The shower and floor drain

Shower and floor drains: a key element of bathroom renovations in Montreal

Often invisible, but absolutely essential, the drain plays a crucial role in bathroom design or renovation.

Whether it's a walk-in shower, underfloor heating, or simply equipment replacement, good drainage ensures efficient water removal, room durability, and above all, the prevention of leaks.

At Bonbain Construction, we ensure the installation of high-performance and suitable drains as part of bathroom renovation projects in Montreal and throughout Greater Montreal.

Why is the choice of drain so important?

The drain is responsible for carrying water away from the plumbing system. If it is improperly installed, the wrong size, or the wrong position, it can lead to:

Persistent humidity problems
Leaks in the floor or walls
Bad smells
Premature degradation of materials
And sometimes, significant structural damage

In the Montreal context — where many bathrooms are located in basements or older buildings — water management is a top priority to avoid costly repairs.

In what cases should a drain be replaced or a new one installed?

Here are the main contexts in which Bonbain Construction installs or replaces a drain in a bathroom:

Walk-in shower

The linear or central drain is integrated into the floor and requires a perfectly designed slope. The right choice of drain helps prevent water accumulation while blending aesthetically into the room.

Creation or replacement of shower

A new shower tray, a modern shower column or high-flow faucet sometimes require a drain with a higher flow rate or one that has been repositioned according to the new configuration.

Underfloor heating

Installing a floor drain is recommended to prevent any risk of water accumulation, particularly in Montreal basements, where the risk of infiltration is higher.

Bathroom in the basement

In many Montreal homes, basement bathrooms require a drain with a check valve to prevent backflow in the event of an overload of the municipal system.

The types of drains we install

Bonbain Construction offers several types of drains adapted to each configuration:

Traditional floor drain

Often centered in the middle of the shower, ideal for pre-formed shower trays. It is compatible with all ceramic tile styles.

Linear drain

Long, discreet, and elegant, it's placed along the edge of the shower, perfect for walk-in showers. It offers a high-end aesthetic and allows for seamless, uniform tiling.

Wall drain

Integrated into the base of the wall, very modern, it completely frees up floor space and makes cleaning easier.

Drain with non-return valve

Essential in basements or areas prone to backflow. This system effectively protects your bathroom from flooding.

Steps to a professional installation

Evaluation of the existing system: pipe compatibility, slope, soil type
Choice of drain type based on design and required flow rate
Floor preparation: creation of the slope, waterproofing membrane, embedding the drain
System installation and evacuation test
Laying the floor covering (tiles, porcelain, stone, etc.) with finishing around the drain

We ensure perfect alignment and discreet integration, in compliance with the standards of the Quebec Building Code.
