How to Choose 10 Inch Rough in Toilets?

How Much Water Do You Want to Save?

You may not know this but you can save a significant amount of water just with a quick replacement of your old toilet. Older models can waste thousands of gallons in just a few short months. One that has a gallon per flush rating of 1.28 will use up to 17,000 less gallons over the course of a year.

The problem with this ultra low consumption rating though is that it may not be strong enough to remove the waste that you see in the bowl. It’s often better to pick one with a rating of 1.6 gallons. This helps you save water and keep the bowl clean at the same time.

How High Do You Want to Sit Off the Floor?

Manufacturers typically use terms like comfort height, standard height or chair height to describe the distance between the seat and the floor. You need to make sure that this refers to the height from the seat and not the rim. When you add a seat, you may wind up several inches higher in the air.

Chair height is a distance similar to the distance between the seat of a dining room chair and the floor. Standard height is usually around 16 inches. A manufacturer might use comfort height to describe a shorter distance from the seat to the floor.

Did You Measure Correctly?

A 10-inch rough-in means that the distance between the bolts on the base and the drain pipe in the wall is exactly 10 inches. Manufacturers make models with a rough-in of between 10 and 12 inches, though other models mount right on the wall or closer to the wall. Choosing the wrong rough-in will make it impossible for you to install the product in your bathroom.
