Top Tiling Mistakes & How To Avoid Them
Tiling is an essential part of any home décor, especially when you’re renovating kitchens or bathrooms. Tiles are a significant investment of both time and money — and because they’re designed to be hard-wearing and long-lasting, you’ll likely be living with them for many years.
Knowing the most common tiling mistakes — and how to avoid them — is key to ensuring your project runs smoothly and the finished result looks exactly as you imagined. Below, we break down the top tiling errors people make and provide clear, practical advice to help you avoid costly problems.
1. Not Ordering Samples First
Choosing tiles without seeing them in person is one of the biggest mistakes homeowners make. Without feeling the tile and viewing it in your own space, it’s impossible to be certain about colour, texture, and finish.
Lighting conditions can dramatically change how tiles appear. Kitchen tiles may look completely different under evening spotlights compared to natural daylight in the morning.
How to avoid it:
- Create a shortlist of tiles you like.
- Order samples and view them in the room at different times of day.
- Compare finishes and textures before committing to a full order.
2. Ordering Too Few Tiles
Running out of tiles mid-project causes delays and stress. Even worse, replacement tiles may come from a different batch, resulting in slight colour variations.
How to avoid it:
- Measure the area carefully (length × width).
- Add at least 10% extra for wastage and breakages.
- Allow more for complex patterns like herringbone or diagonal layouts.
- Use our Advanced Tile Calculator on product pages to order the correct quantity.
3. Not Planning Your Layout
Poor layout planning often results in awkward cuts, uneven symmetry, and tiles that don’t look balanced. Preparation at this stage saves time and frustration later.
Decide on your pattern first — brick bond, herringbone, basket weave, or vertical stack — then determine your starting point, usually the centre of the wall or floor.
How to avoid it:
- Dry-lay tiles before fixing them permanently.
- Aim for symmetry around focal points such as taps or vanity units.
- Hide cut tiles in corners or less visible areas.
4. Using the Wrong Cutting Tools
Cracked or chipped tiles are often the result of poor-quality cutting tools. Porcelain and large-format tiles, in particular, require strong and accurate cutters.
How to avoid it:
- Use tile cutters designed for your tile material.
- Measure and mark carefully before cutting.
- Investing in good tools saves time and reduces waste.
5. Skipping Tile Spacers
Tile spacers are essential — even professional tilers rely on them. Attempting to tile “by eye” almost always results in uneven grout lines.
How to avoid it:
- Use spacers or wedges for consistent joint widths.
- Select the correct spacer size for your design.
- Check alignment and level as you go.
6. Poor Surface Preparation
Tiling onto dirty, uneven, or poorly prepared surfaces leads to weak adhesion and an uneven finish.
How to avoid it:
- Remove dust, grease, screws, and debris.
- Repair uneven areas and sand smooth.
- Prime or waterproof surfaces where required.
7. Using the Wrong Tile Adhesive
Different tiles and environments require different adhesives. Wet rooms, underfloor heating, and large-format tiles all have specific needs.
How to avoid it:
- Choose adhesive suitable for your tile type and environment.
- Follow manufacturer curing and application guidance.
- Ask our experts if you’re unsure.
8. Choosing the Wrong Grout Colour
Grout colour has a huge impact on the final appearance. Dark grout can sometimes stain porous natural stone if chosen incorrectly.
How to avoid it:
- Test grout colour on sample tiles.
- Use grout colour charts for accuracy.
- Seal porous tiles where required.
9. Rushing the Grouting Process
Grouting too early or too quickly can trap moisture and leave uneven joints or grout haze.
How to avoid it:
- Wait for adhesive to fully set.
- Apply grout slowly and evenly.
- Clean haze thoroughly once cured.
10. Not Sealing Tiles Correctly
Some tiles require sealing to protect against stains and moisture. Incorrect sealing can undo all your hard work.
How to avoid it:
- Confirm whether your tile material requires sealing.
- Seal before grouting and again after cleaning.
- Use suitable sealers for kitchens and bathrooms.
Always Ask for Help If You Need It
With careful planning, the right materials, and proper preparation, DIY tiling can deliver stunning results. If you’re unsure at any stage, consulting a professional can save time and prevent expensive mistakes.
