Best 11-Inch Rough in Toilets

Perhaps you don’t know this, but finding an 11-inch rough in toilet is not easy and when you do, it may be difficult to make a decision. That is why we have taken it upon ourselves to review some of the best 11 inch rough in toilets in the market.

1. Kohler K-3999-0 Two-piece Elongated Comfort Height Toilet 

The Kohler K-3999-0 Highline Comfort Height Toilet is a popular choice among consumers for its design, comfort, and water efficiency. Now, when we say “Comfort Height”, it means that this unit has a taller height compared to standard toilets. This feature can be more comfortable for individuals with mobility issues or those who prefer a higher seating position.

The toilet also features a two-piece design, with a separate tank and bowl. You will appreciate this because it means that this toilet is generally easier to install and maintain compared to one-piece models.

Another thing we found appealing about this toilet is its elongated bowl shape as it offers more space and provides additional comfort during use. We bet that you will find this bowl ergonomic and aesthetically pleasing.

2. DeerValley DV-1F026 Dual Flush One Piece Toilet

The DeerValley DV-1F026 Ally Toilet is a one-piece toilet that offers a dual flush system and an elongated bowl design. With this unit, you are looking at a one-piece design, meaning the tank and bowl are integrated into a single unit. One-piece toilets generally have a sleek and seamless appearance, making them easier to clean and maintain.

Moving away from that, this toilet features a dual flush system, which allows you to choose between two flush options: a partial flush for liquid waste and a full flush for solid waste. Dual flush toilets are known for their water-saving capabilities, as they offer different flush volumes depending on the type of waste.

Now, just like the previous unit, this one also comes with an elongated bowl shape which provides added comfort and roominess. You will realize that elongated bowls are more ergonomic and comfortable to use compared to round bowls.

Key Features

  • Efficient dual flushing

Just as the name implies, the HOROW HWMT-8733 Small Compact One Piece Toilet is designed for smaller spaces.  Its compact size allows it to fit into tighter areas while still providing the functionality of a standard toilet.

Another thing about this toilet is that it features a one-piece design, meaning the tank and bowl are integrated into a single unit. This will not only give you an easier time when it comes to cleaning and maintaining the unit but also when it comes to giving your bathroom a sleek and seamless appearance.

As if that is not enough, the unit boasts an efficient flush system. You will love this feature if you are looking to conserve water and save on your utility bills.

We love that the toilet comes with a comfortable seat that is ergonomically designed for user comfort. The seat is typically made of durable materials and may feature a soft-close mechanism to prevent slamming. If you or anyone in your house has mobility issues, this feature will come in handy.

Best 11-inch Rough-in Toilets Buying Guide

When buying an 11-inch rough-in toilet, there are several factors to consider to ensure a proper fit and optimal functionality. These include:

Rough-In Measurement

The most crucial factor is the rough-in measurement itself. Measure the distance from the finished wall to the center of the drainpipe to confirm that it is indeed an 11-inch rough-in. Make sure the toilet you choose matches this specific measurement, as toilets are available in different rough-in sizes.

Size and Design

Consider the overall size and design of the toilet. Ensure that it fits within the available space in your bathroom without obstructing doors, cabinets, or other fixtures. Double-check the dimensions of the toilet, including the height, width, and depth, to ensure a proper fit.

Bowl Shape and Comfort

Determine whether you prefer a round or elongated bowl shape. Elongated bowls are more common and often preferred for their comfort and extra space, but a round bowl might be suitable for smaller bathrooms or spaces with limited clearance.

Flushing Mechanism 

You want to look for toilets that offer efficient and effective flushing while using minimal water. Popular options include gravity flush, pressure-assisted flush, or dual-flush systems. Dual-flush toilets provide separate flush options for solid and liquid waste, which can save water in the long run.

Water Efficiency

Water conservation is a big deal in the world today. As such, you want to go for toilets that are water-efficient and have a low flush volume. Most modern toilets meet water-saving standards by using 1.28 gallons per flush (GPF) or less. Opting for a water-efficient toilet can help reduce water consumption and lower your utility bills.

Quality and Durability

Consider the quality and durability of the toilet. Look for reputable brands known for manufacturing reliable and long-lasting products. You may also want to check customer reviews and ratings to get an idea of the toilet’s performance and durability over time.

Installation and Maintenance

Think about the installation requirements and complexity of the toilet. Ensure that you have the necessary plumbing connections and expertise for installation. Additionally, consider the ease of maintenance and availability of replacement parts if needed.
