Short answer

Designers should move beyond standard bathroom layouts and actively integrate safety, accessibility, and comfort features specifically tailored to the needs of elderly users, informed by direct user input.

Field: Human Factors
Source: Pertanika journal of science & technology (2023)
Method: Qualitative research using Focus Group Discussions (FGD) and quantitative analysis using Quality Function Deployment (QFD).
Sample: 19 participants
Evidence: Strong effect

Designing bathrooms and toilets for the elderly requires a strong focus on safety, comfort, and ease of access, as these are the primary concerns identified by users and stakeholders. This human factors research insight is drawn from a 2023 study published in Pertanika journal of science & technology. Using Qualitative research using focus group discussions (fgd) and quantitative analysis using quality function deployment (qfd). with 19 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers should move beyond standard bathroom layouts and actively integrate safety, accessibility, and comfort features specifically tailored to the needs of elderly users, informed by direct user input.

Elderly Bathroom Design Prioritizes Safety and Accessibility

Designing bathrooms and toilets for the elderly requires a strong focus on safety, comfort, and ease of access, as these are the primary concerns identified by users and stakeholders.

Pertanika journal of science & technology · 2023

Key Findings

01Top customer requirements: comfort, safety, affordability, ease of entry, and anti-slippery floors.
02Top technical requirements: referencing existing accessible toilet designs, incorporating anti-slip ramps and small drains, strategic relocation of accessories, and cost categorization.
03Key issues identified by users: quality, design, cost, and function.

Application

Design takeaway

How to apply

When designing any space intended for elderly use, conduct thorough user research to identify specific safety and comfort needs, and use frameworks like QFD to translate these needs into actionable design specifications.

Project actions

01When researching user needs, consider using a mix of methods like interviews and observations.
02Use a structured approach like QFD to ensure all user requirements are considered and prioritized in your design.

Method & Evidence

AimWhat are the key design requirements for elderly-friendly bathrooms and toilets in Malaysia, considering user needs and existing challenges?

MethodQualitative research using Focus Group Discussions (FGD) and quantitative analysis using Quality Function Deployment (QFD).

ProcedureFocus groups were conducted with elderly individuals, caregivers, housing professionals, and researchers to identify issues. The gathered data was then systematically organized and analyzed within a House of Quality (HoQ) framework to prioritize customer and technical requirements for new bathroom and toilet designs.

Sample19 participants

ContextResidential bathrooms and toilets for the elderly in Malaysia.

Variables

IV["User demographics (age, caregiver status)","Existing bathroom/toilet issues (quality, design, cost, function)"]

DV["Prioritized customer requirements (comfort, safety, affordability, ease of entry, anti-slip floor)","Prioritized technical requirements (existing OKU toilet design, ramps, drains, accessory placement, cost categorization)"]

CV["Geographic location (Malaysia)","Type of dwelling (implied residential)"]

Strengths & Limitations

Strengths

+Combines qualitative user insights with quantitative prioritization methods (QFD).
+Involves a diverse range of stakeholders, including end-users, caregivers, and experts.

Limitations

The findings are specific to the Malaysian context and may not be universally applicable. The number of participants was limited.

Reliability & validity

Reliability could be enhanced by using more standardized interview protocols for FGDs. Validity is supported by the triangulation of FGD data with QFD analysis and the inclusion of multiple stakeholder groups.

Think critically

How might cultural differences influence the specific design requirements for elderly bathrooms beyond the general principles of safety and accessibility?

Design Principles

"Design for safety and accessibility by prioritizing user-centric requirements, especially in environments prone to accidents."

This research highlights critical user needs in a high-risk environment. By understanding the specific requirements for elderly users, designers can create more inclusive and secure spaces, reducing the likelihood of accidents and improving quality of life.

What This Means for Your Design

When designing bathrooms for older people, make sure they are super safe, easy to get into, and comfortable to use. Things like non-slip floors and easy-to-reach handles are really important.

Paragraph starter

Research by Hussain et al. (2023) highlights that elderly users prioritize comfort, safety, and ease of access in bathroom design, with specific technical requirements including non-slip surfaces and accessible layouts. This underscores the importance of user-centric design principles when developing solutions for this demographic.
