Tankless Toilet Buyer’s Guide

Always be prepared to make adjustments as necessary, and find out what is required for installation ahead of your purchase. Failing to do so can mean the difference between a successful outcome that leads to years of satisfaction, and a regretful result that costs hundreds or more in repair and replacement costs.

Unit Size and Necessary Features

The size demands and necessary features of your toilet will depend on your personal budget as well as bathroom size. For smaller areas such as a garage or half-bath, it may make sense to invest in a smaller or narrower bowl size with fewer features than a full-scale unit tailored toward a master bathroom. Also, you’ll need to consider who will be using the unit, as well as how often to establish a solid idea of the most-desired features to include in your selection.

After knowing precisely what you’re looking for both in terms of what absolutely must be included, as well as what falls into the more “flexible” options list, choose from the best tankless toilets that offer your most significant needs while remaining inside your budget limitations.

Know Your Installation Concerns Beforehand

Failing to take full consideration of your installation limits and abilities when purchasing a new toilet is a great way to ensure disappointment. Many problems and overall dissatisfaction arise from not assessing the requirements and costs associated with a successful installation.

You may need to hire a professional, or for the DIY crowd, consult a manufacturer’s website or product manual before undergoing the process. Be sure that all necessary preparation is completed, acquiring any needed tools and knowing the circumstances involved with the installation process prior to making a full commitment.
