Which Toilet Do Plumbers Recommend?

If you’re in the market for a new toilet and want to select one that is designed for plumbing health in Canada, this guide will provide the information you need to know before buying. The question that is most asked is: “which toilets flush the best?” After reading this, you will have enough toilet “know-how” to shop with confidence. You will still want to check in with your plumbing service beforehand, as they may have additional insights about your specific needs.

Whether you’re replacing an old unit or planning a bathroom renovation, choosing a plumber-recommended toilet is a smart investment. In Canada, features like eco-friendly flushing, quiet operation, and performance in colder climates are worth considering. Our plumbing experts have worked with many of the top-rated toilets in Canada, and we’re here to help you make an informed choice.

According to Consumer Reports, there are three primary areas to consider before even thinking about which features you want to include: performance, water-saving, and toilet size.

Performance

How well does it flush? What happens if your child throws an item in the toilet that is too small to retrieve, but large enough to cause performance issues? Will the toilet still flush? Will you have to call a plumbing company to come out to fix it? The best toilets are able to handle the worst clogs. Plumbers often recommend high-performance toilets that are clog-resistant and plumbing-friendly. Some of the best flushing toilets in Canada are designed specifically to handle large waste without clogging.

Water-Savers

There is a common concern that water-saving toilets do not use enough water to perform properly. Yes, they are designed to achieve the same clean bowl as the older models, which are considered to be the biggest water wasters in homes. Low-flow toilets use around 1.6 gallons per flush versus their older counterparts, which use up to 7 gallons per flush. If you’re looking for eco-friendly toilets in Canada, this is the way to go. The best low flush toilets in Canada are designed to conserve water without sacrificing performance.

Toilet Sizes

Buying the right size toilet for the allotted space is just as important as performance and water-saving abilities. It sounds like an obvious checkpoint, yet many toilet shoppers assume all toilet sizes are the same. Toilet height is also important. The higher the toilet, the easier it is to get on and off, with the exception of small children. According to Toilet Guides, manufacturers are making “toilets more compact while retaining space and comfort.” If you’re unsure, consider referencing a Canadian toilet sizing chart or consult with your plumber.

Toilet Flushing Mechanisms

The two main types of toilet flushing mechanisms are gravity-feed and pressure-assisted toilets. Pressure-assisted toilets flush by using a combination of water and pressurized air. Typically, there is a compression tank inside of the water tank which helps create more force. Gravity toilets use gravity to force the water and waste down into the trapway and then to the sewer pipes. Gravity toilets are easier to repair, while pressure-assisted models are more powerful. Many of the best dual flush toilets in Canada now incorporate both of these technologies for optimal performance.

One- or Two-Piece Toilets

Most homes have one-piece toilet models, possibly because they fit into smaller bathrooms more easily. But both designs have pros and cons that will make your decision easier to make:

• One-piece toilets are generally smaller than two-piece models.
• Easier to install in compact spaces.
• Easier to clean with fewer crevices.
• Two-piece models are more affordable.
• One-piece toilets are more durable due to their enclosed design.

If you’re searching for the best one piece toilet in Canada, consider models that combine compactness with ease of cleaning.

Dual-Flush vs. Single-Flush

Dual-flush technology has been used in several countries for decades, as water conservation and old plumbing have been important concerns. Manufacturers in Canada are currently producing more dual-flush toilets as they become the latest trend.

Single-lever flush systems that are water-savers have an average flush rate of 1.28 gallons per flush (gpf). Dual-flush models use 1.6 gpf for the full flush, yet they average around the same overall water usage. If you want the best of both worlds, consider a top rated dual flush toilet that offers power and water conservation.

Plumber Recommended Toilet Brands in Canada

When it comes to toilets that plumbers recommend, some brands consistently stand out for their reliability, flushing performance, and ease of maintenance. These include:

• TOTO – Quiet flushing and long-lasting components
• American Standard – Wide range of water-efficient toilets
  
• Kohler – Sleek design and touchless flush technology
• Gerber – Great value and affordable toilet installation
  

If you’re comparing the best toilet brands in Canada, start with these trusted names.

When Should You Replace Your Toilet?

If you’re experiencing frequent clogs, leaks, or your toilet is more than 15 years old, it might be time to upgrade. Newer high-efficiency toilets not only conserve water but can also lower your monthly bills. Signs it may be time for toilet replacement include:

• Cracks in the bowl or tank
• A wobbling or loose base
• Constant running water
• Discomfort or outdated style

Some of the best toilets in Canada in 2025 come with extended warranties and updated flushing systems, making replacement a smart long-term choice.

Other Considerations

If you’re exploring modern upgrades beyond traditional toilets, you might also consider adding a bidet to your bathroom setup. Bidets are growing in popularity across Canada for their hygiene and water efficiency benefits.

While we’ve covered the essentials of toilet-buying, there are additional features that may be important depending on your lifestyle. Plumbers can help you narrow down your options. Consider:

• Bowl Shape – Round-front, elongated, and compact elongated
• Trapway Type – Concealed, exposed, or skirted trapways
• Noise Level – Some models offer quiet flush systems
• Water Supply Line – Stainless steel flexible lines last longer
• Touchless Flushing – Great for hygiene-conscious or tech-savvy households
