allowing the covering frame to be supported on the positioning aid by means of the aid height adjustment means, setting the height of the covering frame;

wherein the method comprises the further step of:

after the adhesive has set, subsequently removing the positioning aid, so that the covering frame suspends from the tiles.

17. The method according to claim 16 , wherein the positioning aid is for one time use; and

wherein the step of removing the positioning aid is a destructive step.

20. The drain according to claim 1 , wherein the grating support comprises:

a lower body; and

a flange part above the lower body, the flange part being wider than the lower body;

wherein the flange part is configured for resting on opposite steps of the standing side walls of the collecting container; and

wherein the lower body has a width matching a horizontal distance between corresponding two opposite side walls of the collecting container.

21. The drain according to claim 20 , wherein the grating support has multiple rotation positions within the collecting container, each of the rotation positions corresponding to a different height position of the grating; and

wherein the lower body, in each of the rotation positions, has a width matching the horizontal distance between the corresponding two opposite side walls of the collecting container.

22. The drain according to claim 21 , wherein the grating has a downward extending coupling strip;

wherein the grating support further comprises coupling grooves for receiving the downward extending coupling strip;

wherein each coupling groove corresponds to a respective one of the rotation positions;

wherein each coupling groove has a groove depth; and

wherein each groove depth is different one from another.

23. The drain according to claim 22 , wherein the downward extending coupling strip fits clampedly in the respective coupling groove.
