The Liner
A detachable inner liner connects along a hidden snap track. Unclip it, machine wash cold, clip it back. The shower stays fresh — the chore disappears.

A quieter kind of upgrade
The liner now snaps out, washes in your machine, and snaps back in seconds. The hooks are gone. The fabric is heavier. The result feels less like a curtain — more like a quiet upgrade to the room.

Good to know
Yes. Ostera is designed to fit all standard shower rods up to 1.5 inches in diameter — straight, curved, or tension-mounted. The integrated flex-rings glide on without any hooks or hardware.
Unsnap the inner liner from the outer curtain, machine wash cold on a gentle cycle, and tumble dry low or hang to dry. Snap it back in when it's ready. We recommend washing every two to three weeks.
Only the top panel is sheer, which lets natural light into the shower without compromising privacy. The main body of the curtain is fully opaque heavyweight waffle weave.
The standard size is 71" wide × 74" tall, designed to fit virtually all North American tubs and most walk-in showers. The liner is matched to the same dimensions.
Try Ostera risk-free for 30 days. If it isn't right for your bathroom, send it back for a full refund — no questions, no restocking fees.
