A urine collector (1) and a method for mounting the urine collector to a toilet bowl. The collector is made of paper sheet and comprises a central collection area (20), a front flap (4), a rear part (23), two side wings (3 A, 3B) each extending from the central collection area (20) and further two rear wings (2 A, 2B) extending from the rear part (23). Each of the wings (2 A, 2B, 3 A, 3B) and the front flap (4) are provided with sticky material (6) for fastening them to the toilet bowl (5). The urine collector (1) is mounted onto a toilet bowl (5) by fastening the front flap (4) to the front part of the bowl opening (5C), and fastening the wings (2A, 2B, 3A, 3B) to the edge of the toilet bowl opening (5). After urine collection in the collection area (20), the front flap is detached from the front of the toilet bowl and lifted, while the side wings and rear wings are still attached. This causes the collected urine to flow over the rear part into a separate sampling container.
