Our Picks: Best Jetted Tub With Heater reviews
1. Empava 71-Inch Tub With Whirlpool Jets and Air Bubbles
This back-to-wall Empava combines 10 adjustable water jets with 10 air jets. You can use the whirlpool massage, gentle bubbles, or both. Two built-in waterfalls and color-changing lighting add atmosphere, while the included chrome faucet and handheld shower help create a coordinated setup.
The inline heater is designed to maintain already-warm water, not heat a cold tub quickly. It stops heating at 104°F. The tub measures 70.9 by 33.7 inches, has a listed 13.6-inch soaking depth, and holds 67 gallons. Those dimensions and its single-person design make it a more compact choice than the two-person models here.
Installation needs careful planning: the listing specifies two separate 110/120V, 15A dedicated GFCI circuits. You also need to fill the tub until the water is 1–2 inches above the highest jet before starting the massage system. That safeguard matters because the pump should not run dry.
Pros:
- Offers both adjustable water jets and air bubbles.
- Includes a heater, two waterfalls, and color-changing lighting.
- Includes faucet, handheld shower, pillow, drain, and overflow components.
- ETL-certified, according to the product details.
Cons:
- Requires two dedicated GFCI circuits, which may complicate installation.
- The heater maintains warm water rather than quickly heating a cold bath.
Verdict: Choose this Empava if you want both water-jet massage and air bubbles in a single-person, back-to-wall tub and can meet its electrical requirements.
2. Empava 59-Inch Corner Whirlpool Tub for Two
This triangular Empava is made to use a bathroom corner and accommodate two adults. It measures 59.1 inches on each side and has a listed 91-gallon capacity. Ten adjustable directional water jets, powered by a 1.0 HP motor, provide the whirlpool massage; this model does not list a separate air-jet system.
An inline heater helps maintain bathwater up to 104°F, while a waterfall spout and seven-color underwater LED lighting add relaxing touches. The tub has two headrests and an acrylic shell reinforced with fiberglass resin, plus a 304 stainless steel frame. Its smart touch controls and GFCI electric leakage protection are also noted in the product details.
The corner shape can make good use of an otherwise awkward area, but the large footprint and water capacity still call for careful checks of bathroom access, floor support, plumbing, and electrical requirements. The listing includes faucets, a handheld shower, drain and overflow parts, and adjustable leveling feet. It also describes a three-year limited warranty, so check the listing for the applicable terms.
Pros:
- Corner layout is designed to fit two adults.
- Ten adjustable water jets and a 1.0 HP motor.
- Includes an inline heater, waterfall spout, and color-changing lighting.
- Includes a hardware kit and lists a three-year limited warranty.
Cons:
- Its nearly five-foot-square footprint may not suit smaller bathrooms.
- Offers water jets, but the supplied details do not list air bubbles.
Verdict: This is a strong fit if you want a two-person corner whirlpool with a heater and have enough room for its broad footprint.
3. Empava PRO 71-Inch Two-Person Tub With 40 Jets
This roomy rectangular Empava is designed for two people, with 16 adjustable hydrotherapy jets and 24 air jets. The water jets offer a more focused massage, while the air jets create a gentler bubbling sensation. You can use those different styles to suit your preferences during a soak.
The tub measures 71 by 51 inches, has an 18.5-inch soaking depth, and lists a maximum capacity of 119 gallons. Dual cushioned headrests, a wide waterfall, and eight sets of color-changing lighted bubbles add to its spa-style setup. Its size and capacity make bathroom clearance, water supply, floor support, and access for installation especially important to verify.
The inline heater is intended to extend a soak by maintaining warm water. It operates when the water is approximately 77°F or warmer and stops heating at 104°F; it is not meant to rapidly warm cold water. A pipe-flushing function is included to help rinse the internal lines after use, which can be useful for routine care.
Pros:
- Combines 16 hydro jets with 24 air jets.
- Spacious two-person design with dual headrests.
- Includes an inline heater, waterfall, and lighted bubbles.
- Pipe-flushing function helps rinse the internal plumbing after use.
Cons:
- Its large dimensions and 119-gallon maximum capacity demand careful planning.
- The heater maintains warmth rather than heating cold water quickly.
Verdict: Pick this model if you want a large two-person tub with both hydro and air massage, and your bathroom can accommodate its size and water needs.
4. Aoowow 61-Inch Freestanding Tub With 16 Water Jets
This rectangular freestanding whirlpool tub is marketed for two people and measures 61 inches long. Its center drain placement is intended to let the tub sit flush against a wall, giving it a freestanding look without requiring it to stand away from the wall. Check the room layout and access dimensions before deciding whether it will fit your renovation.
The massage system has 16 adjustable water jets: four larger full-body jets and 12 targeted back jets. A built-in heater maintains water between 97°F and 104°F, while a digital panel controls temperature and jet intensity. Color-changing LEDs add ambient light, and the listed filtration system is intended to help keep bathwater clean and protect internal components.
The product details describe a non-porous acrylic shell, a UL-certified motor, and a UPC-certified drain. However, the supplied information does not state a water capacity, so you should confirm the tub’s specifications and your installation needs before purchase. It also lists water jets, not a separate air-bubble massage.
Pros:
- Wall-aligned design may suit a modern bathroom layout.
- Sixteen adjustable jets include focused back-massage jets.
- Heater maintains water between 97°F and 104°F.
- Includes a digital control panel, color LEDs, and water filtration.
Cons:
- The supplied details do not list the tub’s water capacity.
- Does not list air jets or air-bubble massage.
Verdict: Consider the Aoowow if you prefer a rectangular, wall-aligned tub with adjustable water jets and digital temperature control, but confirm capacity and installation details first.
5. Empava 59-Inch Corner Tub With Heater and Chromatherapy
This Empava corner tub is designed for two and measures about 59.5 inches wide and deep. Its listed interior measures 40 by 31 inches, with a 17-inch interior height. The tub has 10 water jets powered by a 1.0 HP motor, plus chromatherapy lighting and a blue glass detail.
The inline heater is specified to maintain water between 96.8°F and 104°F. The product details make clear that you should start with hot water in the tub; the heater is not intended to warm cold water. The tub is listed at 91 gallons and uses a fiberglass-reinforced acrylic shell with a 304 stainless steel support frame.
Its corner layout and reclining back are aimed at shared soaks, but the dimensions and water volume mean you should check floor support, plumbing access, and clearance before installation. The listing also identifies ETL certification and a UL-certified motor. Unlike the larger Empava PRO model, this one lists 10 water jets and does not describe a separate air-jet system.
Pros:
- Corner layout and reclining design are made for two people.
- Ten water jets and a 1.0 HP motor provide whirlpool massage.
- Includes an inline heater and chromatherapy lighting.
- Lists ETL certification and a fiberglass-reinforced acrylic build.
Cons:
- The heater maintains hot water but is not designed to heat cold water.
- Its 91-gallon capacity and large footprint need careful installation planning.
Verdict: This is a practical choice if you want a two-person corner whirlpool with a heater and chromatherapy, and you can supply hot water and accommodate its size.
How to Choose a Jetted Tub With a Heater
Measure the room and the route into it
Start with the tub’s outside dimensions, not just the space where it will sit. Leave room for the faucet, controls, plumbing access, and any nearby doors or fixtures. Also measure hallways, stairways, and door openings along the delivery route. A large tub may fit the bathroom but still be difficult to bring inside.
Choose a tub shape that suits your layout
Corner tubs can make use of an open corner and often offer a wide bathing area, but their square footprint can take up substantial floor space. Rectangular and back-to-wall models may work better along a straight wall. For a freestanding-style tub, check whether the drain location and wall clearance match your bathroom plan.
Compare the jet types and layout
Water jets circulate bathwater for a more focused massage. Air jets create bubbles for a gentler feel. Some tubs include both, while others list only water jets. Look at the number and placement of the jets, and consider whether you want adjustable direction, targeted back massage, or a simpler system.
Understand what the heater does
These tubs use inline heaters to help maintain warm bathwater during a soak. They are not a substitute for filling the tub with hot water, and they are generally not designed to heat a cold tub quickly. Check the stated temperature range and shutoff temperature, then follow the manufacturer’s instructions for use.
Check electrical and plumbing requirements
Hydrotherapy pumps, heaters, and lighting need the right electrical setup. The 71-inch Empava with both water and air jets, for example, specifies two separate dedicated GFCI circuits. Requirements vary by model, so review the full installation instructions and ask a qualified electrician or plumber to confirm what your bathroom needs before you buy.
Account for water capacity and floor support
Capacity can range from 67 gallons for the single-person Empava to a listed maximum of 119 gallons for the larger PRO model. The full load also includes the tub and bathers. Ask a qualified contractor to check that your floor can support the filled tub, especially for a larger model or an upper-floor bathroom.
Consider cleaning and ongoing care
Jetted tubs have internal plumbing that needs proper care. The Empava PRO model includes a pipe-flushing function to help rinse its lines after use. For any tub, follow the maker’s cleaning and maintenance instructions, and make sure the installation leaves access to the pump and plumbing where required.
Frequently Asked Questions
Does an inline heater warm cold bathwater?
Not quickly. The models here describe their heaters as a way to maintain already-warm bathwater during a soak. Fill the tub with hot water and follow the instructions for the specific model.
What temperature do these tub heaters reach?
The listed maximum varies by model. Several stop heating at 104°F, while the Aoowow model lists a range of 97°F to 104°F. Check the product details and controls for the tub you are considering.
Can I use a jetted tub before it is full?
No. Follow the manufacturer’s fill instructions before starting the pump. The 71-inch Empava with 20 jets specifically says to fill the water 1–2 inches above the highest jet and warns against running the massage system dry.
Do all the tubs in this guide include air jets?
No. The first Empava lists 10 air jets and 10 water jets, and the Empava PRO lists 24 air jets and 16 hydrotherapy jets. The other three models list water-jet massage without a separate air-jet system in the supplied details.
Which tub is designed for two people?
The two corner Empava models, the Empava PRO 71-inch model, and the Aoowow 61-inch model are described as two-person tubs. Actual comfort depends on the tub’s interior size and the people using it, so compare the interior dimensions where provided.
Do jetted tubs need a dedicated electrical circuit?
Electrical needs depend on the model. The 71-inch Empava with both massage systems specifies two separate 110/120V, 15A dedicated GFCI circuits. Check the installation guide for your selected tub and have a qualified electrician verify the setup.
Final Recommendation
For the widest choice of massage styles, the Empava PRO 71-inch model combines hydro jets and air jets in a spacious two-person tub, but its size and capacity call for careful planning. If you want a more compact single-person option with both jet types, consider the 71-inch back-to-wall Empava. For a corner layout, compare the two Empava models by heater details, features, and installation requirements before choosing.
