Yep, that's the place.

Can recommend it - but they will try and sell you lots of their stuff (naturally). I used to go on a Sunday morning, as it was quite easy to park then; Saturdays Chiswick is very busy. You jump in what is a very hot bath which has dead sea salt already added, then a canopy with the ultraviolet light is lowered(safety glasses provided), and you switch the jets in the bath on and get nicely pummelled. You do a 'kebab' type thing, and turn around in the bath so all of your "bits" get the lights on.
Dressing gown, towels all provided, you are in a completely private room with no interuptions.
Hmmm, think I might make another appointment and go again soon
