Turnkey bathroom renovation in Montreal: what does the service actually include?

A turnkey renovation refers to a comprehensive project managed by a contractor. The contractor does not necessarily carry out each task with their own team, but rather organizes and supervises the various professionals involved.

Depending on the nature of the project, this coordination may involve:

• the design of the new bathroom;

• site planning;

• demolition and removal of materials;

• plumbing and electrical work;

• ventilation;

• the preparation and waterproofing of surfaces;

• the laying of the ceramic tiles;

• the installation of the shower, bath and sanitary fixtures;

• painting, accessories and finishes;

• the final inspection of the construction site.

The homeowner therefore does not need to find a plumber, electrician, tiler, or installer separately. The contractor organizes the order of work and ensures its consistency.

1. Assessment of the existing bathroom

A successful renovation begins with a precise assessment of the space. Before proposing a new layout, it's essential to understand the constraints of the existing bathroom.

The entrepreneur is examining, in particular:

• the dimensions and configuration of the room;

• the condition of the plumbing and drainage;

• electrical installations;

• the existing ventilation;

• any traces of moisture;

• the condition of the floor and walls;

• the possibilities for moving equipment;

• the needs of the occupants.

This initial step helps determine whether the existing layout can be maintained or if a more significant transformation is desirable. It also helps anticipate technical difficulties that could impact the budget or timeline.

2. Designing a suitable layout

A bathroom should be aesthetically pleasing, but above all, it must be pleasant and practical for everyday use. The design aims to organize the room according to the occupants' habits, the available space, and the building's constraints.

The project may include, for example:

• replacing a bathtub with a glass shower;

• the installation of a walk-in shower;

• the addition of a freestanding bathtub;

• the creation of additional storage;

• the installation of a wall-hung washbasin unit;

• improving traffic flow;

• adapting the room for a person with reduced mobility;

• highlighting natural light.

BonBain offers a bespoke bathroom design service to integrate aesthetic choices, functional needs and technical constraints from the outset.

3. Defining the budget and scope of work

A turnkey renovation must be based on a clear project description. The bid should specify the planned work, the materials selected, and the services included.

The cost depends primarily on:

• of the bathroom's surface area;

• of the condition of existing facilities;

• of maintaining or relocating the plumbing;

• the type of shower or bathtub;

• the quantity and format of the tiles;

• furniture and plumbing fixtures;

• electrical work;

• of the desired level of finish.

Keeping the main fixtures in their original location can limit certain expenses. Conversely, moving a toilet, shower, or sink may require more extensive work on the plumbing and floor structure.

The goal is therefore not just to choose materials that fit the budget. It is also necessary to intelligently allocate the investment between the visible elements and the technical work essential to the durability of the room.

4. Demolition and site preparation

Once the planning is complete and the materials are available, the work can begin.

Demolition generally includes the removal of:

• sanitary appliances;

• from the shower or the bathtub;

• of the washbasin unit;

• old coatings;

• partitions or elements that have become unnecessary;

• materials damaged by moisture.

This phase sometimes allows us to discover problems that were invisible before the walls were opened: old leaks, mold, deteriorated piping, insufficient ventilation or weakened floor support.

In a turnkey service, the team also organizes the protection of passage areas, the removal of debris and the maintenance of a site that is as clean as possible.

5. Plumbing, electricity and ventilation

The technical work forms the foundation of the new bathroom. Even if it becomes largely invisible once the work is completed, it determines the safety and lifespan of the installation.

Plumbing may include:

• the replacement or relocation of water inlets;

• the modification of evacuations;

• the connection of the bath, shower, sink and toilet;

• the installation of the taps;

• preparing a walk-in shower;

• checking the flow and the seal.

Electrical work may involve lighting, protected sockets, illuminated mirrors, fans, or underfloor heating.

Effective ventilation is also essential to remove moisture and limit the risks of condensation, mold, and material deterioration.

BonBain coordinates these additional plumbing, electrical and ventilation works as part of its complete renovations.

In Quebec, work contracted out to a third party must be awarded to professionals holding the appropriate licenses. Electrical installations, in particular, must be carried out by a licensed contractor. The Régie du bâtiment du Québec (RBQ) specifies the applicable rules according to the type of property and the nature of the work.

6. Waterproofing and installation of coatings

A bathroom is exposed to water, steam, and temperature variations on a daily basis. Therefore, surface preparation should never be neglected.

Before installing the ceramic tiles, the team ensures that the walls and floor provide a stable, level surface suitable for a humid environment. Areas exposed to water, particularly the shower, receive an appropriate waterproofing system.

The ceramic tiles can then be laid on the walls, floor, or in accent areas. The tile size, alignment, grout width, and cut quality all greatly influence the final result.

This step requires precision, particularly around niches, taps, corners, drains and glass walls.

7. Equipment installation and finishing touches

Once the surfaces are ready, the bathroom gradually takes its final form.

Recent work may include:

• the installation of the shower or bathtub;

• the installation of the toilet;

• the installation of the vanity unit and countertop;

• the connection of the taps;

• the installation of the light fixtures and the mirror;

• the installation of the glass walls;

• painting;

• the installation of accessories;

• the application of the finishing joints.

A final check allows us to verify the operation of the equipment, the flow of water, the watertightness of the connections and the overall quality of the finishes.

What are the advantages of a turnkey service?

The main advantage is the simplicity of management. The owner does not have to organize the interventions himself or solve the coordination problems between the different professionals.

• an overall vision of the project;

Frequently asked questions about turnkey renovation

Does a turnkey renovation include the materials?

This depends on the scope of the service and the quote. The materials, sanitary fixtures, furniture and accessories included must be clearly specified before the start of the work.

Can certain elements of the bathroom be kept?

Yes. When their condition and the new layout allow, some equipment can be retained. However, this decision must be made after a technical assessment of the room.

Do you have to leave your home during the renovations?

This is generally not necessary when another bathroom remains accessible. However, you should expect noise, dust, and a period during which the renovated room will be unusable.

Why choose a single point of contact?

A single point of contact centralizes decisions, coordinates the various trades involved, and monitors the project's progress. This ensures the owner knows exactly who to contact throughout the entire renovation process.
