Can tiles be installed without joints?

When laying tiles on the floor or wall tiles indoors - is it possible to avoid joints? The joints between the tiles have always been left. They were the same size and then sealed. They were not done for beauty, but for other more practical reasons. In fact, there is no such thing as seamless tile in the literal sense. Basically, when we talk about seamless tiles, we are talking about rectified tiles that still require joints, quite thin, sometimes almost invisible because these thin grout lines ideally measure only 1 millimetre or even less.

This type of tile is really loved by designers and very trendy because of its aesthetics. On the other hand, this type of tile requires a very precise and accurate installation to ensure the quality and stability of the whole installation. That said, a rectified tile installation requires the work of a professional. There is no need to economize on surface leveling, adhesives and the work of the tiler. If a tiler convinces you to refuse rectified tiles because it is useless, probably you hire an amateur. Thick joints can hide even a major flaw in the work, while almost seamless rectified tile will show the smallest defects.

In addition, it is forbidden or, at least, not recommended (depending on the specific country) to install ceramic tiles completely without joints. Especially in places with high humidity and sudden temperature changes, such as bathrooms and shower stalls. It is necessary to keep the joints between tiles in new houses, the building shrinkage can cause defects in the monolithic coating. Also it is forbidden to lay a tile without joints on the heated floor. Under the effect of temperature changes, the tiles expand and may explode. Therefore, in all the above cases, the minimum width of the joints must be at least 2-3 millimeters. Outside, of course, it is necessary to preserve the larger joints: tiles without joints are especially unsuitable for terraces, balconies, patios etc.

In the course of their manufacture, rectified tiles have passed an additional stage. The edges of the rectified tiles are cut with a diamond disk, they are perfectly straight and of an absolutely identical size. Thus they allow for very thin, almost invisible joints.

There is another type of seamless tile: clip tile. This type of tile does not really have joints because the tiles are joined to each other by simply interlocking. Neither adhesives, nor sealants are used. This type of tile allows it to have a homogeneous and monolithic covering. However, this type of tile is less solid, less resistant and probably less durable. In addition, the clip tiles offer a fairly limited choice of colors and finishes.
