Hiring a direct tiling contractor in Singapore for your HDB or condo saves you the 20-30% markup typically charged by Interior Design (ID) firms. Complete floor hacking and retiling generally costs between $8 to $15 per square foot (psf), while overlaying new tiles on top of existing ones is cheaper and faster, costing $5 to $9 psf.
Why Go Direct for Tiling Works?
Tiling is considered “wet works,” which is the messiest, most complex, and most expensive phase of any renovation.
By hiring a direct tiling contractor like Hock Star, you are dealing directly with the master masons. This guarantees:
- No Middleman Markup: You pay factory and direct-labor rates.
- Faster Problem Solving: If a water pipe is in the way or the concrete screed is uneven, the direct contractor solves it on the spot.
- Strict HDB Compliance: Direct contractors handle their own HDB hacking permits and Haulage/Debris clearance directly.
Hacking vs. Overlay: Which is Better?
Before you select your beautiful porcelain or homogeneous tiles, you must decide whether to hack the old floor or overlay the new tiles.

1. Hacking (Demolition & Re-screeding)
- Best For: Resale HDBs over 10 years old, or bathrooms where waterproofing membranes have failed.
- Cost: High. Requires an HDB permit, heavy debris haulage, and takes 1-2 weeks.

2. Overlaying (Direct Application)
- Best For: New BTOs (where you don’t like the HDB-provided tiles) or well-maintained resale flats.
- HDB Rules: You can only overlay if the total floor thickness does not exceed 50mm, and you cannot overlay more than once.
Frequently Asked Questions (FAQ)
Does HDB provide free cement screed for BTO flats?
Yes, if you opted out of the Optional Component Scheme (OCS) for flooring, HDB allows you to appeal for free cement screeding (up to 40mm thick) for your living room and bedrooms.
How much does it cost to renovate two HDB bathrooms?
For a full hack, waterproofing, and retiling of two standard HDB bathrooms, expect to pay a direct contractor between $6,000 to $9,000.

Wet works and tiling form the permanent foundation of your home. Whether you choose to completely hack an old resale floor or efficiently overlay a new BTO, working with a direct tiling contractor ensures superior workmanship without the bloated interior design markups.
