Bathroom Renovation Budget Singapore: Real 2026 Costs and Common Mistakes
Please note: Costs, loan amounts, tenures and timelines mentioned here are indicative estimates based on publicly available information at the time of writing. Your actual figures depend on the licensed lender's assessment of your profile and prevailing MAS rules.
Bathrooms are the smallest rooms in most Singapore homes but among the most expensive to renovate. Hacking, waterproofing, tiling and sanitary fittings all need to be done properly the first time — leaks and cracked tiles are painful to fix later. Here's what a realistic 2026 bathroom renovation actually costs.
Key takeaways
- A full HDB bathroom overhaul typically costs S$4,500–S$9,000 per bathroom.
- Waterproofing is not optional and represents around 10–15% of the bathroom cost.
- Vanity, toilet bowl, shower mixer and rain shower usually add S$1,500–S$3,500 for mid-range brands.
- The biggest hidden cost is bathroom door frame replacement in older resale flats.
What a bathroom renovation actually includes
A complete bathroom renovation covers hacking of existing tiles and sanitary ware, waterproofing membrane, screeding, wall and floor tiling, plumbing and electrical rework, and installation of new sanitary fittings.
Waterproofing is applied to the floor and up the walls in wet areas. Skipping this to save cost is the leading cause of leaks to the unit below in HDB flats — and can trigger costly BSC repair claims.

Step-by-step
- 1
Decide overhaul vs partial refresh
A cosmetic refresh (new mixer, resealing, painting) can cost under S$1,500. Full hacking triggers waterproofing and all downstream costs.
- 2
Confirm HDB permits
Hacking of bathroom walls and replacing floor waterproofing require HDB permits, handled by your registered contractor.
- 3
Choose sanitary ware first
Model dimensions dictate plumbing point positions. Locking these in early avoids costly variations.
- 4
Insist on full waterproofing testing
A 24-hour ponding test after waterproofing is standard. Ask your contractor to demonstrate it.
- 5
Reserve 10% contingency
Old resale flats often reveal rusted door frames or hidden pipe corrosion once hacking begins.
