Buying an HDB flat is one of the biggest financial commitments for most Singaporeans. Whether you’ve just collected the keys to your new Build-To-Order (BTO) home or purchased a resale flat, renovation is the next major investment that transforms an empty space into a comfortable and functional home.
One of the first questions homeowners ask is:
“How much should I budget for an HDB renovation in 2026?”
The answer depends on several factors, including the size of your flat, the condition of the property, your preferred interior design style, the materials you choose, and the amount of custom carpentry required.
While every renovation project is unique, having a realistic budget before you begin can help you avoid unexpected costs and make informed decisions throughout the renovation process.
In this guide, we’ll break down the average renovation costs for different HDB flat types in Singapore, explain what influences pricing, and share practical tips to help you maximise your renovation budget without compromising on quality.
Average HDB Renovation Costs in Singapore (2026)
While every renovation project is unique, the following figures provide a realistic estimate for homeowners planning their budget.
| HDB Flat Type | Estimated Renovation Cost |
|---|
| 2-Room BTO | SGD 18,000 – 30,000 |
| 3-Room HDB | SGD 25,000 – 40,000 |
| 4-Room HDB | SGD 35,000 – 55,000 |
| 5-Room HDB | SGD 45,000 – 70,000 |
| Executive Apartment | SGD 55,000 – 90,000+ |
| Resale HDB (Major Renovation) | SGD 60,000 – 120,000+ |
These figures represent complete renovation projects that typically include carpentry, flooring, painting, electrical work, plumbing, lighting, and basic interior finishes.
Keep in mind that luxury materials, extensive hacking, premium appliances, or bespoke design features can increase the overall cost.
Why Are Resale HDB Renovations More Expensive?
Many homeowners are surprised to discover that renovating a resale flat often costs significantly more than renovating a new BTO.
This is because resale units usually require additional work before the new design can begin.
Common additional costs include:
- Hacking existing tiles and walls
- Removing old built-in furniture
- Replacing outdated electrical wiring
- Upgrading plumbing systems
- Waterproofing bathrooms
- Floor levelling
- Ceiling repairs
- Wall restoration
Depending on the condition of the unit, these preparatory works alone may account for several thousand dollars.
What Factors Affect Renovation Costs?
1. Carpentry
Custom carpentry is usually the largest expense in an HDB renovation.
Examples include:
- Kitchen cabinets
- Wardrobes
- TV feature walls
- Shoe cabinets
- Storage benches
- Study tables
- Display shelves
The more customised your storage solutions, the higher the overall cost.
However, quality carpentry also adds long-term functionality and maximises space—an important consideration for many HDB homeowners.
2. Kitchen Renovation
The kitchen is one of the busiest spaces in any home.
A typical kitchen renovation may include:
- Upper and lower cabinets
- Countertops
- Sink and tap installation
- Backsplash
- Lighting
- Appliances
- Electrical upgrades
Premium countertop materials such as quartz or sintered stone generally cost more than laminate but offer greater durability and easier maintenance.
3. Bathroom Renovation
Bathrooms often require specialist work.
Typical costs include:
- Waterproofing
- Wall and floor tiling
- Shower screen installation
- Vanity cabinet
- Basin
- Toilet bowl
- Plumbing
- Mirrors
- Accessories
Cutting corners on waterproofing can lead to costly repairs in the future, making it one area where quality should always take priority.
4. Flooring
Flooring has a major influence on both the appearance and the overall renovation budget.
Popular flooring options include:
- Vinyl flooring
- Porcelain tiles
- Homogeneous tiles
- Engineered wood
- SPC flooring
Each material offers different benefits in terms of durability, maintenance, comfort, and cost.
5. Electrical Works
Modern homes require more electrical points than ever before.
Typical electrical works include:
- Additional power sockets
- Lighting installation
- Ceiling fan wiring
- Air-conditioner points
- Data ports
- Smart switches
- USB charging outlets
Planning your electrical layout early helps avoid expensive changes during construction.
6. Interior Design Style
Your preferred design style also affects your renovation budget.
For example:
Minimalist
Simple lines, clean layouts, and fewer decorative features typically result in lower renovation costs.
Modern Contemporary
May include feature lighting, customised finishes, and premium materials.
Japandi
Often incorporates natural wood textures, bespoke carpentry, and carefully selected finishes.
Modern Luxury
Usually features marble-look surfaces, designer lighting, fluted panels, glass partitions, and custom-built furniture, making it one of the more premium renovation styles.
Where Should You Invest More?
Every homeowner has a budget, but some areas are worth spending a little more on because they affect long-term comfort and durability.
We recommend prioritising investment in:
Kitchen Cabinets
High-quality hardware and durable finishes ensure smooth daily use for many years.
Wardrobes
Well-designed wardrobes maximise storage while keeping bedrooms organised.
Waterproofing
Proper waterproofing helps prevent water leakage and expensive repairs.
Electrical Works
A safe and future-ready electrical system is essential for modern living.
Lighting
Good lighting improves both functionality and the overall atmosphere of your home.
Where Can You Save Money?
Saving money doesn’t always mean choosing the cheapest option.
Instead, focus on making smart decisions.
Some practical ways to reduce renovation costs include:
- Avoid unnecessary hacking where possible.
- Keep the original layout if it already works well.
- Finalise your design before construction begins.
- Choose practical materials instead of expensive alternatives.
- Use built-in storage only where it’s truly needed.
- Combine multiple renovation works under one contractor to improve coordination.
Careful planning often saves more money than making last-minute changes.
Should You Choose the Lowest Quotation?
It’s natural to compare renovation quotations, but the cheapest price isn’t always the best value.
When evaluating quotations, consider:
- Scope of work
- Material specifications
- Warranty coverage
- Workmanship quality
- Project management
- Timeline
- After-sales service
A transparent quotation with clear inclusions helps minimise misunderstandings and unexpected costs later in the project.
How Long Does an HDB Renovation Take?
Although every project is different, typical renovation timelines are:
| Property Type | Estimated Duration |
| BTO Flat | 6–8 weeks |
| 3-Room HDB | 8–10 weeks |
| 4-Room HDB | 8–12 weeks |
| 5-Room HDB | 10–12 weeks |
| Resale HDB | 10–16 weeks |
Projects involving major hacking, extensive custom carpentry, or complex design features may require additional time.
How to Plan Your Renovation Budget?
A practical approach is to divide your budget into key categories:
- Carpentry
- Flooring
- Kitchen
- Bathroom
- Electrical
- Painting
- Lighting
- Glass Works
- Contingency Fund
It’s also advisable to set aside around 5%–10% of your total renovation budget for unexpected expenses or upgrades during the project.
Final Thoughts
Renovating your HDB flat is more than just improving its appearance—it’s about creating a comfortable, functional home that suits your family’s lifestyle for years to come.
While renovation costs in Singapore continue to vary depending on property type, materials, and design choices, careful planning and working with an experienced renovation team can help you stay within budget without compromising quality.
Rather than focusing solely on the lowest quotation, consider the overall value, workmanship, communication, and long-term support offered by your renovation partner.
A well-planned renovation not only enhances your living experience but also adds lasting value to your home.
