What is RV Toilet with Shortest Rough In Dimension

Updated 05/26/2026 | Published 05/24/2026

Question:

Will the low profile Aqua Magic II replace a standard height Aqua Magic VI our measurement from the wall to center to the closest mounting bolt is about 7 3/4 The trailer is a 2018 Airstream 23FB with the bathroom in the rear. Our platforminch is about 9inch tall. Ive attached a couple of photos of the toilet/bathroom area. And, yes, the bolt on the left really is about an inch closer to the back wall about 7 3/4 than the one on the right about 8 3/4 due to the curvature of the Airstream wall. If this wont work, do you have any recommendations?

Hey Charlie, it doesn't look like we have a good option unfortunately. The toilet we have that has the smallest rough-in dimensions is the part # DOM74FR which has a rough in dimension of 8-3/4 inches. With that said I am not sure how you got an Aquamagic VI to fit as that should have required quite a bit more of a rough in dimension.
