The present invention is directed to a portable spa comprising a shell having a plurality of seats and an arrangement of water jet assemblies. At least one overlay panel is removably secured to a portion of the shell by the jet assemblies, wherein the jet assemblies extend through both the overlay panel and the shell. In one embodiment, the overlay panel is secured to an upper portion of a seat. The upper portion of the seat has a receiver that is recessed from the outer surface of the seat and cooperatively dimensioned with the overlay panel. The jet assembly comprises a stem that extends through a shell opening and a panel opening. Each jet assembly includes a sealing element that engages the panel and the shell to seal the shell opening. The jet assembly also includes a securing element that provides a clamping force to secure the overlay panel against the shell. In an installed position, the overlay panel is secured against the receiver and the seat by at least one jet assembly that extends through both the panel and the shell.
