Poolcore is the liminal-space aesthetic built around the indoor swimming pool: cavernous natatorium, school leisure centre, hotel pool at 6am, drained of swimmers and full of chlorine haze and still turquoise water. liminals.space takes your own pool photos and rebuilds them into that humid, dreamlike version: wet tile, condensation light, lane ropes, depth markings, and the kind of echo you can almost hear.

What makes poolcore uniquely unsettling
Most liminal spaces work by removing people from a place associated with crowds. The pool does something stranger. Even when full of swimmers it is already halfway between worlds: the light that hits water and bounces in rippling lattices across the ceiling, the muffled underwater acoustics, the chemical smell that soaks into everything. These features exist in no other room. Empty the pool of people and you are left with a place that was already a little otherworldly, now pushed all the way over the edge.
For most people the indoor pool is locked to a very specific window of childhood: early-morning lessons, the changing room lockers that never quite shut, the terror and thrill of the deep end. When that place goes silent in a poolcore image, it stops being a generic spooky room and becomes the specific, embodied memory of being small in a large, loud, humid space, where the noise is gone and only the feeling remains.
The detail that makes poolcore land is the light. Turquoise water reflection on a white tile ceiling, diffused through condensation: it is the most recognisable indoor light in the world, and it belongs to nowhere else. That is what the rebuild emphasises.
What the liminals.space rebuild emphasises for pools
When liminals.space processes your pool photos it pays particular attention to the elements that make the poolcore aesthetic read immediately:
Tile and grout geometry. The grid of ceramic tile (floor, walls, shower block, corridor) is the visual skeleton of every natatorium. The rebuild sharpens and faintly ages these grids without making them look broken; they should feel like they were always this colour.
Water surface and reflections. Still, glassy, unbroken by swimmers. The turquoise cast from the water bleeds upward onto walls and ceiling in the way it does in real empty pools before the lights are fully on.
Condensation haze. The humid atmosphere softens hard edges, especially at depth. Distant lane ropes lose definition. The far end of the pool feels further than it geometrically is.
Depth markings and lane ropes. These functional objects become surreal when no one is using them: numbers on a pool floor seen through still water, plastic floats strung across silence.
Institutional fixtures. Starting blocks, spectator railings, the clock on the wall, the emergency line at the shallow end. Every one of these items is familiar from childhood and out of place without the noise around them.
How to photograph your pool for the best result
You do not need a professional camera and you do not need the pool to be vintage or decayed. Recent photos of a contemporary leisure centre work just as well as a 1980s natatorium; the AI handles the eerie, timeless feeling. What matters is the angle and the emptiness.
Go early or late. Before swim lessons start, or after the last session ends. Staff will sometimes let you in briefly before opening if you explain, or you can photograph from the viewing gallery above.
Shoot along the length of the pool. The shallow-end-to-deep-end view, or the reverse, gives the most depth and lets the lane ropes create converging lines toward the far wall. This is the classic poolcore composition.
Include the ceiling in at least one shot. The reflected water-light on a white or pale-grey ceiling is the single most recognisable feature of the poolcore aesthetic. Even a corner of it changes the mood of the whole image.
Get the changing corridor. The strip-lit tiled corridor between the changing room and the pool deck, with its lockers and wet footprints and that specific floor drain smell: this is an underrated poolcore space that often produces the strongest results.
No people in frame. The transformation works by depopulating a familiar environment. Having swimmers in your source photos creates ambiguities the AI has to work around. Empty shots produce cleaner, eerier results.
Upload at least 4 photos, up to 6. Variety of angles gives the system more to work with across the full room set.

The childhood swim-lesson connection
Poolcore has a demographic specificity that separates it from other liminal aesthetics. The indoor pool is an almost universal childhood experience in many countries: compulsory swim lessons, galas, the particular boredom and anxiety of waiting on the bench while the other lane finishes. It sits at the intersection of safety (learning a survival skill, adult supervision everywhere) and genuine fear (the deep end, the drain, the acoustics of a room that turns every sound enormous).
When that space goes silent in an image, the emotional content is not simply "creepy empty building." It is the specific texture of a childhood anxiety now reframed as nostalgia: the place remembered from a height of about four feet, seen now from an adult distance. That is the emotional register poolcore works in, and it is why the aesthetic stays compelling even to people who have not consciously thought about a swimming pool in twenty years.
Other liminal spaces with the same energy
If the pool resonates, these spaces carry a similar charge: institutional, humid, echo-prone, or simply too large for the single person who is in them:
What is poolcore and why does it feel so unsettling?
Poolcore is the aesthetic of the empty indoor swimming pool (cavernous natatorium, leisure centre, hotel pool) stripped of swimmers. The combination of turquoise water reflection, condensation haze, wet tile geometry, and total silence creates a dreamlike unease. It lands so hard for most people because the indoor pool is a near-universal childhood memory: the smell, the echo, the terror of the deep end. Empty, it becomes a room out of time.
What kind of pool photos work best?
Empty shots with no people in frame, taken from angles that show the water surface, lane ropes or depth markings, and as much of the tiled surround as possible. A shallow-to-deep-end view, a spectator-gallery angle, or a changing-corridor shot all work well. Recent photos of a modern pool are fine; the AI applies the eerie, timeless quality regardless of the pool's age.
