- Electricity: $240-$420 per year
- Chemical maintenance: $300-$400 per year
- Filter replacements: $50-$100 per year
- Total annual cost: $590-$920
Setup and Installation Process
Site Preparation Requirements
Inflating the tub only took about five minutes, and we did not even need any additional tools. Proper site preparation ensures safe installation and optimal performance.
Surface Requirements:
- Level, structurally sound foundation
- Support for 1,500-2,500 pounds total weight
- Access to 110V electrical outlet
- Garden hose connection nearby
- 12-15 inches clearance on all sides
Heating and Fill Process
Initial heating requires patience but minimal effort. Once filled and the heater was turned on, Annie noted that every hour, this hot tub heated between 2°C and 2.5°C. Complete heating from cold typically takes 24-48 hours.
Setup Timeline:
- Inflation: 5-10 minutes
- Water filling: 1-2 hours
- Initial heating: 24-48 hours
- Ready for use: 1-2 days total
Maintenance and Longevity
Regular Maintenance Tasks
Water quality maintenance involves routine filtration monitoring and chemical balancing. Test strips monitor pH and chlorine levels weekly, while filter cartridges require replacement every 2-4 weeks during regular use.
Weekly Maintenance:
- Test water chemistry with strips
- Clean waterline and surfaces
- Check and clean filter cartridges
- Monitor water level and temperature
- Remove debris from water
Expected Lifespan
You can expect to receive around 5-7 years of use out of an inflatable hot tub compared to 20+ years of use from a hardshell hot tub. Proper winter storage and UV protection extend lifespan significantly.
Longevity Factors:
- Quality of construction materials
- Frequency of use and maintenance
- Climate and weather exposure
- Storage practices during off-season
- Manufacturer warranty coverage
Customer Experience and Reliability
Real-World Capacity Considerations
Based on our experiences with each hot tub, we discovered that the reported capacity of each tub was frequently overstated and that having lots of jets is imperative. Comfortable adult capacity typically runs 1-2 people below manufacturer claims.
Realistic Capacity Guidelines:
- 4-person rated: Comfortable for 2-3 adults
- 6-person rated: Comfortable for 4-5 adults
- Consider user size and desired comfort level
- More jets provide better massage experience
Brand Reliability Rankings
Customer satisfaction varies significantly between manufacturers. We chose the Intex Purespa 6 person spa for our best inflatable spa of the year due to its 5-year shell warranty, trusted name, available add ons, and low initial price.
Reliability Rankings:
- Intex: Excellent warranty and customer service
- Lay-Z-Spa: Superior energy efficiency and heating
- Coleman SaluSpa: Best value and ease of use
- Bestway: Enhanced durability and construction
Seasonal Use and Storage
Year-Round Operation
Modern inflatable hot tubs support four-season use with proper features. FreezeShield technology prevents pump damage during freezing temperatures, while insulated covers retain heat efficiently.
Winter Operation Requirements:
- FreezeShield or equivalent freeze protection
- Insulated cover for heat retention
- Regular use to prevent freezing
- Monitor for ice formation around jets
- Consider temporary indoor storage in extreme cold
Off-Season Storage
Proper storage extends equipment life and prevents weather damage. Deflation and indoor storage protect against UV degradation and temperature extremes.
Storage Best Practices:

- Thorough drying before storage
- Climate-controlled storage environment
- Original packaging or storage bag
- Annual inspection before reinstallation
