Sauna benches and floors are the surfaces you sit and stand on, so keeping them fresh and safe matters. Sit on a towel to keep sweat off the wood, wipe the benches after use, clean both gently and periodically, and let them dry between sessions. Remove duckboards to clean and dry beneath, sand roughened or stained wood lightly, and keep the floor slip-resistant. Clean, dry, well-maintained benches and floors stay comfortable, hygienic and long-lasting.
The benches and floor are the sauna surfaces you’re in most direct contact with — sitting, standing, barefoot and warm. Keeping them clean, dry, safe and comfortable is a small but worthwhile part of sauna care, and it comes down to a few easy habits: a towel, regular light cleaning, drying, and the occasional sanding. This guide covers caring for the surfaces you actually touch.
Benches: use a towel
The simplest, most effective bench-care habit is to sit on a towel. It keeps sweat off the bench wood, which:
- Reduces staining.
- Keeps the benches more hygienic.
- Cuts down cleaning and drying.
Bring a towel to sit on every session — it protects the wood you contact most and makes everything else easier.
Cleaning benches and floor
Keep both fresh with gentle, regular care (see cleaning an outdoor sauna):
- Wipe the benches after use.
- Clean both gently and periodically — warm water and sauna-safe methods, never harsh chemicals or bleach.
- Rinse and, crucially, dry.
- Remove duckboards or removable benches to clean and dry beneath them.
Let them dry
As everywhere in a sauna, drying is what keeps benches and floors fresh. Space the bench boards so they dry, keep the floor free of standing water, and dry the sauna after every use. Damp, sweat-soaked benches stain and smell; dry ones stay fresh. Removable duckboards can be lifted out to dry fully.
Sanding to refresh
Over time, interior wood roughens, greys or stains — especially benches. Light sanding along the grain refreshes the surface, bringing back smooth, clean wood:
- Sand gently, along the grain.
- Clean off the dust afterward.
- Keep the wood bare or use only a sauna-appropriate treatment — never ordinary varnish.
It’s a normal, satisfying part of bench care that keeps them looking and feeling good.
Floor safety: slip resistance
The floor gets wet, and you’re barefoot and warm, so slip resistance matters for safety (see sauna safety). Textured tile, a suitable concrete finish, or wooden duckboards provide grip; smooth wet surfaces are slippery. Keep the floor slip-resistant, especially where you step in and out, and keep it clean and free of standing water.
Dealing with stains
- Sweat and water stains — a gentle scrub with a soft brush and sauna-safe cleaning usually lifts them; rinse and dry.
- Stubborn or greyed wood — light sanding along the grain refreshes it.
Using a towel and drying the benches prevents most staining in the first place.
Common mistakes
- Not using a towel, letting sweat soak and stain the benches.
- Never drying benches and floor, so they stay damp.
- Harsh chemicals or bleach that harm the wood.
- A slippery wet floor with no grip.
- Never sanding roughened, stained wood.
Next steps
Care for benches and floors with a towel, gentle cleaning, drying, occasional sanding, and slip-resistant surfaces. It’s part of the wider maintenance routine and wood care — and it keeps the surfaces you sit and stand on comfortable, hygienic and safe for years.
Frequently asked questions
How do I keep sauna benches clean and fresh?
Sit on a towel to keep sweat off the wood, wipe the benches after each use, clean them gently and periodically, and let them dry between sessions by spacing the boards and drying the sauna. Remove any duckboards or removable benches to clean and dry them separately. Sand lightly if the wood roughens or stains. Clean, dry benches stay fresh and comfortable.
Why should I use a towel in the sauna?
Sitting on a towel keeps sweat off the bench wood, which reduces staining, keeps the benches more hygienic, and cuts down how much cleaning and drying they need. It's a simple habit that protects the wood you're in most direct contact with. Bring a towel to sit on every session — it makes bench care far easier.
How do I care for a sauna floor?
Wipe or lightly clean the floor, rinse if needed, and let it dry, keeping it free of standing water. Remove duckboards to clean and dry beneath them. Keep the floor slip-resistant for safety, since it gets wet and you're barefoot. A floor that drains or dries and stays grippy is both hygienic and safe.
Should I sand my sauna benches?
Yes, when they roughen, grey or stain over time — light sanding along the grain refreshes the surface and brings back smooth, clean wood, which matters most on benches you sit on directly. Clean off the dust afterward, and keep the wood bare or use only a sauna-appropriate treatment, never ordinary varnish. It's a normal part of bench care.
How do I get stains off sauna benches?
A gentle scrub with a soft brush and sauna-safe cleaning usually lifts sweat and water stains; rinse and dry. For stubborn or greyed wood, light sanding along the grain refreshes it. Avoid harsh chemicals and bleach, which harm the wood and leave fumes. Using a towel and drying the benches prevents most staining in the first place.
Are sauna floors a slip hazard?
They can be — the floor gets wet and you're barefoot and warm, so slip resistance matters for safety. Textured tile, a suitable concrete finish, or wooden duckboards provide grip; smooth wet surfaces are slippery. Keep the floor slip-resistant, especially where you step in and out, and keep it clean and free of standing water.
