Abstract: A collapsible bath brush is disclosed with a handle that collapses telescopically into the interior of the brush head, thereby making the brush more convenient, compact, and adaptable than other bath brushes. In preferred embodiments, the brush head includes bristles or a sponge, the handle includes at least three segments, and when extended, the handle is wide (at least one inch), long, and easy to hold. When the handle is collapsed, the brush head is a fully functional handle-free bath brush without protrusions that could interfere with washing. A securing mechanism prevents inadvertent collapse of the handle when extended, and in preferred embodiments a retaining mechanism prevents inadvertent extension of the handle when collapsed. The brush is easy to pack for travel, requiring no disassembly to achieve its smallest configuration. In preferred embodiments the brush has an open, horseshoe-shaped, easy-to-clean handle, and can be disassembled for thorough cleaning.
