The platforms of Line 3 were among the first to receive a metallic bodywork after 1952, while those of Line 5 were renovated after 1969 by adopting the Mouton-Duvernet style with vertically-aligned multi-toned tiles, cutting radically with the dominant white of the original metro, as well as the light frames characteristic of this type of arrangement, which was then supplemented with Motte style seats and red sit-stand bars.

Larger Mouton style tiles placed vertically also cover certain outlets of the access corridors to Lines 3 and 11.

As part of the RATP Renouveau du métro programme, the station's corridors and the platforms on Line 5 were modernised on 28 June 2010,[1] which notably allowed the renewal of lighting and earthenware tiles, the installation of new signage, a sales and comptoir-club counter, as well as the creation of four automatic ticket machines, anticipating the redevelopment programme by the City of Paris of the Place de la République.

[2] These latest above ground works are suspected to be the cause of numerous water leakages in the station, destroying the repairs completed three years earlier.

The advertising frames are white and cylindrical, and the platforms are equipped with Motte style seats as well as blue sit-stand benches.

The platforms of these two lines, slightly curved at the western end, are furnished in the style Andreu-Motte and have a yellow light canopy, benches in flat orange-yellow tiling (except the platform for Pont de Sèvres almost deprived of benches but with a corridor opening treated with the same tiles) as well as yellow Motte seats.

For each stopping point, the vault is elliptical, and the name of the station is written in Parisine font on enamelled plates.
