[Study the connection between the masing disk and obscuring torus in Seyfert 2 galaxies. ]{} [We present a uniform X-ray spectral analysis of the high energy properties of 14 nearby megamaser Active Galactic Nuclei observed by *NuSTAR*. We use a simple analytical model to localize the maser disk and understand its connection with the torus by combining *NuSTAR* spectral parameters with available physical quantities from VLBI mapping.]{} [Most of the sources analyzed are heavily obscured, showing a column density in excess of $\sim$ 10$^{23}$ cm$^{-2}$. In particular, 79% are Compton-thick ($N_{\rm H}$ &gt; 1.5 $\times$ 10$^{24}$ cm$^{-2}$). Using column densities measured by *NuSTAR*, with the assumption that the torus is the extension of the maser disk, and further assuming a reasonable density profile, the torus dimensions can be predicted. They are found to be consistent with mid-IR interferometry parsec-scale observations of Circinus and
