The three tiers, line by line
National averages hide more than they reveal, so here's the same bathroom priced three ways. Assume a standard 5×8 full bath, materials and labor combined:
| Line item | Budget refresh | Mid-range gut | High-end |
|---|---|---|---|
| Labor (all trades) | $2,500–4,000 | $6,000–12,000 | $15,000–25,000 |
| Tile & flooring | $800–1,500 | $2,000–4,500 | $5,000–10,000 |
| Vanity & countertop | $400–1,200 | $1,500–3,500 | $4,000–8,000 |
| Shower/tub & glass | $600–1,500 | $2,500–6,000 | $7,000–15,000 |
| Plumbing fixtures | $300–800 | $1,000–2,500 | $3,000–6,000 |
| Toilet | $150–350 | $350–700 | $700–2,000 |
| Lighting & electrical | $200–500 | $600–1,500 | $1,500–3,500 |
| Paint, drywall & trim | $150–400 | $400–900 | $900–2,000 |
| Everything else | $400–800 | $900–2,000 | $2,000–4,000 |
Two things jump out. First, labor is the biggest single line in every tier — typically 40–60% of the total for a gut remodel, which is why a DIY-managed project with hired trades for plumbing and tile can cost half of a turnkey quote. Second, the "everything else" row is real money: cement board, waterproofing membrane, valve trim, exhaust fan, grab-bar blocking, shims, caulk, and transition strips are individually cheap and collectively a four-figure line in a gut remodel.
The shower glass deserves its own warning: frameless glass is measured after the tile is done and then takes 2–4 weeks to fabricate — it's both a four-figure line item and the most common reason a "finished" bathroom sits unusable. The full timeline is in how long a bathroom remodel takes.
Where the materials money actually goes
Strip labor out and the materials budget splits with surprising consistency:
| Category | Share of materials budget | Notes |
|---|---|---|
| Tile (floor, walls, shower) | 25–35% | Quantity math matters — see the shower-tile guide. |
| Vanity, top & mirror | 15–25% | Stock vs. custom swings this line the most. |
| Shower system & glass | 15–25% | Valve, trim, door or panel. |
| Plumbing fixtures & toilet | 10–15% | Faucet, tub filler, toilet. |
| Lighting & ventilation | 5–8% | Vanity lights, exhaust fan. |
| Paint & trim | 3–5% | Use a bathroom-rated paint — moisture is the enemy. |
| Everything else | 8–12% | Waterproofing, backer board, fasteners, caulk… |
If you're pricing tile, don't guess the quantity — the waste factors and the worked example in how much tile a shower needs will keep you from ordering a dye lot short. For the paint line, a quart of ordinary wall paint isn't the move in a wet room; a scrubbable, moisture-tolerant finish — or a low-VOC bathroom paint if you're sensitive to fumes in a small unventilated space — costs a few dollars more and repaints years later.
Set the contingency before demo day
Bathrooms hide surprises behind tile — subfloor rot around the toilet flange, galvanized supply lines, a vent stack where the niche was supposed to go — so plan 15–20% on top of your line-item total for a gut of an older bath. The full logic for sizing it is in the renovation contingency guide.
Three habits that keep the number honest
- Price the complete list, not the highlight reel. A budget built from every checklist row — including backer board and the exhaust fan — starts honest. One built from vanity + tile + tub starts 20% underwater.
- Track estimated and actual separately. Window-shopped prices are plans; ordered items are commitments, and the gap between them is your remaining exposure — the two-column method is worked through in the budget breakdown guide.
- Get line-item quotes, not lump sums. A single "$28,000, all-in" quote can't be compared or trimmed. Ten labor lines and a materials allowance can — and trimming selections is the only mid-project lever you really have.
