Low-flush toilets

Low-water consumption toilets: economical, ecological and efficient in Montreal

Saving water, reducing your bills and doing something for the planet, all while enjoying modern and reliable equipment: this is exactly what low-consumption toilets allow.


At Bonbain Construction, we assist you in replacing or installing energy-efficient toilets, adapted to your bathroom and your habits.


Based in Lachine, we operate throughout Greater Montreal to offer you solutions that are effective, aesthetic and sustainable.

Why switch to a water-efficient toilet?

Significant reduction in consumption

Traditional toilets use between 9 and 13 liters of water per flush.
Current low-flow models use only 4.8 to 6 liters, and sometimes less with dual-flush technologies.


On an annual basis, this represents several thousand liters of water saved per household, without compromising on efficiency.

Savings on your bill

In Montreal, water is often included in municipal charges, but in certain homes (buildings, condos, co-ownerships with meters), reducing consumption can have a direct impact on operating costs.

A concrete gesture for the environment

Installing low-consumption toilets reduces pressure on drinking water resources, limits the need for wastewater treatment, and contributes to more responsible energy management.

What types of low-consumption toilets should I install?

Bonbain Construction helps you choose the model best suited to your space, your needs and your budget.

Dual flush toilets

They offer two buttons:

  • A small flush (2.6 to 3 liters) for liquids

  • A large flush (4.8 to 6 liters) for solids

It is the best compromise between performance and water savings, very popular in renovations.

Toilets with optimized siphon

Thanks to a more efficient evacuation system, these models offer a powerful flush with a reduced flow rate, even with just one button.

Wall-hung toilets

They are often combined with low-consumption built-in tanks.
They also allow for easy maintenance and save floor space.

Our installation services

Whether it is a complete renovation, a partial redevelopment or a simple replacement of equipment, Bonbain Construction takes care of:

  • Removing the old toilet

  • Installation of the new model (laying, connections, fixing)

  • Flow adjustment and leak test

  • Checking for proper evacuation

  • Cleaning and restoring the work area

We work with reliable suppliers who offer certified, durable toilets that comply with Quebec standards.

Is it a good investment for resale?

Yes. In Montreal, more and more buyers are choosing energy-efficient homes, including technical areas like bathrooms.


Low-consumption toilets are a small detail that makes a real difference during viewings and in the perception of the overall quality of the property.

We install low-consumption toilets in:

  • Single-family homes

  • Condos and apartments

  • Rental accommodation

  • Residences for the elderly or those with reduced mobility

And we adapt the installation to the constraints of each bathroom: available space, type of floor, access to the drainage system, desired aesthetic.
