Major renovation of the bathroom, including elimination of the moisture source from neighbors and full waterproofing

1. Project and Technical Calculations:
   • Major bathroom renovation involving plumbing replacement and remediation of severe moisture and mold issues, originating both internally and from neighboring units.
2. Dismantling of Existing Finishes:
   • Discovery of critical defects: Complete tile removal revealed a total lack of waterproofing in the original bathroom.
   • Removal of multiple layers of mold and mildew beneath the tiles that had accumulated over the years, posing a health threat to the residents.
   • Breaking down concrete to clear the subfloor base.
3. Installation of Engineering Systems:
   • Eliminating an external leak (2 weeks): Identification and a two-week negotiation with neighbors to repair a defective leaking pipe in their unit that was dripping directly into our bathroom.
   • Bathroom waterproofing: Creating multiple layers of new, reliable waterproofing within the bathroom.
   • Waterproofing of the adjacent wall: Identification and resolution of the peeling paint issue on the living room wall adjacent to the bathroom. Additional multi-layer waterproofing was applied to the living room side of the wall to completely eliminate moisture seepage.
   • Bathtub installation: Mounting of a new bathtub with mandatory soundproofing to eliminate unwanted noise during use.
4. Substructure Installation:
   • Cleaning and preparation of the concrete base for the new tiles.
5. Finishing and Furnishing:
   • Installation of new plumbing fixtures and final bathroom finishing.
