300x300 mm Tiles (1x1 ft): Uses, Coverage and Tips

300x300 mm is the small square size most people know as the 1x1 ft tile. It has been around for decades and is still the usual choice for bathroom floors, balconies and other wet or outdoor spots where grip and drainage matter more than a big, joint-free look.

Size in feet and where it is used

A 300 mm tile is just under 1 ft (1 ft is 304.8 mm), so it is sold and spoken of as 1x1 ft. You will mostly see it on:

• Bathroom floors, especially the shower area
• Balcony and utility floors
• Terrace floors, including many cool roof tiles
• Garden paths, sit-outs and small service areas

Coverage per tile

The working: 300 x 300 = 90,000 sq mm, divided by 92,903 sq mm per sq ft, gives 0.97 sq ft. Add 5 to 10 percent for cuts and breakage, more if the room has many corners. Our tile calculator does this for you.

Box quantities vary by manufacturer and thickness, so check the box label or ask us for the design you choose rather than going by a fixed number.

Tile types you usually find in this size

• Anti-skid tiles with a textured matt surface for bathroom and balcony floors
• Ceramic tiles in plain and printed designs
• Terracotta-look and stone-look outdoor tiles
• Heat-reflective terrace tiles

Glossy finishes are less common in this size because it is mostly used on wet floors.

Laying and handling tips

• Small tiles follow a slope easily, which is why tilers like them in shower areas where water must run to the drain.
• More grout lines means more grip but also more cleaning. A grey or darker grout hides dirt better on balconies.
• Use spacers so the lines stay straight across the room. See our grout and spacers guide.
• Lay out a few tiles dry before fixing to check the pattern and shade.
