Home dialysis turns a spare room, bedroom corner, or even a closet-adjacent chair into a personal treatment space where you filter waste from your blood on your own schedule. There are two main types: peritoneal dialysis, which uses the lining of your abdomen to filter blood, and home hemodialysis, which uses a machine to filter blood directly. Each one looks and feels quite different day to day, so the practical reality depends on which route you and your kidney care team choose.
The Two Types at a Glance
Peritoneal dialysis (PD) works by filling your abdominal cavity with a sterile fluid through a small, permanently placed catheter near your navel. The fluid draws waste and extra water out of your blood through the lining of your abdomen, and after a set dwell time you drain it out and replace it with fresh fluid. You can do this manually throughout the day (called CAPD) or hook up to a small bedside machine called a cycler that runs exchanges automatically while you sleep (called APD).
Home hemodialysis (HHD) looks more like what you’d see in a dialysis center, scaled down. A compact machine pumps your blood through a filter, cleans it, and returns it. You connect to the machine through a vascular access point in your arm or chest. Sessions can happen during the day in shorter blocks or overnight while you sleep, depending on your prescribed schedule.
What the Treatment Space Looks Like
For home hemodialysis, your treatment area needs a grounded electrical outlet, a water source, and a drain or plumbing connection to dispose of used fluid. Some people set up in a bathroom or laundry room where plumbing already exists. Others run lines to a bedroom or living room. Minor home modifications, like adding a dedicated outlet or extending a drain line, are common. The machine itself is roughly the size of a large suitcase or small filing cabinet.
Peritoneal dialysis requires less infrastructure. The cycler machine is about the size of a carry-on bag and sits on a nightstand or small table. It doesn’t need special plumbing; you drain used fluid into bags or a nearby toilet. The bigger space issue is storage. Dialysis supplies arrive monthly, and a month’s worth of fluid bags and tubing fills a significant number of boxes. Many people dedicate a closet, a section of a spare room, or a set of shelves. In smaller apartments, you may be able to arrange partial deliveries to reduce how much you store at once.
Regardless of the type, the treatment space should be clean, well-lit, pet-free during sessions, and comfortable enough that you can sit or lie down for the duration. Some people rearrange furniture, add brighter lighting, or declutter an area specifically for this purpose.
What a Typical Day Looks Like
If you’re doing manual peritoneal dialysis (CAPD), you’ll perform about four exchanges spread throughout the day. Each exchange takes roughly 30 to 40 minutes of active time: you drain the old fluid, let fresh fluid flow in, then go about your life while it dwells inside your abdomen for several hours before the next exchange. The standard dwell volume for most patients is about two liters per exchange, with four hours between swaps. Many people do exchanges around meals and bedtime, fitting them into a routine.
Automated peritoneal dialysis shifts almost all of this to nighttime. You connect to the cycler before bed, and it runs exchanges automatically over 5 to 12 hours while you sleep. In the morning, you disconnect and have your day largely free. Some prescriptions include one daytime dwell where fluid sits in your abdomen during the day and you drain it in the evening before reconnecting.
Home hemodialysis schedules vary more. Some people dialyze for 3 to 4 hours during the day, several times per week. Others do nocturnal hemodialysis, running the machine for about 8 hours overnight, three or more nights per week. Longer, slower sessions filter blood more gently, which tends to cause fewer side effects like cramping and fatigue compared to the compressed 3.5-hour sessions typical of in-center treatment.
The Training Process
You won’t be sent home to figure this out alone. Before starting, you and often a care partner go through structured training at a dialysis clinic. For peritoneal dialysis, training typically takes one to two weeks of daily sessions. You learn sterile technique for connecting and disconnecting, how to spot signs of infection, and how to troubleshoot alarms on the cycler.
Home hemodialysis training is more involved. Programs often require three to four sessions per week, each lasting about four hours, over the course of several weeks to a few months. During training, you learn to set up and take down the machine, manage your vascular access (including self-cannulation, which means inserting your own needles), respond to alarms, and handle emergencies like blood pressure drops. Self-cannulation is usually introduced in the second week. As patients gain confidence, total training time tends to shorten. Your clinic stays available by phone for support once you’re treating at home.
The Care Partner’s Role
For peritoneal dialysis, many people manage independently. Home hemodialysis more often involves a care partner, typically a spouse, family member, or close friend, who trains alongside you. The care partner’s responsibilities vary based on your needs and may shift over time. Common tasks include helping set up the treatment space, organizing and stacking supply deliveries, preparing meals that fit your dietary plan, and being present during treatments in case something needs attention.
The goal is generally for the person on dialysis to handle as many tasks as possible themselves, with the care partner filling gaps. Some care partners take on a more active clinical role; others mainly provide logistical and emotional support. The National Kidney Foundation recommends that both of you discuss and plan task division before treatments begin at home, with the understanding that roles evolve.
Costs and Insurance Coverage
Medicare covers home dialysis for people with end-stage kidney disease regardless of age. Under Medicare Part B, the standard cost-sharing structure is 20% of the Medicare-approved amount for each treatment, whether it happens in a center or at home, after you meet your annual deductible. Training sessions are covered with a specific add-on payment, so you’re not paying extra to learn. Equipment, the machine, and supplies are provided through your dialysis provider and billed to insurance.
Private insurance plans vary, but most major insurers cover home dialysis similarly to in-center treatment. Your dialysis provider typically handles supply orders, delivery logistics, and insurance billing. Out-of-pocket costs for utilities, water and electricity, do increase. Home hemodialysis uses more water and power than peritoneal dialysis because of the filtration process. Some programs offer utility reimbursement or assistance.
Infection Risk and Safety
The biggest ongoing safety concern with peritoneal dialysis is peritonitis, an infection of the abdominal lining. It happens when bacteria enter through the catheter site, usually due to a break in sterile technique during connections. In a large cohort study, the risk of a severe infection during the first year was 35% for manual PD patients and 25% for those using an automated cycler. The automated method has lower infection rates partly because it involves fewer manual connections each day.
Home hemodialysis carries a much lower infection rate overall. In the same study, the incidence of dialysis-related infections like peritonitis was zero among home hemodialysis patients, though other types of infections (related to vascular access, for example) still occur at a rate of about 197 episodes per 1,000 patient-years. That’s roughly a third the rate seen in manual PD. Rigorous hand hygiene and following the sterile steps you learn in training are the most important things you can do to stay safe.
Managing Supplies and Waste
A steady stream of cardboard boxes and plastic packaging is one of the less-discussed realities of home dialysis. Supplies arrive monthly by delivery truck, and you’ll need a plan for both storage and disposal. Used drain bags, fill bags, and tubing go into heavy garbage bags and out with regular household trash. Dialyzers and bloodlines from hemodialysis aren’t recyclable, but cardboard boxes, dialysate bottles, and most outer packaging can be recycled normally. Rolling up empty bags and wrapping them with tubing before tossing helps compress the volume significantly. Used medication vials are treated like any household item, no special sharps disposal is required unless you’re discarding needles, which go into a sharps container your provider supplies.
Traveling With Home Dialysis
Travel is possible on both types of home dialysis, though it requires planning. For peritoneal dialysis, your dialysis provider can ship supplies ahead to your destination, whether that’s a hotel, a relative’s house, or a vacation rental. The cycler machine is portable enough to check as luggage or carry in a vehicle.
Air travel has specific protections. Under Department of Transportation rules, portable dialysis machines are classified as assistive devices. Airlines cannot count them against your carry-on or checked baggage limits, cannot charge fees for transporting them, and must give them priority stowage over other passengers’ items if you pre-board. Medications, syringes, and dialysis fluids also qualify as assistive devices. Airlines are generally required to accept machines weighing up to about 100 pounds including their carrying case. However, carriers can limit the quantity of dialysis fluid they accept to a one or two day supply, so larger fluid shipments need to be arranged separately to your destination.
Planning ahead by two to four weeks gives your care team enough time to coordinate supplies, adjust your treatment schedule if needed, and provide documentation for the airline or TSA.
