Bathroom Remodel Cost Calculator

How much does a bathroom remodel cost?

A bathroom remodel in 2025 typically costs $8,000–$20,000 for a hall or guest bathroom and $18,000–$45,000 for a primary bath. Luxury spa-style masters with steam showers, freestanding tubs, and heated floors regularly clear $60,000–$100,000. Bathrooms are dense with plumbing, electrical, tile, and waterproofing — which is why the cost per square foot is 2–3× a kitchen's. Our calculator estimates your project by fixture count, finish tier, and ZIP-code-adjusted labor.

What you're paying for

• Labor — 40–50% of total. More trades per square foot than any other remodel: plumber, electrician, tile setter, drywall, paint, and often a general contractor.
• Tile and stone — 10–20%. Ceramic $8–$15/sq ft installed, porcelain $12–$20, natural stone $18–$40.
• Vanity and countertop — 8–15%. Stock vanity + top $500–$1,200; custom vanity with stone $2,500–$8,000.
• Fixtures (toilet, sink, faucets, shower valve) — 8–15%. Budget package $500–$1,000; premium (Toto, Kohler Purist, Grohe) $3,000–$8,000.
• Shower or tub — 10–20%. Prefab acrylic surround $1,500–$3,500; custom tile shower $4,500–$12,000; freestanding tub $1,000–$5,000 plus install.
• Waterproofing, plumbing rough-in, permits — 5–10%.

Three project types

Cosmetic refresh ($4,000–$9,000) — New paint, mirror, light fixture, faucet, toilet, vanity, and re-glaze the existing tub. No plumbing moves. 1–2 weeks.

Full pull-and-replace, same footprint ($12,000–$25,000) — New tile floor, new shower or tub-shower combo, vanity, toilet, lighting, exhaust fan. Plumbing stays put. 3–5 weeks.

Layout change or spa bath ($30,000–$80,000+) — Walls moved, tub-to-shower conversion or freestanding tub added, curbless shower, heated floors, custom vanity, dual sinks. 6–10 weeks.

How to use the calculator

Select the bath size, whether it's a full bath or half bath, your fixture and finish tier, and whether you're keeping or moving plumbing. Enter your ZIP for regional labor adjustment. The calculator returns a low-mid-high range and breaks out labor, materials, and fixtures so you can see where trade-offs pay off.

Where the money actually goes

Homeowners are often surprised that the shower is the single most expensive element in a bathroom. A properly built curbless tile shower includes:

• Waterproof membrane (Schluter, Wedi, or hot mop)
• Sloped mortar bed
• Linear drain and vapor barrier
• Tile setter labor at $12–$20/sq ft
• Glass enclosure $1,200–$3,500

Skimping on waterproofing is the number one cause of expensive callbacks — a failed pan can require gutting the shower and repairing the ceiling below.

Tub vs. shower — the resale question

For primary bathrooms, having at least one tub somewhere in the house matters for resale (families with young kids expect it), but the primary bath itself doesn't need one. Tub-to-shower conversions are one of the most requested remodels among 45+ homeowners and generally add value if there's a tub elsewhere.

Common ways bathroom budgets balloon

1. Old cast iron drain lines. Once you open the wall, code often requires replacing them — add $1,500–$4,000.
2. Subfloor rot. A leaking wax ring for 5 years quietly rots the subfloor around the toilet — $500–$2,000 to repair.
3. Non-standard tile sizes. Large-format tile ($30"×$30$ or bigger) requires a perfectly flat substrate; leveling the floor can add $500–$1,500.
4. Custom glass. Frameless shower enclosures with 3/8" glass are $80–$120/sq ft; a walk-in with two panels can be $2,500–$4,500.

Smart money-saving moves

• Keep the plumbing footprint. Every fixture you move is $500–$1,500 in rough-in labor.
• Standard-size vanities. A 30", 36", or 60" stock vanity costs a fraction of a custom build and looks just as good.
• Porcelain that looks like stone. Marble-look porcelain is $12–$18/sq ft installed vs. $30–$50 for real marble — and doesn't etch or stain.
• Splurge on one focal point. Big statement tile in the shower, plain subway everywhere else.
• Reuse the exhaust fan and rough-in if it's up to code. New fan install runs $300–$700 if wiring is already there.

Timeline reality check

A pull-and-replace bathroom is out of service for 3–5 weeks — not the "2 weekends" homeowners often expect. Tile floors require mortar cure time, waterproofing needs to test-flood, and inspectors don't come the day you call. Budget alternate bathroom access or plan around it.

What's not included

Our estimate covers construction cost. It excludes design consultation ($1,500–$5,000), permits ($200–$800), and any structural work like removing a load-bearing wall (usually adds $2,500–$6,000 for the beam and engineering). Add a 10–15% contingency for older homes.

Financing and permits

Most bathroom remodels require permits when moving plumbing or electrical. Expect a rough-in inspection before drywall closes and a final inspection before tile grouting. HELOCs and cash-out refis are the cheapest financing for renovations over $15,000; contractor financing is usually the most expensive.

After construction

Silicone joints (tub-to-wall, corners) need annual inspection and re-caulking every 3–5 years. Grout should be sealed 30 days after install and re-sealed yearly in showers. A quality exhaust fan (110+ CFM, timer-controlled) run 20 minutes after every shower is the single biggest predictor of long-term tile and drywall life.

Resale ROI

Cost vs. Value puts mid-range bath remodels at 65–75% ROI within 5 years. Universal design features (curbless shower, grab-bar blocking, comfort-height toilet) are increasingly requested by 55+ buyers and cost little to add during a full remodel.
