ColourTree Custom Size 11ft x 18ft Blue Waterproof Sun Shade Sail

In this review the ColourTree Custom Size 11' x 18' Blue TADR0712 shade sail is judged as a practical, heavy-duty canopy option for homeowners and small businesses who need reliable sun and rain protection. The biggest reason to consider it is the combination of a dense 220 GSM virgin polyethylene fabric with a waterproof coating and reinforced corners, which together deliver both effective UV blocking and water resistance. For anyone wanting a customizable, long-lasting patio or carport shelter, this sail offers proven functionality backed by a three year limited warranty.

Key Features

• 220 GSM virgin fabric: The thick non-recycled polyethylene provides robust tear resistance and a solid feel that holds shape under tension.
• Waterproof coating: A sealed layer prevents water penetration so the sail sheds rain and keeps the area underneath dry.
• UPF50 and UV treatment: Commercial grade UV resistant treatment helps the canopy block sunlight and reduce heat beneath the sail.
• 316 stainless D-rings: Premium grade D-rings at each corner make attachment straightforward and corrosion resistant for outdoor installation.
• Double reinforced seams: All edges are double stitched to reduce fraying and distribute pulling forces from anchor points.
• Three year warranty: A limited three year warranty offers free replacement if the product does not meet expectations.

Who It's For

This shade sail is best for homeowners with patios, decks, small carports or backyard play areas who want a durable, waterproof canopy that also blocks UV. It suits people who prefer a fixed, sewn product over lightweight mesh sails or pop-up umbrellas and who plan to install it with secure anchors.

Those who need a very large engineered structure for commercial use or who require a fully custom-fabricated tension system should look elsewhere; the sail is ideal for residential and light commercial outdoor shading but not intended as a structural roof replacement.

Pros & Cons

Pros

• High fabric weight and UV finish deliver strong shade and heat reduction without feeling flimsy.
• Waterproof coating means it functions as both a sun sail and a light rain canopy, keeping surfaces dry beneath.
• 316 stainless steel D-rings and reinforced stitching improve long-term durability and ease of installation.
• The three year limited warranty provides reassurance and an option for replacement if there are defects.

Cons

• The sail requires correct tensioning and secure anchors for best performance, so casual buyers may need basic hardware and some installation effort.
• Color and sizing are customizable but buyers should confirm measurements carefully to ensure the 11' x 18' fit matches their layout.
