The Onza collection the Spanish company's Harmony by Peronda range features three different designs, which can be combined together to create various raised patterns.
One design resembles a standard bar of chocolate, and features a regular raised grid that creates small squares.
The second is made from three rectangular sections, and a third features a large central square flanked by smaller, more slender rectangles.
All of the ceramic tiles feature the same cut-out corner section, allowing them to be slotted together regardless of the angle.
"Onza is composed by just three ceramic pieces with invisible joints, allowing infinite compositions when assembled thanks to their modularity," said the studio, which previously designed freestanding copper, marble and oak kitchen units.
"It is possible either combining repeatedly one of the pieces or playing with the three options," it added.
The collection is available in three different colours: grey, orange or white, which have been designed to "evoke different sensations". Tiles can be placed at right angles to one another, or laid in slanted configurations.
The studio has previously created a collection of similarly modular hexagonal floor tiles, designed to imitate the psychedelic patterns seen through a kaleidoscope.
Patterned tiles by other designers include Lindsey Lang's range for walls and floors influenced by textile patterns and symbols found across London's transport network, and Tom Dixon's collection inspired by the city's architectural features.
The Bouroullec brothers have also designed a collection of three-dimensional textured porcelain tiles for ceramics brand Mutina.
