231" x 94" Swim Spa Cover for H2X Trainer 19 and MP Momentum

The 231" x 94" Master Spas® OEM swim spa replacement cover is built to fit H2X Trainer 19 and Michael Phelps Momentum swim spas. Designed for performance and durability, this factory-original cover features thick foam insulation that tapers from 6" in the center to 4" along the sides—helping retain heat and reduce energy loss.

With marine-grade vinyl, a reinforced bottom, and locking safety hardware, this replacement cover protects your spa from the elements while keeping it energy efficient and secure.

Please note that the custom covers we produce feature split corners on the skirt, meaning the vinyl skirt panels meet at each corner rather than wrapping continuously. If you're replacing an older cover with fully rounded skirt corners, you'll notice this difference upon arrival of your custom cover.

Highlights of the 231" x 94" replacement cover include:

• EPS Foam Cores with Taper – 6" thick insulation at the center tapers to 4" at the edges, with a 1.5 lb foam density to reduce moisture intrusion and prevent heat loss.
• Full-Length Heat Seal – Helps lock in heat along the fold; the outer vinyl scrim is chemically resistant and weighs 12 oz.
• Three-Panel Skirt Design – Surrounds the cover edge to block debris and enhance insulation.
• Upgraded Rubber Grip Handles – More durable and comfortable than standard handles for easier lifting and repositioning.
• Four Release/Lock Hardware Connections – Built-in locking straps keep your cover secure during rough weather.
• Galvanized Steel Brackets – Provide enhanced structural integrity and long-term strength.
• Reinforced Bottom Vinyl – The 11 oz mildew-treated weft is built to last, even in damp environments.
• Double-Stitched Seams – 27 reinforced stress points for years of reliable use.
• ASTM Compliant – Meets safety standards for spa covers.
• 18 Color Options – Available in a variety of colors to match your spa; see photo options above.
