The Real-World Average Cost to Replace a Bathroom

Homeowners search “average cost to replace bathroom” every day, hoping for a simple number. In reality, costs swing from $7,500 for a compact powder room refresh to $35,000+ for a full primary suite overhaul. The goal of this guide is to unpack every factor behind those numbers and show how CountBricks turns guesswork into precise, voice-generated estimates for residential construction projects.

Key Factors Driving the Average Cost

1. Scope of Work

Replacing a bathroom can mean anything from a straight fixture swap to a down-to-studs reinvention. The larger the scope, the higher the labor hours, disposal fees, and inspection requirements.

• Remove & replace only toilet, vanity, and faucet: lower cost, minimal trades
• Add tub-to-shower conversion or relocate plumbing: moderate cost
• Full reconfiguration with new partitions, wiring, and HVAC: premium cost

2. Fixture & Finish Level

Material spend has a direct line to project total. Builder-grade fixtures might cost $2,000, while designer-grade packages can exceed $12,000. CountBricks’ live materials database pulls today’s pricing on everything from basic porcelain to smart toilets.

3. Labor Market Conditions

Skilled trades command competitive wages. In residential hubs such as St. Louis, CountBricks tracks local plumber, tile-setter, and electrician rates daily, then updates our cost library so you see true market numbers, not outdated averages.

4. Hidden Conditions

Mold behind tile, outdated venting, or subfloor damage can add 10-20 % once walls are open. Our AI prompts contractors to discuss risk factors during the initial voice walkthrough, so contingencies are baked into the estimate—not tacked on later.

Typical Cost Ranges

• Basic 5'×8' hall bath replacement: $7,500 – $12,000
• Mid-range family bath with new tub/shower unit, vanity, flooring: $13,000 – $22,000
• Luxury primary bath with custom tile, frameless glass, in-floor heat: $25,000 – $40,000+

These ranges include demo, fixtures, rough-in, finish, and standard permitting. Regional pricing differences are handled automatically inside the CountBricks engine.

Five Pro Tips from CountBricks Estimators

• Keep existing plumbing locations to avoid costly reroutes

• Use CountBricks variance reports to compare fixture alternatives side by side

Frequently Asked Questions

Is it cheaper to renovate or replace a bathroom?

Surface-level renovations (paint, fixtures) can be 40 % less than full replacement, but they may not solve hidden water damage. CountBricks helps you run both scenarios instantly.

How long does a replacement take?

• Powder room: 1-2 weeks
• Standard hall bath: 3-4 weeks
• Luxury primary bath: 6-8 weeks

Our construction scheduling module links tasks to live labor availability so you can forecast realistic timelines.

Will permits affect my budget?

Expect $200-$800 for permits, plan reviews, and inspections. CountBricks auto-populates local fees based on project scope.
