Tub-to-Shower Conversion in Ontario

Most bathtubs in Ontario get used as shower floors. If nobody's had an actual bath in yours since the kids grew up, that tub is sixty gallons of wasted space with a high, slippery wall you climb over twice a day. Converting it to a walk-in shower is one of the most requested bathroom jobs going, and one of the most satisfying.

The conversion uses the tub's existing footprint and drain zone, which keeps the plumbing changes contained — the drain moves within the old tub's area and the valve gets replaced while the wall is open. From there it's a normal shower build: waterproofed walls, a low-threshold base or fully tiled floor, and glass or a curtain depending on taste and budget.

It's also the classic aging-in-place move. A low or zero threshold, a built-in bench, blocking in the walls for grab bars — decisions that cost little during the build and matter enormously later. One honest note: if it's the only tub in the house, some buyers expect at least one bathtub, so think about which bathroom gets the conversion.

What this covers

  • Tub removal and disposal
  • Drain relocation within the old tub footprint and new valve installation by licensed plumbers
  • Waterproofed wall rebuild in the wet zone
  • Low-threshold acrylic bases or fully tiled shower floors
  • Wall tile or wall-panel systems
  • Glass panels, doors, or curtain-rod finishes
  • Benches, niches and grab-bar blocking on request
  • Repair of any hidden damage found under the old tub
  • Grout, silicone and cleanup

What affects the price

  • Tiled shower floor versus low-threshold base
  • Wall finish — tile versus panel systems
  • The condition under the old tub: decades of slow seepage sometimes leave repairs
  • Valve and plumbing scope inside the wall
  • Glass choice, from curtain to frameless panel
  • Accessibility details — zero-threshold entries take extra floor work
  • Whether the rest of the bathroom is being refreshed at the same time

Common questions

How long does a tub-to-shower conversion take?
Typically three days to a week: tub out and plumbing roughed in early, then waterproofing, walls, base or floor tile, and finally silicone that wants a day to cure before first use. A panel-system conversion lands at the fast end; a fully tiled floor at the slower end.
Will removing the tub hurt my home's resale value?
The usual guidance is to keep at least one tub in the house for families with small kids — if you have a second bathroom with a tub, convert freely. If it's the only tub, weigh how long you plan to stay. For most people staying put, the daily convenience wins.
Can the shower have no lip at all to step over?
A zero-threshold (curbless) entry is doable — it needs the floor rebuilt so the slope carries water to the drain, which is more work than a low-curb base but the result is curbless and wheelchair-friendly. A low 3–4 inch threshold gets most of the benefit at less cost.
Do you reuse the tub's plumbing?
The supply lines and drain location get reused as the starting point, but the tub spout goes away, the valve is replaced with a proper shower valve, and the drain typically shifts to the new shower's centre — licensed plumbing work while the wall and floor are open anyway.
What happens if there's rot under the old tub?
It gets photographed, priced and fixed before the new shower goes in — building over soft subfloor is how the last shower ended up leaking. Old tubs hide sins; finding them mid-job is normal and fixing them then is the cheapest it will ever be.
