The American 270AD001.020 Cadet 3 might be a good bet if you want to fix an elongated bowl toilet in a tight bath.

The fixture measures 31.5 in by 34 in by 19.25 in and is made of vitreous china for durability. This commode maxes out on comfort by combining an elongated bowl with the ‘right height’ (similar to comfort height).

The American Standard 270AD001.020 Cadet 3 has an impressive flush rate of 1.28 GPF and might, therefore, be available in most States and cities that approve HET toilets only.

It also has American Standard’s EverClean surface. This prevents debris from sticking to the walls. It also protects your toilet from mold and mildew growth.

Worth noting is that this commode is ADA compliant too which is a good thing if you to add value to your property.

2. Renovator’s Supply Dual Flush Corner (round bowl) – Premium Pick

Renovator’s Supply Dual Flush Corner

Dual Flush Toilet

Renovator’s Supply isn’t a name that shows up in most toilet discussions. However, their white porcelain corner toilet is making a good rave among homeowners struggling with small bathrooms.

This toilet is a few inches smaller than the American Standard 270AD001.020 Cadet 3 at 29″ H x 17-1/4″ W x 30″. Its round bowl design suggests that it might give you a little more legroom.

Importantly, this is a dual-flush toilet. It uses 1.6 gallons for solid waste and 0.8 gallons for liquid waste. This might save you a few hundred dollars on your water bills annually. It also has the reno-gloss finish to prevent scratches and stains.

Space Saving Toilet

Renovator’s Supply Dual Flush Corner

If your bathroom could accommodate an elongated toilet without looking overly congested, then Renovator’s Supply Elongated toilet might be your sweet spot.

What we like about this version is that it combines an elongated bowl and a comfort height to make a toilet that most adults will use comfortably. Similar to its round-bowl sibling, this fixture also brings dual-flush performance.

So, you’ll not only be saving on space but also on your water bills. It also features Reno’s finish which does a good job of preventing stains and ugly scratches.

What about the price?

In my opinion, this toilet’s price is the lowest you can get for a toilet that offers an elongated bowl, comfort height, specialty finish, and a dual-flush system.

Best Corner Toilets Buying Guide

What to consider when shopping for a corner toilet:

  1. Rough In

    Corner toilets are not any different to conventional toilets. You will find that most of the rules that you need to keep in mind when buying a regular commode also apply here.

    Understanding the appropriate rough in that you need for your new toilet is a great way of narrowing down the available options. This also minimizes the inconveniences caused by trying to force wrong measurements to fit.

    Corner toilets come in 10’’, 12’’, and 14’’ sizes. If you are replacing a beaten fixture, you’ll want to go with the exact rough in.

    If you are either renovating a new bathroom or trying to fix a half bathroom in a tight space, you’ll want to measure the rough-in from scratch. It’s advisable to involve a professional plumber if you are not up to the task, and to avoid getting it all wrong.

  2. Water Efficiency

    With the increased Global Water Crisis, it’s a no-brainer that we all need to switch to water efficient toilets. Luckily, the market is full of water efficient systems that use 1.6 gallons per flush (GPF).

    Even better, the latest generation of toilets has taken the bar higher by minimizing the GPF rate to 1.28 which is 20% less than the standard rate. These are the models that come flaunting the WaterSense label.

  3. Flush Type

    Low Flush Toilets – these systems are also called High Efficient Toilets. They use utmost 1.28 Gallons Per Flush.
    Single Flush Toilets – they use the same amount of water for all types of waste.
    Dual Flush Toilets – these systems use a high amount of water for solid waste and a low amount for liquid wastes.

  4. Bowl Shape

    Elongated and round front bowls are the most common options for you. There is a heated debate on the issue of comfort in regard to these 2 bowl designs.

    Most people argue that elongated toilets are more comfortable. Whilst this is true to some extent, elongated toilets just don’t cut it where space-saving is paramount.

  5. Ease Of Cleaning

    Cleaning the bathroom is among a few other household chores that have the least volunteers. Unfortunately, this is also among other things that we have to do often.

    That being said, you might want to go for a toilet that cleans easily and stays cleaner for longer. Here are a few tips to help you here:
    • Go for commode with a powerful flushing system – this helps in cleaning the bowl and minimizing stains.
    • Consider whether the bowl has specialty surfaces (glaze) – most of these surfaces help in protecting the commode from molds, mildew, and bacteria.

  6. Consumer Response

    It’s easy to determine whether a certain crapper will look great in your bathroom theme simply by looking at it on the internet. But we cannot say the same regarding flushing performance. That’s where you need someone with firsthand experience about the item.

    Several online sites such as Walmart and Homedepot offer invaluable customer reviews and feedbacks that might help in making an informed decision.

Corner Toilets Installation

You could install a new corner toilet if you have some basic plumbing skills. In fact, if you’ve installed a conventional commode or replaced a toilet flange before, there’s nothing new to learn here.

8 Steps To Install A Corner Toilet

  1. Measure the rough-in and get a toilet that fits
  2. Bolt the flange and the wax ring (these 2 connect the toilet to the drain pipe). The flange also holds 4 anchor bolts that hold the commode on the floor
  3. Lift your toilet and fit it through the bolts. Press the commode down to create a seal with the wax ring
  4. Screw the nuts with your hands ensuring that the throne does not rock.
  5. If it is rocking, use some pennies or stainless steel washers at the base
  6. Use a wrench to tighten the nuts and place the bolt caps
  7. Apply latex caulk or tile grout around the base
  8. Connect the water supply and test the toilet

Installation is successful it there is no flooding/leaking around the base of the toilet after each flush.

Tips for making your petite bathroom look roomier:

  • Install a corner toilet and a corner sink
  • Ditch bright, exciting colors for pale and soft schemes
  • If possible, use a large mirror to ‘expand’ the bathroom
  • Position a counter over the toilet
  • Use large tiles with minimal grout lines
  • Use glass doors
  • Float the vanity
