"How much does a bathroom cost?" is the question we hear most, and the honest answer is that it depends on a handful of decisions you make, plus a few things nobody can see until the old walls come down. Two bathrooms the same size can land in very different places. This article walks through what actually moves the number, so you can decide where to spend and where to save before anyone gives you a price.
Scope: refresh, remodel or full rebuild
The single biggest factor is how much you change.
- A refresh keeps the layout and swaps surfaces: new vanity, toilet, lighting, paint, maybe new flooring. The plumbing stays where it is.
- A remodel usually takes the room back to the studs in the wet areas: new tub or shower, new tile, new waterproofing, new fixtures.
- A full rebuild takes everything back to framing and subfloor, often with layout changes, new electrical and new ventilation.
Each step up adds trades, inspection points and days on site. Be clear with yourself early about which one you actually want, because a "small refresh" that quietly grows into a full remodel is where budgets get uncomfortable.
Layout changes and moving plumbing
Keeping the toilet, tub and sink where they are is the most budget-friendly choice you can make. Moving them is absolutely possible, but it means opening floors and walls, rerouting drains with proper slope, relocating vents, and sometimes working around joists that run the wrong way.
Moving a toilet a short distance on a main floor over an open basement ceiling is very different from moving one on a second floor, or on a basement slab where concrete has to be cut. If a new layout would genuinely change how you use the room every day, it is often worth it. If it is a small improvement, it may not be.
Waterproofing systems
This is the part you never see once the tile is up, and it is where we would tell anyone not to cut corners. A tiled shower needs a continuous waterproof layer behind and under the tile. Our standard, in every bathroom at every budget, is cement board with a bonded sheet membrane, using the system's matched drains, corners and seams. We use liquid membrane only for small spot repairs, never as the main waterproofing.
What affects cost here is the size of the wet area, whether you choose a curbless (walk-in) shower, the drain type (a linear drain versus a centre drain), and how many niches, benches and corners need detailing. A curbless shower, for example, often means recessing the floor or building up the rest of the room so water stays where it should. It looks beautiful and is easier to live with as you age, but it takes more work underneath.
Tile size, pattern and material
Tile affects cost in two ways: the material itself and the labour to install it.
- Large-format tile looks clean with fewer grout lines, but it needs a very flat substrate and careful handling. Floors and walls often need extra prep.
- Small tile and mosaics take more time per square metre to set and grout.
- Patterns like herringbone, chevron or a vertical stack with tight alignment take longer and produce more cuts and waste than a simple offset layout.
- Natural stone needs sealing and care, and some stones need specific setting materials.
A good compromise many people like is to put the showpiece tile on one feature wall or the shower floor and keep the rest simple.
Fixtures and finishes
Fixtures range enormously. A thermostatic shower valve with a handheld, rain head and body sprays is a different project than a single pressure-balanced valve. A freestanding tub needs floor-mounted or wall-mounted filler plumbing. Wall-hung toilets and floating vanities need blocking or carriers inside the wall.
Vanities follow the same pattern: a stock unit, a semi-custom unit, or a fully custom piece built by a millwork shop (see our custom millwork page). Counters, mirrors, medicine cabinets, glass shower doors and hardware all add up. None of these are wrong choices; they just need to be chosen early so the price reflects them.
Ventilation
Bathrooms produce a lot of moisture, and in a northern winter that moisture wants to condense on cold surfaces. A properly sized, quiet exhaust fan, ducted to the outside (not into the attic) with an insulated duct, protects the work you just paid for. Upgrading an old noisy fan, adding a humidity-sensing control, or rerouting a duct through a finished ceiling can all affect the cost, and they are worth it.
Heated floors
In-floor heat is one of the most-loved upgrades we see in Edmonton and Prince George bathrooms, because nobody likes stepping onto cold tile in January. Electric mats or cables go under the tile with a dedicated thermostat. The cost depends on the heated area, the controls you choose, and whether a new circuit is needed at the panel.
Surprises behind the walls
Older homes are full of character, and sometimes full of surprises. Once the old shower comes out, we might find:
- Rot in the subfloor or wall framing from a slow leak
- Old galvanized or other dated supply lines
- Undersized or improperly vented drains
- Wiring that needs updating to meet current requirements
- Older materials that need testing before they can be disturbed
A careful design consultation reduces surprises but cannot eliminate them. A fair contract explains how hidden conditions are handled before work starts, so nobody is negotiating in the middle of a demolished room. We explain how we handle this in our process.
Permits
Many municipalities require permits for plumbing changes, electrical work and structural changes, while purely cosmetic work often does not need one. The rules differ between the City of Edmonton, the City of Prince George and surrounding communities, so check with your local building department or ask your contractor to confirm what applies. Permit and inspection time should be built into the schedule.
How to get a real number
Every one of these factors can push the price up or down. The way to turn "it depends" into an actual figure is to look at the room, decide on the scope and selections, and price it properly. That is what our in-home design consultation is for: we measure, take photos, ask how you use the space and what you are comfortable spending, then give you a fixed price in writing. You can read more about how that works in fixed pricing and staged payments.
