The size of your bathroom floor tiles can be quite subjective. From 4-inch to 12-inch - it's ideal that you choose a size that may not look very small or busy and at the same time, is easy to cut and lay. Generally, the 12-inch by 12-inch or 24-inch by 24-inch works the best!
For the best tile for bathroom floors, consider tile sizes between 1 inch and 12 inches or even bigger. Small mosaic tiles, usually 1- or 2-inch squares, are very popular for bathroom floors, as are other square tiles.
It's important to distinguish between what we mean by small, medium, large, or extra-large bathroom floor tiles. Small bathroom floor tiles: Anything up to 200x200mm. Medium bathroom floor tiles: Anything between 200x200mm to 600x600mm. Large bathroom floor tiles: Anything from 600x600mm to 900x450mm.
For a small bathroom, large tiles are generally recommended to create a more open and spacious feel, especially on the floor. However, using small tiles can work well for accents or in shower areas. Consider a mix of both if you want to incorporate design elements.
Choose Large-Format Tiles
Large format tiles (tiles that are larger than 60cm x 60cm) will make your bathroom feel bigger than it really is. Firstly, there will be fewer grout lines, so your walls & floors will look more seamless & less cluttered & restrictive. Secondly, the scale will make your space feel larger.
One of the primary drawbacks of large format tiles is that they require skilled professionals for installation. Because these tiles are larger and heavier than standard tiles, they can be difficult to handle and install. This means that installation costs can be higher than with smaller tiles.
It is important to note that the larger the surface area to be covered, the larger the tile size should be in relation to this. Using larger tiles will actually reduce the number of joints, and therefore improve the aesthetic appearance of your preferred style.
Use Large-Format Tile
Large-format tile requires fewer grout lines, which can make a small space feel larger. The Livingstone Melange tile used for the floor and half-wall of this bathroom, designed by Nikki Chu, creates the illusion of an expansive space.
Larger Tiles Make Small Rooms Appear Bigger
Because grout lines are thinner and fewer as part of the layout, smaller rooms appear bigger when using larger tiles. Large-format tiles make floors look more streamlined – therefore, creating the illusion of more space.
When tiles are laid horizontally, and to the ceiling, the bathroom looks wider and more spacious. Compare this to a vertical laid tile, which tends to make the ceilings look taller but the space tighter.
It is a matter of personal preference. Traditionally, smaller wall tiles are combined with larger floor tiles to add contrast and texture. But, larger wall tiles look great in smaller bathrooms as they create the illusion of space. Want to explore your tile options?

Fewer Grout Lines, More Open Space
Let's bust the myth that small bathrooms need small tiles. Here's the surprising truth: large format tiles or slab porcelain tiles can be your best friend in creating the illusion of a more open and spacious bathroom.
Find tilers and worktop professionals in your area. A chevron or herringbone pattern can make a room appear bigger, as the shapes move the eye along the surfaces. In this bathroom, the tiles lead the way along the floor and up the wall to make the space feel longer and taller.
A 16″ or 18″ tile will generally give a room a larger feeling than a 12″ tile. One of the main reasons for this is the lack of grout lines. The less grout lines, the less busy your floor is and the more expansive it appears. This expansiveness naturally will make your room appear larger.
The Costs. Large format tile can be a cost-effective alternative to natural stone slabs if you're looking to produce a similar organic look. However, depending on the size of tile needed, large format tiles may cost more than regular smaller tiles.
Tiles that exceed 4”x4” are usually the best for bathroom walls. If the tiles are longer than they are high, they will be a good fit for bathroom walls featuring similar dimensions. Tiles measuring a 12” height and 24” length work well for homeowners who love the look of larger tiles.
The golden rule when installing tiles is install on a concrete floor where possible and always ensure it's level by applying a levelling compound beforehand – watch this video to find out exactly how.
The large size makes them quicker to lay and creates a uniform surface, making the room look big, bright, and minimalistic. In contrast, large tiles are not ideal for those hoping to mix shape, color, or pattern. If you want to create an intricate design, small tiles are your best option.
Since ceramic tiles don't absorb moisture, the chances of mold and bacteria build-up are also low on them. Generally, high-gloss tiles are the best bathroom wall tile choice, as you can wipe off water and soap stains. However, you can use rocker and matt finish tiles in dry areas.
