Renating an HDB flat is a major financial commitment, and for many homeowners, it is the second-largest expense after purchasing the property itself. Whether you are moving into a new Build-To-Order (BTO) flat or renovating an older resale unit, understanding renovation costs is essential for proper budgeting.
One of the first questions homeowners ask is: “How much does it cost to renovate an HDB flat in Singapore in 2026?”
While there is no fixed price, most HDB renovation projects in Singapore typically range from S$15,000 to over S$100,000, depending on the flat size, condition of the property, design requirements, materials selected, and extent of renovation work.
A simple renovation involving painting, basic flooring, and essential carpentry will cost significantly less than a complete makeover that includes hacking works, custom-built furniture, kitchen remodeling, bathroom upgrades, electrical rewiring, and premium finishes.
This guide explains the key factors affecting renovation costs, realistic budget ranges, and practical ways to manage your renovation expenses effectively.

Factors That Influence HDB Renovation Costs
Flat Size
Larger flats require more materials, labour, and time to renovate.
A 5-room HDB flat generally costs more to renovate than a 3-room flat because of:
- Greater flooring area
- Additional rooms
- More electrical points
- Larger carpentry requirements
Property Condition
The condition of the flat can significantly impact renovation costs.
New BTO flats usually require less work because the structure, flooring, plumbing, and electrical systems are relatively new.
Older resale flats often require:
- Hacking and demolition
- Tile replacement
- Plumbing upgrades
- Electrical rewiring
- Ceiling repairs
- Waterproofing work
These additional works can substantially increase renovation costs.
Design Complexity
A minimalist design generally costs less than highly customized interiors.
Features that often increase costs include:
- Curved carpentry
- Custom storage systems
- Feature walls
- Designer lighting
- Smart home systems
- Premium finishes
The more customized the design, the higher the labour and material costs.
Cost Breakdown by Renovation Area
Kitchen Renovation
The kitchen is usually one of the most expensive areas of an HDB renovation.
Typical kitchen renovation costs may include:
- Cabinets
- Countertops
- Backsplash installation
- Plumbing works
- Electrical works
- Appliance integration
Many homeowners spend between S$8,000 and S$25,000 on kitchen renovations depending on specifications.
Bathroom Renovation
Bathroom renovation costs vary depending on the scope of work.
Common expenses include:
- Tile replacement
- Waterproofing
- Shower systems
- Vanity cabinets
- Toilet bowls
- Plumbing modifications
Bathroom renovations typically range from S$4,000 to S$15,000 per bathroom.
Carpentry Works
Custom carpentry is often one of the largest renovation expenses.
Common carpentry items include:
- Kitchen cabinets
- Wardrobes
- TV consoles
- Shoe cabinets
- Study desks
- Storage systems
Extensive carpentry can account for a substantial portion of the renovation budget.
Flooring Installation
Flooring costs depend largely on the material chosen.
Popular flooring options include:
- Vinyl flooring
- Ceramic tiles
- Porcelain tiles
- Engineered wood
- Natural stone
Premium materials generally require higher installation costs and maintenance considerations.
BTO Renovation vs Resale Flat Renovation
BTO Renovation Costs
BTO renovations are generally more affordable because fewer structural modifications are required.
Typical BTO projects focus on:
- Carpentry
- Lighting
- Interior design
- Storage solutions
- Minor flooring upgrades
Resale Flat Renovation Costs
Resale flats often require substantial upgrading work.
Additional costs may include:
- Hacking existing structures
- Replacing old plumbing
- Electrical rewiring
- Wall repairs
- Waterproofing
As a result, resale renovations are often significantly more expensive than BTO renovations.
Hidden Costs Many Homeowners Overlook
Many renovation budgets fail to account for additional expenses such as:
- Temporary accommodation
- Appliance purchases
- Moving expenses
- Permit applications
- Professional cleaning
- Unexpected repairs
Setting aside 10% to 15% of your renovation budget as a contingency fund is often recommended.
How to Reduce Renovation Costs
Homeowners can often save money by:
- Retaining the existing layout
- Avoiding unnecessary hacking works
- Limiting custom carpentry
- Comparing multiple quotations
- Choosing durable mid-range materials
- Renovating in phases when appropriate
The goal should not be to find the cheapest contractor but to achieve the best balance between quality, durability, and value.
