stability.
- Pre-drill Holes: Use a drill bit slightly smaller than your screws to create pilot holes. This step prevents splitting the wood.
- Attach the Bench: Position the bench on the supports, ensuring it’s level. Insert screws from the underside, tightening them securely.
- Check Stability: After installing, test the bench for stability. It should feel solid with no wobble.
Pro tip: Always use a level when positioning your bench. This detail ensures optimal comfort during use.
Installation Comparison Table
| Installation Method | Pros | Cons |

What is the best screw type for sauna benches?
Stainless steel screws are the best choice. They resist corrosion and offer the strength needed for supporting weight in a humid environment.
How often should I check the screws?
Check the screws every few months, especially after heavy use or if you notice any wobbling. Regular maintenance can prevent larger issues.
Can I use regular wood screws?
It’s not advisable. Regular wood screws may rust or corrode in a sauna environment. Always opt for stainless steel or screws specifically designed for wet conditions.
Do I need special tools for installation?
No special tools are necessary. A standard drill and screwdriver will suffice. However, using a level will help ensure proper installation.
What if my bench is already installed?
If your bench is already installed, you can still access the underside to tighten screws. If they are loose, consider adding additional screws for better support.
