Inflatable pool

Abstract

The present invention includes an inflatable spa pool with thermal insulative properties to maintain an elevated temperature of water stored in the spa pool. The inflatable spa pool can include a pool body including a wall and a bottom, where the wall includes an inner wall and an outer wall, where the inner wall and the bottom define a cavity with a first upper opening. The inflatable spa pool can include a thermal insulation pool sheath with a second upper opening to receive the pool body, where the thermal insulation pool sheath includes an outer sheath and a first thermal insulation structure. The inflatable spa pool can include a thermal insulation pool lid that includes an outer lid and a second thermal insulation structure, where the bottom includes an upper layer and a lower layer for receiving a third thermal insulation structure.
