Best Smart Luxury Bathtubs With Jetted Massage in 2026

Have independent reviewers actually tested these five tubs?

No, and we would rather say so than imply otherwise. We checked our registered outlet list against all five listings in August 2026 and found no independent review of any of these exact models. Bob Vila's whirlpool-tub roundup ranks two other Empava tubs, the 59JT319 corner and the 71JT667B alcove. Family Handyman's spa-tub roundup ranks a different Woodbridge combination tub. Six Storeys ranks a heated 72-inch WOODBRIDGE whirlpool that is not the model reviewed here. Attributing any of those verdicts to the products on this page would be inaccurate, so every specification in this guide is read from the manufacturer listing instead, and the ranking is our own composite applied to those published figures.

Why are there two Empava PRO Series tubs, and how do they differ?

They are genuinely different products and the difference is worth understanding before you order. The first is 70.9 by 51.2 inches, holds 119 gallons and publishes 40 jets on a 3430W chassis with a built-in clean cycle. The second is 70.9 by 48 inches, holds 110 gallons and publishes 28 jets, split into 12 water jets and 16 air jets, with a 2790W heater and a dedicated pipe-flushing setting. The wider tub delivers more jets and more water; the narrower one adds the flushing cycle and a three-year warranty covering parts and labor. Roughly a thousand dollars separates them.

What is the difference between water jets and air jets?

Water jets push pressurized water through a small number of directional nozzles, which concentrates force and suits muscle tension and post-exercise recovery. Air jets push warmed air through many smaller outlets, producing a gentler full-body effervescence better suited to general relaxation and circulation. Four of the five tubs in this guide combine both systems, which is why the combination bonus in our scoring separates them less than it would in a broader roster. The genuine outlier is the 67-inch Empava, which publishes seven hydromassage nozzles and no air system at all.

What electrical work will a jetted tub need?

Expect dedicated circuits, and read each listing rather than assuming a category standard. The WOODBRIDGE specifies two dedicated 15-amp 110-volt GFCI breakers. The flagship Empava draws 3430 watts, the pipe-flushing Empava combines a 2790-watt heater with a 350-watt air system, and the 67-inch Empava is the lightest at 560 watts. This Old House notes that whirlpool and freestanding tubs may also require additional floor support alongside new plumbing and electrical connections. If your bathroom shares a circuit with other high-draw fixtures, get an electrician to price the work before you order the tub.

How do you keep the jets clean?

Run a flush cycle regularly and drain the tub completely after every soak, because standing water inside jet plumbing is the condition mould and mildew need. Bob Vila's coverage of the category is direct about this: a jetted tub with an internal pipe system requires more maintenance than a standard tub, and frequent cleaning matters specifically to prevent mould and mildew forming in the pipes. A manual flush means filling above the highest jet, adding a dedicated jet cleaner, running the system, draining and then rinsing with clean water. Two tubs here reduce that burden by design: the WOODBRIDGE uses stainless steel full-draining jets, and the pipe-flushing Empava routes fresh water through the plumbing path on a button press.

Which of these tubs genuinely seats two people?

Three of them, and exterior length is not how you tell. The flagship Empava states two-person seating in a 70.9 by 51.2 inch shell. The pipe-flushing Empava publishes a 38.7 by 36.4 inch inner basin with dual padded headrests. The Harmony 70 is described as a two-person tub in its own title. The WOODBRIDGE, despite a 71-inch exterior, publishes a seating dimension of 41.75 by 19.625 inches, which seats one bather; the 67-inch Empava is single-ended with a 43.31 inch basin. Our capacity factor scores the published seating rather than the exterior measurement for exactly this reason.

Why does the most expensive tub win by such a narrow margin?

Because the composite measures hydrotherapy delivered per dollar committed, not absolute capability. The flagship attains 8.7 and the pipe-flushing Empava attains 8.4, a gap of 0.3 on a ten-point scale, which is well inside the precision of a specification-based model. The flagship leads on jet count, capacity and basin width, but the cheaper tub matches it on feature density and beats several rivals on value. If you want the fullest possible hardware the flagship is the answer; if the marginal jets are not worth roughly a thousand dollars to you, the ranking is telling you they need not be.

Sources & Methodology

Methodology: SHE Smart Soak Score — Formula: (Hydrotherapy Power × 0.40) + (Smart Feature Density × 0.30) + (Therapeutic Value per Dollar × 0.20) + (Capacity Score × 0.10). Factors: Hydrotherapy Power (40%): Published jet count, square-root normalized against the highest count on the roster so a forty-jet chassis does not run away with the ranking, plus a bonus where the listing states a combined water and air system and a further bonus where it states two separately rated pumps. Capped at ten. | Smart Feature Density (30%): A count of the premium features each listing actually publishes, drawn from chromotherapy, a heater, audio, ozone sanitization, panel or preset control, a specialty mode such as pipe flushing or a waterfall filler, combined jet types, and two separately rated pumps. Each is worth 1.25 points on a ten-point scale. | Therapeutic Value per Dollar (20%): Jets delivered per thousand dollars of verified Amazon purchase price, normalized against the strongest ratio on the roster so the best-value chassis scores ten. This factor is deliberately independent of feature count, which is why the cheapest tub here leads it outright. | Capacity Score (10%): Seating as published: a stated two-person chassis scores ten, a flexible one-or-two-person chassis scores 7.5, and a single-bather chassis scores five. Seating dimensions decide this rather than exterior length, because a 71-inch shell can still seat one.

Expert review sources used in this analysis:

1. SmartHomeExplorer aggregates expert review coverage and published manufacturer specifications
2. No first-party product testing was conducted for this guide
3. The most important disclosure on this page is a negative one
4. We checked our registered outlet list against all five products and found no independent editorial review of any of these exact models
5. Bob Vila's whirlpool-tub roundup ranks the Empava 59JT319 corner tub and the Empava 71JT667B alcove tub, both different products from the Empava tubs reviewed here
6. Family Handyman's spa and jacuzzi tub roundup ranks a Woodbridge Andria whirlpool and air combination, a different model from the WOODBRIDGE reviewed here
7. Six Storeys ranks a heated 72-inch WOODBRIDGE whirlpool, again a different model
8. This Old House covers the category and its installation requirements without ranking any product on this roster
9. Those outlets are cited in this guide only for what their own articles say about the category, never as verdicts on our picks
10. The expert-source count on each product card is therefore zero
11. Every jet count, dimension, capacity, electrical rating, warranty term and price in this guide was read directly from the product listing on Amazon on August 31, 2026
12. All five listings showed as in stock and in new condition at that time; the 67-inch Empava showed a single unit remaining, which is worth re-checking before ordering
13. Prices are list prices and change frequently, so check the current figure on Amazon before buying
14. The SHE Smart Soak Score is our own composite and is not attributable to any outlet
15. Its four factors, their weights and the normalization applied to each are published on the metric page and in the methodology block above
16. Factor inputs are published specifications rather than measured results, which is a real limitation of this ranking and the reason no first-party performance claim appears anywhere in this guide
17. This version replaces a roster that recommended a KunMai tub not sold on Amazon
18. That earlier version described the flagship Empava as carrying 65 jets, an ozone sanitization system, wireless audio and a milk-bath mode
19. The listing we verified publishes none of those four features
20. Those claims have been removed rather than restated.
