Deckari / bathroom planning tool

Estimate the cost of a bathroom remodel.

Build a rough installed-cost range based on bathroom size, remodel scope, finish level, plumbing changes, shower or tub choices, optional upgrades, and regional labor conditions.

Bathroom project details

Most estimates take about a minute to complete.

01 / Size & scope

Describe the basic project.

Start with approximate room size and the level of remodeling you have in mind.

A typical 5 × 8 bath is about 40 sq. ft.; larger primary baths are often 80–150+ sq. ft.
02 / Layout & wet area

How much construction changes?

Plumbing relocation and custom shower work are two of the biggest cost drivers.

03 / Materials & cabinetry

Choose the finish level.

Material selections affect the estimate, but labor and installation quality remain a large part of the total.

04 / Optional features

Add upgrades you are considering.

These are modeled as installed-cost allowances before the regional adjustment.

05 / Location

Adjust for regional cost conditions.

Enter a five-digit U.S. ZIP code. The calculator uses it only to apply a broad regional construction-cost factor.

Leave blank to use the national baseline. This ZIP adjustment is intentionally broad and is not a local contractor quote.

How the model works

Bathrooms cost more than their square footage suggests.

A bathroom concentrates expensive trades and materials into a small room: plumbing, electrical, waterproofing, tile, cabinetry, countertops, glass, fixtures, ventilation, demolition, and finish work. That is why a simple per-square-foot number can be misleading.

This estimator starts with a modeled national baseline, then changes it according to project scope and regional cost conditions. The result is deliberately presented as a range rather than a promise.

01

Scope before square footage

A 45-square-foot full gut remodel can cost more than a larger cosmetic refresh because the expensive systems and fixtures are still concentrated in the room.

02

Plumbing and layout changes

Keeping drains and supply lines near their current locations is usually less expensive than relocating toilets, showers, tubs, or vanities.

03

Wet-area complexity

Custom walk-in or curbless showers require more waterproofing, tile labor, drainage work, glass, and detail coordination than a straightforward replacement.

04

Regional labor conditions

ZIP is used for a broad regional multiplier. High-cost markets such as Los Angeles, San Francisco, New York, Seattle, and Hawaii are modeled above the national baseline.

How to use the result

Use the estimate to plan, compare, and ask better questions.

The most useful number is not the exact midpoint. It is the budget band and which choices move that band up or down.

01 / Compare

Try different scopes.

Compare same-layout vs. major-layout changes, a standard shower vs. curbless, or mid-range vs. upscale finishes.

02 / Allow

Keep room for surprises.

Older bathrooms can reveal damaged framing, outdated wiring, plumbing problems, or waterproofing failures once demolition begins.

03 / Verify

Get the actual property priced.

A contractor can evaluate the room, access, existing systems, code requirements, material selections, and final construction scope.
