Is it possible to install a heating mat in the shower?


Installation of a heating mat (under tiles) in the shower in the shower area is a question constantly asked by many people. In many forums or blogs you can see endless statements for and against.

Let’s start with the fact that the shower belongs to the “0” zone, which means: Zone “0” is the interior of the bathtub or shower pool. Equipment and fixtures installed there should have a degree of protection of not less than IPX7.

The formula tells us only about the interior of the shower, but what if the heating mat is in the floor structure, stuck in the adhesive under the tiles, does this layer belong to zone “0”? Here we do not have strict regulations, but reasoning logically it is not the interior.

  • Installed in a layer of cement-based mortar, the mat is permanently protected from mechanical damage.
  • Installation must be carried out only by a person authorized to do so, such as an electrician with SEP electrical license or PRO RAYCHEM installer.
  • Before commissioning the installation, three measurements must be taken: insulation resistance at 1000 volts, which assures us that its insulation is not damaged: before laying the mat, after laying the mat on the floor, after sealing with glue and tiles. The same applies to continuity measurements of the resistance of the heating cable. All the results of the measurements must be entered in the installation acceptance protocol.
  • The installation according to building standards must absolutely be protected with a residual current and overcurrent circuit breaker.
