  We calculate the $B\Bbar$ mixing in the Randall-Sundrum bulk model. In this
model, all the Standard Model fields except the Higgs can reside in the bulk.
Two suggestive models of "mixed" and "relaxed" scenarios are considered. We
find that the enhancement of the loop function is 0.51% for the "relaxed" and
1.07% for the "mixed" scenario when the first 4th KK modes are included, for a
bulk fermion mass parameter $\nu=-0.3$.
