46 Voyager - Shower Sump

I have a 2005 46 Voyager. I have been unable to locate the shower sump. In the forward state room the floor pullout houses the bow thruster. In the hallway between the two staterooms is the master head macerater. These are the only two floor cut outs I have. In the 45 (two state room) model the sump is in the master state room (not the forward). In the hallway pull up I can see a drain line that disappears heading aft. In the engine compartment I cannot see this drain line emerging to follow it to the sump. From the aft of this hallway floor cut out to the forward firewall in the engine room there seems to be several feet unaccounted for where I assume the pump may be. Just don't know how to get there. Any suggestions would be greatly appreciated.

Thank you for your response. I have seen this on our neighbors 45. The 46 has a three bedroom layout the master being the forward unit. I will be having the carpet replaced soon and will be looking for previously covered access panels. I had posted this question to the carver website but they have not responded. Thanks again for your time.

Just a follow up. Sump was found in second state room, under bed, under carpet. Wish it would be in the lower engine room. More condusive to cleaning. At least it is found.
