A well-maintained hot tub offers not only relaxation, but also safety and long-term comfort. Whether you have a wood-fired or electric model, proper maintenance of water, structure and stove is essential.
1. Water - clean, safe, balanced
Change the water completely every 1-2 weeks
Use filtration systems and check them periodically
Test and balance pH and alkalinity:
pH: 7.2 - 7.8
Alkalinity: 80-120 ppm
You can use active oxygen tablets or natural products for light disinfection.
2. Wood - protected and well maintained
Clean surfaces with a soft cloth and warm water
Apply special oils once every 6-12 months
Use a thermal insulation cover for protection
3. Stove - efficiency and safety
For wood stoves:
Empty the ash after each use
Clean the glass door and check the seal
Inspect the chimney for deposits
For electric stoves:
Check the control panel and outlets
Make sure the control unit is protected from moisture
4. General hygiene - monthly maintenance
Clean the inside of the tub with a soft brush
Wash headrests and accessories
Ventilate the hot tub well after use
Avoid lotions and body oils

Children and sensitive persons
Children under 12 can use the sauna or hot tub only under strict adult supervision

Make sure the sauna is installed on a solid, heat-resistant base
