Bathroom remodeling
The smallest room with the highest stakes
No room in your home concentrates as much technical work per square metre as the bathroom: plumbing, electricity, ventilation and waterproofing packed behind the finishes you see every day.
Kasa General Contractor remodels bathrooms across Montreal as a true general contractor: one team, one contract, one schedule covering design, demolition, certified trades, ceramic and final delivery.
Founded by two sons of immigrant builders, our family has spent 40+ years in construction and 12 years as general contractors, with 500+ projects delivered. We know exactly where bathrooms fail, and we build so yours will not.
Whether it is a primary ensuite, a family bathroom or a powder room, you make the decisions and we handle the rest: permits when required, subcontractors, inspections and delivery.
Who we work with
Bathroom projects for every home and every situation in Montreal
From a dated family bathroom to a spa-like primary ensuite, or a full rebuild after water damage, the process adapts to your project and your household.
What's included
What our bathroom remodeling service includes
Why professionals
Why trust your bathroom remodel to a licensed general contractor?
Water does not forgive approximate work. A bathroom done wrong shows up as leaks, mould and rot years later, usually inside the walls of the floor below.
Waterproofing done once, done right
Membranes, slopes and drains are the parts of the bathroom nobody sees and everybody depends on. Our crews execute them to code and we inspect them with you before they are covered.
Legal work above $2,000
In Quebec, renovation work above $2,000 must legally be performed by an RBQ-licensed contractor. Our licence 5797-3208-01 also gives you access to the RBQ guarantee plan from the moment you sign.
Certified plumbers and electricians
Supply lines, drains, GFCI circuits, heated floors and ventilation are handled by certified trades coordinated within the general contract. You never manage a subcontractor yourself.
A bathroom back in service, fast
Losing a bathroom disrupts the whole household. We sequence the trades tightly, order fixtures and ceramic early and give you a realistic schedule before demolition starts.
What sets us apart
Why Montreal homeowners choose Kasa General Contractor for their bathroom
Two generations of builders, one standard: built right, delivered as promised.
True turnkey, one point of contact
Design, permits when required, trades, materials, schedule and inspections all run through one team. You make the decisions; we carry the coordination from first sketch to final walkthrough.
RBQ licensed, APCHQ member, insured $5,000,000
Licence RBQ 5797-3208-01, APCHQ membership and $5,000,000 in liability insurance. Your project is protected legally and financially, including through the RBQ guarantee plan.
40 years of family craftsmanship
40+ years of construction in the family, 12 years as general contractors and 500+ completed projects. Bathrooms are unforgiving work, and experience is what keeps them watertight.
Transparent milestones, in your language
Cristian and Samuel walk the site with you at each critical step: rough-ins, waterproofing, ceramic, finishes. In English, French or Spanish, you always know where your project stands.
How it works
Our 5-step bathroom remodeling process in Montreal
A disciplined sequence where every hidden layer is validated before it disappears behind ceramic.
Free evaluation
Describe your bathroom by phone or through the form. We visit your home, measure the space, verify the condition of the plumbing and ventilation, and talk budget honestly before anything is promised.
Design and detailed quote
Layout, fixtures, ceramic and finishes are selected with our partner designers. You receive a detailed line-by-line quote. The $500 quote fee is deducted from your contract when the project moves forward.
Demolition and rough-ins
We protect the rest of your home, strip the room and run the new plumbing, electrical and ventilation. This hidden phase is inspected with you before anything gets closed up.
Waterproofing, ceramic and installation
Membranes and shower bases go in first, then ceramic, vanity, fixtures, glass and lighting in a coordinated sequence. Cristian and Samuel validate the critical details with you on site.
Delivery and warranty
Final walkthrough together, joint inspection and complete cleanup. Your bathroom is delivered with a 1 year labour warranty, manufacturer warranties and the protections of the RBQ guarantee plan.
Costs
How much does a bathroom remodel cost in Montreal?
Bathroom budgets vary widely because the room hides most of its cost behind the walls. Here is what actually drives the price, with real ranges rather than teaser numbers.
Plumbing and labour
The largest line in almost every bathroom project. Supply lines, drains, ventilation and waterproofing all demand certified trades, and their work is what keeps the room watertight for decades.
Fixtures and materials
Shower systems, tubs, vanities, ceramic, glass and heated floors. The spread between entry-level and premium fixtures is wide, and we help you put money where you will feel it daily.
Layout changes
Keeping the toilet, sink and shower where they are costs less. Moving them means opening floors and walls to reroute plumbing, which adds rough-in work and sometimes permits.

A word about $10,000 bathroom budgets
You will see ads promising complete bathrooms for $10,000. For a full renovation done to code by a licensed and insured contractor, that number is not realistic. It usually means skipped waterproofing, uncertified labour or corners cut where you cannot see them. We prefer to give you an honest number that still looks good ten years from now.

What Montreal homeowners say about Kasa Entrepreneur Général
Rated 4.5 out of 5 across 14 verified Google reviews.
Wonderful experience building our patio deck last fall. The job was done quickly with great attention to detail. Solid construction. And when I wanted a change to add a second staircase, no problem at all. Cristian listened and incorporated the new design I asked for. Job well done, I highly recommend Groupe KASA.
