How to Quote a Bathroom Tile Job From Walkthrough to Signed Estimate (The Full Contractor Process)

By Nico R. • April 19, 2026 • estimating quoting bathroom walkthrough pricing line items

Quoting a bathroom tile job looks simple from the outside. You walk the space, write some numbers down, send an email.

The reality is that a bathroom walkthrough has twenty things to check, eight decisions that affect your price, four traps that will cost you money if you miss them, and roughly one homeowner in three who has no idea what they actually want yet.

This is how I run a bathroom walkthrough after 14 years of tiling bathrooms. By the end, you'll know what to ask, what to measure, what to photograph, what gotcha items to price separately, and how to structure an estimate that protects your margin when the scope changes mid-job — which it always does.

The 45-Minute Bathroom Walkthrough Timeline

For a standard primary bath or ensuite, 45 minutes is the right budget. Less than that and you're missing things. More than that and you're doing free consulting.

• First 10 minutes: Meet the homeowner, understand the vision
• Next 15 minutes: Measure everything, photograph everything, check structural details
• Next 10 minutes: Discuss materials, tile selection, confirm scope
• Final 10 minutes: Timeline expectations, your process, questions

This is also the phase where you position yourself as the professional running the full estimating process. Stick to the timeline. A focused 45-minute walkthrough tells the homeowner you know what you're doing.

The Questions to Ask in the First 10 Minutes

Before you measure anything, understand what you're actually quoting.

Scope questions:

• "Are we doing the whole bathroom, or just the shower?" — Your first fork. A full bathroom remodel is 3–5× the scope of shower-only.
• "Is the shower becoming a walk-in, or staying the same configuration?" — Walk-ins with no curb require linear drains, different waterproofing, different pricing.
• "Are you keeping the existing vanity and toilet, or replacing them?" — Affects demo scope, access, and order of operations.
• "Who is doing the plumbing work?" — You are not doing plumbing unless licensed. Coordinate with their plumber or recommend one.
• "Who is doing the electrical?" — Same as plumbing. Heated floors need an electrician.

Tile and material questions:

• "Have you picked tile, or are you still deciding?" — Decided tile means accurate pricing. Undecided tile means pricing on an assumption, clearly noted.
• "What size and pattern are you thinking?" — 12×24 straight lay is a different job from 2×2 herringbone marble mosaic. Herringbone pricing specifically is 150–175% of straight lay — the pattern drives the price.
• "Do you want heated floors?" — Adds material, labor, and electrical coordination.
• "Any natural stone?" — Natural stone needs specific thinset, sealers, and careful handling. If there's a marble shower pan, preslope failure causes marble to darken permanently — flag this early and price it properly.

Timeline questions:

• "When are you looking to start?" — Their timeline affects your scheduling.
• "Is there a hard deadline?" — "We need it done before my daughter's wedding" is different from "whenever."
• "How many bathrooms does the house have?" — One bathroom means more urgency than three.

The Measurement and Documentation Phase

Now you measure. Be methodical.

What to measure:

• Floor: Length × width, subtract the footprint of vanity, toilet, and shower pan
• Shower pan: Length × width; note if walk-in or traditional, drain location (center, offset, linear)
• Shower walls: Height from curb top to ceiling or top of wall tile; width of each wall — front, back, left, right; note niches, benches, window openings
• Curb: Length, width (usually 4–6" wide), height from floor
• Backsplash: Length and height; note outlets, faucet cutouts

What to photograph:

• Wide shots of every wall from multiple angles
• Close-ups of the floor and existing tile
• The subfloor if visible (plywood type or concrete slab)
• Any damage, water stains, or existing issues
• The shower plumbing rough-in and current drain configuration
• Doorway transitions
• The window in the shower, if present (a $350–500 line item you don't want to discover mid-job)

Take more photos than you think you need. Storage is free. Disputes about pre-existing damage months later are expensive.

The structural check:

Put a 4-foot level on the floor in multiple spots:

• Does it rock? (floor not flat — self-leveling is needed)
• Any dips you can see light through? (major unevenness — self-leveling essential)
• Jump on a corner — does it flex? (deflection issue — structural concern)

If the floor flexes noticeably, tell the homeowner. A floor with L/360 or worse deflection will crack tile within a year regardless of everything else you do right. They may need a structural repair before tiling.

The Gotcha Items You Must Identify Before Pricing

These items look minor but represent hours of work. Miss them in the quote and you absorb them in the job.

Shower windows: Always a separate line item. $350–500 minimum. Waterproofing the sill, sloping for drainage, wrapping the jambs, cutting tile to fit three sides of a window opening — this is a 2–4 hour sub-project. Never bundle it into the wall rate.

Niches: Each niche requires layout, waterproofing, back wall tile, three sides of wrapped tile, a flat bullnose or mitered edge, and grouting of a complex interior. $250–350 each. Never included in the wall square footage rate.

Shower benches: $400–600 for a standard built-in bench with stone top. Structural blocking, waterproofing, tile on the bench face and sides, a stone or tile cap, edge treatment. Its own line item.

Curb construction: The shower curb is its own phase — form it from mortar or Kerdi foam block, waterproof it, tile the top and both sides. $300–450.

Second-floor premium: Working on a second floor means carrying materials up stairs, more careful debris management, longer setup time, and more risk if there's a leak during water testing. Add 10–20% to your total for any second-floor job in an occupied home.

Self-leveling underlayment: If the floor check reveals the floor needs leveling, this is never bundled into the tile rate. It's a separate line item with its own material cost and labor. More on self-leveling as an upsell, not a cost.

Occupied home logistics: Tools have to come in, tile has to come in, demo debris has to go out — all without destroying a lived-in house. Factor this into your time estimate. It's real.

How to Structure the Estimate: Zone-Based Pricing

The most common quoting mistake is treating the bathroom as one price per square foot. Every zone in the bathroom has different complexity, different production rates, and different risk. You need different line items for each.

Zones within the bathroom:

• Floor
• Shower pan
• Shower walls
• Vanity backsplash
• Details (niches, benches, window wraps, curb)

Phases within each zone:

• Demo
• Prep / self-leveling
• Waterproofing
• Backer board
• Tile installation
• Grouting

Every phase gets its own line with its own price.

Typical line items for a standard bathroom

Demolition phase:

• Demo existing floor tile: X sq ft × $X/sq ft
• Demo existing shower walls: X sq ft × $X/sq ft
• Demo existing shower pan: $X flat
• Debris removal and disposal: $X flat

Floor zone:

• Floor prep / grinding: X sq ft × $X/sq ft
• Self-leveling underlayment: X sq ft × $X/sq ft
• Anti-fracture membrane: X sq ft × $X/sq ft
• Floor tile installation: X sq ft × $X/sq ft
• Floor grouting: X sq ft × $X/sq ft

Shower pan zone:

• Preslope: $X flat (if traditional dry pack)
• Waterproofing (prefab Kerdi or liquid-applied): $X
• Top mud bed (if traditional): $X flat
• Shower pan tile installation: X sq ft × $X/sq ft
• Shower pan grouting: X sq ft × $X/sq ft

Shower walls zone:

• Cement/Kerdi backer board installation: X sq ft × $X/sq ft
• Waterproofing walls: X sq ft × $X/sq ft
• Shower wall tile installation: X sq ft × $X/sq ft
• Shower wall grouting: X sq ft × $X/sq ft

Backsplash zone:

• Backsplash tile installation: X sq ft × $X/sq ft (price higher than walls — backsplashes are slow)
• Backsplash grouting: X sq ft × $X/sq ft

Details:

• Niche(s): $X each
• Bench: $X flat
• Shower window wrap: $X flat
• Curb construction and tile: $X flat

Why this structure protects your margin

When the homeowner says "can we add another niche?" mid-job, you have a clear $275 price for that niche — not a guess. You write a Change Order with a specific dollar amount.

When they want to compare your quote to another installer's, they can line-item compare. Comparing your $9,100 transparent breakdown to a $7,500 lump sum usually ends with the homeowner choosing you.

The Real-World Primary Bath Example

Here's an actual bathroom I quoted and completed last year. I'm using baseline pricing built from a percentage system anchored to my floor install rate.

Job specs:

• 65 sq ft floor in 12×24 porcelain, straight lay
• 100 sq ft shower walls in 4×12 subway tile
• 20 sq ft shower pan in 2×2 porcelain mosaic (Kerdi system)
• 15 sq ft vanity backsplash in same 4×12 subway tile
• 2 niches, 1 built-in bench, 1 shower window
• Second-floor bathroom, occupied home
• Homeowner providing all tile
• My baseline: $8/sq ft for straight lay floor

The estimate I delivered:

Line Item	Amount
Demo existing floor tile (65 sq ft × $4)	$260
Demo existing shower walls (100 sq ft × $4)	$400
Demo existing shower pan (flat)	$350
Debris removal and disposal	$150
Floor prep and grinding (65 sq ft × $2)	$130
Self-leveling underlayment (65 sq ft × $4)	$260
Anti-fracture membrane (65 sq ft × $2)	$130
Floor tile install, straight lay 12×24 (65 sq ft × $8)	$520
Floor grouting (65 sq ft × $1.50)	$98
Kerdi shower pan with prefab foam base	$1,200
Shower pan tile install, 2×2 mosaic (20 sq ft × $13)	$260
Shower pan epoxy grout	$200
Kerdi-Board backer on shower walls (100 sq ft × $7)	$700
Shower wall tile install, 4×12 subway (100 sq ft × $11)	$1,100
Shower wall grouting (100 sq ft × $1.65)	$165
Backsplash tile install (15 sq ft × $14)	$210
Backsplash grouting (15 sq ft × $1.50)	$23
Niche #1	$275
Niche #2	$275
Built-in bench with stone top	$500
Shower window wrap	$450
Curb construction and tile	$350
Subtotal	$7,906
Second-floor premium (15%)	$1,186
Total	$9,100

The job took 9 working days across 12 calendar days. Finished on budget. Homeowner gave me a 5-star review and has referred me to two neighbors.

The homeowner requested a 3rd niche mid-job — I added it as a $275 Change Order without re-quoting anything. The line-item structure made that frictionless.

Common Bathroom Quoting Mistakes

These fit squarely in the category of common tile contractor business mistakes — but bathrooms amplify each one because the scope is larger.

Quoting a price per square foot for the whole bathroom. The floor, walls, and shower pan are different jobs with different production rates. A single blended rate either overprices the simple parts or underprices the complex parts.

Forgetting the second-floor premium. If you're working on a second floor in an occupied home, add 10–20%. The extra logistics are real and they take time.

Bundling niches, benches, and window wraps into the wall rate. These are separate line items. Always.

Skipping the self-leveling check. If the floor needs leveling and you didn't quote it, you're either doing it for free or having an uncomfortable conversation mid-job. Check the floor with a level during your walkthrough, every time.

Ordering 10% waste for herringbone or diagonal patterns. Order 20–25% for complex patterns. If the homeowner orders 10% based on what a supplier told them, put your 25% recommendation in writing.

Using the same tile rate for the backsplash as the shower walls. Backsplashes are slower — outlets, faucet cutouts, precise cuts around the vanity mirror, intricate layout in a tight space. Price them 20–30% higher than shower walls.

Not documenting pre-existing damage. Your photos from the walkthrough are evidence. If there's a crack in the subfloor, water staining behind the existing tile, or structural flex — document it and note it in the estimate.

The Terms That Go On Every Bathroom Estimate

Your estimate isn't just prices. The terms section is what protects your business.

Payment schedule:

• 50% deposit on signing
• 25% progress payment after shower pan water test passes
• 25% final payment on completion, collected before you leave

Scope change clause: "Any changes to the scope of work after signing will be documented as a written Change Order with adjusted pricing. Change Orders must be signed by both parties before work begins."

Tile responsibility: "Client is responsible for providing all tile material, including specialty pieces and 20–25% extra for waste (25% for herringbone, diagonal, or other complex patterns)."

Material inclusions/exclusions: "Price includes all installation materials (thinset, grout, waterproofing, backer board, fasteners, spacers, leveling clips). Tile, stone, fixtures, and specialty trim pieces are supplied by client unless otherwise noted."

Access requirement: "Job requires clear access to the bathroom and adjacent areas for the full duration of the project. Client is responsible for removing personal items from the bathroom prior to start date."

Debris removal scope: "Price includes removal of demo debris from the work area. Homeowner is responsible for removing all furniture and fixtures from adjacent areas prior to start."

Delivering and Following Up

Deliver the estimate within 24 hours of the walkthrough. Longer waits tell the homeowner you're not responsive — which makes them hire the faster-responding (usually cheaper, less experienced) installer.

Your estimate document needs:

• Your business name, logo, and contact info at the top
• Client name and job address
• Estimate number and date
• Full line-item breakdown
• Subtotal, adjustments, total
• All terms and conditions
• A signature line with space for date

Follow up in 48–72 hours if you haven't heard back: "Hi [homeowner], just wanted to follow up on the estimate I sent for your bathroom project. Any questions I can answer?" Professional, not pushy.

Automating the Estimate Process

Building a full bathroom estimate from scratch takes 45–60 minutes even after a clean walkthrough — calculating each zone, applying pattern multipliers, adding premiums, formatting the document, checking that every line item is included.

TileForeman does this in a few minutes. You enter the zone measurements, select patterns, toggle in details (niches, bench, window), and the app builds the itemized estimate with your rates and all the line items — formatted and ready to send. The payment schedule, scope change language, and tile responsibility terms are built in as default. Free during beta.

Wrapping Up

A bathroom quote is a 45-minute walkthrough translated into a document that protects your business and tells the homeowner exactly what they're getting.

Ask the right questions before you measure. Check the floor structurally. Photograph everything. Price every zone separately. Pull the gotcha items — windows, niches, benches, second-floor premium — into their own line items before you send the estimate. Deliver within 24 hours. Follow up in 72.

The installers who do this consistently get more referrals, fewer scope disputes, and more signed estimates at their real price.
