Welcome to our forum.
I forgot to say that I am based in the UK so I think the problems we run into might be a little different to those in the US.Thanks Bull Frog! They look pretty good. Maybe a little expensive, with the tubs costing about the same but it's what I'm looking for. They don't mention delivery overseas but could probably be arranged.Dr Spa - that's a good point, however I think things are a little different in the UK. We can pick up comprehensive public liability (accident/injury for the user including death!) for around £190 for the year. Which is pretty good! This might be due to our free health care.Tman - I've heard that these lose quite a lot of heat through the base, so it's good to have a thick floor mat to keep the water temperature at a comfortable level. Trust me we need it over here! Especially in the north. And we have power sockets everywhere in homes in the UK so can easily use an extension lead to get power anywhere.
