A showerhead assembly is provided which includes a handheld showerhead removably connected to a stationary showerhead through ball joint connection. The handheld showerhead includes an elongate handle having an upper housing with a cavity, and a front face including one or more nozzles for spraying water. The stationary showerhead has a traditional showerhead construction, with the exception that it further comprises a ball which engages with the handheld showerhead's cavity so as to allow rotatable and secure attachment of the handheld showerhead to the stationary showerhead. The ball may include a preliminary alignment chamber which houses a locking chamber, and the cavity may include a tension pin which engages with both these chambers so as to provide further support for installation of the handheld showerhead to the stationary showerhead. In addition, a spring-button tab mechanism may be utilized for managing the engagement and disengagement of the ball with the cavity.
