Your only bath, thats why they make 5 gallon buckets and Burger King has
clean washrooms. Tub stays but if supports are rotted no. My last 2 day
bath redo was new sub floor, new joists supports even the ceiling below
had to go. For years water went to the lowspot, the toilet and rotted
alot of wood. It ended up being a week using a 5. Removing the vinyl
will show alot as will floor flex indicate rot. Tile needs to not move
at all. A pro will point out possible issues. Baths easily take the
longest of any job due to unforseens from years of water unseen to you
but finding wood to rot.
