Choose Cost-Effective Tiles
Use designer tiles only for feature walls; stick to plain tiles for other areas.
Bathrooms are one of the most essential and heavily used spaces in every HDB flat. Whether it’s your morning routine, evening wind-down, or hosting guests, a clean, functional, and well-designed toilet makes a huge difference to daily living. For resale flats, toilet renovations are often non-negotiable due to aging waterproofing and outdated fittings. Even new BTO flats may require upgrades for comfort and style.
So, how much does it cost to renovate 2 toilets in Singapore in 2025–2026, and what should homeowners plan for? This guide covers the full breakdown of costs, services included, factors that influence pricing, money-saving tips, splurge-worthy upgrades, and frequently asked questions.
Renovating both toilets in your HDB flat is not just about aesthetics. Here are the key reasons homeowners invest in this upgrade:
Old toilets often suffer from leaks and damaged waterproofing, which can lead to water seepage and costly HDB complaints.
Modern sanitary fittings, proper ventilation, and new tiles improve hygiene and make bathrooms easier to clean.
With clever layouts and storage carpentry, even small HDB bathrooms can feel spacious and clutter-free.
Families with elderly parents may require grab bars, slip-resistant flooring, and wider doorways for safety.
Transform your toilet with modern designs like hotel-inspired bathrooms, minimalist Japandi looks, or luxurious spa vibes.
Like kitchens, toilets are deal-makers. Well-renovated bathrooms can justify higher asking prices during resale.
Here’s a breakdown of the common services involved in renovating two HDB toilets and their estimated costs in Singapore:
Removal of old tiles, sanitary fittings, shower screens, and storage.
Critical for preventing water leakage into your neighbour’s ceiling. Waterproofing is done in layers, with mandatory 3-day HDB water ponding tests.
Depends on the choice of tiles. Homogeneous tiles are standard; patterned or designer tiles raise costs.
Includes replacing pipes, installing toilet bowls, sinks, taps, mixers, shower sets, and concealed piping if required.
Adds a clean division between wet and dry zones, preventing water from splashing everywhere.
Custom storage cabinets, vanity counters, and mirror cabinets.
Essential for both functionality and ambience — mirrors, shelving, LED lights, and exhaust fans.
Before diving into renovation, here are key factors every homeowner should plan for:
Waterproofing, plumbing rerouting, and hacking require HDB approval. Your interior designer/contractor will apply for these permits.
Each toilet takes 3–6 weeks. Renovating two toilets together usually requires 6–8 weeks. Always buffer extra time for inspections.
If both toilets are being renovated simultaneously, arrange for temporary bathroom access (some IDs provide portable solutions).
Toilets are one of the highest cost-per-square-foot areas. Always buffer 10–20% for last-minute add-ons like rain showers or heated bidets.
Young couples may prioritise aesthetics, while families with elderly parents need safety features like anti-slip tiles.
Imported fittings or custom vanities may take weeks to arrive. Order early to avoid delays.
Year-end and Chinese New Year holidays often slow down works.
Older resale flats require full waterproofing and new piping, which adds cost.
A light refresh (replacing fittings) is cheaper than a full gut renovation with new tiles.
Simple homogeneous tiles cost less, while patterned, marble-look, or mosaic tiles can double expenses.
Basic sets are affordable, but designer brands (Grohe, Kohler, Toto) can push costs up.
Vanity counters and storage units raise costs but improve space efficiency.
Rain showers, bathtubs, concealed cisterns, or built-in bidet seats increase both cost and installation time.
A full-service ID provides design, coordination, and aftercare, while a contractor-only route may cost less but requires more self-management.
Use designer tiles only for feature walls; stick to plain tiles for other areas.
Avoid shifting toilet bowls, sinks, or shower areas unless necessary. This saves on plumbing costs.
Mirrors, shelving, or even taps in good condition can be reused.
Bundled purchases from stores like Hoe Kee or Heritage Bathroom save hundreds.
For dry areas, vinyl is cheaper and easier to maintain compared to tiles.
Compare at least 3–5 IDs to avoid overpriced quotations.
Don’t cut corners here. Fixing a leak later will cost far more than doing it properly upfront.
A must-have investment for long-term durability
Adds hotel-like luxury to your daily routine.
Durable and resistant to water damage.
Smart storage keeps bathrooms neat and clutter-free.
Soft-close seats, water-saving flush, and durable fittings last longer.
Keeps the wet and dry areas separated for easier cleaning.
If space allows (usually 5-foot bathtubs), it’s a worthwhile splurge for relaxation.
On average, $16,000–$25,000 for mid-range works. Premium designer toilets can go beyond $40,000.
Yes, it’s possible if space allows. A standard 5-foot bathtub can fit into most HDB master bathrooms, but waterproofing and structural approval are required.
Around 6–8 weeks, depending on scope and materials. Always buffer 1–2 weeks for inspections and defect touch-ups.
It’s challenging since you’ll have no functional toilets for weeks. Many homeowners stay with relatives or rent a short-term unit.
Minimalist Japandi, industrial concrete, hotel-inspired luxury, and soft neutral palettes are popular among homeowners.
Yes. Banks offer renovation loans up to $30,000, repayable in 1–5 years. This helps ease cashflow for bigger projects.
Waterproofing. Cutting costs here can lead to leaks, HDB disputes, and costly repairs.
With proper works, waterproofing can last 10–15 years before issues arise.
Toilets may be small in size but renovating them is one of the biggest investments in your HDB flat. From waterproofing and tiling to fittings and carpentry, every choice impacts both cost and comfort. By knowing where to save and where to splurge, you can achieve stylish, functional bathrooms that last for years to come.
