Maintaining clear communication with your neighbours during the renovation process is important. For example, inform your neighbours about the renovation schedule to minimise inconvenience. Additionally, stay in touch with HDB officials to address concerns, seek guidance, and ensure a smooth and compliant renovation process.

The Don'ts of HDB Toilet Renovation

1. Don't Proceed with Renovation Without Obtaining Proper Approvals

Only proceed with your renovations after obtaining the necessary approvals because failing to acquire the required permits can lead to inconvenience, such as the need to reverse the renovation work. So it is important to ensure and obtain all the proper documentation and permissions before starting any renovation activities.


2. Don't Make Structural Modifications without Professional Advice

HDB Toilet Renovation Guidelines

Structural modifications in an HDB toilet should only be undertaken with professional advice. HDB flats have specific structural requirements, and any alterations to load-bearing walls, beams, or columns can compromise the integrity of the entire building. So always engage a qualified professional, such as a structural engineer or HDB-registered contractor, to assess the feasibility of structural modifications and provide expert guidance.


3. Don't Overlook the Importance of Waterproofing to Prevent Leaks

HDB Toilet Renovation Guidelines

Ensure proper waterproofing materials and techniques are employed during the renovation to prevent moisture penetration and subsequent issues. Remember that waterproofing should be noticed, and neglecting its measures can result in water leaks that can damage your unit and your neighbouring units.


4. Don't Neglect the Responsible Disposal of Construction Debris

HDB Toilet Renovation Guidelines

Follow guidelines for waste management, such as using designated disposal areas and keeping the renovation site clean and organised to demonstrate respect for the community and contribute to a smoother renovation process.


5. Don't Compromise on Electrical Safety or Attempt Unauthorised Modifications

Electrical safety should never be compromised, and continuously engage a qualified electrician to handle any electrical work, such as installing lighting fixtures, power outlets, or switches, to avoid electrical hazards and fire risks.


HDB Restrictions and Requirements

HDB Toilet Renovation Guidelines

In addition to these general guidelines, it's important to be aware of specific restrictions and requirements outlined by HDB for certain aspects of HDB toilet renovation. 

Here are some additional considerations:

1. Construction of Cement Mortar Kerb

When constructing a kerb within the bathroom or toilet area, it should not exceed 100mm in height and 100mm in width to ensure that the kerb remains within the designated limits and does not impede the overall functionality of the space.

2. Enlargement of Bathroom/Toilet

If you plan to enlarge your bathroom or toilet beyond its original dimensions, you can do so after the first 3 years of the block's completion, but there are certain restrictions to keep in mind. The maximum width and area of the extension should not exceed 600mm and 0.6m², respectively. Additionally, the extended area can only be used as a "dry area," typically for installing items like a wash basin or shelves. It's important to ensure that the existing gas riser and branch pipe are not enclosed within the extended bathroom or toilet area.

3. Replacement of Bathroom/Toilet Vent

You can replace the vent in your bathroom or toilet, but there are specific requirements for the glass louvres used in the vent. The glass louvres must be at least 6mm thick and of the wire-glass type, and every glass, louvre must have an aluminium U-channel cleat safety device to ensure secure installation and prevent accidents.
