Tiling prices can change from one project to another because every site is different.
A simple open floor with a clean, level surface is normally easier to price than a bathroom renovation with old tiles, waterproofing, plumbing points, wall tiles, floor tiles, trims, and detailed cutting.
Large - format tiles may also cost more to install because they are heavier, less forgiving, and need a flatter surface. Mosaics, herringbone patterns, diagonal layouts, and feature walls can also take more time because there is more measuring and cutting.
The surface condition matters as well. If the floor or wall needs cleaning, levelling, priming, waterproofing, crack repairs, or old tile removal, the cost can increase. That preparation is not just an extra. It can be the part that helps the tiling job last longer and look better.
