Full Bathroom Remodel Cost in 2026: What to Expect

This is the single biggest cost swing in a bathroom remodel. A prefab fiberglass tub-shower combo runs $200-$800 installed. A custom tile walk-in shower with frameless glass door pushes $5,000-$15,000. If you can keep your existing tub and just refinish it for $300-$600, you save thousands compared to a full replacement.

Basic ceramic tile starts at $0.50-$2 per square foot for materials. Porcelain runs $3-$10. Natural stone like marble or travertine jumps to $15-$35 per square foot. For a typical 75 sq ft bathroom with floor and shower walls, tile costs alone can range from $500 to $5,000+ depending on your choice.

A stock vanity from a big-box store runs $300-$800 including the top. Semi-custom options with quartz or stone tops land at $800-$2,000. Fully custom vanities with premium countertops and undermount sinks push $2,000-$3,800. Double vanities in a master bath cost roughly 50-75% more than a single.

Keeping fixtures in their current locations saves thousands. The moment you relocate a toilet, sink, or shower drain, you're looking at $1,500-$4,000 per fixture for new supply lines and drain routing. A full plumbing relayout in a master bath can hit $10,000-$15,000 in plumbing alone.

A small half bath (35 sq ft) remodels for $2,500-$8,000. A standard full bath (75 sq ft) runs $6,500-$18,000. A large master bathroom (150-200 sq ft) with separate shower, tub, and double vanity can easily reach $25,000-$55,000. Cost per square foot generally ranges from $75 to $275.

“What waterproofing method do you use in the shower area?”

Why this matters: Proper waterproofing (Kerdi membrane, RedGard, or similar) is critical. If a contractor can't explain their waterproofing system in detail, that's a red flag.

“How do you handle mold or water damage discovered during demo?”

Why this matters: Mold behind old tile and rotted subfloors are common surprises. You need to know their process and pricing for remediation before work begins.

“Will you inspect the subfloor before tiling?”

Why this matters: Tile installed on a weak or uneven subfloor will crack. A good contractor checks for deflection and levelness and will add cement board or replace damaged sections.

“What ventilation improvements do you recommend?”

Why this matters: Proper bathroom ventilation prevents future mold issues. A contractor who doesn't mention upgrading your exhaust fan may be cutting corners.

“What's your payment schedule?”

Why this matters: Red flag if they want more than 10-15% upfront. Standard is a deposit, then progress payments tied to milestones like rough-in completion and tile completion.

“Are you licensed, insured, and bonded?”

Why this matters: Verify their license number with your state licensing board. Insurance protects you if a worker is injured in your home.

“What warranty do you offer on labor and waterproofing?”

Why this matters: Most reputable contractors offer 1-2 year warranties on workmanship. Waterproofing failures can be catastrophic, so ask specifically about that coverage.
