L'invention concerne un accessoire pour toilettes et une installation sanitaire permettant d'extraire l'air putride de la cuvette de W-C. Cette installation comprend un support de siège de toilettes (18) monté sur la cuvette (12) ainsi qu'un siège de toilettes (20) monté pivotant sur le support (18). L'air putride est aspiré à partir de la cuvette (12), à travers une voie d'écoulement qui s'étend en partie à travers le support (18). Un clapet de non-retour est monté dans la voie d'écoulement. L'écoulement de l'air est provoqué par un ventilateur d'extraction (42) commandé par un commutateur (44) actionné au niveau du siège. L'accessoire comprend une partie des composants nécessaires pour modifier des toilettes classiques selon l'invention.
