Advanced toilet manufacturing technology has brought one piece toilets that combine the tank and bowl in a single unit. And they are creating a really good buzz.

However, despite their sleek and futuristic designs, these systems are yet to force the 2 piece toilets out of the circulation. These models have 2 major advantages over their one piece competitors.

First, you could replace each component separately in case of a mishap that left either the cistern or the bowl broke. Second, they are super easy to install.

If you are eyeing a 2 piece commode, let’s take you through the best models on the market today.

1. Toto CST454CEFG-01 Drake II – Editor’s Choice

Innovative Toilet

Soundly knocking CST744SL (read review) out of the number one slot is the Toto CST454CEFG-01 (read review). This is an innovative toilet solution designed to resolve most bathroom problems without wrecking your account.


Water Efficient Toilet

The most notable feature here is the double cyclone flushing technology. While G-max is regarded as Toto’s most powerful flushing system, it is no match to the Double cyclone in terms of water efficiency.

What the double cyclone system lacks in power, it makes up for it with a large computer designed trapway and sanagloss ion barrier glazing. This is a super smooth finish that makes the walls slippery to allow effective flushes each time.

This flushing system features 2 nozzles (instead of rim holes) that direct a larger amount of water to the siphon.

This hole-rim free design coupled with the sanagloss finish results to a more powerful flush that ensures water efficiency and improved bowl cleaning.

Powerful Flushing

What’s more appealing is that its polished chrome trip lever offers dual flush performance. This toilet’s powerful flushing design and excellent water efficiency make it a great choice for people who live in cities and States with low water supply.

Worth pointing out, this toilet does not come with a toilet seat. So, remember check to add one to the cart. On this note, our picks of the best-padded seats and bidet seats might give you important insights on the best models available today.

2. Kohler K-3609-0 Cimarron – Premium Pick

High End Appearance

While Toto is regarded as the giant in the toilet industry, Kohler always kills when it comes to design. If you are looking forward to remodeling your bathroom, our other list of Kohler products might have a toilet that will interest you.

KOHLER K-3609-0 Cimarron

6 Different Colors

The Kohler K-3609-0 Cimarron boasts a higher-end appearance with an aesthetically designed bowl and cistern. It comes in 6 different color schemes: almond, biscuit, black, ice gray, sandbar, and white that make it possible for every homeowner to get a perfect fit for their bathrooms.

The primary features that most buyers report include its comfort height, elongated bowl, and dual flush mechanism.
Its Aquapiston flushing technology is also among the leading flushing systems from Kohler. With proper installation, I bet you won’t find a use for your plunger.

3. Toto CST744SL-01 Drake – Budget Buy

TOTO CST744SL-01 Drake

Fantastic Choice For A Busy Household

We could sum up the Toto CST744SL-01 Drake toilet (read in depth review) in just one word: RELIABLE. Designed to resist clogs, this toilet might be a fantastic choice for a busy household especially where no one fancies the rather daunting task of unclogging a toilet.

This toilet features the G-max Flushing System that is currently the most powerful flushing system and uses 1.6 gallons per flush to clear the waste and leave the bowl clean.

Its elongated bowl and comfort height combo makes it a superb choice if your bathroom will be patronized by users with back pains that might be aggravated by a standard height throne.

Easy Installation

Its 2 piece configuration makes installation quite easy if you have the basic plumbing skills and you could replace it with about any other 12-inch rough-in toilet from any other brand.

Among other things, most of its buyers are excited by its quiet yet powerful flushes with quick refills and its ADA-compliant height.

Which Is The Best 2 Piece Toilet? – Final Verdict

Editor’s Choice


The TOTO CST454CEFG#01 Drake II. While all other toilets on this list have been rated as good flushers by most homeowners, the Drake II carries the day with its double cyclone flushing technology and sanagloss combo.

These 2 features coupled by the 3-inch wide flush valve and a large siphon jet ensure that stuff disappears. Most buyers report that they never pull the lever twice. Neither do they use the plunger any longer.

Basic Two Piece Toilet Buying Guide

Unlike a few decades ago, buying a toilet is no longer as easy as grabbing any model that catches your eyes first.

Toilets have evolved spontaneously. While there is a throne for everybody’s needs, it pays to research and to compare the available options in order to get a good system that offers reliability and good value for your bucks.

What makes a good 2-piece toilet?

Bowl Design

The toilet industry offers all sorts bowl designs. However, round, elongated, and compact elongated toilet bowls are by far the most popular. Square toilets are an option less popular.

Round – these bowls come in handy especially if you have kids around. They are slightly compact that elongated bowls and, therefore, consume less space in your bathroom. If you are buying a toilet for a petite bathroom, our list of the best round toilets might be a good place to start your search.

Elongated Bowls – true to their name, these bowls are 2-3 inches longer than round bowls. They are ideal for people with super size butts thanks to their wider support.

Compact Elongated Bowls– this is a blend of the first 2 options. The good news with these bowls is that they offer you a large sitting surface area without grabbing much space in your small bathroom.


The standard height for toilets is 15 inches. You might want to go with a throne with this height especially if you are of a short stature and if the toilet will be used by small kids.

The major problem with standard height toilets is that they tend to make back and hip pain worse especially when bending and getting up from the throne.

Comfort Height toilets to the rescue. These toilets have a height of between 17’’ and 19’’. They make sitting and standing easy and are friendly to most users especially the senior citizens, tall people, and those suffering from arthritis.

Take note though. The additional 2-4 inches can make the toilet seriously tall for some people. We’ve had some buyers ship their toilets back due to this. So, ensure that everyone in your household will be able to use it before buying.


Rough-in refers to the distance between the wall at the back of the toilet and the centre of the trapway outlet. 12-inch rough-in toilets are the most common today. Your plumber will advise you to go with one of these since they are readily available and super easy to replace.

Other options available are the 10 inch and the 14 inch. These are rare although they are still available in most old homes. A 10-inch rough-in toilet makes a superb choice if you are short of space or if you plan to put a toilet in locations where a 12 inch or 14-inch model won’t suffice, for instance, under stairs.
