Karoistanbul produces handmade ceramic tiles

A Journey in Restoring Aesthetic Value to Forgotten Tiles

At Karoistanbul, we're proud to have played a role in reviving encaustic cement tiles, which were once almost extinct.

We're dedicated to reproducing these handmade floor and wall tiles that were widely used in many cultures in the past. By combining our years of workshop experience with our designers' modern and visionary approach, we bring new aesthetic value to these nearly forgotten tiles.
With our modern techniques, we're able to create bespoke productions in any desired pattern, color, and size.
Karoistanbul gets inspired by the past and aims to improve 
the quality of its products and to expand the range by
using today's technology.

history of Karoistanbul

Our History

A patterned tile which is a typical Mediterranean material made by pouring cement, marble powder, aggregate and pigment into the mold and pressed with high pressure, also known as ‘’carreaux de ciment’’, started in France in the 1850s, spread all over the world from the Mediterranean Region to North Africa and from there to the Far East.In the 1950s mosaic and tile manufacturers had started to be uncapable to compete with industrial products such as ceramics, linoleum, granite, which were relatively quicker and easier to produce than patterned mosaics tiles, they became unable to make production in a very short time. As a result of a forced defeat they had to leave this area.


The foundations of Mavi Pencere were laid by Painter Zekai Bostancı in a small art studio in Istanbul Moda.


This small atelier, besides painting, began production of stained glass, mosaic panels, and ceramic tiles.


R&D studies were initiated on cement tiles, and all findings related to the subject were documented over the years. As a result, a fading craftsmanship and culture was preserved.


The team started production of this traditional material while enhancing its technical and aesthetic aspects. They later institutionalized their efforts under the name of Karoistanbul.


Karo İstanbul has a significant export volume in floor and wall coverings. It is a preferred brand abroad, thanks to the quality and diversity of its products. It offers a wide range of options to its customers by producing floor and wall coverings suitable for different styles and needs.
