The pool is integrally formed, resulting in a unitary pool shell having a floor, one or more sidewalls connected to the floor, a surface, such as a step or bench, extending from at least one of the sidewalls; and a peripheral wall extending from the surface to the floor. ## Claims ### Claim 1 A pool comprising: a floor; one or more sidewalls connected to the floor; a surface extending from at least one of the sidewalls; and a peripheral wall extending from the surface to the floor, wherein the floor, sidewalls, peripheral wall and surface are integrally formed. ### Claim 2 (depends on 1) The pool of claim 1, wherein the joins between at least the walls and sidewalls are reinforced with a chamfered or angled portion. ### Claim 3 (depends on 1) The pool of claim 1, wherein the surface extends substantially perpendicularly from the sidewall and the peripheral wall extends substantially perpendicularly from the surface. ### Claim 4 (depends on 3) The pool of claim 3, wherein, in use, the surface is substantially horizontal and the peripheral wall is substantially vertical. ### Claim 5 (depends on 4) The pool of claim 4 wherein the surface is in the form of a seat, bench, or step. ### Claim 6 (depends on 1) The pool of claim 1, wherein the pool is formed from a cementitious material. ### Claim 7 (depends on 1) The pool of claim 1, wherein one or more reinforcing elements are located within one or more of: the floor, sidewalls, peripheral wall and surface. ### Claim 8 (depends on 7) The pool of claim 7, wherein the reinforcing elements comprise reinforcing rods arranged in a mesh configuration to form a reinforcement cage. ### Claim 9 (depends on 8) The pool of claim 8, further comprising one or more attachment points located within at least one of the floor, sidewalls and peripheral wall. ### Claim 10 (depends on 9) The pool of claim 9, wherein the attachment points comprise ferrules. ### Claim 11 (depends on 10) The pool of claim 10, wherein the attachment points are mounted to the reinforcing rods. ### Claim 12 (depends on 1) The pool of claim 1, wherein a second surface is attached or connected to one or more of the sidewalls, the second surface extending substantially perpendicularly from the one or more sidewalls to form a seat, bench, or step. ### Claim 13 (depends on 1) The pool of claim 1, wherein one or more of the sidewalls includes a cut-out section configured to receive a skimmer box. ### Claim 14 (depends on 1) The pool of claim 1, wherein the pool has an internal surface and an external surface, wherein a swimming hollow is defined by the internal surface and a cavity defined by the external surface is formed adjacent the peripheral wall and the surface. ### Claim 15 (depends on 1) The pool of claim 1, wherein the floor, sidewalls, surface, and/or peripheral wall have a thickness of between approximately 80 mm to 120 mm. ### Claim 16 (depends on 15) The pool of claim 15, wherein the floor, sidewalls, surface, and peripheral wall have substantially the same thickness. ### Claim 17 A method of forming a plunge pool the method comprising the steps of: forming an integral plunge pool shell having at least one step or seat feature in a mould; extracting the plunge pool shell from the mould; and finishing an internal surface of the plunge pool to be waterproof. ### Claim 18 (depends on 17) The method of claim 17, wherein the step of finishing the internal surface of the plunge pool comprises treating the surface with a thermo-polymer. ### Claim 19 (depends on 17) A method of installing a plunge pool comprising the steps of: forming a plunge pool as claimed in claim 17; transporting the plunge pool to a desired location; and installing the plunge pool shell at the desired location. ### Claim 20 (depends on 19) The method of claim 19, wherein the step of installing the plunge pool shell at the desired location comprises lifting the plunge pool using ferrules located in a floor of the plunge pool shell.
