When we think about ergonomics, we often picture office chairs or desks. Rarely do we apply the same thinking to the bathroom. Yet for many people living with long-term conditions, the bathroom can be one of the most challenging environments in the home. Toileting is not a single task, it is a sequence of physical, cognitive, and sensory demands. When something goes wrong, it is often not a “user problem failure”, but a problem of design.
Using a toilet independently requires a person to:
- Navigate the space, often with a mobility aid
- Transfer safely on and off the toilet
- Manage clothing using fine motor skills
- Maintain balance in a restricted environment
- Complete personal hygiene, including a “twist and reach” movement
If the environment does not support even one of these steps, independence can be lost.
In simple terms, ergonomics is about getting the right fit between people and all the stuff they engage with. The aim of a good ergonomic design should reduce the effort on the user, increase efficiency and reduce the risk of error. Fundamentally it is about ease of usability. Having a good understanding of these principles can ensure that the best solution is identified for the people we work with.

Physical ergonomics
- Toilet height directly affects safety and effort. Having the ability to set a toilet at the correct height for optimal position will support both safer transfers and more effective toileting posture.
- When someone struggles with the twisting and reaching required for cleaning, it can be frustrating and a point where independence can be lost. Wash and dry toilets remove this barrier by automating washing and drying, reducing strain and enabling continued independence.
- Consideration of peripheral equipment is also important. Does the user use a shower chair for example? Does this impact on position?
Cognitive ergonomics
Toileting also requires sequencing and decision-making. Simple to use controls such as one-touch operation reduce cognitive load and make the task easier to complete confidently. Controls should be intuitive and not confusing. Too many options can prevent a person with cognitive difficulties achieving the independence a wash and dry toilet aims for.
The sensory experience
Sensory factors are often overlooked but can determine whether equipment is used or rejected.

Consider:
- Tolerance of water and warm air during the wash and dry cycle
- Sensitivity to temperature or pressure
- Noise from the system
Adjustable settings allow water flow, temperature, and air to be graded to the individual. Where possible, trialling equipment can help ensure the person is comfortable with the experience. Many Changing Places https://www.changing-places.org/ have Closomat toilets that can be tested.
More than function: Dignity and design
For many, appearance matters. Equipment that looks overly clinical can be rejected and therefore for some people aesthetics impact on usability. Designs such as the Closomat Palma Vita are intentionally styled to look like a standard toilet, helping maintain dignity and a sense of normality within the home.
Designing for today and tomorrow
Good ergonomic design is also about future-proofing. Adjustable features and flexible layouts allow the environment to adapt as needs change, reducing the need for further intervention. This can be particularly relevant for individuals with a deteriorating or degenerative condition.
Conclusion
Toileting is a complex activity that relies on the interaction between the person, the environment, and the task. When that interaction fails, independence is at risk. By applying ergonomic principles, it becomes clear that many challenges can be addressed through better design. Solutions such as the Closomat Palma Vita demonstrate how thoughtful, user-centred design can reduce effort, support dignity, and enable independence.
Ultimately, when design works well, it becomes almost invisible, quietly supporting one of the most essential activities of daily life.
