Simply Build It

2 tonnes is a massive weight to apply to a floor. Is the floor timber joists or concrete. If timber it will most certainly need additional reinforcement.

I'd get a Structural Engineer to look at that.

Following your recent request, find out the size of the timbers first then looking in building regulations for loading on timber members. Is the hot tub going right next to the wall or is it going in the centre of the room? Centre of the room will have more sag for the timber members. 2 Tonne is quite a lot, I wouldn't suggest it as an architectural technician. Try finding another location, & don't waste your money on a structural engineer, overpaid and underworked.

Inver,
2000kg is well in excess of the imposed load that a domestic floor can carry.

You will have to work out the dead loading currently, and then work out the suggested live loading, (what is the wt when the tub is full by the way??).

From that you can work out the bending moment, shear, deflection and hence the design size of the floor members required to strengthen it.
As such you will have to carry out design calculations, as the loading will probably be a point loading and not uniformly distributed.

It is almost certain that the current floor joist are inadequate and not able to support suggested the load.
It will probably require steel beams (UB) to support the loading.
You would be well advised to consult the local Building Control officer before carrying out any work
