A complete bathroom remodel is not a cosmetic job. Everything comes out down to the framing, the plumbing and electrical are reworked to suit the new layout, the waterproofing is rebuilt from scratch, and the room goes back together in a fixed order that cannot be rushed. It is the most trade-dense room in a house, which is why a 50 square foot space costs what an entire bedroom would.
The single biggest decision is whether the layout moves. Keeping the toilet, tub and vanity in their existing positions keeps the drain work simple and can hold a project in the lower half of the range. Moving the toilet even three feet means opening the floor, re-cutting the drain at the right fall, and re-venting, which is where budgets move quickly.
What a full remodel actually replaces
Demolition takes the room to bare studs and subfloor, including the tub or shower base, all tile, the vanity, the toilet and usually the subfloor around the toilet flange, which is nearly always soft in an older house.
Rough-in follows: supply lines replaced or extended, drains re-cut and re-vented, new circuits for lighting, the exhaust fan and GFCI outlets, and blocking added in the walls for grab bars, a floating vanity, or a shower bench. Blocking is cheap now and impossible later.
Then waterproofing, which is the part nobody sees and everything depends on. A bonded waterproof membrane over the shower walls and pan, properly lapped and sealed at the corners and the drain, is the difference between a bathroom that lasts twenty years and one that rots the joists in five.
What moves the price
- Whether the layout moves. Keeping fixtures in place can save $3,000 to $8,000 in drain, vent and floor work alone.
- Tile choice and format. Large format and natural stone need a flatter substrate and more labour. Mosaic and herringbone multiply cutting time. The tile itself is often the smaller half of the cost.
- Shower type. A prefabricated base with a glass panel is far cheaper than a fully tiled curbless wet room, which needs the floor structure recessed to drain properly.
- What is behind the walls. Rotted subfloor at the toilet, failed supply lines, no exhaust vent, or knob and tube wiring are common in older Capital Region homes and are found at demolition, not before.
- Fixture level. Mid-range fixtures and a quality vanity sit at one end. Wall-hung toilets, thermostatic valves, custom glass and stone tops sit at the other.
The sequence, and why it cannot be reordered
- Design and selections. Every fixture, tile and finish chosen and on site before demolition. Waiting on a vanity mid-project stops everything behind it.
- Permit. Plumbing and electrical work on a full remodel requires a permit in every Capital Region municipality.
- Demolition. Two to three days. This is when surprises surface.
- Rough plumbing and electrical. Three to five days, followed by inspection before anything is closed.
- Waterproofing and substrate. Membrane, backer board, and a flood test on the shower pan before tile goes anywhere near it.
- Tile. The longest single phase, one to two weeks depending on format and pattern, with curing time between setting and grouting.
- Fixtures, glass and finish. Vanity, toilet, trim, paint, and glass last, because glass is measured to the finished tile, not to the drawing.
Mistakes we see most often
- Choosing tile after demolition starts. Lead times on anything not in stock will idle the job for a week or more.
- Skipping the shower pan flood test to save a day. It is the only chance to find a leak before it is buried under tile.
- Forgetting blocking for grab bars. Even if nobody needs one now, adding it during rough-in costs almost nothing and retrofitting means opening finished walls.
- Undersizing the exhaust fan or venting it into the attic instead of outside. In an Upstate winter that puts a bathroom worth of moisture into your roof structure every day.
What this means in the Capital Region
Capital Region housing stock cuts both ways here. In Troy, Albany and Cohoes the bathrooms are often original to houses built between the 1880s and 1920s, with cast-iron waste stacks, galvanised supply lines and no exhaust ventilation at all. Those projects almost always turn up more work behind the walls than the drawing shows, and a contingency of 10 to 15 percent is realistic rather than pessimistic.
In the post-war housing of Clifton Park, Colonie, Guilderland and East Greenbush, the structure is usually sound and the work is closer to what was quoted. The common find there is an undersized panel that cannot carry a new circuit for heated floors without an upgrade.
Heated tile floors are worth mentioning specifically. In a climate with six cold months they are one of the few upgrades people describe as worth every penny afterwards, and the electric mat systems add far less to a project than most homeowners assume when it is done during a full remodel rather than retrofitted.

Frequently asked questions
How long is the bathroom unusable?
For a full remodel, the entire four to seven weeks. There is no stage where the room is partly usable, because the plumbing is disconnected from demolition until fixtures go back at the end. If it is the only bathroom in the house, plan for that before work starts.
Can I keep my existing tub?
Sometimes. A cast-iron tub in good condition is worth keeping and can be refinished. The catch is that the tub has to be protected through demolition and tiling, which constrains the sequence, and if the surround is being retiled the tub flange usually needs to come out anyway. We will tell you honestly whether it is worth it in your case.
Do I need a permit for a bathroom remodel?
Yes, if plumbing or electrical work is involved, which it is in any full remodel. Every Capital Region municipality requires it. Mastaba prepares and files the package and manages the inspections.
Is a curbless shower worth it?
It looks excellent and it is genuinely better for ageing in place, but it requires the floor structure to be recessed so the shower drains without a curb. In a house with an accessible crawlspace or basement below, that is very doable. On a slab or over a finished ceiling it gets expensive quickly.
What should I not cheap out on?
Waterproofing, the exhaust fan, and the valve behind the wall. All three are invisible, all three are expensive to redo, and all three are where failures come from. Save on the vanity and the light fixture instead, since both can be swapped in an afternoon later.
