When the adjacent room is underwater it is not possible to gain dash state for the stationary spinjump. Instead, an extremely precise jump is required followed by aiming down to shrink Samus' hitbox. From a full height jump, there are two frames which can touch the transition at the correct height. After entering the next room, hold forward then one frame later aim down. Turning off HiJump may help as it changes which frames work for the trick.
