The wall portion defines a cover-facing surface arranged to interface with the drain cover, and a tile-facing surface arranged to face one or more tiles surrounding the support frame. One or more material locking features are on the tile facing surface to help retain grout between the support frame and the surrounding tiles. During installation of the support frame in the tile floor, the vertical position of the support frame over the drain opening is adjustable and the support frame does not extend downwardly into the drain opening such that the support frame is floatable over the drain opening for lateral and rotational adjustment of the support frame relative to the drain opening. ## Claims ### Claim 1 A drain system comprising: a support frame configured to support and position a drain cover over a drain opening in a tile floor, the support frame including: a base portion; a wall portion projecting upwardly from the base portion to define a seat for the drain cover within the support frame, the wall portion defining a cover-facing surface arranged to interface with the drain cover, and a tile-facing surface arranged to face one or more tiles surrounding the support frame; and one or more material locking features on the tile-facing surface configured to enhance retention of grout applied between the support frame and the one or more tiles surrounding the support frame, the one or more material locking features defining a plurality of openings such that when the grout is applied to the tile-facing surface the grout penetrates and forms a mechanical or micromechanical lock with the one or more material locking features, wherein during an installation of the support frame in the tile floor a vertical position of the support frame over the drain opening is adjustable and the support frame does not extend downwardly into the drain opening such that the support frame is floatable over the drain opening for lateral and rotational adjustment of the support frame relative to the drain opening. ### Claim 2 (depends on 1) The drain system of claim 1, wherein the vertical position of the support frame over the drain opening is adjustable via a plurality of set screws threadedly attached to the base portion. ### Claim 3 (depends on 1) The drain system of claim 1, wherein an angle of the support frame over the drain opening is adjustable relative to the drain opening. ### Claim 4 (depends on 1) The drain system of claim 1, wherein the one or more material locking features comprises at least one fabric layer molded on the tile-facing surface. ### Claim 5 (depends on 4) The drain system of claim 4, wherein the at least one fabric layer comprises a polyester material having a non-woven construction. ### Claim 6 (depends on 4) The drain system of claim 4, wherein the at least one fabric layer comprises a Polyethylene material. ### Claim 7 (depends on 4) The drain system of claim 4, wherein the at least one fabric layer includes a tileable flap that is movable or foldable relative to a connection between the tileable flap and a bottom of the wall portion or a bottom of the support frame. ### Claim 8 (depends on 7) The drain system of claim 7, wherein the tileable flap is configured to extend below at least a portion of the one or more tiles surrounding the support frame and a substrate attached to the one or more tiles surrounding the support frame. ### Claim 9 (depends on 1) The drain system of claim 1, wherein the drain cover comprises a temporary construction plug having a solid configuration positionable in the support frame during a tile installation project and defining a plurality of access holes corresponding to a plurality of set screws in the support frame such that at least one of the vertical position and an angle of the support frame relative to the drain opening is adjustable with the construction plug positioned in the support frame. ### Claim 10 (depends on 9) The drain system of claim 9, wherein the temporary construction plug is interchangeable with a drain grate having a perforated configuration. ### Claim 11 (depends on 1) The drain system of claim 1, wherein the drain cover comprises a temporary construction plug having a solid configuration positionable in the support frame during a tile installation project. ### Claim 12 (depends on 11) The drain system of claim 11, wherein the temporary construction plug is arranged to form a reversible snap-fit within the support frame when the temporary construction plug is positioned in the support frame. ### Claim 13 (depends on 12) The drain system of claim 12, wherein a height and an angle of the support frame over the drain opening is adjustable via a plurality of set screws threadedly attached to the temporary construction plug. ### Claim 14 (depends on 13) The drain system of claim 13, wherein the set screws are located at least in part radially inside of the base portion of the support frame. ### Claim 15 A drain system comprising: a drain cover comprising a construction plug; a support frame configured to support and position the construction plug over a drain opening in a tile floor, the support frame including a base portion and a wall portion projecting upwardly from the base portion to define a seat for the construction plug within the support frame, wherein during an installation of the support frame in the tile floor a vertical position of the support frame over the drain opening is adjustable and the support frame does not extend downwardly into the drain opening such that the support frame is floatable over the drain opening for lateral and rotational adjustment of the support frame relative to the drain opening; one or more material locking features on a tile-facing surface of the wall portion configured to enhance retention of grout applied between the support frame and the one or more tiles surrounding the support frame, the one or more material locking features defining a plurality of openings such that when the grout is applied to the tile-facing surface the grout penetrates and forms a mechanical or micromechanical lock with the one or more material locking features; and a locking system arranged to selectively and temporarily lock the construction plug and the support frame together during installation of the tile floor. ### Claim 16 (depends on 15) The drain system of claim 15, wherein the locking system is configured to adjust at least one of an angle and the vertical position of the support frame relative to the drain opening during installation of the tile floor. ### Claim 17 (depends on 15) The drain system of claim 15, wherein the locking system comprises a threaded connection between the support frame and a plurality of set screws including lower ends engaging with an upper surface of a drain fixture defining the drain opening. ### Claim 18 (depends on 17) The drain system of claim 17, wherein the lower ends of the plurality of set screws are unattached to the upper surface of the drain fixture. ### Claim 19 A drain system comprising: a drain fixture defining a drain opening; a construction plug; a support frame configured to support and position the construction plug over the drain opening on the drain fixture, the support frame including a base portion and a wall portion projecting upwardly from the base portion to define a seat for the construction plug within the support frame, wherein during an installation of the support frame in the tile floor a vertical position of the support frame over the drain opening is adjustable and the support frame does not extend downwardly into the drain opening such that the support frame is floatable over the drain opening for lateral and rotational adjustment of the support frame relative to the drain opening; one or more material locking features on a tile-facing surface of the wall portion configured to enhance retention of grout applied between the support frame and the one or more tiles surrounding the support frame, the one or more material locking features defining a plurality of openings such that when the grout is applied to the tile-facing surface the grout penetrates and forms a mechanical or micromechanical lock with the one or more material locking features; and a locking system arranged to selectively and temporarily lock the construction plug and the support frame together during installation of a tile floor surrounding the drain opening.
