This sauna requires a 110 Volt 20 amp outlet. Can I simply replace the 15 amp outlet to a 20 amp outlet and replace the 15 amp breaker by a 20 amp breaker OR do I need to re-wire an outlet (20 amp) using 12 gauage wire? My exisiting wire is 14 gauage. Thanks in advance for answering my questions.

Hello Raymond, 15 and 20 amp outlets are typically the same size and can be picked up at any hardware type store. Regarding wire gauge, I can only advise you to consult your local building codes or a licensed electrician. Different areas have different requirements depending on voltage, amperage, wire run length and possibly other factors.
