    Porcelain vs CeramicWhich Should You Choose? A DW Tiles Comparison Guide

    Cross-section comparison of porcelain tile (dense, uniform) vs ceramic tile (coarser clay body)
    ( Quick Answer )

    Porcelain tiles are denser, harder, and absorb less water than ceramic tiles, making them the better choice for floors, wet areas, outdoor spaces, and high-traffic applications. Ceramic tiles cost less and suit internal walls and low-traffic floors. For most Australian homes and commercial projects, porcelain is the recommended tile type.

    ( The Decision )
    • Water Absorption
    • Hardness
    • Cost & Application

    Choosing between porcelain and ceramic tiles is one of the most common decisions builders, tilers, and homeowners face. Both are fired clay tiles, but they differ significantly in density, water resistance, and durability, and those differences dictate where each tile should and should not be used.

    This guide explains the key differences, with technical data relevant to Australian standards and construction requirements.

    ( The Difference )

    What Is the
    Difference?

    Both tile types begin with clay and water, but porcelain uses a finer, denser clay body fired at higher temperatures (1,200 to 1,400°C vs 900 to 1,100°C for ceramic). The result is a tile with fundamentally different physical properties.

    ( For Floors )

    Better for
    Floors?

    Yes, for most floor applications, porcelain outperforms ceramic. Here is why:

    • AWater resistance: porcelain's below 0.5% absorption is essential for bathroom floors, laundries, and outdoor areas under the NCC
    • BWear resistance: PEI IV to V rated porcelain handles foot traffic, trolleys, and furniture without surface degradation
    • CSlip resistance: AS 4586-compliant porcelain is available in P3+ ratings for wet area compliance
    • DLongevity: the denser tile body resists chipping at corners and edges in high-traffic areas

    Ceramic is suitable for internal dry floors in low-traffic rooms (for example, a bedroom or study) where budget is a primary consideration.

    ( Bathroom Walls )

    Better for
    Bathroom Walls?

    Ceramic tiles remain popular for bathroom walls. Because walls are not load-bearing and do not face foot traffic or standing water (compared to floors), ceramic's lower water absorption (below 3%) is acceptable for splashback and shower walls above the waterline.

    However, for shower floors and wet-area floors where the NCC requires impervious ratings, porcelain or a vitrified tile with below 0.5% absorption is required.

    Recommendation: use porcelain on floors and wet areas, ceramic on dry bathroom walls if budget is a constraint.

    04
    ( Outdoors )

    Ceramic
    Outdoors?

    No. Standard ceramic tiles are not suitable for Australian outdoor applications for two reasons:

    • AWater absorption above 0.5% means moisture penetrates the tile body, causing cracking when temperature fluctuates
    • BCeramic lacks the AS 4586 slip ratings required for outdoor areas under the NCC

    For outdoor use, including pool surrounds, alfresco areas, driveways, and commercial exteriors, select porcelain with a minimum P3 slip rating and confirmed impervious rating.

    ( Questions )

    Frequently
    Asked

    Is porcelain more expensive than ceramic?
    Yes, typically. Trade pricing for porcelain tiles from DW Tiles starts from approximately $40 per m² compared to $15 to $25 per m² for standard ceramic. However, porcelain's longer lifespan and reduced replacement cost make it more cost-effective over a building's lifecycle.
    Can you tell the difference between porcelain and ceramic by looking?
    Not reliably from the surface. The key indicator is the tile's cross-section: full-body porcelain shows the same colour throughout the tile body when cut. Ceramic typically shows a lighter, coarser clay body beneath the surface glaze. Check the product specification sheet for the water absorption figure (below 0.5% means porcelain).
    Is porcelain harder to cut than ceramic?
    Yes. Porcelain's higher density requires a diamond-tipped wet saw rather than a standard tile cutter. Most tilers allow for this in their labour quote. Rectified porcelain (machine-cut edges) is particularly brittle at the edge, so use the correct cutting disc and take care with large-format slabs.
    Do I need different adhesive for porcelain vs ceramic?
    Yes. Porcelain tiles require a polymer-modified adhesive that achieves full-bed coverage of at least 80% (95% in wet areas per AS 3958). The heavier tile weight and lower porosity of porcelain means standard tile adhesive may not achieve adequate bond strength.
