Yep, it's possible and easy to do
Simply remove the pump and the bowl from the base....rotate the base 180 degrees, then turn the intake elbow at the rear of the bowl to point in the opposite direction. Re-mount the pump and the bowl, and you should be good to go after you connect the hoses.
It's best to do it off the boat on a workbench (except for mounting the bowl onto the base).
As for the new Elegance...it has an all-ceramic bowl and a much smaller mounting footprint than the Atlantes has. In standard form, it will be fresh pressure water only and exceptionally quiet! For raw water applications, a remote sea water intake pump will be available. You only have to add the pump, no modifications needed to "convert" it.
When Vic at Raritan first told me about it in August, here's what he said: "What’s really interesting about it, other than the low sound level, is how it lushes. It has a special programmable wall switch. Like the Tecma, it doesn’t flush continually when you press the button. Instead, it flushes for a couple (maybe 2 or 3) seconds, then stops for a couple (2 or 3) seconds to clear any entrained air, then flushes again, for a total of three start-stop cycles. It’s really neat, and the suction is outstanding! We are calling it “Vortex-Vac” technology...The “vacuum" is created right in the actual bowl."
Front to rear dimension at top of bowl is 18.65” Max. width (bowl and seat) is 14.36”. Total footprint is 8.5” wide x 13.5” deep. To raise seat and lid requires a clear height of 32.25” from the deck level of the head.
List prices: pressure water model (built in solenoid valve and vacuum breaker) - $899.00. Raw water version, requires additional pump that is remotely-mounted (pump is included; inlet strainer isn’t) - $979.00.
