A common concern from heavier floaters is if they'll even be able to float in the sensory deprivation tank. Quick answer: yes, you will float! Even as a heavier individual, you will still absolutely float in a tank. In fact, people with more mass generally have an easier time floating than more lean individuals. This can be generally attributed to the fact that body fat has a lower density than lean muscle. Therefore, individuals with higher percentages of body fat will find that they have an easier time floating than those with lower body fat.
We've talked to multiple individuals who enjoyed a long float to ease their muscles and joints after a workout. Quite a few of our heavier readers have confirmed that floating does indeed provide relief to ankles, hips, and knees after a gym session.
Finally, you should have no concerns about a float tank being too small. The general size of a float tank is 8 feet long, by 4 feet wide. Even the largest individuals will have no concerns fitting comfortably inside of a tank. Also, the door on a float tank is equally as large, so entering and exiting should be of no concern. Do exercise caution when talking on the steps, however. They will be wet and can be quite slippery. Most float centers put non-slip padding at the entrance of their tanks to ensure a little extra safety for customers.
