Interior can look modern when using various combinations of ceramic tiles. Monochrome walls and mosaic floors, relief wall tiles and parquet, marble countertops, and floor coverings. Combinations of light and dark, smooth surfaces with textured materials are just a few techniques employed by renowned designers worldwide.
Kitchen:

Currently, the most popular color tones in kitchen design are white, gray, and beige. Calm neutral colors visually expand the space and add brightness. Consider combining light mosaic tiles with natural motifs and solid dark flooring. Such solutions are often used in minimalist-style interiors, with Scandinavian-style furniture and black faucets.
Another option is the combination of white and gray, using rectangular tiles to create a relief wall. This choice won't rely on contrasts; instead, its monotony will maintain harmony.
For those who prefer an open kitchen, an American-style option can be considered. Built-in furniture in brown tones and ceramic tiles. To add accents to the interior, you can use tiles with geometric patterns reminiscent of 19th-century modernism.
Living Room:

For the living room, we suggest considering a more rigorous style. Porcelain stoneware or wall tiles in synergy with warm-toned ceramic parquet. To add coziness to the room, choose furniture in white color, metal tables, and lamps, and incorporate geometric shapes into the space.
Bathroom:

The bathroom is often a small space, but it can be visually enlarged with neutral colors and tile combinations.

To create an elegant and enigmatic interior, we recommend opting for monochromatic designs. Black and white are foolproof shades for the bathroom. Ceramic tiles can act as decor if framed with decorative profiles.

For those who appreciate meticulous design, there is an option using surfaces in saturated colors. For example, emerald-green tiles with white and brown veins will create a sophisticated bathroom design.
To finish, we suggest adding a light floor, black sinks, and gold accents on the faucets.
