How Many Tiles Do I Need Per Square Metre?
The number of tiles per m² depends entirely on tile size. Here’s a quick reference for the most common UK tile sizes, including coverage and approximate 2026 prices.
| Tile Size | Tiles per m² | Best For | Price Range (2026) |
|---|---|---|---|
| 300 × 300 mm | 11.1 | Small bathroom floors, splashbacks | £12–£30 per m² |
| 450 × 450 mm | 4.9 | Kitchens, utility rooms | £15–£40 per m² |

How to Use This Tile Calculator
Step 1: Choose Your Project Type
Floor: Enter the room length and width. The calculator works out the total floor area. Wall: Enter the wall width and height. Shower: Enter the enclosure width, depth and height — the calculator measures three walls automatically. Custom: Enter a pre-measured area in m² if you’ve already done the maths.
Step 2: Select Your Tile Size
Choose from the most common UK tile sizes or enter a custom size. The calculator adjusts tile count, grout and adhesive quantities automatically. For walls, 600 × 300 mm is the UK’s most popular choice. For floors, 600 × 600 mm is standard.
Step 3: Choose Your Layout Pattern
A straight or brick-bond layout wastes around 10% of tiles on cuts. Diagonal and herringbone patterns waste around 15% because every edge tile needs an angled cut. The calculator adds the right wastage percentage automatically.
Step 4: Check Your Grout Joint Width
Standard UK practice is a 3 mm grout joint. For a sleek modern look, 2 mm joints work well with rectified tiles. For natural stone or rustic tiles, 5 mm joints are typical. Wider joints use more grout.

Types of Tiles for UK Homes
Ceramic Tiles
The most affordable option, made from kiln-fired clay with a glazed surface. Suitable for walls and light-traffic floors. Not recommended for outdoor use or high-moisture areas without proper sealing. Price: £12–£30 per m².
Porcelain Tiles
Denser and harder than ceramic, fired at higher temperatures. Suitable for walls, floors, and wet areas including showers and kitchens. Frost-resistant versions work outdoors. The UK’s most popular choice for bathroom and kitchen floors. Price: £20–£55 per m².
Natural Stone (Marble, Travertine, Slate)
Premium natural materials that require sealing and more maintenance. Each tile is unique, which is part of the appeal. Travertine is popular for bathroom floors; slate works well in hallways and kitchens. Price: £40–£100+ per m².
Mosaic Tiles
Small tiles (typically 25–50 mm) mounted on mesh sheets for easy installation. Popular for shower niches, splashbacks and feature strips. Labour-intensive to cut and fit around obstacles. Price: £40–£100 per m².
Large-Format Tiles (900 mm+)
Create a clean, modern look with minimal grout lines. Require a perfectly level substrate and experienced installation. Increasingly popular in UK new builds and renovations. Usually need two people to handle during installation. Price: £25–£80 per m².
5 Common Tiling Mistakes (and How to Avoid Them)
1. Not Ordering Enough Tiles
The number one tiling mistake. Always add at least 10% for a straight layout and 15% for diagonal patterns. Keep spare tiles for future repairs — your tile batch may be discontinued by the time you need a replacement.
2. Skipping the Waterproofing
Tiles alone are not waterproof. In wet areas (showers, bath surrounds), you must apply a tanking membrane or liquid waterproofing before tiling. Without it, moisture seeps behind tiles and causes mould, loose tiles and structural damage.
3. Using the Wrong Adhesive
Standard adhesive works for small ceramic wall tiles, but porcelain and large-format tiles need flexible adhesive. Wet areas need a waterproof or water-resistant adhesive. Using the wrong type is the most common cause of tiles falling off walls within the first year.
4. Not Levelling the Substrate
Tiles amplify any bumps or dips in the surface underneath. Use self-levelling compound on floors and skim-coat or plasterboard walls before tiling. For large-format tiles (600 mm+), the substrate must be flat to within 3 mm over a 2 m span.
5. Starting From the Wrong Point
Never start tiling from a corner or edge — walls and floors are rarely square. Find the centre of the wall or floor, dry-lay tiles from the centre outward to check the layout, then adjust so you avoid narrow sliver cuts at the edges. Slivers look bad and are hard to cut cleanly.
