Mid-century modern Lavabo (2) - Ideal Standard - Ceramic - Gio Ponti Bathroom Set

Split translated to English:

Splendid and rare paired set of historic author-made sanitary fixtures in white ceramic, Pontlav series (also known as the Oneline / Zeta series), designed by master Gio Ponti for Ideal Standard in 1953 [intOndo Lavabo Pontlav Gio Ponti 1953]. An absolute icon of mid-century modernism and Italian industrial design.

The lot comprises:
1. Trapezoidal sink with the unmistakable smooth basin designed by Ponti to accommodate the natural motion of the arms, complete with its original tapered sculptural column and the three-hole faucet group dating from the era.
2. Coordinated ovoid bidet of the same series. The bidet is currently adapted with a modern mixer via chrome caps that cover the original three-hole predisposition (easily restorable).

Details of authenticity and historic marks (documented in photos):
The set features a rare and extraordinary mapping of original factory marks that certify its authenticity:
• Historic blue fire stamp "Standard" in vintage cursive on the side (dating from before the company changed its name to Ideal Standard).
• Raw engraving of the elongated cursive "Z", identifying mark of author-produced Gio Ponti–signed Series Z.
• Casting codes and mold traceability ("Z3") impressed in the ceramic before firing.

Conditions:
The sanitary fixtures are intact, structurally sound, and free from deep cracks or porcelain pitting. They display the usual signs of time and limescale consistent with their age and use, easily removable with a thorough cleaning. Original sink hardware included.
