Tommy's Bedroom is the main location and head spot in the series.
The room has blue walls with some posters. A poster of the Human Fist, a race car and a drawing made by Tommy of Robotboy are always seen. A red/orange carpet lies on the floor.
He has a white bed with a wardrobe and a writing desk attached to it. Also a orange television and a yellow bean bag are often seen in his room. Tommy is a huge fan of toys and special collectors items. So everywhere there are toys and superhero or robot related stuff standing on shelves. He also has a interest science. A pair of spaceships who hangs at his ceiling and posters on the wall from space makes that clear.
For the rest it's a typical boy's room and so a little bit messy. There are always stuff like DVD's, CD's, clothing, magazines and food on the floor.
- In some episodes the location of the bedroom door changes. In most episodes it is opposite to the window and in some it is opposite to Tommy's bed.
- Also in some episodes the carpet is purplish or blue and pink instead of orange/red. This is also the case with the beanbag in Tommy's Room who changes colors from yellow and orange from time to time.
- In the episode I Hero! the poster of The Human Fist above Tommy's bed is missing and replaced with a poster (of the same size) of Tommy himself with a spacesuit in space. In fact this image on the poster is a screenshot from the episode Grow-No-Mo!.
- The shelfs above Tommy's bed have several items and toys on them. In some episodes there are a change of items. Sometimes it's random toys, teddy-bears and robots. Other times just robots. In the episode Remote Out of Control there is one picture in a frame on the top shelf with just a picture of Tommy in it. In most episodes of series 2 (Seasons 3 and 4) there is a doll-head on the top shelf from a man that holds headphones. It's a item that didn't show up in series 1.
- A lot of stuff and toys in Tommy's room are related to sport like baseballs, skates, a baseball bat, a skateboard and several more. Because Tommy isn't really a sportsperson or enjoys sport it's more likely that he got those items from Dwight. Probably with the intention to let him enjoy and do a sport.
- Outside views of the house suggests that Tommy's room should have a second window that would be located on the wall opposite his bed. But in every scene with his room there's only one window.
