Determining the water capacity of your plug and play model is important for maintenance, heating efficiency, and finding the right location to set it up. So how many gallons of water do portable hot tubs hold?
Plug and play hot tubs are freestanding, inflatable spa models designed for quick and simple setups. They get their name from the ability to just “plug and play” – requiring only an electrical outlet to power the hot tub and bring the water to your desired soaking temperature.
Key features that make them convenient and portable include:
- Inflatable design composed of durable PVC or polyester walls surrounding the inner hot tub structure
- Lightweight hollow walls for insulation
- Simple inflation using a built-in air pump
- Integrated water jet system
- Attached control panel and heating system
- Plug that connects to a standard outlet
Their portable construction allows you to set them up either indoors or outdoors and move them around your space with relative ease. The main infrastructure of filters, heating, and power connects right to the hot tub walls.
What Capacities Are Available?
Plug and play hot tub capacities generally range from 200 to 450 gallons. Most models fall between 300-400 gallons for a spacious soaking experience. The variance depends on the dimensions of the tub.
Here is an overview of common portable hot tub sizes:
| Number of People | Length x Width x Height | Average Gallon Capacity |
|---|---|---|
| 2 person | 55″ x 55″ x 28″ | 200 gallons |
| 4 person | 71″ x 71″ x 31″ | 260 gallons |
| 6 person | 85″ x 85″ x 36″ | 400+ gallons |
The number of gallons affects the overall weight and dimensions of the hot tub when set up and filled. This is an important factor when determining where you want to place it. More water equals more weight. Most backyards can accommodate larger units, while smaller hot tubs are better for decks and indoor installation.
How Many Gallons Do You Need?
The number of gallons your hot tub holds impacts your overall experience. Here’s how water capacity makes a difference:
Heating Time
More water takes longer to bring up to temperature – an important consideration in climates with cooler soaking seasons. However, once heated, more gallons retain warmth effectively.
Example:
- 200-gallon hot tub takes 1-2 hours to heat
- 400+ gallon hot tub takes 4-6+ hours to heat
Soaking Depth
Higher gallon capacity allows for deeper water levels when you fill the tub. Immersing in shoulder-height water provides optimal therapeutic benefits.
Example Soaking Depths:
- 200 gallon tub = 3 feet deep
- 400 gallon tub = 4 feet deep
Filtration Cycle Efficiency
The greater the volume of water circulating through your hot tub system, the better job it can do filtering out contaminants. More gallons may mean less frequent water changes.
Example:
- 200-gallon tub may need drained and refilled every 2-3 months
- 400-gallon tub may only need drain and refill 1-2 times a year
How Many Gallons Should You Choose?
When selecting your plug-and-play hot tub, the “right” capacity comes down to your budget, space, and soaking preferences.
Budget
Higher gallon tubs come at a higher price point. And more water equals higher electric bills for heating.
Cost Comparison:
| Gallons | Hot Tub Price | Estimated Yearly Electric Cost |
|---|---|---|
| 200 | $3,000+ | $150+ |
| 400 | $4,000+ | $350+ |
Space
Consider if you have a large enough flat location for the tub dimensions when filled. Measure doorways if bringing indoors.
Soaking Preferences
Do you want to soak simultaneously with family or friends? Plan for 20-25 gallons per bather. More volume may suit larger groups.
Heating and Electrical Requirements
An important related factor is the hot tub’s electrical specifications for powering the heating system.
Plug and play hot tubs pull a significant amperage
Anywhere from 15 to 50 amps depending on heating wattage and number of jet pumps. You need a properly grounded, GFCI-protected outlet matched to your hot tub electrical configuration. This often requires an electrician to install.
Power Draw Comparison:
| Hot Tub Size | Heater (watts) | Jet Pumps | Electrical Requirements |
|---|---|---|---|
| 200 gallon | 1500-2000 watts | 1-2 | 20-30 amp breaker |
| 400+ gallon | 4000+ watts | 2-3 | 50 amp breaker |
Improper power supply can lead to damage over time and presents safety hazards.
Summary
When asking “how many gallons are in a plug and play hot tub” consider:
- The average capacity ranges from 200-450 gallons
- More gallons allow deeper soaking but longer heat times
- Choose capacity based on budget, space, and number of people soaking
- Ensure proper electrical setup for water heating requirements
Selecting the right size portable hot tub comes down to your needs and preferences. Just be sure to account for the footprint dimensions, weight, electrical demands, and costs associated with higher gallon capacities. Then you can look forward to enjoying the affordable luxury of a plug-and-play spa experience tailored to your lifestyle!
