How to Start a Bathroom Remodeling Business on a Lean Budget

Bathroom remodels are the second most popular home renovation project in America (behind kitchens), and the average project costs $12,000 to $25,000. Unlike kitchens, bathrooms are smaller spaces with faster turnaround times. A skilled crew can complete 2 to 3 bathroom remodels per month, generating $30,000 to $60,000 in monthly revenue.

Christina, a tile installer in Nashville, started her bathroom remodeling company in 2024 with $11,000 in savings. She focused exclusively on bathrooms (no kitchens, no additions, no general contracting). That focus became her competitive advantage. "When homeowners search for bathroom remodeling, they want a specialist, not someone who does everything," she said. She completed 22 bathrooms in her first year and grossed $374,000.

How Much Does It Cost to Start a Bathroom Remodeling Business?

Plan for $8,000 to $25,000:

Licensing: $300 to $2,000 (varies by state)
Insurance: $2,000 to $5,000 per year
Vehicle: $4,000 to $10,000 (used cargo van or pickup)
Tools: $1,500 to $4,000
Marketing: $1,000 to $3,000 (portfolio website, Google Business Profile)
Working capital: $2,000 to $8,000

Bathroom remodeling requires less working capital than kitchen remodeling because the project values are lower and timelines are shorter. You can often collect enough in deposits to cover materials before work begins.

What Licenses and Certifications Do You Need?

Similar to kitchen remodeling, bathroom work falls under general contracting in most states:

General contractor or remodeling contractor license (where required by your state)
EPA lead-safe (RRP) certification for homes built before 1978
Plumbing work: In most states, moving or adding plumbing fixtures requires a licensed plumber. You can subcontract this work or, in some states, add a plumbing category to your contractor license.

Valuable certifications:

NKBA (National Kitchen & Bath Association) certification
NARI Certified Remodeler
Certified Aging-in-Place Specialist (CAPS) from NAHB (opens up the growing senior market)

The CAPS certification is especially valuable. Over 10,000 Americans turn 65 every day, and many need bathroom modifications (grab bars, walk-in showers, comfort-height toilets). This niche is underserved and growing rapidly.

Partner with plumbing companies. Plumbers encounter bathrooms that need remodeling every day. Offer a referral fee ($200 to $500) for every remodel lead that converts. Many plumbers are happy to refer work they do not want to manage.

Target homes built in the 1990s. These homes have 25 to 30 year old bathrooms with builder-grade finishes. The owners have equity and are ready for upgrades. Direct mail to these neighborhoods performs well.

Mistakes That Kill New Bathroom Remodeling Businesses

Discovering hidden problems too late. Old bathrooms hide water damage, mold, and outdated plumbing. Always include a contingency clause in your contract (5% to 10% of project cost) for unexpected issues discovered during demolition.

Not waterproofing properly. A leaking shower will destroy your reputation faster than anything else. Use proper waterproofing membranes (Kerdi, RedGard, or similar) on every shower and tub surround. Never cut corners on waterproofing.

Underestimating tile labor time. Tile work is time-intensive. A 50 square foot shower with subway tile can take 2 to 3 days of labor. Price tile work by the square foot ($8 to $15 per square foot installed for standard tile, $15 to $25 for mosaics and complex patterns).

Not managing client selections. Homeowners who cannot decide on tile, fixtures, or paint colors will delay your project by weeks. Set a "selections deadline" in your contract: all materials must be chosen by a specific date, or the start date moves.

Frequently Asked Questions

Is bathroom remodeling profitable?

Very. Bathroom remodels offer 30% to 40% gross margins, faster turnaround than kitchens (1 to 3 weeks vs. 4 to 8 weeks), and high demand. A solo bathroom remodeler completing 2 to 3 projects per month can earn $100,000 to $180,000 per year.

Do I need plumbing and electrical licenses for bathroom remodeling?

In most states, you need licensed subcontractors for plumbing and electrical work unless you hold those licenses yourself. You can manage the overall project under your GC license and sub out the specialized trades.

What is the most popular bathroom remodel request?

Tub-to-shower conversions and walk-in showers are the most requested bathroom upgrades. The trend toward open, curbless showers has been growing steadily. Aging-in-place modifications (grab bars, bench seats, handheld showerheads) are the fastest-growing segment.

How many bathroom remodels can one person do per month?

A skilled solo remodeler can complete 2 to 3 standard bathroom remodels per month. With a helper, you can handle 3 to 4. With a full crew of 2 to 3, you can manage 4 to 6 projects monthly by overlapping demo, tile, and finish phases.
