A shower column assembly includes a shower rail and a quick-connect system. The quick-connect system includes an arm attachment, an intermediate fitting, and a collar. A first end of the arm attachment is mountable to a fluid conduit. At least a portion of the arm attachment at a second end of the arm attachment is sized to be received within the intermediate fitting and the collar. The collar is configured to slidably engage with the intermediate fitting and press against the intermediate fitting to deform the intermediate fitting over the second end of the arm attachment.
