Can I create a ‘jump’ from a current outlet for 2 more outlets?

I’ve removed a shower/bath insert and have open walls, no drywall, with access to the back of 1 outlet that’s facing the hallway. Can I splice into this outlet for 2 new 15A Dedicated GFCI Circuit required outlets for the Jacuzzi tub with a heater I am installing? If not, please advise the safest process. House and electrical box are in good condition for being 30 years old.

Pretty sure that tub is going to require its own circuit.
and I'm right
The whirlpool tub motor must be wired to its own dedicated circuit in the service panel. If your whirlpool tub has a heater, that must have its own dedicated circuit, as well. Tubs requiring 240 volts must be directly connected to the power supply. Tubs with 120 volts are plugged into GFCI receptacles.
Thank you for your response. You hit it on the head according to an electrician I reached on yelp. He is going to install 2 circuits and two outlet for $650. I think that's a reasonable price for a licensed electrician.
