Best Dual Flush Toilet Options For Your Bathroom

Are you undecided on the best dual flush toilet option? This piece carries the right information by uncovering different dual flush toilet alternatives that are suitable for you. Many prefer to use dual flush toilets because they have a water-saving design, thereby lowering your monthly water bills. 

The purpose of this write-up is to teach you how a dual flush toilet works and offer you some of the best models in the market for your selection. In the end, you should pick the correct one and experience an exciting bathroom experience. Read on.

Buyers Guide of the best Dual flush Toilet option

Different manufacturers are flooding the market with various dual flush toilet models while confusing buyers on finding the best among all options. As a new buyer, you are responsible for gauging these toilets under different elements before deciding. This section uncovers some of those parameters to employ and help you separate fake from real.

Noise Levels

Some toilet models have a silent flush, while others produce a rumbling noise which can be irritating. Loud flushes are not convenient, especially when you are trying to sleep train your baby. As such, it could be reasonable if you settle for a toilet that has a muted flush. 

What makes a difference is the type of flushing mechanism. For instance, while others would want down jets or up jets, others would settle for cyclones or drips with different noise levels. Ensure that you settle for a correct toilet that can tolerate a suitable noise level without interrupting someone’s attention. 

EPA Rating

As per standard, companies should maintain a cistern capacity that is less than 1.6 gallons. You will get a certificate if you develop a toilet that supports 1.28 gallons or below on the condition that such a toilet flushes effectively since similar models may give poor service. 

If you treasure conservation, then it is reasonable to settle for a toilet with an EPA certification referred to as EPA WaterSense. Such toilets use less than 80% of the EPA recommended standard of 1.6 gallons. However, it is all about the number of flushes and not about cistern size. 

Some models use 0.8 gallons per flush, but they may need more than three flushes to eliminate solid waste. It is vital to find a good hardware store that allows you to test them before settling for the right pick. 

Mounting Position


Some models have cisterns hidden behind the wall, while others use a compressed tank for fitting in the back of the toilet bowl. In either case, you can still mount such toilets on the floor or the wall depending on the plumbing structure and the bathroom layout. 

Before you make a decision, assess the available floor space. For instance, floating wall-mounted toilets can make the bathroom appear bigger. However, one can still reinforce them with steel brackets. 

Some models can have their rear plumbing exposed, leaving awkward gaps and spaces for hiding dirt. You can overcome that by using a skirted toilet which is more hygienic and less distressing. 

Physical Requirements

The main toilet sizing issues are height and length. A toilet seat can be as small as 16 inches and as long as 20 inches to suit your preferences. Elongated seats have more than 18 inches to promote a more natural posture. In case you have smaller bathrooms, then a shorter seat is ideal for you. 

Another element that you must factor in is any height that should agree with other special groups’ needs. Such people may have back problems or be elderly hence need proper dimensions. If you have to purchase the seat differently, ensure that it can fit into the toilet perfectly. As a rule of thumb, measure the rough-in beginning from the baseboard. 


Materials dictate the lifespan of your toilet option. Most of the toilets come from durable porcelain construction. Your ideal toilet should have incredible material construction, which can be cost-effective. Any weak stuff that is prone to constant breakage makes your life more expensive. We recommend a long-lasting toilet coupled with material excellence. 

Flushing Mechanism

Many dual flushing toilets have an elaborate flushing mechanism to achieve effective and powerful flush with minimal water consumption. There are two main common flushing structures. First off, a pressure-assisted mechanism uses a mixture of highly pressured air and water. Such systems are costly and louder yet more powerful.

Another flushing mode is a gravity flush structure that is easier to use than normal pressure-assisted flush structures. Such a system functions by using gravity for the water weight to produce a flush. These systems happen to be much quieter and save more water. 

Pricing and Warranty

You must access your pocket before you purchase a suitable toilet for you. You can do so by performing further research to establish better brands with timely services to meet your expectations. If one is on a limited budget, you should go for lowly priced items. If money is not an issue, you can settle for the one that deems fit for your needs. 

A warranty speaks volumes concerning the quality of an item. Longer warranties can exceed five years. Consequently, other alternatives have limited warranties that never go beyond two years. Understand the terms before buying the toilet.
