How to drill the hole for concealed cisterns?

This is one of the most difficult cuts to make on site. Whenever possible, cut the flushing cistern from the side, apply the ceramic piece with the corresponding box location mark, and only after the material has dried, cut it using a hand grinder.

This technique minimises the risk of breaking pieces and is the easiest to carry out.

If this is not possible, the cut should be made with a hand grinder fitted with a continuous diamond disc for porcelain stoneware. In cases where the cut is less than 4 cm from the edge of the piece, you may have to perform a waterjet cut.
