3 Room HDB Renovation Cost in Singapore: What You Should Expect in 2026
Buying a home is exciting. Renovating it is where reality usually kicks in.
Many Singapore homeowners start with a rough 3 room HDB renovation cost in mind, only to discover that the final bill can be much higher than expected. A simple kitchen upgrade turns into plumbing work. New flooring leads to electrical rewiring. Before long, the numbers look very different.
If you’re planning a renovation and wondering about the real 3 room HDB renovation cost, you’re not alone. It remains one of the most searched renovation topics among first-time homeowners and resale flat buyers in Singapore.
This guide breaks down realistic 3 room HDB renovation cost for 2026, explains where your money goes, highlights hidden expenses, and shows practical ways to stretch your budget without sacrificing quality.
Understanding 3 Room HDB Renovation Cost in 2026
The actual 3 room HDB renovation cost depends on several factors. The biggest one is whether you’re renovating a BTO flat or a resale unit.
A newer BTO usually requires cosmetic work, storage solutions, lighting, and furniture installation. A resale flat often needs more extensive upgrades.
Typical renovation budgets in 2026:
| Renovation Type | Estimated Cost |
|---|---|
| Basic BTO Renovation | S$20,000 – S$35,000 |
| Mid-Range BTO Renovation | S$35,000 – S$50,000 |
| Premium BTO Renovation | S$50,000 – S$70,000+ |
| Basic Resale HDB Renovation | S$30,000 – S$45,000 |
| Mid-Range Resale HDB Renovation | S$45,000 – S$65,000 |
| Premium Resale HDB Renovation | S$65,000 – S$100,000+ |
The reason resale HDB renovation costs more is simple. Older flats often require hacking works, electrical rewiring, plumbing works, waterproofing, and repairs before aesthetic upgrades even begin.
That’s why two homeowners with similar-looking homes can receive 3 room HDB renovation cost quotations that differ by more than S$20,000.
BTO vs Resale: The Biggest Cost Difference
Think of it like buying a new car versus restoring a used one.
A BTO already comes with a relatively clean foundation. A resale unit may hide ageing pipes, damaged flooring, outdated wiring, or structural issues.
Common resale expenses include:
- Hacking old tiles
- Replacing plumbing systems
- Electrical rewiring
- Ceiling repairs
- Waterproofing bathrooms
- Door replacements
These costs add up quickly and often catch homeowners by surprise.
Room-by-Room Cost Breakdown
One of the easiest ways to manage your 3 room HDB renovation cost is to understand where the money goes.
Kitchen Renovation Cost
The kitchen is usually the most expensive area in a 3-room flat.
Average kitchen renovation cost:
| Item | Estimated Cost |
| Lower Cabinets | S$3,000 – S$6,000 |
| Upper Cabinets | S$1,500 – S$4,000 |
| Countertop | S$1,500 – S$4,000 |
| Kitchen Backsplash | S$500 – S$1,500 |
| Sink & Tap | S$300 – S$1,500 |
| Appliances Installation | S$500 – S$2,000 |
Many homeowners spend heavily on built in carpentry here because storage is always a challenge in smaller flats.
If budget is a concern, focus on durable countertops and functional layouts instead of premium finishes.
Bathroom Renovation Cost
Bathrooms often involve more than just replacing fixtures.
Average bathroom renovation cost:
| Item | Estimated Cost |
| Hacking Tiles | S$800 – S$2,500 |
| Retiling | S$2,000 – S$5,000 |
| Vanity Cabinet | S$800 – S$3,000 |
| Toilet Bowl | S$300 – S$1,500 |
| Shower System | S$200 – S$1,500 |
| Waterproofing | S$500 – S$2,000 |
A full bathroom renovation cost can easily reach S$8,000 to S$15,000 for both bathrooms in a resale flat.
Living Room Renovation
The living room often sets the visual tone of the home.
Typical expenses include:
- TV feature wall
- Built in storage
- Vinyl flooring
- Lighting fixtures
- False ceiling
Budget range:
S$5,000 to S$15,000 depending on design complexity.
Bedrooms
Bedrooms are usually more affordable unless custom wardrobe systems are involved.
Common expenses:
- Custom wardrobe
- Flooring
- Feature wall
- Lighting
- Study desk
Budget range:
S$2,000 to S$8,000 per room.
The Cost of Built In Carpentry
Ask any renovation contractor where most budgets go and you’ll often hear the same answer: carpentry.
Built in carpentry remains one of the biggest renovation expenses in Singapore.
Examples include:
| Carpentry Item | Estimated Cost |
| Kitchen Cabinets | S$4,000 – S$10,000 |
| TV Console | S$1,500 – S$5,000 |
| Wardrobe | S$2,000 – S$6,000 |
| Shoe Cabinet | S$800 – S$2,500 |
| Storage Cabinets | S$1,000 – S$5,000 |
Many homeowners underestimate how quickly custom work increases costs.
A practical alternative is combining essential carpentry with ready-made furniture.
This often saves thousands while maintaining a clean and modern appearance.
Hidden Renovation Costs Most Homeowners Forget
This is where budgets often fall apart.
Many renovation quotations don’t fully prepare homeowners for unexpected expenses.
Common hidden costs include:
Electrical Rewiring
Older flats frequently need upgraded wiring.
Typical cost:
S$2,000 – S$8,000
Plumbing Works
Moving sinks, toilets, or washing machines increases plumbing expenses.
Typical cost:
S$500 – S$5,000
Permit Fees
Certain renovations require approvals and permits.
Typical cost:
S$100 – S$1,000
Disposal Charges
Removing old materials isn’t free.
Typical cost:
S$300 – S$2,000
Air Conditioning Installation
New systems often cost:
S$3,000 – S$8,000
A good rule is to keep a contingency fund equal to 10–15% of your renovation budget.
That single decision can prevent major financial stress later.
How to Compare Renovation Quotations Properly
Many homeowners compare renovation quotations based only on total price.
That’s a mistake.
The cheapest quote isn’t always the best value.
Instead, compare:
- Material specifications
- Warranty coverage
- Carpentry quality
- Scope of work
- Timeline commitments
- After-sales support
For example, one renovation quotation may include premium plywood and soft-closing hinges while another uses lower-grade materials.
The final appearance might look similar at first, but durability can differ significantly.
Always request detailed itemized quotations before signing any contract.
Renovation Loan vs Paying Cash
Not everyone wants to use savings for a large renovation project.
A renovation loan can help spread payments over time.
Advantages:
- Preserves emergency funds
- Better cash flow management
- Allows larger renovation scope
Disadvantages:
- Interest payments
- Monthly financial commitments
If you’re considering a renovation loan, calculate the total repayment amount instead of focusing only on monthly instalments.
Sometimes scaling back a few design features can save more than the interest you’d pay over several years.
Smart Ways to Reduce Renovation Costs
You don’t need a huge budget to create a comfortable and attractive home.
Here are practical ways homeowners save money.
Prioritize Function First
Focus on:
- Storage
- Lighting
- Layout
- Durability
These affect daily living more than decorative features.
Limit Hacking Works
Hacking works are expensive.
Keeping existing layouts often saves thousands.
Choose Vinyl Flooring
Vinyl flooring is popular because it’s:
- Affordable
- Durable
- Easy to maintain
- Comfortable underfoot
Mix Custom and Ready-Made Furniture
Not everything needs built in carpentry.
Combining both options creates a balanced budget.
Get Multiple Quotes
Aim for at least three renovation quotations.
This helps identify unusually high or suspiciously low pricing.
