A flotation tank (1) comprises a self-supporting tank (2). The tank (2) is made of thermoplastic polymer. The tank (2) has a lower tank part (3) and a tapered upper tank part (4) which is narrower than the lower tank part (3). The tank (2) has a mouth (5) at the upper end of the upper tank part (4) and an overflow lip (6) at the periphery of the mouth (5). The flotation tank (1) further comprises an overflow receptacle (7). The overflow receptacle (7) is made of thermoplastic polymer and connected to the tapered upper part (4) of the tank (2) beside the overflow lip (6) for receiving, collecting and discharging an overflow that overflows from the tank (2) over the overflow lip (6), when in use.
