Installation requirements differ significantly between tile formats. Large-format tiles (generally 12x24 inches or larger) demand a perfectly level subfloor, as even minor deviations can cause 'lippage,' where tile edges are uneven. They require specific large-format mortar to support the tile weight and ensure consistent coverage. Conversely, mosaic tiles are mounted on mesh sheets; their smaller size allows them to conform slightly better to minor surface irregularities. Both require correct grout selection and proper waterproof membranes in shower or wet area environments.

How do installation requirements differ between mosaic and large-format tiles?
Large-format tiles require a very flat substrate to prevent cracking and lippage, whereas mosaic tiles are more forgiving of minor surface variations due to their smaller footprint. Large-format tiles also necessitate specific thin-set mortars designed for larger surface areas.
