1. A panel suitable for assembling a waterproof floor or wall covering from a plurality of panels, wherein the panel has a substantially planar top surface, and a substantially planar bottom surface,
the panel having a laminated structure of layers which comprises:
a flexible core layer which is substantially composed of a material which is provided with voids in the form of air pockets and hence is relatively low in density, and
a rigid top layer which comprises a support layer that is substantially composed of a material that is virtually devoid of air pockets and hence is relatively high in density,
wherein the core layer has a lower density than the top layer,
wherein a thickness of the core layer is smaller than a thickness of the support layer, in a ratio of 0.5 or less, and
wherein the support layer comprises a thermoplastic material, wherein the material of the support layer is PVC that is virtually free from plasticizer and contains CaCO3 as filler material.
