Dialysis Access Sites, Open Wounds and When Not to Bathe in a Walk-In Tub
If you are on dialysis, have a catheter or other access site, or are healing an open wound, the honest answer to "can I soak in my walk-in tub?" is that your dialysis team or wound clinic decides, not this page and not the tub. What Ella's Bubbles can tell you is exactly what the tub's features do so you can follow the clinic's instructions faithfully: ozone sanitation and the monthly vinegar flush keep the tub's water system fresh but are not medical disinfection, the hand shower and optional shower column let you wash seated without filling the tub at all, and the jets recirculate bath water across the skin. This page lays those facts out and points to the CDC's dialysis safety guidance. It is not medical advice.
The Honest Rule: The Dialysis Team or Wound Clinic Decides
Ella's owner manuals ask anyone with a medical condition to consult a physician before bathing, and Ella's published terms state that its products and content are not intended to diagnose, cure or prevent any disease. For dialysis patients and people with open wounds that guidance is not a formality. The people who placed the catheter or fistula, or who are managing the wound, are the only ones who know whether it can be submerged, covered, or must stay dry. Bring them the facts on this page and follow what they say.
Catheters and Access Sites: Keep-Dry Instructions Come from the Clinic
The CDC's dialysis safety materials for patients ask you to check your access every day, to notify the dialysis staff if your catheter bandage gets dirty or wet, and to report redness, swelling, pus or unusual drainage. Your clinic may tell you not to submerge a catheter at all. Whatever your clinic tells you overrides anything general, including the water-level guidance elsewhere on this site: if the instruction is "keep it dry," the tub is used for a seated shower or a footwell-only soak, or not at all, until the clinic says otherwise.
What Ozone and the Vinegar Flush Do and Do Not Do
| Feature | What it does | What it does not do |
|---|---|---|
| Ozone sanitation | Runs automatically whenever the hydro massage pump runs, releasing ozone into the water system to eliminate mold and bacteria in the lines and prevent mildew and odor. Included with every hydro package. | It is a hygiene feature for the tub's water lines, not a medical disinfectant. It does not replace monthly cleaning, and it has no bearing on whether a wound or access site may be submerged. |
| Monthly vinegar flush | Mix 2 cups white vinegar with 2 cups water, fill the tub to 1 inch above the highest jets, add the mixture, run the jets for 10 minutes, then drain. Done before first use and once a month. | It cleans the pump circulation lines; it is not a disinfecting step for the bather, and flushing after every bath is not needed. |
| Auto-Purge (air massage tubs) | Blows the air lines clear for 120 seconds about 20 minutes after the air pump is switched off, so standing water cannot sit in the lines. | It does not clean the tub surface or the bath water. |

For wiping the tub down between baths, use only products from the published list in approved cleaners and chemicals to avoid. Avoid bath bombs, and note that oils, fragrances and salts are allowed but not suggested for any tub; whether any additive is appropriate near a wound is a question for the clinic.
Showering in the Tub Instead of Soaking
Every Ella fast-fill faucet set includes a pull-out hand shower with five spray settings on a 5 foot retractable hose, limited to 1.9 GPM, so a seated shower with the drains open is built in from day one. On the 2-piece faucet you push the diverter button under the spout to send water to the hand shower; on the 5-piece faucet you turn the middle diverter lever. Because the drains stay open, the water level never rises and an access site above the footwell stays out of the water. Please do not hang the hand shower on the wall unless the barrel extension hose is installed, or water can leak behind the tub.
For a full overhead shower, the optional Shower Column Kit adds a 10 inch pivoting rain shower head to any tub with an Ella 2-piece or 5-piece deck-mount faucet, adjustable in height and usable seated or standing. By design the rain head and the hand shower do not spray at the same time; the diverter selects one. See showering in your walk-in tub and shower column kit installation.
Jets and Healing Skin
Hydro massage jets recirculate the bath water and push it back across the body, and air massage jets push air up through the water from the seat and floor. Neither is a wound-care device, and the manuals ask that a physician be consulted for any medical condition. If the clinic does allow a soak, the intensity control dial on every hydro tub can be turned down for a softer stream, individual foot jets can be reduced or closed at the center nozzle, and a still soak with no jets at all is always an option.
When to Skip the Bath Entirely and Call the Care Team
- ☐ The clinic has said the catheter, fistula or graft site must stay dry
- ☐ A wound is open, draining, or has a dressing that must not get wet
- ☐ There is new redness, swelling, pus or unusual drainage at an access site
- ☐ The catheter bandage is dirty or wet and the dialysis staff have not yet been told
- ☐ You have not yet asked the dialysis team or wound clinic whether soaking is allowed
If any box is checked, use the seated shower or wait, and ask the care team. Ella's guidance on temperature and duration for everyone is in warm-water bathing guidelines, and it applies only once the clinic has said a soak is appropriate.

Common Questions
Does the ozone system make the bath water clean enough for an open wound?
Can I use my walk-in tub as a shower on dialysis days?
Can I soak just my feet while keeping a chest catheter dry?
Are the jets safe on healing skin?
Talk to the care team. Your nephrologist, dialysis nurses or wound clinic decide whether you may soak, shower or must keep a site dry, and for how long. This page describes what the tub's sanitation, shower and jet features actually do so you can follow those instructions; it prescribes nothing. For questions about the hand shower, shower column or cleaning routine on your tub, contact your Ella dealer or the team at (800) 480-6850, or open a ticket at ellasbubbles.com/support.
