In the case of large appliances such as the dishwasher or refrigerator, it is not recommended to use the sockets due to the depth of the appliances, for example to be placed directly behind it. Again, cables from electrical appliances often don’t go far. We do not recommend connecting multiple sockets in series, to avoid cable fires.

And: for most connections, you have to Recesses be sawn into your kitchen back wall. We tell you what you have to consider with the individual connections:

Fresh water and waste water connections are at different heights behind the kitchen rear wall.  (Photo:

Connections in the kitchen, part 1: water

In the kitchen are basically two water connections required: One for Fresh water, one for that sewage. Both water connections are generally located in the area of ​​the sink base unit, with an additional one for the fresh water Hot water (left) and Cold water (right) can be connected.

Should be for the dishwasher an additional connection on the cold water valve be attached (combination angle valve).

The rule of thumb applies:

  • Connection height for fresh water: Working height minus 30 cm, ie 91 cm working height (on average) minus 30 cm = 61 cm. The connection should be made at this height as seen from the floor.
  • Connection height for waste water: Working height minus 55 cm, e.g. 91 cm – 55 cm = 36 cm.

Connections in the kitchen, part 2: dishwasher

The dishwasher will also in the scullery connected to a Schuko socket (protective contact). That should also no additional devices be connected. The socket must be in the immediate vicinity of the dishwasher, but not directly behind itto allow the device to be fully integrated into the kitchen unit.


Connections in the kitchen, part 3: built-in stove

The stove junction box should not with high or power current be operated, but rather be connected to the stove via three phases of 220 volts. The junction box can be attached in the middle at approximately the following height:

  • Lower edge of the worktop minus 53 cm, e.g. 85 cm – 53 cm = 32 cm from the floor.

Connections in the kitchen, part 4: self-sufficient hob

Today we find the self-sufficient hob in open-plan kitchens with kitchen islands, on which you can cook with a view of the living room. This is where the socket is either in the middle behind the hob cupboard or even hidden in the base cabinet.

The height of the junction box is calculated as follows:

  • Lower edge of the worktop minus 8 cm, e.g. 87 cm – 8 cm = 79 cm from the floor.

Connections in the kitchen, part 5: built-in oven

With the built-in oven the socket in the middle behind it to be placed. A 16 ampere Schuko socket is sufficient. However, it should be noted that an oven with pyrolysis requires a stove connection box, similar to an electric stove.

The ranking is calculated as follows:

  • Base height + dimensions of the pull-outs + 8 cm, e.g. 15 cm base + pull-out 1 at 30 cm + pull-out 2 at 30 cm + 8 cm = 83 cm.

Connections in the kitchen, part 6: Fridge & Freezer

As a rule, the socket is used for a built-in refrigerator above the cabinet planned, the height is calculated as follows:

  • Total height of the cabinet + 5 cm, e.g. 217 cm + 5 cm = 222 cm from the highest point on the floor.

But: who one Combination of refrigerator and freezer If you choose, you have to plan at least one socket for the freezer in the middle of the base area. As a rule, no connection cable for an electrical device is long enough to be plugged in at a height of over 2 meters.
