Most people arrive with a number in their head and no sense of what it reaches. Here is what each tier genuinely covers, and where spending more changes the room rather than just the price.
What decides which tier you are in
Two things set the cost of a bathroom before any tile is chosen. Whether the plumbing moves, and whether the room gets bigger.
Leave the toilet, sink and drain where they are and you are replacing surfaces. Move the shower to the other wall and you are opening the floor, rerouting waste lines and, in an older Chicago house, probably discovering the stack is cast iron.
Surfaces are predictable. Plumbing that moves is where the number goes.
Around fifteen thousand
Same footprint, same plumbing locations. New tub or shower in the existing opening, new vanity, new toilet, new floor and wall tile, new lighting and exhaust fan, paint.
This is a real remodel and it transforms a dated bathroom. What it does not do is fix a bad layout, and it rarely survives the discovery of rot under a forty-year-old shower pan without a change order.
- Stock or semi-custom vanity, quartz or cultured-marble top.
- Porcelain floor tile, tiled tub surround to the ceiling.
- New fan ducted properly to the outside, not into the attic.
- No framing changes and no plumbing relocation.
Around thirty-five thousand
The layout can change. A tub comes out and a curbless shower goes in, the vanity grows to a double, the door swing is corrected, a linen closet appears where a dead corner used to be.
This is the tier where a primary bathroom starts to feel designed rather than updated. It is also where most Hinsdale and Barrington primary baths land once the owners have seen what an extra foot of shower does.
- Plumbing relocation and new supply lines.
- Custom or furniture-grade vanity with undermount sinks.
- Larger-format tile, a tiled niche, a glass shower enclosure.
- Heated floor, cheap to add while the floor is open and expensive to retrofit later.
Seventy thousand and above
At this level the bathroom usually borrows space from a bedroom or a closet, which means framing, structural review and sometimes a window moved on the exterior.
The fittings change category too. Thermostatic valves, a freestanding tub with a floor-mounted filler, stone slab rather than tile on the shower walls, cabinetry built for the room rather than sized to fit it.
Above about seventy thousand you are buying square footage and stone, in that order.
What is worth moving up a tier for
If you are choosing between a better faucet and a bigger shower, take the shower. If you are choosing between slab stone and fixing the layout, fix the layout.
The upgrades people are still glad about five years later are almost always spatial. Room to dry off outside the shower. Two sinks far enough apart to use at once. A door that does not hit the vanity.
- Correcting the layout beats any finish upgrade.
- Waterproofing you cannot see is the one invisible thing worth paying for.
- A heated floor, while the floor is already open.
- Lighting on more than one switch, so the room works at 6am and at 10pm.
Getting a number you can trust
A bathroom quote with no allowance schedule is a guess. Ask what the tile allowance is per square foot, what the vanity allowance is, and what happens if the subfloor turns out to be bad.
We write those three things into every bathroom estimate because they are the three that move. Everything else is labour, and labour we can price accurately.
