Fit Guide for WASHLET+ Systems & Integrated Bidet Toilets

Integrated bidet toilets and TOTO WASHLET+ systems are a great way to instantly upgrade both your bathroom and your personal hygiene. But before you purchase, you’ll want to make sure your new unit is the right size for your bathroom. In this comprehensive guide, we’ll walk you through the ins and outs of finding the perfect fit!

Floor Mounted vs. Wall Hung

When you hear the word “toilet”, what comes to mind? If you live in the United States, you probably think of a traditional floor mounted unit that connects to the drainpipe in your bathroom floor. If this style suits your tastes, great!

But if you’re looking for something a bit edgier, you’ve still got options. Wall mounted (also called wall-hung) toilets are growing in popularity thanks to their contemporary look and space saving design. While there aren’t a ton of residential models on the market yet, we do carry a few wall-hung integrated bidet toilets and WASHLET+ systems.

The wall hung integrated bidet toilets and WASHLET+ systems we sell are much more stylish than the spartan wall-hung toilets you’ve seen in public restrooms. Like their commercial counterparts, these residential models don’t touch the floor at all. Instead, they’re supported by a heavy duty metal frame installed inside the bathroom wall. The flush mechanism and tank are also concealed inside the bathroom wall.

So which is better, floor mounted or wall mounted? The answer really depends on your bathroom, your budget, and your accessibility needs.

  • Space
    Because their tank and flush mechanism are hidden inside the bathroom wall, hung toilets take up less space than floor mounted toilets. This makes them a great option for bathrooms that are tight on space. In fact, many wall-hung models save up to 9″ of bathroom space!
  • Installation & Cost
    Installing a floor mounted toilet is pretty straightforward, and many people choose to do it themselves. Even if you hire a plumber, it’s generally a quick and simple job that won’t add too much extra cost. In contrast, wall hung toilets are more expensive to purchase and install compared to floor mounted toilets. Installing a wall hung toilet usually require some serious bathroom renovation including work on your walls and floor. Unless you’re experienced in doing bathroom remodels, we recommend hiring professional contractors to do the work.
  • Accessibility
    Last but not least, you’ll want to consider what type of toilet will be easiest for you to use. Most floor mounted toilets have a seated height between 15″ and 17-5/8″. Most of the wall hung toilets we sell can be installed anywhere between 15 and 19″, giving you the flexibility to choose what’s best for you. As a general rule of thumb, the taller the seated height, the easier it is to get on and off the toilet.

    If you’re looking for an ADA compliant integrated bidet toilet or WASHLET+ system, we have lots of floor mounted options for you to choose from! When it comes to wall hung models, we only carry two ADA compliant integrated bidet toilets at this time: the TOTO Neorest EW and the TOTO Neorest AC. Currently, none of TOTO’s wall hung WASHLET+ systems are ADA compliant.

What is a Rough-In?

The rough-in is a measurement that only applies to floor mounted toilets. It refers to the distance from the wall (behind the toilet) to the center of the flange (drainpipe) in the bathroom floor. Most US bathrooms have a 12-inch rough in, so most toilets are designed for this measurement.

However, some bathrooms have 10-inch or 14-inch rough-ins. While integrated bidet toilets are only compatible with 12-inch rough-ins, there are a number of WASHLET+ systems that come in 10″, 12″ and 14″ rough-in options.

We recommend double checking your bathroom’s rough-in before purchasing an integrated bidet or a WASHLET+ system to ensure that your new unit fits the space. If you don’t have a toilet currently installed in your bathroom, measuring the rough-in is easy. Simply measure from the back wall of the bathroom to the center of the flange (drain opening) in the floor.

You can also measure around your existing toilet. To do this, locate the bolts holding your toilet to the floor. Most toilets only have two floor bolts, one on each side of the toilet. The distance between each bolt and the back wall should be the same. Measure from the wall behind the toilet to the middle of one of the bolt caps. If your toilet has four bolts, only measure to the center of the bolts closest to the wall.

Important Measuring Tips
Does your bathroom have baseboards or decorative tiling behind the toilet? If so, don’t include these in your rough-in measurement. Instead, make sure you start your measurement at the drywall itself.
Your measurement should come to 10″, 12″ or 14″. If your measurement is somewhere in between, round down to the nearest standard measurement or consult a professional.
Keep in mind that the shape of the toilet bowl has nothing to do with the rough-in. Whether your current toilet has a round bowl or an elongated bowl, you’ll still need to measure the rough-in using the steps outlined above.
Are the bolts holding the toilet to the floor tight and centered? If so, you can measure the rough-in with confidence. If they’re not properly centered, your rough-in measurement may be incorrect.
