Spa Covers
Better protection. Better heat retention. A better fit for your spa.
Whether you need a traditional replacement cover, a premium WeatherShield cover or a Smartop system, Blackthorne can help you find the right cover for your hot tub.
Choose the Cover That Fits How You Use Your Spa
From traditional insulated covers to lightweight performance fabrics and fully integrated rigid-cover systems, Blackthorne offers several ways to protect your spa.
Smartop
Smartop eliminates one of the biggest frustrations associated with traditional foam spa covers: waterlogging. Its rigid construction is designed to stay lightweight instead of becoming heavier as the cover ages.
No Waterlogging
Traditional foam spa covers can absorb moisture over time, making them increasingly heavy and difficult to handle. Smartop uses a rigid cover design that does not absorb water like traditional foam-core covers.
No moisture-soaked foam core getting heavier over time.
Cover and lifting system are designed to work together.
A premium alternative to a traditional foam spa cover.
Vanish XL
A low-profile system designed to place the open cover behind the spa while preserving your view.
Upright 3.0
Opens vertically behind the spa, creating a convenient privacy and wind screen.
Swim Spa
Smartop technology scaled for swim spas with integrated lift assistance for easier opening and closing.
WeatherShield Covers
A modern alternative to traditional marine-grade vinyl.
WeatherShield is a solution-dyed polyester cover material designed to be lightweight, durable and resistant to water absorption.
Reduction in overall cover weight
Stronger than traditional vinyl
Superior tear and abrasion resistance
Made with recyclable materials

Your Spa Cover Shouldn't Be a Guess
