Our regular shower curtain (for use with a tub) measures 75" wide. (We also offer a shower stall curtain for walk-in showers which measures 50" wide. ) The fabric is only available in a 54" width so our shower curtain does have seams. We've chosen to use the full fabric width in the center and 2 panels of equal width on either side for balance. The pattern is matched. We offer the shower curtain lined or unlined. The lining is a cotton sateen lining and doesn't take the place of a plastic, water-resistant liner. It's used to hide the seams and add body to the fabric. We sell many unlined shower curtains, too. We'd be happy to send you a fabric sample if you'd like. Just send us your name and mailing address. Thanks for your interest!
