Torni’s interior reflects the hotel’s time of birth: functionalism, Jugend and Art Deco are strongly present in its rooms and along the corridors. The current interior design stems from the hotel’s original architectural style, suprematism, and the stylistic features that give their finishing touches to its ambiance come from functionalism.

The suites exude Art Deco, and the Standard and Superior rooms provide a chic setting for a good night’s sleep. Functionalism also flavours the scenic rooms at the top of Torni.

Torni’s floors 1–5 are decorated with sofas, divans and armchairs that have been especially designed for Torni, and are made of dark-grey etched birch and upholstered with fine wool. Furniture and lighting choices echo classic functionalism: office chairs designed by Mart Stam and table and floor lamps by Pierre Chareau. The Wassily chairs and tables found in the lobby are designed by Marcel Breuer.

The rooms get a splash of colour from brightly coloured blankets, throws, pillows and lights. They also set the stage for the works of art mainly acquired through Ateljee Bar’s exhibitions.

The spacious and airy scenic rooms feature glass-partitioned en-suite bathrooms. Traditional curtain solutions have given way to large mirrored surfaces that extend the space and reflect the scenery.

The bathrooms are built around the Red Square theme by Kasimir Malevich, the creator of suprematism.

The Kyllikki wing was attached to Torni later. It is the fruit of the National Romantic Style, which takes its cues from the spirit of Kalevala, the Finnish national epic. Today, the Kyllikki wing has been restored in Art Deco style. The wing was completed in 1903 and represents Art Deco, also known as Jugend, a comprehensive artistic style that evolved into a nationally typical style in Finland. It became the first independently born arts and design style, and as such established the foundation for Finnish design.

The walls of the rooms in the Kyllikki wing are decorated in keeping with the natural theme that can be seen throughout the building. Its colour scheme is based on colours that were typical of the era: wine reds and forest greens. The choice of furniture and lighting also echoes the spirit of Jugend and the National Romantic Style. All office chairs in this building are designed by Eliel Saarinen, as are the House Collection and Huvila furniture that are found in the suites. The chandeliers in the Luxus rooms are genuine antique candelabras from the Art Nouveau era, and the round, ball-shaped lamps in the basic rooms are designed by W. Brand.
