Best Rear Outlet Toilets

A rear outlet toilet has a lot of benefits. They’re relatively non-invasive, and you can install them without damaging your bathroom floor.

They’re often made with a sleek design, providing some crisp, clear lines to a modern bathroom aesthetic. They’re cheaper to install as well since it’s easier to plumb directly through a wall than to work out a system beneath the toilet.

So, with a lot of people opting for a rear outlet design for their renovations, you’d assume there’d be a wide array of products available, giving you a massive amount of choices for your new bathroom.

Sadly, that’s just not the case. These sorts of toilets are greatly outnumbered by their floor-plumbed partners and can be incredibly hard to find.

Our Top 5 Best Rear Outlet Toilets Reviews

1. Swiss Madison Well Made Forever Ivy SM-WT450

Swiss Madison Well Made...

Protecting your perfect bathroom flooring at our number one spot is an elegantly designed toilet that is sure to impress even the hardest-to-please pooper.

Let’s start with the most striking feature of this toilet. It’s not only a rear access design but the whole lower unit is fitted to the wall with no base.

This gives it an amazing floating look that makes the room seem far more spacious.

Not only does it save space by refusing to make contact with the floor whatsoever, but the whole tank system is also fitted inside the wall cavity. This means that all there is on show is the awesome floating seat.

If you’re reading this and thinking…well how the hell am I supposed to flush? The flush functions are accessed from the panel that sits flat against the wall about half a meter above the toilet.

It also has a dual flush design, saving you a ton on your water bills. Some customers claimed the flush could be stronger, but they were content nonetheless.

This seamless design couldn’t be easier to clean because there are simply no awkward shapes, ridges, or hidden nooks.

It’s all there on display, sleek and minimalist. You can also expect a quick-release, soft-close toilet lid.

This is the perfect space-saving toilet for a more compact bathroom and is sure to free up some of that valuable space for other important design, practical, or decorative purposes.

What’s better is that it comes with all the nuts and bolts required for installation.

Pros
  • Elegant floating design mounts straight to your wall
  • Dual flush system
  • Tank is completely hidden in the wall
  • Flush system accessed via very neat panel on the wall
  • Saves lots of space
  • Has a sleek modern aesthetic
  • Quick-release, soft-shut lid
  • Comes with everything you need for installation
  • Super easy to clean
  • Affordable
  • You could have it set to custom height
Cons
  • Could do with a stronger flush
  • Some people found it quite difficult to install

2. Saniflo SaniAccess3 Macerator Pump with Elongated Toilet

Saniflo SaniAccess3 Macerator...

Disposing of all the bad stuff discreetly out the back, our second pick doesn’t just hide the evidence, it completely destroys it.

This Saniflo toilet has both a rear outlet and upflush design that is perfect for bathrooms below or far away from the sewer line.

The tank comes with a motor that powers stainless steel macerating blades at 3600 RPM that slice all waste up into slurry for easy transportation from thereon out.

This is a really advanced system that pretty much makes blockages beyond the U-bend impossible.

The powerful upflush function of this toilet means you can safely pump waste away from a maximum of 15 feet below the sewer line and 150 feet horizontally. Pretty impressive if you ask us.

It does seem at first that such an advanced flush and tank mechanism may be little time and energy-consuming, but the whole process is over within 10 to 12 seconds depending on the discharge pipe configuration. This means having a powerful toilet doesn’t have to cost you an arm and a leg.

The toilet itself has a classic design but with the famous smooth edges associated with rear outlet units. There’s definitely more surface area to cover here than on our first pick, but the lack of angles still makes this toilet a breeze to clean.

This gravity-defying, waste-mulching, samurai of a toilet is pretty pricey, but it’s capable of some amazing things. It could make spaces you thought couldn’t have a bathroom completely habitable.

Pros
  • Classic design with nice rounded surfaces
  • Stainless steel macerating blades turn all waste into slurry for easy disposal
  • Uses minimal amounts of energy
  • Both uplush and rear outlet functions
  • Blades make deep blockage impossible
  • Comfortable elongated design
  • Perfect for basement rooms or loft conversions
  • Can transport waste from 15 feet below the sewer line
Cons
  • Really pricey
  • Not as sleek as other designs

3. Kohler K-6299-0 Veil Wall-Hung Elongated Toilet Bowl

KOHLER K-6299-0 Veil Wall-Hung...

Classing things up at our number three spot is another floating toilet that will give any bathroom some extra space and extra grace.

With a very similar design to our number one toilet, this Kohler toilet has a completely wall-bound tank and a dual flush system that is operated via a slimline panel on the wall above the toilet.

The biggest difference here: the lines the toilet draws. Whereas the Swiss Madison toilet had a very typical bowl curvature to it, the Kohler’s lines have much more of a concave trajectory.

Much like the other picks, this toilet should be effortless to clean. It has an even smoother finish than our top pick, meaning you'll need a couple of antibacterial wipes here and there and you’re done. It’s also a really comfortable toilet to sit on thanks to the compact elongated design. 

The really impressive thing about the Veil is that all the mounting hardware is completely hidden from view by elegant paneling. This definitely gives off that much-desired seamless look.

Considering this toilet costs around twice as much as our number one pick and the functioning is almost identical, we feel it’s not exactly a good value for the money.

If, however, you appreciate these expensive little cosmetic differences, this toilet could be the one for you.

Pros
  • Elegant floating design
  • Nice top hat style concavity
  • All fixtures are completely hidden from view, giving a seamless and clean look
  • Comes with all the mounting hardware
  • Dual flush system saves on energy
  • Comfortable elongated and compact toilet
  • Hidden tank saves a lot of space
Cons
    • Much more money for cosmetic changes
  • 4. American Standard Yorkville Pressure-Assisted Elongated Toilet Bowl

    American Standard 2878016.020...

    Fitting securely into the wall of our fourth spot is a classic toilet from a giant of the industry, with over a decade of service to the American bathroom.

    If you like your toilet with a bit of pedigree, then look no further. This American Standard rear outlet design is perfect for all of your sanitary needs.

    It’s a far more traditional design than our other picks, taking up more space, and includes some pretty heavily accented piping reaching towards the wall.

    Due to all the piping curves and pits, it’s going to be slightly harder to clean but not difficult. Due to the wall connection, there are no hidden or hard-to-reach areas around the back. The back is fully blocked off to hide the rear plumbing.

    Moreover, the EverClean surface of the vitreous china helps to prevent build-ups of dust, mold, mildew, stains, and odors, so you won’t have to clean quite as often. 

    It’s a single traditional handle flush system, but with the pressure-assisted function, it should be more than enough flush for anyone and save you money on your water bills simultaneously.

    Pros
    • Comfortable elongated design
    • Pressure-assisted flush makes up for weaker rear outlet function
    • Traditional design
    • EverClean surface keeps things sanitary with minimal amount of cleaning
    • Reputable brand
    Cons
    • Quite pricey
    • Takes up quite a lot of space
  • 5. Barrington Comfort Height Two-Piece Toilet

    Barrington Comfort Height...

    Our last pick is one for the eco-warriors out there who like to do their part for the community but still enjoy a little bit of luxury in the bathroom.

    Let’s take a look at the flush function first. The Barrington is kitted out with pressure lite flush technology that assists the weak aspects of the rear outlet design.

    It allows you all the benefits of a powerful toilet while limiting water waste.

    Each flush only uses a single gallon of water, which may not seem like enough, but it’s actually a really effective system that continues to shock customers.

    This is a toilet full of quirks, one being the left-hand trip lever. This might be a breath of fresh air for the lefties out there.

    If you’re tall in stature, you’ll really appreciate the height of this thing. It sits a fair bit taller than the average toilet, so no longer will you have to go number two with your ears boxed in by your knees. The elongated design also provides you with a bit of extra comfortability.

    This is a large toilet, but it’s incredibly slimline, so it won’t take up quite as much bathroom real estate as you’d think.

    It’s also one of the most expensive toilets on our list, but the hyper-efficient flush is going to save you a little bit of money annually.

    Pros
    • Works with one gallon of water per flush
    • Slightly taller build perfect for taller people
    • Comfortable elongated design
    • Left-hand trip lever
    • Powerful flush considering the amount of water it uses
    Cons
    • Expensive
    • Perhaps too large for a smaller bathroom

    Best Rear Outlet Toilets

    Budget

    It’s always good to drum up some sort of a budget before shopping for a toilet.

    It’ll vastly narrow down your search, especially when there's a pretty sparse market.

    Wall vs Floor Mounted

    This is both a question of space and style. Wall-mounted toilets tend to look far more elegant in a minimalistic, modern sort of way, whereas floor-mounted toilets give your bathroom that classic look.

    If saving space is essential for you, a wall-mounted toilet might be the way to go as their tanks are usually completely set into the wall.

    Only the toilet itself protrudes into the room. The space you save beneath isn’t particularly usable, but the light, airy feel it gives your bathroom is lovely.

    A floor-mounted toilet is probably going to be more secure than a wall unit, which is a nice attribute. You also have easy access to the inner workings if something were to go wrong. They can be quite imposing in a small bathroom though.

    You should also think about what kind of flushing system you prefer. A wall-mounted toilet usually uses a button flush panel installed in the wall above the toilet. A standard floor mount will probably have a normal trip lever.

    Standard vs Elongated

    Here’s another subject that brushes on both style and space, but it’s also a matter of comfort. Now, there’s nothing wrong with standard toilet shapes.

    They aren’t going to perform any better or worse, but some people feel that an elongated design is more comfortable as it offers you more room to sit.

    Unfortunately, you may only want to consider that extra comfort if you have the privilege of extra space as elongated designs protrude further out into the room.

    That said, they’re sometimes quite slimline designs. Installed in a corner, they might even save more space than a rounded toilet.

    Flush

    Water Usage

    Conserving water is generally important, but it’s more important to some people than others. If you champion this environmental issue, look for more efficient toilets. You should aim for a system that works with a gallon of water per flush or less.

    The average for older toilets is 2 gallons, and for modern toilets, 1.5, so with a hydro-efficient design, you could be doing your part to help the community and the world at large every time you go to the toilet.

    Pressure-Assisted

    If you’re serious about installing a rear outlet toilet, we highly recommend purchasing one with a pressure-assisted flush system.

    For all the practicalities a rear outlet toilet provides, they are known to have a weak flush. The extra pressure helps increase the strength of a flush without using excess water.

    Dual Flush

    A dual flush system is a great way to save water as you can choose the power of each flush, but keep in mind that due to the reduced power of rear outlet flushing, the lighter flush option will be very mild indeed.

    You’ll normally find dual flush systems as part of wall-mounted toilet designs as they aim for uninterrupted sleek lines. They do exist, but it’ll be harder to find a floor mount with a dual system.

    Height

    The height of toilets is never really discussed despite it being an essential aspect of its design and usage. It’s good to think about who’ll be using the toilet.

    If you have children, it might be worth looking for a shorter toilet, or if you’re particularly tall, it may suit you to look at larger designs.

    The average height of a toilet tends to be between 15 and 16 ½ inches, but you can find some that rise to around 19 inches, so no matter your height, there’ll be something out there for you. 

    Children below ten will likely need a toilet of 12 to 15 inches; however, bathroom step accessories could help them use a larger design.

    Teenagers are typically tall enough to use toilets of 15 inches or above. People that suffer from bowel issues may actually benefit from a much lower toilet as it forces a naturalistic position during defecation.

    Hypothetically, you could install a wall-mounted toilet at a height that suits you, although there might be some safety issues to consider.

    Installation

    The easier it is to install a toilet the better. It’s one of the best things about rear outlet toilets.

    Depending on your skill level, you may be able to install one of these toilets on your own, and if not, it’ll take a professional less time and keep costs down for you.

    Cleaning

    Rear outlet toilets tend to be much easier to clean as there are no hard-to-reach, hidden surfaces.

    Floor-mounted toilets tend to have a few more angles than wall mounts, making them slightly harder to clean.
