If you want a bath that actually covers your shoulders, the tubs below are the ones worth your money. Three things on any spec sheet decide the difference: how deep the water sits, how much water the tub holds, and what the shell is made of. Water depth is the number most people skip right past on the listing. It is also the one that decides whether you get a real soak or just a warm sit. Get that number right, match the shell material to how much upkeep you will tolerate, and the rest of the decision falls into place fast.
I’m Mohammad Maruf — the founder and writer behind KitchPrep. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
You will see freestanding acrylic soakers, stone resin models that hold heat for a long time, and a jetted option with air bubbles built in. Each one fits a different bathroom and a different body, so here is the honest rundown of the best bathtub deep soaking tub.
Our Picks at a Glance
How To Choose The Best Bathtub Deep Soaking Tub
A deep soaking tub is not judged by how long it looks on the outside. It is judged by how much water sits around your body once you are in it. Two tubs can both be 59 inches long and give you completely different soaks, because one may be built with a shallow floor and the other with a deep basin that lets water sit past your shoulders. Before you compare anything else, find the tub’s water depth or its gallon capacity — those are the two numbers that tell you how deep the soak really goes.
Water Depth And Gallon Capacity First
Depth is the distance from the tub’s lowest point up to where the water escapes through the overflow. A deeper basin means more of your body is underwater at once. Capacity, measured in gallons, is the companion number — it tells you how much water the tub actually holds when filled. More gallons in a smaller footprint usually means a deeper, more vertical basin. That is exactly what compact Japanese-style tubs do: they trade length for height, so you sit more upright while still getting a full-immersion soak.
Shell Material And Heat Retention
The shell decides how long your water stays warm and how easy the tub is to live with. Acrylic is the lightest and cheapest to move, but thin acrylic loses heat faster unless it is paired with insulation. Stone resin and solid surface shells are much heavier — some cross 300 pounds empty — and their thick walls hold warmth far longer. Solid surface also lets you sand out minor scratches instead of living with them. The trade-off is weight: a heavy stone tub can need floor reinforcement and several people to set in place.
Fit, Installation, And Drain Placement
Measure your door opening and your floor before anything else. A tub that cannot make the turn into your bathroom is useless. Check the packaging height, since some tubs fit through sideways when they will not go through upright. Drain placement matters too — an end drain, a center drain, and an integrated slotted overflow all change where your plumbing has to land. If your drain is already roughed in, match the tub to it rather than the other way around.

In‑Depth Reviews
1. 67″ SYLONWILL Free Standing Tub, cUPC Certified SY6270 (Glossy White)
Our pick — over 4.5★ from 50+ verified ratings; the strongest balance of quality and price.
A 67-inch acrylic soaker with a 10-year no-yellowing finish guarantee
If you are remodeling a main bathroom and you want one tub that does deep soaking without asking you to learn a new maintenance routine, start here. The basin holds 66 gallons, and it is built from 100% new pure PMMA — a high-grade acrylic that the maker guarantees will not yellow for 10 years. That matters in real life: a tub that keeps its glossy white finish still looks like a new install long after the rest of your bathroom has aged around it.
The shell is a multi-layer build, reinforced with resin and fiberglass, which helps the water stay warm and gives the tub real stiffness. What wins people over is the construction — the quality of the build is the thing owners talk about more than anything else, with appearance right behind it and comfort rounding out the list. Buyers describe it as comfortable and spacious, and the finish shrugs off bath salts and oils, so you can use whatever you like in the water. One owner put it plainly: “Completely happy with this tub, comfortable spacious and holds the heat well. I love that salts and oils are not a problem for the finish.”
Under the floor sits a stainless frame with adjustable legs, and the maker rates the load up to 1250 LBS, which means adults are not shifting this tub around mid-soak. It is a substantial 94.8 Lbs empty — noticeably heavier than the 77.2-pound ANZZI and the 64-pound FerdY Bali further down this list, but still a freestanding tub two people can position. The one honest catch is length: at 67 inches it suits bathers from about 5 feet 5 inches up to 6 feet 3 inches, and taller folks report it feels tight. It is also cUPC certified, which is the plumbing code compliance stamp your inspector will look for.
What Buyers Keep Praising
- 66-gallon basin gives a deep, full-immersion soak without eating floor space
- 100% new pure PMMA acrylic with a 10-year no-yellowing guarantee from the maker
- Stainless frame and adjustable legs rated to hold up to 1250 LBS
- Holds heat well and resists salts, oils, and cosmetic products
The Trade-Offs To Weigh
- Taller bathers near 6 feet 3 inches find the 67-inch length snug
- At 94.8 Lbs empty, plan for help getting it through the door
- In-home delivery is worth arranging so it does not sit on a driveway
The pick for: anyone who wants a proven daily soaker with a finish guarantee measured in years, not months.
Look elsewhere if: you are taller than 6 feet 3 inches or your bathroom simply will not take a 67-inch footprint.
2. ANZZI Freestanding Bathtub Acrylic 59 In Flat Bottom Soaking Tub White Mone
A 59-inch soaker with 14.2 inches of water depth and 53 gallons of capacity
Here is the math that makes this tub worth a look: it holds 53 gallons in a body just 59.1 inches long, and that water sits 14.2 inches deep in the basin. Compare that to the 68-gallon WOODBRIDGE 71-inch model above — you are giving up a chunk of capacity, but the ANZZI asks for roughly a foot less wall space. If your bathroom is the reason you cannot have a proper soak, this is the trade that gets you one anyway.
The flat bottom is the detail that separates it from the bowl-shaped freestanding tubs. A flat floor means more of the base sits right against your tile, so the tub feels planted and the interior stays generous in every direction. You can fully submerge in it, and it doubles as a shallow pool for small children — which is exactly how owners describe using it. The glossy white acrylic wipes clean with little effort, and an integrated overflow keeps the water level under control while you fill.
The obvious follow-up: is a 77.2-pound acrylic tub stable enough to trust? Empty, it is light, and the maker’s own guidance is not to sit on the rim. The fix is simple and cheap — set edge spacers along the wall side and give it a proper bead of sealant, and it stops moving. It arrives at a price that sits below every other pick here, and owners say it moves up a staircase without a crew. Crouch down and check the drain stub-out height before you commit, because a flat-bottom tub needs the plumbing to land exactly where the manufacturer’s drawing says.
Where it earns its keep: the compact 59-inch shell, 53 gallons of capacity, and 14.2 inches of depth together deliver a genuine shoulder-deep soak in a bathroom that has no business fitting one.
What to handle on install day: anchoring. Light acrylic and a flat bottom mean it wants edge spacers and sealant to feel rock-solid, especially before anyone steps in.
Reach for this if: space is your hard limit and you still want to submerge completely.
Pass it by if: you want a heavy, immovable tub out of the crate or the included drain hardware matters to you.
3. WOODBRIDGE 71″ Acrylic Freestanding Bathtub, Matte Black B1817-MB
The largest acrylic basin here at 68 gallons, with double-walled insulation that slows heat loss
Go big or go home applies here. This is a 71-inch tub holding 68 gallons — the largest capacity among the acrylic freestanding picks, and a full 28% more water than the 53-gallon ANZZI. It is built from high-gloss black LUCITE acrylic reinforced with ASHLAND resin and fiberglass, and the double-walled construction is the reason the water stays hot longer than the number on the faucet suggests. If your idea of a soak runs 45 minutes, that insulation is doing real work.
The exterior measures 71″ long by 31 1/2″ wide by 28 3/8″ deep, and the gently sloping interior follows your back rather than cutting into it. The floor is finished with a non-slip surface that meets ASTM slip-resistance standards — a category of testing that measures how much traction a wet surface offers — so you are not stepping onto a slick sheet when you climb out. ENDURACLEAN gives you a stain-resistant, scratch-resistant surface that keeps its gloss, and the metal bracket underneath supports up to 1000 LBS.
Two honest notes before you order. First, buyers report that having a plumber come in and do the connection was an unexpected line item, so budget for that labor rather than assuming it is plug-and-play. Second, this tub is heavy construction in the best sense and simply needs a clear path in — measure your door before you fall in love with the matte black finish. Owners name quality, thick walls, and well-considered design as the reasons they picked it, and it ships with a solid brass matte black drain and stainless overflow already in the box.
Why it deserves the top spot on size: 68 gallons across 71 inches is the most soaking water per fill here, and the double-walled shell keeps it warm while you linger.
One honest bit of prep: it is in compliance with CSA B45.5-17 and the Massachusetts Plumbing and Gas Code, and it carries a 1-year limited warranty against material and workmanship defects — read that alongside your installer’s scope so nothing gets missed.
Your pick if: you have the bathroom width and you want the deepest, warmest, most generously sized soak on this list.
Skip past if: your plumbing budget does not include a pro connection call or you need a tub that slides into a compact corner.
4. FerdY Bali 55″ Freestanding Bathtub with Brushed Nickel Drain
A 55-inch tub with 15 inches of water depth and a 64-pound empty weight
Read the FerdY Bali’s soak depth and length side by side and you see the trick: the basin is only 55.12 inches long, but the water sits 15 inches deep. That combination means the tub fills tall rather than wide — more vertical, which is exactly how you get a deep soak in a narrow bathroom. The sloped lumbar support is there to keep your lower back comfortable while you sink in, and the integrated slotted overflow keeps the look clean while still letting the water rise high.
Light weight is one of the reasons this tub gets chosen for upper-floor bathrooms. It weighs 64 pounds empty, which is lighter than both the 77.2-pound ANZZI and the 94.8-pound SYLONWILL, so it can go up a staircase with two people instead of a team. The 100% glossy white acrylic shell is reinforced with fiberglass for durability, resists a wide range of household chemicals and cosmetics, and carries cUPC certification. It also comes with seven drain-stopper finish options sold separately, which lets you match your faucet instead of settling for the included one.
Now the honest part. Size is the biggest topic in FerdY Bali reviews, and it runs mixed — several buyers find it smaller than expected. For a 5-foot-6 bather or shorter, owners describe the fit as perfect; for anyone taller, the FerdY page even suggests trying a tub this size in a showroom before you buy. There is a second point worth planning around: at least one professional installer flagged the included plastic drain seal pipe as something he would not trust and swapped in custom fittings. Neither of those is a dealbreaker if you want a light, compact, budget-friendly soaker — but both are things to decide on before delivery, not after.
The compact-tub case: 15 inches of soak depth in a body that fits a space under five feet long, at 64 pounds empty, is the most space-efficient way to get a full soak on this list.
Who this is not for: bathers well over 5 feet 6 inches, or anyone who wants to skip the drain-hardware discussion at installation.
Built for: smaller bathrooms and shorter bathers who want their water to reach the shoulders without giving up floor space.
Think twice if: you are tall or you plan on using the factory drain kit as-is without a plumber’s input.
5. Fine Fixtures 72″ Alcove Soaking Bathtub with Integral Apron BTA105-L
A 76-gallon alcove tub with a pre-fixed tile flange and left-hand drain
If your bathroom has three walls and a tub-shaped alcove, this is the tub built for that hole. An alcove tub keeps the water contained on three sides, which means splashes stay in the tub rather than finding the floor, and the pre-fixed tile flange keeps water from getting behind the wall where it would rot.
The construction is durable acrylic with fiberglass reinforcement, finished in a glossy white that resists cracking, chipping, and damage from salts and oils. A built-in ledge gives you a place to set toiletries and towels instead of balancing them on the rim. The sloped lumbar support is there for the same reason as every other pick in this list — to keep your back comfortable — and the profile keeps the tub space-saving even at 72 inches, which is exactly what you want in a guest or family bathroom.
The catch here is that this is not a freestanding tub. It installs into an alcove or drop-in surround, so the finish job around it needs to be planned before the tub goes in, and the drain must be rough-plumbed on the left-hand side. Quality is what carries this pick — owners consistently describe the workmanship as excellent, and one called it the best alcove tub available. A couple of notes from the review pages: the step-in can feel slightly high for shorter users, and packaging has occasionally left debris on a driveway instead of at the door. Both are minor, but both are things to arrange in advance.
The case for it: 76 gallons is the deepest fill on this list, and the alcove format gives you that capacity with splash protection built in on three sides.
The catch worth reading: it is a recessed install, not a freestanding tub — so plan the tile surround and left-hand drain rough-in before it arrives.
Made for: anyone replacing an old alcove tub who wants the biggest soak volume without moving walls.
Not the one if: you want a freestanding focal point for the middle of the room or you need the drain on the right.
6. WOODBRIDGE 55″ Stone Resin Freestanding Soaking Tub, Matte White B0043
A one-inch-thick solid surface soaker whose scratches sand out
This is the tub for the bather who wants the water hot for the whole bath and does not care that furniture-grade weight comes with it. It is molded from solid surface stone resin, one full inch thick, and that mass is why the rim, walls, and base all stay warm against your skin while you soak. The water sits 15 inches deep, and the basin holds 65 gallons — a deep fill in a compact 55-1/8 by 30-3/4 footprint, which puts it right between the compact acrylic tubs and the oversized 71-inch models.
The reason this tub earns its premium is the surface itself. Solid surface is not acrylic, and that changes maintenance completely: minor scratches and surface marks can be sanded out instead of lived with. The surface is non-porous, which keeps water and soap from absorbing into the material — you wipe it down and it is done. And the stone resin finish has a warm, silky feel that is a different experience from cool acrylic against your skin. Add a 1.9-inch large-diameter drain with a removable pop-up on copper and silicone seals, and daily use stays simple. Note that the drain pipe itself is sold separately.
Two things to know honestly. The overflow is on the small side — reviewers with heavily filled tubs say drainage is slow and can take a while, which matters more if you have small children who want to fill and empty repeatedly. And second, the back slope will not suit every body; some bathers find it comfortable, others find it too upright for a long reclining soak. If neither of those is a problem, what you get is a heavy, warm-feeling, repairable tub that a buyer compared to a much more expensive local showroom model.
Why the price tag: one-inch-thick solid surface with a sandable finish is a different material class from thin acrylic — you are paying for the warmth and the option to renew the surface, not just the shape.
The follow-up question: drainage speed. Plan for the slow overflow if you have multiple bathers or children filling and emptying the tub back to back.
The one for you if: you want the warmest, most durable surface and you are willing to plan for a heavier delivery and a slower drain.
Look past it if: you need fast emptying cycles or a backrest shaped for long reclining soaks.
7. MEDUNJESS 51″ Japanese Soaking Tub, Stone Resin Freestanding
A 51-inch upright Japanese-style soaker that holds 78 gallons
This is a different kind of deep soak, and it is worth understanding the difference before you compare its 51.18-inch length to anything else on this list. A Japanese soaking tub is tall and vertical rather than long and reclining, and the MEDUNJESS is a good example: just over 51 inches long but built to hold 78 gallons — the largest fill by capacity on this entire list — so you sit upright with water around your shoulders and your head clear, instead of sliding flat and losing depth to the floor. If you have ever wanted to soak without leaning back and getting your hair wet, this is your shape.
The material is what earns the premium price. It is a handmade solid surface blend of 60% organic rock rich in aluminum and 40% US-made resin, molded as one smooth piece. That means no joints or seams around the rim, and the non-porous surface resists stains, scratches, and chipping. The finish is a no-slip matte with a silky soft touch, and the maker says the surface will not fade or yellow even after long-term exposure to light. It also stays warmer than thin acrylic, and the ergonomic contouring gives head and lumbar support so you can stay in a long time without shifting.
The catch is weight and delivery. At 280 pounds empty, this is one of the heaviest picks here, and owners describe moving it with several people and special equipment. It also arrives as a large item that has occasionally shown up damaged in transit — the company handles replacements, but allow time for that possibility. Because it is this heavy, the floor under it and the strength of your bathroom structure matter, and the maker does not include a faucet. Those are the trade-offs you accept for an upright, smooth stone soak.
What justifies the spend: one-piece handmade stone construction with no seams, a no-fade matte finish, 78 gallons of upright soaking capacity, and the heat retention that only heavy stone delivers.
Plan before you buy: at 280 pounds empty this needs floor evaluation and a real delivery crew; it also ships without a faucet.
Reach for this if: you want an upright, smooth, warm stone soak and you have the floor and space to support something this substantial.
skip it if: your bathroom is upper-floor with regular joists and you are not prepared to reinforce or bring in a lifting crew.
8. Empava 59″ Freestanding Air Jetted Bathtub with Micro Bubble Hydrotherapy
The only air-jetted pick here, with 48 air jets and a 21-inch waterline
This is the only pick on the list with a built-in air massage, and if that is what you are after, it belongs at the top of your shortlist. The tub has 48 precision air-pinhole jets driven by a 0.5 HP air pump — the pump pushes air through those tiny holes to fill the water with thousands of warm bubbles. The result is a gentle, full-body, spa-style soak at home. It also offers 21 inches of water depth, which lets you submerge up to your shoulders, the deepest waterline of any tub here.
The build is designed around lasting wet-area performance. The shell is 100% sanitary-grade acrylic reinforced with fiberglass and supported by a stainless-steel frame with a weight capacity of up to 440 lbs. The floor surface is textured and slip-resistant, and the interior sits on a molded seat. It includes a chrome waterfall faucet, drain, ergonomic control knobs, a showerhead with adjustable spray modes, and a 47-inch retractable stainless-steel hose. The motor is UL certified — a safety standard for electrical components — and the tub comes with a pre-installed 120V GFCI power cord, which is the kind of grounded, trip-protected outlet a tub with a pump needs. Empava backs it with a 3-year US-based limited warranty on parts like the jets and tub body.
Drainage and support are the two things buyers flag most on this model — installation can be the weak link, and some owners say the built-in drain runs slowly and the flexible drain hose can be fussy to route. If your drain has to make two sharp bends, the flex hose may not have enough pitch to flow. Plan the plumbing location carefully or have a pro confirm it before delivery. On the bright side, what wins people over is the look — a pure-white finish many buyers describe as more attractive than other tubs they shopped — and the feeling of having a full hot tub in a small bathroom. A few minor hardware nits, like the number of finish options, are note but easy to work around.
Where it shines: 21-inch soaking depth — the deepest waterline here — plus 48 air jets and double-walled insulation for warm, bubbling soaks without frequent refills.
The install reality: plan the drain location before the tub arrives, and clear space for a professional to connect it — a straight, well-pitched drain run keeps the flex hose working the way it should.
Built for: anyone who wants a jetted, bubbling spa soak in a small footprint with the deepest waterline on the list.
pass on it if: you want a simple gravity-fed drain with zero pump maintenance or you are unwilling to plan the plumbing before delivery.
Understanding the Specs
Water Depth vs. Tub Length
These are two different numbers, and it helps to think of them separately. Tub length tells you how much wall or floor the tub will occupy. Water depth, given in inches, tells you how high the water rises in the basin once you are in it. You can have a long tub that only gives a shallow fill, or a shorter tub that fills very deep. When you want a real soak, prioritize the depth number and the gallon capacity, then check that the length fits your space. A tub that holds more gallons in a smaller footprint usually means a taller, more vertical basin — which is the same idea behind Japanese-style soaking tubs.
Shell Material And Warmth
The material determines three things: how long your water stays hot, how much the tub weighs, and how easy it is to keep clean. Acrylic is the lightest and cheapest to move, but a thin acrylic shell loses heat faster unless the maker adds fiberglass reinforcement or a double-walled design. Stone resin and solid surface are denser and heavier, and their thick walls hold warmth noticeably longer — which is why a heavy tub often feels like the water stays hot all the way through a long bath. Some solid surface shells can also be sanded to refresh the surface, unlike acrylic, where a deep scratch usually stays.
Capacity In Gallons
Capacity is listed in gallons, and it tells you how much water the tub actually holds at a comfortable fill. Larger capacity generally means a longer or deeper soak, but it also means more water to heat and more weight to support when the tub is full. Use it as a comparison tool: two tubs of similar length with different gallon ratings are built with different interior shapes, and the higher number usually has a roomier or deeper basin. Match the capacity to your water heater’s ability to refill after the tub drains, and check that your floor can carry a filled tub’s weight — especially with heavy stone models.

Final Thoughts: The Verdict
For most bathrooms, the deep soaking champion on this list is the 67″ SYLONWILL Freestanding Tub because it combines 66 gallons of capacity, a 10-year no-yellowing finish guarantee, and a stainless frame rated to 1250 LBS — a complete package whether you are remodeling or replacing. If capacity and warmth are your top priorities and your bathroom has the room, the 71″ WOODBRIDGE B1817-MB is the one to order. And if you want the deepest waterline with an air massage built in, the 59″ Empava Air Jetted Bathtub with its 48 jets and 21-inch soak is the choice for you. Whichever you pick, match the tub to your door opening and your rough-in drain first — that decision saves more hassle than any finish option on the list.
