A stopper of a bathroom sink or tub includes a shank removably connected to a base part which is connected to the sink or tub and has a drain hole. A cap is connected to the shank and has a flange that extends radially from the cap. A connection portion is formed on the underside of the flange. A seal part is connected to the connection portion and includes a support ring and a collar. The support ring has at least one hook member formed in the inner periphery thereof so as to be connected to the connection portion of the cap. A positioning portion extends from radially from the support ring. The collar is a rubber collar and has a groove in the inner periphery thereof. The positioning portion of the support ring is engaged with the groove to prevent the collar from deformation and generating noise.
