The bedroom is essentially the same set as the living room , redressed with different furniture . It includes two single beds ( one for Bert and one for Ernie ) , a night stand and lamp . Again windows are present that allow Bert and Ernie to look out to the moon and stars . In " I Love My Toes " a view of the floor of the bedroom shows it is bare and has toys lying around . Bathroom . The bathroom includes " Rosie " the bathtub and is home to Rubber Duckie . Ernie is often seen bathing and singing in the bathroom . Oddly , no toilet is visibly present . There have been a number of different bathroom sets . In the original version of the song " Rubber Duckie " and the first episode , the living room set was used , with a bathtub in the set . In the second version of " Rubber Duckie " , the bathroom was a plain blue background , with a bathtub . In a sketch in which Bert attempted to give his nephew Brad a bath , the bathtub was closer to the back wall of the bathroom , while in " Christmas Eve on Sesame Street " it is farther from the back wall , and in the song " Do De Rubber Duck " , the bathroom consisted of a bathtub , one wall , a visible sink , and a visible clothes hamper . Ernie ' s room . In at least two sketches , Ernie is seen to have had his own hobby room . , Ernie is smelling flowers when Bert enters and asks , " When are you going to clean up your room ? " Ernie says he ' ll clean it the Tuesday after next . Ernie keeps a fish mobile in his room , a grandfather clock as well as toys and laundry tossed around the room . The room was also seen in where Ernie says he has " flying fingers " and tries to find ten different things that his fingers can do . Variations . Over the years the sets have evolved and changed slightly . During the first season of Sesame Street , there were a couple of scenes depicting only one bed in a bedroom , implying separate bedrooms . Several illustrated books also show separate bedrooms for Ernie and Bert depending on story needs . At least one book , My Name Is Ernie , depicts the apartment as being on an upper floor of the building , not the basement . In the film " Follow That Bird " , a remade living room was shown that was more detailed and realistic than the version seen on the show . In " Bert and Ernie ' s Great Adventures " , they have a whole new bedroom , shown to be the top floor of the apartment building .
