Space-saving Design

If you have a small bathroom, a 10-inch rough-in toilet will be the most optimal choice for you. The reason is that a 10-inch toilet is compact and sleek for you to save up space in your bathroom.

Despite its small design, a 10-inch rough-in toilet is not inconvenient to use. On the contrary, many compact toilets are equipped with spectacular features, even more excellent than big and bulky toilets.

Types of 10-inch rough-in toilets

There are two main types of 10-inch rough-in toilets. They are one-piece toilet and two-piece toilets.

One-piece toilets are made from only one piece of material. Usually, the material used for making a one-piece toilet is ceramic. Besides, it consists of a trap-way, an integrated bowl, and a tank. The advantage of the one-piece toilet is a straightforward installation.

About the two-piece toilets, they are assembled from the toilet bowl and the toilet tank. Normally, you can adjust the combination up to your preference. The advantage of the two-piece toilets is the durability and their parts can be replaced if they are broken. However, two-piece toilets don’t include a seat, and you have to pay extra money for that.

Powerful Flushing System

Regularly, a 10-inch rough-in toilet will possess the flushing power from 1.6 gallons per flush to 1.8 gallons per flush. The power of the flushing system will depend on the type of flushing system.

There are three common types of flushing systems: dual flush system, gravity flush system, and pressure-assisted flush system. 

The dual flush system is top-notch for water-saving because you can adjust the amount of water used for flushing.

The gravity flushing system will take advantage of the weight of water and gravity to wipe out all the dirt and mold.

The pressure-assisted flushing system will wash away all the dirty particles with one flush only. By forcing the water coming out with pressurized air, every flush of this system is extremely powerful.
