Prefinished or Unfinished Wood Flooring – Which Should You Choose?

Factory-finished (prefinished) and site-finished (unfinished) wood flooring have been compared and discussed for decades. The reality is that neither option is absolutely better than the other. If one truly outperformed the other in every aspect, it would have already taken over the market. Instead, both continue to exist because they cater to different needs, styles, and homeowner preferences.

When choosing between them, it is not about right or wrong, but rather about which fits your lifestyle, design vision, and budget. Here are the main differences to keep in mind:

• Prefinished flooring: Comes ready from the factory with stain and protective layers applied. It allows for a quicker, cleaner installation and provides a durable finish right away.
• Unfinished flooring: Installed in raw form and finished on-site. This gives more flexibility in colour choices, custom stains, and finishes, ensuring a completely tailored look.

Both options have their advantages and limitations, and understanding them will help you make an informed choice rather than simply following trends.

Prefinished Floors

Prefinished floors, also called factory-finished floors, arrive with the protective coating already applied in the factory. This means they are ready for use immediately after installation. While this offers many benefits, there are also some downsides to consider.

Durability

Factory coatings are exceptionally strong. Most prefinished floors use polyurethane lacquers, but some manufacturers add aluminium oxide, which is even more durable and can only be applied in a controlled factory setting. Warranties for these finishes often last 25 years or more, sometimes even up to 50 years. By contrast, a site-applied finish usually has a warranty of 5 years or less.

Refinishing

The durability of aluminium oxide coatings comes at a cost. If the floor ever needs sanding, removing the coating can be difficult and time-consuming. This is particularly risky for engineered floors with thin veneers, where using coarse sanding grits may permanently damage the boards.

Repairs

One major drawback of prefinished floors is that the factory finish cannot be repaired. If damage occurs, the only solution is to replace the affected planks, since the finish cannot be reproduced on-site.

Installation

Prefinished flooring is easy to install and ready to use immediately. There is no need for sanding, staining, or finishing, and no waiting time for drying or curing.

Cleaning and Maintenance

The durable coating makes prefinished floors highly resistant to scratches, dents, and general wear. However, because no finish is applied after installation, the seams between boards remain unsealed. This can trap dirt and dust and leave the floor vulnerable to moisture or liquid spills. Extra care is required when cleaning, especially with water.

Health Benefits

Many modern finishes release Volatile Organic Compounds (VOCs), which can be harmful and even carcinogenic. With prefinished floors, however, the finish is fully cured in the factory, meaning there is no VOC off-gassing in your home.

Bevels and Appearance

Because prefinished floors do not undergo sanding after installation, the floor will only be as level as the subfloor beneath it. To mask minor unevenness, manufacturers often add bevelled edges. While bevels can give the floor a distinct look, they serve no practical purpose other than disguising height differences. Some homeowners love the look, while others prefer a smoother surface.

Unfinished Flooring

Unfinished flooring is installed in raw form and then sanded, stained, and finished on-site. Although this method is usually more expensive and time-consuming, many homeowners prefer it because of the flexibility and customisation it offers. Let’s take a closer look at its main features.

Durability

On-site finishes cannot match the toughness of aluminium oxide coatings found on prefinished floors. However, even the strongest factory finishes will eventually wear down and require sanding. While unfinished floors may not have the same extreme durability, they offer more long-term practicality since they are easier to refinish when the time comes.

Refinishing

The true beauty of unfinished flooring lies in its refinishing potential. No matter how old or worn the floor becomes, you can sand it back, apply a fresh finish, and restore it to its original appearance. Each time, you can choose a different stain, colour, or finish, allowing you to transform the look of your home whenever your style changes. This level of personalisation is something prefinished floors cannot offer.

Repairs

Site-finished floors are much easier to repair. If a section gets damaged, you can fix the area and recoat it, blending it seamlessly with the rest of the floor. Unlike prefinished flooring, there is no need to replace entire planks because the factory finish is unavailable.

Installation

Installing unfinished floors is more complex, requires skilled professionals, and takes longer than laying prefinished boards. Each coat of stain or finish must dry properly, which extends the project timeline. The upside is a smooth, continuous finish with no gaps or factory bevels.

Cleaning and Maintenance

Because unfinished floors are finished after installation, the entire surface, including seams, is sealed. This prevents dirt and moisture from seeping between boards. While the finish may not be as strong as factory coatings, it has no weak spots. Cleaning is straightforward, and if the surface looks dull, you can often buff and recoat instead of full sanding.

Health Considerations

On-site finishes may contain VOCs (Volatile Organic Compounds), which can negatively impact indoor air quality. Fortunately, there are low-VOC and natural finishes available that contain little to no harmful chemicals. The trade-off is that these eco-friendly products usually require more frequent maintenance and may not last as long as synthetic finishes.

Unfinished Solid Oak Flooring

The main advantage of unfinished solid oak flooring is that it gives the property owner complete freedom of choice. You decide on the stain and finish, ensuring the floor perfectly matches your interior design and lifestyle. While in domestic settings, the protective strength of the finish may not always be critical, the colour and appearance certainly are.

Unlimited Design Possibilities

Modern finishing products provide an unlimited palette of colours and effects. Whether you prefer deep and rich dark browns, elegant whitewashed or limed looks, warm reddish tones, subtle greys, or even more daring styles with black, gold, or silver accents, unfinished oak can be transformed to suit your vision. With this type of flooring, your imagination sets the limit.

Durability and Thickness

Unfinished oak planks are typically available in 20 mm thickness, making them thicker than most prefinished boards. This additional thickness means they can be sanded multiple times and treated with high-performance finishes for long-lasting protection. Products such as Bona Traffic HD and Junckers HP Commercial are specifically designed for high-traffic areas and provide superior durability.

Comparison with Prefinished Oak

By contrast, prefinished solid oak planks are usually around 18 mm thick and come ready for installation. They save time and effort during fitting, but they lack the flexibility of unfinished oak when it comes to personalisation and refinishing.

Which One Should You Choose?

Both prefinished and unfinished wood flooring have clear advantages, and the best choice depends on your priorities, lifestyle, and design goals. Here’s a quick comparison to guide your decision:

• Choose Prefinished Flooring if: You want a quicker installation, immediate use, a durable factory-applied coating, and minimal disruption during the process. It’s ideal for those who value convenience and low maintenance.
• Choose Unfinished Flooring if: You prefer full control over the colour and finish, a seamless look with no bevels, and the option to refinish and transform the floor multiple times in the future. It’s the perfect solution for homeowners who want a fully customised result.

In the end, there is no universal “better” option. Prefinished floors save time and offer exceptional durability, while unfinished floors provide unlimited design flexibility and repair options. The right choice is the one that aligns with your home, your taste, and how you plan to use the space.

FAQ: Prefinished vs Unfinished Wood Flooring

Can unfinished floors be stained any colour?

Yes. One of the biggest advantages of unfinished floors is that they can be stained in almost any colour. From classic natural tones to trendy whitewashed, grey, or even bold custom finishes, the choice is unlimited.

How long do prefinished floors last?

Thanks to tough factory coatings such as polyurethane or aluminium oxide, prefinished floors often come with warranties of 25 years or more. With proper care, they can last even longer before needing refinishing or replacement.

Are unfinished floors harder to maintain?

Not necessarily. While unfinished floors may not have the ultra-durable coatings of prefinished options, they are fully sealed after installation and can be easily buffed and recoated when needed. This makes them practical for long-term use.

Which option is better for homes with children or pets?

Prefinished floors usually handle scratches and heavy wear better, making them more suitable for busy households. However, unfinished floors have the advantage of being easier to repair if damage does occur.

Is unfinished solid oak worth the extra cost?

If you want a thicker board (usually 20 mm), more refinishing opportunities, and the freedom to create a custom finish, unfinished oak is worth the investment. It’s especially valuable in period homes and spaces where design flexibility matters most.
