Plan your
bathroom addition.
Choose what you know. Get the questions that matter next. This planner organizes decisions; it does not approve a layout or estimate construction prices.
Your next conversation
Start with the unknowns.
Select the details on the left to create your brief.
- Identify a candidate location and desired fixtures.
- Have the drain route, structure and finished layout assessed.
- Confirm the actual permit authority and application scope.
- Compare proposals with the same inclusions and assumptions.

No account or automatic submission. Printing includes your notes. A contractor must assess feasibility and pricing.
Use your own figures
What is included
in your working total?
Add documented quote inputs. Blank fields count as zero in the sum, but missing costs remain unknown—not free.
Total of entered amounts
Base proposal + allowance overages + required excluded work + additional reserve.
This is arithmetic using your figures, not a contractor estimate, appraisal, financing recommendation or Kansas City market-price forecast.
How the planner makes its suggestions
The planner uses your selections to flag relevant questions. Basement projects surface moisture and drainage questions; exterior additions surface site, foundation and roof questions; bathing facilities surface floor-height and waterproofing questions. An unanswered input stays a question. No weighted score is used to claim your home is buildable.
The decision framework is explained in the complete planning guide, the drainage comparison and the quote worksheet. For tight spaces, print the closet measurement checklist.
