The short version: A bath lift is the cheaper path to safe tub bathing, $300-$700 versus $7,000-$25,000 for a walk-in tub. Buy the Drive Medical Bellavita ($300) for most users. The Drive Medical Sonaris adds backrest recline for $450. Skip lifts under $200, battery and motor reliability are poor.

When a bath lift is the right tool

A bath lift sits in your existing bathtub. The user sits down on it (the seat is at tub-rim height), the unit slowly lowers them into the water using a battery-powered motor, and lifts them back out after the bath. No tub remodel. No plumbing. Portable between bathrooms.

This is the right tool when:

  • The user wants hot soaks for arthritis or chronic pain (a walk-in shower doesn’t help here).
  • A walk-in tub remodel is too expensive or disruptive.
  • The user shares the bathroom with others who use the tub normally.
  • The user travels and wants to bring a bathing aid.

It’s not the right tool when the user can’t sit safely on a tub-rim-height surface (a transfer bench addresses that case).

How we tested

We bought four bath lifts priced from $180 to $550. Each was tested for:

  • Lift cycles per charge: at least 5 should be possible.
  • Lowest seat position: should reach 2-3 inches above tub bottom.
  • Suction-cup grip: base must hold on porcelain and fiberglass without slipping.
  • Control reliability: handheld controls must respond consistently for 100 cycles.
  • Battery indicator accuracy: does the low-battery warning fire with enough margin?

Two passed every test. One passed lift cycles but failed grip on fiberglass. One failed multiple tests, the $180 import.

Our picks

1. Drive Medical Bellavita Bath Lift: best overall

The Bellavita is the most-used bath lift in US occupational therapy clinics. About $300. 308-pound capacity. Reaches 2.3 inches from the tub bottom at the lowest position. Folds nearly flat for storage.

Why we pick it:

  • 308-pound capacity covers most users
  • Reaches 2.3 inches, meaningful soaking depth
  • Folds to about 4 inches thick for storage
  • Suction cups grip both porcelain and fiberglass tubs
  • IPX7-rated control, fully waterproof
  • Replacement battery available, $90

Where it falls short: no backrest recline. The seat back is fixed at about 95 degrees.

2. Drive Medical Sonaris Bath Lift: best for users wanting backrest recline

The Sonaris is the upgrade Bellavita with a power-reclining backrest. Same 308-pound capacity. About $450.

Why we pick it:

  • Backrest reclines from upright to about 35 degrees for full soaking
  • Same 308-pound capacity as the Bellavita
  • Same waterproof control
  • Same suction-cup base reliability

Where it falls short: higher price; more parts means slightly higher long-term failure risk.

3. Mangar Bathing Cushion: air-powered, alternative for cold-prone users

The Mangar is an air-powered alternative to electric bath lifts. A small air pump sits next to the tub; the cushion inflates to lower the user, deflates to raise. About $1,200, much pricier, and we recommend it only for users who fear electric devices in water or have already had a bad experience with electric lifts.

What we don’t recommend

Bath lifts under $200. Battery life is poor (often 2-3 cycles per charge), the motor strains under load, and the control reliability degrades fast. Spending an extra $100 to get the Bellavita is one of the best dollars-for-safety trades in the senior bathroom market.

Lifts without IPX7-rated controls. The control gets wet during normal use; non-waterproof controls fail in 6-12 months.

Install and setup

Bath lifts are portable, not installed. Setup:

  1. Place the lift in the tub at the high (rim-level) position.
  2. Press the suction-cup base firmly to the tub bottom.
  3. Confirm the unit doesn’t shift under 30 pounds of side push.
  4. Charge the battery overnight before first use.

The user sits on the rim-height seat, presses a button, and the lift lowers them. After bathing, they press the up button. Total cycle time is 60-90 seconds in each direction.

For first-time users, an occupational therapist’s in-home eval is worth the $50-$150 to confirm safe technique. See how to find a CAPS-certified specialist, most CAPS contractors can refer to a local OT.

Battery life and replacement

Most bath lifts go through 2-3 batteries over their useful life. Replace at the first sign of degradation (fewer than 4 cycles per full charge). Batteries cost $80-$150 depending on model. Don’t try to extend battery life past 3 years, the failure mode is “lift won’t raise user out of water,” which is the worst possible failure.

What to do next

If you want safe tub bathing without a remodel: buy the Drive Medical Bellavita ($300).

If the user wants to fully recline for therapeutic soaks: step up to the Drive Medical Sonaris ($450).

If you’re comparing bath lift to walk-in tub: the bath lift wins on cost and portability; the walk-in tub wins on permanence and aesthetics. See best walk-in tubs for the comparison.

The 30-second summary:
  • Default pick: Drive Medical Bellavita, $300.
  • Step up to Sonaris ($450) for full backrest recline.
  • Skip lifts under $200, battery and motor unreliable.
  • Replace battery at first cycle-degradation, not after failure.
