Drain system for use with a tile floor

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.
