How to Choose The Best 10 Inch Rough In Toilets

When picking a new toilet for your bathroom, there are a few important aspects to consider. Examine the following sections of this buying guide to learn more.

Best 10 Inch Rough In Toilets 2 Img

Water Savings VS. Flushing Power

High-efficiency toilets allow you to flush using very little water, especially when compared to older toilet models. In fact, the average 1.26-gallon flush toilets can save you upwards of about 16,500 gallons of water per year. However, one must keep in mind that lower water usage toilets may lead to a sacrifice in flushing power. As a result, you may not be able to dispose of all the waste in one flush.

Many people find that the 1.6-gallon flush is just right, balancing flushing power against water savings. This fact is actually one of the reasons for our verdict.

Examining the Height of Your Toilet

Manufacturers tend to use terms like “Comfort Height” “Chair Height,” and “Standard Height” to describe their toilets. It refers to how far the rim sits up from the floor. Chair height toilets will typically meet ADA guidelines, making them the most suitable for those with disabilities and mobility issues.

Standard height sits around 16 inches off the floor. Comfort height is often used to describe a rim that sits closer to the floor than a standard. Also, keep in mind that the distance between the seat and floor will be greater once you add the seat itself. Manufacturer measurements typically refer to the distance between the rim and the floor.


Q: Did You Measure Correctly?


A: A 10-inch rough-in refers to the distance between the drain pipe and the bolts on the base of the toilet, which should measure to be exactly 10 inches. Failure to ensure that you have the correct measurements could make it impossible for you to install the toilet. So, even if you’ve measured, consider taking one last check.

Q: What tools will I need to install my toilet?

A: To install your new toilet, you’ll need an adjustable wrench, utility knife, cutting pliers, a rag, and possibly a screwdriver. You’ll also need rubber gloves, a new wax ring, a paint bucket, and lubricant. It can also help to have extra bolts handy, just in case the old ones are too rusted to install the new toilet.

Q: Can I purchase a different tank for my toilet? The original is too small.

A: Sometimes. Certain toilets are compatible with other tank models, yet with others, you only have the option of one size.

Q: How long should the parts inside my toilet last?

A: The quality of materials, number of people using it and the overall quality of your parts will determine the life expectancy of the various components to your new toilet. However, the “average” time is around four to five years for most parts.

Final Verdict

While the right toilet for your needs will likely depend on a variety of factors, our number one choice for 2020 is the Toto Drake Two-Piece. The reasons for this include these particular models affordability, customizability, and powerful yet conservative flush.
