What a bathroom remodel actually costs

The short answer

Three jobs get called “a bathroom remodel” and they are not the same project. Find yours first, because the gap between them is larger than any material choice you will make.

These are national ranges for a contractor-run job with permits pulled. Labor is the part that swings hardest by geography — the same bathroom can run 30 percent either side of these figures depending on your market. Treat them as a way to sanity-check a quote, not as a quote.

Where the money actually goes

People walk into this expecting tile to be the expensive part. It rarely is. On a typical full remodel of a standard 5×8 hall bathroom, the split looks roughly like this.

The useful thing to take from that table is the first row. If labor is half the job, then decisions that add labor hours cost you far more than decisions that add material cost. A tile that is two dollars a square foot dearer might add $200 to a bathroom. A tile that takes longer to set adds thousands.

The four decisions that move the number most

1. Moving plumbing

Leaving the toilet, sink and shower drain where they are is the single biggest saving available to you, and it is usually invisible in the finished room. Relocating a drain means opening the floor, re-running waste lines at the correct fall, and inspection. Expect $1,500 to $5,000 before a single tile is set, more if you are on a concrete slab.

It is sometimes worth it — a badly placed toilet you squeeze past every morning is worth fixing. Just make it a deliberate purchase rather than something that happens because a drawing looked nicer.

2. Tile size and pattern

The tile itself is a modest line item. What you do with it is not. A straight-set 12×24 on a flat floor is fast. The same tile in herringbone, or a mosaic with fifty times the grout lines, or a large-format slab that needs levelling clips and two people to place, is slow — and slow is billed.

As a rule of thumb, running a pattern rather than a straight set adds 15 to 40 percent to installation labor, and it also raises the waste allowance you have to order. If you want the pattern, put it somewhere small and seen — a shower niche, the floor of a powder room — rather than across every surface.

3. Turning a tub into a shower

Popular, and rarely as simple as it sounds. The drain moves, the valve height changes, the opening usually needs framing, and a properly built shower pan with a waterproofing membrane is genuinely more work than dropping in an alcove tub. Budget $2,000 to $6,000 over a like-for-like tub replacement.

One caution that has nothing to do with money: if it is the only bathtub in the house, removing it can hurt you at resale in a family neighborhood. Buyers with small children filter listings on it.

4. Curbless showers and heated floors

Both are lovely and both are structural. A curbless shower requires the floor to be recessed or the whole bathroom floor built up so water runs the right way; on a second storey that means working with the joists. Heated floor is a reasonable-sounding upgrade that pulls in an electrician, a dedicated circuit and a thermostat. Each realistically adds $1,500 to $4,000.

What costs less than people expect

• Going up the wall. Tiling a shower to the ceiling instead of stopping at 72 inches is a few extra square feet of material and an hour or two of labor. It is one of the cheapest ways to make a bathroom look expensive.
• Better fittings. The jump from a builder-grade faucet to a good one is often $150–$300, on a job costing twenty thousand. It is the thing your hand touches every day.
• Paint. Genuinely cheap, genuinely transformative, and the last decision you should make rather than the first — match it to the tile you chose, never the other way round.
• A larger mirror. Costs tens of dollars more than a small one and changes how big the room feels more than most structural work.

How to get quotes you can compare

Three bids on a vague description are three different bathrooms, and comparing their prices tells you nothing. Before you call anybody, write down:

1. Whether the layout is changing, and specifically whether any drain moves.
2. The exact tile for each surface — floor, shower walls, shower floor — with the size and pattern named.
3. Who supplies materials, you or them, and who eats it if something is backordered.
4. What happens to the existing floor and subfloor.
5. Where the shower glass comes from, and whether it is in the price or a separate trade you will be billed for later.

Hand the same sheet to every bidder. The prices become comparable, and the bidders take you more seriously — a homeowner who knows what they want is a cheaper job to run, and good contractors price that in.

Budgeting for the thing behind the wall

Bathrooms hide water damage. Once the tile comes off, it is common to find a rotted sill plate, a leaking supply line, or a shower pan that has been quietly failing for a decade. None of that is in anybody's quote, because nobody could see it.

Hold back 10 to 15 percent of your budget and do not spend it on upgrades. If the walls open up clean, you have a bonus. If they do not, you have the thing that stops a remodel stalling half-finished, which is the genuinely expensive outcome.
