Best 10 Inch Rough-in Toilets Reviewed and Compared

Looking for a 10 inch rough-in toilet for a small toilet space or to replace your old one?

I know a 10-inch rough-in toilet can be tough to shop for. It’s easy to find a good 12-inch rough-in toilet, but when it comes to 10-inch toilets, you’ll need to dig a little deeper.

Shopping online or in a local plumping supplies store, it can be hard to tell what’s high quality or low quality. Beyond that, it’s hard to know whether you will like it or not after installing and using it for sometime.

In this post, I want to show the very best 10 inch rough in toilets I’ve found, sprinkles with valuable tips and info for choosing the right 10″ toilet for your needs and preferences.

But if you are in a rush, here are my top choices in a comparison chart:

* If space is constrained, choose a model with a shorter length. Not all 10″ models are meant for saving space. Some have the same dimension as the 12″ models.

* Seat Height: Standard Height (14/15 inches from floor) are easy for kids and shorter adults. Universal/ Comfort/ Right Height are (17″-19″) and ADA compliant, good for tall adults and older people.

* GPF stands for “Gallons Per Flush”. US Federal standard requires toilets to be 1.6 GPF or less. Old toilets before 1990’s used to have 3.5+ GPF. Today most normal Toilets have 1.6 GPF. Toilets with 1.28 GPF or less are considered, “High Efficiency Toilets.”

My Favorite 10-inch Rough-in Toilet:
Toto Aquia Dual Flush Toilet

This is a awesome toilet. It’s unique from the others you’ll see around here because it has a sexy skirted design with a curved base. The design is a stroke of genius and provides more space for you with its small footprint.

Made from two separate pieces, the Aquia connects together to take up less space and to bring the base closer to the wall. It also comes with an attached seat.
