Most people can shower within the first few days after knee surgery, as long as the incision stays dry and protected. The exact timing depends on your procedure and your surgeon’s instructions, but the bigger challenge is doing it safely when your knee is swollen, stiff, and unable to bear full weight. Here’s how to set up your bathroom, protect your wound, and get through that first shower without a fall or an infection scare.
When You Can Start Showering
For arthroscopic knee surgery (the kind done through small incisions with a camera), many surgeons allow showering within 24 to 48 hours. For total knee replacement, the timeline is similar, though some surgeons ask you to wait until a follow-up visit confirms the wound looks good. Your surgical dressing may already be waterproof, but that doesn’t mean you should let water run directly over it without added protection.
The critical rule: showering is fine early on, but submerging your knee in water is not. That means no baths, hot tubs, or swimming pools for at least six weeks after surgery. Standing water harbors bacteria far more effectively than running shower water, and a healing incision is an open door for infection. Most surgeons hold firm on this six-week minimum regardless of how good the wound looks.
How to Protect Your Incision
Even if your post-surgical dressing is labeled waterproof, adding a layer of protection is smart. Glad Press’n Seal (the kitchen plastic wrap with a sticky side) is one of the most commonly recommended options. It molds to the contours of your knee, sticks to skin without tape, and creates a reliable seal against water. Wrap it around the entire dressing so no edges are exposed.
If Press’n Seal isn’t available, you can use regular plastic wrap secured at the top and bottom with waterproof medical tape. The goal is a complete seal with no gaps where water could seep in. Avoid letting the shower stream hit your knee directly, even with a covering in place. Angle your body so the water runs down your leg rather than pooling around the dressing.
A study comparing four popular surgical dressings found that many products marketed as waterproof still allowed measurable water penetration, especially during submersion. This is another reason baths are off-limits and why adding that extra plastic layer matters even with a “waterproof” dressing.
Setting Up Your Bathroom
Preparing the space before your first shower matters more than most people expect. A wet bathroom floor and a leg you can’t fully control is a recipe for a fall, and a fall in the first weeks after knee surgery can set your recovery back significantly.
Start with a shower chair or tub transfer bench. Look for one with non-slip feet and sturdy armrests, since the armrests are what you’ll push off of when sitting down and standing up. A transfer bench is especially useful if you have a tub with a high lip to step over: it lets you sit on the bench outside the tub, then slide across and swing your legs in, rather than stepping over the edge on one leg.
A handheld showerhead is close to essential. When you’re sitting, a fixed overhead shower sprays everywhere except where you need it, and you end up twisting and reaching in ways that stress your knee. A handheld unit on a flexible hose lets you direct water precisely and keep it away from your incision when needed. Most attach to your existing shower arm in minutes without tools.
A few other items that make a real difference:
- Non-slip mats inside and outside the shower or tub. Wet tile is the most common fall hazard.
- Grab bars mounted on the wall near the shower entrance. Towel racks are not grab bars and will pull out of the wall under your weight.
- A long-handled sponge so you can wash your lower legs and feet without bending your knee deeply or leaning forward and losing balance.
- A leg lifter (a stiff strap with a loop) to help you raise your surgical leg over a tub edge if needed.
Before your first shower, remove any loose bath mats or rugs that could slide underfoot. Move your soap, shampoo, and towel to a height you can reach while seated. If your shower has a glass door on a track, consider switching temporarily to a curtain. Glass door openings are narrow, the tracks create a tripping hazard, and getting a shower chair through them can be nearly impossible.
Getting In and Out Safely
The basic principle for moving after knee surgery is “lead with the good leg going up, lead with the surgical leg going down.” For stepping into a shower or tub, this translates to: step in with your non-surgical leg first (it’s bearing your weight on the way down into the tub), then bring the surgical leg in after you’re stable. When getting out, reverse it: surgical leg comes out first, then push up and step out with your strong leg.
If you’re using a transfer bench, sit on the part of the bench that extends outside the tub, use your hands on the armrests for support, and slide your body across while swinging your legs over one at a time. Keep the surgical leg as straight as comfortable during the transfer. Have someone nearby for your first few showers, not necessarily in the bathroom, but close enough to hear you if something goes wrong.
Place a sturdy chair just outside the bathroom door. After you shower, you can sit there to dry off, apply fresh dressings, and get dressed without standing on a wet floor or balancing on one leg.
Drying and Checking Your Incision
After showering, remove the plastic wrap and pat the area around your incision dry with a clean towel. Don’t rub. If the dressing underneath got damp despite your efforts, replace it with a fresh one rather than leaving a wet bandage against your skin.
Each shower is a good opportunity to look at your incision. Some redness and swelling right around the wound edges is normal in the first couple of weeks. What’s not normal: redness that spreads outward from the incision over time, warmth that feels noticeably hotter than the surrounding skin, pus or cloudy drainage, increasing pain rather than gradually decreasing pain, or a fever. These are signs of a surgical site infection and need prompt attention.
Once your staples or stitches are removed and your surgeon confirms the incision has fully closed, you can typically stop covering it for showers. Until then, keep protecting it every single time. A few extra minutes of prep before each shower is a small price for an infection-free recovery.
