I had home births for both of mine. I bought shower curtains (big mistake, very slippery even before it's all started! Shower curtains are big and cheap but perhaps cover in old towels or unwanted sheets), had tonnes of spare sheets that all my family had donated, all to be gathered up and thrown afterwards.
I did hire a pool for my first but we didn't fill it in time so I wouldn't really recommend that.
I had both mine in the living room, my longish hallway was perfect for pacing between contractions, and I stared at my mat notes folder whilst doing window breathing for the actual waves. I had read smth by Ina May Gaskin about natural homebirth, and Juju Sundin, both of which I found really helpful. I am not a hippie type so read them both with a pinch of salt, but found some useful tips to help me through it.
I used a TENS for both, which I highly rate (couldn't turn it up to max as it was more powerful than the contractions!) and I still use for back pain.
Midwife only turned up 15 mins before birth of first (she didn't believe I was in labour) so I didn't get much g&a, and survived on two paracetamol.
I gave birth with both standing up, I really credit gravity with a lot of it all.
Like a pp I also got blue lighted to hospital after my second home birth as the placenta wasn't coming out, but it was still very manageable home experience and I would absolutely do it again.
Good luck all, very doable and so worth it to be in your own home and in control.
