When renovating your bathroom, choosing the right tiles determines whether you get a stunning sanctuary or a maintenance headache. As tile experts, we know the bathroom environment—with its constant moisture and temperature shifts—demands materials that perform.

Ceramic tiles are the smart choice for homeowners and professionals alike. They offer water resistance, durability, and immense versatility. In this guide, we break down the technical differences between ceramic and porcelain, installation best practices, and how to maintain them for decades.

In this guide:

Key points

  • Porcelain Power: Porcelain ceramic tiles (fired at higher temperatures) offer superior moisture protection (<0.5% absorption) for wet areas.
  • Finish Matters: Matt and textured finishes provide essential slip resistance for floors; glossy tiles are ideal for walls.
  • Installation Criticals: Waterproofing (tanking) behind tiles in wet areas is non-negotiable for longevity.
  • Maintenance: Regular sealing of grout lines prevents moisture damage and keeps your bathroom hygienic.

Why ceramic tiles are the smart choice for bathrooms

The secret to ceramic's success lies in the firing process. Fired at over 1000°C, clay becomes dense and naturally water-resistant.

Cost-Effectiveness: While natural stone can cost £40-150 per square metre, ceramic and porcelain options typically cost less, leaving budget for essential waterproofing.
Thermal Stability: Unlike wood, ceramic handles bathroom temperature fluctuations perfectly, making it ideal for underfloor heating.

Shower Areas & Wet Rooms

This is the most demanding zone. Porcelain tiles with a PEI rating of 3-4 are essential here.
Safety First: Look for tiles with an R10 slip rating minimum. R11-R12 is safer for elderly residents.
Design Tip: Use large format tiles (30x60cm+) to minimise grout lines, reducing areas where mould can grow.

Bathroom Floors

Matt finishes or textured tiles provide superior grip compared to gloss. If you are using large format tiles, ensure your subfloor is perfectly level to prevent "lippage" (uneven edges).

Bathroom Walls

Here you have more freedom. Standard ceramic works well. High-gloss finishes reflect light, making small spaces feel larger. Consider subway tiles or creating a feature wall with patterned tiles.

Size, layout & design considerations

300x600mm: The versatile standard. Vertical installation emphasises height; horizontal makes rooms feel wider.
Mosaics: Perfect for curved surfaces (like shower seats) and sloping wet room floors as the extra grout lines add grip.
Layouts:
Brick Bond: Classic and hides minor wall imperfections.
Herringbone: Adds sophistication but requires more cuts and waste (plan for 15% extra).

Installation best practices

1. Waterproofing (Tanking)

This is critical. Tiles are water-resistant, but grout is porous. You must apply a liquid tanking membrane behind tiles in wet areas to prevent structural rot.

2. Adhesive Selection

Use flexible, waterproof adhesives specifically for bathrooms. Standard wall paste often fails with heavier porcelain tiles or in wet environments.

3. Grouting

Epoxy grout is superior for moisture resistance but harder to apply. Polymer-modified cement grout is a good middle ground. Ensure grout lines are at least 2mm wide to prevent cracking.

Maintenance and longevity tips

  • Daily: Use a squeegee on shower tiles to prevent soap scum build-up.
  • Cleaning: Use pH-neutral cleaners. Acidic cleaners (vinegar/lemon) can degrade grout over time.
  • Sealing: Reseal cement-based grout lines every 12-18 months to prevent staining and water absorption.
  • Ventilation: Always run the exhaust fan during and after showers to reduce humidity and prevent mould.

Common mistakes to avoid

  • Skipping Waterproofing: Relying on tiles alone to stop water is the #1 cause of bathroom leaks.
  • Wrong Adhesive: Using standard tub paste for porcelain tiles (it won't dry properly) or floors (it's too weak).
  • Bad Prep: Tiling over uneven or dusty surfaces leads to loose tiles.
  • Rigid Grouting: Failing to use silicone (flexible sealant) in corners and where walls meet floors causes cracks due to natural movement.
