Do I need a specialist underlay for my bathroom flooring?
Standard underlay will quickly degrade in high-moisture environments. Specialist bathroom underlay provides a crucial moisture barrier, protecting your subfloor from damp, surface spills and splashes, all of which are inevitable in bathrooms. It also acts as an acoustic layer, providing essential stability and preventing your planks from moving or separating.
Which underlay is best for LVT and vinyl in the bathroom?
Look for three key features: high density, low thickness, and a waterproof rating. Vinyl needs a rigid foundation to keep the click system secure. To ensure longevity, choose an underlay with an integrated damp-proof barrier that can withstand high humidity and wet floors.
Does underlay help with noise and warmth in a bathroom?
A high-density, quality underlay significantly improves the acoustics of your bathroom, reducing the hollow, noisy sound often associated with LVT or laminate on a hard subfloor. It also adds a crucial thermal layer, making your bathroom floor feel warmer and softer underfoot—a welcome luxury on a cold morning.
