We carried out an extensive amount of research with the Lazy Spa rage. We came across a couple of these 'thin' walled models. Lucikly, they had one on display in one of our local shops so we had been able to assess how strong and durbale we think it would be. We were also able to get a gauge on the size.

We are really impressed with our Singapore spa. It was 100% the right choice for us. It sits perfectly on the patio, on it's lazy-spa mat. Yes, you can hear it because the pump is on all the time but it's not too noisy, and now I hear it and I associate the sound with the joy of being in the tub itself!
The jets are fantastic, just right. We quite like sitting in it without any bubbles and have them on occasionally for a short blast. We have not installed the app on our phones yet, perhaps that will be this weeks job.

Cannot recommend this enough. We love our lazy spa :-)
