Filled vs unfilled travertine: which should you use?
Filled travertine has its natural holes packed with a cement or resin fill for a smooth, easy-clean surface, which suits interior floors, walls and baths. Unfilled travertine keeps its open pores for a rustic, textured look, which is why tumbled or unfilled travertine is often chosen for patios and pool decks.
What does 'filled' mean?
Travertine forms around mineral springs, and escaping gas leaves natural voids. At the factory, those voids can be filled with a cement-based or resin filler tinted to match the stone. The result is a flat, closed surface.
Fills are not permanent. Over years, some can loosen or pop out, especially on floors. They are easy to refill with a matching filler.
What are the common travertine finishes?
- Honed: smooth and matte. The classic interior choice, usually filled.
- Polished: glossy, usually filled. Best on walls and low-traffic floors.
- Tumbled: rounded edges and a worn, old-world texture. Often unfilled.
- Brushed: a soft, textured surface between honed and tumbled.
The cut matters too. Vein-cut shows linear bands. Cross-cut shows a cloudier, more random pattern.
Which works best indoors?
Filled and honed is the easiest to live with in kitchens, baths and living areas. It is smooth underfoot, simple to clean, and has better grip than polished. Unfilled travertine indoors can trap crumbs and dirt in the holes.
Which works best outdoors and around pools?
Tumbled or brushed travertine pavers, often unfilled, are popular for patios and pool decks. The texture adds grip and the light color stays relatively cool underfoot. Resin fills can discolor in strong sun, so cement fills or unfilled stone are the more common exterior choice.
In the Northeast, freeze-thaw is the real test. Choose dense, exterior-grade travertine, install over a well-draining base, and seal it.
How do you care for travertine?
Travertine is calcium carbonate, like marble, so acids etch it. Use a pH-neutral cleaner, seal with a penetrating sealer, and test absorption with a few drops of water once a year. Outdoors, rinse off pool chemicals and salt.
Tribeca Stone carries travertine for interiors and exteriors and can send samples out the same day in New York. Or come compare filled and unfilled in person at our Tribeca showroom.
Questions we hear
Is travertine good for a kitchen floor?
Yes. Filled, honed travertine is a durable, warm-looking kitchen floor. Seal it and wipe up acidic spills.
Will the fill fall out of travertine?
Some fill can loosen over time, mostly in high-traffic areas. It is easy to patch with a color-matched filler.
Can unfilled travertine be filled after installation?
Yes. Installers often fill open voids with grout during grouting, or with a matching filler afterward.
Does travertine etch?
Yes. It reacts with acids like lemon, vinegar and many bathroom cleaners. A honed or tumbled finish hides etching best.
