The invention provides a tanning tub which can be inflated for use and deflated for transporting and for storage. Two tubular walls vertically stacked support a tubular air mattress attached suspended centrally between the walls. The tubes in the tubular mattress have clear plastic upper surfaces and the opposite tube sides are fabricated of silvery colored material. The tubular walls and the tubular mattress when inflated form into a water proof container which can be used by a sunbather to relax in a cool pool of water. The clear top and silvery bottom arrangement of the mattress tubes allows a sunbather to tan on both sides at the same time, one side by direct exposure and the other side by reflection. The inflated tanning tub can be used as a float in a pool, for tanning dry on land, and as a bed for camping or a spare bed at home.
