Diabetes, Foot Care and Walk-In Tub Bathing: Temperature, Foot Jets and Checking Afterward
Diabetes changes one thing about a walk-in tub bath before anything else: if the feet have reduced sensation, they cannot be trusted to judge water temperature, so the water is checked with a thermometer, or held at a set temperature by the thermostatic control valve, rather than tested by stepping in. From there an Ella walk-in tub offers helpful options for foot care, including adjustable foot jets, an intensity dial that softens the flow, and on tubs with independent foot massage, a footwell-only soak that never fills the whole tub. This page describes those features and the foot-care habits the CDC publishes; it is not medical advice, and the person's doctor or diabetes care team decides whether soaking is appropriate at all.
Why Reduced Sensation Changes How You Judge Water Temperature
The CDC explains that nerve damage from diabetes can lower your ability to feel pain, heat or cold, so water that is too hot may not feel too hot to the feet. Ella's owner manuals set the same ceiling for every bather: water in excess of 100.4 F may be harmful to your health, so check and adjust the temperature before use, and consult a physician if you have a medical condition or take medication. For a bather with diabetes that ceiling matters more than usual because the body's own warning system may be quiet. Our warm-water bathing guidelines collect Ella's published temperature and duration guidance in one place.
Use the Thermometer or the TCV, Never the Feet, to Test the Water
| Method | What it tells you | Suitable for a bather with reduced sensation? |
|---|---|---|
| Bath thermometer in the tub water | The actual temperature the skin will sit in. | Yes. Check before sitting and again during a longer soak. |
| Thermostatic control valve (TCV) | Blends hot and cold to a set temperature before the water leaves the faucet. Arrives set at 100.4 F and can be adjusted down. | Yes, as a safeguard on tubs that have one. Confirm with a thermometer the first few baths. |
| Hand or elbow test | A rough feel at the faucet or surface. | Only as a first impression, never as the final check. |
| Foot test | Very little, if sensation is reduced. | No. |
Whether your tub has a TCV depends on the faucet configuration ordered; thermostatic faucet packages include it, while the dual-lever 5-piece and the 2-piece fast-fill faucets are set by hand. Turning a TCV above its 100.4 F factory setting is not recommended. See the thermostatic control valve explained for which faucets include it and how the setting is adjusted.
Foot Jets: Adjustable Nozzles and the Intensity Dial
Ella hydro massage tubs have adjustable lower jets for the calves and feet, and the center nozzle of each foot jet is a valve. Turn the center nozzle to increase, reduce or shut off the flow at that jet. The intensity control dial on the deck sets the overall strength: it is an air control, so turning it down reduces the air mixed into the water for a softer stream, and turning it up adds air for a stronger one. Ella's own FAQ notes that bathers with circulatory concerns such as diabetes may benefit from a hydro jetted tub with the intensity control dial, which lets you soften or strengthen the flow. Start with the dial low and bring it up only as far as the care team is comfortable with. The steps are in adjusting jet pressure and foot jet nozzles.
Footwell-Only Soaks
Tubs built with Ella's independent foot massage have a separate pump and a separate intensity dial for the foot and calf jets. Sit down, close the door, close both drains, fill the footwell to just below the seat and just above the calf jets so every foot and calf jet is covered, and press the foot massage button; the seat jets stay off and there is no need to fill the whole tub. On tubs with a single hydro pump, the foot jets are part of the main system, so the tub must be filled 2 inches above the highest jets before the pump starts. How to use only the foot massage and water level before running jets give the fill levels for each configuration.
Check the Feet After the Bath
The CDC's foot-care tips for people with diabetes include checking the feet every day for cuts, redness, swelling, sores, blisters, corns, calluses or other changes, washing the feet every day in warm rather than hot water, not soaking the feet, drying them completely, and applying lotion to the top and bottom but not between the toes. Because the CDC advises against soaking the feet, whether and how long a person with diabetes bathes is a question for their care team, and an open sore, blister or wound on the foot means asking the doctor before the tub is used at all. After any bath, dry the feet thoroughly and look them over in good light, or have a caregiver do it.
- ☐ Ask the doctor or diabetes care team whether soaking is appropriate and for how long
- ☐ Set the TCV, if fitted, at or below 100.4 F, and confirm with a bath thermometer
- ☐ Never test the water with the feet
- ☐ Start the intensity dial low; reduce or close any foot jet that bothers a tender area
- ☐ Skip the bath and call the care team if there is an open sore, blister or wound
- ☐ Dry the feet completely and inspect them afterward
The Care Team Decides
Read the official guidance: Diabetes and Your Feet, Centers for Disease Control and Prevention. Ella's Bubbles products and content are not intended to diagnose, treat, cure or prevent any disease, and the manuals ask bathers with medical conditions to consult a physician before bathing in warm water.

Common Questions
Can I rely on the thermostatic control valve instead of a thermometer?
Can I close the foot jets completely?
Is it safe to bathe with a sore or blister on my foot?
Does the footwell-only soak work on every Ella tub?
What water temperature does Ella recommend for someone with diabetes?
Talk to the care team. The doctor, podiatrist or diabetes educator who knows the person decides whether warm-water bathing is appropriate, how warm and for how long, and what to do about any change seen on the feet. This page describes the tub's temperature safeguards and foot jet controls so that conversation is easier; it prescribes nothing. For help identifying the faucet and foot jet configuration on your tub, contact your Ella dealer or the team at (800) 480-6850, or open a ticket at ellasbubbles.com/support.
