Renovating your HDB toilets isn’t just about looks — it’s about function, safety, and long-term durability. Most homeowners choose to renovate both toilets together (master and common) to save time, cost, and hassle.
Whether it’s a new BTO handover or an ageing resale unit, toilet renovation typically includes:
• Tiling & waterproofing
• New sanitary fittings (toilet bowl, basin, taps)
• Shower accessories
• Piping & plumbing works
• Optional upgrades like vanity cabinets, rain showers, and storage niches
At Renomoji, we connect you to ID firms experienced in HDB-compliant toilet renovations — so everything gets done safely, neatly, and within HDB guidelines.
Here’s the average cost range to renovate both toilets in an HDB flat:
Flat Type | 2-Toilet Reno Cost |
|---|---|
BTO Flats | $6,000 – $8,000 |
Resale Flats (Full Overhaul) | $8,000 – $12,000+ |
Optional add-ons:
Toilet works involve wet works, so planning and coordination are key.
Here’s what to expect:
For BTO Units |
|---|
Can only start 3 years after key collection due to HDB waterproofing warranty |
You may still upgrade fittings (e.g. new vanity or shower set) without hacking |
For Resale Units |
|---|
Renovation can begin right after key collection |
Ideal to do before move-in as toilets will be unusable during works |
HDB permit needed for waterproofing and tile hacking (ID will apply for this) |
Tip: After waterproofing, HDB requires a 3-day curing and flood test before laying tiles.
Quick, no-obligation, and matched only with IDs who know their way around HDB toilets.
Here’s a full breakdown of works typically included in both toilets:
Many homeowners don’t know this — but you can install a bathtub in an HDB flat.
We’ve helped homeowners integrate bathtubs into their resale and even selected BTO units, especially in master toilets with slightly wider layouts.
✅ Standard Bathtub Size
Most HDB-friendly bathtubs are 1.2m to 1.5m in length, with compact depths of 350–450mm to fit smaller bathrooms.
✅ Best Bathtub Types for HDB Flats
✅ Waterproofing & Drainage Considerations
You’ll need proper waterproofing, a custom platform or curb, and drainage aligned with existing pipe outlets. All of this will be handled by your ID.
✅ Safety Tips
Add grab bars and anti-slip tile surfaces around the tub. Consider a lower tub height for elderly or children-friendly homes.
✅ HDB Guidelines
Bathtubs are allowed as long as weight, drainage and waterproofing comply with HDB renovation rules. Your ID will submit the permit for approval.
All projects include anti-slip tiles, waterproofing, custom vanities, and shower sets built for daily use and style.

BTOs have new waterproofing and tiles, so you can’t hack for the first 3 years. Resale flats usually require full overhaul with hacking and waterproofing.
