When trying to determine what size hot tub you need for 8 people, there are a few key factors to consider. The main elements are the number of people who will be using the hot tub, the amount of personal space desired, and the different seating options available. Taking all of these elements into account will help you select the right sized hot tub to comfortably fit 8 adults.

Consider the Number of People
The most obvious factor is the number of people – in this case 8 adults. Most hot tub manufacturers provide a general guideline for how many people each model can accommodate. However, these numbers assume average adult sizes and moderate personal space. If your group of 8 has larger builds or wants more generous space, you may need to size up from the standard recommendation.
As a general rule of thumb, you can estimate needing at least 10-20 gallons of capacity per person in the hot tub. Most models range from 200-500+ gallons, so for 8 adults you would want a minimum of around 300 gallons. However, more space is usually better for soaking comfort.
Determine Desired Personal Space
In addition to the number of people, you also need to consider how much personal space each person should reasonably have. While some scenarios may call for cozy quarters, most people prefer to have adequate room to stretch out and relax.
As a baseline, you generally need at least 2-3 feet of space per person. But more spacious 3-4 feet per person is ideal for 8 adults. This not only allows for more comfort, but makes entering and exiting the hot tub easier without too many bodies crowding the space.
Understand Seating Capacity Options
When evaluating different hot tub models, you’ll notice a range of seating options. Many have built-in bench seating around the interior perimeter. But you’ll also see models with lounge seats, spa captain’s chairs, and more. The seating configuration directly impacts the total number of spots available.
For a group of 8 adults, you’ll want seating capacity of 8-10 spots minimum. This provides each person their own space while leaving some extra room. Having additional unused seats also means you can accommodate another couple guests if needed.
Common 8-Person Seating Styles
- Bench seats – Typically fits 6-8 adults
- Lounge seats – Fits 5-7 adults
- Captain’s chairs – Fits 4-6 adults
Bench seating is usually the best option for maximizing capacity for larger groups. But the other styles may provide more customizable comfort if you want various reclined positions.
Recommended Hot Tub Sizes
Taking all these factors into account, the recommended hot tub sizes for 8 adults are:
| Hot Tub Size | Gallon Capacity | Seating Capacity |
|---|---|---|
| 5-person | 200-300 gallons | 5-7 adults |
| 6-person | 300-400 gallons | 6-8 adults |
| 7-person | 350-450 gallons | 7-9 adults |
| 8-person | 400-500 gallons | 8-10 adults |
As you can see, a 6-7 person hot tub is ideal for a group of 8. This provides at least 300 gallons of water capacity and seating for 6-9 adults. While an 8-person model would also work, a 6-person is often sufficient unless your group wants even more space.
Other Considerations
In addition to size, there are a few other factors to keep in mind when shopping for an 8-person hot tub:
Dimensions
Make sure the hot tub dimensions allow it to properly fit in your planned installation area. Measure the space and compare to the hot tub specs.
Jets
More jets provide better massaging action. Look for at least 30-50 jets for 8 users to have adequate pressure.
Controls
Intuitive controls and multiple user settings allow customization for each person.
Insulation
Better insulation means more efficient operation. Look for at least 2-3 inches of foam insulation.
Cover
Get a sturdy tapered cover that’s secured by locks. This ensures safety, retains heat, and prevents debris from falling in.
Budgeting
On average, expect to spend $4,000-$8,000+ on a new hot tub equipped for 8 people. Larger sizes with more features will range into $10,000+ territory. Consider the long-term maintenance costs as well when budgeting.
Top Hot Tub Brands
Some of the top rated manufacturers of 6-8 person hot tubs include:
- Jacuzzi

Installation Requirements
Properly installing a large 300+ gallon hot tub takes some planning. Here are some key requirements to keep in mind:
- Reinforced concrete pad
- Dedicated GFCI protected 220V electrical circuit
- Improved site drainage and grading
- Nearby source of water for filling/topping off
- Access path for delivery trucks
Taking care of these elements ahead of time ensures safe installation and optimal hot tub performance. Hire a professional installer if needed.
Conclusion
When shopping for an 8-person hot tub, focus your search on 6-7 person models with generous seating capacity. Prioritize adequate water capacity of at least 300 gallons and seating for 8-10 adults. Also pay attention to the overall dimensions, number of jets, controls, insulation, cover, and other features that impact comfort and performance. With good planning and preparation, installing the perfect 8-person hot tub for friends and family to enjoy for years is an achievable goal.
