Renovating a Century-Old Bathroom in Ottawa: Challenges & Rewards

Ottawa’s older neighbourhoods are full of history, character, and charm. Owning a house in these areas is a point of pride. Places like the Glebe, Sandy Hill, Centretown, and Old Ottawa South are filled with homes built more than 100 years ago. 

Old Ottawa bathroom renovations in a century-old home, charm often meet reality. Behind the walls and under the floors are unique challenges that require expertise, patience, and a clear plan. 

Common Challenges in Century-Old Bathrooms

As charming as older houses are, they come with a whole host of construction challenges. Here’s the list of issues we have to tackle when managing bathroom renovation in Ottawa’s older areas. 

Outdated Plumbing

Many homes built before the mid-20th century still rely on galvanized steel or cast-iron pipes. These materials corrode over time, reducing water flow. Replacing them with modern copper or PEX piping is essential for reliability and efficiency.

Electrical Safety

Older bathrooms were never designed to handle today’s electrical loads. Hair dryers, heated floors, or even LED lighting can overwhelm outdated wiring. Rewiring to the current code, adding GFCI outlets, and ensuring proper grounding are non-negotiable upgrades.

Space Constraints

Bathrooms in the Glebe or Centretown were often compact. Maximizing storage and improving layout are challenges. Creative solutions, such as floating vanities, pocket doors, and custom-built shelving, help make the most of limited space.

Uneven Floors and Walls

After a century, it’s common to find sagging floors, cracked plaster, or uneven tile substrates. These issues must be addressed before new finishes are installed. Levelling floors and reinforcing joists protect your investment and ensure a quality renovation.

Hidden Surprises

Opening up walls in a Sandy Hill Victorian can reveal anything from knob-and-tube wiring to old lead pipes. Budgeting for contingencies is critical. Many contractors recommend setting aside 15–20% of your budget for unexpected discoveries.

The Rewards of Restoring and Renovating

Preserving Character

Century-old homes often feature high ceilings, large windows, and architectural details that are worth preserving. By blending period-appropriate finishes—like clawfoot tubs, mosaic tile, or vintage-inspired fixtures—with modern functionality, you keep the home’s personality intact.

Increasing Home Value

Updated bathrooms are one of the strongest investments. According to the Canadian Real Estate Association, bathroom renovations can yield up to 75% of their cost in added home value. In sought-after neighbourhoods like the Glebe or Sandy Hill, this return can be even higher.

Modern Comforts

Heated floors, walk-in showers, and efficient fixtures provide comfort that century-old bathrooms lacked. Combining modern amenities with historical design elements gives you the best of both worlds.

Energy and Water Savings

Upgrading to low-flow toilets, efficient faucets, and LED lighting reduces your utility bills. It also lowers your environmental impact, which matters in a city focused on sustainability like Ottawa.

Practical Steps to Renovating a Century-Old Bathroom

  1. Start with a Professional Assessment

    Hire experts to inspect plumbing, electrical systems, and structural integrity. This sets the foundation for a realistic plan.
  2. Set a Realistic Budget

    Renovating a century-old bathroom is not the same as updating a suburban en-suite. Expect higher costs for demolition, disposal, and specialized trades.
  3. Plan for Permits

    Ottawa’s older neighbourhoods often have heritage overlays. Depending on the scope, you may need city permits or approvals to preserve certain features.
  4. Choose the Right Contractor

    Experience matters. Contractors familiar with older homes understand how to address uneven framing, heritage finishes, and tricky layouts. Miracle Dream Homes, serving Ottawa since 2004, specializes in bathroom renovation projects that respect both history and functionality.
  5. Blend Old with New

    Consider refinishing an antique vanity with a modern sink, or pairing subway tile with original wood trim. These design choices preserve the authenticity of your bathroom while ensuring it meets today’s standards.

One homeowner in the old Ottawa South wanted to restore a bathroom in their century-old brick house. The bathroom had its original clawfoot tub but suffered from leaking plumbing and drafty windows. Check this link for more information about this bathroom renovation project.

Our team carefully modernized the space while preserving its historical charm, installing a new vanity, an efficient toilet, and a custom-tiled shower that blended seamlessly with the home’s timeless aesthetic. We reinforced old structures and worked around original features to ensure both safety and style.

The final result is a beautifully updated bathroom that respects the home’s history while offering modern comfort.

Other work on the project included: 

  • Replacing corroded cast-iron and copper pipes with PEX
  • Installing heated tile floors for comfort
  • Adding a custom vanity with a quartz countertop
  • Upgrading electrical wiring to the current code

The result was a bathroom that maintained its early 20th-century charm while functioning as a modern, comfortable space.
