Things to Consider When Buying the Best 10 Inch Rough In Toilet

There are several reasons you might need to consider when buying the best 10 inch rough in toilet. We have listed all the key features you must consider before spending money on buying the toilet. 

Toilet type

Once you have decided to buy a 10-inch rough-in toilet, the next step is to decide on picking the right toilet type. The one-piece and the two-piece are the most popular toilet types available on the market. As the name refers, in one-piece design the toilet tank and the bowl are directly connected. The one-piece toilets are easy to clean as they lack the joints. On the other hand, the two-piece toilets are cheaper and easier to install. 

Bowl design

The third thing to consider is to decide if you want a round or elongated bowl design. A round bowl design is best suited for small bathrooms while elongated bowl designs are great for people who want a comfortable unit.

Flushing Mechanism

The toilet flushing mechanism is the main selling point of any toilet. Different toilet models use different flushing mechanisms, some toilets use siphon jets, whereas other toilets use gravity flushing mechanisms. Compare different flushing mechanisms and choose a toilet with a strong flushing system. A toilet with a powerful flush system will save you water because it will not require multiple flushings to get rid of waste. 

Water Usage

The water consumption is another important factor to consider when buying a right toilet. Consider a toilet consuming water no more than 1.6 GPF (Gallons Per Flush). There are some toilets that consume only 1.28 or 1 gallon per flush. The low water consumption helps you reduce your annual water billing and in some states you may get eligible for rebate. 

Toilet Installation

The toilet installation is another important factor to consider when picking a 10 Inch Rough-In Toilet. Some toilets Installation needs the help of a professional plumber, while others can be installed with great ease. Generally, one-piece toilets are heavier therefore they are difficult to install than two-piece toilets.

Bowl Shape

The toilet bowl has two most common styles; round and elongated. The elongated toilets are designed especially to enhance the  user’s comfort. Whereas the round shaped toilets are suitable for small sized bathrooms or for saving the space. 

Ease of cleaning

The toilet design and the comfort level are primary things. But this never means, you completely ignore the ease of toilet cleaning. Some toilets have additional coating that prevents waste or other particles from sticking to the toilet bowl. Such toilets are easy to clean and maintain. We personally suggest you consider buying toilets that are easy to clean so you have good hygiene.

Bowl height

To enhance the user comfort level, reputed toilet brands are manufacturing ADA (American with Disability Act) toilets. These toilets are also referred as Chair height toilets, they are generally taller than the standard toilets. Usually, the comfort height ranges between 17” to 19” inches from the bowl base. 


Buying a toilet is not an easy decision, you need to consider so many aspects. If you have a compact sized bathroom and are looking to install toilet, we recommend you pick TOTO 10 inch rough in toilet Toto Drake II .
