    10-inch Rough-in Toilet Buying Guide

    Types of toilet

    After deciding that you want a 10-inch rough-in toilet, the next step is to decide if you want a one-piece or two-piece toilet. One-piece toilets are easy to clean and don’t hold dirt and mildew in the crevices. On the other hand, two-piece toilets are easy to install and usually cheaper.

    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 compact bathrooms, while elongated bowl designs are great for people who want a comfortable unit.

    Flushing system

    Having the right flushing system is important if you want to get rid of the waste easily and fast. Pick a toilet with an efficient and powerful flushing system. Different toilet models come with different flushing systems. Compare different flushing systems and select a toilet that clears waste once without using much water.

    Standard Dimensions of a 10″ rough-in toilet

    Bowl width: 14-14.5 inches
    Average bowl Height: 15 inches
    Bowl with a seat: 15.5-16 inches
    Total Height with the tank: 28-30 inches
    Distance from wall: 10 inches
    Tank width: 18-19 inches

    Water consumption

    After selecting a flushing system, you should also consider water consumption(1.6GPF or 1.28GPF?). Some toilets use more water than others. It is recommended that toilets use less than 1.6 GPF. But some toilets use less than this as there are those that only consume 1 gallon per flush and some 1.28 gallons per flush. If you want to save water, pick a toilet that uses 1.28 GPF or less.

    Ease of installation

    Not all toilets are easy to install. Some require the help of a professional plumber to install, while others can be installed with much ease. One-piece toilets are usually harder to install than two-piece toilets. This is because most of them are heavier.

    Ease of cleaning

    Don’t just look at the design and comfort of the toilet. But also, look at how easy it is to clean it. Some toilets have unique surfaces that don’t stick waste or particles on their surfaces. Such toilets are easy to clean. Pick a toilet that is easy to clean, as you’ve to maintain good hygiene.

    10″ vs. 12″ rough-in toilets: What are the differences?

    Most toilets come with a standard rough-in of 12 inches. However, a 10 Inch rough In is common in small bathrooms and old houses. The main difference between a 10-inch and 12-inch rough-in is that a 10-inch rough-in has the outlet opening closer to the rear drop passage than a 12-inch rough-in.

    Rough-in comparison10-inch12-inch
    Water consumption:MoreLess
    Compatibility:Compact bathroomsSpacious bathrooms
    Clogging issue:CommonRare
    Durability:Less durableMore durable


    Question: What features should I consider when picking a toilet?
    Answer: Whether you’re picking a 10-inch or 12-inch rough-in toilet, there are several features that you should look at for great and efficient performance. The features that you should consider include the type of bowl, type of toilet (one-piece or two-piece toilet), water consumption rate, the height of the toilet, flushing system, waste removal efficiency, and price of the toilet. These factors will help you to select a nice toilet that meets both your needs and demands. The best 10-inch rough-in toilets would not compromise on performance, water efficiency, or durability and would also ensure clog-free operation.

    Question: Do round and elongated bowls have the same inches?
    Answer: No, they don’t. Elongated bowl toilets are usually longer than round bowl toilets. Elongated bowl toilets are also 2 inches longer than round bowl toilets. As a result, they are more comfortable than round bowls. On the other hand, round bowl toilets are small and more suited for compact places or tiny bathrooms.

    Hi, this is Robert Crossan, the owner of this website, has 17 years of experience in the installation, maintenance, and repair of toilets and plumbing systems. After completing the Level 2 Basic Plumbing course in 2005, I started working in both domestic and commercial buildings as a professional plumber. So I can figure out the core difference between different toilet models and brands. It also helped me monitor their work performance and setbacks.


    1. Who knew that choosing a toilet was so difficult? Apparently, not me. Your website is great.

      I am struggling a bit to find a moderately priced 10in rough in, one piece toilet with a strong flush for my powder room. Do you have a recommendation? There is only one in this review and in the cons it says it isn’t comfortable for short people. I am a whopping 5’1 and the only person who lives in my home. Any suggestions you can provide would be greatly appreciated!
