“How do you make sure the water’s clean?”

Sanitation and hygiene are very important to us at Float in the Forest.

Everyone must shower

Everyone is required to have a shower and wash themselves thoroughly before they get into the float pod. This includes their hair. 

The purpose of this is to get rid of dirt and oils on their bodies.

Preferably no swimwear

We encourage people to float naked, partly because this reduces the risk of bacteria associated with typical swimwear.

There’s no need to feel self-conscious – your room is private.

Salt is inhospitable to bacteria

The water in the float pod is super-saturated with Epsom salt (Magnesium Sulphate). This is primarily for the buoyancy it provides, but it is also useful for hygiene reasons.  Such a high density of salt also happens to be a very inhospitable environment for micro-organisms.  It is as dense with salt as the Dead Sea, so think how little survives in that.  There is over 500kg of Epsom salt dissolved in the water in one float pod!

Very fine filtration

But that’s not enough for us.

The water is filtered thoroughly.  In between each person floating, the entire quantity of water passes through a one micron filter several times.

For a size comparison, one micron is at least 50 times smaller than the average human hair!


The final stage is chemical sanitation. You might expect us to use chlorine, from your experience in swimming pools or hot tubs. However we don’t tend to use it in float pods as chlorine can produce an unpleasant chemical smell and stinging eyes from vapours in the air. We don’t enjoy that, and we don’t expect you to put up with those sorts of distractions during your relaxing experience.

Instead our pods automatically treat the water in between each person floating, with a combination of high intensity ultra-violet light and a measured quantity of safe odourless sanitiser. This combination has twice as much oxidising power as chlorine. Once the chemicals have done their work, they break down safely to just oxygen and water.

Regular testing

The float pod water is tested regularly too, as part of our rigorous procedures.

You can rest assured that we uphold the highest standards of hygiene, in fact our pods are a far cleaner environment than many swimming pools.
