When you want a deep, hot soak, the tub you pick decides whether that bath feels like a luxury spa or a drafty compromise. Enameled steel bathtubs deliver the solid, heat-retaining feel of cast iron but at a weight you can actually install without reinforcing your floor—and the trick is knowing which one keeps its glossy finish for years, not weeks.
The tub that stands out for most buyers is the American Standard Cambridge Soaking Tub. It gives you 50 gallons of deep water and a finish that buyers report stays chip-free for years without the 300-to-400-pound weight of cast iron. This guide compares three top contenders from American Standard based on published specs and verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Our Picks at a Glance
How To Choose The Best Enameled Steel Bathtub
An enameled steel tub is a steel shell coated in a glossy porcelain finish. It feels solid under you, holds water temperature better than acrylic, and weighs about half of what a cast-iron tub does. That weight difference means you can usually install one without extra floor joists. The main thing to watch for is the quality of the porcelain. A thin coat chips. A thick, well-bonded one lasts for decades.
Capacity and depth
A deeper tub lets you submerge more of your body. Capacities here range from 42 to 60 gallons. If you are tall or want a true soak that covers your shoulders, aim for the higher end. Keep in mind that a deeper tub also holds more water weight, so your water heater’s recovery time (how fast it reheats after a full draw) matters.
Weight and installation
Even though enameled steel is lighter than cast iron, a tub can still run from 89 to 118 pounds. That is manageable for two people to carry, but you still need proper support underneath. A tub that flexes when you step into it will crack its grout and tile over time, so a leveling base and solid subfloor are non-negotiable.
Finish durability and slip resistance
The porcelain finish is what makes the tub easy to clean and resistant to scratches—provided it is applied thickly. Look for a textured floor surface built into the porcelain, not a stick-on mat. That texture prevents slips without needing a separate bath mat. The trade-off is that a textured floor can collect soap residue, which comes off with a monthly gentle cleaner.

In‑Depth Reviews
1. American Standard Cambridge Apron-Front Americast Soaking Tub
Our pick — over 4★ from 200+ verified ratings; the strongest balance of quality and price.
The deep soaker that lets you disappear underwater without needing a structural engineer.
This tub earns its spot because of its 50-gallon capacity and 17.7-inch sidewall height, which is taller than the Princeton models. Owners mention the deep tub prevents water splashing, and The enamel finish stays durable after years with no nicks or cracks.. The integral lumbar support with a beveled headrest means you do not need a separate bath pillow, and the built-in slip-resistant surface (called Stansure, a textured pattern fired into the porcelain) keeps the floor safe without a sticky mat. At 118.1 pounds, it is lighter than cast iron but still feels planted—it does not shift under you.
Americast construction (a steel center layer bonded between polymer and porcelain) retains heat noticeably better than acrylic, according to buyer feedback. The finish is glossy, easy to clean with just a cloth and soap, and resists scratching during normal use. One note: the etched safety bottom can collect dirt over time, but owners say a monthly clean with a gentle abrasive like Bon Ami keeps it looking new. Compared to the Princeton above-floor model, the Cambridge has a thicker porcelain coat that customers note resists chips from plastic bottles.
The real soaker: At 17.7 inches tall and 60 by 32 inches, the Cambridge fits a standard five-foot alcove but gives you an extra two inches of width compared to a typical 30-inch tub—enough to spread your arms without touching the sides. If you want a tub that stays warm, holds you deep, and arrived at reviewers’ doors in flawless condition, start here.
The honest trade-off: The same textured floor that keeps you steady also holds onto soap scum; plan a monthly scrub cycle. And at 118.1 lb, it is relatively heavy for an enameled steel tub—get a helper for moving it into place.
Best for: Anyone who wants a deep, daily soaking tub with proven durability and a premium feel that rivals cast iron without the back-breaking weight. Reach for it if your water heater can handle a 50-gallon fill.
Look elsewhere if: You need ADA compliance or a lower step-over height—the Cambridge sits taller than the Princeton above-floor models.
2. Princeton Americast 60 x 30-Inch Integral Apron Bathtub
The clever drain design that eliminates a common leak point most tubs ignore.
What sets this tub apart is the factory-installed overflow and the integrated drain assembly. That single detail saves you from buying a separate drain kit and removes the risk of an overflow gasket failing inside a finished wall—a repair that requires tearing out tile. As buyers put it: “Very nice tub that is easy to install. The integrated drain saves money and the chances of leaks.” The tub holds 42 gallons of water, which is enough for a comfortable soak without overfilling a smaller water heater, and the steel-reinforced Americast construction gives it a solid, non-flimsy feel. At 89.08 pounds, it is the lightest tub here—easier to carry upstairs than the 118.1-pound Cambridge.
At 26.75 inches wide and 16 inches deep, this Princeton is narrower than the Cambridge—it fits tighter alcoves where you only have 27 or 28 inches to work with. The pre-leveled tub bottom makes positioning easier for a DIY installer; you do not have to shim aggressively to get it flat. The integral three-sided tile flange (a lip that runs along the top edge where the tub meets the wall) helps keep water from seeping behind the walls. The full Stansure slip-resistant floor is built into the porcelain just like the premium Cambridge model, giving you the same underfoot safety. Owners consistently describe it as “good solid construction, durable, nothing flimsy or cheap here,” and the brand backs it with a limited lifetime warranty.
Smart design wins
- Factory-installed overflow and drain stop—one fewer part to buy and install
- At 89.08 pounds it is the lightest tub here, easiest to maneuver into a second-floor bathroom
- Pre-leveled bottom simplifies the installation process for a confident DIY job
What to watch for
- 42-gallon capacity is shallower than the 50- or 60-gallon options—tall bathers won’t fully submerge
- The proprietary drain design means replacement parts are not standard hardware-store items
- Some units have arrived with cosmetic defects in shipping, so inspect carefully before installation
Reach for this if: You want a straightforward drop-in installation with a lower weight for carrying upstairs, and you value the leak-proof confidence from an integrated overflow. Also a great pick for a guest bathroom soak.
Consider something else if: You are a taller person who needs maximum depth to cover your shoulders, or you prefer a universal drain that any plumber can replace.
3. American Standard Princeton Americast Above-Floor Rough-In Bathtub
The biggest capacity in the lineup, designed so you can plumb it without breaking open the subfloor.
With 60 gallons of soaking room, the Princeton above-floor rough-in holds more water than any other tub here. The above-floor design means the drain plumbing runs in a space beneath the tub itself, so you do not have to cut into the floor or move existing drain lines—a serious time-saver during a remodel. It is the only model here that is ADA compliant (Americans with Disabilities Act compliant), with a 14-inch height that makes stepping over the side easier for anyone with limited mobility. The Americast backing insulates the water to keep it warmer longer than a standard enameled steel tub, and the same backing also muffles the sound of shower spray, which owners who also shower in this tub appreciate.
Owners praise the stability, with one noting the tub is “sturdy enough not to bow or deform” under normal use. The finish is a glossy porcelain that cleans easily with a soft cloth and soap. But the buyer consensus is honest about a real trade-off: The porcelain layer chips easily—even a plastic bottle can damage it—and multiple reviewers point out the finish failing quickly.. One owner summarizes: “The finish chipped within a month after plastic bottles were dropped in..” For that reason, this tub demands care—no metal cans, heavy shampoo bottles, or dropped tools. It also flexes slightly when you stand in it to shower, which the lighter construction causes. That flex can crack grout over time unless the tub bed is perfectly supported underneath.
The right fit: If you need an accessible, ADA-compliant tub that holds 60 gallons and lets you route the drain without busting up concrete or floor joists, this Princeton is class-leading. The 14-inch height is genuinely easier to step over for older family members. Stability is its most-praised feature.
The honest heads-up: That porcelain finish is thinner than the Cambridge model—treat it gently. If you are a family with kids who drop toys, or you want a tub that can shrug off bumps without chipping, the Cambridge’s harder finish is a better bet.
Pick this for: An accessible, high-capacity soaker bath where the plumbing is tricky and the bather needs a lower step-in height. The 60-gallon fill is generous enough for a deep soak even for a tall person.
skip it if: You want a finish that can take incidental impacts from dropped bottles, or you prefer a rigid tub that does not flex at all under standing weight.
Understanding the Specs
Americast Construction
Americast is a patented material from American Standard that sandwiches a steel center layer between a polymer backing and a glossy porcelain finish. The steel gives it the rigid feel of cast iron, but the composite backing makes the whole assembly lighter (often by half). It also insulates the water better than bare enameled steel, so your bath stays warm longer. The trade-off is that the porcelain coat is still just a coating. Dropping a hard object on it can chip the finish, especially on thinner applications.
Stansure Slip-Resistant Floor
Stansure is a textured surface baked into the porcelain floor of the tub during manufacturing. It feels a bit like very fine sandpaper. It gives you enough grip that you do not need a suction-mat, but it is not rough enough to be uncomfortable on your feet or back when sitting. It is a permanent part of the porcelain, so it never peels or wears off like an adhesive mat. The trade-off is that the texture can trap soap residue. A monthly cleaning with a mild abrasive powder keeps it slip-free.
Integral Apron and Tile Flange
An integral apron means the front face of the tub is molded as one piece with the rest of the tub—no separate panel to install. The tile flange is a lip that runs along the top edge where the tub meets the wall. It stops water from seeping behind the tub onto the framing. An integral three-sided flange covers the two ends and the back, which makes waterproofing much easier during a tile installation.
Above-Floor Rough-In vs. Standard Drain
A standard tub drain goes through a hole in the subfloor, which means you have to cut flooring material and route pipes in a crawlspace or basement. An above-floor rough-in creates a built-up platform under the tub where the drain runs horizontally and then drops down at the wall. This is useful when you are installing on a concrete slab or when moving the drain location would be expensive. The trade-off is a slightly higher step-up into the tub.
