Step 16

The next step is to place the outer socket of the steam shower. We apply mounting adhesive on the back of the piece and fix it in its position.

Finally, we put the heating device in its support and put the stones and check that the steam shower works properly. We wait until it reaches the ideal temperature, approximately 90º and we add the aromatic essences. The product should be diluted with water. To avoid possible mishaps, be careful not to leave anything on the stones of the heater, even if you are not using the steam shower.
