A jetted tub earns its price only when the jets hit your back and legs and the water stays hot for a full 20-minute soak. So here is the short answer up front: the Empava 48″ Air Jetted Japanese Soaking Tub is the pick to beat for most bathrooms, the two 60-inch Woodbridge alcove whirlpools are the smart buys if you want a built-in look with a heater, and the big 72-inch Woodbridge freestanding tubs are for anyone who wants to stretch out fully. The rest of this page explains which tub fits your alcove width, drain side, and soaking depth.

A jetted tub is a permanent fixture bolted to your floor and drain line, so a wrong pick means re-plumbing a finished wall. Size, drain side, jet count, and heater behavior decide whether your soak feels like a spa or a chore, and this guide walks you through bathtub with jets.
Our Picks at a Glance
How To Choose The Best Bathtub With Jets
Before you compare jet counts, nail down three measurements. Measure your alcove or floor space, note which wall your drain plumbing sits on, and check how much power you can run to the tub. Alcove width, drain side, and available amperage rule out more tubs than any jet count.
Fit Beats Features Every Time
A tub that misses your alcove opening by an inch is worthless, no matter how many jets it has. Freestanding tubs need clearance on at least one side, while alcove tubs slot between three walls and need a tiling flange to keep water out of the wall cavity. Check both the exterior footprint and the interior bathing well, because a roomy shell can still have a cramped seat.
Water Jets vs Air Bubbles
Water jets push warmed water at your muscles for a firm massage. Air jets push thousands of tiny bubbles for a softer, floatier feel. Many of the larger tubs here run both systems in one shell, which gives you the firm pressure and the gentle fizz without choosing between them.
The Heater Question
An inline heater keeps the water at temperature while the pump runs, so you are not draining hot water mid-soak. For a 30-minute soak, an inline heater is the first feature worth paying for.

In‑Depth Reviews
1. Empava Air Jetted Japanese Soaking Tub, 48″ Freestanding Tub
Our pick — over 4★ from 350+ verified ratings; the strongest balance of quality and price.
The compact freestanding tub that lets you sink to your shoulders without eating your whole bathroom
If your bathroom is small but you still want to soak properly, this is the tub that solves that exact problem. The 48 air jets (small holes in the tub floor that push thousands of warm bubbles up through the water) run off a 400-watt motor, so it is a gentle, floaty massage rather than a hard pressure pummel. Because the jets are air-based, there is no pump constantly sucking and recirculating your water — the soak stays quiet and the water stays put.
The shape is what sells it. A built-in seat lets you sit down and still submerge to shoulder level, which is unusual in a tub this compact — you are not folded up with your knees at your chin. The interior basin measures 33.5″ long by 17.72″ wide, and the soaking depth is 21″. At 55 gallons total capacity, that is a genuinely deep soak, and it compares directly to the Woodbridge alcove tubs at 58 gallons, so you are not giving up much water volume to get the smaller footprint.
The trade-off is the plumbing. The included flex hose fits a 1.5-inch drain, but the drawing shows a 2-inch connection, and the drain has to land in exactly the right spot — the hose will not tolerate two 90-degree bends. Plan the drain location before you order, and budget for a real plumber. This is not a tub you drop in on a Saturday afternoon by yourself.
What owners are happiest about
- The appearance is what wins people over most — the pure white, clean, curved finish draws far and away the most praise, and the “gorgeous curved shape” keeps coming up.
- It fits where a big tub cannot: “Fits 5’4″ body fully, retains heat well, small footprint.”
- The value angle lands hard for a freestanding jetted tub at this size.
- At 100 pounds it is 3 pounds lighter than the 103-pound Woodbridge 60-inch alcove tub — meaningful if you are moving it into place with two people.
Where it will test your patience
- The drain spec mismatch is the recurring headache — the flex hose fits a 1.5-inch drain while the drawing shows 2 inches.
- Drainage gets the most negative feedback of any aspect, so get the floor connection right the first time.
- If you plan two tight 90-degree bends in the drain run, this hose will not cooperate.
Reach for this if: you have a tight bathroom or a corner nook, you want deep shoulder soaking rather than a wide tub, and you are fine hiring a plumber to land the drain correctly.
Look elsewhere if: you want a tub that fills an entire three-wall alcove with a longer bathing well — the Woodbridge 60-inch models below run 60 inches long to this tub’s 47.24 inches.
2. WOODBRIDGE 60″ x 30″ Alcove Acrylic Rectangular Whirlpool Heated Jetted Tub, Right Drain, BS666-R-CH01
A triple-wall alcove whirlpool with a heater that keeps the water hot while the pump runs
This is the tub for a bathroom where the walls already frame a tub bay and you want to keep the built-in look. It drops into a three-sided alcove, and the included tiling flange locks the edges against the walls so splash water cannot creep behind the tub. Across the whole shell you get 3 small jets and 6 large jets, and every one of them adjusts to whatever angle your back wants. That angled-jet freedom matters more than raw count — a fixed jet that misses your shoulders is just decoration.
The heater is the real headline. It taps in at 100°F (38°C), switches on automatically with the pump, and cuts out once the water reaches temperature, so a long soak does not slowly go cold on you. Under the water, 7-color LED lighting runs for chromotherapy, and the shell itself is high-gloss LUCITE acrylic reinforced with ASHLAND resin and fiberglass rather than a thin, hollow-feeling plastic.
Owners consistently describe the build as solid and the setup as manageable rather than brutal — buyers report the install is roughly a 6 to 7 out of 10 and “needs 2 people.” The wiring is the part you cannot skip: this tub wants two separate 110-120V, 15-amp GFCI breakers, one for the jets and one for the heater. If your panel is already crowded, that is a real cost to price in before the tub ever arrives.
Drain side matters: this is the right-drain version, so the plumbing needs to come up on the right. Get that backwards and you are re-plumbing a wall — the sister model below moves the drain to the left for exactly that reason.
Room to stretch: the interior bathing well runs 54.5 inches long and 24 inches wide, which is genuinely generous for a 60-inch shell, and the 58-gallon capacity edges past the 55-gallon Empava 48-inch freestanding tub in the same tier.
Go with this one: you have a three-wall alcove, your drain comes in on the right, and you want an in-wall heater doing the work so your soak never cools off.
Think twice if: your plumbing runs up on the left, or you cannot free up two separate 15-amp breakers.
3. WOODBRIDGE 60″ x 30″ Alcove Acrylic Rectangular Whirlpool Heated Jetted Tub, Left Drain, BS428-L-CH01
Same whirlpool hardware as the right-drain tub, flipped for bathrooms plumbed on the left
The only meaningful difference between this tub and the one above is where the drain sits — here it is on the left. That single detail decides whether the tub installs cleanly or forces a plumber to reroute pipe through a finished wall. The rest of the package is familiar: 3 small jets and 6 large jets with adjustable angles, an inline heater that holds 100°F (38°C) and shuts off at temperature, 7-color LED chromotherapy, and a non-slip bottom built to ASTM standards.
Owners mostly rave about the overall quality, and the jetting is the one thing they cannot agree on — some love the strong action, while a few wish the flow could be pushed harder. That is a fair expectation to set going in: the massaging is effective but not aggressive. Because the 60-inch shell is compact, a shorter bather loves it while anyone taller should measure their shoulders against the seating before committing.
The controls are the honest quirk. The touch buttons sit inside the tub, so splashing water can trip them accidentally — a couple of people suggest a different placement would help. It is a design nit, not a defect, and it does not change how well the tub soaks you.
Length reality check: this 60-inch tub exactly fills a 60-inch gap, and owners note they had to trim 2x4s to make it fit flush — so measure your finished opening, not your rough framing, before you cut anything.
Against its twin: it carries the same 9 adjustable jets and the same heater as the right-drain model, but the left-side drain is the whole point — pick by where your plumbing lives, not by spec sheet.
Pick this one: your existing plumbing surfaces on the left wall and you want the proven Woodbridge whirlpool package without reworking drains.
Step away if: you want a ferocious jet massage — the flow here is controlled and relaxing rather than a high-pressure pummel.
Understanding the Specs
Jet Systems: Water vs Air
Water jets (also called whirlpool jets) draw water in and shoot it back out at pressure — that is the firm, kneading massage you feel against a muscle. Air jets push air bubbles up through ports in the floor for a lighter, floating sensation. Tubs that carry both let you switch between firm pressure and soft fizz, and the biggest freestanding models here run both systems at once. A model like the ANZZI walk-in runs 10 whirlpool jets alongside 18 air jets for that dual feel.
Capacity, Depth, And Drain Side
Capacity in gallons tells you how much water the shell holds, and soaking depth tells you how high the water climbs on your body — both matter more than overall tub length for how the soak actually feels. Drain side (left, right, or center) is a fit decision, not a preference, because it has to line up with the plumbing already hiding behind your wall. The ANZZI walk-in, for example, holds 93.79 gallons, far more than the compact 55-gallon Empava freestanding tub, so size and water volume are two separate numbers to check.

Final Thoughts: The Verdict
For most bathrooms, the bathtub with jets winner is the Empava 48″ Air Jetted Japanese Soaking Tub, because it delivers genuine shoulder-deep soaking and 48 air jets in a footprint small enough for a tight space — the best all-round fit for the money. If you have a three-wall alcove and want an inline heater keeping the water hot, the WOODBRIDGE 60″ Right-Drain Whirlpool is the one to grab; if your plumbing sits on the left, its Left-Drain twin slots right in. And for a long soak with room to stretch out fully, the WOODBRIDGE 72″ Whirlpool & Air with Faucet is the one worth reaching for.
