When I was renovating my first home, I encountered some significant space issues in one of my bathrooms. The room barely had any space to move around in, making it feel cramped and tight. While bathrooms are utilitarian spaces, comfort is still important. My solution to the problem was to get a toilet with a 10-inch rough-in.

The best 10-inch rough-in toilet can do a lot to transform a tight bathroom. Those few extra inches of space in front of the toilet can make all the difference when it comes to comfort and interior design. Plus, you don’t have to sacrifice efficiency or functionality.

What Exactly Is a "Rough-In?"

First things first, let’s go over some basic toilet terminology. The rough-in refers to the distance between the finished wall and the floor drain for the toilet. It’s an important measurement to understand.

Generally, the rough-in distance is chosen long before the home is built. You’ll often find toilets with 10-inch,12-inch, or 14-inch rough-ins. Engineers will determine which rough-in is appropriate for the space. Installing a toilet and its appropriate plumbing may seem simple, but these fixtures need plenty of space around them to meet local building codes.

These days, 12-inch rough-ins are the norm. Most newer homes are built with this specification in mind. However, compact rooms can benefit greatly from a 10-inch rough-in. You’ll often see it in small powder rooms or older homes with smaller bathrooms.

If you’re unsure about your existing rough-in, just whip out your tape measure and record the distance between the wall and the toilet closet bolts. The closet bolts are located on the center of the waste drain and attached directly to the flange, so it’s often used to determine rough-in measurements.

It’s important to remember this measurement. You cannot use a toilet that’s not appropriately fitted for your rough-in plumbing. The waste drain on 12-inch toilets will not align properly with a 10-inch rough-in and vice versa. You can move the location of the drain to accommodate 10-inch rough-in toilets, but it will cost you a pretty penny.

The Benefits of a 10-Inch Rough-In Toilet

The biggest benefit that the best 10-inch rough-in toilets can give you is space. If might not seem like much, but those couple of inches can make all the difference in a tiny bathroom. This is especially true when you’re struggling to meet building codes. The required space in front of a toilet varies by jurisdiction, but most toilets must have at least 21 inches. A 10-inch rough-in can help you pass the inspection with flying colors.

When it comes to installation, 10-inch rough-in toilets are pretty much the same as standard models. There are no complicated additions to worry about. Installation is done the same way and can be completed with just a few simple tools and some know-how.

Furthermore, performance isn’t hindered in any way. Modern toilets are quite efficient and you can easily find models that have water-saving features. So, your upgrade may help you save some money in the long run.

How to Choose the Best 10-Inch Rough-In Toilet

Your new toilet is an investment that you’re going to be using every day for years to come. It’s important to take some time and careful consideration when choosing the right model.

If you don’t want to make a purchase you’ll regret, think about the following features as you shop.

Overall Footprint

Beyond the rough-in measurements, you should consider the overall footprint of your new toilet. Just because the plumbing is a bit shorter doesn’t mean that the entire fixture will be smaller.

Luckily, there’s a great selection of compact toilets on the market. If you want to take up as little room as possible, you can go with a one-piece toilet. Usually, one-piece toilets are approximately 28 inches in depth. Many also have a thinner profile to make room on both sides.

One-piece toilets have the water tank built in. Thus, they can be a bit cumbersome to get into your bathroom. However, once installed, they make a noticeable difference in the usable square footage of your bathroom.

Bowl Shape

Next, it’s good to think about the shape of the bowl and the corresponding seat. You have two options available. Standard round bowls are great if you want to keep things as compact as possible. They have a roughly circular shape and a diameter of about 16.5 inches.

Elongated bowls are the alternative. The bowl and seat take on a stretched oval shape, thus using up about 2 more inchesof space. These bowls are considered to be more comfortable and stable.

Bowl Height

Ever consider how the height of the seat affects your comfort when nature calls? Well, now is the perfect opportunity to do so. The standard bowl height is about 14.5 to 15 inches off the floor. This is fine for most people. However, taller folks can benefit from “comfort height” models.

A “comfort height” toilet stands anywhere between 17 and 19 inches off the floor. These toilets are great for the knees and back, so it’s worth considering if you’re a bit taller than most.

Flushing Efficiency

The average person uses about 18.8 gallons of water per day for flushing. That’s approximately 30 percent of what the average household uses a day! Efficient toilets can help cut back on your consumption significantly.

Look out for the WaterSense seal of approval. This means that the toilet is specifically designed to use 1.28 gallons of water per flush or less. You can also go with a dual-flush toilet, which allows you to control the amount of water you use with each flush based on your needs.

Style

Finally, there’s the style of the toilet. Most people don’t give the toilet a second thought when it comes to interior design. However, it’s a major part of your bathroom. Why not get a stylish option that you like to look at every day?

Modern toilet manufacturers have come up with some great designs in recent years. There are skirted models that are easy to clean, modern units with sleek lines, and more intricate fixtures with plenty of fine details. The sky’s the limit, so go with a toilet that complements your existing decor.
