Backrooms Poolrooms: Pool Complex and Flooded Tile Halls

A complete tiled swimming complex and the flooded halls behind it. An L shaped pool with its lap lane and steps, a cantilevered sun deck carried by a single mushroom column, a vast hall where dozens of tiled pillars stand in ankle deep water, and a receding arcade of square portals that fades into the distance. Everything is white and pale grey square ceramic tile, walls, floors and ceilings alike, broken only by turquoise water and thin black steel handrails. No sun, no sky, only cool fluorescent light and reflections on wet tile.

  • Five connected zones: main pool hall, flooded pillar hall, portal arcade, upper balcony walkway, and a ramp descending into deep water

Important notes
