Bali - the Thai Consulate is no longer open in Denpasar. Now you have to travel to Jakarta if you wanna get a SETV. Just in case anyone thinking about it.
Depends where in Thailand too. I'm in the north. Serviced apartment for 10,000 + electric. I don't cook here, so eat out at local spots but go somewhere nice a couple times a week or order at home, I go out for coffee everyday (that's a non negotiable) and by no means am I scrimping by. You could easy live on £800-£1000 a month and live comfortably. Including my insurance etc. I don't really drink, so probably I'm saving there and no bothered about the gym, I just do yoga/walk.
