TEUCO toilet seats: original replacements for Outline and Wilmotte
TEUCO brought together bathroom wellness, hydromassage, materials research and design. Alongside baths and showers, the Guzzini family brand also developed sanitaryware collections. Outline and Wilmotte offer different approaches to toilet design, each requiring a specific seat.
Start by identifying the series and checking the variant. This page brings together one Outline replacement and two Wilmotte options, with different closing mechanisms.
Wilmotte: a D-shaped outline and a geometric body
The Wilmotte series takes its name from French designer Jean-Michel Wilmotte. Produced in wall-hung and back-to-wall floor-standing versions, it combines a squared lower body with a D-shaped outline, echoed inside the bowl. The seat must follow that design: being D-shaped alone does not establish compatibility.
The listed replacements specify Wilmotte, toilet X13/X15. Both are white, classified as original, name TEUCO as manufacturer and use thermosetting Duroplast resin. Their hinges differ: one has standard stainless steel hinges, while the other has stainless steel Soft Close hinges. Select the intended closing action before ordering.
Outline: oval curves and the K170 reference for toilet X35
The Outline series has an elongated oval profile and more rounded surfaces. A distinctive detail, particularly visible on the wall-hung toilet, is where the lower curve becomes a straight section running towards the wall, parallel to the floor. A correctly selected seat follows the upper outline of the bowl.
The replacement is identified as Outline K170, for toilet X35: white Duroplast, stainless steel hinges, classified as original. The product specifies VITRA as the seat manufacturer. This applies to that particular item and does not establish compatibility with other Vitra seats. Soft Close is not stated for this Outline variant.
Original TEUCO replacements, materials and availability
These three options are classified as original. They should not be confused with a general range of universal seats or dedicated coated-wood replacements. Their stated material is thermosetting Duroplast; stainless steel hinges alone do not indicate a soft-closing mechanism.
A catalogue entry may be out of stock. Check the individual Sintesibagno.shop page for current availability and ordering conditions. The number of listed variants does not indicate how many can be ordered immediately.
Finding the correct TEUCO seat
If you know the series with certainty, open its model page and check the toilet references and variant specifications. Apparent shape, partial measurements or resemblance to another seat do not confirm interchangeability.
If you do not know the model, use the Sintesibagno toilet seat identification service before purchasing. Specialist staff can help identify the toilet and the relevant replacement.
Frequently asked questions about TEUCO seats
Do Outline and Wilmotte use the same seat? No. They are separate series with different references: X35 for the Outline described here and X13/X15 for Wilmotte.
Do all TEUCO seats have Soft Close? No. Among these options, Soft Close is specified for one of the two Wilmotte versions.
How should these Duroplast seats be cleaned? Use water and neutral soap, then dry with a soft cloth, including the hinges. Avoid abrasive or aggressive cleaners. When using strong cleaners inside the toilet, leave the seat and lid raised to protect them from fumes.
