How to get there from London

When I lived in England, I took the train everywhere. If you're going to be in the UK for more than just a week or two or you plan to take the trains a lot, I suggest a railcard. People under 25 (or something close to that) as well as students can get a Young Person's Railcard, which entitles you to about 1/3 off every ticket you buy. The card, however, is 20 pounds upfront. There are other cards, for senior citizens and other special groups, that offer the same sort of deals. Also, if you buy your tickets more than two weeks or so in advance, you can get them as cheap at 1/2 off without any sort of card. Train tickets from London to Bath would vary based on what time of day and what day of the week you were planning to travel on, but you could expect to pay around 20-30 pounds without any sort of discount. The bus would be much cheaper, probably around 5-10 pounds, but it's slower and less frequent. I would check out the websites for the bus and train services (http://www.nationalrail.co.uk, http://www.nationalexpress.com) to make your decision.
