Thermal hot tub cover
Rating: 5 out of 5
I bought the thermal hot tub cover a few weeks ago and I’m very glad I did. It has made a tremendous difference to holding the heat in, It’s well made and It adds another layer of protection to the tub when not in use. Last but not least it looks nice.

Great first time tub for two
Rating: 5 out of 5
First time buyer for a hot tub and decided on a miami airjet as there is only me. I found it to be easy to assemble even though the instructions weren't the best (printed on one of the flaps on the box) once up it was larger than I expected. I also bought a thermal cover and a cosy spa mat to help keep costs down. The tub has a 7 metre electric cable with a rcd on it, however if your electric trips you will need to reset this as it doesn't restart like all your other electrical items in the house. The filter runs 24/7 and I have heated up to 34 which I find comfortable. The control panel is easy to use and once up to temperature the light is green, where as the filter is constantly red to show it's running. Once filled with water and the treatments are done and everything is balanced it was time to get in. Although you are sitting on the floor it's not uncomfortable, I am nearly 6ft and can have my feet one side and me head on the other resting on the side. The filter runs quietly in the background and the bubbles run quite loud, easy to forget and speak loud so everyone in the neighborhood can hear you lol. As this tub isn't an energy sense one I got a thermal cover and so far this has kept the temperature at my desired temperature but it is summer and we have been lucky with the warmth. I invited two friends to join me and we had enough room, I think four adults will be less comfortable. All in all a great tub for a first timer or for one person

Worth every penny
Rating: 5 out of 5
Worth every penny. We have the Toronto foam spa, which to be fair, is more energy efficient, but the lid is the same as the inflatables, so can still lose a lot of heat. The thermal cover is fantastic for 2 reasons. 1. We had the power off for a week and the temperature when turning back on was 26 degrees - only 10 degrees lost in a week. 2. Any rain collects on the thermal cover, keeping the actual lid dry. I cant tell you how many times I've tipped rain water into the spa trying to get the lid off! No more!! Its nice and thick and hard wearing. The pictures make it look like there is a space in the cover for the separate power units, but if you have a built in one like mine, the cover has a zip in bit so you dont have a gap.

HOT TUB Insulation Cover
Rating: 5 out of 5
Very well made OEM product.
Much better than aftermarket products from other outlets.
Make the retention of heat much better than a tub without the cover.

Should be included as standard
Rating: 5 out of 5
This is a game changer, with current energy price increases. I wish I knew what a difference it would make when I had my previous spa.
In my opinion these should be included as part of the spa purchase. Realising the need to spend another £100 after spending over £1100 for the spa is a bit upsetting.

Big reduction in operating costs
Rating: 5 out of 5
We bought the insulated hot tub cover with the tub itself. It is very efficient, with outside temp about 8 Deg C, and the hot tub heater off, the water temp only dropped about 5 degrees overnight. The cover makes sense environmentally and financially.

Great item better than expected
Rating: 5 out of 5
I was very impressed with the thermal quality of this item.
I turned off the heater overnight and lost only 2 degrees of temperature.
The item fits perfectly and was compatible with my hottub.
The cover is durable and I expect it to last years. Well worth the cost.

Thick cover
Rating: 5 out of 5
This is the first time I have bought an additional cover for a spa and I am glad I did. It is super thick and covers my spa perfectly with a zip opening small part to accommodate any filter units or in my case the spa settings unit. It looks like it will last a long time and though expensive it should earn its money back with a reduced heating bill. I recommend this cover

Seems very robust
Rating: 5 out of 5
Bought this to replace a different thermal cover that had sen better days and must say, I am impressed with the durability of the cover. It has what appears to be a very robust plastic outer but time will determine how it wears. Very pleased so far and much easier to remove and put back on from the other cover I had.

Very effective insulation. You can feel the warmth when the cover is lifted. Very well made and string material which fits perfectly over the hot tub

AMAZING, Thick, sumptuous and well crafted cover.
Rating: 5 out of 5
AMAZING, and well worth every penny. The cover is thick and really well built. It is a bit heavy but that is because it is full of insulation and layers of padding. I have it on my HotTube over winter and during the day and when I have not had the heating on I only loose about 2-3 Degrees. It cuts the heating time down as it keeps in all the lovely hot water. If you are going to get a thermal cover, definitely get this one. You wont regret it.

Had this on for 3 weeks now, only using the spa a couple of times a week, I’ve noticed the daily running cost has reduced by about £1.25 set at 37 degrees, perfect fit and would definitely recommend.
