It is identified as the Officer's Gym - Caligula Suite in the extended scene in The Bodysnatcher Collection.
Three million years later, the hologram Rimmer once swapped consciousness with the human Dave Lister, promising to use the gymnasium to get Lister's body fit. However Rimmer didn't do this, instead using the hot tub of the Captain's quarters.
Behind the scenes
- Kryten was originally supposed to have featured in this scene. The mechanoid would have approached Rimmer (in Lister's body) when called over as Rimmer soaked in the hot tub, and would have lit Rimmer's cigar with a flame produced from his finger. Such a device was produced and the scene was filmed; in fact, it was the first scene Robert Llewellyn ever filmed as Kryten. However the device kept misfiring, repeatedly electrocuting Robert. The scene was scrapped (Series III DVD booklet), and was believed lost for many years, but later recovered and included in the bonus features of The Bodysnatcher Collection for "Bodyswap".
