Float tank, isolation tank, sensory deprivation tank, float pod — people search for floating under a handful of names, and they all describe the same thing. This guide covers what it is, what to expect and how to book a float in Cambridge.
What a float tank is
A float tank is a private, enclosed bath of water kept at skin temperature, with enough Epsom salt dissolved in it that you float on your back without any effort, face clear of the water. With the light off and the lid closed, there is almost nothing to see, hear or feel — which is where “sensory deprivation” comes from.
Ours is a modern float pod rather than an old-style tank. It is roomier than most people expect, and you choose how much light, sound and lid you keep.

What an hour feels like
The first few minutes are about getting used to it: finding a comfortable position for your arms, noticing how quiet it is. Most people then settle into a deep, heavy calm somewhere around the fifteen-minute mark. Some drift into sleep — which is fine, as you cannot roll over or sink. Gentle music signals the end of your hour, then you shower in your own room and take a few minutes in the lounge before heading back out.
Why people float
The three reasons we hear most are sleep, stress and aches. Research on floatation-REST (reduced environmental stimulation therapy) has found lower stress scores, lower cortisol and less muscle tension after floating, and many guests say they sleep more deeply that night. The research is still modest in size, so treat these as promising findings rather than promises. Our article on the science of relaxation goes into more detail.
Common worries
Claustrophobia. You are always in control. The lid can stay open, the light can stay on, and you can step out whenever you like. See our guide to floating if you are claustrophobic.
Not being able to swim. It does not matter — the salt holds you up. More in can I float if I can’t swim?
Hygiene. The water is continuously filtered and treated to keep it clean between sessions, and every guest showers before floating. Our cleaning guide explains the routine.
What it costs in Cambridge
A single 60-minute float at Floatwell is £75. If you are new to floating, three floats in three days is £99 — the best value way to start, because the effect tends to build over consecutive sessions. Student and teen floats are £45. Current prices are always on our prices page.
