Sometimes It’s Better To Buy A New Toilet
Keep in mind that plastic RV toilets are not all that expensive to buy new.
And since you usually have to remove the toilet first in order to do any necessary repairs, it often makes more sense to just replace it
Especially if you go to an RV dealer to have the work done, then it will probably be cheaper in the end to replace your RV toilet instead of repairing it — once labor and parts are figured in.
Installing a toilet is a do-it-yourself RV project that can save you $150 in labor — as long as you don’t mind getting your hands a little dirty!
RV Plastic Toilets vs Porcelain Toilets
What if you’re just tired of the toilet in your motorhome being plastic and chincy? Can the toilet be upgraded?
Yes, your RV toilet can easily be replaced with a porcelain toilet like those used in residential homes. In addition to the added weight of a porcelain toilet, the biggest downside is the amount of water that it uses with each flush. A traditional RV toilet is much more economical on water usage.

I’ve been involved in RVing for over 50 years — including camping, building, repairing, and even selling RVs and motorhomes. I’ve owned, used, and repaired almost every class and style of RV ever made. I do all of my own repair work. My other interests include cooking, living with an aging dog, and dealing with diabetic issues. If you can combine a grease monkey with a computer geek, throw in a touch of information nut and organization freak, combined with a little bit of storyteller… you’ve got a good idea of who I am. To date, I’ve shared my RV knowledge in over 300 articles here at The Fun Times Guide! Many of them have over 25K shares.
