@mrainne The type of dialysis where you go to a center is hemodialysis, which uses a fistula or graft in your arm to access an artery and "clean" your blood. It typically is done 3 times a week, about 3-4 hours each session. The procedure is handled by trained nurses and professionals. The patient shows up and sits in the chair, everything is done for them. There are no supplies to deal with at home.

The choice on type of dialysis can be based on many factors. Personal preference, for one. To be considered for peritoneal, a person with no to few abdominal surgeries will probably qualify better, as a catheter is surgically implanted. Peritoneal is done at home, and all responsibilities fall to the patient to accomplish the dialysis, with a nurse available as needed via phone. Multitude of supplies, as @ldrlaw and myself will attest, are delivered and must be stored, on a monthly basis. There are fewer fluid restrictions with peritoneal dialysis, and doing dialysis everyday keeps your body on a more even keel.

Ask at your healthcare system if there is a class available for you to take, explaining the types of dialysis, so they know you are thinking ahead. And, good for you for doing that!
