Keeping your sauna in top condition doesn’t require professional help for every task. This sauna maintenance checklist covers the essential DIY maintenance tasks that will extend your sauna’s lifespan and ensure safe, enjoyable sessions for years to come.
Daily Sauna Maintenance Tasks
After Each Use:
Wipe down benches with a clean, damp cloth to remove sweat and body oils. Leave the door open for 15-20 minutes to allow complete air circulation and moisture evaporation. This simple step prevents mold growth and wood deterioration.
Check the temperature controls. Ensure your sauna reaches the desired temperature and maintains it consistently. Temperature fluctuations may indicate heater issues that need attention.
Weekly Sauna Maintenance Checklist
Clean the floor thoroughly. Sweep or vacuum to remove hair, dust, and debris. Mop with a mild, sauna-safe cleaning solution. Avoid harsh chemicals that can damage wood or create harmful fumes when heated.
Inspect wooden surfaces for splinters or rough spots. Sand lightly with fine-grit sandpaper if needed. This prevents injuries and keeps wood surfaces smooth.
Wash sauna accessories. Clean headrests, backrests, and floor mats with warm water and mild soap. These items accumulate sweat and bacteria quickly.
Monthly Sauna Maintenance You Can Handle
Deep clean all wooden surfaces. Use a specialized sauna cleaner or a mixture of water and white vinegar (1:4 ratio). Scrub gently with a soft brush, working with the wood grain. Rinse with clean water and allow thorough drying.
Check and clean sauna stones. Remove loose debris from heater stones. Rearrange stones to ensure even heat distribution. Replace cracked or crumbling stones immediately—damaged stones reduce heating efficiency and can be safety hazards.
Inspect door seals and hinges. Tighten loose screws on hinges. Check door seals for gaps or wear. Proper seals maintain temperature efficiency and reduce energy costs.
Clean light fixtures and replace bulbs. Dust accumulates on sauna lights. Ensure bulbs are rated for sauna use and replace any that are dimming.
Quarterly Sauna Maintenance Checklist
Examine electrical components. Look for frayed wires, loose connections, or signs of overheating around the heater unit. If you notice anything unusual, contact a qualified electrician—electrical issues are not DIY territory.
Test safety features. Verify that temperature limiters and timers function correctly. These safety mechanisms prevent overheating and equipment damage.
Inspect ventilation systems. Clean air vents to ensure proper airflow. Good ventilation prevents moisture buildup and maintains air quality.
Check structural integrity. Look for warping, cracks, or loose boards in walls, ceiling, and benches. Address minor issues promptly before they become major repairs.
Yearly Sauna Maintenance Tasks
Re-sand benches and backrests. Even with regular care, benches develop rough spots over time. A thorough sanding once yearly keeps surfaces comfortable and splinter-free.
Deep clean behind and under the heater. Dust and debris accumulate in hard-to-reach areas. Turn off power completely before cleaning around electrical components.
Treat wood surfaces if needed. Some sauna owners apply specialized sauna oils or sealants annually. Follow manufacturer recommendations for your specific wood type.
Replace sauna stones completely. Most manufacturers recommend full stone replacement every 1-2 years, depending on usage frequency.
What You Should NOT Do Yourself
While this sauna maintenance checklist covers many DIY tasks, some jobs require professionals:
- Electrical repairs or heater replacement
- Structural repairs involving load-bearing elements
- Gas line work for gas-heated saunas
- Major ventilation system modifications

Signs Your Sauna Needs Professional Attention
Contact a professional if you notice persistent musty odors despite cleaning, uneven heating or cold spots, electrical buzzing or burning smells, excessive moisture accumulation, or visible mold growth that cleaning cannot remove.
Final Thoughts on DIY Sauna Maintenance
Following this sauna maintenance checklist consistently prevents costly repairs and ensures your sauna remains a relaxing, safe retreat. Most maintenance tasks take just minutes but make a significant difference in your sauna’s performance and longevity.
Set reminders on your phone for weekly, monthly, and quarterly tasks. Create a simple log to track completed maintenance—this helps identify patterns and proves invaluable if warranty issues arise.
Regular sauna maintenance you can do yourself saves money and gives you peace of mind that your investment is well-protected. Start with daily habits, stay consistent with weekly cleaning, and your sauna will reward you with years of therapeutic heat and relaxation.
