Natural stone has a depth and variation that no two pieces share. It also behaves differently from porcelain and ceramic, so it's worth knowing what you're signing up for.
Common types
- Marble is classic for bathrooms, with soft veining in white, gray, green and black. It's relatively soft and reacts to acids, so it can etch.
- Travertine has a warm, earthy look with natural holes, which are usually filled at the factory. Finishes range from polished to tumbled.
- Slate is dark and textured with natural cleft surfaces that grip well underfoot.
- Limestone is soft and muted, with a calm, matte look.
- Granite is very hard and durable, more common on countertops than as tile.
How stone differs from porcelain
- It's porous. Most stone absorbs liquids and needs a penetrating sealer, then resealing over time.
- It can etch. Acidic things like citrus, vinegar and some cleaners can leave dull marks on marble, travertine and limestone, even when sealed.
- Every piece varies. Color and veining change from tile to tile and from one batch to the next. Mixing tiles from several boxes during installation helps the variation look natural.
Where stone works well
- Bathroom floors and walls, including shower walls when properly sealed
- Fireplace surrounds
- Entry floors in honed or tumbled finishes
Where to be careful
- Polished stone on wet floors can be slippery. Honed, tumbled or textured finishes are safer.
- Kitchen backsplashes behind the stove and sink see grease and acids. Seal well and wipe spills quickly.
Caring for stone
- Clean with a pH-neutral stone cleaner, never vinegar or harsh acids.
- Reseal on the schedule the sealer manufacturer recommends; a simple water drop test shows when it's time.
- Use mats at entries to keep grit from scratching the surface.
Stone-look porcelain
If you love the look but not the upkeep, marble-look and slate-look porcelain have come a long way. They don't need sealing and resist stains and etching.
