A crochet toilet seat cover is a fitted decorative piece, popular as a retro bathroom accent, that stretches over the lid using an elastic backing sewn into the edge to hold it securely in place. I made a set of these in a coordinating color for a bathroom refresh a few years back, and they held up far better than I expected once I got the elastic backing right. This guide covers materials, the full pattern, and how to attach the elastic for a secure, non-slip fit.
Materials Needed
- About 150 yards worsted weight yarn
- A 5.0mm hook
- About 24 inches of 1/4 inch elastic
- A sewing needle and matching thread for attaching the elastic
Pattern Instructions
- Trace the shape of your specific toilet lid onto paper to use as a sizing guide, since lid shapes vary between standard round and elongated models.
- Chain 2, work 8 sc into the second chain from the hook, closing the ring.
- Increase each round following a standard circle count, but shape the increases unevenly to match your traced oval or teardrop shape rather than a perfect circle, adding extra stitches at the wider end and fewer at the narrower end.
- Continue increasing until the piece matches your traced pattern’s full size, checking against the paper template every few rounds.
- Work one final round of single crochet around the entire outer edge for a clean, finished border.
Attaching the Elastic Backing
- Cut a length of 1/4 inch elastic about 2 inches shorter than the finished piece’s outer edge measurement, so it stretches slightly once sewn on.
- Pin the elastic to the wrong side of the crochet piece, just inside the outer edge, stretching it gently as you pin to distribute it evenly around the curve.
- Sew the elastic in place by hand, using a simple running stitch through both the elastic and the crochet fabric, working in small sections to keep the stretch even.
- Test the fit on your actual toilet lid, adjusting the elastic tension slightly if the cover feels too loose or too tight.
Sizing Tips
Standard round lids and elongated lids differ enough in shape that a single universal pattern will not fit both well. Always trace your specific lid before starting, since even standard round lids vary in exact diameter between manufacturers by an inch or more.
Style and Color Options
A solid single-color cover reads as the most classic vintage look, but a simple two-round color change near the outer border adds a decorative accent without complicating the pattern’s shaping. I have also seen striped versions worked in concentric color rings from the center outward, which works with this same construction as long as the color switches happen at the start or end of a round for a clean transition.
Matching a set of two or three coordinated bathroom accessories, like a tank lid cover and a tissue box cover, in the same color and stitch pattern creates a cohesive retro bathroom theme rather than a single standalone piece.
Fitting Elongated vs. Round Lids
Elongated lids, more common on modern toilets, need extra length added at the front point of the traced shape compared to a standard round lid. When shaping the increase rounds for an elongated pattern, add slightly more stitches at the front and back points and fewer at the sides, mimicking the traced oval outline rather than following a perfectly even circular increase count.
Elastic backing is the most reliable way to keep the cover secure, since a plain flat crochet piece alone tends to slide around with regular use. Sewing in a stretched elastic band around the underside edge holds the shape snugly against the lid.
