The two look similar in the showroom and behave differently on the floor. What actually separates them, and which rooms care.
Ceramic and porcelain are both fired clay, and in a showroom they can be hard to tell apart. The difference is density. Porcelain is fired hotter from a finer clay, so it absorbs very little water and is harder all the way through. Ceramic is softer, easier to cut, and usually kinder on the budget.
Where the difference actually matters
- Floors that get walked on hard — hallways, kitchens, entries: porcelain takes the traffic better.
- Anywhere that gets genuinely wet — shower floors and walls, bathroom floors: porcelain's low absorption is the point.
- Outdoors and unheated spaces: water that soaks into a tile and then freezes will break it. Porcelain rated for outdoor use is the safer choice.
- Walls and backsplashes indoors: ceramic is perfectly good, lighter to hang, and there is far more of it to choose from.
Through-body colour is worth knowing about
Glazed ceramic is coloured on the surface. Chip the edge of a tile and you see the pale clay underneath. Full-body porcelain carries its colour through the tile, so a chip is much less obvious. On a floor that will take a dropped pan at some point, that matters more than it sounds.
Rating, not marketing
Tile is graded for hardness and for slip resistance. A tile sold for walls is not automatically fit for a floor, and a beautiful polished tile can be genuinely dangerous in a wet bathroom. When you have a tile in mind, tell us the room and we will tell you honestly whether it belongs there.
What goes underneath decides how long it lasts
Most tile that fails did not fail as tile. It moved, because what it was stuck to moved. A floor that flexes will crack grout first and tiles second, so the substrate gets checked and prepared before anything is set — and in a shower, the waterproofing behind the tile matters more than the tile itself.
Grout is a design decision
Matching your grout to the tile makes a floor read as one calm surface. Contrasting it turns the layout into a pattern and draws the eye to every line — which is a good thing when the setting-out is square, and unforgiving when it is not. Darker grout in a busy kitchen or entry stays looking clean for longer.
