Room on the Panel, or an Upgrade?
A 240-volt hot tub is one of the bigger loads in a house. If you're on 100-amp service or the panel's already full, a load calculation tells us which way it goes: fit it as-is, rebalance a few circuits, or upgrade the panel. If the cheaper option works, we say so.
In an older home, it's worth a safety look before you add a load this size. An electrical safety inspection is a good place to start.
