What is the best waterproof laminate flooring for NB kitchens and bathrooms?

For NB kitchens and bathrooms, true waterproof laminate with a rigid polymer or plastic composite core is the best option — but honestly, luxury vinyl plank (LVP) outperforms even waterproof laminate in wet areas and deserves serious consideration. If you are committed to laminate specifically, look for products marketed as "waterproof" rather than merely "water-resistant," as the distinction matters enormously in Maritime moisture conditions.

Traditional laminate uses an HDF (high-density fibreboard) core that swells when exposed to moisture. Water-resistant laminate improves on this with wax-impregnated HDF and sealed joints, but the core is still wood-based and will eventually fail if moisture reaches it. True waterproof laminate replaces the HDF core entirely with a rigid plastic or polymer composite — similar to what you find in SPC (stone polymer composite) luxury vinyl plank. These products look and feel like laminate on the surface but handle water like vinyl underneath.

In NB kitchens, where spills, splashes from the sink, and dishwasher leaks are common, waterproof laminate handles day-to-day moisture well. However, NB kitchens in older homes (pre-1970s housing stock is common across the province) often have subfloor conditions that introduce moisture from below — especially in homes with crawl spaces or pier foundations where Maritime ground moisture migrates upward. If your subfloor shows moisture readings above 12% on a pin meter, address the moisture source before installing any laminate.

For bathrooms, even waterproof laminate has limitations. Bathrooms generate sustained humidity from showers and baths, and NB's already-high summer humidity compounds this. Water can pool around toilets, tubs, and vanities for extended periods. While waterproof laminate resists surface water, the joints remain vulnerable points where moisture can work its way underneath over time. Most flooring professionals in NB will recommend porcelain tile ($9-$20/sq ft fully installed) or quality LVP ($5-$12/sq ft fully installed) for bathrooms over any laminate product.

If you do choose waterproof laminate for a bathroom, ensure the subfloor is completely level (use self-levelling compound at $2-$4/sq ft if needed), apply silicone caulk around the perimeter instead of relying solely on expansion gaps, and seal all transitions to adjacent flooring with waterproof transition strips. These extra steps add $1-$2/sq ft but significantly improve long-term performance.

Waterproof laminate typically costs $4-$6/sq ft for materials in NB, plus $2-$4/sq ft for installation, putting a kitchen floor (150-250 sq ft) in the $1,500-$2,500 range fully installed. Compare this to quality SPC luxury vinyl plank at similar pricing but with genuinely superior waterproof performance. For kitchens, waterproof laminate is a reasonable choice. For bathrooms, tile or LVP is the smarter long-term investment in NB's Maritime climate.
