Ensuite Renovations in Sarnia With Contractors Who Do It Right

Your ensuite is the one bathroom that's just for you. It's where you start and end every day. If yours still has a 1990s corner tub you never use, a single sink you fight over and a shower that's too small, it's time.

An ensuite renovation is usually the biggest bathroom project in a home. It involves more plumbing, more tile and more choices than a main bathroom. That makes the contractor you hire matter even more.

Planning Your Ensuite

Layout

Start with how you use the room. Do you both get ready at the same time? Do you take baths, or only showers? The answers tell your contractor whether to spend space on a double vanity, a bigger shower or a tub. Keeping the toilet and drains where they are saves thousands.

Double Vanity

Two sinks is the most asked-for ensuite upgrade. You need about 60 inches of wall for a double vanity, or 72 inches to be comfortable. A tall linen tower beside it adds storage without eating floor space.

Walk-In Shower

Many homeowners trade the old corner tub for a large walk-in shower with a bench, a niche and a rain head. It uses the space better and it's easier to clean. Walk-in shower options

Freestanding Tub

If you love a bath, a freestanding tub makes the room. It needs clear space around it and a floor or wall-mounted faucet, so plan the plumbing early. Bathtub options

Heated Floors

Electric in-floor heat under tile is one of the best-loved upgrades in a Sarnia winter. It adds about $1,000 to $2,500 to most ensuites.

Lighting and Fans

Layer your lighting: a bright light over the vanity, a wet-rated pot light in the shower and a dimmer for night. A quiet, properly sized exhaust fan vented outside keeps mould away.

Adding an Ensuite to a Bedroom

Plenty of older Sarnia homes have a primary bedroom with no ensuite at all. Adding one is possible in many homes, often by borrowing space from a closet, a small bedroom next door or an over-sized hallway.

The big question is plumbing. Your contractor needs a way to connect the new drains to the main stack and get proper venting. In a bungalow with an open basement, that's usually easy. On a second floor with a finished ceiling below, it takes more work.

Adding a bathroom almost always needs a building permit from the City of Sarnia or your township. A good contractor handles the permit and the inspections for you.

Materials and Finishes

Tile: Large-format porcelain is the go-to for ensuites. It's tough, has fewer grout lines and comes in stone and wood looks.
Counters: Quartz is the most popular choice. It doesn't stain and never needs sealing.
Shower glass: Frameless or low-iron glass keeps the look clean and lets light through.
Fixtures: Brushed nickel, matte black and brushed brass are all in style. Pick one finish and stick with it through the room.
Toilet: A comfort-height or wall-hung toilet makes a big difference day to day.

Ensuite Renovation FAQs

Do I need a permit for an ensuite renovation in Sarnia?

You usually don't need a permit to swap fixtures in the same spots. You usually do need one to add a new bathroom, move drains, add plumbing or take out walls. Rules differ between the City of Sarnia and nearby townships, so your contractor should check and pull the permit for you.

How long does an ensuite renovation take?

Most ensuite renovations take three to five weeks once work starts. Custom glass is often the last piece, since it's measured after the tile is done. Plan on a few extra weeks before that for design and ordering, so materials are on site before tear-out.

Can you add an ensuite to my bedroom?

In many homes, yes. The main question is whether the new drains can reach your main plumbing stack with proper venting. A contractor can look at your home, check the plumbing route and tell you what it would take. Adding a bathroom needs a building permit.

How much does a master bathroom remodel cost in Sarnia?

A master bathroom remodel in Sarnia usually costs $25,000 to $50,000 or more in 2026. Staying in the same layout keeps costs near the low end. Moving plumbing, adding a freestanding tub, heated floors and custom glass push it higher.
