Finish Layout & Materials Planner / no guesswork hidden
From room dimensions to a ready-to-buy plan.
Coordinate tile, paint, trim, package rounding, and budget in one reproducible finish schedule. Keep waste and layout assumptions editable.

Your working plan
Computed locallyA finish schedule you can hand off.
Quantities reconciled to purchasable units
Tile quantities use a conservative grid with no reuse of edge offcuts, then add your allowance. Paint and trim are rounded separately.
Material budget
USDBefore you act
- A rectangular, straight-lay grid is assumed. Herringbone, diagonal layouts, pattern matching, irregular rooms, movement joints, and reusable offcuts need separate planning.
- Adhesive, grout material, primer, ceiling paint, labor, delivery, tax, and tools are not included.
- Verify wet-area waterproofing, electrical, plumbing, structural, and permit requirements with qualified professionals.
Purchase and installation schedule
| 1 · Verify | Substrate / waterproofing | Not calculated | Not included | Confirm substrate, flatness, moisture, and installation system |
| 2 · Order | Tile | 11 boxes | $396.00 | Confirm lot, orientation, transitions, and actual box contents |
| 3 · Finish | Wall paint | 2 gallons | $90.00 | Surface preparation and manufacturer coverage |
| 4 · Fit | Trim | 46 linear ft | $115.00 | Finished floor elevation and opening measurements |
Centered grid planning
| Room length | 6 | 23.69 in |
| Room width | 10 | 11.44 in |
Calculation notes & limitations
Floor area = length × width. Wall area = 2 × (length + width) × height − opening area.
Grid cells along a dimension = ceiling((room dimension + grout joint) ÷ (tile dimension + grout joint)). Every cell consumes one tile before allowance; this is deliberately conservative.
Paint gallons = ceiling(wall area × coats ÷ entered coverage). Trim excludes the entered opening width, adds allowance, and rounds to feet; actual stock lengths can require more.
The method is part of the tool.
Measure the room, wall openings, and trim exclusions. Enter actual tile dimensions and packaging rather than nominal dimensions alone.
Calculate a conservative straight-lay grid, show centered edge pieces, add explicit allowance, and round to boxes.
Calculate wall-paint coverage and trim independently, then combine material costs in a staged purchase schedule.
