Most homeowners don’t replace their bathtub because it’s broken – they replace it because they no longer use it.
With 20 years of experience renovating bathrooms, I’ve helped homeowners make that switch with clear expectations and no surprises. In this article, I’ll explain what a tub-to-shower conversion includes, how it works, and what it typically costs in Ottawa.
The short answer
A professional tub-to-shower conversion in Ottawa typically runs $13,000 to $15,000, with most projects starting near the $13,000 mark. Where a project lands in that range is driven by product selections and by what is found behind the existing wall, not by the size of the room alone.
- A standard conversion covers removal of the old tub, the wall system, shower base, valve and fixtures, waterproofing and finishing.
- It does not automatically cover moving drain or supply lines, structural or moisture repair behind the wall, or premium glass and panel upgrades.
- Bytown installs modern walk-in showers in 1 to 3 days on a straightforward scope.
- Moving plumbing or altering walls can trigger a City of Ottawa building permit.
Tub-to-Shower Conversion: What’s Included
A tub-to-shower conversion is more than simply removing a bathtub and sliding a shower base into its place. At its core, it’s a full reconfiguration of how water, walls, and daily use come together in your bathroom.
In most homes, bathtubs were installed decades ago using materials and waterproofing methods that no longer meet modern standards. Converting to a shower allows you to upgrade not only the visible finishes, but also what’s behind the walls, creating a cleaner, safer, and more functional space that fits how you actually live today.
Bytown Bath’s Tub-to-Shower Conversion Process
Every tub-to-shower conversion we complete follows a structured process designed to eliminate guesswork and protect your home. From consultation to installation, each step is carefully planned to ensure finishes and behind-the-wall details are handled properly.
Step 1: In-Home Consultation

Every project starts with an in-home consultation and a detailed estimate. During this visit, we assess the existing bathroom layout, review plumbing locations, and discuss how the space is currently used. That scope review also tells us whether the job needs a City of Ottawa building permit, since moving drain lines or altering walls changes what is required. We also guide you through selecting all major components, including wall systems, shower bases, doors, and fixtures, so there is a clear plan before any work begins.
From start to finish, you are choosing everything top to bottom, with no surprises later on.
Step 2: Demolition and Preparation

Once selections are finalized, demolition begins. The existing bathtub and surrounding wall finishes are fully removed, and in most cases, the renovation is taken back to the studs. This step allows us to inspect the framing, plumbing, and waterproofing behind the walls and address any issues that are not visible on the surface.
Proper structural preparation is critical. By starting with a clean slate, we can rebuild the shower area correctly and ensure the new system is designed to last, not just look good on day one.
Step 3: Installation and Finishing

After preparation is complete, we install the new shower base, wall system, updated plumbing fixtures, and any built-in storage features such as recessed niches. Each component is installed with attention to alignment, waterproofing, and long-term durability.
The project concludes with finishing details and a thorough cleanup. Most tub-to-shower conversions are completed within three to five days, depending on the condition of the existing bathroom and what is discovered once the walls are opened.
Tub-to-Shower Conversion Cost in Ottawa
In Ottawa, a professional tub-to-shower conversion typically ranges from $13,000 to $15,000, with most projects starting around the $13,000 mark. Where a project lands in that range depends largely on product selections and the condition of the existing bathroom.
| Part of the job | In a standard conversion | Priced separately when it applies |
|---|---|---|
| Old bathtub and surround | Removed and disposed of; area taken back to the studs in most homes | Disposal of unexpected material found behind the wall |
| Behind the wall | Framing, plumbing and waterproofing inspected before rebuild | Repair of water damage, mould or rotted framing found on opening |
| Shower base | New base sized to the existing tub footprint | Low-threshold or barrier-free base where accessibility is the goal |
| Wall system | New wall system installed and sealed | Premium panel or tile selections above the standard allowance |
| Plumbing | New valve and fixtures in the existing locations | Moving the drain, supply or vent, which can also trigger a permit review |
| Enclosure | Door or enclosure to the agreed specification | Frameless or custom glass upgrades |
| Storage | Built-in features such as recessed niches where specified | Additional built-ins added after the scope is written |
Factors That Affect the Final Cost
- Product choices: Premium panels, glass doors, and upgraded fixtures increase cost.
- Existing conditions: Repairs may be required in older bathrooms.
- Accessibility needs: Low-threshold bases and safety features affect pricing.
- Layout changes: Plumbing or wall changes add labour and materials.
What Homeowners Wish They Knew Before
A clear scope of work is the difference between a smooth renovation and an expensive surprise. Many older tub surrounds appear fine on the surface but lack proper waterproofing behind the walls. As Curtis McGrath, Owner of Bytown Better Bathtubs & Showers, often points out, “An older wall system may look okay on the outside, but once we open it up, we sometimes find water damage or mould that needs to be treated.” That’s why detailed estimates matter.
At Bytown Bath, what’s included and what’s not is clearly documented before work begins, so there is no confusion once the project is underway. You should expect transparency, not vague allowances or assumptions, when reviewing any tub-to-shower conversion quote.

Tub-to-shower conversion: questions Ottawa homeowners ask
How much does a tub-to-shower conversion cost in Ottawa?
A professional tub-to-shower conversion in Ottawa typically runs $13,000 to $15,000, with most projects starting around the $13,000 mark. Where a project lands in that range depends on product selections and on the condition of the bathroom behind the existing wall.
How long does a tub-to-shower conversion take?
Bytown installs modern walk-in showers in 1 to 3 days on a straightforward scope. Repairs discovered once the wall is opened, or a special-order selection with a supplier lead time, can extend that.
Do I need a permit for a tub-to-shower conversion in Ottawa?
It depends on the scope. A conversion that keeps the same footprint and the same drain and supply locations usually does not raise the question. Moving the drain, supply or vent, or altering walls or structure, can require a building permit. Confirm your specific case with City of Ottawa Building Code Services before work begins.
What is included in a tub-to-shower conversion?
A standard conversion covers removal and disposal of the old tub and surround, inspection of the framing and waterproofing behind the wall, a new shower base sized to the existing footprint, a new wall system, a new valve and fixtures in the existing locations, the enclosure, and finishing. Structural or moisture repair found on opening, moved plumbing and premium upgrades are priced separately.
Why is one quote $1,200 and another $13,000?
Because they are different products. A quote near $1,000 is a tub cut-out — a section of the existing tub is removed so you can step through, and everything else stays. The $13,000 to $15,000 figure on this page is a full conversion, rebuilt from the studs with new waterproofing. We compare the two honestly in our guide to the cheapest ways to convert a tub.
Is a tub-to-shower conversion worth it?
It is worth it when the tub is no longer used, when stepping over the tub wall has become a daily problem, or when the wall system behind the finishes has reached the end of its life. It is not the right answer for a purely cosmetic refresh, which is a different and much smaller job.
Stop Stepping, Start Showering
Atub-to-shower conversion is a practical upgrade to how your bathroom functions day to day. When planned properly, it enhances safety, updates the space, and adds lasting value without the scope of a full remodel.
