Signage and Communication

Signage and communication play a vital role in toilet design. Educational posters and stickers can promote good toilet habits and hygiene practices.

Maintenance and Cleanliness

Toilets must be maintained and cleaned regularly to ensure they are in good working order. A cleaning schedule should be implemented to ensure the toilet is always clean and in good condition.

User Experience and Satisfaction

The user experience and satisfaction are critical in toilet design. User feedback should be encouraged to improve the design and functionality of the toilet.

Public Health and Hygiene

Toilets can have a significant impact on public health and hygiene. Liquid soap and hand dryers or paper towels should be provided to promote good hygiene practices.

Special Considerations

Toilets should cater to users of all ages and abilities. Family-friendly features, elderly and disabled access, and storage solutions for basic toilet amenities should be incorporated into the design.

Storage and Amenities

Storage solutions for toilet amenities such as toilet paper, soap, and cleaning supplies should be incorporated into the design. Ledges can also be added to provide additional storage space.

Lighting and Ventilation

Lighting and ventilation are essential considerations in toilet design. Adequate lighting and ventilation can improve user experience and promote good hygiene practices.

Promoting Good Practices

Toilets can be used to promote good practices such as hand washing and proper disposal of sanitary products. Educational posters and stickers can be used to encourage good practices.

Feedback and Improvement

User feedback should be encouraged to improve the design and functionality of the toilet. Improvement processes should be implemented to address issues and concerns raised by users.

Case Studies and Examples

Several toilets in Singapore have been designed to cater to specific user needs. Examples include toilets in shopping centres, hotels, hawker centres, parks, food courts, coffee shops, and tourist attractions.

When it comes to toilet design guidelines, it’s important to consider the location and its specific needs. Here are some case studies and guidelines for different locations:

Commercial and Public Spaces

Shopping centres, hawker centres, and food courts are high-traffic areas that require public toilets that are well-designed and easy to maintain. The Restroom Association of Singapore (RAS) has published a guide to better public toilet design and maintenance that provides information about good toilet design that facilitates proper use and maintenance [[1]].

One of the key factors to consider in commercial and public spaces is ventilation. Proper ventilation can help control odours and prevent the spread of germs and bacteria. The National Environment Agency (NEA) recommends that public toilets be well-ventilated and have exhaust fans installed [[1]].

Residential Toilet Design

When it comes to designing toilets in residential spaces, it’s important to consider the needs of the residents. In HDB flats, for example, toilet designs must be approved by the HDB before construction can begin. The design must meet certain requirements, such as having a minimum floor area of 1.2 square metres [[1]].

Toilet paper is another important consideration in residential toilet design. The NEA recommends that toilet paper be provided in all public toilets, and that it should be of good quality and easily accessible [[1]].

Specialised Facilities

Specialised facilities, such as parks, tourist attractions, and petrol stations, have unique needs when it comes to toilet design. For example, toilets in parks should be designed to blend in with the natural surroundings, while toilets in tourist attractions should be designed to be visually appealing and easy to find.

The Community Outreach Programme on Excreta Management (COPEH) has published guidelines for toilet designs in rural and peri-urban areas. These guidelines focus on low-cost, sustainable toilet designs that are appropriate for communities with limited resources [[1]].

Global Innovations and Trends

World Toilet Day, celebrated annually on November 19th, is an opportunity to raise awareness about the importance of proper sanitation and toilet design. In recent years, there has been a growing trend towards eco-friendly toilet designs, such as composting toilets and waterless urinals.

The Happy Toilet Programme, launched by the NEA in 2003, aims to improve toilet cleanliness and design in Singapore [[1]]. The Restroom Association of Singapore (RAS) also provides feedback and recommendations on toilet designs in Singapore [[1]].

By considering the specific needs of different locations and using innovative designs and trends, we can create better and more sustainable toilet designs that benefit public health and the environment.
