Start by deciding which country of origin actually fits your project’s design intent and budget, since that single choice narrows the entire search — Italy for design leadership and large formats, Spain for strong mid-range value, Turkey for competitive pricing, or Portugal for decorative and patterned work. Trying to compare all four equally without a priority is where most buyers get stuck.
Once you’ve picked a direction, verify before you commit: ask for the manufacturer name, collection name, and batch number rather than taking a seller’s word that a tile is genuinely imported. A few minutes of verification upfront saves you from a costly mismatch discovered only after installation, when a second batch doesn’t quite match the first.
