Grab bars for seniors help with one specific task, standing up from a toilet, according to one small controlled study. A national cohort study finds that many older adults who need bathing or toileting equipment do not have grab bars or seats, and a 2025 toilet study reports the effect of bars on standing effort. None of the four sources checked for this guide measured whether grab bars prevent falls in the bathroom. The evidence supports the use of bars for a specific task, and it leaves the fall question open.
Quick answer
- In a study of eight older women, adding bilateral grab bars cut the difficulty of standing from a toilet by 31 percent, compared with 17 percent in younger women (Noroozi et al., 2025).
- Bars did not lower the difficulty further when combined with a raised seat, and the authors favour a normal-height toilet with bars for older women who can rise from it.
- Among older adults who needed bathing or toileting equipment, 42 percent lacked it, and Medicare Part B did not cover grab bars as of the 2021 paper (Lam et al., 2021).
- No source shows a reduction in falls from grab bars alone.
What the toilet study tested
Noroozi and colleagues tested four toilet setups: a normal toilet with a seat 37 cm from the floor, a raised seat at 44 cm, and the same two with horizontal grab bars on both sides. The bars were at 79 cm, with a diameter of 3.8 cm. Eight older women, aged 72 on average, and eight younger women, aged 21 on average, each stood from each setup four times. The older women were able to stand up independently from both a chair and a standard toilet. Pressure insoles recorded how the weight moved from the buttocks to the feet, and surface sensors recorded muscle activity.
The bars changed how the task was done. The paper reports that adding bars reduced the time between peak pressure at the heel and peak pressure at the front of the foot, which the authors use as the measure of difficulty, by 31 percent in older women and 17 percent in younger women. The table below gives the figures the paper states for the bars.
| Measure (as stated in the paper) | Older women | Younger women |
|---|---|---|
| Reduction in standing difficulty with grab bars | 31% | 17% |
| Reduction in standing difficulty from a raised seat | 9% | 9% |
| Change in sway speed when bars were added | Decreased by 19% | Decreased by 5% |
| Change in calf activity with bars (older women) | Lower; bars reduced biceps femoris and calf activity | |
| Change in front-thigh activity with bars at normal height (older women) | Higher by 21 percent; the authors describe this as a trade-off | |
The authors’ recommendation follows from these results: “Given the importance of safety, selecting a normal toilet height, with a bilateral grab bar, is the most suitable configuration for older females.” They add that “The combination of raising the seat and adding the grab bars failed to further reduce STS difficulty compared to the normal toilet with bars condition.” The paper’s STS abbreviation means sit-to-stand.
What the sources say about falls
The toilet study measured sway and effort, not falls. Falls come up elsewhere in the sources, but none of them isolates grab bars. Lam and colleagues write that “As part of multifactorial interventions in randomized clinical trials, home modifications reduce falls.” That sentence refers to trials of several changes at once, not to grab bars alone, and the paper does not separate the effect of a bar from the rest of the package.
The Medicare study (Ng et al., 2021) makes a similar point in its discussion. The authors write that “Certain home modifications, such as grab bars in showers, could substantially prevent falls and support independent living,” and they cite earlier trials for that claim. Those trials were not checked for this guide, so the statement is the authors’ summary, not a finding of the Medicare survey.
The Stevens study adds context on where injuries happen. Its authors note that falls in the bathroom were more likely to cause injury than falls in the living room. They conclude that these results “support the need to promote safety modifications such as grab bars and may indicate a need for assistance with bathing.” The paper recommends grab bars “both inside and outside the tub or shower and around the toilet,” but it did not study bars in those places.
Who has grab bars
Lam and colleagues counted older adults who needed bathing or toileting equipment and did not have it. The study estimated that 12 million community-dwelling Medicare beneficiaries would benefit, and that about 5 million, or 42 percent, had unmet need. Among 10.6 million who needed bathing equipment, 26 percent had neither a grab bar nor a shower seat, 33 percent had one, and 40 percent had both. Among 7.4 million who needed toileting equipment, 44 percent had neither a toilet grab bar nor a raised seat.
The authors also name stigma as one reason for the gap. Some people may find equipment stigmatizing, and “Aesthetics are unappealing,” the paper says. The authors suggest that “Equipment trials would let individuals test changes before committing to permanent modifications.” Equipment users in the same paper “report increased independence and feeling safer.”
Walkers were a clue but not a solution. The study reports that “among older adults who use a walker indoors, only 59% also had shower grab bars and a bath seat.” The authors write that equipment often came piecemeal, and that “many receiving some equipment rather than the full set of equipment most experts recommend.”
The Medicare survey asked whether a bathroom had modifications “such as grab bars or a shower seat.” Among beneficiaries with at least one fall, 55.5 percent answered yes. The paper says the survey “did not specifically ask about the modification types, such as a raised toilet seat, grab bar, or non-slip floor,” so it cannot show how many of those homes had grab bars.
Cost and coverage
Lam and colleagues state that “Medicare Part B does not cover grab bars, shower seats, or raised toilet seats as durable medical equipment,” and they describe each item as low cost. That statement reflects coverage at the time of the 2021 paper. The authors also note that Medicare Advantage beneficiaries “may have access to insurance plans with additional benefits to cover equipment,” but their data did not include Medicare Advantage enrollment. Medicare Part B does cover walkers, which the authors contrast with the bathroom items. The paper also cites cost-effectiveness analyses that estimate the benefit of equipment at six times its cost, with greater value for older adults who have fallen.
The Medicare paper is blunter about home modifications in general. It says that “Medicare has strict and very limited coverage for home modifications, if any.” It adds that a grab bar may be covered “only if it is deemed medically necessary” with a professional assessment. Coverage rules change, so check the current rules with Medicare or a plan before buying.
What the sources do not say
- No fall outcomes for grab bars. None of the four sources measured falls before and after grab bars were installed. The Medicare survey does not say whether a fall happened before or after a modification was made.
- No installation guidance. The sources do not say where a bar should go, how it should be anchored, or what load it should carry. The toilet study used bars in one position, and the authors call for future work on “measuring the forces applied to the grab bars.”
- Mobile women only in the toilet study. The authors write that “Data was obtained in mobile older adults, and results might differ for older adults with poor mobility.” The study had 16 women in total.
- One side only. The authors recorded muscle activity from the dominant side only and say that approach “overlooks the potential asymmetries in muscle activation.”
- Conservative criteria. Lam and colleagues designed their criteria to favour specificity, so the 42 percent figure may understate need. The paper says that “Our criteria were thus designed conservatively, favoring specificity for needing equipment over sensitivity.”
- No clinical outcomes. Lam and colleagues did not examine what happened to people who went without equipment, such as injury or independence.
What we could not verify
The Medicare coverage statement in the Lam paper was not checked against current Medicare rules, and the guide does not say what coverage applies today. The Gitlin (2006) and Tchalla (2012) trials that the Medicare paper cites for grab bars and falls were not opened. The cost-effectiveness analyses that Lam and colleagues cite were not opened. Load ratings, anchoring methods and installation standards for bars were not checked, because none of the four papers reports them.
How we chose
Four papers were checked on 2026-10-28. Noroozi et al. (2025) is the only study in this set that tested grab bars directly. Lam et al. (2021) and Ng et al. (2021) cover equipment and modification use across national samples, and Stevens et al. (2014) covers where falls cause injury in the home. Each source was included because it reports on grab bars, on the bathroom tasks they are meant for, or on their cost and coverage. No retail listing, price, rating or product page was used, and no product is recommended. Figures are given as each paper states them.
Talk to a doctor or occupational therapist
Whether a grab bar suits a specific person depends on balance, strength and how the bathroom is used, and none of these papers gives advice for one person. Lam and colleagues note that “Where available, partnerships with occupational therapists and experienced handypersons can help conduct in-home assessments, provide information on what to get, and help with installation.” If you are deciding for an older family member, talk to a doctor or an occupational therapist first.
FAQ
Do grab bars help older adults stand up from a toilet? In the eight-woman study, adding bilateral bars reduced the difficulty of standing by 31 percent in older women. The participants were mobile, and the study did not measure falls.
Does Medicare cover grab bars? The 2021 Lam paper states that Medicare Part B does not cover grab bars as durable medical equipment. Current coverage was not checked, so confirm the rules with Medicare or a plan before buying.
Where should grab bars go? The toilet study tested bars beside a toilet. Stevens and colleagues recommend bars inside and outside the tub or shower and around the toilet, but none of the sources gives placement or anchoring guidance.
Which grab bar should I buy? The sources do not compare products, so this guide does not name one.
