Linoleum kitchen flooring has come back in fashion as an environmentally friendly product. Linoleum is often confused with plastic vinyl because they both come in sheet form. But vinyl is made from synthetics, while linoleum consists of natural materials—it’s a felt or canvas coated with linseed oil, cork, and resins. The Latin root of the word linoleum means flax or linen combined with oil. Linoleum kitchen flooring comes in plain or decorative patterns, including ones that resemble marble.
