Bathroom safety for elderly people comes down to a few tasks the studies single out: getting into and out of the tub or shower, standing up from the toilet, and bathing when balance or strength is limited. The studies in this guide describe where those tasks go wrong and how many people who need equipment for them do not have it. The studies in this guide do not evaluate a complete bathroom layout, and this guide does not invent one. Where a point is the authors’ own explanation, it is labelled that way.
Quick answer
- In an earlier national analysis of bathroom injuries treated in US emergency departments, cited by Stevens et al. (2014), injuries were most frequent when people were in or getting out of the tub or shower.
- In a toilet-standing study of eight older women, a raised seat reduced the difficulty of standing up by 9 percent, but it also increased sway (Noroozi et al., 2025).
- Among older US adults who needed bathing or toileting equipment, 42 percent lacked it (Lam et al., 2021).
- The studies do not show which bathroom layout is safest for a given person. Talk to a doctor or occupational therapist about individual needs.
The tub and shower
Stevens and colleagues analysed falls reported by high-risk adults in one county, and they found that a fall in the bathroom was more likely to cause injury than a fall in the living room. The paper also summarises an earlier analysis of nonfatal bathroom injuries treated in US emergency departments. That analysis, which is cited rather than checked for this guide, found that “injuries occurred most frequently when people were in or getting out of the tub or shower.”
The authors list three kinds of response. The first is help: “getting assistance from another person for bathing.” The second is method: “adopting safer methods when carrying out activities in the bathroom,” with examples such as “wearing shoes with non-slip soles” and “storing toiletries on easy-to-reach shelves.” The third is equipment: “non-skid tub or shower mats, grab bars both inside and outside the tub or shower and around the toilet, and raised toilet seats.” The paper does not evaluate any of these, so they are the authors’ recommendations and not measured results. The grab bar question is covered in a separate guide on this site.
Standing up from the toilet
Noroozi and colleagues compared standing up from a toilet in eight older women, aged 72 on average, and eight younger women, aged 21 on average. The standard toilet seat was 37 cm from the floor. The raised seat was 44 cm, which is 7 cm higher. Each woman stood from each setup four times, in random order, while pressure insoles and muscle sensors recorded the movement.
The raised seat made the task easier. The paper reports that raising the seat “reduced the difficulty of standing up by 9% in both age groups.” It also reduced muscle activity in the lower legs of the older women. But the same change had a cost for stability. The conclusion is that “raising the toilet seat height, with or without bars, reduces postural stability by increasing the COP of older females when rising from a toilet.” COP here means centre of pressure, the measure of how much the body sways over the feet.
The study therefore points to a trade-off in toilet height rather than a clear answer. A higher seat makes the rise shorter and less demanding on the legs, but it also produced more sway in the women tested. The authors’ summary is that a normal height with support was the most suitable setup for these older women, but that finding is about the combination with bars, which the grab bar guide covers.
Layout and task risks at a glance
The table below lists the bathroom tasks the sources describe. Each row states only what the cited paper reports.
| Bathroom task | What the sources report | Source |
|---|---|---|
| Getting in and out of the tub or shower | Injuries most often occurred in or getting out of the tub or shower in an earlier analysis of emergency department cases. | Stevens et al., 2014 |
| Standing up from the toilet | A seat at 37 cm and one at 44 cm gave different difficulty and sway in eight older women. | Noroozi et al., 2025 |
| Bathing with a lot of difficulty | The equipment study counted “showering or bathing with a lot of difficulty” as a sign of need for bathing equipment. | Lam et al., 2021 |
| Walking indoors and holding walls | Use of a walker, or holding walls most times when walking indoors, was part of the bathing-equipment need criteria. | Lam et al., 2021 |
| Hard floors and metal fixtures | The authors suggest injuries are more likely on porcelain, metal and hard floors, but did not measure them. | Stevens et al., 2014 (explanation only) |
Who needs equipment and who has it
Lam and colleagues used a national cohort of older adults from the National Health and Aging Trends Study. They counted people who needed bathing or toileting equipment and did not have it. The study estimated that 12 million community-dwelling Medicare beneficiaries would benefit from equipment, and that an estimated 5 million, or 42 percent, had an unmet need. Among 10.6 million people who needed bathing equipment, 26 percent had none. Among 7.4 million who needed toileting equipment, 44 percent had none. Partial sets were common: 33 percent of people who needed bathing equipment had either a grab bar or a shower seat, and 40 percent had both.
The criteria were strict on purpose. The authors say that “Our criteria were thus designed conservatively, favoring specificity for needing equipment over sensitivity.” They also note that the study “did not exclude bedridden individuals requiring caregivers, because equipment may make caregiving easier.” For a bathroom plan, the relevant point is that the study ties need to capability, not to age alone. The authors write that “shower grab bars to prevent slipping and falling on a wet floor are mostly unnecessary for older persons with robust balance but are increasingly necessary for those with difficulties balancing.”
After four years of follow-up, 35 percent of people with bathing equipment needs and 52 percent of those with toileting needs had never received equipment, and some had died. The paper says this is a gap in care, and it recommends that clinicians ask about the home. The authors write: “Clinicians who notice increasing impairments or falls in their older patients should inquire about the setup of the home environment.”
Who has made bathroom changes
The Medicare study (Ng et al., 2021) reports that 55.5 percent of beneficiaries with at least one fall had some bathroom modification. Those who were more afraid of falling had higher odds of having one, and so did people with more daily-activity limits. Black and Hispanic beneficiaries had lower odds than White beneficiaries. The paper states that “The fear of falling and ADL limitations had incremental impacts on whether an older adult would have a bathroom modification.” The study does not say whether these changes are the right ones for a given bathroom.
What the sources do not say
- No best layout. None of the four sources compares bathroom layouts, such as tub versus walk-in shower, door width, or the position of a toilet relative to a shower. The sources do not give dimensions for a safe layout.
- No trial of non-slip mats or shower seats for falls. The authors recommend these, but none of the four sources measured a fall before and after one was installed.
- Small toilet study. The Noroozi study had eight older women and eight younger women. It recruited mobile older adults, and the authors write that “Data was obtained in mobile older adults, and results might differ for older adults with poor mobility.”
- Narrow population. The Stevens sample was 97.2 percent white and came from one county, and the paper states that its results “cannot be generalized to all community-dwelling older adults.”
- Unknown timing and types. The Medicare survey does not say what kind of bathroom modification each person had, or whether it was installed before or after a fall.
- No downstream outcomes. Lam and colleagues measured who had equipment, not whether having it changed injuries or independence later.
Handheld shower heads are a bathing aid that many readers ask about, and none of the four sources studied them. For that product question, see the handheld shower head guide for seniors. It answers a different question from this one.
What we could not verify
The Stevens paper’s emergency department analysis, the Noroozi citation for the share of falls on the toilet, and the earlier trials cited for home modifications were not opened for this guide. Current Medicare rules and current product specifications were not checked. The figures above are the papers’ own statements as of their publication dates, and the guide does not update them.
How we chose
Four papers were checked on 2026-10-28. Stevens et al. (2014) and Ng et al. (2021) cover falls and bathroom modifications among older adults, Noroozi et al. (2025) covers standing from a toilet, and Lam et al. (2021) covers unmet need for bathing and toileting equipment. Each was selected because it reports on a bathroom task or on the equipment that goes with it. No retail listing, price, rating or product page was used. Numbers are given as each paper reports them. Calculations are labelled where they appear. Where two papers touch the same point, each is reported separately rather than merged into one claim, and the Medicare survey is treated as showing association only.
Talk to a doctor or occupational therapist
These studies describe groups of people, and none gives advice for one person. If an older adult has fallen, struggles to get in or out of the shower, or has trouble standing up from the toilet, talk to a doctor. 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.” An occupational therapist can assess the specific tasks in the specific bathroom.
FAQ
Is a raised toilet seat safer? The toilet study found that a raised seat reduced the difficulty of standing up by 9 percent in both age groups, but it also increased sway in the older women tested. The study does not say the raised seat is safer overall.
How common is missing bathroom equipment? Among older adults who needed bathing or toileting equipment, 42 percent lacked it, according to Lam and colleagues.
Do non-slip mats prevent falls? None of the four sources measured that. Stevens and colleagues recommend non-skid mats as one step, but the paper does not test them.
Why do fear of falling and daily-activity limits matter here? The Medicare study found that both were associated with having a bathroom modification. It does not show whether those modifications were the right ones for the person.
Which bathroom layout is safest? None of the four sources compares layouts, so the guide cannot name one.
