Best Sea Glass Pool Liners for Above-Ground Pools
The best sea glass pool liner depends on your pool’s diameter, wall height, and installation style. These five Cracked Glass overlap liners offer a blue mosaic look, with options for 15-, 18-, and 24-foot round pools. Smartline models are described as hand-folded and intended for flat-bottom pools with 48- or 52-inch walls; Swimline models specify 25-gauge vinyl and reinforced seams. Measure your pool before choosing, and confirm that an overlap liner fits its construction.

Smartline 18-Foot Cracked Glass Liner
Best for: Owners of an 18-foot round above-ground pool with a flat bottom and a 48- or 52-inch wall. The Cracked Glass pattern adds a blue mosaic detail around the pool, while the listing describes the liner material as hand-folded to help prevent permanent creases and excess wrinkling.
This is an overlap liner: it drapes over the pool wall and is held with coping strips. The listing says bead receivers are not needed. Before installation, measure the pool diameter from wall to wall through the center and check the wall height from the ground to underneath the top rail.
Limitation: This liner is not intended for Intex or pop-up pools. Its stated fit is limited to flat-bottom pools with 48- or 52-inch walls.
Swimline 15-Foot Cracked Glass Liner
Best for: Buyers with a 15-foot round above-ground pool who want a liner with stated material and seam details. Swimline describes this model as 25-gauge, 100% virgin heavy-duty vinyl, with reinforced seams and LAMICLEAR UV inhibitors. The listing also says its coating is designed to resist pool chemicals, fading, tearing, and punctures.
The overlap design folds over the pool wall and uses coping strips, which are sold separately. The product listing says a bead receiver is not required and describes the liner as suitable for metal or resin frames. Choose this option if those details match your pool and you want the manufacturer-stated UV and seam features.
Limitation: The supplied product details do not specify the compatible wall height or bottom shape. Confirm those dimensions and fit with the seller before buying.
Smartline 15-Foot Cracked Glass Liner
Best for: Owners of a 15-foot round pool with a flat bottom and 48- or 52-inch walls. This Smartline option features the blue Cracked Glass mosaic and a hand-folded cut intended to reduce permanent creasing and excess wrinkling.
The overlap installation places the liner over the pool wall and secures it with coping strips; the listing says bead receivers are unnecessary. Smartline recommends laying the liner in the sun for at least an hour before installation so the vinyl can warm and stretch as water is added. It also identifies 70–80°F as the preferred installation temperature range.
Limitation: It will not work with Intex or pop-up pools. Check the pool’s measured diameter and wall height rather than relying only on the model name.
Smartline 24-Foot Cracked Glass Liner
Best for: A 24-foot round pool that has a flat bottom and 48- or 52-inch walls. The listing describes the Cracked Glass design as a blue mosaic and says the rolling-water appearance on the floor can create a nearly bottomless look.
This is an overlap model secured with coping strips, with no bead receiver needed according to the product details. Its North American cut material is hand-folded. For installation, Smartline advises warming the liner in the sun for at least an hour and recommends working in temperatures of 70–80°F. Choose it if those installation and pool specifications fit your project.
Limitation: The listing excludes Intex and pop-up pools. It is not described for other wall heights or pool bottoms.
Swimline 24-Foot Cracked Glass Liner
Best for: Owners of a 24-foot round above-ground pool seeking a liner with listed vinyl, seam, and coating specifications. Swimline identifies this as a 25-gauge liner made from 100% virgin heavy-duty vinyl. It also lists reinforced seams and a chemical-resistant coating, along with UV, fade, and tear resistance.
The overlap style folds over the wall and is secured with coping strips, which are sold separately. The listing says a bead receiver is not required and names metal or resin frames as suitable. Compared with the Smartline 24-foot option, this product emphasizes its stated 25-gauge material and reinforced seams.
Limitation: The provided details do not state the compatible wall height or bottom shape. Verify the exact fit for your pool before ordering.
Buying Guide: How to Choose a Sea Glass Pool Liner
How do you measure for the right size?
For a round pool, measure from one inside wall to the opposite wall through the center to determine diameter. Measure wall height from the ground to the underside of the top rail. Match both measurements to the liner listing. A diameter that is close but not exact is not a substitute for confirming the stated pool size.
What does overlap installation mean?
An overlap liner drapes over the pool wall and is secured with coping strips. The Smartline listings say bead receivers are not needed, while Swimline says coping strips are sold separately. Check your existing pool setup and confirm that an overlap liner is appropriate before purchase.
Which material details should you compare?
Smartline emphasizes hand-folded material and gives installation preparation guidance. Swimline lists 25-gauge, 100% virgin heavy-duty vinyl, reinforced seams, and UV inhibitors. These are product-listing specifications, not a direct comparative test. Choose based on the features stated for the exact size you need.
What should you check before installing?
Confirm the pool’s bottom shape, wall height, frame type, and liner diameter. Smartline specifies flat-bottom pools with 48- or 52-inch walls and excludes Intex and pop-up pools. For its liners, the listing recommends warming the vinyl in sunlight for at least an hour and installing in 70–80°F conditions.
Frequently Asked Questions
Is Cracked Glass the same as a sea glass pattern?
The products listed here use the name Cracked Glass. Their descriptions identify a blue glass-piece mosaic design; they are not specifically labeled “sea glass.”
Do these liners fit Intex pools?
The Smartline listings explicitly say they will not work with Intex or pop-up pools. The supplied Swimline details do not confirm Intex compatibility, so verify fit before buying.
Are coping strips included?
The Swimline listings say coping strips are sold separately. Smartline describes using coping strips but does not state whether they are included.
Can I use a 48-inch liner on a 52-inch wall?
Do not assume the sizes are interchangeable. Check the specific listing and measure your pool’s wall height before selecting a liner.
What is the main difference between the 15- and 24-foot options?
The primary stated difference is the pool diameter each liner is designed for. Select the size that matches your measured round pool, then compare material details and fit requirements.
