Install a Riser for the Throne (Toilet)

toilet.JPGAs we get Older it is harder especially for us older folk to Get off and on The Throne. I’ve found over the years that most RV’s have small toilets and many are way to low for a tall person. I always hated the small round ones and replaced all of the toilets in my Sticks and Bricks Home with tall 19 inch Elongated ones. The one in my Motor home was elongated,but not High enough in such a small space, and was hard to get off of without my old joints complaining. I finally decided to do something about it.

Originally I was going to build a box to raise it up and set the toilet on the box, That is until I discovered a universal one, made by Thetford Brand New for around $30 with Gaskets and Hardware. I found a used one on Amazon for $22 including shipping. When I got it I took it out of the box and it was brand new. Not a mark or blemish on it and the gaskets and Hardware were still in the original plastic envelope. I think what happens is some one bought it and it did not fit or was the wrong item and returned it. Once the package has been opened it cannot be sold as new again. I have bought many so called used items off of Amazon that when I got them they looked brand new.

First off I had drained and flushed the tanks before Winterizing the Motor home, so there was a couple of gallons of water mixed with RV antifreeze in the bottom of the tank along with my own deodorizer and cleaner formula. I unhooked the supply line from the toilet and undid the two nuts holding the toilet to the floor flange and lifted the toilet straight up and set it on a garbage bag that I spread out before hand. Yhe old gasket was still stuck to the Flange, so I grabbed it with rubber gloves and it came right off. I got a big gob of paper towels and after wiping the floor were anti freeze had spilled out of the toilet, I cleaned the flange. I took the wad of paper towels and stuffed them in the pipe although there was no smell. I then turned the new Thetford riser over and installed a new gasket. There are 2 sets of long bolts that came with the hardware. I choose the shorter set that stick up through the Riser from the flange and the toilet slips over them and the nuts are tightened to hold the toilet and the riser to the floor. I thought I would need the longer bolts, but had been forwarned that the longer bolts may be to long. So I opted for the shorter ones. I then placed the riser over the bolts coming up from the flange to check the fit and clearance. The Bolts wobbled all over the place and kept coming out of the flange. I should have gotten some plumbers putty or modeling clad to put around the flange and base of the bolts to hold them in place. It would have made the job easier to put the riser over the bolts. I finally got the bolts lined up and the riser set over the flange. (See) Picture below.

Riser setting on Flange in floor. New Pex Pipe and Shut off valve. The Original water pipe for the toilet did not have a shut off valve and you would have to turn off all of the water supply if you needed to work on the toilet or replace the valve inside. So I added a valve and redid the water line using Pex pipe and fittings. the valve is pex also and a lot easier to install. Pex is a lot stronger but hard to work with. Since I already had the Cinch or pinch rings, and the tools I decided to go with Pex. After checking clearances and make changes to the water line It was now time to install the toilet and hook everything up.

I turned the toilet Upside down and cleaned the area where the new gasket would go using rubber gloves I proceeded. to clean and installed the new gasket. The Riser was ready for the toilet and held the bolts steady so it was easier to set the toilet on the bolts sticking up through the riser. Warning! don’t forget to remove the rags or paper towels in the pipe before installing the toilet on the riser. I forgot to do so and had the toilet almost bolted all of the way when I pushed the pedal to check clearance and saw the wad of paper towels in the pipe. I had to remove the toilet to get them out. Once the toilet was bolted down and I set on it and moved around to seat the gaskets. I then re-tightened the nuts on the bolts. I then cut the pex line and installed the angle fitting that hooks to the toilet. had to all but stand on my head to get the Pinch ring cinched on the angle fitting. at last it is almost done. see picture below.

The toilet now sits 19 1/2 inches from the floor. It is a whole lot easier to get on and off. The water line and valve are much better than the old setup, and the new shut off valve for the toilet is easy to get to, in case the water to the toilet needs to be shut off. see picture of pipe and valve setup below.

The only thing left is to check for leaks which won’t be until spring or if we get to warmer country sooner. I also will be putting a bead of caulk around the base after the toilet has had a chance to compress the gaskets more. I hope you have enjoyed my little adventure. My parts and materials were under $50 for the job and well worth the time and trouble.
