For most households, a mid-range acrylic tub such as the Woodbridge 67-inch freestanding or a 60-inch alcove model from Kingston Brass or Fine Fixtures is the practical choice, because acrylic is light, easy to install and widely available. Choose enameled cast iron such as the Kohler Entity if heat retention and a long lifespan matter more than weight, choose American Standard’s Americast if you want cast-iron-like warmth at a lighter weight, and choose a compact freestanding tub like the FerdY Bali 55-inch for a small bathroom. This guide compares those options using maker specs and outlet reviews, and covers fit, floor load and warranties.

View on AmazonChoose the Tub Type First
- Alcove. Fits in a three-wall recess and is the standard replacement for a tub-shower combo. Usually the simplest and most affordable to install.
- Freestanding. Stands on its own and needs floor space around it, plus floor-mounted or wall-mounted plumbing. Looks dramatic but costs more to install.
- Drop-in or undermount. Set into a deck or surround. Needs carpentry and tile work.
- Walk-in. Has a low threshold and a door, which can help with mobility. Typically requires more space and more plumbing and electrical work.
Materials Compared
Acrylic
The most common modern material. Outlets describe it as lightweight, durable and easy to clean, and scratches can often be repaired. Heat retention is moderate. Surface warranties of five to ten years are typical, but they vary by maker.
Enameled cast iron
Holds heat longest of any tub material, and a roundup reports a weight of 300 to 500 pounds. That weight means you should confirm the floor can support it, ideally with a contractor. Enamel quality can vary between makers, so inspect the tub on delivery. Kohler states a lifetime limited warranty on its enameled cast iron, per a 2026 roundup.
Americast and composites
American Standard’s Americast is marketed as having cast-iron-like heat retention at about 118 pounds, versus 300 to 400 pounds for true cast iron, per one roundup. It may develop hairline enamel crazing sooner than true cast iron, and the maker’s stated warranty is around ten years.
The Picks in More Detail
Woodbridge 67-inch Acrylic Freestanding
This Old House picked it as the best overall. It uses acrylic with fiberglass and resin reinforcement, a double-wall construction for heat retention, a non-slip surface and a chrome drain and overflow. Caveats: it needs a spacious bathroom, some buyers report shipping damage, and a 2026 roundup lists a short limited warranty compared with Kohler or American Standard.
Kingston Brass Aqua Eden 60-inch
A standard 60-inch alcove tub with an integrated apron and deep soaking depth. Plan for the drain kit being sold separately, and note that the surface scratches more readily than some alternatives.
Fine Fixtures 60-inch
Adds a pre-installed tile flange, sloped lumbar support and a storage ledge, but at a higher price than comparable alcove tubs and with occasional shipping damage reports.
FerdY Bali 55-inch
A compact freestanding tub for smaller rooms. Taller people may find it short, and cracking or shipping damage has been reported occasionally.
Kohler and American Standard
A 2026 brand ranking by a tub maker puts Kohler first for range and parts availability. Kohler, American Standard, TOTO and Gerber are noted for broad parts availability and consistent warranty coverage. Premium acrylic freestanding models such as the Kohler Stargaze sit at the high end.
Fit, Size and Installation Notes
- Measure the alcove. A 60-inch tub needs a recess close to that length. Alcove tubs come in left-hand and right-hand drain versions, so match your plumbing.
- Doorways and stairs. Cast iron and large freestanding tubs may not fit through tight doors or stairwells.
- Floor load. A filled tub with a bather is very heavy. Have a contractor check the structure, especially for cast iron.
- Faucets and drains. Freestanding tubs need compatible floor-mounted or wall-mounted faucets, and drain kits are not always included.
- Whirlpool and air-jet tubs. Need a dedicated electrical circuit. Hire a licensed electrician and plumber, and follow the manual.
Care and Warranty Notes
Clean acrylic with non-abrasive cleaners, as abrasive pads can scratch the surface. Follow the maker’s instructions for any chemical cleaners. Read the warranty carefully, since coverage periods differ widely and may exclude damage from improper installation.
Pick X If… Decision Table
| Pick this | If you want |
|---|---|
| Woodbridge 67-inch | A freestanding soaking tub without a premium price |
| Kingston Brass or Fine Fixtures 60-inch | A straightforward alcove replacement |
| FerdY Bali | A small footprint |
| Kohler Entity cast iron | Heat retention and longevity, with a floor that can carry it |
| American Standard Americast | Cast-iron-like warmth at a lighter weight |
| ANZZI walk-in | Easier entry and jets, with professional installation |
Budget Tiers
Budget acrylic tubs cover the basics but may carry shorter warranties and thinner finishes. Mid-range acrylic and Americast models balance warmth, weight and warranty. The premium tier includes enameled cast iron and designer acrylic models from Kohler, where you pay for finish, longevity and warranty coverage.
Alternatives Worth Considering
- Fiberglass tubs. The lowest-cost option, though less durable than acrylic.
- Stone resin freestanding tubs. A weighty, premium look with good heat retention.
- Walk-in showers. If you rarely soak, converting to a shower may suit your space better.
Common Buying Mistakes
Buyers often choose a tub for looks and only later discover it does not fit the room. Measure the alcove, the doorways and the path the tub will travel, and confirm the drain position. Another mistake is overlooking the floor: a large freestanding tub full of water and a bather is very heavy, and cast iron adds hundreds of pounds before any water goes in.
It is also easy to underestimate installation. Freestanding tubs may need floor-mounted plumbing, alcove tubs need a proper support bed or frame, and jetted models need a dedicated electrical connection. Hire licensed professionals where required and follow the maker’s instructions to protect the warranty.
Quick Checklist Before You Buy
- Measure the alcove or floor space, and note the drain side.
- Read the maker’s stated dimensions, capacity and weight.
- Decide on material: acrylic for weight and cost, cast iron for heat retention, Americast for a middle path.
- Read the warranty terms, including what is excluded.
- Plan the faucet and drain kit, which may be sold separately.
- Inspect the tub on delivery and photograph any damage.
Compare capacity with your water heater. A deep 60-gallon tub can use more hot water than a smaller heater supplies, so a compact tub may suit a small household better. For accessibility needs, ask a professional about walk-in designs and grab bars.
Frequently Asked Questions
Which bathtub material is best?
It depends on your priorities. Acrylic is light and affordable, cast iron holds heat longest and lasts, and composites like Americast sit between them. Weight, budget and floor structure usually decide it.
How big is a standard bathtub?
Many alcove tubs are about 60 inches long and 30 inches wide, as the examples above show. Freestanding tubs range from compact 55-inch models to 67 inches or more.
Can my floor hold a cast iron tub?
Cast iron tubs can weigh 300 to 500 pounds empty, so the floor must be assessed. Ask a contractor or structural professional before buying.
Do acrylic tubs scratch easily?
Acrylic can scratch, but minor scratches can often be repaired, according to roundups. Use non-abrasive cleaners to reduce wear.
Are freestanding tubs harder to install?
They often need extra plumbing work and compatible faucets. Because the drain and supply lines may need to run through the floor, plan with a licensed plumber.
How long should a tub warranty be?
Warranties vary. A 2026 roundup reports a lifetime limited warranty on Kohler enameled cast iron, about ten years for Americast and shorter terms for many acrylic tubs. Read the terms for what is covered.
