Bathrooms are small but among the most technical rooms to renovate — waterproofing, tiling and plumbing all have to be right, because mistakes here are expensive to fix later. Here's what an HDB bathroom renovation involves in 2026.
What's involved
- Hacking existing tiles and fittings (for a full reno).
- Waterproofing — the most important hidden step.
- Tiling — floor and walls, with proper falls to the drain.
- Plumbing & fittings — WC, basin, mixer, shower, accessories.
What drives bathroom cost
What pushes bathroom cost up
Never skip or cut corners on waterproofing. It's a small fraction of the cost but the single biggest cause of leaks, disputes with neighbours, and re-do bills. Always confirm it's in the quote.
Overlay or full hack?
Overlaying new tiles over old saves time and cost but adds height and isn't always suitable. A full hack lets us re-waterproof properly — we advise per case.
How long does a bathroom take?
Typically 1–2 weeks including waterproofing cure time, sequenced with other wet works.
Do you handle the plumbing and electrical?
Yes — one team handles tiling, waterproofing, plumbing and electrical for the bathroom.

The direct-contractor advantage: we're the renovation contractor, not a middleman — our own team does the work, so you're not paying a designer's markup on labour. More of your budget goes into materials and finishes.
