But hauling the porti-potty has been a bit of a pain. It's convenient, works, etc etc but is a hassle to carry out and empty and as I knew it not to be a permanent installation never really did a special base for it other than a quick job out of wood to keep it from sliding during transport. After learning about recirculating toilets with their integral holding tanks, and not wanting to pull the pan to install a black tank, the search was on.
This one is from an Ebay auction, working and in reasonable condition. Cindy Ross was kind enough to give me photocopies of the original manual they had laying around- a huge help there in knowing how much water to add!
The hole was already empty, so just a bit of cleanup and new bowl wax, I thought I was ready to go. However, installation wasn't quite plug and play, as the rear of the toilet is much larger/deeper to the rear than either the original or the sea-land. Home Depot had a neat little deal on the shelf, an offset toilet closet flange. It moved the hole forward about 2", just enough for me to squeeze the Jensen in.
Had to build a base for it, out of .063" aluminum with a plywood top. Took a few hours of cutting and folding but it's pretty darn sturdy. As it should be for the best seat in the house! The aluminum is riveted to the floor and sealed around the perimeter. You can see the two levels of plywood, I used rivet nuts in the aluminum to secure the plywood to the top with five 1/4-20 bolts.
Next I set on the adapter for the toilet. It's held to the plywood with four screws and the standard two closet flange bolts. Extra gasket wax here, don't want anything to leak!
And here she is, mounted in place. When it's all right, it's so easy...
