But with this popularity comes a flood of options. How do you choose? As obsessive hot tub testers who have inflated, filled, and evaluated dozens of models, we’ve spent countless hours in this specific category.

In-Depth Reviews: The Best 4-Person Spas of 2025
1. Coleman SaluSpa Honolulu AirJet
Year after year, the Coleman SaluSpa (in its various forms like the Honolulu, Tahiti, or the classic green) remains our top pick for a reason: it is the undisputed champion of value, durability, and reliability. It’s built like a tank, is incredibly easy to operate, and delivers a fantastic soaking experience that rivals tubs costing twice as much. The Honolulu model, with its attractive grey rattan print, offers a touch of style to this workhorse platform.
Performance and Durability
The foundation of this tub is its DuraPlus™ (formerly TriTech) material. This 3-ply, internally reinforced PVC is incredibly puncture-resistant and holds its shape exceptionally well, even after months of continuous use. The 140 AirJets provide a vigorous, full-body bubble massage that is wonderfully relaxing. The all-in-one pump is a model of simplicity, with an intuitive digital control panel that anyone can master in minutes. For a more detailed breakdown of this platform, our full Coleman SaluSpa review goes even deeper.
What We Love
- Bulletproof durability
- Incredible value for the price
- Simple, foolproof setup and operation
- Large community for support and accessories
What Could Be Better
- Lacks premium features like headrests
- Heating can be slow in cooler weather
2. Intex PureSpa Greywood Deluxe
If the Coleman is the reliable Ford pickup of the hot tub world, the Intex PureSpa Greywood Deluxe is the well-appointed Honda Accord. It takes the core experience and elevates it with thoughtful features, superior comfort, and a stylish design that looks fantastic in a modern backyard. For those willing to spend a small premium, the Greywood Deluxe delivers a noticeably more luxurious experience.
Premium Upgrades
The differences are clear from the start. The Fiber-Tech™ construction creates astonishingly rigid walls you can comfortably sit on. The included package comes with two contoured foam headrests and a multi-color LED light. But the two killer features are the wireless touch control panel you can bring into the tub with you, and the built-in hard water treatment system. This system is a huge long-term benefit, protecting your pump from scale buildup—a common source of problems we discuss in our Intex PureSpa troubleshooting guide. This feature alone makes it a top contender in our Intex vs. Coleman comparison.
What We Love
- Extremely rigid Fiber-Tech walls
- Wireless control panel is a game-changer
- Built-in hard water treatment
- Includes headrests and LED light
What Could Be Better
- Higher price point than base models
- Filter changes can be more frequent
3. Bestway SaluSpa Miami AirJet
Let’s be clear: the Miami is at the coziest end of the 4-person spectrum. Realistically, it’s a luxury 2-person spa. But for those with a tiny patio, a small deck, or a tight budget, the Miami is a dream come true. It offers the core SaluSpa experience—great durability, simple operation, and relaxing bubbles—in the most compact and affordable package available from a top-tier brand.
Compact and Efficient
With a 71-inch diameter and a 177-gallon capacity, the Miami has a very small footprint. This smaller water volume is its secret weapon: it heats up faster and costs significantly less to keep warm than larger tubs. It’s the perfect, low-risk entry point into the world of hot tubs, delivering pure joy without a huge investment in space or money. We explore this model’s unbeatable value proposition in our full Bestway SaluSpa Miami review.
What We Love
- Extremely affordable
- Small footprint fits almost anywhere
- Energy and chemically efficient
- Proven SaluSpa reliability
What Could Be Better
- Very cramped for more than two adults
- Fewer jets than larger models
The Ultimate 4-Person Hot Tub Buyer’s Guide
Choosing the right model goes beyond just picking from a list. To find the perfect spa, you need to understand the key factors that define a great 4-person hot tub. This is the expert criteria we use in all our testing.
What to Look For in a 4-Person Spa
“True” Capacity vs. Listed Capacity
This is the most important concept. “4-Person Capacity” is determined by the manufacturer by how many people can sit upright in the tub. For comfortable, relaxing soaking, a good rule of thumb is “Listed Capacity Minus One or Two.” A 4-person tub is a fantastic, spacious spa for two people, a comfortable fit for three, and a cozy, friendly squeeze for four.
Shape Showdown: Round vs. Square
The vast majority of 4-person inflatable spas are round. This classic shape is great for social, face-to-face conversation. Some premium models (like the Intex Jet & Bubble Deluxe) are square or octagonal. These often feel more spacious as you can sit back into the corners and they more closely mimic the feel of a traditional acrylic spa.
Jet Systems: AirJets vs. HydroJets
Most 4-person spas use AirJets, which create thousands of bubbles for a gentle, full-body massage. For 95% of users, this is perfect. However, if you need a powerful, deep-tissue massage for sore muscles, you’ll want a model with HydroJets. These use a water pump to blast concentrated streams of water, providing a truly therapeutic experience, but at a much higher cost.
Footprint and Weight Considerations
A typical 4-person round spa has a diameter of 71-77 inches. Always measure your space! More importantly, consider the weight. A filled 4-person tub holds around 200 gallons of water, bringing its total weight with occupants to over 2,000 pounds. While fine for a ground-level concrete patio, you MUST confirm the load capacity of any deck before installation.
Owning and Caring for Your 4-Person Spa
Your relationship with your hot tub doesn’t end after purchase. Proper care is the key to longevity and enjoyment.
Setup & Maintenance
Thankfully, setting up any of our recommended tubs is a breeze. Our universal inflatable hot tub setup guide covers the process in detail. Once it’s running, a simple weekly routine is all you need. Because of the smaller water volume compared to giant spas, water chemistry can change more quickly, so consistent testing is key. For the complete, foolproof weekly schedule, our guide to inflatable hot tub maintenance is your essential companion. And for the quarterly deep clean, our step-by-step tutorial on how to clean an inflatable hot tub makes it simple.
Winter Use
It’s critical to know that the standard 4-person models listed here are **not designed for use in freezing weather**. The pump will be destroyed by ice. If you dream of soaking in the snow, you must choose a model with specific freeze-protection technology, which we detail in our guide to the best inflatable hot tub for winter.
The Final Verdict
The 4-person inflatable hot tub truly represents the sweet spot in the market, offering the perfect blend of comfort, affordability, and manageable size. It brings the dream of a personal spa within reach for millions.
After extensive testing, our top recommendation for most people is the Coleman SaluSpa Honolulu for its unbeatable combination of durability and value. However, if your budget allows for an upgrade to more premium features, the Intex PureSpa Greywood Deluxe offers a more luxurious and stylish experience that is well worth the extra cost. No matter which you choose, you’re investing in countless hours of relaxation and well-being.
