The butterfly bathtub, also known as an 8-shaped bathtub or Hubert bathtub, is named for its butterfly-shaped cross-section. Designed to accommodate most patients' post-illness body positions, it allows patients to stretch their torso and limbs within the tub. The design facilitates medical staff access from multiple angles for treatment. Combined with a rotating arm stretcher transfer system, it enables easy entry and exit for patients with mobility issues. Listed in the rehabilitation assistive device catalog and certified with CE, this product is suitable for hospitals, nursing homes, and households alike.
