A spa cover includes first and second portions that are rotatable along a pivot axis. The first portion has a first length traverse to the pivot axis, and the second portion has a second length extending in the same direction as the first length. The first length is longer than the second length. When the cover is moved from a closed configuration into an open configuration, lower surfaces of the first and second portions, which face the spa tub water when in the closed configuration and can become unsightly, are moved into a position in which they face each other, whereas the upper surface of the second portion faces the users in the tub. A lifter is provided for moving the spa cover between the closed and an open configurations.
