What Should You Look for When Buying Porcelain Tiles?

When buying porcelain tiles, first match the tile’s technical performance to its intended location, then verify the finish, dimensions, shade consistency, quantity, and supplier documentation. For many porcelain tiles classified as Group BIa under relevant tile standards, water absorption is no more than 0.5%; this is a useful specification to confirm, not a substitute for checking suitability for your project. Ask for a sample, product data, and a written quotation that identifies the exact product and finish before placing an order. These steps help you compare options on more than appearance or price alone.

Key Takeaways

  • Choose tiles according to their use: floors and walls, indoor and outdoor areas, and residential or commercial settings have different performance needs.
  • Check technical documentation for water absorption, breaking strength, slip-related information, dimensions, thickness, and finish.
  • Review samples in the actual lighting and confirm shade, surface texture, and caliber before approving a bulk order.
  • Calculate the order using the installation area, the tile layout, and an agreed allowance for cutting and breakage.
  • Compare suppliers on product documentation, packaging, communication, and order terms as well as unit price.

Start With the Application

The best tile is the one that suits the space and expected use. A bathroom wall, a busy shop floor, and an outdoor terrace do not face the same moisture, traffic, cleaning, or weather conditions. Tell your supplier where the tile will be installed and whether it is intended for a floor, wall, or both. This allows a meaningful comparison between products rather than a choice based on a showroom appearance alone.

Indoor and outdoor areas

For wet rooms, kitchens, and entrance areas, consider water exposure, cleaning practices, and the likelihood of wet feet or spills. Ask for the manufacturer’s slip-related test information for the specific surface and test method; ratings from different methods may not be directly comparable. For outdoor use, confirm that the product is recommended for the local climate and installation conditions, including exposure to temperature changes. A tile’s low water absorption does not, by itself, establish that every finish or installation is suitable outdoors.

Floor, wall, and traffic requirements

Floor tiles need to suit the expected loading and traffic, while wall tiles must be compatible with the substrate, fixing method, and intended installation. In a commercial space, discuss the type and frequency of foot traffic, wheeled equipment, and cleaning products with the supplier or project specifier. Do not assume that a tile suitable for a wall is suitable for every floor application. Confirm the intended use in the product documentation and quotation.

Check the Technical Specifications

Product specifications help you compare tiles objectively and identify whether a product meets the project brief. Request the technical sheet for the exact tile, including its surface finish and size, rather than relying on a broad collection brochure. If a requirement is important to safety, compliance, or long-term performance, ask for the relevant test method and documentation. Where project specifications or local regulations apply, have the project team verify that the tile meets them.

Water absorption and strength

Porcelain tiles are commonly associated with low water absorption. Under the EN 14411 classification, Group BIa corresponds to water absorption of 0.5% or less, but buyers should confirm the product’s declared classification and documentation. Ask about breaking strength or other mechanical performance data when tiles will be exposed to substantial loads. The appropriate requirement depends on the tile format, thickness, installation system, and conditions of use.

Size, thickness, and surface

Compare nominal dimensions with the product’s declared working size, and ask about caliber and permitted dimensional variation. For example, 600 × 600 mm is a common format to use when discussing layout, but it is only an example and does not indicate that a particular product is available in that size. Tile thickness also varies by product; 8–10 mm is an example range buyers may encounter, not a universal specification. Confirm the exact thickness and suitability for the installation before ordering.

Surface finish affects appearance, maintenance, and how a tile behaves underfoot. Polished surfaces can create a different visual effect from matte or textured finishes, while textured surfaces may require different cleaning practices. View a sample in the intended lighting and inspect it from different angles. For larger projects, check several pieces together to assess the visual variation the design will show across an installed area.

Evaluate Appearance and Consistency

Product images and small samples can help with early selection, but they cannot always show how a complete floor or wall will look. Ask whether the product has a variation classification or other guidance on shade and pattern variation, and confirm the expected visual range before approval. If the design depends on a consistent color, request confirmation of the shade and caliber for the order. Keep an approved sample or record the product reference so the delivered goods can be checked against the selection.

Plan the layout and quantity

Measure the installation area and agree on a layout before finalizing quantities. The required amount can change with tile orientation, room geometry, cuts, borders, and replacement stock, so coordinate the calculation with the installer or project manager. Ask your supplier how quantities are packed and whether the quotation identifies units per carton and total coverage. Agree on a project-appropriate allowance for cutting and breakage rather than applying a single percentage to every layout.

Compare Pricing and Supplier Support

A low price per square meter is not the whole purchasing cost. Compare like-for-like products by checking finish, thickness, dimensions, packaging, stated performance, and the quantity covered by the quotation. Also clarify freight, delivery terms, payment conditions, order minimums, production or dispatch timing, and how damaged or short-delivered goods are handled. These details help purchasing teams evaluate the full order rather than one line on a price sheet.

Questions to ask a supplier

  • What is the exact product reference, finish, size, thickness, shade, and caliber?
  • Can you provide the technical data and relevant test documentation for this product?
  • Is the tile recommended for my stated application and installation conditions?
  • What are the packaging quantities, order minimum, estimated schedule, and delivery terms?
  • How should I inspect the shipment and report any discrepancy or damage?

Clear answers make it easier to compare suppliers and reduce avoidable misunderstandings during ordering. For a substantial or phased project, confirm whether later orders can be matched to the same shade and caliber, and do not assume that future production will be identical. Ask how samples relate to the quoted product and whether the quotation covers the exact selected finish. Keep technical approvals and commercial terms together in the purchase record.

Common Buying Mistakes to Avoid

  • Choosing by appearance alone: A visually appealing tile may not suit the floor, wet-area, or outdoor requirements. Verify the product’s intended use and relevant documentation.
  • Comparing different specifications: A price comparison is unreliable if the products differ in format, finish, thickness, or packaging. Normalize the details before making a decision.
  • Ignoring installation compatibility: Substrate preparation, adhesives, grout, and installer practices influence the finished result. Coordinate the tile choice with the installer and project specification.
  • Ordering without confirming shade and quantity: Approve the visual selection and calculate the order for the final layout before bulk purchase. Clarify how additional quantities will be handled.
