Porcelain vs Ceramic vs Natural Stone Tiles

Three materials, three genuinely different sets of behaviour. The differences are not marketing, they change what the tile can do and what you have to do to look after it.

Porcelain

Made from a finer clay and fired at higher temperature than ceramic, which produces a much denser tile.

Water absorption is very low, which is the property that matters most in a bathroom. Water is not absorbed into the body of the tile.

Hardness. Hard wearing and resistant to scratching and chipping.

Maintenance. No sealing required. Resistant to staining. Ordinary cleaning is enough.

Appearance. Available in almost any look, including convincing stone and timber reproductions. Through-body porcelain carries the colour right through, so a chip is far less visible than on a glazed tile with a different coloured body.

Where it suits. Floors, shower floors, walls, wet areas generally. For most Sydney bathrooms this is the sensible default throughout.

Downsides. More expensive than ceramic, and harder to cut, which shows up as labour on a job with many cuts.

Ceramic

Softer, more porous, fired at lower temperature.

Water absorption is higher. Not a problem on a wall above a splashback. More of one on a floor or in constant contact with water.

Hardness. Softer than porcelain and easier to chip.

Maintenance. Glazed ceramic resists staining on the surface. A chip exposes the body underneath, which is usually a different colour and obvious.

Where it suits. Walls, especially outside the shower. It is a perfectly good wall tile and the saving over porcelain is real.

Downsides. Generally not the best choice for bathroom floors.

Natural stone

Marble, travertine, limestone, slate and others. A genuinely different proposition.

Porosity. Stone is porous, and varies considerably by type. It needs sealing when installed and resealing periodically, on a schedule that depends on the stone and the use.

Chemical sensitivity. Many stones, particularly marble and limestone, are calcium based and react to acids. Common bathroom cleaners, and some cosmetics, can etch the surface leaving a dull mark that is not dirt and does not clean off.

Variation. Every piece is different, which is the appeal. It also means colour and veining vary across a delivery, so tiles need laying out and selected before fixing rather than taken straight from the box.

Dimensional consistency. Stone varies in size and thickness more than a manufactured tile, which makes it slower to lay and often requires a wider grout joint.

Where it suits. Households that want stone and accept the maintenance. It is beautiful in a way porcelain reproductions do not quite match.

Downsides. Cost, both in material and labour. Ongoing maintenance. Sensitivity to the cleaning products most people already own.

Choosing honestly

The question worth asking is not which is best, but which suits how the bathroom will actually be used.

A busy family bathroom wants porcelain. Low maintenance, hard wearing, and forgiving of whatever cleaning product is in the cupboard.

A main bathroom or ensuite where you want stone and will look after it can absolutely have stone. Just go in knowing about sealing and acidic cleaners.

A budget-conscious renovation can reasonably use porcelain on the floor and shower, and good ceramic on the walls outside the wet area. That is a sensible allocation of spend rather than a compromise.

The slip resistance point

Whatever material, a bathroom floor tile needs an appropriate slip rating. This is independent of material. Polished stone and polished porcelain can both be slippery wet.

Cost order

Ceramic is generally cheapest, porcelain sits in the middle with a wide range, and natural stone is generally the most expensive both to buy and to lay.
