A swivel handle structure for a bathtub includes a holder, a handle seat and a press ring. The holder comprises a connecting plate having a number of locating holes and a recess thereon. The handle seat comprises a rotary disc having a circular rim inwardly corresponding to the recess of the connecting plate. The press ring is sleeved onto the handle seat. The press ring has a block rim to block the handle seat so as to confine the press ring from moving any further. When turning the handle seat, the circular rim of the rotary disc turns within the recess of the connecting plate so that the press ring maintains the handle seat in a steady manner from rocking or shaking.
