I did it, it was amazing 
You need to chat to your midwife about it when you see them and they can give you more info. Mine was incredibly supportive but it seems like attitudes can vary from area to area, and of course just between midwives! I was very lucky.
I got a birth pool in a box, it was great. Used gas and air which I hated at first then the m/w persuaded me to try again saying, 'just go with it' so I did - gas and air rocks! Said some silly things 
Also, if you haven't thought about it, I would really recommend looking into a hyonobirthing course. It helped me to remain calm and in control during both of my labours (second also at home in pool but much faster!) and I really rate it, we had a great teacher too.
M/w will come out to assess your house at some point later in pregnancy and they have a list of things to go through eg things you need, pain relief, why you may need to transfer to hospital etc. Things you need might be stuff like towels, birth pool, torch, things for baby (changing mat, hat, nappies, cotton wool, clothes etc), snacks for everyone (Inc midwives), coverings for floor or sofa (we used old bedding and tarpaulin) and various other things!
Also, we had hospital bags packed for everyone, just in case. We actually did have to go to hospital with our first after she was born at home, so I'm glad we had packed everything up already as it was a very stressful time and that would have added to the stress otherwise. There are great threads on here about what to pack.
Good luck ttc!
