The National Construction Code (NCC) 2019 introduced significant changes, including new provisions for bathroom falls. These updates aim to enhance safety and accessibility, making bathrooms more user-friendly for everyone. This article delves into the NCC 2019 bathroom falls, explaining their purpose, the changes they bring, and their impact on construction and design.
Bathroom falls, also known as shower recesses or shower bases, are the lowest point in a bathroom where water drains. They are a critical aspect of bathroom design, as they ensure water is directed away from the living space, preventing slips, trips, and falls, and minimizing water damage.
The NCC 2019 places a stronger emphasis on bathroom falls due to the increasing recognition of the role they play in accessibility and safety. With an aging population and a growing need for inclusive design, the NCC 2019 seeks to ensure that bathrooms are safe and accessible for all users, including those with disabilities, the elderly, and young children.
The new provisions in NCC 2019 require that bathroom falls are no higher than 30mm (1.2 inches) above the finished floor level. This change aims to make it easier for wheelchair users and those with mobility issues to access showers and baths safely.
Lower bathroom falls also reduce the risk of trips and falls for all users. By minimizing the difference in level between the bathroom floor and the shower recess, the NCC 2019 helps to create a safer bathroom environment.
To understand the impact of the NCC 2019 changes, let's compare the old and new provisions for bathroom falls.

| Provision | NCC 2019 | NCC 2016 |
|---|---|---|
| Maximum height of bathroom fall | 30mm (1.2 inches) | Up to 150mm (5.9 inches) |
| Requirement for slip-resistant surfaces | Mandatory in all showers and baths | Not explicitly stated |
The NCC 2019 changes have significant implications for the construction and design industries. Here are some key considerations:
Building surveyors and inspectors will be responsible for ensuring that bathroom falls comply with the NCC 2019. Non-compliance can result in fines and delays in the approval process, making it crucial for all stakeholders to understand and adhere to the new provisions.
The NCC 2019 bathroom falls provisions are a step towards more inclusive and safer bathroom design. As our understanding of accessibility and safety continues to evolve, we can expect to see further innovations in bathroom design and construction. By embracing these changes, we can create bathrooms that are not only functional and safe but also beautiful and enjoyable spaces.
