An inflatable hot tub can add a relaxing soak to your backyard without the fixed installation of a built-in spa. The best value depends on more than the tub’s upfront cost: capacity, insulation, water care, and the space you have available all matter. These four options range from a compact two-to-four-person spa to a larger model with app controls. Compare their features carefully, and check the current listing for price and availability before you buy.

Our Picks: Best Cheap Inflatable Hot Tub reviews
1. INTEX PureSpa Bubble Massage Spa Set: Best All-Around Pick
This Intex PureSpa is a round, portable spa designed for up to four people. Its Fiber-Tech beam construction is intended to give the tub structural stability while keeping the seating surface comfortable. The built-in hard water treatment system is another useful feature, since it treats the water to make it gentler on skin, clothes, and the spa system.
The set includes a high-density foam cover designed to reduce heat loss. Intex says the cover can improve energy efficiency by as much as 50%; actual energy use will depend on factors such as weather, setup, and how often you use the spa. The heater has a stated temperature range of 68–104°F, and the tub holds 210 gallons of water.
At 77 inches across on the outside and 57 inches across on the inside, it has a smaller usable area than the outer measurement might suggest. That makes it a reasonable fit for couples or a small household, but four adults may have limited room to spread out. Compared with the SaluSpa, it offers a larger stated water capacity; the SaluSpa, in turn, specifically lists a freeze-protection feature.
Pros:
- Fiber-Tech construction is designed for added stability.
- Built-in hard water treatment is included.
- Insulated cover helps limit heat loss.
- Temperature range and water capacity are clearly specified.
Cons:
- The 57-inch internal diameter may feel snug with four adults.
- The listing does not provide a specific jet count.
Verdict: Choose this PureSpa if you want a well-rounded four-person option with hard water treatment and a heat-retaining cover.
2. Bestway SaluSpa Hot Springs: Best for Energy-Conscious Use
The SaluSpa Hot Springs is a round inflatable spa sized for two to four adults. Its EnergySense insulated walls and cover are described as up to 40% more energy-efficient than similar hot tubs. That claim makes insulation one of this model’s main selling points, though your actual energy use will vary with the conditions and how you operate it.
The tub uses an AirJet bubble massage system. Its multi-function pump handles inflation, heating, and filtration, and the water can be heated to 104°F. The internal MaxHold beams are designed to help the spa retain air pressure, while the three-layer Tritech exterior is intended to resist punctures and wear.
Two practical features set this model apart: Freeze Shield is designed to protect the pump and liner in cold weather, and a power-saving timer lets you schedule the water temperature up to 40 days in advance. The set also includes a cover, filter cartridge, chemical dispenser, and repair patch. Its 71-by-26-inch dimensions and 177-gallon capacity put it on the smaller side compared with the Intex PureSpa, so consider how much room you want inside.
Pros:
- Insulated walls and cover are designed to reduce heat loss.
- Freeze Shield and a programmable temperature timer are included.
- The pump combines inflation, heating, and filtration functions.
- Includes a cover, filter cartridge, chemical dispenser, and repair patch.
Cons:
- Its listed capacity and dimensions may feel limited for four adults.
- The energy-efficiency percentage is a manufacturer comparison, not a guarantee of your energy savings.
Verdict: Pick the SaluSpa if insulation, scheduled temperature control, and cold-weather pump protection matter more to you than maximum interior space.
3. TIMSATIO Inflatable Hot Tub: Best for Bigger Groups and App Control
The TIMSATIO is the largest listed option here, with an 81-inch outside diameter, a 70-inch internal seating area, and a stated capacity of 158 gallons. The manufacturer describes it as suitable for four to six adults. The extra interior room may make it more practical for family gatherings than the smaller two-to-four-person tubs, although the number of people who fit comfortably will depend on their size and how much space they want.
It has 150 air jets arranged around the tub for bubble massage, plus Wi-Fi app control for adjusting the temperature up to 104°F, turning on the bubbles, setting heating timers, and checking filter status. The listing also describes an auto-inflate system. The included kit is said to have an insulated cover, ground cloth, two replacement filter cartridges, and a carry bag.
There is an important buying caveat: this product is marked unavailable in the supplied product information. Check the listing before planning around it, and compare its current availability with the other options. The product description also cuts off after mentioning built-in LED ambient lighting, so confirm the full included-feature list on the product page. Unlike the SaluSpa, the supplied details do not specify a freeze-protection system or a warranty.
Pros:
- Largest stated seating area among these four options.
- App control includes temperature, bubble, timer, and filter-status functions.
- Lists 150 air jets and an auto-inflate system.
- Includes a cover, ground cloth, replacement filters, and carry bag.
Cons:
- Marked unavailable in the supplied product information; availability may change.
- The product description is incomplete, so verify its full specifications and included items.
Verdict: Consider the TIMSATIO if you need more room and want app controls, but verify availability and the complete product details before buying.
4. INTEX SimpleSpa: Best Straightforward Four-Person Option
The INTEX SimpleSpa is a portable four-person hot tub with 100 air jets. Its heated-air bubble system lets you adjust the water temperature, while the included insulated cover and ground cloth are designed to help the water stay warm between sessions. The listing does not state the tub’s dimensions, water capacity, or temperature range, so compare those details on the product page if they are important to your setup.
The spa uses horizontal beam construction and a mesh exterior intended to provide support and resist punctures and abrasions. It also has a hard water treatment system to help reduce mineral buildup. For routine care, the integrated control box allows access to the filter, and the set includes two S1-type filter cartridges.
Compared with the PureSpa, the SimpleSpa provides a specific jet count and two replacement cartridges, but the supplied details are less complete about size and heating specifications. It may suit shoppers who want a simple bubble-massage setup with basic water-treatment features, provided the missing measurements work for their space.
Pros:
- Includes 100 air jets for bubble massage.
- Hard water treatment is built in.
- Insulated cover and ground cloth are included.
- Comes with two S1-type filter cartridges and an accessible filter setup.
Cons:
- The supplied details do not state its dimensions or water capacity.
- The listed specifications do not give a water temperature range.
Verdict: Choose the SimpleSpa if you want a four-person Intex model with 100 jets and hard water treatment, and confirm its size and heating details before ordering.
How to Choose a Cheap Inflatable Hot Tub
Match the tub to the number of people who will use it
Capacity labels are a starting point, not a promise that everyone will have room to stretch out. Check the inside dimensions when they are available, since the outside diameter includes the tub walls. A model listed for two to four people may work best for a couple or a small household, while a larger interior can be more comfortable for group use. If you expect to host often, compare the seating area rather than relying only on the advertised person count.
Look closely at insulation and heat retention
Heating water takes energy, and heat loss can affect how often the heater needs to run. An insulated cover and insulated walls can help retain warmth, while an included ground cloth can separate the spa from the surface beneath it. Manufacturer efficiency claims are useful for comparing features, but they do not guarantee a specific utility bill. Keep the cover on when the tub is not in use and consider your local weather when choosing a model.
Check the heater range and cold-weather features
Compare the stated maximum temperature and full temperature range, not just the word “heated.” Some models also list features intended to protect the pump or liner during cold conditions. For example, the SaluSpa specifies Freeze Shield; not every product in this group lists a similar feature. Follow the manufacturer’s instructions for operating and storing the spa, especially when temperatures drop.
Consider water care and filter replacement
Inflatable spas still need regular water care. Hard water treatment, included filters, and an accessible filter cartridge can make upkeep more manageable, but they do not remove the need to follow the maker’s water-care instructions. Check what type of filter the tub uses and whether replacement cartridges are easy for you to find. Also review what comes in the box, since a chemical dispenser is included with the SaluSpa but not specified for every model.
Choose the features you will actually use
Bubble jets, app controls, timers, and auto-inflation can add convenience, but they are not equally important to every buyer. The TIMSATIO lists app-based temperature and timer controls, while the Intex options emphasize construction and water treatment. If a feature is central to your choice, confirm it in the complete product listing, particularly when the description is incomplete.
Measure your setup area and check what is included
Measure the spot where you plan to place the tub and allow room to reach the pump and controls. Check the product’s filled weight and placement requirements in the manufacturer’s instructions before using it on a deck or other elevated surface; those specifications are not provided for every model here. Also verify the cover, ground cloth, filters, and repair items included with the exact listing you choose.
Compare total value, not just the initial price
Prices and availability can change, so check the current listing rather than relying on a past price. For a fair comparison, weigh the included accessories, insulation, water-care features, warranty information, and replacement-filter needs alongside the purchase cost. A low upfront price may not be the best value if the tub lacks a feature you need or does not fit your space.
Frequently Asked Questions
Which inflatable hot tub is best for a small household?
The INTEX PureSpa and Bestway SaluSpa are both listed for up to four people. The PureSpa has a 210-gallon capacity, while the SaluSpa lists a 177-gallon capacity and dimensions of 71 by 26 inches. Compare the interior space and your preferred features before choosing.
Which option has the most space?
The TIMSATIO lists an 81-inch outside diameter and a 70-inch internal seating area, and is described as suitable for four to six adults. It is marked unavailable in the supplied product information, so check its current listing before making plans to buy it.
Do inflatable hot tubs use a lot of electricity?
Energy use depends on the model, outdoor temperature, how often you use the spa, and how well you retain heat. Insulated covers and walls are designed to reduce heat loss, but the supplied product details do not provide a specific electricity-use estimate for any of these tubs.
Can I leave an inflatable hot tub outside in cold weather?
Check the manufacturer’s instructions for the specific model and the temperatures where you live. The SaluSpa lists Freeze Shield as a feature intended to help protect its pump and liner in cold weather. The other supplied descriptions do not specify an equivalent feature, so do not assume they have one.
Do inflatable hot tubs need chemical water care?
They require ongoing water care, even when they include a hard water treatment system or filter. Follow the manufacturer’s instructions for keeping the water clean and for replacing filters. Hard water treatment is not a substitute for routine spa maintenance.
Are the listed person capacities comfortable for everyone?
Not necessarily. The capacity is a guide, and comfort depends on the tub’s interior dimensions and the size of the people using it. Check the inside measurements when available; the PureSpa, for example, has a listed 57-inch internal diameter despite its 77-inch outside measurement.
Which model is the best value?
That depends on the features you need and the current price. The PureSpa has a strong mix of stated capacity, hard water treatment, and an insulated cover. The SaluSpa emphasizes insulation and cold-weather protection, while the SimpleSpa offers 100 jets and includes two filter cartridges. Compare current prices and full specifications before deciding.
Final Recommendation
For most shoppers choosing among these options, the INTEX PureSpa is the most balanced pick because it combines a stated 210-gallon capacity, hard water treatment, Fiber-Tech construction, and an insulated cover. Choose the Bestway SaluSpa if its insulation, timer, and Freeze Shield features better fit your needs. The SimpleSpa is a straightforward alternative with 100 jets, while the larger TIMSATIO may appeal to groups if it is available and its complete specifications check out.
