Aquatec Ocean Ergo Self-Propel Shower Commode Chair
/
The Aquatec Ocean SP is the self-propelled version of the Aquatec Ocean Ergo line — built for users who have enough upper body strength to move independently and don't want to wait for a caregiver to position them for showering or toileting. The 24" rear wheels with hand rims let the user propel and steer the chair themselves, the same way a manual wheelchair works. Flip-up armrests and generous space in front of the rear wheels make side transfers straightforward without requiring caregiver assistance for the transfer itself.
The seat is ergonomically contoured and pre-tilted at a gentle 5° angle — designed to encourage a more natural, upright sitting position during both showering and toileting rather than the passive slumped posture that flat shower seats often produce. Seat height, footrest height, and footplate angle all adjust without tools. The frame is rust-proof stainless steel and high-quality plastic throughout — built for daily wet-environment use. Machine-washable upholstery. Collection pan with lid and pan support guide rail included.
Supports up to 330 lbs. Fits over most standard toilets for independent toileting without transferring out of the chair. The narrow overall width of 22" navigates standard residential doorways without difficulty.

Frequently Asked Questions
Who is the Ocean SP actually designed for?
Users with sufficient upper body strength and coordination to propel and steer a manual wheelchair independently. If the person using the chair can self-propel a standard wheelchair for daily mobility, the Ocean SP will work for independent shower and toilet use. If upper body strength is limited or inconsistent, the attendant-propelled Ocean Ergo is the better fit — call us and we'll help you decide.
What does the 5° seat tilt actually do?
The pre-tilted seat angle shifts the pelvis slightly forward and encourages a more upright trunk position. In practical terms this reduces the tendency to slump backward during showering, which matters both for comfort during longer sessions and for hygiene access. It also produces a more natural toileting position compared to a flat seat at the same height.
Can it roll over a standard toilet for independent toileting?
Yes — the narrow 22" overall width and tight wheelbase are specifically designed to fit over standard residential toilets. The seat height adjusts from 19" to 24", covering both standard and comfort-height toilets. The collection pan removes and the chair positions directly over the toilet bowl.
How do side transfers work with this chair?
The armrests flip fully up on either side, and the 24" rear wheel positioning leaves enough space in front of the wheels for a lateral transfer from a bed or wheelchair. The relatively flat seat surface also simplifies transfers compared to more contoured or reclined designs.
Does it disassemble for transport?
The rear wheels are quick-release for easier transport and storage. The chair disassembles without tools. It's not a compact travel chair like the Seatara BathMobile — it's heavier and larger — but it's manageable for car transport between locations.
Is an XL or bariatric version available?
The Ocean Ergo XL supports up to 400 lbs with a wider seat and frame. If the standard 330 lb capacity is insufficient, call us to discuss the XL configuration.

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.
