Description Description

Experience superior heat retention with our thermal cover lid engineered specifically for Lay-Z Spa inflatable hot tubs. This industrial-grade insulating hot tub cover utilizes an extra thick 13mm layer of closed-cell foam insulation for unbeatable thermal performance.

Our proprietary thermal insulation formula is lab tested to drastically reduce heat loss by trapping and containing heat. This enables substantial energy savings and significantly cuts reheating time after use.

The lightweight yet extremely durable construction features a raised center support to prevent water pooling even under heavy rainfall. The weatherproof design keeps your hot tub protected from the elements.

With Lay-Z Spa hot tubs, up to 50% of precious heat can escape through the open top. Our thermal cover lid acts like a blanket to lock in heat for maximum energy efficiency. Save on electricity bills and enjoy your desired hot tub temperature for longer periods.

Easy to secure before use and remove afterwards or leave on year round. Fits all current Lay-Z Spa inflatable models. Achieve optimal thermal enclosure when paired with our Lay-Z Spa insulating jacket and base, sold separately.

Stop wasting money and energy due to heat loss. Invest in this premium thermal cover lid to keep your Lay-Z Spa hot tub piping hot and ready to enjoy.

Significantly Reduces Heat Loss

Important Product Protection Information

Our thermal products are designed to improve heat retention and help reduce heat loss from your hot tub or spa. Please note that thermal products are not designed to be UV-protective or fully weatherproof outer covers.

For added UV and weather protection, we recommend using our Deluxe Cover range. Deluxe covers are designed to fit over and around our thermal products, helping protect the thermal set from sun exposure, rain, wind, dirt, and general outdoor weathering.

For the best all-round protection, we recommend combining your chosen thermal products with a suitable Deluxe outer cover. This gives you both thermal performance and weather/UV protection in one complete setup.

Need help choosing the right option? Contact our team and we’ll be happy to recommend the best cover combination for your hot tub.

Lid Size Information

Our standard lid sizes are designed to fit correctly when used together with Cwtchy Covers thermal wraps/jackets. This allows the lid to sit over the thermal set as intended.

If you are purchasing a lid without one of our thermal wraps/jackets, please contact us before ordering for size information and bespoke options. Our team is always here and ready to help you choose the best fit for your hot tub.

Nearly perfect

The cover is excellent, it fits my Miami 1.8m pool and with top and side cover in place it is dropping 2deg overnight with the heating off . Air temp 14 Deg. The issue is the crossing attachment for the poles, a small grub screw isn't effective and needs something more substantial.

Best fit

We haven’t switched on our Lay-z-spa Mauritius yet for spring but the lid is on and is a great fit - the original lid never seemed to be big enough so that’s already a plus in this one’s favour. We’ll wait to see what savings we can make in using this lid - also happy not to contend with the inflatable lid as they seem to puncture and allow water in very easily.

Well made and does the job.

We’ve gone from seeing the heater light being mainly on red, since fitting the insulated covers to our lazyspa to now being mainly on green 👍

Fabulous cover, saving us a fortune

We received our cover just over ten days ago, and already we are reaping the savings benefits. Almost halved out hot tub electrical use, and it doesn't cool down anywhere as quick when we are using it. The only criticism is it is rather fiddly to put the lid back on now, but totally worth the savings. 100% recommended.

Easy to use and makes my hot tub cheaper to run!

Can I say how amazing this product is!!! I have been toying with buying one for a year as I already had the lazy spa thermal cover but I was still spending a fair bit on heating my hot tub (I have the square Cabo). It is in a tight spot and putting the cover on was fiddly in the space. Your cover was delivered promptly and so simple to put on. The wrap was quickly installed and the lid is so much easier to put on than the old thermal cover, I have, however, taken the frame off as, on my own in the tight spot, it was tough to lift off without worrying about scratching the surrounding decking that my partner painted. As it has a fold in the middle it is now easily placed on top and tucked in (I have placed a football underneath to stop the rain pooling). It also heats up much quicker and maintains it's temperature for longer. I think this will save me at least £2 a day in electric and so it will pay for itself in no time! As and when any of my family invest in a hot tub, I will be coming to you for their birthday and Christmas presents!!! Thank you again Cwtchy Covers!!!

Cosy tub

I’ve had my Maldives hot tub for over 4 years now, it was a pandemic purchase. We were using it regularly until energy prices really hiked up and I reevaluated the cost of running it alongside a huge house. We’ve recently down sized and set the tub up again in its new location which is less exposed. I’ve purchased thicker matting, I already had an insulation jacket and I’m now using my cover. I know it’s the Summer and we are having a bit of an heat wave even in the North of England so time and colder weather will tell. Overall I’m really pleased with results so far so I would based on my experience recommend the products from Cwtchy.

Good but too heavy

The cover itself seems well made, however the metal supports provided make it impossible to lift by one person . Maybe there could be two costs, one with and one without the metal, as I’ve had to leave it out to allow me to be able to use it. Im not slight or weak, but it was too unwieldy and heavy . My tub is under cover too, so the supports don’t appear to add any value

Good quality and fits well

Good quality and works well with the inflatable underneath. Our hot tub has a covered space, so I’m not sure we want the very heavy iron scaffolding bars that come with it ;-)

Fantastic service and great insulation

This has made a huge difference to my electric bill. Already I've gone from losing 1 degree every 2 hours, to 1 degree every 6 hours. And thats in minus temperatures. Great customer service too, answer emails quickly and really helpful too.
