A reinforced punch-free arcuate shower curtain rod includes a base, a sleeve, a short tube, an inner tube, an outer tube, and a pressing member. A double-sided adhesive is disposed on a bottom surface of the pressing member. A positioning block is disposed on the pressing member. The base can be maintained in contact with a wall surface by means of the friction force between the PVC gasket and the wall surface and the adhesive force of the double-sided adhesive. In addition, the positioning block of the pressing member is inserted through the base to be pressed against and in contact with a cambered surface of a front end of the sleeve.
