A wobbly toilet seat is not just annoying, in the long term it can also cause damage to the seat and toilet. If your toilet seat is wobbly, it’s usually because of a loose fixing. In this case, you have the following options:

Check and lock:
If the fixing is accessible from the bottom, check whether everything is tightened properly. If this is the case, you can screw another nut onto the existing thread, further fastening the fixing.
The technical jargon for this process is locking a nut.

Retightening:
If the toilet seat fixing is not visible from the bottom, a different process is required. In this case, there should be a screw on the fixing that you can see at the top of the toilet. You can retighten it, thus providing additional stability.

Assembly kit:
If the toilet seat still wobbles despite these measures, you should buy an appropriate assembly kit. You can find these in specialist sanitary equipment retailers and in DIY stores.

How long you can keep using your toilet seat without problems depends on its quality and how frequently it is used. As an everyday sanitary product, however, it is advisable to replace your toilet seat at regular intervals: Every four years is a recommended benchmark for this.

Especially if they are cleaned incorrectly with aggressive or chlorinated cleaning products, toilet seats usually age more quickly. The surfaces become porous and provide a good target for dirt and bacteria. If this happens, the toilet seat should be replaced with a new one immediately.

To replace your toilet seat, you should first check whether the toilet seat’s fixing is accessible from under the toilet ceramic.

  • If the fixing is accessible from the bottom, it is probably a classic nut-and-bolt fixing. Despite the many different designs, the way of installing this kind of fixing is usually very similar: To loosen the fixing, simply unscrew the nut and then remove the toilet lid from the ceramic.
  • If your toilet ceramic is completely closed at the bottom, the fixing will only be visible from above. To demount the toilet seat, you have to turn the screw on the top anti-clockwise. When doing this, part of the fixing might fall into the toilet ceramic. The cavity is big enough, though, and the part that has fallen inside won’t impede you during the installation of the new toilet lid. When buying the new toilet seat, make sure you get a model with a special top fixing.

When buying a new toilet seat, you can choose between different toilet seat shapes. The preferred seat shape is very different from region to region. By and large, the shape of a toilet seat can be put in the following four categories:

  • Oval / Universal
  • D-shape / U-shape
  • Square
  • Pointed / V-shape

Even in quality products like our toilet seats, there can sometimes be defects.

  • If your HARO seat is defective, please contact the plumber that performed the installation or the specialist retailer from whom you bought the seat.

During the production processes, we regularly test the load-bearing capacity of our toilet seats. Furthermore, all our toilet lids not only meet the strict DIN standards, but also our internal requirements, which go beyond the DIN regulations: The relevant requirement of DIN 19516 Test A is a load-bearing capacity of 175 kg. Our minimum requirement is far higher. The internal Hamberger Sanitary standard is 250 kg. Some extra-strong models can even bear loads of nearly 450 kg.
