Good morning, due to buoyancy you will float a little bit but you shouldn't float up to the surface. I would like to mention that if the lounge is sectioned off like a cockpit your less likely to float as much. Open lounges allow the water to flow up underneath you as jets are running and you tend to float more. Hope this helps!
Good afternoon, Make sure to choose roto-molds from manufacturers like Sundance or Jacuzzi who prioritize easy access from the sides. Avoid roto-molds that lack convenient access. This information should help guide your decision. However, you still won't get all the benefits you would get from a self-supporting hot tub. hope this helps!
