Rear outlet toilets are also referred to as rear discharge toilets or back flush toilets.

However, the name doesn’t matter as much as they might be a great boon to your bathroom renovation or your toilet replacement.

Rear outlet toilets are rarer in residential areas, but not uncommon.  There are houses all over that contain rear outlet toilets.  Despite the fact that they are less common, many people are pleased with how well they work.  There are also those that are displeased with them.  But this disagreement is expected.  Nothing can ever satisfy everyone all of the time.  Taking the time to look at rear outlet toilets might help you find a new way to approach your bathroom and how you would like it to look.

How Rear Outlet Toilets Improve Your Bathroom

Although you might have never heard of the rear outlet toilet, they are an excellent way to change up how your bathroom looks.  These toilets tend to have much cleaner lines and looks that make a bathroom look more modern look, while also hiding all of the pipes and connections that a typical toilet doesn’t. Installing one of these toilets is a sure fire way to really make your bathroom have a cleaner look about it.

There’s also another benefit to rear outlet toilets for appearance purposes that also helps with creating floor plans for your house.  Rear outlet toilets tend to be slimmer than standard showers.  While they aren’t so narrow that you can’t use them, this can save on space especially in bathrooms that are extremely tiny.

Besides the aesthetic appeal, there are some practical improvements that a rear outlet toilet will have over the conventional floor flushing models. In fact, many rear outlet toilets will have more flushing power than the floor flushing models.  Rear vent models have pressure aided devices in them that may make them more stronger than the typical floor flushing models that are getting installed now.

Back flushing toilets are also able to go in places that ground flushing models cannot. Sometimes, it’s just impossible to get everything just right for the floor flushing model.  In those areas, a rear flushing toilet will be better able to work with the floor and will be easier to install.  Not only will it be easier, but it will also be faster to install.  Without having to tear up the floor to get everything set, there will be a little less cost in that department.  This will also hold true for when you’re repairing the toilet.  Should anything go wrong, you just have to turn off the water, undo the connections, remove the toilet, and fix it or replace it.  This feature makes rear outlet toilets easier for those that fear issues with the bathroom.

If you happen to find a rear outlet bathroom that is completely wall mounted, and doesn’t have a support under the bowl, then you might conclude that it’s easier to clean your bathroom than you expected.  These models are so much more harder to find, though, so don’t get your heart set on it quite yet.

Why Rear Outlet Toilets Might Be Difficult

While rear outlet toilets might have some great things to offer anyone that wants to use them, there are a couple of hardships that come with acquiring and installing these toilets in a home.  In fact, you might not be able to find many models of rear outlet toilets.  The toilets aren’t made and sold as widely as the floor flushing models, so it’s just more harder to obtain them.  And it is often more expensive to get a rear outlet toilet than to get a floor mounted one.

And what you manage to find might be all that you can get.  There won’t be many options available for toilets like this.  You may not be able to locate nicer ones the same way that you can find standard toilets.  If there is already a rear outlet toilet installed in your bathroom, then replacing it can be more about finding something that is good enough than finding the perfect one.

Also unlike typical toilets, these rear outlet toilets will take a little more time and energy to install and replace.  Some connections and parts are not typical of floor flushing models, which means that it may just take more time before you can get that toilet installed. If you are not more mechanically inclined and don’t want to shell out the money for someone else to install it, then this process may be tricky and will involve a lot of research.  Some connections won’t seem obvious, and there will be parts that will seem odd.  If you’re in the mood for a real project, then it may be a good purchase.  Otherwise, you may want to avoid the rear outlet toilet.

Even after you have installed the rear outlet toilet, you may have to go back in and retighten some of those bolts that are holding your toilet in place.  Connected to the wall instead of the floor, it’s possible those bolts will loosen over time.  That can cause some serious problems, so many with rear outlet toilets will attempt to regularly tighten up the connections to ensure that nothing goes wrong.  The worst problem that can come with loose connections is water leaking.  This issue can cause severe damage over time, so if you want a rear outlet toilet, you’ll need to be aware of this possibility.
