A catheter bag cover is a simple fabric pouch that hides a urine collection bag from view, and you can make one at home with basic sewing skills in under an hour. The most common design is a drawstring pouch, similar to a small purse, that slips over a standard leg bag or bedside drainage bag. Here’s how to measure, cut, sew, and customize one that actually works.
Choosing Your Fabric
Cotton and cotton-blend fabrics work best. They’re breathable, easy to wash at high temperatures, and won’t trap moisture against the bag. Quilting cotton is a popular choice because it comes in a huge range of patterns, letting the user pick something that feels personal rather than medical. Avoid fabrics that are too thick or stiff, since the cover needs to drape naturally against the leg or wheelchair frame without adding bulk.
You’ll want fabric that can handle hot water laundering. The CDC recommends washing items exposed to body substances at 160°F (71°C) for at least 25 minutes to reduce microbial contamination. Pre-wash your fabric before cutting to account for shrinkage and confirm it holds up to heat.
Measuring and Cutting
Standard catheter leg bags come in two common sizes. Hollister’s models, for example, are about 11 inches long for the 540 mL version and 10 inches long for the 900 mL version (the larger capacity bag is wider rather than longer). Other brands vary slightly, so the easiest approach is to lay the actual bag flat on your fabric and measure it directly, then add about an inch on each side for seam allowance and a comfortable fit.
A widely used starting dimension is 14 inches wide by 13 inches tall. This accommodates most standard leg bags with room to spare. You need either two pieces cut to this size (front and back) or one piece that’s 14 inches wide by 26 inches tall, which you’ll fold in half. If you’re covering a larger bedside drainage bag, scale up accordingly, measuring the bag first and adding your seam allowance.
You can make the bottom corners rounded or squared. Rounded corners give the finished cover a softer look and reduce fabric bunching at the edges. To round the corners, trace around a drinking glass or small plate before cutting.
Sewing the Basic Pouch
The construction is straightforward: you’re making a three-sided pouch with an open top.
- Step 1: Place your two fabric pieces right sides together (printed sides facing each other). If using a single folded piece, fold it right sides together so the fold becomes the bottom of the pouch.
- Step 2: Sew along three sides (both sides and the bottom) using a half-inch seam allowance. Leave the top completely open. If you folded, sew only the two side seams.
- Step 3: Create the drawstring casing at the top. Fold the top edge down about a quarter inch, press it, then fold it down again about three-quarters of an inch. Sew along the bottom edge of this fold, leaving a small gap (about one inch) on each side so you can thread a drawstring through.
- Step 4: Turn the pouch right side out. Thread a shoelace-style cord or ribbon through the casing using a safety pin as a guide. Knot each end of the drawstring so it can’t pull through.
That’s the finished cover. It slips over the catheter bag and cinches closed at the top around the tubing, completely hiding the bag’s contents.
Adding a Viewing Window
One of the most useful upgrades is a small clear window that lets you check fluid levels without removing the cover. Commercial catheter bag covers often include this feature, and it’s easy to replicate.
Cut a rectangular opening in one side of the fabric, roughly 2 inches wide by 3 inches tall, positioned where the volume markings on the bag will sit. Cut a piece of clear vinyl (available at any fabric store) about an inch larger than the opening on all sides. Pin it behind the opening, fold the raw fabric edges inward about half an inch, and topstitch through both the fabric and vinyl. The result is a neat window that lets you monitor output at a glance.
If sewing through vinyl feels tricky, place a piece of tissue paper between the vinyl and your presser foot to prevent sticking, then tear the paper away after stitching.
Attachment Options
How the cover stays in place depends on where the bag is worn.
Leg Bags
Most leg bags are already held in place with straps around the thigh or calf. The simplest approach is to let the cover hang loosely over the bag, secured only by the drawstring cinched around the tubing at the top. If you want something more secure, sew two small fabric loops onto the back of the cover, spaced to match the leg straps. The straps thread through the loops, holding the cover snug against the leg.
Wheelchair or Bed Frames
For bags that hang from a wheelchair or bed rail, sew a fabric strap or pair of ties near the top of the cover so it can loop over the frame. Velcro closures work well here because they’re easy to open and close one-handed. Sew a strip of hook-and-loop tape to a fabric strap, wrap it around the rail, and press closed. Buttons are another option but require two-handed dexterity that not every user has.
Making It Washable and Durable
Catheter bag covers should be washed frequently since they’re in regular contact with medical equipment. Having two or three covers in rotation means one is always clean and ready.
Finish all raw seams to prevent fraying over repeated washes. You can use a zigzag stitch along the raw edges, pink the edges with pinking shears, or use a serger if you have one. French seams (enclosing the raw edge inside a double fold of fabric) are the most durable option and keep the inside of the pouch neat.
Reinforce the drawstring casing with a second line of stitching, since this area gets the most stress from repeated opening and closing. If you used a cotton drawstring cord, expect it to shrink slightly in the first wash, so cut it a few inches longer than you think you need.
Customization Ideas
The whole point of a handmade cover is that it doesn’t look medical. Choosing a fabric pattern the user loves transforms a clinical accessory into something that feels more like a personal item. Some people make covers to match specific outfits or seasons. For children, novelty prints featuring favorite characters can make the experience less intimidating.
Appliqué, embroidery, or iron-on patches add personality without affecting function. Just keep embellishments on the outer surface so nothing rough presses against the bag itself. If you’re making covers as a gift or donation, neutral patterns in darker colors tend to be the most universally appreciated, since they hide any discoloration over time and suit a range of personal styles.
For tubing, you can sew a simple fabric sleeve from a strip about 3 inches wide and as long as the exposed tube. Fold it in half lengthwise, sew along the long edge, turn it right side out, and slip the tubing through. This hides the tubing between the bag and the connection point, completing the coverage.
