What Does a Full Bathroom Renovation Include in Toronto?

A full bathroom renovation in Toronto means stripping the space back to studs and subfloor, addressing everything behind the walls — waterproofing, plumbing rough-in, electrical — and rebuilding it completely with your chosen materials and layout.

At GoGajic, a full bathroom renovation scope typically includes:

  • Full demolition to studs and subfloor
  • Plumbing rough-in: drain relocation, supply line upgrades, fixture rough-in
  • Electrical rough-in: GFCI outlets, exhaust fan, pot lights, in-floor heat wiring
  • Cement board substrate and full waterproofing system (Schluter or equivalent)
  • Custom tile installation: floor, shower walls, feature walls, niches, benches
  • Custom shower build: curbless, curbed, or tub-shower combo
  • Vanity supply and installation (freestanding, floating, or built-in)
  • Countertop and sink installation
  • Toilet supply and installation
  • Shower glass supply and installation (frameless, semi-frameless, or panel)
  • Accessories: towel bars, toilet paper holder, hooks, mirror or medicine cabinet
  • Paint, trim, and final finishes
  • Permit drawings where scope requires (in-house — no third-party delays)

The difference between a GoGajic bathroom and one built by a series of disconnected trades is accountability. Every element — from the waterproofing membrane to the final caulk bead — is our responsibility.

Bathrooms are the most technically demanding room in a house per square foot. Waterproofing done wrong isn't discovered for 3–5 years — by which point you're looking at mould remediation and a full redo. We do waterproofing the way it should be done, the first time, and we back it with a 5-year warranty.

Types of Bathroom Renovations We Build Across Toronto & the GTA

Primary Ensuite Renovation

The most requested bathroom project for Toronto homeowners. A primary ensuite renovation transforms the master bathroom into a spa-calibre space — curbless walk-in shower, freestanding tub, double vanity, heated floors, and premium tile throughout.

What’s typically involved:

  • Full gut to studs
  • Layout reconfiguration (moving plumbing where needed)
  • Curbless walk-in shower with linear drain
  • Freestanding soaker tub installation
  • Double floating or built-in vanity
  • In-floor radiant heat (electric mat system)
  • Large-format tile floors and walls (24×48, 32×32, or herringbone)
  • Frameless glass shower enclosure
  • Pot lights and backlit mirror 

Main Bathroom Renovation

Toronto’s main bathrooms — shared by the whole household — often need to work harder than any other room in the house. GoGajic reconfigures, rebuilds, and optimizes main bathrooms for durability, function, and a finish that holds up to daily use.

Common scopes:

  • Full gut and rebuild in existing footprint
  • Tub-to-shower conversion (or tub replacement)
  • New tile floor and tub/shower surround
  • Vanity and toilet replacement
  • Updated exhaust, lighting, and outlets

Powder Room Renovation

High-visibility, low-square-footage — powder rooms are one of the fastest renovation ROI opportunities in a Toronto home. GoGajic powder room renovations focus on statement finishes: bold tile, designer fixtures, floating vanities, and custom mirrors.

Common scopes:

  • Full tile floor and feature wall
  • Floating or pedestal vanity with vessel or undermount sink
  • Toilet replacement
  • Designer faucet and accessories
  • Statement mirror or backlit mirror
  • Pot light or sconce lighting 

Tub-to-Shower Conversion

One of the most practical bathroom renovations for Toronto families: removing an underused bathtub to create a larger, fully tiled walk-in shower. GoGajic handles the full conversion — drain relocation, waterproofing, tile, and glass — as a single coordinated scope.

What’s involved:

  • Tub removal and subfloor repair
  • Drain relocation (where required)
  • New shower pan: mud bed, linear drain, or prefab base
  • Full waterproofing system
  • Custom tile walls and floor
  • Niche, bench, and shelf integration
  • Frameless or semi-frameless glass 

Accessible & Walk-In Shower Renovations

GoGajic designs and builds accessible bathroom modifications for aging-in-place clients — curbless shower entries, grab bar blocking, comfort-height toilets, wider door openings, and non-slip tile selections. These projects are designed to be both functional and beautiful, not clinical. 

Basement Bathroom Addition

Adding a bathroom to an existing basement is one of the highest-ROI scope additions in Toronto real estate. GoGajic handles the complete scope — rough-in plumbing below slab (saw-cut and repour), framing, waterproofing, tile, fixtures, and electrical — as part of a coordinated basement renovation or as a standalone addition.

Bathroom Tile Styles Our Toronto Clients Love

Tile is the single biggest visual decision in a bathroom renovation. Here are the directions GoGajic clients consistently choose:

Large-Format Minimalist

32×32 or 24×48 porcelain slabs in light grey, warm white, or concrete tones. Fewer grout lines, clean aesthetic, easy to maintain. Popular in modern ensuite renovations across Toronto and North York.

Classic White Subway

3×6 or 4×12 white subway tile with contrasting grout — charcoal, black, or warm grey. Timeless, works in both traditional and transitional interiors. High-performing choice for main bathrooms.

Zellige & Handmade Tile

Moroccan zellige or artisan handmade tiles with irregular surfaces and natural variation. Used as feature walls behind freestanding tubs or as full shower surrounds. Creates a bespoke, high-end look that photographs exceptionally well.

Terrazzo & Pattern Tile

Statement floor tile — terrazzo, cement encaustic, or graphic pattern — paired with minimal wall tile. Popular in powder rooms and guest ensuites where the floor is the focal point.

Book-Matched Porcelain Slabs

Continuous vein pattern across large-format panels — mirrors the look of natural marble at a fraction of the cost and with superior durability. Popular for full shower wall cladding in high-end ensuite renovations.

Wood-Look Tile

Porcelain plank tile in wood finishes — warm tones for bathrooms where a natural, organic aesthetic is desired without the moisture sensitivity of real wood flooring.

How Much Does a Bathroom Renovation Cost in Toronto?

Toronto bathroom renovation costs are driven by four factors: room size, scope of plumbing changes, material tier, and whether structural or permit work is required. Here are realistic full-scope investment ranges:

Bathroom Type

Typical Investment Range

Powder room full renovation

$12,000 – $22,000

Small main bathroom (full gut & rebuild)

$22,000 – $40,000

Standard main bathroom (full scope)

$35,000 – $60,000

Primary ensuite renovation

$50,000 – $90,000

Luxury ensuite with freestanding tub + large-format tile

$80,000 – $140,000+

Basement bathroom addition (rough-in below slab)

$25,000 – $50,000

These ranges reflect turnkey, full-scope projects — all trades, materials, and project management included. Supply-only or labour-only scopes are not offered. Material tier (tile selection, vanity, glass, fixtures) is the single biggest variable within each range. 

The most expensive bathroom mistake in Toronto is cutting waterproofing costs. Tile and fixtures can always be upgraded later — a failed waterproofing membrane requires full demolition and a complete redo. GoGajic uses commercial-grade waterproofing systems on every bathroom, regardless of budget tier.

How a GoGajic Bathroom Renovation Works — Step by Step

Same-Week Site Visit & Estimate

We assess your existing bathroom, discuss your goals, identify plumbing and structural requirements, and provide a detailed written estimate within the same week. Clear pricing, expert guidance, and no guesswork or vague ballpark figures.
Step 1

Design & Material Selection

Layout is finalized, tile selected, and fixtures and vanity confirmed. We guide material selections to ensure a cohesive, durable, and budget-friendly design. If permits are required, our in-house drawing team begins preparing permit-ready plans during this phase.
Step 2

Permits (Where Required)

Wall moves, drain relocations, electrical panel upgrades, or basement rough-in additions may trigger a permit requirement. GoGajic prepares drawings in-house and submits to the City of Toronto or your GTA municipality — no third-party engineer delays.
Step 3

Demolition & Rough-In

Full demolition is completed by our in-house team. Plumbing, electrical, and substrate work follows a carefully planned sequence, ensuring every trade is coordinated under one crew. No subcontractor confusion, scheduling conflicts, or delays caused by separate teams working independently.
Step 4

Waterproofing & Substrate

Before a single tile is set, every wet surface is properly waterproofed and inspected. This is the step most contractors rush — and where most bathroom failures originate. We treat it as the most important phase of the build.
Step 5

Tile, Fixtures & Millwork

Tile installation, vanity, countertop, toilet, shower glass, and all accessories are installed in a coordinated sequence by our in-house team. No trades waiting on other trades to show up.
Step 6

Final Finishes & Walk-Through

Paint, trim, caulking, and accessories complete the space. We walk through every detail with you before considering the project done. Your 5-year warranty begins on handover day.
Step 7

Why Toronto Homeowners Choose GoGajic for Bathroom Renovations

Waterproofing Done Right

GoGajic uses commercial-grade waterproofing membranes on every bathroom build — not the industry-standard shortcuts. Proper waterproofing is what separates a bathroom that looks good for 2 years from one that holds up for 20.

All Trades In-House

Plumbing, electrical, tile, glass, millwork — all GoGajic trades. No rotating cast of subcontractors who coordinate by text and show up when they feel like it. One team, one schedule, one point of contact.

5-Year Workmanship Warranty

Every GoGajic bathroom carries a 5-year written workmanship warranty — five times the industry standard. Waterproofing failure, tile delamination, grout cracking due to our work — covered, no debate.

In-House Permit Drawings

When your bathroom project requires a permit, GoGajic handles drawings and submission in-house. No waiting weeks for a third-party engineer to produce a document. Design, permits, and construction move together.

Bathroom Renovation — Frequently Asked Questions

How long does a bathroom renovation take in Toronto?

A full main bathroom gut-and-rebuild typically takes 3–5 weeks from demolition to final handover. A primary ensuite renovation with custom tile and a freestanding tub runs 5–8 weeks. Basement bathroom additions involving rough-in below the slab add 1–2 weeks for concrete work and cure time. We provide project-specific timelines in every written estimate.

Do I need a permit to renovate my bathroom?

Cosmetic renovations — replacing tile, vanity, toilet, and fixtures in their existing locations — typically do not require a permit. You will need a permit if you relocate drains, move plumbing walls, add a new bathroom, or perform electrical panel work. GoGajic confirms permit requirements at the initial site visit and handles all drawings and submissions in-house.

Can you move plumbing to change the bathroom layout?

Yes. Drain relocation — moving the toilet, shower, or tub drain — is one of the most common scopes we handle. On main floor and upper floor bathrooms, this involves opening the ceiling below. For basement bathrooms, it requires saw-cutting the concrete slab. We include this in the full project scope.

What is included in the 5-year warranty?

The warranty covers workmanship — meaning defects caused by our installation, not product manufacturer issues. This includes tile delamination, grout failure, waterproofing leaks, fixture connection failures, and any work-related defect. Manufacturer warranties on products (vanities, fixtures, glass) are governed separately by each manufacturer's terms and are in addition to our workmanship warranty.

What waterproofing system do you use?

GoGajic installs a full waterproofing membrane on all wet surfaces — shower floors, shower walls to the full height of tile, and the area around the tub. We use Schluter Kerdi, RedGard, or equivalent commercial-grade systems depending on the substrate. All junctions and changes of plane receive proper membrane overlap and are inspected before tile installation begins.

Can you do a tub-to-shower conversion?

Yes — it's one of our most frequently requested bathroom scopes. We remove the existing tub, reframe if necessary, relocate or adapt the drain, pour a mortar bed or install a linear drain base, waterproof the full shower pan, and build the custom tiled shower from scratch. The conversion is permitted where required.

Do you install heated floors in bathrooms?

Yes. Electric in-floor radiant heat is one of the most popular add-ons in our bathroom builds — particularly in ensuite renovations. We install the heating mat below the tile and connect a programmable thermostat. The cost to add heated floors during a full renovation is modest compared to retrofitting it later.

Do you work on condo bathroom renovations?

Yes. Condo bathrooms require coordination with building management — approved hours, elevator booking, debris removal protocols, and suite modification approval. GoGajic handles all of this coordination. Note that condo renovations may have restrictions on drain relocation due to shared building infrastructure, which we confirm before scoping.
