Uncomfortable toilet seat

Our old camper has a wet bath that we had to replace the shower pan/Blackwater holding tank combo because of cracks. Stool had broken lid so we did a new stool at the same time. We have knee and back issues and with the close quarters standing after doing the paperwork was very difficult so we purchased a high profile stool as a replacement. Much better. We also removed the door and installed curtain track and a heavy upholstery fabric curtain door making entry and exit much better. It also allows us to use the fantasic fan to ventilate the camper without having a solid door that had to be kept open to use. Works for us just fine. One thing tho. We have two under counter doors and the taller stool blocked one so I had to modify it a bit. Just saw it shorter, add a hinge and make the bottom couple of inches solid. Store towels back there.
