Is Vinyl Flooring Waterproof? Kitchens, Bathrooms and Singapore Humidity
Quick answer (TL;DR)
- Most SPC and LVT planks are 100% waterproof. The planks will not swell or rot.
- Water can still get under a floating floor through gaps at the edges.
- Vinyl is great for kitchens and living areas, but tiles are better for showers and bathrooms.
- Wipe spills, seal edges in wet areas and avoid flooding the floor when mopping.
Is vinyl flooring waterproof?
Yes. Most modern vinyl flooring, including SPC and LVT, is waterproof. The planks are made from PVC and, for SPC, a limestone composite core, so they do not absorb water, swell or rot. A spilled drink or a wet mop will not damage the plank itself. This is one of the main reasons vinyl is so popular in Singapore.
Waterproof vs water-resistant: what is the difference?
Waterproof means the material does not absorb water at all, even if it sits on the surface for a long time. Water-resistant means it can handle spills for a short time but may be damaged if water stays.
| Flooring | Waterproof or water-resistant? |
|---|---|
| SPC vinyl | Waterproof |
| LVT vinyl | Waterproof |
| WPC vinyl | Waterproof planks, softer core |
| Laminate | Water-resistant only |
| Solid timber | Not waterproof |
Can water get under vinyl flooring?
Yes, and this is the part many people miss. Click-lock vinyl is a floating floor. The planks are waterproof, but water can seep in through the expansion gap at the walls or through damaged joints. If water sits under the floor, it can cause odours, mould or loosen glue on the subfloor.
To prevent this:
- Seal edges with silicone in kitchens and near doors to wet areas.
- Fix leaks, such as aircon drips or sink pipes, quickly.
- Do not flood the floor with water when cleaning.
- If there is a large flood, lift the affected planks and let the subfloor dry.
Is vinyl flooring good for kitchens?
Yes. Vinyl is an excellent kitchen floor in Singapore. It is waterproof, comfortable to stand on while cooking, and easy to clean. Use planks with a 0.3mm or thicker wear layer, seal the edges along cabinets, and place a mat in front of the sink.
Can you use vinyl flooring in bathrooms?
You can, but it is usually not the best choice for wet bathrooms in Singapore homes. Showers create standing water, and bathroom floors rely on waterproofing membranes and floor traps. For HDB flats, HDB’s building works guidelines also set specific rules for bathroom floor works. Tiles remain the safer option for shower areas. Vinyl can work in a dry powder room or guest toilet.
How does vinyl handle Singapore’s humidity?
Very well. Singapore’s relative humidity often sits above 80%. Wood-based floors such as laminate and solid timber absorb this moisture and can swell, cup or warp. Vinyl does not absorb moisture from the air, so it stays flat and stable all year.
Vinyl does expand slightly with heat. That is why installers leave a small gap at the walls and why floor-to-ceiling windows with strong afternoon sun may need blinds. Compare vinyl with other floors in vinyl vs laminate vs tiles.
Which vinyl type handles water best?
SPC is the most stable when it comes to water and temperature. Its rigid stone-composite core does not swell and moves very little. Thick LVT is also waterproof and gives very realistic finishes. Read SPC vs LVT vs WPC to choose the right one.
Frequently asked questions
Is SPC vinyl flooring 100% waterproof?
Yes, SPC planks are fully waterproof. They will not swell or rot when wet. The only risk is water seeping under the floor through gaps, which is why edges should be sealed in wet areas.
Can I mop vinyl flooring?
Yes. Use a damp, well-wrung mop and a pH-neutral cleaner. Avoid soaking the floor or using steam mops, which can push water and heat into the joints.
Can vinyl flooring be used in HDB bathrooms?
It is not recommended for shower areas. Tiles are the safer choice because bathrooms need waterproofing membranes and floor traps, and HDB has specific rules for bathroom floor works.
What happens if vinyl flooring gets flooded?
The planks themselves will survive, but water trapped underneath must be removed. Lift the affected planks, dry the subfloor fully, and then click the planks back into place.
