Invacare Aquatec Ocean Ergo Attendant Shower Commode Chair
/
The Invacare Aquatec Ocean Ergo Attendant Shower Commode Chair is a caregiver-pushed rolling shower commode built on the same ergonomic Ergo platform as the self-propel model — with 4" rear casters instead of 24" wheels. The caregiver pushes via rear push handles; the user does not self-propel. The ergonomic contoured seat encourages an upright, stable position. Every adjustment is tool-free. The stainless steel frame is fully rust-proof and cleanable in a chair washer or autoclave. Includes collection pan, lid, and pan support guide rail. Available in standard (330 lbs, OCEANERGO) and XL (400 lbs, OCEANERGOXL).
Why the Aquatec Ocean Ergo Attendant
The Ocean Ergo Attendant is designed for users who require full caregiver assistance for all mobility — including in the shower and for toileting. The 4" rear casters keep the chair compact and highly maneuverable by the caregiver in tight bathroom spaces. There are no hand rims and no expectation of user self-propulsion. The caregiver controls all movement via the rear push handles.
Despite being the attendant (non-self-propelling) model, the Ocean Ergo Attendant is not a basic shower chair. It is a clinical-grade system with the same ergonomic platform, tool-free adjustability, stainless steel construction, and 3-in-1 use capability as the self-propel version. The defining advantage over basic shower chairs: the ergonomic contoured seat that positions the user upright and stably, reducing the postural support burden on both the user and the caregiver during bathing and toileting tasks.

Who This Chair Is For
The Aquatec Ocean Ergo Attendant is the right chair when:
- The user has limited or no upper body function and cannot self-propel — due to neurological conditions, severe weakness, post-surgical recovery, or cognitive impairment
- A caregiver is consistently present for all bathing, toileting, and transfer activities
- The bathroom space is tight and the narrower 4" caster profile fits the layout better than a 24" rear wheel chair
- The user is transitioning from a hospital or skilled nursing facility environment where attendant care was provided, and similar attendant care continues at home
- The patient has significant postural support needs and benefits from the ergonomic contoured seat, but does not need or cannot use self-propulsion
This is not the right chair for: Users who can self-propel — the OCEANERGOSP gives them independence that this model cannot provide. Users who need tilt-in-space or recline capability — see the Aquatec Ocean Ergo Dual VIP (OCEANERGODUALVIP). Users who need a basic, low-cost shower seat without clinical positioning features — standard shower chairs are more cost-effective for that use case.

Wheelchair Measuring Guide
Wheelchair Measurements:
- Hip Width:
Use this to figure seat width if it is the widest point. - Widest Point:
Measure the widest area across the lower extremities if different from the hip width. This may influence seat width or arm style. - Chest Width:
Measure the widest point of the thorax just below the arm pit. This measurement may influence system width or back width. - Heel to Knee:
Use this for legrest extensions and seat height. - SRP to Knee (Seat Reference Point to Knee):
This will determine the seat depth. - Elbow to SRP (Elbow to Seat Reference Point):
Measure this width with the arm in a 90 degree angle at the elbow and the shoulder in a neutral position. - Shoulder Height:
This will determine the height and the style of the back panel or the start for a custom back. - Head Height:
This will help determine the proper headrest height.
