  Given a simple connected compact Lie group $K$ and a maximal torus $T$ of
$K$, the Weyl group $W=N_K(T)/T$ naturally acts on $T$. First, we use the
combinatorics of the (extended) affine Weyl group to provide an explicit
$W$-equivariant triangulation of $T$. We describe the associated $W$-dg-ring.
For a non-crystallographic Coxeter group, using compact hyperbolic extensions
rather than affine ones, we construct a compact $W$-manifold $\mathbf{T}(W)$,
which is an analogue of a torus for $W$. We exhibit a $W$-equivariant
triangulation of $\mathbf{T}(W)$ and compute the associated $W$-dg-ring. Also,
we derive its homology representation.
