1. A floor panel for installation over a subfloor, comprising: a core layer comprising a first thermoplastic material;a surface layer disposed over the core layer, wherein the surface layer comprises a second thermoplastic material;two pairs of opposing side edges defining first, second, third, and fourth side edges, wherein each of the side edges comprises coupling portions, wherein a first coupling portion of the first side edge comprises a groove and a second coupling portion of the second side edge comprises a tongue; wherein the tongue and the groove comprise a third thermoplastic material,wherein the tongue and groove are configured to join to an opposing groove and an opposing tongue, respectively, of adjacent panels, wherein the tongue and the groove are configured to lock with the opposing groove and opposing tongue, respectively, so as to prevent separation of the joined panels in a vertical as well as a horizontal direction;wherein the groove comprises a lower lip portion that extends further in length than an upper portion of the groove;wherein the surface layer is disposed over the core layer without extending over the tongue in a configuration prior to the tongue joining an adjacent panel; andwherein the panel is configured to be installed over a subfloor. 2. The floor panel according to claim 1, wherein the tongue and the groove are configured to click together. 3. The floor panel according to claim 1, wherein the tongue and the groove are configured to lock together as to prevent separation perpendicular to a plane of at least one edge of the panel. 4. The floor panel according to claim 1, wherein the thermoplastic material of the surface layer is polyvinyl chloride (PVC). 5. The floor panel according to claim 1, wherein a portion of the groove comprises at least one recess configured to engage a portion of the opposing tongue. 6. The floor panel according to claim 5, wherein the groove comprises a vertical plane corresponding to an outermost edge of the upper groove portion. 7. The floor panel according to claim 6, wherein the lower groove portion comprises at least one recess configured to engage a portion of the opposing tongue. 8. The floor panel according to claim 7, wherein at least a portion of the at least one recess extends beyond the vertical plane. 9. The floor panel according to claim 8, wherein the entire recess is positioned beyond the vertical plane. 10. The floor panel according to claim 1, wherein a portion of the tongue comprises at least one web configured to engage a portion of the opposing groove. 11. The floor panel according to claim 1, wherein the surface layer comprises a layer of plastic having a decorative design. 12. The floor panel according to claim 1, wherein two or all three of the thermoplastic materials are the same or different. 13. The floor panel according to claim 1, wherein the core layer constitutes a base material for the floor panel and wherein the tongue and groove are formed integrally with the base material, the first and third thermoplastic materials being the same thermoplastic material. 14. The floor panel according to claim 1, wherein both pairs of side edges comprise coupling portions configured to lock with an opposed edge to prevent separation of the joined panels in a vertical as well as a horizontal direction. 15. A floor panel for installation over a subfloor, the floor panel comprising: a core layer comprising a third thermoplastic material;a surface layer disposed over the core layer, wherein the surface layer comprises a second thermoplastic material; andtwo pairs of opposing side edges defining first, second, third, and fourth side edges, wherein each of the side edges comprises coupling portions, wherein a first coupling portion of the first side edge comprises a groove and a second coupling portion of the second side edge comprises a tongue; wherein the tongue and the groove comprise a third thermoplastic material,wherein the tongue and groove are configured to join with an opposing groove and an opposing tongue, respectively, of adjacent panels, wherein the tongue and the groove are configured to lock with the opposing groove and opposing tongue, respectively, so as to prevent separation of the joined panels in a vertical as well as a horizontal direction;wherein the groove comprises a lower lip portion that extends further in length than an upper portion of the groove;wherein the surface layer is configured to abut against a surface layer of a joined panel when the tongue and groove of adjacent panels cooperate; andwherein the panel is configured to be installed over a subfloor. 16. The floor panel according to claim 15, wherein two or all of the thermoplastic materials are the same or different. 17. The floor panel according to claim 15, wherein the core layer constitute a base material for the floor panel and wherein the tongue and groove are formed integrally with the base material, the first and third thermoplastic materials thereby being the same thermoplastic material. 18. The floor panel according to claim 15, wherein both pairs of opposing side edges comprise coupling portions configured to lock with an opposed edge to prevent separation of the joined panels in a vertical as well as a horizontal direction.
