Like to have the toilet in your RV a little taller? It can be done and without too much effort.

There is a Thetford kit that simplify things. The kit contains longer bolts, new nuts and two seals in addition to the riser which will lift your toilet 2.5 inches. It is not a difficult job …not even in the tiny second bathroom in our 5er… I just got my “narrow” son to do it. He definitely fit in the small space better than I would have.

Follow the instructions that come with the kit, but simplified they are:

• Check the water supply line. The toilet will be 2.5″ higher and you may have to increase the length of the supply to reach the additional 2.5″. Ours did.
• Shut off the water to the RV, drain the toilet and disconnect the supply line. Remove the nuts that secure the toilet to the floor. Lift the toilet up and off the bolts. Clean the base and the flange area and set the toilet aside on newspapers or rags.
• Put the seals in place. Install the long bolts. Position the riser over the bolts. You may need to make a hole in the riser for the waterline.
• Slide toilet down over the bolts and tighten the nuts until the toilet feels secure.
• Check waterline connection once more before turning water back on. With water back on, check for leaks.

If your toilet has a leaking supply valve or flush valve you should make sure you have the parts on had to do those repairs while the toilet already removed.
