Trifold spa cover is a rectangular 3 Panel cover and is made with 4"-2" tapered foam.   This is the upgraded tri-fold cover with thicker 4mil vapor barrier and robust aluminum channeling (not the cheaper galvanized channeling), double topstitch workmanship (not the cheaper single topstitch). 
This cover type is the premium cover.  We do not offer the cheaper covers as better materials and workmanship holds up longer and should be the only way these spa covers are offered.

The tri-fold covers already include the 1.5" denser foam.  We recommend upgrading to the thicker 2" foam density if you live in a northern climate.

Free Shipping on this spa cover anywhere in the USA except Hawaii or Alaska.

The tri-fold cover comes with up to 8 tie down straps that have key lock fasteners.  This durable spa cover is made with galvanized channeling and has steam stoppers included to help prevent heat from escaping.  Upgrade to the rubber handles for more durability.

Allow appx. 4-6 weeks for cover production and about a week for shipping depending on your location.  (Production time has increased due to challenges caused by the pandemic.)  You will be contacted by shipper at the phone number you provide at checkout to arrange delivery.

Additional Straps
Up to 8 straps are included with the trifold cover.

Covers include 2 standard handles. Can upgrade to rubber handles or add additional handles as needed.
Gazebo handles are only for the fold area and are not commonly used - Gazebo handles are a pair of handles under the fold where a fold is present.

Contact us for custom covers over 102 inches in length. We also can make a walk-on 6-4 trifold cover in any size up to 102" large. For larger trifold covers, contact us with your dimensions for 3 individual walk-on cover sections with 3lb. foam cores and 6 inches thick and flat. (Get quote with your dimensions over 102 inches at or give us a call).  Trifold covers are non-returnable/non-refundable as they are custom made to your specifications and dimensions.

note: cover manufacturer no longer offers velcro to connect the overflap as that stresses the cover material and voids the warranty. Over-flap style butts up flat against the next panel with a decorative flap over top of the joint.

Standard Fold - the "A" or first dimension given is the one that gets cut in half to create the fold.
Standard Fold always goes across the shorter side/dimension as shown above for rectangular covers. If a "reverse fold" is desired (folding across the long dimension - hot dog bun fold style) - you must specify REVERSE FOLD in order detail box above along with putting the smaller dimension as the "A" or first dimension given.

Free shipping is offered to most destinations in the continental USA. In the case the delivery address is outside shipper's normal delivery area, you will be contacted prior to production.

Covers are not available for international shipment, nor to Canada, Alaska or Hawaii.

    Best Trifold Hot Tub Cover

    Posted by Unknown on 24th Jul 2018

    I am very pleased with the product. The tri-fold hot tub cover allows a single person to remove or cover the hot tub. Due to our cramped enclosure where our hot tub is located this trifold hot tub cover is a perfect fit for our needs. We are using the single detachable panel and stitched 2 panel configuration. I would recommend this for anyone with a hot tub with a low hanging ceiling like ours.

    Tri-Fold hot tub cover

    Posted by Michelle Carr on 14th Jun 2018

    Cover fits great, color doesn't look like the color shown, way more red then we would of liked and also took a long time to get to us. Overall, great fit though and easy to fold back.

    Exactly as ordered and presented on website

    Posted by Ralf on 19th Jun 2017

    received the cover, delivery was friendly and nice with advance calls to schedule a pretty exact time of deliver, so I could be at home to receive it. Delivery was great and driver brought it all the way to my backyard. cover is exactly as expected, the tri-fold is great for our hot tub as it is enclosed in a cabana type building with little room on 3 sides, so this folds very easily to the side. quality feels good and so far has performed very well. Recommend this to anyone. buy without worry !
