Sauna benches are the heart and soul of every sauna experience. They provide not just physical support but also shape the way you enjoy heat, socialize, and relax in your sauna. Understanding how sauna benches are made, what designs are best, and how to select or build the perfect bench helps you achieve true sauna bliss. Let’s dive into everything you need to know about sauna benches to make your sauna space comfortable and practical.


What Is a Sauna Bench and Why Is It Important?

A sauna bench is a specially designed seat or platform inside a sauna where people sit or lie down to enjoy the heat. Sauna benches are essential for:

  • Comfort while sitting or laying in the heat.
  • Proper air circulation, allowing the heat to envelop your body evenly.
  • Creating social spaces for group sessions or quiet moments alone.

Benches aren’t just simple wooden planks. Their height, material, placement, and construction all influence your comfort and experience. Let’s break down how to choose or build the right sauna bench for your needs.


Key Types of Sauna Benches

When it comes to sauna benches, there’s no one-size-fits-all solution. Benches must suit the sauna’s size, users’ preferences, and heating method. Here are the main types:

1. Tiered Benches

  • Lower Bench: Closer to the floor, cooler air, good for children or those new to saunas.
  • Upper Bench: Closer to the ceiling, hottest spot in the sauna, great for heat lovers.

Most saunas have at least two levels, making it easy to change your sauna experience by just moving to a different bench.

2. Floating (Suspended) Benches

  • Attached to the wall for a sleek, modern look.
  • No supporting legs, which makes cleaning underneath a breeze.

3. Freestanding Benches

  • Entirely independent structures.
  • Can be moved or replaced as needed.
  • Ideal for portable saunas or where flexibility is important.

4. Custom-Designed Benches

  • Tailored to fit unique sauna spaces (rounded corners, L-shapes, wrap-around).
  • Special dimensions for accessibility or personal taste.

Key Considerations Before Choosing or Building Sauna Benches

Planning out your sauna bench is crucial for comfort, safety, and lasting enjoyment.

1. Materials Matter

Picking the right wood is essential. The best sauna woods are:

  • Cedar: Naturally resists moisture, rot, and scents wonderful in heat.
  • Aspen: Light in color and keeps cool to the touch.
  • Hemlock: Durable and less likely to splinter.
  • Spruce or Alder: Budget-friendly and workable.

Avoid using woods like oak or pine, as they can ooze sap, get too hot, or warp over time.

2. Bench Dimensions

Most sauna benches adhere to these practical guidelines:

  • Height: Lower bench 16-18 inches; upper bench 36-40 inches from the floor.
  • Depth: 18-24 inches deep for comfortable sitting or reclining.
  • Spacing: 1/2 inch – 3/4 inch gaps between slats for airflow and drainage.

3. Ergonomics

  • Rounded edges for comfort.
  • Slightly angled backrests for relaxation.
  • Sufficient clearance for legs and movement.

4. Weight Support

A well-built bench should easily support adult weight.

  • Use sturdy lumber (2×2, 2×4, or thicker for support rails).
  • Cross bracing keeps benches from wobbling or sagging.

Steps to Building a Sauna Bench

If you’re planning to build your own sauna bench, follow these essential steps:

  1. Plan Your Layout

  2. Measure your sauna space carefully.

  3. Decide on fixed or floating benches.
  4. Sketch a simple plan including bench heights, widths, and spacing.

  5. Select the Right Wood

  6. Purchase lumber rated for sauna use (cedar, aspen, hemlock, or spruce).

  7. Ensure wood is smooth and free from splinters.

  8. Cut Wood to Size

  9. Cut seat and support pieces based on your plans.

  10. Sand all edges, especially corners, for safety and comfort.

  11. Assemble the Frame

  12. Build the support frame first.

  13. Use stainless steel screws (they don’t rust) and strong brackets.

  14. Attach the Slats

  15. Space slats evenly with small gaps for drainage.

  16. Secure with screws or hidden fasteners for a clean look.

  17. Install the Benches

  18. Either mount on the wall (for floating style) or rest on legs (freestanding).

  19. Double-check that all parts are stable, safe, and level.

  20. Finish and Inspect

  21. Wipe benches with a damp cloth to remove dust.

  22. Avoid paint or glossy sealants—stick to sauna-safe natural oils or leave bare for the best experience.

Benefits of High-Quality Sauna Benches

Choosing or constructing good benches isn’t just an aesthetic investment. Here’s how well-made benches enhance your sauna time:

  • Comfort: Well-designed benches allow longer, more relaxing sessions.
  • Hygiene: Proper spacing prevents moisture buildup and mold.
  • Safety: Rounded edges and sturdy construction prevent accidents.
  • Aesthetics: Premium wood and expert design add beauty to your sauna.

Design and Arrangement Tips

1. Placement for Best Heat

  • Upper benches receive the hottest air; lower benches are cooler.
  • Place benches along one or two walls to maximize space.
  • Consider L-shaped or U-shaped arrangements for more social setups.

2. Accessibility

  • Add a step or lower bench for easy movement to top benches.
  • Make sure there’s enough floor space for standing, turning, or laying down.

3. Ventilation

  • Benches should not block vents or heaters.
  • Allow some space between benches and walls for air to circulate.

Practical Tips and Best Practices

  1. Don’t Use Varnish or Paint

  2. Finishes can get sticky and release fumes in high heat.

  3. Routine Cleaning

  4. Wipe benches after each use with water and a soft cloth.

  5. Every so often, scrub gently with a mild soap made for saunas.

  6. Check Regularly

  7. Inspect for loose screws, cracks, or splinters.

  8. Repair or sand rough spots promptly for safety.

  9. Seasonal Maintenance

  10. Tighten fasteners and wipe down with sauna-safe oil annually to keep wood from drying.

  11. Add Comfort

  12. Sauna towels or seat covers protect the wood and make sitting more enjoyable.


Buying Sauna Benches: What to Look For

If you prefer to purchase ready-made sauna benches, look for these features:

  • Quality Wood: Opt for cedar, aspen, or hemlock.
  • Sturdy Build: Test for wobble and check weight ratings.
  • Easy Installation: Pre-drilled holes or mounting hardware included.
  • Proper Size: Choose benches that fit your sauna’s dimensions and user needs.

Cost-Saving Tips When Buying or Building Sauna Benches

  • Compare prices across several sauna supply companies.
  • Consider DIY kits, which can be less expensive than custom options and still deliver quality.
  • If shipping is involved, seek out suppliers that offer bundled deals—sometimes buying bench kits and hardware together saves on shipping costs.
  • Buy local or reclaimed wood to reduce costs and environmental impact.

Common Sauna Bench Challenges and Solutions

  • Warping or Splitting: Use only sauna-approved hardwood, and avoid direct water contact.
  • Loose Slats: Regularly tighten screws and check for wear.
  • Overheating Surfaces: Avoid metal fasteners on seat tops—use hidden mounting or wood plugs.
  • Limited Space: Opt for foldable or floating benches to free up room.

Summary

Sauna benches are vital to a comfortable and enjoyable sauna experience. Whether you buy a ready-made bench or construct your own, focus on suitable wood, ergonomic design, and safe construction. Remember, the best sauna bench should enhance relaxation, be easy to clean, and reflect your style. Take time to plan your sauna space, and you’ll reap the benefits every time you step inside.

Leave 1/2 to 3/4 inch between slats. This ensures air circulation, quick drying, and comfortable seating.
