Sink mounting assembly and method for assembling a sink mounting assembly

A washbasin installation arrangement (1), comprising a washbasin (2), a first functional unit (3), a second functional unit (4), and a wall element (5) having a front surface,

• wherein the first functional unit (3) is attachable to the wall element (5), and the first functional unit (3) comprises at least one first port (6) for a fluidic connection to at least one supply line (7) for a fluid, a first line (8) extending through the first functional unit (3), and a first connecting element (9) fluidically connected to the first port (6) via the first line (8);
• wherein the second functional unit (4) is connected to the washbasin (2), wherein the second functional unit (4) comprises at least one second port (10) for a faucet (11), a second line (12) extending through the second functional unit (4), and a second connecting element (13) fluidically connected to the second port (10) via the second line (12);
• wherein the washbasin (2) connected to the second functional unit (4) can be pushed onto the first functional unit (3) attached to the wall element (5), wherein the first connecting element (9) and the second connecting element (13) are connected by a sliding to establish a fluidic connection of the second port (10) and the supply line (7);
• and
• wherein the second functional unit (4) connected to the washbasin (2) completely surrounds the first functional until (3) on each exposed surface protruding away from the wall element (5) when the first functional unit (3) is installed on the front surface of the wall element (5).
