"The NS5000 is a bathing unit primarily used in hospitals for patients who are not able to bathe themselves. It allows them to bathe comfortably and safely. There are often concerns about the water only coming from above and not below. This unit is designed with 16 nozzles in total so that the shower spray also reaches the person's back."
"The RS06 is similar to the NS5000 but is designed primarily for people who are unable to enter a bathtub by themselves. It is for people who would prefer bathing in a wheelchair to lying down. This unit provides a shower mist that covers the entire body while the person is sitting in a reclining chair."
