## Abstract

A shower bathing apparatus is described as including a seat and a first water discharger provided rearward and upward in relation to the seat. The first water discharger is configured to discharge water in a direction forward of the seat. A water discharge direction from the first water discharger and a positional relationship between the first water discharger and the seat may be adjustable so that the water discharged from the first water discharger is able to reach the seat or forward of the seat. The water discharged from the first water discharger may further flow from above a seat occupant's shoulder to the seat occupant's leg.

## Claims

### Claim 1

A shower bathing apparatus for supporting a user in a sitting posture comprising:
a seat configured to receive a bottom of the user, the seat including a front edge;
a back portion configured to receive a back of the user and including a shoulder region located to support shoulders of the user; and
water dischargers solely provided at the back portion and rearward and upward of the seat and having a pair of first water dischargers and a pair of second water dischargers, the pair of first water dischargers being separate from the pair of second water dischargers, the pair of second water dischargers being located outside the pair of first water dischargers, the pair of first water dischargers being provided at the back portion on respective sides of a center of the seat and located upward of the shoulder region and configured to discharge a first continuous water flow from rearward of the seat in a generally horizontal direction toward the front edge of the seat so as to extend beyond the shoulder region and impinge on the seat including the front edge, the pair of second water dischargers being provided at the back portion, located upward of the shoulder region, and located closer to the pair of first water discharges than to the seat surface, which are provided on respective sides of the center of the seat, the pair of second water dischargers being configured to discharge a second continuous water flow from rearward of the seat more downward than the first continuous water flow.

### Claim 2 (depends on 1)

The shower bathing apparatus according to claim 1, wherein the first continuous water flow is discharged in a generally horizontal direction and arcs forward and down toward the front edge of the seat.

### Claim 3 (depends on 1)
