Finding an Ideal Standard replacement seat means distinguishing ranges, rather than finding one size for the brand. Historic and recent toilets may share a manufacturer but have different outlines, contact points and hinges. This guide compares four common range names and links to their model pages. It helps organise the search; confirming a replacement still requires the exact installed toilet.
All ranges and replacements for Ideal Standard
Conca: inspect the rear mounting surface
For classic Conca, check the raised sloping rear area and hinge arrangement together with the outline. A rectangular shape alone does not confirm compatibility. The Conca name may appear on different collections and versions: make sure the listing specifies the installed bowl. The existing Conca blog guide covers its mounting details and replacement options.

Tesi: distinguish classic Tesi from Tesi Nuovo
The Tesi page includes proposals for different versions, including Tesi Nuovo/New and special configurations. Do not carry a compatibility claim from historic Tesi over to the redesigned version. Look for the complete name, bowl photos and mounting information. The dedicated Tesi article already explains how to navigate the two ranges.

Ellisse: an oval outline is not a model name
Rounded bowls from many ranges can look similar. Use the Ellisse model page and compare the front and rear profiles, hole positions and seat supports. The catalogue includes different materials and finishes; choose a product expressly listed for Ellisse rather than a generic oval seat with nearby dimensions.
Connect: check the complete designation
Read Connect together with the full version stated on the listing. Do not extend compatibility to other toilets that share a word in their name. The Connect section offers standard and soft-close seats described as original or dedicated. These describe the replacement product; the match to the bowl must still be confirmed.
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.
Replacement questions
Are the brand and measurements enough?
No. One maker produces many ranges and versions. Measurements can rule out an unsuitable product, but the outline, supports, hinges and declared compatibility must also match.
Can I choose another seat to add soft-close?
Only if the product is expressly intended for your range and version. Soft-close cannot correct an incompatible outline or mounting system; check the listing and supplied hardware.
