How to Choose a New Toilet for Your Bathroom

How to Choose a New Toilet for Your Bathroom | Diary of a DIYer

Choosing a new toilet for your bathroom isn’t at the top of anyone’s fun-things-to-do list. But it’s an integral part of your bathroom, and there are surprisingly a lot of different options for toilets out there. Do you want a powerful flush? A comfy padded seat? The choices are endless.

Whether you’re replacing an outdated toilet or choosing a toilet for your newly built home, here are a few things to think about.

Style: Traditional or Modern?

The two most common toilet styles are one-piece toilets and two-piece toilets.


One-piece toilets are a great option if you’re looking to add a contemporary flair to your bath. Since these toilets are seamless, they’re a bit easier to clean than their two-piece counterparts. Installing a modern one-piece toilet in your bathroom will come at a cost as they tend to be the more expensive option.


On the flipside, two-piece toilets are exactly what they sound like: they come with a tank and a bowl. They’re more economical than a one-piece toilet, giving you more money to spend on “accessories” like different styles of toilet seats and tank levers.

Once you decide on a toilet style, you’ll need to keep some measurements in mind—one being the rough-in. The rough-in is the distance between the drain in the floor and the wall. Know this measurement before taking the plunge into buying a new toilet; otherwise, you’ll need to rework the plumbing.

Toilet Bowls


If your bathroom is short on space, choose a round toilet bowl. It’ll save a couple of inches for walking room. Elongated toilet bowls offer more comfort, but like the name suggests, they take up about two extra inches of space in your bathroom. As always, measure first! You’ll want to make sure there will be enough room for opening cabinet doors and drawers.


Most standard toilets stand about 14 to 15 inches. Taller people and the elderly will find that toilets around 17 inches tall make sitting and standing a little bit easier. Taller seats mean a higher price, but it might be worth it if it’ll reduce back or knee pain. 

Flushing Systems

Gravity Flush

Gravity flush toilets use the weight of the water in the bowl to create flushing pressure. These toilets are a popular choice and are more cost effective than pressure-assisted toilets. You’ll spend less money up front buying the toilet, and if it needs repairs down the line, replacement parts are also fairly inexpensive.

Pressure-Assisted Flush

Toilets with pressure-assisted flushing systems are noisier and tend to be expensive than a gravity flush toilet. Despite the noisiness, pressure-assisted toilets provide a stronger flush which results in a cleaner bowl.

Water Efficiency

Updating an old, inefficient toilet can save you at least $110 a year. Low-flow toilets are required to use only 1.6 gallons of water per flush (compared to the 3.5 gallons in older toilets), so water efficiency shouldn’t be a problem. Federal requirements changed in 1994 and today, over twenty years later, some toilets use even less than 1.6 gallons per flush.


Choosing a toilet can be a lot more in-depth than what I’ve outlined in this post (like wall mounted toilets, high tank toilets and more). But with some basic knowledge, you should be able to make an informed decision when it comes to choosing a new toilet for your bathroom.
