Smartline 12×20 Rectangle Beaded Liner Boulder Swirl 4 ft Flat Bottom

This Smartline 12 ft x 20 ft rectangle swimming pool liner features a boulder swirl design and is tailored for kayak pools with a flat bottom measuring 4 feet deep. Constructed from 20 gauge heavy-duty virgin vinyl, it offers solid durability. The beaded style liner snaps securely into the bead receiver opening, simplifying installation.
Notable features include material cut and hand-folded in North America to reduce creasing and wrinkles. Installation is recommended during moderate temperatures (70-80 degrees Fahrenheit), and pre-warming the vinyl in sunlight improves flexibility for a better fit. Always verify pool wall height is accurately measured before purchase to ensure proper fit.
Smartline 12×20 Rectangle Beaded Liner Mystri Gold 4 ft Flat Bottom

The Mystri Gold design model from Smartline upgrades the liner gauge to 25 gauge heavy-duty virgin vinyl, adding enhanced toughness and longevity. It shares the same beaded style and 4-foot flat bottom design ideal for kayak pools of the specified size.
Manufacturing details include a hand-folded liner to minimize creases and recommended installation temperature windows. The beaded edge design facilitates a firm and secure fit into your pool’s bead receiver. Proper measurement of height and footprint before ordering remains critical to ensure compatibility.
Smartline 12×20 Rectangle Beaded Liner Boulder Swirl 5.5 ft Deep End

This variation of the boulder swirl liner is designed for pools with a 5.5-foot deep end instead of a flat bottom, also made with 25 gauge vinyl for superior resilience. The beaded style remains consistent, allowing easy snap-in installation and reliable hold.
It’s well-suited for kayak pools that require variable depth. Similar installation tips apply, such as warming the material and double-checking measurements to optimize stretch and fit. Its heavy-duty vinyl withstands outdoor exposure and normal wear.
Coping Kit for 12×20 Kayak Pools, 1¼ Inch x 8 ft Sections

The SMOPS coping kit contains eight 8-foot long sections of vinyl coping designed to snap onto the top rails of 12 by 20-foot kayak pools. This replacement kit is ideal for pools made between 1977 and 2000 needing restoration of cracked or yellowed coping pieces.
Though the coping does not support the liner structurally, it provides a polished finish where the liner snaps into the liner channel. The kit leads to easy installation and improved aesthetics, rejuvenating older pool setups.
Liner Life 12×20 Above Ground Pool Liner Pad Polyester Geotextile

This Liner Life pre-cut pool liner pad offers an essential layer of protection between your kayak pool liner and the ground. Made from durable polyester geotextile material, it guards against punctures caused by rocks, roots, and debris.
The pad is designed to fit common aboveground pools including rectangles measuring 12 by 20 feet. Its simple installation eliminates tedious measuring or cutting, and it also helps prevent sand base imprints called “footprints,” improving liner lifespan and comfort.
Buying Guide: Key Considerations for 12×20 Kayak Pool Liners
When selecting a kayak pool liner sized 12 feet by 20 feet, several factors impact your purchase choice and overall satisfaction:
Material Thickness and Durability
Vinyl gauge thickness affects liner strength and puncture resistance. Common options include 20 and 25 gauge. Heavier 25-gauge liners are more durable in rugged conditions and last longer, justifying the investment.
Pool Bottom Type and Depth
Confirm whether your pool has a flat bottom or includes a deep end. Liners come in flat-bottom styles (typically 4 feet) or models with varying depth (e.g., 5.5 feet) for proper fit and water volume management.
Liner Style: Beaded vs. Overlap
Beaded liners snap into a bead receiver track on the pool wall, providing a secure fit suitable for many kayak pool types. Overlap liners drape over the pool walls and secure under coping strips, easier to replace but potentially less snug.
Installation Environment
Optimal installation temperatures between 70 and 80 degrees Fahrenheit help vinyl stretch properly and avoid wrinkles. Pre-warming the liner in sunlight is recommended by manufacturers.
Protection Pads and Accessories
Consider purchasing a liner pad to place beneath the liner. Puncture-resistant pads shield the liner from sharp objects and uneven ground. Replacement coping kits can restore the top edge finish of older pools.
Compatibility and Measurements
Accurate pool measurements including length, width, and wall height are crucial. Incorrect sizing results in poor fit, wrinkles, or liner damage. Verify whether the liner fits your specific kayak pool model and manufacturer guidelines.
