Technically, yes. A boat bath is different to slipper tubs by virtue that the bateau design is generally double-ended, not single-ended. However, a slipper’s end can vary in shape and curve differentiating it slightly in shape, whereas a boat bath tends to always follow the smooth, sweeping and symmetrical curve associated with the name. Nevertheless, some people do refer to boat or bateau baths as 'double ended slipper baths'.
