Mount a toilet seat


It is in the nature of man that we need to use the toilet every day. Each individual seeks the quiet place several times a day. Especially in households with several people this means a regular continuous use of the toilet. This then leads to a certain amount of wear and tear, which manifests itself to different degrees in the various components of a toilet. One of the most affected components is the toilet seat. Therefore, below we have created a guide for you to quickly mount a toilet seat.

Especially the toilet seats are pretty much strained

Day in, day out, especially the toilet seat is massively strained. So toilet seat and lid have to endure a lot:

  • constant and daily frequent opening and closing
  • accidental dropping of toilet seat or lid
  • especially with men in the household often splashed with water and urine
  • associated with an intensive regular cleaning with correspondingly aggressive means

Although we all hold our sessions several times a day on the locus, we do not even notice how much toilet seats and lids are being used. This is the quiet place to take for granted.

Typical problem with toilet glasses: they wobble at some point

Most people have already made their experiences with a toilet seat, which constantly wobbles. Even re-tightening the not so appetizing screws usually helps nothing - despite overcoming, which costs the short-term repair many people. But that's not enough.

Further damage to toilet goggles

Over time, toilet seats also scratch. In addition, they become dull and dull, which is why after a few years they look anything but handsome. Due to the occasional dropping of the toilet seat and the toilet lid, one or the other crack creeps into the plastic toilet seat, causing you to uncomfortably constrict your buttocks.

Not to forget the hygienic aspects

These deficiencies are rounded off by deposits that collect under the rubber discs that are inserted between toilet seat and toilet ceramic. From a hygienic point of view, it makes sense not to renew the toilet seat until it has visible damage or deficits. So that it does not come back to a shaky toilet seat, we have subsequently created an assembly manual for the toilet seat.

Step-by-step instructions for mounting a toilet seat

  • new toilet seat with fixing material
  • possibly rust remover
  • possibly cleaning agent or decalcifier
  • Wasserpumpenzange
  • matching ratchet nuts with extension and ratchet
  • Rubber gloves in heavy deposits

1. Preparatory work

If you want to install a new toilet seat, of course, the old toilet seat with lid must first be dismantled. If it is an older model, the connecting screws or threaded rods may be metal products. They are then highly likely to be attacked by massive corrosion.

Therefore, you should spray metal screws or threaded rods on the eve of the actual installation generously with rust remover. In newer toilet seats are usually plastic thread, on each of which a wing nut is screwed from below. Then of course you do not have to spray rust remover.

2. Remove the old toilet seat

The next day you can now remove the toilet seat. The screws are located behind the seat at the height of the hinges for the toilet lid. The threaded rods are even part of the hinges, because the corresponding fishing rod is firmly connected to the head of the threaded rod.

Now turn the wing nuts out from below. If they are stuck, attach the water pump pliers. If it is a traditional nut, use the ratchet. Completely unscrew the nuts (left and right from the back bottom of the sanitary ware). Then you can lift the toilet seat with lid just up from the holes in the toilet bowl.

3. Cleaning the toilet ceramic

Often you can find just under the rubber washers (between toilet seat and toilet ceramic) significant deposits of lime and urine stone, in addition to other dirt particles. It is therefore advisable to clean the toilet bowl explicitly at the holes for the toilet seat. You can use the same cleaning and descaling agents that you use to decalcify the toilet.

4. Mount the new toilet seat

Most toilet goggles sets (toilet goggles with toilet lid) are already connected together and you just have to put the two threaded rods through the back holes of the toilet ceramics. But please do not forget the rubber washers. These are on the one hand to seal against moisture, on the other hand ensure the necessary maintenance of the toilet seat. Now tighten the nuts slightly, but do not tighten them yet (the toilet goggles must be moved).

If you still have to assemble the toilet seat and toilet lid, first insert the threads with the hinge hinges on top through the toilet seat, then slide on the rubber washers. Now, the threaded rods are pushed through the holes of the toilet ceramic and also only slightly screwed. The hinge heads must turn.

The two hinges point inwards, towards each other. Turn both at a 45-degree angle forward. Then put the toilet lid on one side. Now turn the whole lid slowly towards the other hinge. Pins and hinges now point to each other and can be intertwined with very gentle force. Then both hinge heads are automatically aligned.

5. Fix the toilet seat and toilet lid and screw tight

Now align the toilet seat exactly in the middle (side as well as in the depth), before finally tightening the nuts from the bottom of the WC ceramic. Tighten the nuts so that you do not over-tighten the threads.

Tips & Tricks

You can also connect the new mounting of a toilet seat with the retrofitting of a soft-closing mechanism. There are models in which you can swap the toilet seat at any time, but the threaded rods remain firmly connected to the toilet bowl. The threaded rods are connected via a simple plug-in system for locking with the toilet lid.
