Cistern as surface-mounted version: Advantages and possibilities

you are - as their name implies - on the plaster: Aufputz cisterns have received in recent years, great competition from pretext installations. These flush-mounted cisterns are popular for optical reasons. But the surface-mounted cistern is in terms of modernity in nothing. It has numerous advantages, offers various design variants and also sophisticated technology.

What is a flush-mounted cistern?

This cistern is visible in the bathroom and is mounted on plaster and tiles on the wall. As a result, the surface-mounted cistern is visible just above the toilet bowl. Only a few years ago they were often attached to the ceiling. With the drop height, more pressure and speed should be generated in the toilet flush. Trigger was often a chain or string. Today's surface-mounted cisterns have an actuator plate.

In many aspects, the cistern on the plaster is better than its reputation. Thanks to the latest technology, he is in no way inferior to his relative in the front wall. The surface-mounted version also reduces the amount of water consumed, is durable and robust, but also quietly designed. Surface-mounted cisterns can have the following functions:

  • Dual flush
  • Start-stop function
  • Stormwater isolation
  • Noise isolation

Two-flush technology has two separate chambers inside which provide a different amount of water. The small flush often only consumes about three liters of water. Up to six liters can be supplied in the second rinse cycle.

The rinse-stop function is also available for the flush-mounted cistern. Here, the water supply can be stopped manually by pressing the rinse button a second time. So the owner can decide for himself how much water he uses in the toilet flush.

According to calculations most of the drinking water of German households ends up in the toilet bowl. About 40 liters per person are consumed daily here. Dual flush and stop button help considerably in saving water.

Advantages and Disadvantages of the Surface-mounted Cistern

The option of visibly attaching the cistern to the wall in the bathroom has numerous advantages. So these cisterns are much easier to install. No complicated pre-wall installations with wet construction or dry construction techniques are needed here. The box is simply mounted behind a wall-mounted or standing WC.

The home improvement can also clean and maintain the surface-mounted cistern with much less effort. Because once something breaks in the flush, the cistern is freely accessible. This makes the surface-mounted cistern especially in guest and secondary toilets in the house a particularly suitable variant.

The disadvantage is, especially in small bathrooms, that the surface-mounted version remains optically visible and also takes up space. In small bathrooms, a hidden installation in the front wall is the better alternative. These flush-mounted models use less space, but require more effort in installation and care. Both variants hardly differ in terms of volume - both surface-mounted and concealed cisterns work quietly, but not completely silently.

Anyone who has a floor-standing WC in the bathroom must inevitably choose a surface-mounted cistern. The different connections are not compatible with a flush-mounted cistern.

Different shapes for different baths

Surface-mounted cisterns are available in numerous different versions. The handyman has on the one hand the choice between different materials. Possible ones are:

  • Plastic
  • Sanitary Ware
  • Sanitary Porcelain
  • Duroplast
  • Stainless Steel
  • Brass

Most consumers choose a plastic flush-mounted cistern, which is often inexpensive, yet offers break resistance and impact resistance , Plastic is also light but strong. High quality is sanitary ceramics or sanitary porcelain. Stainless steel and brass are usually only used in special design bathrooms.

But the surface-mounted cistern can also vary in terms of color. It does not always have to be the classic white. Beige is just as popular as well as colorful and colorful variants, if it fits into the overall concept of the bathroom. In addition, many manufacturers offer not only the classic square cistern. Shapes with rounded corners as well as corner shapes are possible here. A wall-mounted flushing cistern can still be installed in a low-hanging or high-hanging position, the first being much more common.

The first water closet was invented by Sir John Harrington in 1596 in England - including a cistern. But only Alexander Cumming added an s-shaped drainpipe, which helped the toilet to break through. The first surface-mounted cisterns were made of wood.

Manufacturers and suppliers

Most home improvement stores offer various surface-mounted cisterns, but online shopping is also possible. Likewise, a cistern can be ordered directly from the manufacturer. The price range is between 25 and over 300 euros - depending on the equipment.

Numerous different companies have specialized in the production of surface-mounted cisterns or these in their assortment. Leading players include:

  • Duravit
  • Geberit
  • Grohe
  • Keramag
  • Schwab
  • Vereg
  • Villeroy & Boch

Maintenance and cleaning of the flush-mounted cistern

Although surface-mounted cisterns are durable, they can sometimes cause malfunction. In many cases, the cistern licks after a few years - the water runs permanently. Maintenance and cleaning will then be unavoidable.

Compared to flush-mounted models, the maintenance and cleaning of a surface-mounted cistern is usually associated with significantly less effort because the box is freely accessible. With ceramic model, the applied cover only has to be removed, with plastic boxes it is inserted. In addition, the handyman should turn off the angle valve to interrupt the flow of water. This is usually located directly next to the box.

Afterwards, the individual parts of the cistern can be removed. This is best placed in a bowl of detergent overnight. As Kalklöser offer Essigessenz and citric acid from the home remedy department. But also purchased products can be used. These should also be added to the water in the cistern. After some soaking time, the items and the cistern itself can be cleaned with a wire brush, rinsed and everything can be used again. Repeated rinsing stops cleaning.

On this occasion, the seals should be checked. If they are hard and porous, do-it-yourselfers should replace them.

Replacing a surface-mounted cistern

Replacing a surface-mounted cistern is usually much easier than with flush-mounted models. The craftsman only needs the following tools:

  • Water pump pliers
  • Open-end wrench
  • Screwdriver
  • Saw
  • Impact Drill

In the first step, as in the case of maintenance, the water supply is stopped before the old cistern is dismantled can. Thereafter, the connecting pipes can be removed. A surface-mounted cistern usually only has to be lifted out of the wall bracket so that it can be pulled off.

In the second step, the new surface-mounted cistern is assembled in accordance with the manufacturer's installation instructions. In many cases, the old wall brackets can be reused, rarely need new brackets in the wall. After installation, the drainpipe can be measured, cut to size and attached. Thereafter, all that remains to be done is to connect the water supply - this often happens in newer models via a flexible hose to the angle valve of the surface-mounted cistern.

Once all connections have been made, the do-it-yourselfer can open the valve, adjust the float for the appropriate or desired amount of water and the installation is complete.


Surface-mounted cisterns are fixed in front of the wall as opposed to flush-mounted cisterns therefore optically visible in the bathroom. This is a disadvantage especially in small wet cells. However, they can be maintained and cleaned with significantly less effort. In addition, there are surface-mounted cisterns in different materials, colors and shapes, so that a model can be found to suit every bathroom.
