How Soon Can I Shower After Knee Replacement Surgery?
Apr, 26 2025
First things first—after knee replacement surgery, you’re probably dreaming of that first real shower. Hold up, though. Jumping in too soon can mess up your healing knee and increase the risk of infection, which could mean another trip to the hospital. The tricky part? There’s not one-size-fits-all rule; it depends on your wound, your dressing, and what your surgeon says.
If your doctor has put a waterproof bandage over your incision, you might be able to shower after a couple of days, maybe even sooner. Still, don’t peel that bandage off or scrub the wound. And definitely skip soaking in a tub or hot tub for now. Open wounds and bacteria from water don’t get along.

Why You Need to Wait to Shower
After a knee replacement, your skin is still healing, and the incision isn’t sealed up like regular skin yet. If you shower too soon, you risk getting water and germs in that fresh cut, which can lead to a nasty infection. About two out of every 100 people who get knee replacement surgery end up with an infection at the surgical site, and most of those infections show up in the first few weeks. That might sound like a small number, but when it happens, it can mean big trouble—sometimes it leads to more surgeries or even hospital stays.
Doctors say you should only shower when your bandage is totally waterproof. Some modern dressings are designed to be water-resistant, but not every hospital uses them. If your bandage or wound gets wet too soon, you might have to go back to the clinic to get it checked or replaced.
Here’s what can happen if you shower at the wrong time:
- Bacteria from tap water sneak into your wound
- Your wound care gets complicated if the surgical dressing peels off
- Moisture slows down the healing process of your skin
- You might accidentally slip if you’re not steady on your feet yet
Your doctor isn’t just being picky—they’re aiming to protect you from setbacks that could drag out your recovery. Bottom line, it’s all about stopping germs and giving your knee the best shot at a solid recovery.
Safe Timelines for Showering Post-Surgery
The countdown to your first shower after knee replacement depends on how your wound is healing and what your surgeon recommends. For most people, the go-ahead comes somewhere between 2 to 14 days after surgery. If you have a special waterproof bandage, you might get that green light even sooner—sometimes in as little as 48 hours.
Here's how the typical timeline breaks down:
- Days 1–2: Sponge baths only. Keep the surgical area completely dry.
- Days 3–7: If your dressing is waterproof, it’s usually safe to shower. If not, stick with sponge baths.
- Week 2 and beyond: Most people with healed incisions and no drainage can shower without a bandage. Avoid scrubbing or soaking the knee.
What makes a dressing “waterproof”? If water beads up and rolls off (like plastic film dressings), it’s usually fine for brief showers. Gauze or fabric dressings, on the other hand, are not waterproof and should not get wet at all. Don’t try to cover a non-waterproof bandage with a plastic bag and hope for the best—water always finds a way in.
Hospitals in the U.S. and the U.K. reported that patients with waterproof dressings could safely shower by day 3 without more complications than those who waited longer. Waiting longer isn’t always better, especially if you feel sticky and frustrated. But follow your doctor’s instructions, even if you’re eager to feel fresh again.
Check out this quick breakdown to keep things straight:
| Time After Surgery | Safe to Shower? | Special Notes |
|---|---|---|
| 48 hours | Maybe | Only with waterproof dressing |
| 3–7 days | Often | Depends on dressing type and wound |
| 7–14 days | Usually | Incision should be closed, no drainage |
If there’s any bloody or yellow drainage, or if the incision is not fully closed, skip the shower and let your surgeon know. When in doubt, call your clinic. Every knee and every recovery is different.
How to Shower Without Risk
When it comes to taking a shower safely after knee replacement surgery, it’s all about protecting your incision and keeping things simple. Even if you’re cleared for a quick shower, there’s still plenty to watch for. Wet bandages or letting water get into your wound can lead to infection fast—and that’s honestly the last thing you want.
First, check with your surgeon what type of dressing you have. If it’s a waterproof bandage, you can usually shower after 48 hours, but regular (non-waterproof) dressings need to stay dry even during a shower. For those, you’ll have to cover your knee tightly with plastic wrap or a specific shower cover.
Here’s a step-by-step approach for your first few showers post-op:
- Make sure your bathroom is set up before you get started—grab a sturdy chair, a non-slip mat, and keep everything within arm’s reach.
- Cover your incision and bandage thoroughly if it’s not waterproof. Tape the edges well or use a purpose-made leg cover (many drugstores sell these).
- Use lukewarm, not hot, water. Hot water can make you dizzy, especially right after surgery.
- Avoid directing the shower stream straight at your incision. Let it run gently over the leg instead.
- Do not scrub near the incision and don’t pick at the surgical glue, staples, or scabs. Just use mild soap on the rest of your body.
- When you’re done, pat your knee area dry with a clean towel. Don’t rub the incision.
- Replace any wet bandages if needed, and keep watching for redness, swelling, or leakage—these are signs to call your doctor ASAP.
Many physical therapists suggest sitting for the first few showers since you might feel weak. It’s safer and a lot less stressful. Another pro tip? Bring someone you trust to help you if you feel shaky or nervous, even if it’s just to hand you a towel.
Here's a quick table with a few common dressing types and their shower rules:
| Dressing Type | Showering Allowed? | Special Instructions |
|---|---|---|
| Waterproof | Yes (after 48 hours) | Don’t remove for 7 days or as told by your doctor |
| Gauze/Regular | No | Cover with plastic, keep completely dry |
| Steri-Strips/Glue | Yes (after 48-72 hours) | Pat dry, no soaking, don’t peel strips |
Stick to these basics and you’ll lower your risk while still enjoying that fresh-out-of-the-shower feeling. Remember, clean doesn’t mean risky—play it safe so your new knee heals right.
Real-World Tips for a Hassle-Free Experience
Alright, you want to make your first shower after knee replacement as stress-free as possible? Let’s get into the nitty-gritty. People who've just had knee surgery all agree—planning ahead makes things smoother and way safer.
- Set up before you get wet: Have all your shower stuff within reach. Slip-resistant mats, a stable shower chair, and a handheld showerhead can be game-changers. These are the same tools hospitals use when teaching post-op care.
- Keep it short: Try to keep your showers quick, usually under ten minutes. Less steam means the bandage adhesive is less likely to peel off, and you’re on your feet less, which is good for early knee surgery recovery.
- Ask for help if you need it: The first shower is no time for heroics. Having someone nearby—even if they just stand outside the door—can add extra peace of mind.
- Dry carefully: Pat your wound care area dry, don’t rub. A clean towel works best. Make sure skin around the bandage is dry to avoid bacteria and irritation.
- Change dressings if needed: If your waterproof bandage loosens, replace it after your shower, following your surgeon’s instructions. Don’t reuse old dressings.
Did you know? According to a report by the American Association of Hip and Knee Surgeons, about 65% of patients use a shower chair for their first week post-surgery and report fewer slips.
| Item | How it helps |
|---|---|
| Shower chair | Provides support and takes weight off your leg |
| Non-slip mat | Reduces danger of sliding or falling |
| Handheld showerhead | Makes cleaning around your knee easier |
| Waterproof bandage | Keeps water away from the surgery wound |
Pay attention to your body. If the area around your wound looks red, swollen, or starts leaking, hold off on showers and call your doctor. Sticking to these real-world tips can keep your recovery on track—and hopefully, let you enjoy that first post-surgery shower without extra worry.
