Can You Use Subflooring as Your Regular Floor?

In most cases, subflooring cannot be used as a regular floor. Although it provides a base for installing most floor coverings, it is only intended for that purpose. Here are some reasons why subflooring is not usually suitable as a regular floor:

1. Thin and Unfinished: Subflooring materials, such as plywood, oriented strand board (OSB), or particle board, are typically very thin and unfinished. By themselves, they are not structurally strong enough to withstand the direct impact of foot traffic or heavy furniture.

2. Rough and Uneven: Subflooring materials have a rough and uneven surface. They are not sanded or treated like finished flooring materials, so they may cause splinters or discomfort to walk on barefoot.

3. Moisture Sensitivity: Subflooring materials are susceptible to moisture damage. They are designed to provide support for the finished floor and are not treated with water-resistant coatings. Prolonged exposure to moisture from spills, humidity, or cleaning can lead to warping, buckling, or mold growth.

4. Unattractive Appearance: Subflooring panels are not visually appealing and are not meant to be the final flooring surface. They are typically unfinished or have a rough texture that is not aesthetically pleasing.

5. Building Codes: Building codes and regulations usually specify the types of materials and layers required for flooring systems. Subflooring materials are not designed or approved as the final floor covering in residential or commercial buildings.

However, there are specific engineered wood or vinyl flooring products designed to be installed directly on subfloors without the need for additional underlayment. These flooring products often feature a thicker and more durable construction with built-in moisture resistance. Before installing any flooring material directly on subflooring, it is essential to consult the product specifications and ensure that the subflooring is in good condition, flat, and properly leveled.
