Ultimate Waterproof WPC Vinyl Plank vs Influence Waterproof Vinyl Plank Flooring

Both are waterproof click-lock vinyl with a 20 mil wear layer and a lifetime residential warranty, so the wear surface is a wash. The Ultimate is the heavier build: a 12 mm WPC plank with a 1 mm attached pad and 72-inch boards, which gives a more solid feel underfoot and fewer seams across a room. The Influence is a 5.5 mm SPC plank with shorter 48-inch boards and a 1.5 mm IXPE pad rated 63 dB IIC, so it is thinner but quieter and stiffer under load. Buyers who want a substantial, long-plank floor for a main living area lean Ultimate; buyers who want a rigid, dent-resistant plank for basements, rentals or busy pet households lean Influence.

• Choose the Ultimate if you want long 72-inch planks, a thick 12 mm WPC body and a solid, quiet feel in a main living space.
• Choose the Influence if you want a rigid SPC core that resists dents, a higher-rated attached pad and shorter planks that are easier to handle on a DIY install.
