Salad Fingers currently resides alone in a small wooden shack, located in the Barren Wasteland. It has the number 22 written on the door, a small window with red curtains, and a chimney. The shack on the outside is brown in color, while the walls and floor inside are colored dark olive green. Mr. Branches is standing 21 yards (or 19 meters) away from it (as seen in the episode "Shore Leave").
It consists of, among other things, a bedroom, phone, table, radio, a couch, an oven, and a safety cupboard. The shack appears to be filthy, with paper and trash scattered on the floor beside the bed (as seen in the episode "Letter").
Salad Fingers never strays too far away from his shack (with the exception of the episode "Cage", where he's lured far away from it by a grubby tap).
Notable Areas
Safety Cupboard
Salad Fingers hiding in his Safety Cupboard.
The safety cupboard is the eponymous opening in the wall enclosed with a sliding door and is located in Salad Fingers' house. Salad Fingers feels safe there, occasionally playing inside of it. It is featured in the eighth episode. In the aformentioned episode, Salad Fingers hides in the cupboard from his radio, which omitted hideous sounds after Salad Fingers was unable to find a radio station on it.
In the cupboard, he was playing with his fingers and impersonated "Penny Pigtails", who went to the market. He also found a piece of brown hair there to complete his hair quintette. Later in the episode, he went in there crying after he ate the hair quintette.
Basement
Salad Fingers' basement, as seen in Episode 11.
The basement in Salad Fingers' house is a small room connected to the rest of the house by a stairway. The room is completely empty except for a desk and a lamp above it.
As seen in one of the episodes, this desk contains Harry’s nametag, a breathing pump from Episode 9, a bone, and a box of flesh that is theorized to have also come from Harry. This flesh is used later in the episode in order to create the new and improved Hubert Cumberdale.
Bedroom
Salad Fingers Bedroom, as seen in Episode 11.
Salad Fingers' bedroom consists of a mattress, a desk, a vanity table, and an unknown painting.
This room is one of the most important locations in Episode 11, as it's here that the first and most of the interactions with the Glass Family happen. In the episode, Salad Fingers can be seen organizing various clothes that have been piled onto the mattress meant for Hubert Cumberdale after transforming him into a "flesh boy".
