🛁 Does HDB Allow Bathtub Removal or Replacement Without a Permit?

A. Why This Confuses Homeowners

Many homeowners assume:

👉 “Small bathroom work = no need permit”

But in Singapore, especially under Housing & Development Board guidelines, wet area works are strictly controlled.

What Actually Determines If Permit Is Needed?

It depends on what kind of work you are doing:

✅ No Permit (Possible if ALL conditions met)

No hacking of tiles
No change to plumbing points
No impact to waterproofing

❌ Permit Required

Hacking tiles or walls
Changing drainage or pipes
Waterproofing works
Structural modifications

Root Cause of Confusion

Different contractors give different advice
Homeowners don’t realise hidden work (like hacking) triggers permit requirement

👉 It’s not about the bathtub itself
👉 It’s about what work is needed to remove or replace it

B. Why People Get Into Trouble

Trying to skip permit to “save time”?

Here’s what usually happens.

Common DIY / Shortcut Mistakes:

❌ Hacking tiles without approval
❌ Removing cemented bathtub improperly
❌ Altering drainage slope
❌ Ignoring waterproofing layer

Why This Fails in HDB Flats

Bathrooms are shared structural zones
Poor work leads to:
- Water leakage to neighbour below
- Complaints to HDB
- Forced rectification

👉 Result: You pay more than doing it properly from the start

C. Real Homeowner Experiences

🗣️ “Thought no need permit… got complaint”

“Neighbour downstairs reported leakage. HDB came down to inspect.”

🗣️ “Contractor said can skip… ended up paying more”

“Had to redo waterproofing after inspection.”

🗣️ “Simple job became big issue”

“Just wanted remove bathtub, but tiles cracked and needed hacking.”

Before vs After Scenario

No Permit / Shortcut Route:

Fast start
Hidden damage
Risk of penalty and rework

Proper Approved Work:

Controlled process
Compliance with HDB rules
Peace of mind

Assess scope of work
