The extension hose carries water from the Orca bath tub to the floor waste or the drain point, so the tub can be emptied where it stands. It saves the carer tipping or dragging a full tub, which is the part of the job most likely to cause a strain or a spill.
Length matters in bathrooms where the outlet is not directly under the frame, and the hose gives you the reach to set the Orca up where the carer can work. It drains fully and stores with the tub between uses.
This is the R82 part for the Orca drain fitting.
