Walk in shower or wet room

Good morning everyone 🌞 I would like to advice .I have arthritis  also cerebral palsy I also live in the council flat which has a bath which I love but because of my health deteriorating I got in contact with adults and elderly service or Greenwich they took a lot of information from me what would really suit me would be a walking shower not a wet room so what I'm asking is if the Greenwich council says they only offer to a wet room can I refuse?? I am not wheelchair bounded I can get around my flat I can get into my bath but I find it difficult now to get out of my bath I don't have the strength to get myself out of the very grateful any advice
