What Determines a Bathroom Renovation's Real Cost
Two bathrooms that look identical in size can cost very differently to renovate once you account for what's behind the walls and under the floor.
Existing Plumbing Layout
Moving a toilet or shower drain even a few feet can mean cutting into a concrete slab or rerouting a stack, which is a materially different job than reusing existing rough-in locations. We confirm your layout goals against your existing plumbing before pricing.
Waterproofing Membrane Systems
A shower that will hold up needs a proper waterproofing membrane behind the tile, not just tile adhesive on drywall. This is one of the most commonly skipped items in low-ball bathroom quotes, and it's the one most likely to cause a subfloor problem within a few years.
Exhaust Ventilation Sizing
Ontario's humid summers and cold winters both put stress on poorly ventilated bathrooms, leading to mould behind trim and peeling paint. Exhaust fan sizing needs to match the room's volume, not just be whatever unit was on the shelf.
Older Home Plumbing Materials
Homes with original galvanized or cast iron plumbing often need portions replaced during a bathroom gut, which is a cost factor a quick phone-quote can't account for.
Low Quotes Often Skip the Membrane, Not the Tile
Tile is visible, so it's rarely where corners get cut. Waterproofing membrane is invisible once the tile goes up, which makes it an easy line item to quietly drop from a low quote. The homeowner doesn't find out until grout starts failing or a stain appears on the ceiling below.
We Itemize Waterproofing Separately From Finishes
Our bathroom quotes list membrane systems, shower pan work, and ventilation as their own line items, separate from tile and fixtures. That way you can see exactly what's being spent on the parts of the job that protect your subfloor and the room below, and you're not trusting that it was 'included' somewhere.

Bathroom Renovation Questions
Can you move my shower or toilet to a different spot?
Often yes, but the cost depends heavily on your existing plumbing layout and whether it involves cutting into a slab. We confirm this before quoting.
Why does waterproofing cost extra if it's supposed to be standard?
It should be standard, which is exactly why we list it as its own line — so you can see it's genuinely included rather than assumed.
Do older homes need extra plumbing work during a bathroom reno?
Sometimes. Homes with original galvanized or cast iron lines may need sections replaced, which we flag during our initial review.
How long does a full bathroom renovation take?
It depends on scope and whether plumbing is being relocated. We give a project-specific timeline in your quote.
Do you handle the permit for plumbing changes?
Yes, where a permit is required for the plumbing or electrical work involved, we handle the application and scheduling.
