Abstract: A portable solar tanning spa having a longitudinally extending first half section and a longitudinally extending second half section, each being formed of a light transparent material. The first half section and the second half section are rotatably connected such that the second half section may rotate into a position parallel with the first half section to allow the user to enter and exit as desired. In a preferred embodiment of the present invention, the longitudinally extending first half section and the longitudinally extending second half section are arranged in a vertical position and are pivotally connected to the rim of a back member to allow the first half section and the second half section to swing outwardly into an open position and inwardly into a closed position. In another preferred embodiment of the present invention, the first half section and the second half section form a cylindrical enclosure having an opening for receiving a door to allow the user to enter or exit the spa as desired.
