Tub-to-Shower Conversions Done by Licensed Sarnia Contractors

Most Sarnia homes built before 1990 have one thing in common: a tub-and-shower combo in a five-foot alcove. It works, but stepping over that tub wall gets old fast. It's also the most common place in the house for a slip.

A tub-to-shower conversion pulls out the tub and puts a walk-in shower in the same spot. Because the drain and water lines are already there, it's one of the best-priced upgrades you can make to a bathroom. Most conversions take three to seven working days.

What's Included in a Walk-In Shower Conversion

Every job is different, but a full tub-to-shower conversion usually covers:

Tear-Out and Disposal

Your contractor removes the old tub, surround, tile and drywall, and hauls it all away. Older cast-iron tubs are heavy, so this step alone is worth hiring out.

Plumbing Updates

The drain moves from the end of the tub to the right spot for a shower pan. Your contractor can also swap old valves for a pressure-balanced valve, so the water doesn't turn scalding when someone flushes.

Waterproofing

This is the step you never see and the one that matters most. A good contractor uses a full waterproofing system behind the tile, not just green drywall. Skipping it is how showers rot out in five years.

Shower Base and Walls

You choose a tiled floor or a factory-made shower base, and tile or solid panels for the walls. More on that below.

Glass, Fixtures and Finishing

A glass door or fixed panel, a new shower head, a handheld wand if you want one, niches for shampoo, and a clean finish on the trim and paint.

Walk-In Shower Options

Low Curb or No Curb

A low-curb shower has a small lip, usually 2 to 4 inches, to keep water in. A curbless shower has no lip at all, so you can walk or roll straight in. Curbless takes more work because the floor has to slope to the drain, but it's the best choice if you're planning to stay in your home as you age. Accessible bathroom options

Tiled Shower or Panel Walls

Tile gives you the most choice in colour, size and style. Large-format tile means fewer grout lines to clean. Solid panels (acrylic, solid-surface or stone-look composite) go up faster and have no grout at all. Both last for decades when installed well.

Door or Open Entry

A hinged or sliding glass door keeps the most water in. A fixed glass panel with an open end looks clean and is easy to get in and out of, but needs a bit more room.

Extras Worth Asking About

A recessed niche for bottles
A built-in or fold-down bench
Grab bars (have your contractor add wood backing in the walls now, even if you add the bars later)
A handheld shower on a slide bar
A linear drain for a sleek, curbless look

Custom Tile vs. One-Day Acrylic Liners

You've probably seen ads for showers installed in a day. Those systems slide acrylic walls over or in place of your old tub surround. They're fast and they're fine for some homes.

A full conversion is different. Your contractor takes everything down to the studs, checks for rot and old plumbing, waterproofs properly, then builds the shower you want in any size or style. It costs a little more and takes a few more days. You get a custom shower, and you know what's behind the walls.

Tub-to-Shower Conversion FAQs

How long does a tub-to-shower conversion take?

Most tub-to-shower conversions take three to seven working days from tear-out to final clean. Panel showers are quicker. Fully tiled showers take longer because the waterproofing, thinset and grout need time to cure. If your contractor finds rot or old plumbing, add a day or two.

Will removing my only bathtub hurt my home's resale price?

It can, if you have young kids or you're selling to families. Real estate agents often suggest keeping at least one tub in the house. If this is your only bathroom and you plan to sell soon, ask your contractor about keeping a tub. If you're staying put, a safe shower may be the smarter choice.

Can you convert a tub to a shower in a small bathroom?

Yes. Most conversions happen in a standard five-foot tub alcove, which is a great size for a walk-in shower. A contractor can also fit a corner shower or a 36-inch square shower in a tight room. Clear glass and large tile help a small bathroom feel bigger.

How much does a walk-in shower cost in Sarnia?

A walk-in shower conversion in Sarnia usually costs $6,000 to $15,000 in 2026. Panel showers with a factory base sit at the low end. Custom tiled and curbless showers sit at the high end. You'll get an exact price in a written quote after a free visit.
