What We Build

A bathroom renovation can range from a refresh of fixtures and finishes within an existing footprint, to a complete gut with new layout and updated plumbing, to a master ensuite expansion involving structural work and wall relocations. ScaleBig handles the full range, with one accountable team from design to handover.

Every project is designed in house before construction begins: layout, tile, vanity, fixtures and photorealistic 3D renderings. A dedicated project manager runs your job from start to handover, with one point of contact throughout. The same vetted trades work on every project. Plumbing, electrical, waterproofing, tile and finishing are coordinated as one continuous process.

A well built bathroom is mostly invisible. The waterproofing membrane, the slope of the shower pan, the drain placement, the plumbing and the ventilation. None of it shows when the project is finished. These details support drainage, moisture control and lasting performance, even when they are hidden by the finished surfaces.

Your Renovation, Professionally Scoped

Our packages illustrate different renovation experiences and representative project scopes. Every property is unique, so your final quotation is tailored to your layout, existing conditions, selected finishes and construction requirements.

We'll help you choose the right direction and develop a complete project scope around your goals.

Our Project Timeline Commitment

We believe homeowners deserve clarity about when their renovation will be completed.

Before construction begins, we'll provide an agreed project schedule with a target completion date. We'll keep you informed of progress, communicate clearly and manage the work toward the agreed timeline.

Initial consultations and estimates are free. Separately contracted design, engineering, permit applications or advanced assessments are not automatically free and may require an additional agreement.

Our Approach

Waterproofing, drainage and ventilation deserve careful planning in every bathroom renovation. A correctly specified waterproofing system helps protect the wall assembly. The shower base and drain must work together to move water away, and properly sized ventilation helps manage moisture. We treat the work that sits behind the tile as the most important part of the project.

Design starts with our in house designer. Layouts, tile selections, vanity and fixture specification, lighting strategy, and photorealistic renderings are developed before construction begins. The homeowner sees the finished bathroom in detail and makes material decisions with full visibility.

On site, one project manager runs your job and is your single point of contact. The plumbers, electricians, tilers, and finishers on your project are the same trades on every ScaleBig project, working to a known standard. Inspections are coordinated where required, and any structural work is built from engineered drawings.

Dedicated circuits, GFCI protection, fan venting routes, switch placement, and any panel upgrades required to support the new electrical load.

08

Waterproofing Membrane

Schluter or comparable waterproofing system applied to all wet walls, the shower pan, and any surfaces with direct water exposure, installed before tile work begins.

09

Shower Pan & Drainage

Pre sloped shower pan or wet room build up with linear or point drain placement, sloped to drain correctly without pooling.

Selections and Purchasing

You approve the finishes. We coordinate ordering and delivery, with material availability and lead times considered before construction starts.

Our in house designer prepares a selection sheet with every tile, fixture, vanity and light, priced within the allowances in your proposal. You sign off on each item.

Selections are locked by a date in your schedule. Late changes move the schedule and are priced in writing.

Anything above an allowance is quoted in writing before we order it. You never see a surprise on the final invoice.

After you sign, you approve your final selections and pay for finish materials, so everything is ordered and on site before demolition starts.

What Determines the Cost

Bathroom renovations at ScaleBig typically range from $20,000 to $60,000 or more. The number depends much less on bathroom size than on the scope of the work, the complexity of the layout changes, and the finish level selected. The factors below are what move the budget within and beyond that range.

01

Scope of the Project

A refresh project (new fixtures, vanity, and finishes within the existing footprint and plumbing locations) is meaningfully different from a gut renovation with new layout, relocated plumbing, and a different shower configuration. Scope is the primary cost driver.

02

Plumbing Relocations

Moving the toilet, shower, or vanity to a new location involves substantial plumbing work, and in upper floor bathrooms, often involves opening the ceiling below. The cost of relocation is real and worth weighing carefully during design.

03

Shower Type

A standard tub and shower combination, a glass enclosed shower with a tiled pan, a curbless walk in, and a full wet room are all different builds with substantially different costs. Curbless and wet room construction in particular require more structural preparation.

04

Tile Selection and Coverage

Tile pricing varies widely, from basic porcelain to large format slabs, specialty patterns and natural stone. Coverage matters too: a fully tiled shower with a tile niche, tile bench, and floor to ceiling walls represents far more material and labour than a basic surround.

05

Vanity and Storage

Stock vanity versus semi custom versus fully custom millwork significantly changes the budget. Built in storage, linen towers, and integrated medicine cabinets all add scope.

06

Fixtures and Hardware

Faucets, shower systems, tub fillers and hardware can vary by thousands of dollars. Designer brands, thermostatic valves and multi function shower systems sit at the higher end.

07

Structural Work

Wall removals or relocations, knee wall changes for vaulted ceilings, or any structural modifications add real cost and require engineered drawings.

08

Permits and Inspections

Most bathroom projects do not require permits. Structural work, new plumbing locations, electrical panel upgrades, or window relocations may trigger permit requirements, and we handle the process when they apply.

A specific budget for your project is developed during the site assessment, after we've reviewed the conditions and discussed the scope you're looking for.

The Process

Every bathroom project at ScaleBig follows the same sequence. These are typical timelines. Your proposal sets out the milestones and schedule for your project.

  1. 01

    Free Consultation

    We discuss your project, review the preliminary scope and budget, and arrange an initial site visit where appropriate, to measure and check what is behind the walls where needed. The initial consultation and estimate are free.

  2. 02

    Design & Renderings

    Our in house designer develops the layout, selects tile and fixtures, specifies vanity and storage, and produces photorealistic 3D renderings. All material decisions are made before construction begins.

  3. 03

    Drawings & Permits Where Required

    Architectural drawings, engineered drawings for any structural work, and permit applications when applicable.

  4. 04

    Proposal & Agreement

    A fixed price proposal with the scope set out by category, your allowances for finishes, milestones, the payment schedule and exclusions. Once signed, your project is scheduled with dates.

  5. 05

    Selections Locked

    You approve the final selection sheet and pay for finish materials. We order everything so it is on site before demolition starts.

  6. 06

    Construction

    Demolition, structural work, plumbing and electrical rough ins, waterproofing, tile, fixtures and finishing, sequenced properly with cure times between phases.

  7. 07

    Final Walkthrough & Handover

    Punch list, fixture commissioning, and handover of warranties and any permit documentation.

Typical timelines: 2 to 4 weeks for design and any required permits, then 4 to 8 weeks of active construction depending on scope.

Where We Don't Compromise

Some elements of a bathroom renovation are easy to cut corners on. These are the ones that cause the most damage when done poorly.

01

Waterproofing Membrane

We use Schluter or comparable approved systems on all wet walls and shower pans. The membrane is installed in full, with proper overlap and corner detailing, before tile work begins. This is not a step we shortcut, ever.

02

Shower Pan Slope

The shower pan is sloped properly toward the drain, typically a quarter inch per foot, built up before tile installation, not corrected with thinset during tile setting. Water has to go where it's supposed to go, every time.

03

Substrate Preparation

Concrete board, cement based underlayments, and any wood substrate transitions are prepared to manufacturer specifications, including fastener spacing, seam treatment and primer where required. Tile sets are only as good as what's underneath them.

04

Ventilation

Bathroom exhaust fans are sized correctly for the bathroom volume and vented to the exterior of the home, never into the attic. Improper venting is one of the leading causes of hidden moisture damage in bathrooms.

05

Plumbing Behind the Walls

All new plumbing is run with appropriate materials, proper slope on drains, and code compliant fitting techniques. Shut off valves are placed accessibly, not buried behind tile.

What Sits Behind the Tile

Tile, vanity, fixtures and paint are what homeowners see, and what most contractors talk about. The work that determines whether a bathroom lasts is mostly invisible. The list below is what we treat as essential on every bathroom project, regardless of the visible finish level.

01

Waterproofing System

A complete Schluter or comparable waterproofing membrane on all wet walls and the shower pan, with full corner and seam detailing. This is the actual water barrier. Tile and grout are not waterproof on their own.

02

Pre Sloped Pan or Mud Bed

The shower pan is built up to a proper slope toward the drain before tile installation. Slope is created in the underlayment, not in the tile setting bed.

03

Drain Selection and Placement

Linear drains, point drains, and curbless drainage systems are selected to match the design intent and installed in the correct location relative to slope and water flow.

04

Backer Board Installation

Concrete or cement based backer board is installed on all wet walls using the correct fasteners at correct spacing, with seams taped and treated per manufacturer specifications.

05

Plumbing Behind the Walls

New supply and drain lines installed with appropriate materials, correct slope on drains, accessible shut off valves, and proper sequencing of fittings.

06

Insulation and Vapour Management

Exterior walls in the bathroom are properly insulated and vapour managed. This prevents cold side condensation that can otherwise build up inside the wall cavity.

07

Ventilation Routing

Exhaust fan routing is run through the attic or wall cavity to an exterior wall or roof cap, never terminated in the attic space. Duct size matches fan CFM specifications.

08

Electrical Behind the Walls

GFCI protected circuits, dedicated circuits where required, appropriately sized wire for the fixture load, and any junction boxes accessible.

Accessible and Curbless Showers

For a parent who should not be stepping over a tub wall, or anyone planning to stay in their home for good. We build curbless walk in showers with the floor recessed to slope to the drain, solid blocking behind the walls for grab bars, a built in bench, a handheld shower on a slide bar, and slip resistant floor tile. If an occupational therapist has assessed the home, we build to their recommendations. It still looks like a beautiful bathroom, not a hospital room.

Frequently Asked Questions

Most bathrooms take 4 to 8 weeks of construction, after 2 to 4 weeks of design and any permits. You receive a dated schedule when you sign, and a written update every Friday.

When plumbing moves, walls change or structure is involved, a permit is usually required. We confirm this at the site assessment and handle the application and inspections.

Yes, in most cases, as long as there is another working bathroom. We protect the floors and clean the site every day.

Tile and grout are not waterproof. A bonded waterproofing membrane behind the tile is what keeps water out of your walls and floor. Every shower we build has one.

Usually, yes. It means recessing or sloping the floor so water reaches the drain with no curb. We check your floor structure at the assessment.

Yes. You approve every selection on a signed selection sheet, and we purchase, track and deliver everything.

Yes. If a wall is load bearing, we work from stamped drawings by a licensed engineer and handle the permit.
