Bathroom estimator tools & features
One page hosts the whole toolchain — the flagship bathroom remodel estimator plus every feature folded inside it. This directory organizes those features by the questions they answer: sizing the room, sharpening the numbers, pricing the complexity, and getting the result into a bid meeting. All free, all in-browser, all storing nothing on our servers.
The Bathroom Remodel Estimator
Left side: your room. Right side: the money. The estimator prices your exact square footage across four scopes and three finish tiers, applies your regional labor reality, itemizes the labor into eight named trades, and splits materials into tile, fixtures and paint — with a 10% contingency and every toggle's price shown on the toggle itself.
It is deliberately opinionated about transparency. There is no lump sum anywhere in the output: labor, materials, permits, contingency and each complexity adder are separate, named figures. Switch to Partial DIY and watch itemized trades leave the stack; print the quote sheet and hand it to three contractors unchanged; encode the whole configuration into a URL and reopen it on any device.

🛁Scope & size engine
Turn a room into an estimate range: four scopes, an exact-size slider, three finish tiers and three regional multipliers.
The core of the site is a single estimation engine, and it starts with the two inputs that decide more than everything else combined: how big the room is, and how much of it changes. The size slider runs from 20 to 250 square feet with presets at the classic sizes — 35 sq ft powder room, 60 sq ft hall bath, 100 sq ft primary bath, 140 sq ft luxury primary — but nothing forces your room into those buckets. A 65-square-foot bath is priced as 65 square feet, and the per-square-foot figure recalculates live as you drag.
Scope is the multiplier that resets the entire budget. Refresh (paint, vanity, fixtures, mirror — surfaces only) runs about half of a pull-and-replace budget. Pull & Replace swaps everything within the same footprint. Tub-to-Shower removes the tub and builds a tiled walk-in shower in its place while the rest of the room stands. Full Gut opens the walls — down to studs, new wiring, re-piped plumbing, re-waterproofed wet areas — at roughly 1.6× the pull-and-replace rate. Each scope carries its own labor share, which is what makes the later DIY math possible at all.
Finish tier and region apply on top of scope. Budget finish prices stock vanities and big-box fixtures at about 72% of mid-range; high-end prices custom cabinetry, stone and premium fixtures at about 155%. The regional multiplier scales the whole labor stack — 0.88× in lower-cost metros, 1.3× in high-cost coastal markets — because the same tile setter bills very different hourly rates in the Midwest and the Bay Area. Every multiplier is fixed and printed, so comparing scenarios is arithmetic you can verify, not faith you must extend.
Exact-size slider (20–250 sq ft)
Wall-to-wall square footage priced precisely, with live cost-per-sq-ft and one-click presets at 35 / 60 / 100 / 140.
Four scopes, same inputs
Refresh, Pull & Replace, Tub-to-Shower and Full Gut — priced from identical inputs so scope comparison takes seconds, not re-quotes.
Finish tiers
Budget, mid-range and high-end multipliers covering the vanity, tile, valve and fixture-grade decisions that swing the same room by 2×.
Regional multipliers
Lower-cost, national-average and high-cost metro tiers applied to the entire labor stack — not just one convenient line of the bid.
📐Precision & dimension tools
The advanced panel where a generic estimate becomes your room: shower and floor tile areas, vanity width, countertop material.
Headline estimates treat a bathroom as an area. Real quotes treat it as surfaces: so many square feet of shower surround, so many of floor, a countertop of a specific width in a specific material. The advanced dimensions panel — collapsed by default to keep the first screen clean — accepts those real inputs and lets the engine price materials the way a supplier will.
Wet-area math matters most. The shower surround area drives wall tile quantity, and wall tile carries a 15% cut-and-waste factor because niches, valves and bench framing generate offcuts that a straight floor field never will. Floor tile gets the standard 10%. The paint line is calculated honestly too: tile area is netted out of paintable wall area, so you don't buy gallons that never get opened. These derived areas update automatically from your total square footage when you leave them alone — set them manually when your room doesn't fit the ratio.
Countertop pricing works the same way a fabricator quotes it: vanity width in inches times the standard 22-inch depth, times the installed rate for the material you pick — laminate, quartz, granite or marble, each with its own per-square-foot range. A 60-inch quartz top and a 36-inch laminate top are different line items with different economics, and the tool prices both the moment you change the width dropdown.
Shower & floor area inputs
Manual override of the derived wet-area split, for rooms where the standard ratio doesn't fit — with waste factors applied per surface.
Paint-aware tile math
Tile area is netted out of the paintable wall area automatically, so materials lists don't double-count the same wall twice.
Countertop material pricing
Laminate, quartz, granite and marble installed rates × your vanity width — priced the way a fabricator would quote it.
Derived materials list
Every dimension you set flows into a line-item materials list — quantities as they should be ordered, waste included.
⚙️Complexity & plumbing toggles
Seven priced upgrade toggles, three plumbing scenarios, a pre-1980 risk buffer — each showing its own dollar range before you commit it.
Bathroom budgets rarely fail on the base scope; they fail on the decisions that hide inside it. This tool makes every decision a named, priced line. Heated tile floors, curbless showers, freestanding tubs, custom vanities, steam systems, electrical rough-in scope, and plumbing relocation each carry a fixed dollar range displayed on the toggle itself — turn it on and you see exactly what it adds, turn it off and it's gone from the total. No checkbox changes the number by a hidden amount.
Plumbing scope gets its own three-level selector because moving drains is a logistics project, not just labor. Cosmetic Refresh swaps fixtures in place at zero plumbing adder. Partial Reconfiguration — moving the toilet or vanity a few feet — adds plumber labor plus permit fees plus dumpster costs, because relocated drains mean opened subfloor and a municipal inspection. Full Gut-to-Studs assumes re-piping the room, a new vent stack and re-waterproofing, and prices all three. The distinction between these levels is the single most common source of bid disagreement, and the selector exists to end arguments about it.
Home age is the last toggle, and the least optional. Houses built before 1980 routinely hide galvanized supply lines, corroded cast-iron drains and particleboard subfloors that disintegrate the moment demo touches them. The pre-1980 toggle adds a $1,200–$2,500 rough-in and subfloor buffer — the same cushion experienced contractors quietly pad into older-home bids. Better to see it in your own estimate than to meet it later as a change order.
Seven priced upgrade toggles
Heated floor, curbless shower, freestanding tub, custom vanity, steam system, electrical scope, plumbing moves — each with its visible +$ range.
Three plumbing scenarios
Cosmetic in-place swap, partial reconfiguration (labor + permit + dumpster), or full gut-to-studs re-pipe — priced separately so bids become comparable.
Pre-1980 risk buffer
A $1,200–$2,500 adder for the rough-in and subfloor surprises older homes bury behind tile — visible contingency, not silent optimism.
Live visual breakdown
A donut chart re-splits labor, fixtures, tile and contingency the moment any toggle changes — you always see where the money went.
📤DIY mode & output tools
Strike the trades you self-perform, print a clean quote sheet, and carry your configuration anywhere via a link.
Labor is 45–55% of most bathroom remodel bills, and some of it is genuinely within reach of a careful homeowner. Flipping to Partial DIY checks tear-out and painting by default, and lets you add flooring, tile setting or fixture setting if those match your actual skill. The moment a trade is checked, its itemized labor dollars leave the estimate and the savings badge updates — the remaining professional work (plumbing rough-in, electrical, waterproofing) stays priced, because permitted code-bound stages don't belong on a weekend schedule no matter how confident the video tutorial sounded.
The printable quote sheet is the tool's most-used output. Enter an optional project name, click print, and the browser produces a clean A4 document with your configuration, the estimate range, the cost breakdown by category, labor by trade, the full materials list and the contingency recommendation — navigation, ads and input panels stripped automatically. Its real purpose is bid comparison: hand the identical sheet to three contractors and ask each to match or beat it line by line. Identical documents make scope differences between bids impossible to hide.
Everything else lives where you are. Saved estimates stay in your browser's local storage — nothing uploads, nothing syncs, and clearing them takes one click. Every calculation also encodes into the page URL, so the link you text to a partner or paste into a project note reopens with your exact inputs loaded on any device. For a planning session that spans weeks and several people, that portability is the difference between a decision and a memory.

A run through the toolchain: 100 sq ft primary bath, Full Gut
The tools are designed as one pass, not a quiz — six decision points from a bare room to a printed quote sheet, in about two minutes. This walkthrough follows a realistic full-gut primary bath in a coastal metro.
Set the room and the ambition
Slider to 100 sq ft (the 10×10 primary preset). Scope: Full Gut — the 1970s original needs re-piping and new circuits anyway, so Refresh was never realistic. The engine prices the gut base before a single toggle is touched.
Set finish and market
Mid-range finish (semi-custom vanity, quartz top, designer tile) and the high-cost metro multiplier — the coastal-market reality that scales the entire labor stack 1.3×, not just one line.
Declare the plumbing truth
Full Gut-to-Studs plumbing scope: re-piped room, new vent stack, re-waterproofed wet areas — plus permit and dumpster line items that vanish from casual quotes and never from this one.
Price the wish list honestly
Curbless walk-in shower and a heated tile floor toggled on, each showing its own range; the freestanding tub toggled off after seeing its price. Wishes become line items, and line items can be declined.
Declare the house's age
Pre-1980 toggle on — galvanized supply and soft subfloor are likely in this house, so the rough-in buffer belongs in the plan rather than in a future change order.
Test the DIY lever, then print
Partial DIY with tear-out and painting checked trims the labor stack by its itemized share. Satisfied, name the estimate 'Primary Bath — Plan A', print the quote sheet, and book three bid meetings with the same document in each hand.
Which tool answers which question
The six questions every remodeler eventually asks, and the feature built to answer each one.
| The question | The tool | How it answers |
|---|---|---|
| Which trades can I safely self-perform? | Partial DIY mode + labor-by-trade breakdown | The eight itemized trade lines each carry a DIY-eligibility flag; checked trades vanish from the labor stack with their dollar value shown. |
| Is moving the toilet worth it? | Plumbing scope selector (3 levels) | Partial Reconfiguration prices the plumber labor, permit fee and dumpster together — so the layout wish carries its real logistics cost. |
| What does a steam shower actually add? | Priced complexity toggles (7) | Each toggle displays its fixed +$ range on the control itself; nothing changes the total by a hidden amount. |
| How much tile should I order? | Derived materials list | Wet-area wall tile carries a 15% waste factor, floor tile 10% — quantities as they should be ordered, not raw room dimensions. |
| How do I compare three bids fairly? | Print / Export PDF quote sheet | An identical line-item document handed to every bidder — scope differences stop hiding inside lump sums. |
| Will my partner see the same numbers? | Shareable estimate links | The full configuration encodes into the URL and reopens identically on any device — no re-typing, no transcription errors. |
Tool questions, answered
Is this a different calculator from the one on the homepage?+
It's the same engine, organized. The homepage runs the full calculator with its cost matrices, regional tables and worked example around it; this page is the directory that explains what each part of the tool does and which problem it solves. Both lead to the same estimate — this page just maps the terrain first.
Do I need to fill in the advanced dimensions panel?+
No. The engine derives sensible shower, floor, vanity and countertop defaults from your square footage automatically. The panel exists for rooms that don't fit the standard ratios — a huge walk-in shower in a small bath, an unusually long double vanity — and for anyone who wants the materials list to match a fabricator's quote exactly.
What happens when I toggle something off?+
Its dollar range leaves the estimate completely — from the total, from the visual breakdown, and from the printed quote sheet. Nothing is averaged in behind the scenes, and nothing lingers: an off toggle is as if the feature was never discussed.
Why does the DIY badge only show savings for some trades?+
Because only some trades are realistically self-performable. Tear-out, painting, flooring, tile setting and fixture setting carry DIY-eligible flags; plumbing rough-in, electrical and waterproofing don't, because they're permitted, inspected, code-bound work. The badge refuses to fantasize about the trades that fail inspection.
Can I run two scenarios and compare them?+
Yes — that's what share links are for. Configure scenario A, copy the link, then configure scenario B and copy again. Open both links side by side and the comparison is exact: same engine, same assumptions, only the differences you chose.
Does anything here cost money or require an account?+
No. Every tool on this page is free, runs entirely in your browser, and requires no sign-up. Saved estimates and print jobs stay on your device, and the site's privacy policy documents exactly how little data exists to begin with.
