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 operate throughout Greater Montreal, offering complete, custom, durable, and aesthetic renovations. With extensive experience, a professional team, and quality materials, we help you create a space that enhances your daily life... and the value of your home.

A bathroom renovation:
a strategic investment

In Montreal, the bathroom is one of the first rooms 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 elegant bathroom not only improves your comfort, but also significantly increases the value of your property.

Some improvements offer an excellent return on investment:

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

Results that stand out in the market

Our renovations aren't just beautiful: they're designed to please in the long run.


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 even installing new bathroom furniture, such as a vanity .


We know where to focus the effort to get 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 entire family or facilitate future resale.

When to renovate to sell at the best price?

For maximum value, we recommend planning your renovation a few months before listing.


In Montreal, spring and early fall are the best times to renovate, as they are also the busiest times for the real estate market.
