What do people say about Lay-Z-Spa foam wall hot tubs?
Absolutely love this, we upgraded from an inflatable one we had for a number of years. Using at least half the electricity. It was easy to set up, it really holds the heat and is cheap to run.
Previously we had an inflatable and this version really is cheaper to run.
I had an inflatable tub previously, but this is a game changer. No risk of punctures or having to reinflate it. You get more space inside with a standard size footprint.
The insulation works a treat keeping the temperature within a degree over night, the pump power usage is low and we keep the heating on all the time to keep the temp.
I have had the inflatable ones in the past. This foam one is far superior as it holds the heat in much longer. The heat up time is much quicker. Its larger than the former spas I have had and the bubbles are better. It is also easy to put up and take down. The pump is easy to use and operate.
It has noticeably reduced my electricity running costs. It only drops 1 degree overnight without any heater being on.
