Bathroom renovation in Montreal

Complete bathroom renovations in Lachine and throughout Greater Montreal

At Bonbain Construction, we transform bathrooms with care, rigor and creativity.


Based in Lachine, we serve the entire Greater Montreal area, offering complete, custom-designed, durable, and aesthetically pleasing renovations. With extensive experience, a professional team, and quality materials, we help you create a space that enhances your daily life… and increases the value of your home.

A bathroom renovation:
a strategic investment

In Montreal, the bathroom is one of the first rooms that buyers examine.


A well-executed renovation can recoup between 60 and 70% of its cost upon resale, depending on the market. A modern, functional, and stylish bathroom not only improves your comfort but also significantly increases your property's value.

Some improvements offer an excellent return on investment:

High-end materials such as quartz , porcelain , and designer faucets also enhance the appeal of your property on the Montreal real estate market.

Results that stand out in the market

Our renovations are not just beautiful: they are designed to please in the long term.


A neutral and modern design, durable equipment, efficient ventilation, optimized lighting… All these elements contribute to making your bathroom a selling point.

Even small renovations can have an impact: fresh paint, new light fixtures, modern faucets, replacing the mirror or installing new bathroom furniture, such as a vanity .


We know where to focus our efforts to achieve the best result at the right price.

Finally, adding a second full bathroom is a major way to increase a home's value. In Montreal, buyers are increasingly looking for homes equipped to accommodate the whole family or facilitate future resale.

When is the best time to renovate to sell at the best price?

For maximum value, we recommend planning your renovation a few months before putting the property on the market.


In Montreal, spring and early fall are the best times to renovate, as these are also the most active times in the real estate market.
