  This paper discusses the configuration of gravitational vacuum star or
gravastar with the impact of geometry and matter coupling present in $f(R,T)$
gravity. The gravastar is also conceptualized as a substitute for a black hole
which is illustrated by three geometries known as (1) the interior geometry,
(2) the intermediate thin-shell and (3) the exterior geometry. For a particular
$f(R,T)$ model, we analyze these geometries corresponding to Kuchowicz metric
function. We evaluate another metric potential for the interior domain as well
as the intermediate shell which is non-singular for both domains. The
Schwarzschild metric is adopted to demonstrate the exterior geometry of
gravastar, while the numerical values of unknown constants are calculated
through boundary conditions. Finally, we discuss different features of
gravastar regions like proper length, energy, surface redshift as well as
equation of state parameter. We conclude that the gravastar model can be
regarded as a successful replacement of the black hole in the context of this
gravity.
