A trip levers location isn't the most important feature on a toilet. However, people have their preferences, and some of us want our flush handle on the right side of the tank. Unfortunately, this isn't the most common side, and that shows in the lack of choice versus those with a left hand trip levers.
Fortunately for our readers, we've found several options that look great and offer strong flushing performance. You can compare each of them side by side below.
The CST454CEFRG#01 us a low flow option (1.28 GPF) that's highly efficient and has the ability to save households up to twenty percent more water that 1.6 GPF flow rates. This makes it WaterSense certified too.
The 800 grams MaP score shows how effective it can be in removing waste despite using less water.
It has a tall bowl, which is both right height and ADA compliant. Plus the elongated shape makes sitting down more comfortable for users.

The CST454CEFRG#01 is almost identical to the Drake II that we reviewed here, the only exception being the location of its flush handle. This comes second in our best overall list too.
That doesn't mean it hasn't got weaknesses. For example, we prefer one piece over two piece in most situations as they are quicker and easier to install and clean. It also doesn't conceal its trapway. From a design perspective, we feel that by leaving the trap exposed, you're not maximizing how aesthetic it could be.
With the negatives covered, lets look at the positives. The first thing we noticed was that is't universal height, and includes the ADA compliant label. This added height makes sitting down on the bowl feel more like a chair.
Then there is its CEFiONITECT glazing that works with its Tornado flush system to rinse out the bowls surface thoroughly. It only uses 1.28 gallons and the force of gravity to achieve this.
The seat, wax ring, mounting bolts, and water supply line do NOT come with it. We recommend that you get yourself a slow closing option such as the SS224, SS214, or SS204 SoftClose seats.
Other than the handles orientation, the Highline brings some unique features to the table. It's two piece with a comfort height bowl, and it's finished in white.
Components that come with it include the K-4199 bowl, K-4468-RA tank, bolt cap accessory pack, tank accessory pack, tank cover, and lever.
The advantages of being comfort or right height include being more user friendly to people with mobility problems. That's why many of them meet ADA act design criteria. Add in the fact that it's elongated, and you can see it's built for comfort.
It has Class Five flushing performance, which ensures it removes waste easily with less chance of blockages. This class five system is single flush and gravity fed, and includes a large three inch flush valve and a direct fed jets to ensure water enters the bowls quickly. However, it's not the most efficient option on the market. This mechanism will utilize 1.6 gallons of water. In comparison to WaterSense options, you could potentially be using twenty percent more on average.
A common complaint used against two piece models is that they take longer to install. However, Kohler have a three bolt design that speeds the process up. This means that the bolts to attach the tank come pre installed.
It fits a 12 inch rough in, has a 2-1/8" trap passageway, and a water spot measuring 11-3/8" x 8". The seat will need to be bought separately. The K-4636 Cachet Quiet-Close and K-5588 Purefresh are recommended seats in the spec sheet.
If you would like a different color to the traditional white, this can also be found in biscuit and almond. To find these alternatives, simply search for the same model number with either a 96 (Biscuit) or 47 (Almond) at the end.
We've researched and analyzed the pros and cons of the Wellworth range in depth here. Lets go over the main features below.
The K-3987-RA-0 brings something different to your bathroom. It's dual flush, giving users a choice of a half or full flush. (1.1 and 1.6 gallons per flush respectively). It's still able to meet WaterSense standard due to the fact that you average out both. The 1.1 gallon flow rate is a lighter flush that's typically used for liquids. The 1.6 gallon one is specifically designed for the removal of heavier, solid wastes.
It's standard height, measuring 14-1/2 inches to the rim. The trap passage is 2-1/8 inches and the water surface area is 10-1/2 by 7-3/4 inches. It's mounted to the floor and will need to be installed on a 12 inch rough.
What's more, the bowl depth is quite shallow, with a 27-3/4" measurement from the back of the tank to the front of its bowl. This will help consumers with small washrooms save space for other sanitary ware and things like vanities.
Similar to the Highline, it has a class five system, which is powerful and sufficient for every day use in a residential setting.
Bowl depth and height - The depth or projection may not be high on your list of priorities if you've got a large bathroom space. But for those of you with a small room, space is a premium and you naturally have to make the most of what you've got. A shorter depth, measuring 25 inches or 26 inches in length are sensible solutions that offer a smaller footprint than your average toilet.
Just like depth, height is equally important. Except this time, the focus is less on saving space, and more on user comfort. Older products tend to have a standard height (15 inches) and these are generally suitable for the majority of users.
The question is, can you get something that's more comfortable and more accessible? We think so. Universal height bowls are at minimum seventeen inches high, and they max out at nineteen inches. This means there is less bending of the knees at the joint. This is why senior citizens, disabled, and tall people prefer them.
Rough in - The rough in measurement is the distance from wall, to the waste pipe that runs through the floor in floor mounted units. Our rough in guide will talk you through this process step by step.
Glazing - A key part of a toilets durability is found in the type of glaze on the bowl and tank. This is a form of protective coating that gets applied in the manufacturing process and will stop the build up of germs. In the long run, this can help stop the bowl from staining. It manages to do this through covering the pores within the porcelain. Bacteria is able to get into these pores on products without glazing, causing odors and potentially surface damage.
Toto have their own style known as SanaGloss and CEFIONTECT, which will form a ion-barrier, keeping things smooth and preventing waste sticking to the bowl after each flush. American Standard have EverClean, and Kohler are known for their CleanCoat which utilizes nanoparticles to keep things clean.
Alternative activation methods - The flush handle is undoubtedly a popular choice among consumers. But there are some great alternatives that are worth researching further.
One such example is a pull chain, usually found on high tank toilets. These have an unusual design and are not the most sensible option for your average home owner. But for those of you wanting something that's unique and different to other peoples bathrooms, they could work well.
You should also consider the user friendly design of buttons. These buttons are often used in dual flush mechanisms, being split into two for a half and full flush, but they are sometimes used for single flush models. For some people, pushing a button is more accessible.
Water savings - If you're able to get a eco friendly option, you stand to save many gallons of water over the products lifetime. The more people in your family, the greater the savings, both in terms of water and money on your utility bills. In fact, we've designed a calculator that lets you know roughly how many gallons you can save each year. If you're specifically looking for something economical, look for the EPA's WaterSense label. This will tell you that 1.28 gallons is the absolute maximum being used.
For those of you searching for a right side flush toilet, the chosen products above hold their own against the competition. Each were chosen based on our unique criteria that covers everything from bowl shape and external design, through to flushing power and water surface. But for those of you still unsure, we recommend that you read our other guides that can be found through our menu.
