RV Toilet Bidet Seat Adapter by LMBK88LMBK

This is a printed insert to adapt the Bio Bidet SlimEdge Simple Bidet to fit onto the Dometic 300 Series RV/Trailer Toilets. You will need to print one regular, and one mirrored. The cheaper RV toilets do not use standard residential toilet seats. I adapted the Bio Bidet SlimEdge to fit onto the RV toilet so that we can have a bidet on the road. Anyone who has used RV toilet paper for an extended amount of time knows that a bidet should really come as standard. It not only cuts down on TP usage, but also prevents clogging due to TP.

You will cut the bidet attachment where the 3D insert meets it. See pictures for reference, to ensure that it clears the back of the toilet. I used an oscillating saw but a dremel or some other small saw would work. I predrilled the holes in both the bidet and the insert. I attached the bidet to the toilet first using the inserts as a guide to locate the bidet. Then added the inserts. All of the plumbing should be hooked up first to ensure no leaks.

And this 1/2" to 3/8" adapter:https://www.amazon.com/LASCO-10-0061-Compression-Adapter-2-Piece/dp/B0083GC574/ref=sr_1_4?dchild=1&keywords=G1%2F2+to+3%2F8&qid=1616892984&s=hi&sr=1-4
In addition, the toilet seat hinge point will need to be raised or the seat will interfere with the bidet itself. I used some steel pipe strapping and some plastic spacers. I cut the strapping approx 1" long so that two full holes were available. The bigger hole I used for the seat side hinge, the smaller hole I used for the toilet hinge side. I purchased some 6-32 x 3/4" screws with nuts to go through the old hinge hole on the toilet side, and through the two strap holes on each hinge. On the toilet seat side, the existing set screw went through the lid, strap, spacer, strap, seat on each side. The result is the seat hinge point is now high enough to not interfere with the bidet.
Feel free to ask any questions in the comments. I'll do my best to add pictures or comments to address what I did or solutions for different scenarios. Not ever RV manufacturer may use the same plumbing sizes that were used in my Trailer. My toilet is a Dometic 300 series. This should work for any Dometic 300 series toilet.
