Modern interiors increasingly favor continuous flooring without visible dividers. That is why many homeowners ask: is it possible to install porcelain stoneware without a threshold, and is it technically correct to do so?
Eliminating thresholds creates a visually unified space and makes rooms appear larger and more contemporary. However, this solution requires careful planning and a clear understanding of the material’s characteristics.
To determine whether a threshold is necessary when installing porcelain stoneware, several factors must be considered: the total area, the condition of the substrate, temperature variations, and the type of screed.
Porcelain stoneware is strong but rigid. While it does not easily deform, the base underneath may experience slight movement. That is why completely joint-free installation without expansion gaps is not recommended.
At the same time, porcelain stoneware without a threshold between rooms is entirely possible if technical requirements are met and expansion joints are properly planned.
Installing porcelain stoneware without thresholds is suitable under the following conditions:
In such cases, tile without transitions between rooms looks aesthetically pleasing and enhances the sense of continuity.
Installation of tiles without transitions requires precision. The substrate must be perfectly leveled, and there should be no height differences between rooms.
Even when no threshold is installed, a minimal grout joint between tiles must remain. This allows for thermal expansion and reduces the risk of cracking.
In larger areas, expansion joints are essential. They can be positioned under furniture or in less visible zones to preserve the seamless appearance.
Special attention is needed when porcelain stoneware is installed without a threshold at an exit to a terrace. In this case, slope for water drainage, frost resistance, and moisture resistance must be carefully considered.

Outdoor installations typically have stricter technical requirements than interior spaces.
Although installation without thresholds looks modern and clean, potential risks should be considered:
Careful evaluation of the base and overall layout is essential before deciding on a seamless approach.
In certain situations, a threshold remains a practical and technical solution:
In these cases, the threshold serves a compensatory rather than decorative purpose.
So, is it possible to install porcelain stoneware without a threshold? Yes, provided that technical standards are followed and expansion joints are properly planned. Porcelain stoneware without a threshold between rooms is a modern and visually appealing solution, but it requires a well-prepared substrate.
