Bath lifts: how they work, weight limits, and bath lift vs walk-in tub

Quick answer

A bath lift is a seat that sits in your own bathtub. You sit on it at the height of the tub’s edge and swing your legs over. Then the lift, powered by a rechargeable battery, lowers you into the water and raises you back up when you’re done [8] [10]. The makers of the lifts in this guide list weight limits from 300 lb to 400 lb [9] [8] [11]. Unlike a walk-in tub, a bath lift needs no plumbing or electrical work, and it can be taken out of the tub [9] [8].

Check that it suits the person first

A bath lift does the lowering and lifting. But the person still has to sit down on the seat at the edge of the tub, then turn and lift each leg over the side [8]. SuperHandy says users of its cushion need enough upper body strength to support themselves [12]. The instructions for the Bathmaster Sonaris2 say a health care professional or caregiver should judge whether a lift suits the person. They list things to consider, such as the person’s size and weight, upper body strength, balance, coordination, thinking and memory, and hip flexibility [8]. An occupational therapist can assess this, and can compare a bath lift with other options, like a tub transfer bench.

Bath lift or walk-in tub?

	Bath lift	Walk-in tub
How you get in	Sit on the seat’s side flap at the edge of the tub, slide back, swing your legs over, then lower the seat [8]	On American Standard’s 32 x 52 in model, for example, you step through a door with a low threshold and sit on a built-in seat at chair height [13]

Where to buy bath lifts

Home health stores sell bath lifts, and so do some online stores. In Alberta, the province’s program provides equipment through approved vendors, so check Costs and funding before you buy [6].

The table lists bath lifts whose makers publish their weight limits and sizes. It’s sorted by the maker’s weight limit, lowest first. The figures come from the makers’ pages and instructions, linked in the sources. We haven’t tested these products. In our search, few bath lifts sold online published full specs, so the list is short.

How a bath lift works

The lifts above work in two ways. Drive’s lift and the Sonaris2 are a seat on a powered frame, with a backrest that tilts back once the seat is down [10] [8]. SuperHandy’s is an inflatable seat and backrest cushion, raised and lowered by a battery-powered air system [11]. Its manual says to fully inflate the cushion before slowly lowering yourself into the tub [12]. All three hold to the bottom of the tub with suction cups or suction feet [10] [8] [12].

Using one, step by step, from the Sonaris2’s instructions [8]:

Raise the seat until its side flaps rest level on the edge of the bath.
Run the bath water and check the temperature.
Stand with your back to the bath and sit on the outer side flap, with the seat behind you.
Slide back until you’re in the middle of the seat.
Turn, lifting each leg over the edge of the bath.
Press the down button to lower the seat, keeping your hands and feet away from underneath it. At the bottom, release the button and press it again to recline the backrest, up to 40 degrees on this model.
To get out, raise the seat until its side flaps rest on the edge of the bath. Turn, lifting each leg back over the edge, slide out onto the side flap and stand up with your back to the bath.

On the Sonaris2 and the Bellavita Dive, the battery is in the hand control. Both makers say to charge it away from the bathroom [8] [10].

Will a bath lift fit your tub?

Bath lifts need a tub of the right shape and size. The Sonaris2’s instructions say a few extremely narrow or contoured tubs won’t take a powered bath seat, and give the tub sizes it needs. For example, the bottom of the tub must be more than 31.5 in (800 mm) long, and 11 to 24 in (280 to 610 mm) wide where the suction feet sit. The tub’s height must be under 18 in (455 mm), or 19 in (475 mm) with the maker’s height adapter, which raises the lift by up to 0.75 in (2 cm) [8]. Drive’s Bellavita Dive has a base plate 24 in (61 cm) long and about 12 in (30 to 31 cm) wide [10].

Before you buy a bath lift

From simpleaging.com. This checklist is general information, not medical advice.

The person

An occupational therapist, physiotherapist or doctor has talked about whether a bath lift suits the person [8].
The maker’s weight limit is above the person’s weight.
The person can sit on the side flap and lift each leg over the edge of the tub, or has someone to help [8].

The tub

You’ve measured the tub’s length and width along the bottom and its height, and compared them with the maker’s requirements [8].
The tub bottom is smooth. SuperHandy says not to use its cushion on refinished, rippled or textured tub surfaces, where the suction cups can’t hold [12].
Grab bars or handles on the tub won’t catch the seat’s side flaps. The Sonaris2’s instructions say side flap protectors may be needed if the tub has handles [8].

Every bath

The tub bottom is clean, and non-slip mats are out of the tub. Drive says to take them out [10], and the Sonaris2’s instructions say its suction feet must not rest on a bath mat [8].
The battery is charged. Drive says to charge it after every bath [10].
A phone or alarm is within reach if the person bathes without help [8].

Features to compare

Weight limit. Use the maker’s figure for the exact model. The lifts in the table list 300 lb to 400 lb [9] [11]. In our research, store listings didn’t always match the maker’s figure, and Drive’s product page (300 lb) and its manual (140 kg, about 309 lb) differ too [9] [10]. If two figures differ, ask the maker which applies to your model.
How low the seat goes. The lower it goes, the deeper you sit in the water. Drive’s lift and the Sonaris2 go down to 2.6 in (6.5 cm) [8] [9].
Backrest. Drive’s backrest reclines to 50 degrees, and the Sonaris2’s to 40 degrees [9] [8].
Battery. Check what happens when the charge runs low. Drive says the Bellavita Dive lowers only if the battery has enough charge to raise it again [10]. The Sonaris2’s instructions say it won’t lower when the battery is low, and will only rise [8]. SuperHandy says its cushion warns you in advance, and can still complete one to two lifts after the warning [11].
Weight of the parts. Someone has to lift it in and out of the tub. The Sonaris2’s seat unit weighs 16 lb (7.4 kg) and its backrest 8 lb (3.7 kg) [8]. Drive’s lift weighs 21.8 lb in all [9].
Materials. SuperHandy’s suction cups contain latex [12].

Costs and funding for bath lifts

Store prices change, so we don’t list them. Alberta’s program publishes the most it pays for each type of bath lift, shown below. A few programs and tax rules may help with the cost.

Canada

Ontario Assistive Devices Program

Ontario’s program doesn’t pay for bath lifts. It lists “bath and shower aids (for example, benches, chairs, bath lifts)” among the equipment it doesn’t cover [2].

Alberta Aids to Daily Living

Alberta’s program funds portable bath lifts for Albertans with a long-term disability, chronic illness or terminal illness [5] [6]. You start with an assessment by a health care provider the program approves, for example a registered nurse, occupational therapist or physiotherapist [6].

Its 2025 product list sets the most it pays for each type [5]:

C$1,595 for a bath lift without a reclining back
C$1,890 for one with a reclining back
C$2,150 for a heavy-duty lift, with a weight limit over 325 lb
C$2,425 for one with a reclining back and side supports

These prices include the battery and hand control. The basic category, with no reclining back, doesn’t cover inflatable bath cushions. The program funds one bath lift every four years. It also funds only one bathing aid for each need, so not both a bath lift and a wheeled shower commode chair. Its approved makers include Drive, Invacare and Medline. If the lift you choose costs more than the program’s maximum, you pay the difference [5]. You also pay a share: 25% of the cost of program benefits, up to C$500 per family each benefit year (July 1 to June 30). Low-income Albertans may be exempt [7].

BC Rebate for Accessible Home Adaptations

BC’s rebate schedule doesn’t list bath lifts. It says the list isn’t complete, and that adaptations not on it may be considered with an assessment from an occupational therapist, physiotherapist or medical professional [3]. Our walk-in tub guide explains how the program works.

Medical expense tax credit

The Canada Revenue Agency’s medical expense guide lists “bathroom aids to help a person get in or out of a bathtub or shower or to get on or off a toilet,” and a prescription is needed [1]. Keep the prescription and the receipt in case the CRA asks for them [1]. Our medical expense tax credit calculator estimates the federal credit from your medical costs and net income.

United States

Medicare

Original Medicare doesn’t cover bath lifts. Its equipment reference list says to deny bathtub lifts as a “convenience item; not primarily medical in nature” [4]. If you have a Medicare Advantage plan, ask whether it offers extra benefits for bathroom safety. Our guide to home safety funding in the US explains those benefits and other programs.

Questions to ask

An occupational therapist, physiotherapist or doctor

Can the person get on and off the seat at the edge of the tub safely, with or without help?
Which would suit this person and this bathroom: a bath lift, a tub transfer bench or another change?
Should someone be nearby during baths?

The store or supplier

What is the maker’s weight limit for this exact model?
Will it fit our tub? Which measurements do you need?
How heavy is each part, and how does it come apart for lifting?
What happens when the battery runs low? Can we buy a spare battery or hand control?
In Alberta: are you an approved vendor for the Aids to Daily Living program? [6]

Safety notes and when to talk to a professional

Use it only for bathing. Drive says its lift isn’t a ladder, an aid for getting in and out outside the tub, or a support [10]. The Sonaris2’s instructions say not to use it as a support to help you stand or steady yourself [8].

Keep hands and feet clear. Drive says to lean against the backrest and rest your hands in your lap while the seat moves, and not to put your hands between the edge of the tub and the lift [10]. The Sonaris2’s instructions say to keep hands and feet away from the underside of the seat [8].

Don’t bathe alone if it isn’t safe to. Drive says people with serious physical disabilities or confusion should never be left in the tub unsupervised [10]. Keep a phone or alarm within reach [8]. Our guides to medical alert systems in Canada and in the US explain the options.

Follow the low-battery signal. The Sonaris2’s instructions say not to use the lift once its low-battery light stays on, and to recharge it first [8]. SuperHandy says never to disconnect the air tube to lower yourself [12].

Test it first. Drive says to do a test run, moving the lift up and down, before using it [10]. The Sonaris2’s instructions also say to test it before the bather uses it [8].

When to talk to a professional. If someone has trouble getting in or out of the tub, has fallen, or feels unsteady, talk to a doctor. An occupational therapist can look at the person and the bathroom and help compare a bath lift, a transfer bench, grab bars and other changes. Our bathroom safety guide covers each change in one place.
