NT, you probably already prepared for it but please make sure you spread the point load from a full bath over several joists not just on packers on the floorboards. If you're leaving the bath open, you might need to double up the joists underneath the feet.
Yes, the position is just to work out how it fits, if there will be enough head room, and how much packing is needed to get it level. The bath will be boxed in so nothing will show.
I will likely have 1+" thick oak boards to spread the weight over the three joists under the bath. I may also put some steel plates between the feet and the oak as the feet seem to land 'on point'.
The only thing I am doubtful of is if the three 6"x2" joists are really up to the task. The wall on the right is a supporting wall while the wall on the left is a partition and the joists extend another 10' to the next supporting wall.
A future job is to remove the ceiling underneath as the plaster boards are loose anyway. At that time I can add additional joists if needed.
However, if you have concerns I will heed them and redesign the room layout.
