Small Walk-in Tubs

Compare our picks for small walk-in tubs

Our research pointed to these three small walk-in tub companies as the strongest options on the market.

Here’s how they compare:

Small walk-in tubs overview

Any tub under 48 inches in length qualifies as a compact model, according to John Salvatore Gelfusa, president and CEO of HomeWorks CGO Inc, a bathroom remodeling company in Chesterfield, Michigan.

Small walk-in tubs make the most sense in bathrooms under 60 inches wide. Gelfusa noted that a typical condo bathroom measures around 48 by 84 inches, and in that kind of layout, a compact tub is often the only practical option.

These smaller tubs are a natural fit for:

• Seniors aging in place in condos, townhomes or smaller homes
• Petite individuals who find full-size tubs uncomfortable
• Mobile homeowners working with limited square footage

They cost less to buy and less to install than their full-size counterparts. Most compact walk-in tubs run between $2,000 and $5,000, while standard models start around $5,000. And because the installation is less involved, that bill usually comes in lower, too.

Safety-wise, you can expect the basics on most models — grab bars, non-slip flooring, low step-in thresholds and controls you don’t have to reach far for. Where small tubs give something up is legroom. A shorter tub puts you in a more upright position, which taller bathers may notice on a long soak.

Small walk-in tub sizes

Small walk-in tubs range from about 26 to 32 inches wide and 40 to 48 inches long. That’s at least a foot shorter than a standard 60-inch alcove tub — useful context if you’re retrofitting an existing bathroom.

Here’s how the main size categories break down:

One thing people often overlook is interior seat width. In a compact tub, most models measure around 21.5 inches across. But narrower configurations like the cube and mini can feel cramped once you’re seated, so confirm interior measurements before purchasing.

Seat width isn’t the only comfort factor. Shorter tubs also put you in a more upright position, which can wear on the lower back during a longer soak — something taller bathers feel more than most. That’s partly why many small models are built deeper than they are wide, with soaking depths of 20 inches or more, giving you a full-immersion bath even in a tight space.

Did you know? If you’re replacing an existing shower stall, a 36-by-36-inch cube or a 28-by-40-inch small model will often slide right in without major structural changes.

Small walk-in tub features

The most important feature on any walk-in tub is the step-in threshold, according to Patrick Fee, co-owner of Mr. Drain, a Sacramento, California-based plumbing company. “It’ll generally be two to four inches high,” he said. “This feature makes the tub much easier for people with mobility or stability issues to get in and out of, while still getting the benefits of a soaking bath.”

Beyond the threshold, Fee recommended looking for these features:

• Non-slip surfaces on the floor and seating to reduce fall risk on wet surfaces
• Anti-scalding plumbing mechanisms that automatically limit water temperature
• Leak-proof door seals to prevent water from getting out while the tub fills
• ADA-compliant grab bars positioned for stability during entry, seating and exit
• Handheld showerhead for controlled, seated washing
• Fast-drain system to minimize time spent waiting in an empty tub

Door configuration is one of the more overlooked decisions when shopping for a compact tub.

Inswing doors are the most common and work well in compact spaces since water pressure helps keep them sealed. However, Fee noted that inswing doors can be tricky to close if you have longer legs, so test before committing. Outswing doors free up interior legroom and are easier for wheelchair users to use. U-shaped doors are another option, designed specifically for tighter spaces and easier maneuvering.

Beyond the door, the choice between a soaking tub and a hydrotherapy model shapes the whole bathing experience. Soaking tubs offer a deep, comfortable bath without extras, while hydrotherapy models add air jets, water jets or both to target muscle pain and improve circulation. Those managing chronic pain, arthritis or poor circulation may get more out of a hydrotherapy model.

Tip: Fast-fill faucets and quick-drain systems reduce the time you spend sitting in an empty tub. Since you enter before the water fills and wait inside while it drains, a tub that moves water quickly makes the whole experience more comfortable.

Small walk-in tub installation

Most compact walk-in tub installations wrap up in a day. But “it may take two days if the project needs more work,” said Fee. The tub itself is usually narrow enough to fit through a standard household doorway, though door frames may need temporary removal in tighter hallways.

Before work begins, clear the bathroom and remove the existing tub or shower. A professional should also check the subfloor and walls for water damage or anything structural that could complicate the job. In most cases, a small tub can drop into the same footprint as an existing bathtub or shower.

The installation itself typically involves:

• Plumbing modifications to align the drain and connect the water supply
• A dedicated 20-amp, 120-volt GFCI outlet for any jets, heaters or air blowers
• A level, structurally sound floor that can support the tub, water and user
• At least 30 inches of clear floor space in front of the tub
• Silicone sealing around the tub once it’s set, plus filler panels if needed

Generally, professional installation costs $1,500 to $10,000, depending on the project’s complexity. Jobs that require drain relocation, electrical upgrades or tile work will land at the higher end of that range.
