Basement Bathroom Addition – SE Calgary

Adding a below-grade bathroom to an unfinished secondary suite — drainage planning, inspection compliance, and moisture control from the ground up.

Renovated basement bathroom in SE Calgary

Project Overview

This basement renovation involved adding a new bathroom to support a secondary living space in SE Calgary. Below-grade plumbing required inspection compliance and careful slope planning.

The basement was entirely unfinished at the start of the project. No prior bathroom existed in this area — every element was installed from scratch.

Key Considerations

Below-grade work presents unique challenges compared to main-floor bathrooms. The unfinished starting point required planning for:

  • Concrete slab cutting required
  • Drain location planning
  • Backwater protection needed
  • Moisture control strategy

Scope of Work

Concrete cutting and trenching
Installation of below-grade drain system
Backwater valve integration
Moisture-resistant backer systems
Porcelain tile flooring
Compact vanity installation
Inspection coordination

Drainage planning followed municipal code requirements.

Outcome

The completed bathroom passed inspection and supports long-term durability. Proper drainage planning reduces flood risk and moisture buildup.

This project demonstrates that basement bathroom additions require significantly more planning than above-grade work — but done correctly, they add lasting value to secondary suites.
