  We provide a new regular black hole solution (RBH) in Einstein Gauss-Bonnet
(EGB) gravity with localized sources of matter in the energy--momentum tensor.
We determine the necessary constraints in order for the solution to be regular.
Although we use a specific form for the energy density as a test of proof,
these constraints could serve as a recipe for constructing several new RBH
solutions in EGB gravity with localized sources. Due to that the usual first
law of thermodynamics is not valid for RBH, so we rewrite the first law for
EGB, which leads to correct values of entropy and volume. The size of the
extremal black hole, whose temperature vanishes, becomes smaller for larger
dimensions, whose radius could be of the order of the Planck units, thus the
evaporation would stop once the horizon radius contracts up to a value close to
the Planck length, which could be related with the apparition of quantum
effects. Furthermore, the presence of matter fields in the energy--momentum
tensor induces two phase transitions, where there are two regions of stability.
This differs from the vacuum EGB solution, where the specific heat is always
negative without phase transition as occurs in Schwarzschild black hole.
