How Does Subfloor Influence Flooring Choice?

The type of subfloor you have has a strong influence on what kind of wood flooring you can install. In this case, we’re talking about solid hardwood flooring vs. engineered hardwood flooring. In this week’s blog, we’ll discuss what kind of floors work for different subflooring.

Plywood

Plywood is a very common subfloor and is usually found on the first and second floor of your home. It works equally well for solid hardwood flooring or engineered hardwood flooring, and requires no alterations to install either one!

Particleboard

Although similar to plywood, particleboard is unfortunately not usable when it comes to hardwood floors. You’ll have to tear out the particleboard and replace it with plywood in order to make it a viable subfloor for wood flooring. Once you do this, you can go with either solid or engineered hardwood.

Concrete

Concrete is a common subfloor in basements or condominiums, or if you don’t have a basement, the ground floor of your home may have a concrete subfloor. There are several stipulations for concrete subflooring that dictate what kind of flooring will work here.

If the concrete subfloor is in the basement, solid wood flooring is not advisable (you can’t nail the flooring into concrete). Another issue with is that there will almost always be a moisture problem sooner or later in the basement which will ruin a solid wood floor. Engineered hardwood floor is the only kind of wood suitable for use on a concrete subfloor in the basement.

If the concrete subfloor is at ground level, the best choice is still engineered hardwood. However, if you really want solid wood, there are a few options. First, you could install plywood over the concrete, and then install solid wood over that. Expensive, but a viable option. Alternatively, solid wood flooring can be glued to a concrete subfloor, though there are some caveats.

Overall, the best choice for concrete subfloors is usually engineered hardwood. Though solid hardwood isn’t out of the question as long as it is at ground level, it will be more expensive and time consuming to install.

How Subfloor Type Affects Sound, Comfort, and Daily Use

The type of subfloor beneath a wood floor influences more than installation requirements. It also plays a meaningful role in how the floor sounds, feels underfoot, and performs during everyday use.

Floors installed over plywood subfloors generally feel more forgiving and quieter. Because plywood has some natural flexibility, it absorbs impact better than concrete. This often results in less hollow or echoing noise when walking across the floor. Nail-down installations over plywood also tend to feel more solid, which many homeowners associate with traditional hardwood flooring.

Concrete subfloors behave differently. Concrete is rigid and does not absorb vibration, so wood flooring installed directly over it may sound louder or feel firmer underfoot. This effect is especially noticeable in large rooms or open floor plans. To reduce noise, installers typically use underlayment materials designed to dampen sound and limit vibration transfer. These layers can make a noticeable difference in comfort, particularly in multi-story homes or condominiums where sound transmission matters.

Temperature is another consideration. Concrete subfloors tend to remain cooler, which can make wood flooring feel colder during winter months. Engineered hardwood installed with an appropriate underlayment can help reduce this effect, while solid hardwood installed over a plywood layer above concrete may feel closer to floors on upper levels of the home.

Subfloor choice can also affect floor height and transitions between rooms. Adding plywood or underlayment over concrete increases the finished floor height, which may require adjustments at doorways or stair landings. Planning for these changes early helps avoid uneven transitions and tripping hazards.

Understanding how a subfloor influences sound and comfort helps set realistic expectations. While both plywood and concrete subfloors can support attractive wood floors, the experience of walking on them can differ in ways that matter long after installation is complete.
