Well-made liner that ‘s heavy & durable
Size: 72"W x 78"L (Pack of 1), Color: 1a. Clear
These Barossa Design Long Shower Curtain Liner is thick, sturdy, and looks and feels noticeably more durable than standard liners. The heavier weight helps it hang straight without clinging, giving the shower a clean, polished look.
It does a great job keeping water contained, and the material feels strong enough to last through regular use without tearing or thinning out. The length is ideal for taller showers, adding extra coverage and protection.

Great Quality and Perfect for Creative Projector Effects
Size: 72"W x 72"L (Pack of 1), Color: 1a. Clear
Although designed as a shower curtain liner, I ended up using this for a completely different purpose and it worked perfectly.
I placed it behind my study window as a projection screen for Halloween videos, and the results were fantastic. The material allowed the projector image to display clearly while still diffusing the light nicely for a great effect from outside.
The quality was much better than expected, the material felt durable, and it was easy to position and work with.
This product turned out to be incredibly versatile and offered excellent value for the money. If you enjoy creative decorating ideas or seasonal displays, this works brilliantly as an inexpensive projection screen alternative.

Perfect length and actually stays in place.
Size: 72"W x 75"L (Pack of 1), Color: 1a. Clear
This liner solved a problem I didn’t realize was bothering me until I switched to it. The extra length makes a big difference—no more water sneaking out onto the floor or the curtain riding up while you’re showering. It hangs nicely and gives a cleaner, more finished look compared to standard sizes.
The material feels thicker than the cheap liners you usually find, but not overly stiff. It drapes well and doesn’t stick to you while showering, which is a big plus. The magnets at the bottom actually work and help keep it in place against the tub, especially if you have any airflow in the bathroom.
Installation was simple and the reinforced holes seem durable enough to last. Overall, it just does what it’s supposed to do without any fuss. For the price, it’s a solid upgrade and something I’d definitely buy again.

Well made
Size: 72"W x 72"L (Pack of 1), Color: 1b. Clear-heavy
The magnets hold well. The grommets are sturdy. The plastic is a bit thick and doesn't like to lie flat against the tub so it is constantly brushing you while you shower.

Great disposable shower liner
Size: 72"W x 72"L (Pack of 1), Color: 1a. Clear
Didn't expect much from a shower liner, but this one delivered. The clear PEVA material looks clean and modern, and there's none of that gross chemical smell you get with cheap PVC liners.
The three bottom magnets are a game-changer — no more liner blowing into you mid-shower. Rustproof grommets mean no rust stains either.
Maintenance is a breeze: quick rinse, dries fast, done. Great value for what you get. Would recommend.
