  In this paper, we explore the characteristics of a gravastar in
$f(\mathcal{Q})$ gravity, which is upheld by Krori-Barua (KB) metric. We have
used Krori-Barua (KB) metric for the interior and shell regions of the
gravastar. We deduced our field equations by using Krori-Barua metric. In the
outside regions of the gravastar, we have taken two regular black hole metrics.
Additionally, we have applied the Israel junction condition to calculate the
potential difference across the thin shell concerning different types of
regular black holes, such as Bardeen and Hayward. We have also discussed the
physical properties like proper length, entropy, energy, EoS and stability.
