A straight comparison written by Singapore grout specialists — no fluff, just what you need to know before deciding.
Short answer: In Singapore, epoxy grout wins every time for wet areas.
Singapore's year-round humidity destroys cement grout within 6–12 months. Epoxy grout lasts 10–15 years with zero maintenance. The price difference pays for itself within 3 years.
Cement grout (also called sanded or unsanded grout) is the traditional grouting material used in most homes. It's made from a mix of cement, water, and sometimes sand. It's cheap, easy to apply, and comes in many colours.
The problem: cement is porous. It absorbs everything — water, soap, body oils, cooking grease. In Singapore's humidity, it also absorbs moisture from the air constantly. That's why cement grout in Singapore bathrooms turns black within months, not years.
Epoxy grout is made from epoxy resin and a hardener rather than cement. When mixed and applied, it cures into a hard, glass-like, non-porous surface. Water, soap, humidity, and bacteria cannot penetrate it.
It's been the preferred grouting material in commercial kitchens, food manufacturing plants, and hospitals for decades — precisely because it doesn't absorb liquids. For Singapore homes, it solves the black grout problem permanently.

| Mould resistance | Poor — absorbs moisture | Excellent — non-porous ✓ |
| Stain resistance | Poor | Excellent ✓ |
| Cleaning required | Weekly scrubbing | Damp wipe only ✓ |

| Suitable for Singapore humidity | No | Yes ✓ |
Singapore sits close to the equator with average humidity of 70–90% year-round. Our bathrooms are used daily with no dry season. This creates a relentless cycle of moisture exposure that cement grout simply cannot survive.
Epoxy grout short-circuits this entire cycle. Because it's non-porous, mould cannot grow in it — there's no moisture for it to live on. The grout you install stays exactly as it looks on day one.
We'll be honest: there are a few situations where cement grout is acceptable in Singapore:
For bathrooms, kitchens, and any tiled area in a lived-in home: epoxy every time.
The upfront cost of cement grout looks appealing. But in Singapore, here's what actually happens:
Total: ~$2,050 over 5 years
Total: $800 over 5 years ✓
Over 5 years, epoxy grout at the same upfront price is actually 60% cheaper. And the grout still looks great.
At Grout.sg, we carry 50+ matte epoxy colours. The most popular choices for Singapore homes:
We bring samples to your home so you choose in natural light, against your actual tiles, before we start any work.
For Singapore homes: choose epoxy grout for all wet areas, full stop.
The humidity here is too extreme for cement grout to last. The cost difference is recovered within 3 years and you save years of scrubbing. If you're regrouting anyway, do it once properly with epoxy.

Yes, for all wet areas. Singapore's year-round humidity causes cement grout to turn black within 6–12 months. Epoxy grout is non-porous and lasts 10–15 years with no maintenance.
Epoxy costs $7–$15/sqft vs $2–$4/sqft for cement upfront. But over 5 years, epoxy is cheaper because cement needs repeated resealing and regrouting.
No. Old cement grout must be fully removed first. Epoxy applied over cement grout will not bond and will fail within months.
10–15 years in Singapore conditions. The non-porous surface means humidity and daily use don't degrade it — compared to 1–3 years for cement grout.
