How to Quote a Tile Shower From Substrate to Finish

A shower can look ready for tile while damaged board, crooked framing, and a bad drain connection remain hidden. Knowing how to quote a tile shower means pricing what you can inspect and setting a clear release point for what you cannot.

Do not bury those unknowns inside a square-foot rate. Define the shower, inspect it, measure every tiled face, and price each operation.

Set the shower scope before taking measurements

Decide what you are being asked to build. The phrase “tile the shower” is not a scope.

Walk the customer through the finished assembly. Record the shower walls, floor, curb, niche, bench, jambs, returns, shelves, exposed edges, and transitions into the bathroom. Note which existing parts stay and which come out.

Price the post-demolition inspection and each required hold-point release visit. State whether the quote includes the labor and travel for those visits.

Assign supply responsibility next. State who supplies the field tile, shower-floor tile, trim, grout, sealant, drain, fixtures, accessories, and waterproofing components. Do the same for plumbing and glass work.

Customer-supplied tile is not contractor-controlled material. Write down who checks the quantity, shade, damage, dimensions, compatibility, and delivery date. State that missing, unsuitable, or damaged material can affect the schedule and may require a priced change order.

Separate allowances from exclusions. An allowance leaves a named item unresolved, such as a tile selection that has not been made. An exclusion keeps work outside your price, such as drain relocation by a plumbing contractor.

Inspect visible conditions and stop at the demolition gate

Photograph the complete shower before pricing it. Then take close views of cracks, movement, staining, damaged finishes, exposed edges, penetrations, and the visible drain area.

Record access through the property. Note stairs, parking, floor protection, dust control, working-hour restrictions, debris handling, and whether another contractor will be working in the room.

Inspect what is exposed without pretending you can see through the finish. Check visible walls for flatness and plumb. Look at outside corners, jambs, fixture positions, and transitions into adjoining floors and walls. Record any sign that the existing assembly has moved or taken on moisture.

The old surround may still be in place. You cannot confirm whether the framing is flat, plumb, sound, or properly backed. Say that in the quote.

Set a demolition limit and a substrate hold point. For example, the fixed work may include removal through the existing board, followed by an inspection before framing correction or concealed repair starts.

Keep tiling preparation costs specific. Use lines such as demolition, framing correction, backing, board installation, flattening, patching, cleaning, and priming. “Normal preparation included” tells the crew and customer nothing.

State the preparation limit you have priced. Work beyond that limit waits for photographs, a written description, a cost, and customer approval. The crew does not cover concealed damage and argue about it later.

Take off every tiled face as a separate line

Measure the shower as a group of planes and details. Wall area alone misses much of the work.

Create separate takeoff lines for:

• Each wall.
• The shower floor.
• Each curb face and the curb top.
• Niche backs, sides, tops, and sills.
• Bench tops, faces, and sides.
• Door jambs and returns.
• Shelves and ledges.
• Exposed edges and transitions.

Measure each rectangular face as length × width. For a curb, record the top, inside face, outside face, and ends separately. For a niche, record the back, sill, top, and sides. Measure jambs and returns as narrow faces, not as part of the main wall.

Keep the shower floor apart from the walls. It may use a different tile, purchase unit, layout, slope, and drain detail.

Record the actual product, not a loose description. Capture the tile dimensions, thickness, orientation, pattern, face variation, edge condition, and purchase unit. A nominal size does not tell you how the pieces will align around the niche or drain.

Mark every valve, shower arm, drain, accessory, and glass position. Record the intended start lines and feature alignment. A penetration removes little area but adds drilling, cutting, waterproofing, and layout work.

Group only faces that use the same product. Add those face quantities to form a product subtotal. Subtract an opening only when the omitted surface creates a real saving and no tiled return, edge, or small face replaces it.

A niche removes field tile from a wall, then adds several small faces, corners, cuts, waterproofing transitions, and finished edges. Less net wall area can create more work.

Convert each product subtotal into the units that can actually be purchased. Keep field tile, mosaics, trim pieces, and sheets on separate lines. Use the supplier’s current coverage per piece, sheet, or box, then round up to a complete purchase unit.

Set the tile wastage allowance from the chosen layout

A tile wastage allowance is a purchasing decision. It is not a standard percentage copied from the last shower.

Lay out the selected product on paper or in your job sketch. Consider centered layouts, edge cuts, directional faces, veining, pattern matching, fragile pieces, shade consistency, and any spare material the customer wants after completion.

Calculate the order as measured product quantity + layout and cut allowance + agreed handover stock. Convert the result to the supplier’s purchase unit and round up to complete pieces, sheets, or boxes. Record whether usable offcuts can carry into another face; directional or matched tile may prevent that reuse.

Do not use waste to cover bad measurement. Show the measured requirement, the layout adjustment, the handover stock if requested, and the final purchase quantity.

If the customer has not selected the tile, do not pretend the quantity and setting labor are settled. Carry a clearly named allowance or issue an estimate for the unresolved part. Convert it to a fixed quote after the product, layout, edge finish, and purchase units are confirmed.

Write the waterproofing boundary before costing it

Tile is the finish. It does not tell you whether the assembly behind it controls water.

The waterproofing quote scope must identify the selected assembly and components; included surfaces; seams, corners, penetrations, and drain transition; preparation; required hold points; testing responsibility; and the installation instructions the crew will follow.

State the required starting condition for the framing, backing, substrate, shower base, and drain.

Define the plumbing handoff. State who supplies the drain, who connects it, who relocates it if required, and what must be complete before your work continues. Do not include regulated plumbing work until you confirm who is licensed to do it, who prices it, and where your tile scope stops.

Record any required waiting period, return visit, test, inspection, or hold point without inventing a local rule. Show who books it and whether the crew can complete another operation while waiting.

Glass needs the same treatment. State who provides blocking, who confirms the finished opening, who measures for glass, and which penetrations or mounting areas affect the waterproofed assembly. Do not let the glass installer arrive expecting backing that nobody agreed to install.

Who gets the next call on a U.S. shower job?

One approval does not cover every trade, permit, and license question. Call the office that answers each question.

Use the official state government directory (opens in a new tab) and official local government directory (opens in a new tab) to identify the contractor-licensing authority with jurisdiction over the job. Ask that authority whether a contractor license is required for the planned scope and which classification applies, if any, then write down the answer.

If the job includes drain relocation or another regulated plumbing task, use those official directories to identify the state or city plumbing licensing office with jurisdiction. Ask which plumbing license covers that work, then assign the work or limit your scope based on the answer.

Ask the local building department (opens in a new tab) whether the planned work needs a permit, inspection, test, or hold point. Record who applies, who pays, who provides access, and what must be approved before the next layer covers the work.

Keep the answers separate. A building permit does not answer a contractor-license question. A contractor license does not settle who may perform plumbing work.

How to quote a tile shower with labor and material pricing

There is no reliable shower price before inspection and tile selection. A broad area rate cannot see substrate damage, layout, niches, access, drain work, or glass handoffs.

Estimate labor by operation. Build labor lines for protection, demolition, debris handling, post-demolition inspection, preparation, waterproofing, layout, cutting, drilling, setting, edge finishing, grouting, sealant, cleaning, and punch-list corrections.

Use crew-hours. Start with the measured planes and details. Adjust for access, cuts, penetrations, edges, material handling, and hold-point visits. Compare each operation with records from completed jobs, total the worker-hours, then multiply them by your loaded labor cost. Loaded cost comes from your own payroll and employment costs. It is not the wage paid to the installer.

Price materials from the completed takeoff. Include setting and waterproofing components, trims, consumables, protection, disposal, and delivery where they are direct job costs. Use current supplier costs rather than memory.

Add confirmed subcontractor prices and other direct costs. Then account for overhead and apply markup to produce the selling price. The contractor labor and material pricing framework explains how those buckets fit together.

Keep this costing worksheet internal:

Markup is what you add to cost to reach a selling price. Margin is profit as a share of that selling price. Do not use the terms as if they mean the same thing.

Keep unresolved allowances visible. Exclude work that has not been inspected, selected, or assigned. A clear gap is safer than a hidden guess.

Write a quote the installer can follow

The quote should work as the source document for the job. A crew member should be able to identify the included surfaces, selected materials, layout, preparation limit, waterproofing boundary, edge treatment, and trade handoffs without asking what was sold.

Use this blank structure when deciding how to write a quote:

Customer and site: [name and address]
Quote number and date: [details]

Existing condition:
[visible finishes, access, movement or moisture signs]

Demolition limit:
[exact materials and surfaces to be removed]

Post-demolition hold point:
[what will be inspected before concealed work continues]

Included substrate preparation:
[named operations and limits]

Waterproofing boundary:
[included surfaces, penetrations, transitions, and drain handoff]

Tile schedule:
[product, purchase unit, direction, pattern, grout, trim, and sealant]

Tiled surfaces:
[walls, floor, curb, niche, bench, jambs, returns, and shelves]

Supply responsibilities:
[contractor, customer, plumbing contractor, glass contractor]

Allowances:
[named unresolved item and reconciliation method]

Exclusions:
[work outside the quote]

Approvals and hold points:
[tile selection, layout, substrate findings, waterproofing, inspection]

Customer price:
[total selling price, priced options, and named allowances]

Change-order rule:
[extra or changed work requires written approval before it starts]

Acceptance:
[customer approval fields]

After acceptance, turn the quote into a site document. The contractor work-order guide shows how to carry the accepted scope into crew instructions without rewriting the deal from memory.

Stop and write a change order when the shower changes

Demolition is a release point. If it exposes damaged board, framing correction, missing backing, or a drain condition outside the quote, stop the affected work.

Photograph the condition. Describe the correction. Price the added labor, material, subcontractor work, and schedule effect. Get written approval before covering it.

Use the same process when the customer changes from a simple straight layout to directional or fragile tile, adds a niche, moves a drain, changes edge treatment, or asks for work on another surface. The accepted quote does not quietly stretch.

The house example is electrical, but the document control is the same. On the R. Chen job at 14 Oak Street, quote Q-1847 covered a bathroom exhaust fan and four LED downlights for 1,105 sample currency units. The ceiling was lined and chasing was excluded. Extra cable and chasing became an approved 160 change order, so invoice INV-1847 totaled 1,265.

The original-scope job cost was 850. Measured against the original quote, profit was 1,105 − 850 = 255. Margin was 255 ÷ 1,105, or about 23%, while markup was 255 ÷ 850, or 30%.

Do not calculate profit using the 1,265 invoice. The cost of the 160 change order is not given. These figures are a worked example in sample currency units, not a tile rate card.

After the shower closes, compare actual labor, material, subcontractor, and direct costs with the original scope. The finished-job costing process gives you a clean way to find the operation that ran over.

Knowing how to quote a tile shower is only useful if the accepted scope stays attached to the work. Yes Foreman can keep the accepted quote, site photos, work order, change orders, costs, and invoice attached to the same job.

Open your next shower lead now. Photograph the visible conditions, draw each tiled plane, and set the post-demolition hold point before you price the work.
