HARO WC seats always fit..

When choosing a toilet seat, decisions need to be made about material, colour, design and functionality. The size of the ceramic is also crucial. HARO offers a suitable toilet seat for the majority of commercially available ceramic models. Special dimensions are also no problem.

Take measurements of the ceramic

Judge the shape of the WC ceramic appliance.
Is it oval, straight (D-shape) or angular?
Choose the right toilet seat based on the shape.


1 Hole spacing

Measure the distance between the fixing holes of the ceramic: centre hole to centre hole. The dimensions in the HARO product list apply to ceramics with a hole spacing of 155 mm. If the hole spacing differs from this DIN dimension, you should choose a toilet seat with an eccentric hinge if possible.

2 Length

Measure the length of the ceramic:
Centre hole to centre front edge of ceramic (maximum). The length of a toilet seat depends on the length of the set and the adjustment range of the selected hinge. (Length of seat / adjustment range of the hinge)

The length range covered by a seat can be found in the dimensional drawing of the respective model in this product list. Some hinges from HARO have an asymmetrical design (e.g. bow hinges). The length of these hinges is also influenced by the mounting direction, i.e. two lengths can be realised: Length 1 or 2
