Free Knitting Pattern: Banguibain Rug or Bath Mat

There is something deeply satisfying about making something useful for your home with your own hands. A rug or bath mat is one of those projects that gets touched every single day — stepped on, stood on, admired — and knowing you made it yourself adds a quiet pride to even the most ordinary morning routine. The Banguibain Rug or Bath Mat is one of those patterns that manages to be both beginner-friendly and genuinely beautiful, the kind of project that looks far more complicated than it actually is. Whether you want a soft landing for bare feet beside the tub, a welcoming doormat for a guest room, or a cozy accent piece for a reading nook, this pattern adapts beautifully to your space and your yarn stash.

This free knitting pattern walks you through every step of the process, from choosing your materials to casting off the final stitch. Read through the whole thing before you begin — not because it is difficult, but because knitters who take five minutes to preview a pattern before picking up their needles almost always have a smoother, more enjoyable experience.

Why Knit a Rug or Bath Mat?

Before we get into the pattern itself, it is worth talking about why a hand-knitted rug or bath mat is such a rewarding project. Purchased bath mats are almost universally disappointing. They flatten quickly, the rubber backing cracks, the color fades after a handful of washes, and they never quite feel as plush as they looked on the shelf. A knitted bath mat, on the other hand, gets better with washing. The fibers bloom and soften, the texture becomes more pronounced, and because you chose the yarn yourself, the colors stay true to your vision.

Rugs and bath mats also make exceptional gifts. They are practical in a way that a decorative item is not, and the handmade quality is immediately apparent to anyone who uses one. A knitted bath mat for a housewarming, a wedding, or a new baby’s nursery is the kind of gift people keep for years and genuinely use rather than store in a closet.

From a craft perspective, rug knitting is also a wonderful way to build skills. The projects are worked in simple, repetitive stitch patterns that let your hands find a rhythm while your mind relaxes. If you are a beginner, a rug or bath mat lets you practice tension and consistency over a large surface without the pressure of shaping. If you are an experienced knitter, it gives you a meditative, low-stakes project to pick up between more complex works.

About the Banguibain Pattern

The Banguibain pattern takes its name from the Scots Gaelic word for “bath,” reflecting the simple, honest purpose of the piece. It is designed to produce a dense, tightly knitted fabric that holds up well underfoot, dries quickly after bathroom use, and provides just enough cushioning to make standing comfortable. The stitch pattern is a modified seed stitch combined with garter rows, which creates a bumpy, textured surface that is beautiful, functional, and non-slip when backed with a rug pad or fabric backing.

The pattern is written for a standard bath mat size of approximately 20 inches wide by 30 inches long, but instructions for resizing are included below. The gauge is intentionally forgiving — this is a project where a slight difference in tension will only affect the final dimensions, not the appearance or structure of the piece.

Materials You Will Need

Yarn: Approximately 400 to 500 yards of a bulky or super bulky cotton or cotton-blend yarn. Cotton is the traditional choice for bath mats because it is absorbent, durable, machine washable, and does not hold moisture against the skin the way synthetics can. Look for a yarn labeled “bulky” (weight 5) or “super bulky” (weight 6). Recycled cotton, organic cotton, or a cotton-acrylic blend all work beautifully. Avoid wool for a bath mat that will be regularly wet — wool felts and shrinks with washing. For a bedroom rug, wool is a wonderful option and adds warmth and resilience.

Needles: US size 10 (6mm) circular needles or straight needles, 24 inches long if circular. Circular needles are recommended even for flat knitting because the weight of the piece distributes better along the cord as your project grows.

Other supplies: Tapestry needle for weaving in ends, scissors, measuring tape, stitch markers (optional but helpful), and a rug pad or non-slip backing material if desired.

Gauge

With bulky cotton yarn on size 10 needles:

12 stitches and 18 rows = 4 inches in seed stitch pattern, blocked.

Gauge is not critical for this project, but checking it before you begin will help you estimate yarn quantity accurately and predict your finished dimensions. If your gauge is looser than stated, your mat will be larger and you may need more yarn. If your gauge is tighter, your mat will be smaller and denser.

Garter Stitch: Knit every row.

Pattern Instructions

Cast On

Using the long-tail cast on method, CO 60 stitches. The long-tail cast on creates a firm, tidy edge that holds its shape well and lies flat against the floor, which is exactly what you want for the bottom edge of a mat.

If you want a narrower or wider mat, cast on any multiple of 2 stitches. Adding or removing 10 stitches will change the width by approximately 3 to 3.5 inches depending on your gauge.

Garter Border (Bottom Edge)

Rows 1–6: Knit every stitch across every row. This creates a garter stitch border of 3 ridges on the right side. The border serves a practical purpose — it prevents the edges from curling and gives the mat a clean, finished look without any additional finishing work.

Main Body

The body of the Banguibain mat is worked in a combination of seed stitch panels and garter stripe rows. This pattern creates a gorgeous, tactile texture that looks woven when finished.

Setup Row (RS): K4 (border), pm if desired, work in seed stitch to last 4 sts, pm if desired, K4 (border).

The 4 knit stitches on each end form a garter stitch border running up both sides of the mat, just as the garter rows do at the top and bottom. This means all four edges are bordered in the same texture, creating a cohesive, polished look.

Continue as follows:

Rows 1–10: K4, work seed stitch to last 4 sts, K4.

Row 11 (Garter Stripe): Knit all stitches across.
Row 12 (Garter Stripe): Knit all stitches across.

These two rows together create one garter ridge on the right side of the work, which acts as a visual break between sections of seed stitch.

Rep this 12-row sequence until the mat measures approximately 28 inches from the cast-on edge, or until you have reached your desired length minus the top border.

For a mat that is approximately 30 inches long, you will work the 12-row sequence approximately 7 to 8 times, depending on your gauge. Measure frequently rather than counting rows alone, as yarn and tension can vary.

Garter Border (Top Edge)

Rows 1–6: Knit every stitch across every row. This mirrors the bottom border and completes the mat.

Bind Off

Bind off all stitches loosely using a standard knit bind off. Binding off loosely is important — a tight bind off on a mat will cause the top edge to pucker and pull. If you tend to bind off tightly, try going up one needle size for the bind off row only.

Finishing

Cut your yarn, leaving a tail of approximately 8 inches. Thread your tapestry needle and weave in all ends thoroughly. For a bath mat that will be washed frequently, weave each end in at least two directions, doubling back on itself, to ensure the ends stay secure through repeated laundering.

Wet Blocking

Wet blocking is highly recommended for cotton bath mats and rugs. Soak your finished mat in cool water for 20 to 30 minutes, then gently press out excess water — do not wring or twist. Lay the mat flat on a clean towel, roll the towel and mat together, and press firmly to remove more water. Unroll, lay the mat flat on a dry surface, and shape it to your desired dimensions. Allow to dry completely before use. Cotton blocking is dramatic — your mat will open up, soften, and gain an inch or two in both directions as the fibers relax.

Non-Slip Backing (Optional but Recommended)

For safety, particularly on tile or wood floors, adding a non-slip backing to your mat is a good idea. You have several options. The simplest is to purchase a roll of rug pad material from a home goods store and cut it to size, then place it under the mat. Alternatively, you can purchase iron-on rug backing or liquid latex backing and apply it directly to the wrong side of the mat. A third option is to sew a piece of non-slip fabric to the wrong side using a tapestry needle and yarn.

Resizing the Pattern

One of the best things about this pattern is how easy it is to adjust. Here is a quick guide to resizing for different applications.

For a small hand towel mat or toilet rug, cast on 36 stitches and work until the piece measures about 20 inches. This uses approximately 200 yards of yarn.

For a standard bath mat, follow the pattern as written for a 20 by 30 inch mat using approximately 400 to 500 yards.

For a larger bathroom rug or entry rug, cast on 90 stitches and work until the piece measures 36 inches. You will need approximately 800 to 900 yards of yarn, potentially two skeins depending on skein size.

For a full-size accent rug, cast on 120 stitches and work to your desired length. At this scale, you may want to work with two strands of a worsted weight cotton held together rather than a single strand of bulky, which gives you more color flexibility.

Yarn Suggestions and Color Ideas

Choosing the right yarn makes a significant difference in the final result. For bath mats and rugs, here are some characteristics to look for: machine washability (essential for anything going in the bathroom), durability, low stretch, and good stitch definition.

Some excellent yarns for this pattern include Lion Brand 24/7 Cotton, which is widely available, affordable, machine washable, and comes in a generous range of colors. Paintbox Yarns Simply Chunky Cotton is another popular choice, particularly for knitters in the UK and Europe. For an elevated option, Loome Chunky Tube Yarn creates a particularly plush and absorbent fabric. If you are in a yarn shop and uncertain, bring this pattern and ask for a machine-washable cotton or cotton-blend in a bulky weight — most yarn shop staff will be able to point you in the right direction immediately.

For color, solid colors show off the texture of the seed stitch beautifully. Crisp white, warm ivory, and soft gray are perennial favorites for bathroom mats. If you want something more vibrant, consider a deep navy, a sage green, or a terracotta — all are trending in home décor and look stunning against tile. If you want to experiment with color without committing to striping on your first attempt, self-striping or gradient cotton yarns create interesting color progressions with no extra effort.

Tips for Success

Tension consistency matters more than gauge precision in a rug or mat. Try to knit at a consistent pace, especially if you are a knitter who tends to knit tighter when distracted or tired. If you notice your stitches getting tighter partway through, take a break and come back fresh.

Use a needle with a good cable if you are using circulars. The weight of a growing rug can strain poor-quality cables and cause them to kink or separate, which is frustrating at best and project-ending at worst. Brands like Chiaogoo, Addi, and Knitter’s Pride make cables that handle the weight of dense cotton knitting very well.

If you are knitting for a bathroom with specific dimensions, measure your space before you cast on. There is nothing worse than finishing a beautiful bath mat only to discover it does not fit the space you made it for. Measure the area in front of your tub or shower, subtract a few inches of clearance on each side, and use those measurements to guide your cast on count and target length.

Keep your yarn in a bowl or bag beside you as you knit. Bulky cotton can be surprisingly heavy, and a ball bouncing across the floor tends to pick up dust and debris — particularly undesirable for something that will be living in a bathroom or entryway.

Caring for Your Knitted Mat

Machine wash your Banguibain mat in cold water on a gentle cycle. Avoid hot water, which can cause cotton to shrink. Do not use bleach, even on white or light-colored mats, as bleach weakens cotton fibers over time. Tumble dry on low or lay flat to dry. The mat may need a gentle re-blocking after the first few washes, but will become more stable and relaxed with each laundering.

With proper care, a well-made knitted cotton rug or bath mat will last for many years. It is the kind of project you finish once and enjoy every single day for a long time after — which makes every stitch worth it.

Share Your Make

If you knit the Banguibain Rug or Bath Mat, share your finished piece on Instagram or Ravelry with the tag #BanguibainMat so other knitters can see your version, your color choices, and your creativity. Nothing inspires other knitters more than seeing a beloved pattern made in a hundred different ways by a hundred different hands. Your yarn choices, your finishing touches, and your own bathroom floor all make this pattern yours in a way that no two finished mats are ever quite the same.

Happy knitting, and enjoy every step you take on your finished mat.
