Start to Finish Tub to Shower Conversion

Daddicated takes homeowners through a complete guest bathroom remodel from start to finish, including a full tub to shower conversion, showing every stage of the process and what the project actually costs at each step.

Bathroom Renovation Cost Breakdown: Where the Money Actually Goes

Most bathroom renovation budgets fall apart not because homeowners spend too much but because they did not know what they were paying for when they agreed to the number. A quote arrives, it looks reasonable, and then change orders start coming and the final invoice looks nothing like the original.

This guide breaks down exactly where bathroom renovation money goes, what each category typically costs, which decisions move the number most, and how to read a contractor quote so you understand what you are actually agreeing to before work begins.

The Full Cost Breakdown by Category

A complete bathroom renovation budget typically divides across these categories. The percentages below reflect a standard mid-range remodel. Premium finishes shift the mix but the structure stays similar.

Labor: 40 to 65 Percent of Total Cost

Labor is almost always the largest line item and the one that surprises homeowners most. Bathroom renovations require multiple licensed trades — plumbers, electricians, tile setters, and carpenters — each billing at different rates. In most US markets expect to pay:

Plumbers: $75 to $150 per hour

Electricians: $65 to $130 per hour

Tile setters: $50 to $120 per hour

General labor and carpentry: $40 to $90 per hour

A standard bathroom remodel involves all of these trades at various stages. The tile setter alone may spend 20 to 30 hours on a mid-size bathroom depending on the tile chosen and the complexity of the layout. That one trade at $80 per hour is $1,600 to $2,400 before materials.

This is why keeping the existing plumbing layout saves so much. Every hour a plumber spends moving pipes is an hour at $75 to $150 that goes directly to labor cost with no visible result in the finished room.

Tile and Flooring: 15 to 20 Percent

Tile is the most visible material decision in a bathroom renovation and the one where cost varies most widely. The material cost alone ranges from $2 to $30 per square foot depending on the tile. But the installation cost is where decisions compound.

A standard subway tile in a running bond pattern is the most efficient to install. Large format tile requires more precision and more time. Mosaic tile takes significantly longer to set. A herringbone or diagonal pattern adds installation hours on top of any tile choice because every piece requires a diagonal cut.

Floor tile and wall tile are typically priced separately because the installation methods differ. Heated floor systems add cost in materials and in electrical work to connect the thermostat.

Budget for 10 to 15 percent extra tile beyond your square footage for cuts and breakage. A contractor who quotes exactly to the square footage of the room is not accounting for waste.

Vanity and Countertop: 10 to 15 Percent

The vanity is the furniture of the bathroom and the range is enormous. A builder-grade vanity with a cultured marble top runs $300 to $600. A mid-range solid wood vanity with a quartz top runs $1,200 to $2,500. A custom built vanity with stone countertop can reach $4,000 to $8,000 or more.

The countertop material matters beyond aesthetics. Cultured marble is affordable and durable. Quartz is more expensive but resists staining better. Natural stone is the premium option and requires sealing to maintain in a wet environment.

The sink style affects cost too. A drop-in sink is the least expensive installation. An undermount sink requires a solid surface countertop and more precise cutting. A vessel sink sits on top of the counter and needs a taller faucet to match.

Shower or Tub: 10 to 20 Percent

The shower or tub is where some of the most significant budget decisions are made and where the difference between project types is most visible.

A prefabricated shower surround or tub surround costs $300 to $1,500 for the unit and relatively little to install. It is the fastest and most affordable option.

A tile shower with a prefab pan runs $1,500 to $4,000 in materials and installation combined depending on tile choice and size.

A fully custom tile shower with a mud bed floor, niche, bench, and frameless glass door runs $5,000 to $12,000 or more depending on size and finish level. The glass door alone on a frameless enclosure runs $800 to $2,500.

A tub to shower conversion like the one covered in the video linked above involves removing the existing tub, waterproofing the pan, and installing a custom shower in the alcove. It typically runs $3,000 to $7,000 depending on tile and fixture choices.

A freestanding soaking tub adds $800 to $5,000 in fixture cost alone, plus plumbing labor to connect a floor-mounted filler.

Plumbing Fixtures: 5 to 10 Percent

Fixtures are the items you touch every day — toilet, faucets, showerhead, tub filler. The range from builder-grade to premium is wide but the installation labor is the same regardless of what you choose.

A builder-grade toilet runs $150 to $300. A comfort-height elongated toilet with a soft-close seat runs $300 to $700. A wall-hung toilet requires a carrier frame installed inside the wall and runs $800 to $1,500 installed.

Faucets range from $80 to $600 depending on finish and brand. The finish — chrome, brushed nickel, matte black, unlacquered brass — affects both price and how it shows fingerprints and water spots over time.

Matching all fixtures to the same finish throughout the bathroom reads as intentional and considered. Mixing finishes is increasingly common but requires deliberate choices to work.

Electrical and Lighting: 5 to 8 Percent

Bathroom electrical work requires a licensed electrician in most jurisdictions and must meet GFCI requirements near water sources. Budget for this even if your existing electrical is adequate — permits and inspections are part of any proper bathroom renovation involving electrical work.

Lighting choices affect both cost and the feel of the finished room significantly. Recessed lighting, a vanity bar, and a separate shower light are a standard package. Heated towel bars and exhaust fans with humidity sensors add cost but improve daily function in ways homeowners notice.

Demo and Disposal: 3 to 5 Percent

Demo is labor and disposal is a dumpster or haul-away service. Both are real costs that sometimes get buried in contractor quotes. Ask specifically whether demo and disposal are included in the quote and what happens if hidden conditions — water damage, mold, outdated wiring — are found during demo.

A contractor who has a clear documented process for handling scope changes discovered during demo is showing you something important about how they operate.

Permits: 1 to 3 Percent

Any bathroom renovation involving plumbing or electrical changes requires a permit in most US jurisdictions. Permit fees vary by municipality but typically run $200 to $800 for a bathroom project. A contractor who offers to skip permits to save money is creating a liability for you at resale and in the event of an insurance claim.

How to Read a Contractor Quote

A single-number quote tells you almost nothing. A properly itemized quote breaks out every category — demo, tile labor, tile materials, plumbing labor, fixtures, electrical, vanity, countertop, shower unit, glass, permits, and cleanup — as separate line items.

When you have itemized quotes from multiple contractors you can see exactly where differences are coming from. One contractor may be cheaper on labor but quoting a lower-grade tile. Another may include permit fees that a competitor left out. The total number is the last thing to compare. The line items are where the real evaluation happens.

Ask every contractor to match the same scope of work when quoting. Different scopes produce different numbers and comparing them is meaningless.

Final Thoughts

A bathroom renovation is one of the more complex home improvement projects because decisions in one category affect costs in others. The tile you choose affects labor hours. The plumbing layout you keep or change affects the entire project cost. The contractor you hire determines whether the finished result looks like the quote promised.

Going into the project with a clear understanding of where money goes in each category gives you a foundation for making decisions that match your priorities and your budget.

Frequently Asked Questions

What is the biggest cost in a bathroom renovation?

Labor is the largest category at 40 to 65 percent of the total budget. Tile setters, plumbers, and electricians all bill at $50 to $150 per hour. After labor, tile and flooring and the vanity and countertop are typically the next largest expenses.

How much does bathroom tile cost?

Tile material ranges from $2 to $30 per square foot depending on type and quality. Installation adds $50 to $120 per hour in labor. Complex patterns like herringbone or diagonal cuts add installation hours on top of material cost. Budget 10 to 15 percent extra for cuts and waste beyond your room's square footage.

What does a tub to shower conversion cost?

A tub to shower conversion typically runs $3,000 to $7,000 depending on tile selection, shower size, and fixture choices. The range moves based on whether you choose a prefab pan or a custom mud bed floor, what tile you use on the walls, and whether you add a frameless glass door.

Do I need a permit for a bathroom renovation?

Any renovation involving plumbing or electrical changes requires a permit in most US jurisdictions. Permit fees typically run $200 to $800. A contractor who skips permits creates liability for you at resale and in the event of an insurance claim. Always confirm permits are included in the scope of work.

How do I compare bathroom renovation quotes?

Ask every contractor for an itemized quote that breaks out demo, tile, plumbing, electrical, fixtures, vanity, countertop, shower, permits, and cleanup as separate line items. Make sure every contractor is quoting the same scope of work. Compare line items before totals — the total number is the last thing to evaluate.

What is the most cost-effective shower option?

A prefabricated shower surround is the most affordable option at $300 to $1,500 for the unit with minimal installation cost. A tile shower with a prefab pan is the mid-range option at $1,500 to $4,000. A fully custom tile shower with mud bed floor and frameless glass runs $5,000 to $12,000 or more.

How much does a vanity cost for a bathroom renovation?
