Abstract: Hydration devices are disclosed, which overcome the drawbacks inherent to conventionally sunbathing in the absence of a nearby body of water. A hydration device includes a seat or lounger, two side panels, and a water port. The seat and the side panels are configured to retain water, at least up to a water level. The water port may be adapted to accept water to fill the hydration device, and may be disposed on the seat. Another hydration device includes a seat, a water port, a support structure, and a water impervious layer. The support structure includes two lateral bars disposed substantially parallel to each other and joined by two horizontal bars. The seat is disposed on the water impervious layer, which is disposed over the support structure. The water port is disposed on the seat and is configured to accept water to fill a fillable portion.
