Do You Need an HDB Permit for Toilet Renovation? (2026 Rules)

Planning to hack your HDB toilet tiles? Learn about the HDB 3-year restriction rule, permit requirements, and waterproofing guidelines for toilet renovations.

The HDB 3-Year Restriction Rule

For newly built BTO flats, you are not allowed to hack the toilet floor and wall tiles for the first 3 years. This is because the waterproofing membrane needs time to settle.

When is a Permit Required?

Any hacking of tiles, replacement of toilet bowls (if moving the piping), or altering the layout requires an HDB permit submitted by a BCA approved contractor.

Cost of Toilet Renovation

Overlaying tiles costs around $3,000 to $5,000. Full hacking and waterproofing (for older resale flats) costs between $6,000 to $9,000.
