Bathroom Design & Finish Planner
Explore a coordinated look, choose what you are actually changing and carry verified floor dimensions into the separate tile-quantity tool below. This is a conceptual finish preview, not a photographed room, a scaled layout or a construction plan.
Warm stone, oak-look cabinetry and a relaxed tonal palette.
Select finishes, then build a checklist of your design decisions.
Your design decisions
What to verify before installation
Important design limitations
The design controls only change illustrative finishes and measured floor dimensions. Floor and shower tile quantities must be checked separately.
Planning example, not a purchase recommendation. The preview never claims that a double vanity, walk-in shower or tub fits the measured room. Layout, door clearance, ventilation, accessibility, waterproofing and local approvals must be checked from real drawings and site conditions.
Photo-Assisted Wall & Floor Finish Preview
Select a photo from your device, try a guided wall/floor outline or mark the surface manually, then test a finish while retaining its existing light and shadow. The photo stays inside your browser: no account, upload, tracking endpoint or AI service is used.
An illustrative 2D mockup, not a photorealistic AI render, real product sample or measured installation plan.
What can this preview show—and what can't it?
Guided selection follows similar photographed colors: its soft mask may protect contrasting fixtures, but objects of a similar color can still be included. Four-corner patterns only approximate perspective. Check surfaces and real dimensions before buying materials or asking a contractor to install them.
Choose Wall or Floor, press the button, then tap a clear part of the surface in your photo. Drag the blue corners to refine the suggested area.
How do the outline, tolerance and mask work?
Lower tolerance matches fewer shades; higher tolerance includes more. The private, color-based helper proposes four corners and a soft mask, not true object recognition. For busy photos, manually mark the surface, enable the object-protection brush and exclude fixtures before applying.
Guided masks start from connected photo colors. Manual masks start with the whole outlined surface and let you protect fixtures with a brush. Turning this off applies the finish across the full outline.
After marking at least three points, add a local mask. Use Protect to exclude furniture, mirrors or fittings—even if their color matches the wall.
Protect removes finish from an object; Restore adds missed surface pixels. Draw directly on your photo.
Brush tips and how to undo corrections
A fixture matching the wall color may be included by mistake. You can undo or redo eight steps, reset corrections, and return to Edit corners to adjust the boundary. Restoring cannot paint outside the outline. Your original photo pixels are never changed.
Left: your selected finish. Right: the unedited original. The downloaded PNG always contains the complete edited result.
3. If using manual mode, tap or click around one visible surface in order (at least three points), or refine the guided four corners by dragging blue handles. The sample room supports instant presets without this step. Numeric fields also work with a keyboard; each point is a percentage of photo width/height.
0 boundary points
4. Your applied finishes
Select a finish to restyle, refine its outline or remove it without changing other surfaces.
How to edit a saved finish safely
Selecting a finish restores its color, pattern and visual settings. To change the shape or protect an object, choose Adjust selected outline, move the blue points or use the mask brush, then save. Cancel keeps the saved version intact.
The preview shows all applied finishes.
Inspection affects only the on-screen editor. Exports, your saved project and the contractor brief always retain every applied finish.
What can the finish history recover?
Undo/redo remembers up to eight applied finish changes in this tab, including removals and clearing all finishes. Draft points and mask brush strokes have separate controls. Opening a different photo or saved project starts a new history; history is not embedded in the downloaded project.
Single PNG export keeps your photo's proportions and detail up to 2400 pixels on its longer side. The labeled before/after PNG places two equal-scale views side by side, with each panel capped at 1200 × 1800 pixels for easy sharing.
Save or reopen an editable room project
A saved .json project includes a copy of your original photo, its surface outlines and masks, finish settings and notes. Keep this personal file private. Nothing is uploaded or saved to an account. Save only after applying finishes; unfinished draft points are not included.
What goes into the brief? How is my photo kept private?
The text brief lists visual finishes, installation questions and comparison items; it does not include your photo or calculate room dimensions. Share the PNG separately if you want. Only a successfully loaded new photo resets your finishes (your notes are retained); invalid files leave the current project intact. “Remove photo, finishes & notes” clears this local editor.
Choose your photo or try the sample to begin. No file is transmitted.
Blue handles, teal mask and selection outlines are editing guides, never part of the exported PNG. Check edges around fixtures before downloading.
Review your design and measure surfaces
Suggested quantity step for your selected finish: Interior Material Calculators. Measure the real wall or floor and check manufacturer coverage details; the photograph supplies neither dimensions nor a product specification.
Use the Bathroom Design & Finish Planner with verified room measurements. Do not infer square footage, installation details or waterproofing requirements from the photograph.

Trace a full bathroom tile budget
A detailed 40 sq ft illustrative scenario separates floor and shower tile, package rounding, fixture allowances and quoted labor. It is an educational case with transparent, hypothetical amounts, not a claim about local market rates or site suitability.
Plan floor tile and shower-wall tile separately
Measure the room floor independently from the tiled shower walls. Use the actual packaging coverage for each tile product to calculate whole cartons; do not combine cartons from different tile systems or assume they are interchangeable.
Your separate tile takeoffs
Only the net floor area is transferred to the cost estimator's floor-area basis. Shower-wall tile, waterproofing, fixtures and licensed work require separate actual supplier or contractor allowances; do not pretend their cost scales with bathroom floor area.
Continue your project estimate
Estimate tile quantity →Use allowances instead of pretending every bathroom costs the same
Bathroom remodel budgets vary sharply with fixtures, tile, plumbing scope, demolition and labor. Treat the calculator as a transparent allowance model and replace each rate with a project-specific quote where possible.
Use related tile, paint or flooring calculators when you need a measured material quantity before assigning cost.
- Separate finish allowances from labor.
- Keep contingency visible rather than hidden.
- Update the estimate as selections become known.
From finish inspiration to an actionable bathroom plan
Use the design planner to compare a warm spa look, a modern high-contrast bathroom or a softer green-and-wood palette. Changing the proposed vanity or shower changes your planning checklist, not a hidden estimate. A decorative drawing cannot confirm that your chosen fixtures fit, and a style label cannot determine a local contractor price.
Once the concept is clear, transfer the actual room dimensions into the tile takeoff. Floor tile and wet-area wall tile are different materials, so they must have their own coverage and extra allowance. Next, use the cost form with your supplier and installer prices. The design tool will never fill in fabricated rates or automatically add unquoted work to your budget.
A cosmetic refresh often preserves plumbing locations and existing surfaces, while replacing fixtures or rebuilding a shower can introduce removal, waterproofing, ventilation and licensed-trade considerations. This is a scope comparison, not a promise that a project is cheap, permitted or physically possible. Verify site conditions and professional requirements before ordering.
Choose bathroom finishes for the room you actually have
The three visual styles in the planner are starting palettes, not products or construction specifications. Before choosing a tile or vanity, bring actual samples into the room and inspect them under daytime and evening lighting. A preview on a phone cannot reproduce the scale, texture, gloss or color of installed materials.
| Design choice | Visual effect | What changes in the real project |
|---|---|---|
| Offset rectangular wall tile | Repeated grout joints and a more detailed wall pattern | Ask for the actual tile dimensions, pattern offset, grout width, substrate suitability and installer cutting allowance |
| Large-format wall tile | Fewer visible joints on many layouts | Check wall flatness, handling, edge cuts and any additional substrate preparation; fewer joints do not make an installation automatically waterproof |
| Vertical stacked wall tile | Strong vertical lines and a different sense of proportion | Confirm tile orientation is approved, joint alignment around niches and corners, and where cut pieces land |
| Stone-look or wood-look porcelain floor | Natural-material appearance without assuming natural stone or real wood | Verify the exact product's wet-floor slip performance, cleaning instructions, shade variation, grout and substrate requirements |
| Single versus double vanity | Different storage and counter arrangements | Measure actual cabinet width, door and drawer swings, circulation and plumbing; floor area alone cannot prove a double vanity fits |
| Keeping a tub versus considering a walk-in shower | A different wet-area look and daily use | Check drainage, required slopes, entry clearance, waterproofing, accessibility, demolition and plumbing with qualified trades |
For the same 8 × 7 ft (56 sq ft) room used in the tile example below, switching from an offset wall pattern to a large-format wall tile does not change the measured floor area. It can, however, change the tile SKU, carton coverage, cutting layout, labor quotation and suitability for the shower walls. Therefore, keep the design choice separate from the exact product measurements and quoted unit prices.
Compare remodel scopes before comparing contractor prices
A refresh, a finishes replacement and a full remodel can share the same mood board but have different work and risks. Record what stays and what changes before deciding which quote is less expensive.
| Scope | Typical planning question | Quotes and checks to request |
|---|---|---|
| Cosmetic refresh | Can sound existing surfaces and fixture locations remain? | Written paint and finish preparation, fittings, ventilation checks and any separately quoted repairs |
| Surfaces and fixtures | Which floor or shower finishes, vanity and fittings are actually being replaced? | Separate tile cartons, removal, substrate preparation, waterproofing scope, fixture supply and installation |
| Full remodel | Are layout or plumbing/electrical locations changing? | Site survey, qualified trade scopes, demolition, ventilation, approvals, schedule, access and explicit contingencies |
Buying sequence: agree on a scope → measure each surface → choose manufacturer-verified products → obtain comparable written quotes → enter actual material/labor rates into the calculator → carry one selected project estimate into Project Budget. Never add both competing contractor bids or duplicate tile material within a bundled rate and a fixed extra.
How this estimate works
Enter floor area and any per-square-foot material or labor allowances you want to compare. Use fixed extras for fixtures, plumbing, electrical, permits, cabinetry or other quoted items.
total = adjusted material quantity × material rate + project quantity × labor rate + fixed extras
Example
A 60 sq ft bathroom with $80/sq ft in material allowance and $100/sq ft in labor starts at $4,800 material and $6,000 labor before fixed items. Example rates are illustrative only; replace them with supplier or contractor pricing for your project.
Build the bathroom budget from separate scope items
A floor-area allowance is only a planning shortcut. Use the measurement tool above to take off floor tile and shower-wall tile independently. For a complete budget, keep fixture packages, tile, plumbing, electrical, demolition, cabinetry, waterproofing and permits visible as separate quote or allowance items. Do not also charge the same floor materials in both the square-foot rate and fixed extras.
Use the Tile Calculator for measured tile quantity and the Paint Calculator for finish-paint quantity before assigning local prices. Add the completed bathroom estimate to the Project Budget Workspace when it is part of a larger project.
This calculator does not decide code, waterproofing, ventilation, structural or licensed-trade requirements. Those depend on the actual project and local rules.
Worked example: bathroom floor and shower are different tile purchases
Suppose your bathroom floor measures 8 × 7 ft. The measured floor is 56 sq ft. With a chosen 10% extra for cuts, you need to cover 61.6 sq ft. If the floor tile you select actually covers 12 sq ft per carton, round 61.6 ÷ 12 upward to 6 floor tile cartons.
Now consider a tiled shower-wall section with a combined 5 ft horizontal wall run and 7 ft tiled height, minus 3 sq ft of untiled openings. The wall tile area is 5 × 7 − 3 = 32 sq ft. With its own 15% cutting allowance, plan for 36.8 sq ft of shower wall tile. If that different wall tile product covers 10 sq ft per carton, you need 4 wall tile cartons.
These are illustrative measurement, cutting and packaging assumptions — not recommended waste rates, product coverage values or local prices. Keep the 6 floor cartons and 4 wall cartons separate; cartons from distinct tile products are not interchangeable. The room's 56 sq ft is still the floor-area basis for the general budget form. Shower-wall labor, waterproofing and fixtures need their own project quotes.
How to avoid an incomplete bathroom quote
Ask every contractor for the scope in writing. Separate waterproofing and substrate preparation from decorative tile materials, confirm who supplies the vanity, toilet, shower components and ventilation, and identify removal, disposal, permit, electrical and plumbing work. Compare quote exclusions explicitly rather than assuming a low square-foot price covers the same work.
The measurement tool estimates a material quantity, not a compliant waterproofing assembly or a finished remodeling price. Professional waterproofing, drainage, electrical and plumbing decisions depend on the actual project and local rules. Use the side-by-side contractor quote comparison before choosing an installer.
Bathroom remodel scope checklist
Two bathrooms with the same floor area can have very different budgets. Before comparing scenarios, write down which of these scope groups are actually changing:
- Surfaces: floor tile, shower or tub surround, paint, trim and wall repair.
- Fixtures: vanity, countertop, sink, faucet, toilet, tub, shower hardware, mirror and accessories.
- Trade work: plumbing, electrical, ventilation, waterproofing and any required licensed work.
- Project extras: demolition, disposal, delivery, permits, floor or wall preparation and contingency.
Use the square-foot fields only for costs that genuinely scale with area. Put quoted fixture packages and one-time scope items into fixed extras, or keep them as separate line items in the Project Budget Workspace when you need a more auditable breakdown.
