Install ceramic tiles.

Whether you are updating a small splashback or tiling an entire wet room, understanding the process ensures you get a result that looks professional and stands the test of time. A well-tiled room not only improves daily use but can significantly boost your property's market value.

What Does the Work Involve?

• Site Assessment: Measuring the area and checking the substrate (walls or floor) for level, moisture, and structural integrity.
• Surface Preparation: Removing old tiles, levelling floors with screed, or installing waterproof "tanking" systems in shower areas.
• Setting Out: Planning the layout to ensure symmetrical cuts and avoiding "slivers" (very thin tile strips) at the edges.
• Adhesive Application: Spreading the correct grade of adhesive using a notched trowel to ensure 100% coverage.
• Tile Installation: Fixing tiles with spacers to maintain consistent grout lines and using a spirit level to ensure a flat finish.
• Cutting: Using manual rail cutters or electric wet saws to fit tiles around sockets, pipes, and corners.
• Grouting: Filling the joints with grout, followed by a thorough cleaning to remove "haze" from the tile surface.
• Sealing: Applying silicone sealant to internal corners and junctions to allow for movement and prevent leaks.

Typical Costs

Prices for ceramic tiling vary based on your location in the UK and the complexity of the pattern (e.g., Herringbone costs more than a standard Brick Bond). Most tilers quote per square metre for larger areas, but will charge a day rate for smaller, fiddly jobs.

Expect to pay a premium for "large format" tiles or intricate mosaics, as these require more time and specialised equipment to install correctly. Always check if your quote includes the removal and disposal of old tiles, as skip hire or waste bags can add £100–£200 to the total.

How Long Does It Take?

• Kitchen Splashback: 1 day (including grouting).
• Standard Bathroom Floor: 1 to 2 days (allowing for adhesive to cure before grouting).
• Full Bathroom Walls & Floor: 3 to 5 days depending on the amount of cutting required.
• Large Kitchen/Diner Floor (30m²): 4 to 6 days including preparation and sealing.

DIY or Professional?

While a confident DIYer can tackle a small, flat splashback, larger projects usually require a professional. Ceramic tiles are brittle; incorrect cutting leads to high wastage, and poor "setting out" can leave your room looking crooked. Professionals also ensure "tanking" is done correctly in bathrooms, which is vital to prevent long-term structural rot and insurance-voiding leaks.

Pro Tip: If you are installing underfloor heating, always hire a professional tiler. They will use flexible adhesives and grouts that won't crack when the floor expands and contracts with the heat.

Choosing the Right Tradesperson

• Check Qualifications: Look for NVQ Level 2 or 3 in Wall and Floor Tiling, or membership in The Tile Association (TTA).
• View a Portfolio: Ask for photos of their "setting out" around windows and corners; this is where true skill is shown.
• Verify Insurance: Ensure they have Public Liability insurance to cover any accidental damage to your plumbing or property.
• Ask these questions:
  • Do you include "tanking" in your quote for shower areas?
  • Will you be using a decoupling membrane for the floor?
  • How do you handle waste disposal?
  • Can you provide references from jobs completed in the last six months?

UK Regulations

• BS 5385: This is the British Standard for the design and installation of wall and floor tiling. A professional should always work to these guidelines.
• Part P (Building Regs): If tiling involves moving sockets or working near bathroom electrics, a qualified electrician may need to sign off that specific work.
• Document M: Covers accessibility; important if you are installing a wet room or level-access shower for elderly or disabled residents.

Common Problems

• Lippage: This occurs when the edges of tiles are not flush with each other, creating a trip hazard and an ugly finish. It is usually caused by rushing or an uneven substrate.
• Dot and Dab: A "cowboy" technique where adhesive is only put on the corners of the tile. This leaves hollow voids that crack easily and allow water to collect.
• Grout Cracking: Often caused by using the wrong adhesive for the substrate or failing to allow for natural movement in the building.
• Poor Drainage: In wet rooms, if the tiles aren't pitched correctly toward the drain, water will pool and cause mould or leaks.
