HDB Toilet Renovation 2026: Packages, Costs & Common Pitfalls

How Much Does a Toilet Renovation Cost? Basic Refresh: $3,000–$5,000 New fixtures (toilet bowl, basin, tap), painting, and minor repairs. No hacking. Suitable for relatively new flats where tiles and waterproofing are still in good condition. Standard Renovation: $5,000–$8,000 Full hacking of existing tiles, new waterproofing, retiling (floor and walls), new vanity, shower screen, toilet bowl, and fixtures. This is what most HDB homeowners need. Premium Renovation: $8,000–$12,000+ Everything in standard, plus rain shower system, frameless shower screen, premium vanity with mirror cabinet, heated towel rack, and designer tiles. Dual Toilet Package: $9,000–$16,000 Most HDB flats have two bathrooms. Renovating both together is cheaper per unit than doing them separately because of shared mobilisation and labour costs. The Waterproofing Non-Negotiable If you're hacking any bathroom tile, waterproofing must be redone completely. This isn't an area to save money. Proper waterproofing involves applying a membrane to the floor and walls (up to at least 1.8m height), then conducting a ponding test — filling the floor with water and leaving it for 24–48 hours to confirm zero leakage. The cost is $700–$1,200 per bathroom. The cost of NOT doing it properly? Potential water damage to your downstairs neighbour's ceiling, which can easily hit $5,000–$10,000 in repairs and compensation. Common Toilet Renovation Mistakes Not checking pipe condition before hacking. Old pipes can crumble during demolition. Budget for potential pipe replacement ($500–$1,500 per bathroom). Choosing tiles that look great but are slippery when wet. Always check the slip rating. R10 or higher is recommended for bathroom floors. Forgetting ventilation. Singapore's humidity means bathrooms need proper airflow. If there's no window, install an exhaust fan during renovation, not after. Skimping on the shower screen. Cheap shower screens leak at the seals within 1–2 years. Invest in tempered glass with quality seals. Ignoring the toilet bowl trap type. HDB toilets use specific trap configurations (S-trap or P-trap) based on the plumbing layout. Your new toilet bowl must match, or it won't flush properly. Tile Selection for Bathrooms For walls, glazed ceramic tiles ($3–$8/piece) are the standard. They're waterproof, easy to clean, and come in endless designs. For floors, go with porcelain or anti-slip ceramic. Matte finishes with texture provide better grip than polished tiles. Large-format tiles (600x600mm or larger) are trending because they have fewer grout lines, which means less maintenance and a cleaner visual. However, they cost more to install due to the precision required. → Get toilet renovation quotes from $5K on Reno Research → Use our cost calculator to estimate your bathroom budget
