How to Estimate Kitchen & Bathroom Remodels Without Losing Your Shirt (2026 Guide)

Kitchen and bathroom remodels are the highest-margin jobs most contractors will touch — and the easiest to lose money on. The difference between a $15K profit and a $5K loss comes down to how well you estimated the job before you started swinging a hammer. Here's everything you need to know.

Why Remodel Estimates Are Different

Unlike new construction where you're working from blueprints, remodels involve existing conditions — and existing conditions lie. That wall might have knob-and-tube wiring behind it. That subfloor might be rotted. The plumbing might not be to code.

This means your estimate needs to account for what you can see and what you might find. The contractors who survive do this well. The ones who don't end up working for free on change orders they didn't price.

Kitchen Remodel: What It Actually Costs in 2026

Budget Kitchen ($15,000–$30,000)

• Cabinets: Stock/RTA cabinets — $3,000–$6,000
• Countertops: Laminate or butcher block — $1,200–$2,500
• Appliances: Mid-range package — $2,500–$4,000
• Flooring: LVP or ceramic tile — $1,500–$3,000
• Backsplash: Subway tile — $800–$1,500
• Plumbing: New faucet, maybe relocate sink — $800–$2,000
• Electrical: Add outlets, under-cabinet lighting — $600–$1,500
• Labor: $4,000–$8,000 (2-3 weeks, small crew)

Mid-Range Kitchen ($30,000–$60,000)

• Cabinets: Semi-custom, soft close — $6,000–$14,000
• Countertops: Quartz or granite — $3,000–$6,000
• Appliances: Name brand (Bosch, KitchenAid) — $4,000–$8,000
• Flooring: Hardwood or high-end LVP — $2,500–$5,000
• Backsplash: Natural stone or designer tile — $1,500–$3,500
• Plumbing: Full rough-in changes possible — $2,000–$5,000
• Electrical: Panel upgrade, dedicated circuits — $1,500–$3,500
• Labor: $8,000–$16,000 (3-5 weeks)

High-End Kitchen ($60,000–$120,000+)

Custom cabinets, natural stone, professional-grade appliances, structural changes (removing walls, adding islands with plumbing), designer lighting. Labor alone can be $20K–$40K. These jobs need detailed specs and usually involve architects or designers.

Bathroom Remodel: What It Actually Costs in 2026

Half Bath / Powder Room ($5,000–$12,000)

• Vanity + top: $400–$1,500
• Toilet: $200–$600
• Flooring: $500–$1,200
• Paint + accessories: $300–$800
• Plumbing: $500–$1,500 (swap fixtures, no relocation)
• Labor: $2,000–$5,000 (3-5 days)

Full Bathroom ($12,000–$30,000)

• Tile (shower + floor): $2,500–$6,000
• Vanity + countertop: $800–$3,000
• Shower/tub: $1,000–$4,000 (prefab to custom tile)
• Toilet: $250–$800
• Plumbing: $1,500–$4,000
• Electrical: $500–$2,000 (exhaust fan, GFCI, lighting)
• Labor: $4,000–$10,000 (1-3 weeks)

Master Bath ($25,000–$60,000+)

Walk-in showers with linear drains, heated floors, double vanities, freestanding tubs, frameless glass enclosures. Labor-intensive tile work and waterproofing are where the real cost lives.

The 5 Categories Every Remodel Estimate Needs

1. Demo & Haul-Off

Don't forget demo. It's real labor and real dumpster costs. Budget $1,500–$3,000 for a kitchen demo, $800–$1,500 for a bathroom. Include dumpster rental ($300–$600/load).

2. Rough-In (Plumbing, Electrical, HVAC)

If you're moving anything — a sink, a toilet, ductwork — the rough-in costs add up fast. Moving a toilet 3 feet can cost $800–$2,000. Moving a gas line for a range: $500–$1,500. Always walk the job with your subs before quoting.

3. Materials (Finishes + Fixtures)

This is where scope creep kills you. Get the client to pick their finishes before you quote. “TBD” on the estimate means you're absorbing the difference when they pick the $40/sqft tile instead of the $8/sqft tile you budgeted.

Pro tip: Use allowances. “$3,000 allowance for countertop material. Upgrades at additional cost.” This protects your margin.

4. Labor

Remodel labor runs $50–$85/hr for skilled trades in most markets. Tile setters: $60–$100/hr. Electricians and plumbers: $75–$150/hr. Your crew: whatever you pay plus burden (workers comp, payroll taxes, insurance — usually 25-35% on top of wages).

5. Contingency & Unknowns

Always include 10-15% contingency on remodels. You will find something behind those walls. Mold, outdated wiring, rotted subfloor, asbestos tile. If you don't find anything — congratulations, that's extra profit. If you do, you're covered.

How to Write the Scope of Work

The scope of work on a remodel estimate is where lawsuits are won and lost. Be specific about what's included and what's not.

• “Demo existing kitchen cabinets, countertops, backsplash, and flooring. Haul to dumpster on-site.”
• “Install 14 LF upper cabinets and 18 LF base cabinets (client-supplied, RTA).”
• “Install 42 sqft quartz countertop with undermount sink cutout. Sink and faucet install included.”
• “NOT included: appliance purchase, permits, structural modifications, asbestos remediation if found.”

The NOT included section is just as important as the included section. It prevents the “I thought that was part of the job” conversation.

Change Order Process

Include your change order policy on every remodel estimate. Something like:

“Any changes to the scope of work after contract signing will be documented in a written change order with associated costs. Work on change orders will not begin until the change order is signed by both parties.”

This one paragraph will save you thousands of dollars over your career.

Markup & Profit Margins on Remodels

Industry standard for remodeling contractors:

• Material markup: 15-25% (covers ordering, storage, waste, returns)
• Labor markup: 35-50% (covers overhead, insurance, profit)
• Subcontractor markup: 10-20% (you're managing them — that has value)
• Overall profit margin: 20-35% target (after overhead)

If your net profit on a remodel is under 15%, you're not charging enough. Period. Factor in the callbacks, warranty work, and the 3 trips to the tile store because the client changed their mind.

Common Mistakes That Kill Remodel Profits

1. Not charging for design time. If you're spending 4 hours helping a client pick finishes, layout options, and drawing up plans — that's billable work. Charge a design fee or build it into your overhead.
2. Verbal change orders. “Oh, while you're in there can you also...” If it's not written down with a price, it didn't happen. Stop doing free work.
3. Underestimating tile labor. Tile is slow. A 100 sqft shower with niches, shelves, and a bench seat can take 3-5 days for one setter. Don't estimate it like you're laying floor tile in an open room.
4. No contingency. You will find something unexpected. Budget for it or eat it.
5. Quoting over the phone. Never give a remodel price without walking the job. Every. Single. Time.
