We report the existence of explicit flux configurations leading to stable de Sitter and Anti- de Sitter vacua, consisting on Type IIB compactifications on a 6-dimensional anisotropic torus threaded with standard and S-dual invariant non-geometric fluxes in the presence of orientifold 3-planes. In all dS vacua the masses of the complex structure moduli are heavier than the Hubble scale suggesting that the axio-dilaton and K\"ahler moduli are natural candidates for small-field inflation. We also find that, at least for the reported solutions, compactifications on anisotropic torus increases the number of moduli fields with sub-Hubble masses with respect to a compactification on an isotropic torus.
