Abstract

An extendable bath chair assembly includes a primary chair and a secondary chair. The primary chair includes a primary seat, four primary legs, a primary backrest, two socket modules, and two armrests. Each of the socket modules includes two sockets. Each of the sockets is connected with one of the primary legs and has an insertion hole. Each of the armrests has two ends each inserted into the insertion hole of one of the sockets. The secondary chair includes a secondary seat, two secondary legs connected with the secondary seat, and two insert pillars connected with the secondary seat. When one of the armrests is detached from one of the socket modules, each of the insert pillars is inserted into the insertion hole of one of the sockets, so that the secondary chair is combined with the primary chair.
