Square Tiles: An Australian Buying Guide
01 September 2026 · Tile Touch
Square tiles are one of the easiest shapes to plan a room around. The four equal sides give a calm, even grid, and they suit everything from a small mosaic feature to a full floor. This guide covers the sizes, materials, finishes and slip ratings that matter when you buy square tiles in Australia, with real examples from the Tile Touch range.
The short answer
For most walls, a square tile between 100 and 200 mm keeps grout lines tidy and reads well in a bathroom or kitchen. For floors, larger squares like 300 or 600 mm mean fewer joins and a flatter feel underfoot. Check the slip rating before you buy anything for a floor or wet area, and order a sample so you can see the colour in your own light.
What sizes come in a square
Square tiles run from tiny mosaics up to large floor formats. Here is how the range breaks down.
Mosaics (around 48 mm)
Mosaic squares are supplied on sheets, so a small tile face becomes easy to lay. The Clevy Square Glazed Mosaic 48x48mm in Deep Blue is a gloss porcelain mosaic that works as a splashback, a shower niche or a feature band inside a larger tiled area.
Small format (100 to 130 mm)
This is the classic wall size. Kent Nero Matt 100x100mm and Kent Grigio Matt 100x100mm are matte Italian porcelain squares that give a fine grid on walls. Ligato Pink Gloss 100x100mm brings a soft colour in a gloss finish. Stone Square Beige Tile 115x115mm is a matte Spanish porcelain with a P3 slip rating, and Nikko Spanish Square Gloss Tile 130x130mm in Soft Blue is a glazed ceramic square. Laia Clay Matt 123x123mm rounds out the group in matte porcelain.
Medium format (200 mm)
At 200 x 200 mm you get a bit more coverage per tile while keeping a defined square look. Cancun Washed Blue Square Tile 200x200mm is a ceramic in a washed blue, and Rockline Black Matt 200x200mm is a matte porcelain from Turkey with a P3 slip rating that suits floors as well as walls.
Large format (300 to 600 mm)
Bigger squares mean fewer grout lines and a more open floor. Milano Beige Matt 300x300mm is a matte porcelain with a P3 rating. For a larger floor, Sebi Almond Beige Grip 600x600mm and Sebi Dark Grey Grip 600x600mm are matte porcelain squares with a P5 slip rating, which is the grippier end of the scale.
Porcelain or ceramic?
Porcelain is denser and harder, which is why it handles floors and high-traffic areas well. Most of the squares above are porcelain, including all the Kent, Sebi, Milano, Rockline, Stone Square, Ligato, Laia and Clevy tiles. Ceramic squares like Cancun Washed Blue and Nikko Soft Blue are a good choice for walls and splashbacks, where hardwearing floor performance is not the priority. If you are tiling a floor, lean porcelain and check the slip rating.
Matte or gloss
Gloss reflects light and makes colours look deeper, which is why it reads so well on walls and splashbacks. The Clevy mosaic, Ligato Pink and Nikko Soft Blue are all gloss. Matte is calmer and hides water spotting and light scratching better, so it is a common pick for floors and larger wall areas. The Kent pair, Milano Beige, Rockline Black, Stone Square Beige, Laia Clay and both Sebi tiles are matte.
Understanding slip ratings
In Australia, floor tiles carry a P slip rating that runs from P0 to P5. A higher number means more grip underfoot when the surface is wet. As a rough guide:
- P2: suits dry indoor areas and general wall use. Kent Nero, Kent Grigio and Laia Clay carry P2.
- P3: a common choice for indoor floors and domestic bathrooms. Stone Square Beige, Milano Beige and Rockline Black carry P3.
- P5: the grippier end, useful where water pools. Sebi Almond Beige Grip and Sebi Dark Grey Grip carry P5.
Always match the rating to the room. A bathroom floor needs more grip than a bedroom feature wall, and an outdoor or step-down shower area needs more again.
Where each size suits
Small squares and mosaics shine on walls, splashbacks and shower features because the extra grout lines add texture and grip. Medium 200 mm squares are flexible, working on both walls and floors. Large 300 and 600 mm squares are best kept to floors and bigger wall runs, where their size can be appreciated and there is room to lay them flat.
How many tiles to order
Measure the area in square metres, then add extra for cuts and any future repairs. A common allowance is around 10 per cent on top of your measured area, and a little more for rooms with lots of corners or a diagonal layout. If you are unsure, our team can help you work it out from your measurements.

Colour shifts with the light in your room, so a tile can look different at home than it does on screen. Tile Touch offers samples and ships Australia-wide, and you can see the full range in person at our Waterloo showroom in Sydney.
Frequently asked questions
What is the most popular size for square wall tiles?
Small squares around 100 to 130 mm are the go-to for walls, because the grid pattern reads well at eye level. The Kent Nero and Kent Grigio 100x100mm tiles and the Nikko Soft Blue 130x130mm are examples of this size.
Can I use square tiles on a bathroom floor?
Yes, as long as the tile is rated for floor use and has a suitable slip rating. For a bathroom floor, a P3 tile like Milano Beige 300x300mm or Rockline Black 200x200mm is a common choice, while P5 options like the Sebi Grip squares give more grip where water pools.
Are square tiles harder to lay than rectangular ones?
Squares are generally straightforward because every side is the same length, which makes a standard grid layout simple to set out. Mosaics come on sheets, so a small face is easy to handle. A good tiler can also lay squares on a diagonal or with wider grout lines for a different look.
Do you deliver square tiles outside Sydney?
Yes. Tile Touch ships Australia-wide, and samples are available so you can check colour and finish before you commit. If you are in Sydney, you can also visit the Waterloo showroom to see the tiles in person.
