What is an RV Porcelain Toilet?


Porcelain toilets look the same as you have in your residential toilet, bringing a sense of home to your RV. Many of them come with a sprayer. These are toilets made out of porcelain, so they look shiny and smooth.

Also, it is easy to keep the porcelain toilet pristine. You can scrub it with a toilet brush or white vinegar if there are any tough stains. Also, dirt washes off quickly, so they can stay looking luxurious for a long time without any problem of discoloration.

One of the drawbacks of a porcelain toilet is its weight. It weighs around 30-50 lbs, which can weigh down your small camper. Also, the price can be a bit too high because of its high-quality design.
