What is the difference between filled and unfilled travertines?

Dec 18, 2025

Hey there! As a travertine supplier, I often get asked about the difference between filled and unfilled travertines. It's a topic that can seem a bit confusing at first, but once you understand the ins and outs, it becomes a lot clearer. So, let's dive right in and explore what sets these two types of travertines apart.

What is Travertine?

Before we get into the filled vs. unfilled debate, let's quickly go over what travertine is. Travertine is a type of sedimentary rock that forms around mineral springs, especially hot springs. It's composed mainly of calcite, a form of calcium carbonate. Over time, the minerals in the water precipitate out and build up in layers, creating the unique patterns and textures that travertine is known for.

Travertine has been used in construction and design for thousands of years. You can see it in ancient buildings like the Colosseum in Rome, and it's still a popular choice today for everything from countertops and floors to outdoor paving and wall cladding.

Filled Travertines

Filled travertines are travertine stones that have had their natural pores and cavities filled with a resin or a similar material. This process is usually done at the quarry or during the fabrication process. There are a few reasons why people choose filled travertines:

Appearance

One of the main benefits of filled travertines is their smooth and consistent appearance. The filling material helps to create a more uniform surface, which can be especially appealing for indoor applications like flooring and countertops. When you walk on a filled travertine floor, you won't have to worry about tripping over any uneven spots or getting dirt and debris stuck in the pores.

Durability

Filling the pores also makes the travertine more durable. The resin acts as a reinforcement, making the stone less likely to crack or chip. This is particularly important in high-traffic areas where the stone will be subjected to a lot of wear and tear.

Ease of Maintenance

Cleaning and maintaining filled travertines is generally easier than unfilled ones. Since the pores are filled, there are fewer places for dirt and grime to accumulate. You can simply wipe the surface with a damp cloth or use a mild cleaner to keep it looking its best.

However, there are also a few drawbacks to filled travertines. The filling material can sometimes discolor over time, especially if it's exposed to sunlight or harsh chemicals. Additionally, some people prefer the natural look of unfilled travertines and find the filled ones to be a bit too artificial.

Unfilled Travertines

Unfilled travertines, as the name suggests, are travertine stones that have not had their pores filled. They retain their natural, porous texture, which gives them a more rustic and organic look. Here are some of the advantages of choosing unfilled travertines:

Natural Beauty

The natural pores and cavities in unfilled travertines are part of what makes them so unique. They add character and depth to the stone, creating a one-of-a-kind look that you won't find with filled travertines. Unfilled travertines are often used in outdoor applications like patios and pool surrounds, where their natural beauty can be fully appreciated.

Breathability

Travertine is a porous stone, and leaving the pores unfilled allows it to "breathe." This can be beneficial in areas where moisture is a concern, such as bathrooms and kitchens. The pores can help to absorb and release moisture, reducing the risk of mold and mildew growth.

Cost

Unfilled travertines are generally less expensive than filled ones. Since they don't require the additional step of filling the pores, the production cost is lower, and this savings is often passed on to the consumer.

On the downside, unfilled travertines can be more difficult to clean and maintain. The pores can trap dirt and debris, and it may be necessary to use a special cleaner or a pressure washer to keep them looking clean. They are also more prone to staining, so it's important to seal them regularly to protect them from spills and other contaminants.

Which One Should You Choose?

So, now that you know the difference between filled and unfilled travertines, which one should you choose? Well, it really depends on your personal preferences and the specific application. Here are some factors to consider:

Location

If you're using the travertine indoors, especially in a high-traffic area like a hallway or a living room, filled travertines may be a better choice. They offer a more durable and low-maintenance option. On the other hand, if you're using the travertine outdoors or in a more rustic setting, unfilled travertines can add a touch of natural beauty and charm.

Style

Think about the overall style of your space. If you prefer a modern and sleek look, filled travertines may be more suitable. If you're going for a more traditional or natural look, unfilled travertines are a great option.

Budget

As mentioned earlier, unfilled travertines are generally less expensive than filled ones. If you're on a tight budget, unfilled travertines can be a cost-effective way to get the look of travertine without breaking the bank.
