Water on the floor from behind shower enclosure

[Tjsatterly]

2022 Coachmen Nova 20c Li3
Water is leaking from shower sink faucet fixture behind enclosure onto the floor. How do I get to it? Cut a hole in the fiberglass? The fridge/freezer is next to the shower separated by wood wall. Do I pull out the fridge/freezer and cut a hole in the wood wall?
How do I get a new replacement faucet/shower fixture?
Thanks in advance for any advice.

All fixed

Well, I got it fixed with some pro advice.
The leak came from shower head flex hose connector.
Tightened the connector and no more leak.
Access was already available though wall between fridge and shower. Had to pull out fridge.
Lesson learned.
