We designed a luxurious apartment in Krakow that is exceptional both functionally and aesthetically. In particular, our bathroom design with a shower is exceptionally modern. The bathroom is fitted with beige porcelain stoneware tiles, a wooden floor, and white sanitaryware with cabinetry. The bathroom floor is identical to the rest of the apartment. A backlit mirror above the washbasin visually enlarges the space, and a pendant lamp with up-and-down lighting was designed above the washbasin. The cabinet above the enclosure of the in-wall toilet frame was designed with a division referencing the layout of the wall tiles. Our interior design project of a luxurious large apartment in Krakow is modern, functional, and aesthetic. It is an ideal solution for those seeking an exceptional interior design.
