List of in depth reviews


Those of you searching for short projection, with 24 inch depth, the GALBA isn't far off. It has a length of just twenty four and a half inches and it could be a sensible choice for consumers trying to save floor space in a compact environment.

It will fit a twelve inch rough in size, and has a one piece style which doesn't leave any gaps between the bowl and tank. This is a common area for germs to get into in two piece units so by removing this, it's one less thing to worry about.

The skirting around the bowl is certainly something that we're a fan of. It smoothes over any rough edges and gets rid of the trapway pipe lines, achieving a much cleaner, modernistic look.

But being small doesn't necessarily mean it can't pack a punch in clearing waste. The built in dual flush, vormax system sees to that, with an action that rinses the bowl throughly, leaving the surface clean for the next user.

It's finished in white, which is a sensible choice as it often matches other hardware in the bathroom. Dark themes aren't for us. The bowl is elongated too, which gives males the necessary seating space, and is generally seen as more comfortable than other bowl shapes on the market.

Swiss Madison Sublime II SM-1T257

Admitedly, Swiss Madison don't really have the same brand recognition as industry leaders like Toto and Kohler, but they make up for that by making sure their products are stylish with clean lines, and solid flushing technology.

The Sublime II collection is short depth, measuring an impressive 24 inches in length. It achieves this by having a unusually thin tank that sits quite close to the wall. But if you were expecting a round fronted bowl, you would be wrong. It even has a more comfortable, elongated shape that offers better leg support.

Looking at what sort of functionality it offers, we can see that there is a dual flushing system in place that helps you save water. In fact, looking at the figures and flow rate behind each, they are well into WaterSense territory with a 0.8/1.28 GPF.

There is a porcelain skirting around the edges, giving it a stylish look. Compared to models with trapways exposed, the skirting certainly improves the aesthetics. There are other small advantages associated with this too, such as the simplicity of washing it.

A quiet close lid and seat will be part of your purchase, and you'll also need to have plumbing in place for a product with a 12" rouh in. It's floor mounted and the full dimensions given by the manufacturer are 24 by 14 by 28 inches.

American Standard Colony 221DB004.020

We've looked at what the Colony range has to offer in the past and was impressed with what we found. It's made by American Standard, a big name that produces a number of different bath products. It is 25.8 inches long, wich obviously isn't the shortest option out there, but it may be a suitable alternative for those of you wanting to stick with well known, reputable companies.

It will fit a ten inch rough in depending on what option you choose. And will also be mounted to and have a waste outlet that will go through the floor.

Unlike the two above, this has differentiates itself through its design. It's two piece and features a round front bowl, maximizing the amount of floor space available. The material used to construct it is vitreous china which is smooth and doesn't take much effort to clean.

The trapway and flush valve both measure two inches, and the overall product dimensions given is 25.8 by 18.7 by 29.5 inches.

The flush mechanism in place has a powerful rim wash which gets to those difficult to reach areas that germs reside in. This system isn't the most efficient available, as it uses 1.6 gallons to clear waste from its bowl.

You'll also be able to find it in numerous colors, given consumers the chance to match their bathrooms theme. Linen, Bone, and White can all be found if you shop around. Be advised that this doesn't come with a seat. We recommend looking at the slow closing 5259B.65C.020 easy lift as a possible solution.

Other things to consider

As sanitary ware tends to be something that lasts many years before needing a replacement, you should be taking time to look into everything there is to know about a potential toilet. Listed below are a number of things to think about before making a decision. Having this knowledge will help you avoid buyers remorse and ensure you get something that you and your family are happy with.

Waste outlet - Look at the waste pipe, is it going through the floor, or do the pipes go through a rear waste outlet? Most modern households will have a floor based one which relies on the force of gravity to send waste to the sewage lines. But you'll need to double check this as rear flushing units require a different mechanism in place, usually known as air assist.

Trapway - If you have a similar taste in style to us, you'll appreciate what a skirted trapway design can do to a products aesthetics. Not only do skirted bowls look great, they limit the amount of areas which bacteria can thrive in. However, the extra materials used to construct these bowls tend to make them more expensive than those with exposed traps.

Mounting - How you choose to mount it is just as important. This can have an effect on a range of things including accessibility, ease of maintenance, and aesthetics. You're going to have two options available to you, those that are mounted to the floor and those that get mounted on the wall. We outline the advantages of wall hung toilets here. However, installing them can be quite complex for beginners.

MaP scores - Because Maximum Performance are a unbiased company, we often look at their flushing data to help us form an opinion of a specific products flush power. They have a scoring system in place that runs from 0 grams through to 1000 grams, o being the lowest score and poor quality overall, 1000 showing the highest levels of performance in handling bulk waste. It's a useful system, but shouldn't be used to tell the whole story.

Activation method - How you activate your flush really comes down to three different methods. The obvious and perhaps most common choices are both buttons and trip levers found in various locations on the tank. However, there is a third option that utilizes infrared sensors to detect a hand motion. This type of flush doesn't require users to physically touch a handle or button, they only need to wave a hand above the sensor.

Efficiency - Do you want something that handles waste well, but limits the amount of water it sends through the bowl? If so, a low flowing toilet could be a perfect choice for you. When you look at the volume if water that older units use, and compare them to WaterSense ones on our calculator, it's easy to see why these newer, more efficient units are preferable.

Gloss - It doesn't matter if you get yourself something with Everclean, CefionTect, or WonderGliss. The end goal of gloss is always the same, to smooth over the bowls surface and help prevent waste from sticking. This has a knock on effect in reducing and eliminating odors and limiting damage and staining to the bowl over time.

Seat - The seat situation varies from manufacturer to manufacturer. Sometimes they'll include a nice soft closing seat with their products, other times, you'll have to go and find one yourself. Just be prepared and aware of the additional expenses involved in buying a seat and the mounting hardware that comes with it.

If you have a bit of extra money set aside to spend, you should consider buying a bidet seat. These are a great option for those looking to improve hygiene, comfort, and convenience in bathroom visits. Why is this? Well, they have some interesting functionality built into them that enable users to spray their front and back with water. This cleans you up far more thoroughly than paper ever could. You may be thinking about getting dry, but the majority of these bidets come with built in dryers and heaters. Depending on the brand, they can also be equipped with a nightlight that lights up the bowl. It's an interesting piece of kit that is worth looking into in our opinion.

Supply line - Like the seating, you'll need to check if the water supply line comes with it. It may be that you already have one, but you'll still want to make sure and account for any additional costs involved. Such things can easily catch you by surprise and send you over budget.

Consumer feedback - Are there a lot of negative ratings and reviews? Is there any recurring theme among the complaints that indicate a common flaw? You can find the answer to these in the feedback sections of many shops and forums online if you look close enough. Time and time again, information can be found among them that highlight the red flags. This could be anything from leaks to bowls damage. But keep your eyes open, you'll save yourself a lot of time and effort, while avoiding the poor quality products.


Fitting a toilet with a 24 or 25 inch depth can have a big impact on the rest of the bathrooms layout. They don't extend far thanks to their short projection, leaving more space for home owners to add in a vanity, or even a shower. However, don't get caught out focusing on the length alone, there are plenty of other features that need to be looked into. Namely how much water it uses, how strong the flush mechanism is, and how comfortable it is. After all, you don't want to end up with a product that clogs easily or has poor durability.
