The linear drain assembly includes a base portion and a first peripheral portion. The base portion includes a base trough and a base flange. The first peripheral portion includes a first trough and a first flange. The first trough is nested within the base trough and the base flange is nested within the first flange. ## Claims ### Claim 1 A linear drain assembly comprising: a base portion comprising a base trough and a base flange; and a first peripheral portion comprising a first trough and a first flange; wherein the first trough is nested within the base trough and the base flange is nested within the first flange; and wherein the first peripheral portion is slidable along the base portion when the first trough is nested within the base trough. ### Claim 2 (depends on 1) The linear drain assembly of claim 1, wherein the base portion further includes an outlet body extending away from the base portion and in fluid communication with both the base trough and the first trough. ### Claim 3 (depends on 1) The linear drain assembly of claim 1, further comprising a second peripheral portion comprising a second trough and a second flange, the second trough configured for nesting within the base trough and second flange configured to receive the base flange, the second peripheral portion slidable along the base portion independently of the first peripheral portion when the second trough is nested within the base trough. ### Claim 4 (depends on 3) The linear drain assembly of claim 3, wherein all of the base portion, the first peripheral portion, and the second peripheral portion are formed of stainless steel. ### Claim 5 (depends on 1) The linear drain assembly of claim 1, wherein the first peripheral portion further includes a first ledge extending away from the first flange, the first ledge and the first flange cooperating to define a first flange cavity that receives the base flange. ### Claim 6 (depends on 5) The linear drain assembly of claim 5, wherein the first ledge comprises a first aperture extending through the first ledge and configured to receive a fastener. ### Claim 7 (depends on 6) The linear drain assembly of claim 6, further comprising a threaded fixture configured to receive the fastener. ### Claim 8 (depends on 1) The linear drain assembly of claim 1, further comprising a drain grate positionable within both the base trough and the first trough, the drain grate comprising a grate surface facing out of the base trough and the first trough, the grate surface profiled with a plurality of grate apertures configured to allow a flow of water through the grate surface. ### Claim 9 (depends on 8) The linear drain assembly of claim 8, wherein the drain grate further comprises adjustable legs, the adjustable legs threadedingly coupled with the drain grate and configured to engage one of the base portion and the first peripheral portion. ### Claim 10 A linear drain assembly comprising: a base portion comprising: a first base end; a second base end; a base trough extending between the first base end and the second base end; an outlet body in fluid communication with the base trough and extending away from the base portion in a first direction; and a base flange extending away from the base portion, the base flange defining a base flange width; and a first peripheral portion comprising: a first peripheral end; a second peripheral end; a first wall, a second wall, and a third wall defining a first trough; and a first flange extending away from the first trough and defining a first flange width, the first flange width greater than the base flange width; wherein the first peripheral portion is slidable along the base portion when the first trough is nested within the base trough. ### Claim 11 (depends on 10) The linear drain assembly of claim 10, wherein the first peripheral portion is slidable relative to the base portion when the first flange abuts the base flange. ### Claim 12 (depends on 10) The linear drain assembly of claim 10, further comprising a leg assembly rotatably coupled with the first peripheral portion proximate to the first peripheral end, the leg assembly configured to adjust a distance between the first peripheral end and a surface upon which the leg assembly rests. ### Claim 13 (depends on 12) The linear drain assembly of claim 12, wherein the leg assembly is coupled with both the first wall and the second wall. ### Claim 14 A method of assembling a linear drain assembly, the method comprising: positioning a first peripheral portion within a base portion; sliding the first peripheral portion within the base portion to a desired position; coupling the first peripheral portion to the base portion; cutting a drain grate to fit within the first peripheral portion and the base portion; and positioning the drain grate within both the first peripheral portion and the base portion. ### Claim 15 (depends on 14) The method of claim 14, further comprising: positioning a second peripheral portion within the base portion; sliding the second peripheral portion within the base portion to a desired position; coupling the second peripheral portion to the base portion; and positioning the drain grate within all of the first peripheral portion, the second peripheral portion, and the base portion. ### Claim 16 (depends on 15) The method of claim 15, further comprising: forming a first watertight seal between the first peripheral portion and the base portion; and forming a second watertight seal between the second peripheral portion and the base portion such that the first peripheral portion, the second peripheral portion, and the base portion cooperate to form a single watertight trough. ### Claim 17 (depends on 16) The method of claim 16, wherein the step of forming the first watertight seal between the first peripheral portion and the base portion comprises: disposing a liquid sealant on at least one of the base portion and the first peripheral portion; and positioning the first peripheral portion within the base portion to squeeze the liquid sealant between the first peripheral portion and the base portion and form the first watertight seal. ### Claim 18 (depends on 14) The method of claim 14, wherein: the first peripheral portion includes a first flange and a first ledge cooperating to define a first cavity, the first ledge having a first aperture configured to receive a fastener; and the base portion includes a base flange configured to be received within the first cavity; the method further comprising: positioning the base flange within the first cavity; threading a fastener through the first aperture and engaging the base portion with the fastener to couple the first peripheral portion with the base portion. ### Claim 19 (depends on 14) The method of claim 14, wherein the drain grate includes adjustable feet that engage with one of the base portion and the first peripheral portion, the method further comprising: extending a tool through the drain grate to engage the adjustable feet to adjust the height of the drain grate relative to the base portion.
