Vinyl is flooring that comes in large, continuous, flexible sheets. A vinyl sheet floor is completely impermeable to water, unlike vinyl floor tile, which comes in stiff tiles, and vinyl planks, which come in interlocking strips. It is sometimes called linoleum after a similar product of different (oiled linen) chemical composition.

Vinyl flooring is extensively used because it is water-impervious, fairly durable, adjustably resilient and insulating, easy to install, available with a variety of appearances, and inexpensive.
