Ceramic Tile (Glazed Fired Clay Tile)
Sets out how ordinary ceramic tile differs from porcelain in body, firing and behaviour, so that the two are not treated as interchangeable when a room and its assembly are being decided.
Educational reference entry. Suitability depends on the complete assembly, substrate, exposure, installation method, manufacturer documentation, local requirements and qualified professional review.
Overview
What ceramic tile is
Ceramic tile is made from clay bodies pressed or extruded into shape, dried and then fired, usually at a lower temperature than porcelain. The fired body stays more open and more absorbent than a porcelain one, and it is normally finished with a glaze that provides the colour, the pattern and the working surface.
That difference in body is the practical distinction between the two. A more open body takes up more water, which is why ceramic is generally discussed for internal walls and lighter-duty internal floors, while porcelain is the family usually considered where wetting, freezing or heavy traffic are involved. Because the glaze carries all the colour, a chip exposes the paler body underneath quite plainly.
The softer body brings its own advantages. Ceramic is easier to cut and drill on site, lighter to handle on a wall, and produced in a very wide range of small formats, shaped trims and decorative glazed faces that are harder to find in denser porcelain bodies.
Terminology
Common names and aliases
These names describe the same thing. The library keeps one entry per material so that an acronym, a trade name or a regional spelling never becomes a second, thinner page.
- Ceramic tiles
- Glazed ceramic tile
- Wall tile
- Glazed wall tile
Applications
Common applications
Where this material is typically encountered. A typical application is not a statement that it suits your project.
- Bathroom and cloakroom wall finishes above baths and basins and behind sanitaryware.
- Kitchen splashbacks, including the small brick-format tiles used in a great many kitchens.
- Decorative feature panels and patterned wall areas in halls, utility rooms and porches.
- Lighter-duty internal floors in rooms where the product is documented by its maker for floor use.
- Trim, edge and coving pieces that finish the perimeter of a tiled area neatly.
Consideration
Where it is commonly considered
- Where a wall finish is wanted that can be wiped down around cooking, washing and grooming.
- Where a specific colour, glaze character or handmade look is only available in a ceramic range.
- Where many small cuts, notches and drilled holes are expected around fittings and services.
- Where the weight of a wall covering matters and a lighter tile is easier to bed and hold.
Professional review
Where additional professional review is especially important
These are the situations where the answer depends on the specific building, and where a qualified professional should be involved before anything is decided.
- On external walls, paving and terraces exposed to weather and to freezing conditions.
- On floors that take heavy traffic, abrasive grit or wheeled loads day after day.
- In showers and other continuously wetted areas, where the assembly behind the tile governs the outcome.
- Where a chipped edge showing a pale body would be unacceptable in a prominent position.
- Over substrates that flex, that are still drying out, or that have not been assessed.
Properties
Key properties to discuss
Qualitative topics worth raising. Measured values, classes and grades come from the manufacturer's technical documentation for the specific product, not from a reference page.
- Moisture behaviour
- Ceramic bodies are more open than porcelain and take up more moisture, which is the main reason the two are considered for different locations. What a particular tile may be used for is stated by its maker rather than by the material name.
- Surface wear
- The glaze is the working surface. Once it has been worn through or chipped, the paler body shows, and there is no way to restore it locally, so the tile is replaced rather than repaired.
- Appearance
- Glazes carry gloss, colour depth and small variations that are difficult to reproduce in denser bodies, which is why hand-finished, crackle and reactive glaze looks are so often ceramic rather than porcelain.
- Installation dependency
- The softer body cuts and drills more easily than porcelain, which matters on a wall full of pipework, switches and fixings, and it reduces the amount of specialist cutting equipment needed.
- Substrate dependency
- Wall tiling depends on its background. Plaster, boards and masonry all behave differently, and old, painted or friable surfaces need assessment before anything is bedded onto them.
- Repairability
- Individual tiles can often be cut out and replaced, but matching a glaze years later is uncertain, so keeping spares from the original batch is the practical safeguard against a mismatch.
Exposure
Exposure and environmental conditions
- Is this surface going to be splashed occasionally, or wetted more or less continuously?
- Does the wall sit behind a heat source such as a hob or a stove, and has that been considered?
- Will the area ever be exposed to frost, for example in an unheated outbuilding or porch?
- How much steam does this room generate, and how is that moisture actually removed?
Assembly
Substrate and system dependencies
What this material sits on, is fixed to or depends on. This is usually where performance is won or lost.
- Plastered walls have to be sound, dry and free of loose paint or old adhesive before tiling.
- Boarded walls depend on the board type, on its fixings, and on how the board joints are treated.
- Wet-area backgrounds normally involve a separate strategy for managing water that sits behind the tiling.
- Corners, internal angles and junctions with baths and trays are usually formed in sealant rather than rigid grout.
- A heavy area of wall tiling depends on the background's ability to carry it, which is a judgement for a professional.
Appearance
Appearance and finish considerations
- Gloss glazes show unevenness in the wall behind them far more than matt ones under raking light.
- Handmade and hand-glazed tiles vary in size and face, and the layout has to allow for that variation.
- Joint width and colour dominate the look of small-format tiling such as a brick-bond wall.
- Trim and edge pieces determine how neatly a tiled area stops, and they are easy to forget when ordering.
- Batch shade variation applies to ceramic just as it does to porcelain, so batches are worth confirming.
Durability
Durability questions
Questions to raise rather than a service life to expect. No material has a universal lifespan — it depends on the assembly, the exposure and the upkeep.
- Will anything in this room strike or knock the tiled surface on a regular basis?
- How visible would a chipped edge showing the pale body be in this particular position?
- Is the glaze on this range described by its maker as intended for floors as well as walls?
- How are the external corners protected, and what happens if one of them is knocked?
Upkeep
Maintenance and repair considerations
- What does the maker advise for cleaning this particular glaze over the years?
- Are spare tiles from the same batch being retained somewhere they will not be damaged?
- How will discoloured joints be dealt with in a few years' time, and by whom?
- Can the sealant lines be renewed without disturbing the tiling around them?
Installation
Installation dependencies
What the installation depends on — not how to do it. Method belongs to the manufacturer's instructions and the trades carrying out the work.
- Setting out determines whether the cut tiles land in prominent positions or discreet ones.
- Fixings taken through tiles for accessories need care if the glaze is not to crack.
- Bedding and jointing products have to suit the tile, the background and the room, which is the installer's decision.
- Where the tiling stops part-way up a wall, the edge detail has to be decided before work starts.
Documentation
Documentation to request
Ask for these in writing, for the specific product being proposed, and keep them with the project record.
- The maker's data sheet for the specific range, including the locations it is intended for.
- Confirmation of whether the range includes matching trims and pieces intended for floors.
- Batch information covering the full quantity of tiles supplied to the job.
- The maker's cleaning and care guidance for the chosen glaze and colour.
Conversations
Questions for qualified professionals
Bring these to the relevant qualified professional, manufacturer or authority. Requirements vary by project and location.
- Is ceramic the right family here, or does the exposure in this room point towards porcelain?
- Is this background sound, dry and stable enough to take tiling at all?
- How will the junctions with the bath, the shower tray or the worktop be sealed?
- Where will the cut tiles fall with the setting out you are proposing?
- Does this range include the trim pieces needed to finish the edges we actually have?
- What preparation is needed if this wall has been tiled once before?
Blind spots
Commonly overlooked points
- The joints and sealant lines, rather than the tiles, usually determine how a tiled bathroom ages.
- Ceramic and porcelain sold under one visual range are often different products with different bodies.
- Tiling over old tiles changes the wall build-up and may affect how fittings and fixtures sit.
- Small-format tiling takes considerably longer to lay than the same area in large tiles.
What this page does not do
- This entry does not state that ceramic tile is suitable for a floor, a shower or any external position, because that depends on the specific product and the whole assembly.
- No absorption or wear figures and no slip characteristic are given here, and grout and sealant are not treated as a layer that keeps water out of an assembly.
- Build Design Hub is a publisher and does not test, approve or endorse any tile or installer.
