The shower and floor drain

Why is the choice of drain so important?

The drain is responsible for removing water from the plumbing system. If it is improperly installed, sized, or positioned, 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.

When should you replace or install a new drain?

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.
