Wir liessen eine Regen Dusche einbauen. Von der Offerte bis zur Endmontage lief alles super perfekt profimässig und sehr freundlich an. Super Arbeit.

J’ai contacté ce monsieur pour un débouchage de douche, il a été très consciencieux et rapide dans son travail et la facture n’étais pas salé, il a également rénové la salle de bain de mes parents qui sont très satisfait du résultat et du professionnalisme de ce jeune homme. Je le recommande fortement.

Entreprise familiale disponible, professionelle et à l'écoute. Je recommande sans hésiter BS Halili Sanitaire Sàrl pour leur sérieux. Merci encore pour tout. Juan Rosa
