Best 10-Inch Rough Ins

Most people’s hearts drop as they pick up their tape measure and realize that they need a 10-inch rough in toilet. 

Why? 

Well, if they’d done their measuring and found out they needed a 14-inch rough in toilet their life would be easy. They’d simply have to hop into their car and drive along to their local toilet supplier. At their warehouse, they’d have a choice of dozens of 14-inch-ers and they could leave with one that same day. 

If they needed a 10-inch the story becomes very different. Most suppliers stock one 10-inch rough in, some don’t stock any. Their next couple of weeks will be filled with hard graft as they scour the internet for the perfect 10-inch rough in. 

Well, that would have been the case until we wrote this article.

Not only do we have a list of the best 10-inch rough ins on the market, but we’ve also got an exhaustive buyer’s guide and FAQ section too.

In a hurry? Here’s our top pick….

KOHLER K-3851-0 Cimarron Comfort Height Two-Piece Round-Front

KOHLER K-3851-0 Cimarron...

I know you’ve been told that the perfect 10-inch rough in toilet doesn’t exist. You’ve been lied to. Let us introduce you to the KOHLER K-3851 Cimarron, the answer to all your 10-inch rough in toilet-related prayers. 

If you want the aesthetic of a rough in toilet, but want to save some space (or some water) the Cimarron offers a rounded toilet bowl. This bowl is shorter than the traditional bowl, but it makes up for it by being nearly twice as wide (but it isn’t any wider than the rest of the toilet).

The bowl is smaller than a traditional bowl, but only by around 25%, in our opinion, its worth it for the amount of space saved. 

It’s worth mentioning that this unique shaped bowl will make it a little difficult to find a toilet seat that will fit this one. 

On the topic of water-saving, the Cimarron offers a dual flush feature, allowing yet more water to be saved. The dual flush offers extra power, which you may need with a smaller bowl. 

This toilet is not only a custom shape, but it is a custom height too. The average American toilet sits at 15 inches. The Cimarron sits at a mighty 17 inches.

The slightly higher seat means it’s easier to get on and off the toilet. A great choice for those of you with low mobility or bad knees.  

Pros
  • Comfortable height
  • Two parts fit perfectly together
  • Water-saving bowl
  • Left-hand flush
  • Dual flush
Cons
  • Doesn’t come with a seat
  • Water-saving bowl is quite small

Our Favorite Picks for Best 10-Inch Rough Ins

1. KOHLER K-3851-0 Cimarron Comfort Height Two-Piece Round-Front

KOHLER K-3851-0 Cimarron...

Our top choice for the best 10-inch rough in toilets is the K-3851-0 Cimarron Comfort from KOHLER. This is a uniquely shaped toilet, that really does offer something different from everything else on the market. 

The Cimarron has two unique features when it comes to its shape and size. Firstly, Cimarron has an unusually shaped bowl. This bowl is shorter than the traditional toilet bowl, however, it is much wider.

This has two major benefits - firstly, it saves a lot of water (we're always happy with smaller bills), and more importantly, it saves a lot of space. 

The rounded bowl means that the toilet doesn't stick out as far. This makes it a great option for those of you who want a powerful, traditional toilet, over a corner unit, but need something smaller. 

The second unique thing about this toilet is that it is taller than the average toilet. Where the usual toilet seat rests at 15-inches, the Cimarron sits at 17-inches.

KOHLER have developed their toilets to be taller as it makes them a lot easier to use. Particularly for people with low mobility. 

Another feature that we love about this toilet is the dual flush system. If you are interested in water-saving then it's worth investing in a toilet with a dual flush system.

This system means that the normal flush uses less than a gallon of water, and the full flush uses 1.8 gallons. This is much lower than the average American toilet. 

There are two minor flaws with the Cimarron. 

The ergonomically shaped bowl is a great idea. However, it is such a unique shape that you may struggle to find a seat to fit this model. 

Secondly, the water-saving bowl is small, which some people may have issues with. It does not have the capacity for a 'bathroom emergency'. 

These downsides are definitely worth it if you need to save space but don't want to sacrifice style. 

Pros
  • Comfortable height
  • Two parts fit perfectly together
  • Water-saving bowl
  • Left-hand flush
  • Dual flush
Cons
  • Doesn’t come with a seat
  • Water-saving bowl is quite small

2. Fine Fixtures Dual-Flush Round One-Piece Toilet 12" Rough in (Seat Included)

Fine Fixtures Dual-Flush Round...

While this is technically at 12-inch rough in, this toilet comes with the option to be installed as a 10-inch rough in. It's too good not to be included. 

This is another great option for those of you who are looking to save space in your bathroom. It is a low sitting toilet, with a slim body designed to fit snugly into nooks.

Some people will adore the compactness of this toilet, others will find it frustrating and too small to use properly. We noticed taller users complaining about the size of the toilet. 

This is another toilet that comes with a great, water-saving dual flush system. As we'll mention in our buyer's guide, we consider a dual flush system a must. They save so much water and really do make a huge impact on yearly water bills. 

This toilet does come with a high-quality, soft closing lid. The trapway (the inside parts of the toilet) are glazed, this helps prevent dirt from sticking to the sides of the toilet. This glazing will take one of the nastiest household chores off your list. 

The Fixtures toilet does suffer from two small flaws. 

Firstly, this toilet has a little bit of an infamous reputation online for having some of the worst installation instructions ever.

They're quite entertaining if you're not trying to install the toilet. If you do need to install this, there is now a video guide on Youtube. 

Secondly, as we mentioned above, this is a very small toilet that people taller than 5"8 may struggle with. 

Pros
  • Seat included - with soft-closing action
  • Glazed trapway
  • Dual flush
  • Petite
  • Both 12 and 10 inches rough in
Cons
  • Instructions are poorly worded (but online video available which is much easier to follow)
  • Hard to install
  • Small

3. TOTO Drake Elongated Bowl, Cotton White

TOTO Drake Elongated Bowl and...

This Drake Bowl from TOTO is a great option for those of you who already have a tank installed in your bathroom. As this is just a bowl with a fitted guard for a tank. This is one of the more expensive options on our list, but you really do get what you pay for. 

This is a sturdy, china toilet with an elongated bowl and thin tank guard. Its unique dimensions allow it to be installed in smaller bathrooms, without looking any different from a traditional toilet. 

This model comes with a power flushing system. Many of the toilets on this list have these; we have included them because they make cleaning the toilet so much easier.

This toilet also comes with a glazed trapway, another great way to keep the dirt off. Power flushing and glazed trapways are the dream combination. 

As we mentioned this kit only includes the bowl; it does not include a tank or a seat. The unusual shape of its bowl does make it a little difficult to source a seat that will fit.

If you are looking for a set with a tank, every other toilet on this list comes with one. 

Pros
  • Power flush
  • Fast filling bowl
  • Longer bowl
  • Glazed trapway
  • Longer and thinner tank cover
Cons
  • This is only a bowl (you will need a separate tank)
  • Doesn’t come with a seat

4. American Standard 2-Piece Elongated Toilet with 10-In Rough GPF

American Standard 221AA104.020...

This porcelain toilet comes at such a good price that we had to include this in our list. It's not often you need such a well-designed porcelain option that comes at a price to rival its plastic equivalent.

This is a classic looking rough in, but with a twist. The bowl on this toilet is longer than a traditional water bowl. This change in design makes this toilet a lot more comfortable to sit on.

It also means that because the model is thinner, it can be easier to install in a smaller bathroom, while still looking like a traditional sized toilet. Nothing looks out of proportion, which can often happen with cheaper toilets. 

This toilet is also fitted with a power flush system, designed to do the majority of the cleaning for you. One of the main complaints we've seen about this toilet is that the water level in the bowl is too low.

Introducing this power flushing system means that any staining caused by the low water level will be easily removed. 

Pros
  • Amazing price for a china toilet
  • Long, ergonomic bowl
  • Classic look
  • Easy to install
  • Power flush (does most of the cleaning for you)
Cons
  • Low water level in the bowl
  • Wears easily
  • Shows wear obviously
  • Long bowl

5. Swiss Madison Well Made Forever SM-1T254 St. Tropez One Piece Toilet

Swiss Madison Well Made...

For our final choice, we have picked out something a little unusual. The St Tropez is a classic, one-piece rough in with a boxy modern twist. It contains most of the classic rough in features with a few extra, unexpected additions. 

This toilet sits slightly lower than the national average. It claims that this makes it child and old people friendly. However, elderly people may struggle to get down to a lower toilet seat. What users will enjoy is the free, soft-close lid included with this toilet. 

This toilet comes with an angled trapway. This prevents dirt from attaching itself to the trapway, the angle also makes it easier to deep clean this toilet. 

The two main problems we have with this toilet are the flange holes and its over-enthusiastic flushing system.  

The flange holes on this toilet are both the wrong size and in the wrong position. If you possess a few DIY skills (and a big drill) you should be able to fix this yourself, but for the price, we would expect better… 

Our second issue with the flushing system: due to the angled nature of the trapway, when the flush on this toilet is used, a large amount of the water is sprayed back at the user. Although this can be solved by closing the lid, this toilet has a very steep and unpleasant learning curve.  

Pros
  • Blend of a modern and classic look
  • Angled trapway (for easy cleaning)
  • Seat included
  • Overenthusiastic
  • Low toilet seat
Cons
  • Low toilet seat
  • Flange holes are difficult to use
  • Over enthusiastic flush
  • Some people don’t like the look

Best 10-Inch Rough Ins Buying Guide

Below is a thorough guide to picking out the perfect rough in toilet for your bathroom.

We will be talking you through all the key choices you'll have to make when choosing your toilet, and important factors you should consider before making a final decision. 

What length of rough in do you need? 

The first step, measure your current toilet to work out what length of rough in you will need.

If you do not have one installed already, it is best to bring a plumber in to help you measure anything out correctly. 

Make sure you've measured your toilet correctly 

Why do you need to measure everything out so carefully? So, a mistake with a rough in purchase can be expensive. If the rough in is not the perfect size then you will not be able to install it. 

Get the measurement right to save yourself some time and money. 

What material should your toilet be made of? 

Secondly, you should think about what material you want your toilet to be made of. Your options are plastic or porcelain. 

Porcelain toilets are more sturdy. They take a lot less day to day wear and tear. However, they do chip. They are heavier and easier to clean. They are, however, at least twice the price. 

With plastic toilets, you do get what you pay for. The more expensive ones can rival even the best porcelain toilets. However, cheap options can be difficult to clean, flimsy, and wear very quickly. 

Do you have enough space? 

Rough in toilets are big; they are 10-inches away from the wall at the very least.

If you have a small bathroom then they may not be the best choice. If you have a small bathroom, you may want to look for a different type of toilet. 

On the other hand, if you find a rough in with a smaller bowl you may be able to make that work in a smaller room. 

Good lid? 

Most toilets come without a lid. 

However, there is often the option to pay a little extra to get a lid included.

If you are interested in this option, make sure to read the reviews to make sure this seat is worth paying extra for. It is not uncommon for manufacturers to put a low-quality seat on toilets like this. 

Dual flush? 

Once we got our first toilet with a dual flush we knew we would never go back. 

Not only do dual flush systems give you more control over how much power you use for every flush, it's also a great way to save water.

Not every bathroom trip requires full power, but it's nice to know you have the option if you need it. 

Frequently Asked Questions 

Here are the answers to the most common questions we get asked about rough in toilets. 

What is a rough in? 

A rough in is a type of toilet that is installed a small distance away from the floor piles.

They are visually appealing toilets that bring a lot of power and surface area, where smaller toilets cannot. 

Why is it so difficult to get hold of 10 and 12 inch rough ins? 

The average size of rough in toilet in American is 14-inches. For this reason, the 14-inch toilets are widely stocked online and in stores. 

Rarer sizes like 12-inches and 10-inches are therefore less likely to be held by suppliers. They are more expensive to produce as they are made on a smaller scale. They will either be more expensive for the customer or less profitable for the supplier. 

These are the reasons why 10 and 12 inch rough ins are more difficult to get hold of. 

How do I measure my bathroom's rough in? 

It is pretty simple to measure what size rough in you need.

Simply take your measuring tape and measure the gap between the wall and your current rough in. The gaps will be one of 4 - 10-inches, 12-inches, 14-inches, or 16-inches. 

Make sure to get this measurement correct as you will not be able to install an incorrectly sized rough in. 

Are rough in toilets good for small bathrooms? 

Rough in toilets are the best choice for medium to large-sized bathrooms. However, they are not always a great choice for small bathrooms. This is because rough ins are fitted quite a large distance away from the wall. Therefore, they stick out quite far into the room. 

Have a look at our number 1 choice - this rough in has a clever design that helps it save space. Otherwise, going for a corner toilet might be a better option for you.  

Are plastic rough in toilets better than porcelain?  

There are benefits to be found on both sides of this argument. 

Porcelain toilets are better for the environment, they are longer-lasting, and are a lot easier to clean. 

Plastic toilets on the other hand are a lot cheaper and are easier to install. They are also easier to find replacement parts for.
