Master Ensuite Renovation Ottawa: 2026 Cost & Layout Guide

By Curtis McGrath, Project Coordinator | 18 years renovation experience | Bytown Better Bathtubs and Showers | Updated July 2026

Your ensuite is the one bathroom you use every day, and the one most tied to how the primary bedroom feels. It is also the room where scope varies the most, from a finish refresh to a full gut with a new layout. We renovate ensuites across Ottawa, Kanata, Nepean, Barrhaven, and Orleans, and the first conversation is always the same: how far do you want to take it. For the full pricing picture, our bathroom remodeling cost guide sets out every project size.

What a Master Ensuite Renovation Actually Covers

Scope is the word that decides your budget. At the light end, a refresh keeps every fixture where it is and updates the vanity, tile, lighting, and glass. In the middle, a full gut strips the room to studs but keeps the plumbing in place. At the far end, you move fixtures and sometimes walls to build the room around how you actually use it.

There are three honest approaches. Keep the footprint and replace fixtures in place, which is the fastest and cheapest. Borrow a few feet from an adjacent closet or hallway to gain room for a proper shower or a second sink. Or reconfigure fully, moving plumbing and walls. Each step up adds cost, and the right one depends on what the room is missing, not on what looks best in a showroom.

Layout Choices That Shape the Room

Before tile or fixtures, decide how the room should work each day. These are the choices that make the biggest difference to comfort and to resale.

1. A double vanity, if the room can take it

A double vanity solves the most common complaint couples have about a shared ensuite: the morning collision at a single sink. It is only worth it if the wall is long enough to leave comfortable clearance, since a cramped pair of sinks serves no one. If one person mainly uses the room, a single vanity with more counter and storage often works better.

2. A curbless walk-in shower

More than half of homeowners now prioritise shower size over a tub, and a curbless walk-in shower with a linear drain and a frameless glass panel is the choice that looks current and ages well. A built-in bench and a recessed niche keep the floor clear, and the low threshold makes the room easier to use for years to come.

3. A separate room for the water closet

A separate room for the water closet adds privacy when one person is showering or at the vanity, and it returns well for the space it uses. The trade-off is square footage, so it suits larger ensuites. Where you include one, give it its own exhaust fan, proper clearance, and a door swing that does not crowd the toilet.

4. Tub, freestanding tub, or shower only

A freestanding tub photographs beautifully and gets used rarely. If no one in the house has taken a bath in the last year, that tub is spending some of the best floor space in the room. Keep one tub somewhere in the house for resale, but it does not have to be in the ensuite. Removing an outdated built-in tub often frees room for a wider shower and a larger vanity.

What a Master Ensuite Renovation Costs in Ottawa

Three things move the number: whether you keep or move the plumbing, the size of the room, and the finishes you choose. Here are our approved 2026 prices for the scopes an ensuite usually falls into, before permit.

The entry point is a same-footprint renovation. Moving plumbing to reposition the shower or toilet, and adding premium finishes such as a double vanity, a freestanding tub, or heated floors, is what pushes an ensuite toward the higher end. Our full cost guide lays out the range for every size.

Why Ottawa Families Choose Bytown Bath

We have served Ottawa since 2020 and we renovate bathrooms only. On an ensuite that focus matters, because it sits in your bedroom’s sightline and gets used every day, so the finish and the layout have to hold up to daily life, not just a first look.

Every quote is written and upfront, our installs are handled by professionally trained installers, and we back the product and labour with a written warranty. We tell you plainly what moving plumbing would add before you commit, so the number you get is the number you pay. Payment is 50 percent on booking and 50 percent on completion.

Frequently Asked Questions

How much does a master ensuite renovation cost in Ottawa?

A full renovation fits our complete bathroom renovation scope from $20,000 CAD, or a shower-focused update from $13,000 CAD. Moving plumbing and premium finishes push it higher, and a large ensuite with a double vanity and a separate tub and shower sits well above the entry figure. A precise number needs a walkthrough.

Do I need a permit to renovate an ensuite?

A like-for-like refresh usually does not, but relocating any plumbing fixture such as the toilet, shower, or vanity needs a City of Ottawa plumbing permit, and structural changes need a building permit. We handle the application and the inspections.

Is a double vanity worth it?

Only if the wall is long enough to leave comfortable clearance and two people use the room at once. In a tighter ensuite, a single vanity with more counter and storage, or a larger shower, often serves better than a cramped pair of sinks.

Should I keep the tub in my ensuite?

Many homeowners now prefer a larger walk-in shower to a tub. Keep one tub somewhere in the house for resale, but it does not have to be in the ensuite. A freestanding tub is more of a design feature than a daily one, so choose it for how you will actually use the room.

What adds the most value in an ensuite?

A curbless walk-in shower and a separate room for the water closet tend to return well for the space they use. Timeless, neutral finishes hold their appeal with buyers longer than trend-driven choices that date quickly.
