A broken hinge does not always require a complete new seat. However, the toilet brand alone does not identify its hinge: original and dedicated seats for the same pan may use different hardware. Start with the installed seat’s code and purchase details.
Locate the damaged component
Distinguish the pan fixing, mounting plate, pin, bush and hinge body. A moving base may indicate an anchor problem rather than a broken hinge. A cracked hinge or damaged attachment in the ring cannot be repaired by tightening the pan bolt. Stop using an unsupported or broken assembly.
Identify the seat as well as the toilet
Series names such as Conca, Tesi and Starck do not specify a single hinge. Seat maker, material, version and release system matter. Photograph both hinges and their connections to ring and lid, keeping visible codes and removed parts. Similar appearance and spacing do not prove interchangeability.
Sintesibagno kits have specific conditions
Some kits serve seats previously bought from Sintesibagno; others are limited to named lines or original parts. For an older purchase, provide the order or product code and requested photographs, then obtain confirmation before ordering. A kit described for the SMILE line is not universal for all soft-close seats.
When a complete seat is needed
A separate hinge is useful when the remaining seat is sound and the exact spare exists. Damaged attachment sockets or an unavailable kit may require complete replacement. Do not drill new sockets, glue load-bearing parts or improvise hinge adaptations. Follow the exact kit’s installation and tightening instructions.
Replacement questions
Can ordinary hinges be upgraded to soft close?
Only if the manufacturer specifies an appropriate kit for that exact seat and all its connections.
What if I cannot identify the installed seat?
Send seat and hinge photographs, visible codes and purchase details. If the toilet is also uncertain, use Sintesibagno identification first.
Model pages and Sintesibagno.shop examples
These links show examples in the dedicated catalogue for a toilet that has already been identified. Check current availability, lead time, material and included fittings on the product page. A single example does not represent the whole range.

Checks before ordering
- Confirm the toilet brand, range and exact version. The logo identifies the maker but does not by itself identify the model or the right replacement.
- Compare the complete outline, rear profile and support points. Record length, maximum width and fixing-centre distance as checks, rather than treating measurements as proof of fit.
- Check whether the fixings install from above or below. The hardware must suit both the bowl and the new seat hinges.
- Read the material, closing and release specifications. Soft-close and quick-release are different features and do not make seats from different ranges interchangeable.
- Check the exact named finish and colour. Photos, lighting and screens cannot confirm a ceramic shade. Check included accessories and delivery time too.
