A cooler (100) for supplying cooled drinking water, particularly at remote outdoor locations, includes a reservoir (101) that supplies water to a conduit (119) for indirect cooling by a cooling medium, for example ice, contained in a container (105). A water bottle (103) is installed in the cooler (100) such that a feed tube (111) of the reservoir (101) penetrates and engages the hygienic seal (201) of the water bottle (103). The conduit (119) is connected to a discharge (113) on the reservoir (101) and a spigot (125). When the spigot (125) is opened, water passes through the conduit (119) and is indirectly cooled.
