**Summary:**For a class of Hilbert spaces ${\H}$ of functions analytic on a domain $D\subset \C^n$, we characterize the $n$-tuples $T$ of commuting Hilbert space operators which can be represented by means of multiplications by the coordinate functions on ${\H}$. In~case $\H$ is a subspace of some $L^2$-space we thus obtain for such $T$ a normal dilation constructed in terms of the reproducing kernel of ${\H}$. This generalizes known results of this type and provides new models in a large class of functional Hilbert spaces, including the standard weighted Bergman spaces of analytic functions on bounded symmetric domains.
