🧱 What Are Porcelain and Ceramic Tiles?
Understanding the basic composition helps explain the performance differences.
Ceramic Tiles
Ceramic tiles are made from natural clay, sand, and water, shaped and then fired in a kiln at temperatures around 1,000°C. They’re typically finished with a glaze that provides colour, pattern, and a protective layer. The body (bisque) beneath the glaze is porous.
- Body: Red or white clay, relatively soft and porous
- Surface: Glazed – colour and pattern are on the surface only
- If chipped: The underlying clay colour shows through
- Best for: Walls and low-traffic floor areas
Porcelain Tiles
Porcelain tiles are a specific type of ceramic tile made from finer, denser clay and fired at higher temperatures (1,200-1,400°C). This creates an extremely dense, hard tile with very low porosity. Porcelain can be through-bodied (colour throughout) or glazed.
- Body: Dense, compacted clay – extremely hard
- Surface: Can be glazed or unglazed (through-body)
- If chipped: Through-body porcelain shows the same colour throughout
- Best for: Floors, wet areas, high-traffic zones, outdoors

🛡️ Durability & PEI Ratings
The PEI (Porcelain Enamel Institute) rating measures a tile’s resistance to abrasion – crucial for floor tiles.
| PEI Rating | Application | Ceramic | Porcelain |
|---|---|---|---|
| PEI 1 | Walls only – no foot traffic | ✅ Common | ❌ Rare |
| PEI 2 | Light traffic – bathrooms, bedrooms | ✅ Common | ✅ Available |
| PEI 3 | Moderate traffic – all residential areas | ✅ Common | ✅ Common |
| PEI 4 | High traffic – kitchens, hallways, light commercial | ⚠️ Limited | ✅ Common |
| PEI 5 | Heavy traffic – commercial, public spaces | ❌ Rare | ✅ Available |
Impact Resistance
Porcelain’s density makes it significantly more resistant to impact and chipping. Ceramic tiles are more likely to crack if something heavy is dropped on them.
Scratch Resistance
Both can be scratch-resistant, but through-body porcelain has colour throughout – if scratched, the colour remains consistent. Glazed ceramic scratches may reveal the underlying clay.
💧 Water Resistance & Porosity
This is the most critical difference between porcelain and ceramic.
Water Absorption Standards (SANS 10107)
- Porcelain: <0.5% absorption – classified as impervious
- Ceramic: 3-7%+ absorption – classified as semi-vitreous to non-vitreous
Implications for Different Areas
- Bathroom floors: Porcelain essential – constant water exposure
- Shower walls: Porcelain recommended; ceramic possible with good waterproofing
- Kitchen floors: Porcelain ideal for spills; ceramic can work if spills wiped promptly
- Outdoor areas: Porcelain essential – ceramic will absorb moisture and crack in frost
- Pool surrounds: Porcelain only – must withstand constant moisture
For bathroom tiling and kitchen tiling, porcelain is the safer choice for floors and wet areas.
Pro Tip: “High-traffic areas or spaces exposed to moisture, such as kitchens and bathrooms, benefit from the superior durability and water resistance of porcelain tiles.” – CTM Tile Selection Guide
🛠️ Installation Differences
The installation requirements differ significantly between porcelain and ceramic.
Cutting
- Ceramic: Can be cut with manual tile cutters or wet saws. DIY-friendly.
- Porcelain: Requires diamond-blade wet saws. Harder to cut cleanly – more skill required.
Joint Widths – TAL Specifications
TAL’s technical guidelines specify different minimum joint widths:
- Ceramic floor tiles: Minimum joint width 5mm
- Porcelain tiles (including rectified): Minimum joint width 3mm
- Large format porcelain: Requires back buttering for 95% coverage
Substrate Requirements
Porcelain tiles, especially large format, require perfectly level substrates. Any imperfection translates to lippage. Ceramic is more forgiving.
DIY vs Professional
- Ceramic: Suitable for confident DIYers for walls and small floors.
- Porcelain: Professional installation strongly recommended, especially for floors and large formats.
For professional floor tiling and commercial tiling, experienced tilers ensure proper installation.

🗺️ Regional Preferences – South Africa
Different regions have different climate challenges that influence tile choice.
| Region | Climate Challenge | Tile Preference | Rationale |
|---|---|---|---|
| Gauteng | Temperature swings, dry winters, dust | Porcelain, wood-look porcelain | Temperature stability, durability, easy cleaning |
| Cape Town | Humidity, rainy winters, sea air | Porcelain, slip-resistant porcelain | Moisture resistance, coastal performance, slip safety |
| Durban | High humidity, coastal salt | Porcelain | Humidity resistance, low porosity, mould-resistant grout |
According to Tiletoria’s regional guide: “In Cape Town’s coastal climate, porcelain tiles with low water absorption are preferred. The humidity and rain require tiles that won’t absorb moisture or support mould growth.”
For homes in Johannesburg, Cape Town, or Durban, local tilers understand these regional requirements.

❓ Frequently Asked Questions – Porcelain vs Ceramic
What’s the main difference between porcelain and ceramic tiles?
Porcelain is denser, fired at higher temperatures, and has water absorption below 0.5%. Ceramic is less dense, with 3-7%+ absorption. This makes porcelain more durable and water-resistant.
Which is cheaper – porcelain or ceramic?
Ceramic is significantly cheaper – R80-250/m² vs R200-500/m² for porcelain. Installed, ceramic costs R230-500/m², porcelain R380-800/m². Porcelain’s durability justifies the premium for floors and wet areas.
Can I use ceramic tiles in a shower?
On shower walls, yes – with proper waterproofing. For shower floors, porcelain is essential due to constant water exposure. Ceramic’s higher absorption can lead to moisture issues.
Which tile is more durable for floors?
Porcelain is significantly more durable. With PEI ratings up to 5, it withstands heavy traffic, impacts, and abrasion. Ceramic (PEI 1-3) is suitable for light to moderate traffic only.
Do porcelain tiles need sealing?
Glazed porcelain doesn’t need sealing – the glaze is impervious. Unglazed or through-body porcelain may benefit from sealing to prevent stains. Grout always needs sealing regardless of tile type.
Can porcelain tiles be used outdoors?
Yes, if specified for outdoor use. Porcelain’s low absorption makes it frost-resistant. Choose tiles with appropriate slip rating (R11+) for wet outdoor areas like patios and pool surrounds.
Which is easier to install – porcelain or ceramic?
Ceramic is much easier to cut and install – DIY-friendly with manual cutters. Porcelain requires diamond blades and wet saws, and benefits from professional installation, especially for large formats.
What is rectified porcelain?
Rectified porcelain tiles are precisely cut after firing, creating perfectly uniform dimensions and sharp 90° edges. This allows for very narrow grout joints (3mm) and a seamless look.
Which is better for underfloor heating?
Both work well – tile conducts heat efficiently. Porcelain’s density means it heats up slightly slower but retains heat longer. Ensure flexible adhesive is used with underfloor heating.
How do I choose between porcelain and ceramic?
Consider: location (wet/dry), traffic (light/heavy), budget, and DIY vs professional. Use our decision guide above or consult professional tilers for advice.
✅ Final Thoughts – Making the Right Choice
