A tub assembly for a washing machine appliance includes a tub and a wash basket rotatably mounted within the tub. The tub defines a central axis extending along an axial direction, a radial direction perpendicular to the central axis, and a circumferential direction extending around the central axis. The tub comprises a first material. The wash basket defines a wash chamber for receiving articles for washing. A reinforcement band encircles the tub generally along the circumferential direction. The reinforcement band comprises a second material having a greater strength than the first material of the tub.
