I have a North Trail 30rkdd. It has the corner stand up shower, and the faucet is on the outside wall, drivers side. I need to replace the faucet, due to to the faucet diverter tee cracking. There is no access/access panel to behind the faucet that I can find. Does anyone know of a way to get behind the faucet or as anyone else dealt with this? And if so, what can be done? Much thanks for any help.
