Renovating a bathroom can't be improvised. In Montreal, as elsewhere, such a project requires organization, rigor, and a thorough understanding of the various steps. Whether you want to modernize an aging room or completely redesign the layout, here's an overview of how a successful renovation works.
Needs analysis and assessment of existing situation
Before considering tiling or faucets, it's essential to define your needs: number of users, available space, desired comfort level, and technical constraints. This first step allows you to establish a precise diagnosis of the current state of your bathroom.
Design of the new plan
Once the needs have been identified, it’s time to design. This phase includes:
The creation of a new development plan
The choice of equipment (shower, vanity unit, lighting, etc.)
The selection of materials and finishes
At BonBain, we help you design a functional, aesthetic bathroom that is adapted to your needs .
Preparation of the site
Before starting work, certain checks are required:
Do you need a permit? (plumbing or electrical modifications, for example)
Is the accommodation occupied during the work?
Are there any deadlines to respect (co-ownership, delivery deadlines, etc.)?
This step aims to anticipate logistical constraints and plan the intervention of each trade.
Demolition and structural work
This is the concrete beginning of the renovation. This phase may include:
Demolition of existing facilities
Plumbing, electrical or ventilation work
Renovation of walls, floors or ceilings
We ensure compliance with the building standards in force in Quebec, while limiting nuisances as much as possible.
Installation of coverings and equipment
Once the structural work is finished, it's time for installation:
Tiles, paint or wall panels
Shower or bathtub
Furniture, mirrors, lighting and accessories
This is the step that brings the project to life and reveals the style of your new bathroom .
Finishing and cleaning
Finally, we make the necessary adjustments, finishing touches and complete cleaning of the site. The final result must be clean, functional and ready for use .
