Kitchen Remodel Calculator
Most kitchen remodel calculators only count one trade. This one composes four — drywall, interior paint, flooring, and backsplash tile — into a single materials list, the way an actual kitchen remodel happens.
Backsplash vs paint overlap is handled automatically: the tiled square footage between your counters and uppers is excluded from paint area so you don't over-buy gallons. A full-height feature wall behind the range carves out the standard 18-inch run so you don't double-count the same 4 feet of tile. Every line item shows which underlying calculator produced it.
Works for galley, L-shape, U-shape, and single-wall kitchens. Cabinets, countertops, appliances, plumbing fixtures, lighting, and the range hood are not modeled — those are scoped separately in any real remodel.

How to Use This Calculator
- Enter dimensions: kitchen length, width, and ceiling height in feet.
- Add doors and windows: standard sizes deduct from paintable wall area automatically.
- Pick scope: Refresh (keep existing drywall, repaint) or Full demo (replace drywall, paint over new).
- Pick backsplash style: no tile (paint everything), standard 18-inch run between counters and uppers, or full-height counter-to-ceiling for open shelving / no-uppers walls.
- Enter total backsplash linear feet — sum of countertop runs that get a tiled backsplash. A typical 10×12 kitchen runs 12–16 ft.
- Optionally add a 4-foot full-height feature wall behind the range (only available with the standard 18-inch style).
- Pick floor type: ceramic/porcelain tile, LVP / vinyl plank, or hardwood / engineered.
- Pick wall tile material — only shown when you have a backsplash.
- Click Build my kitchen materials list — line items are grouped by trade with the underlying calculator linked on each row for full traceability.
How surface overlaps are handled
Backsplash tile area is excluded from paint area automatically so you don't over-buy gallons. When you add a 4-foot full-height range feature, that segment is subtracted from the standard 18-inch run before the tile section is sized — no double-counting. Drywall is only included on full demo. Floor area is calculated wall-to-wall (modern installs run flooring under cabinets) with kitchen complexity factored in for cuts around islands, alcoves, and base-cabinet toe kicks. Every line item shows the underlying calculator it came from so you can drill in for detail or override defaults on the standalone tools.
Frequently Asked Questions
Does this calculator include cabinets, countertops, or appliances?
No. v1 covers materials for drywall, interior paint, flooring, and backsplash tile only. Cabinets, countertops, appliances, sinks, faucets, lighting, and range hoods are not modeled — those are typically scoped and quoted separately by a cabinet shop, fabricator, or appliance retailer. The composer focuses on the trade materials a typical homeowner or contractor needs to source themselves.
How do I figure out my backsplash linear feet?
Add up the linear feet of countertop runs that will have a tiled backsplash behind them. For a typical L-shape with a 10 ft run + 8 ft run, that's 18 ft. Skip the section behind the sink window (windows aren't tiled), and skip islands (no wall behind them). For a U-shape kitchen with three 8 ft runs, total is around 24 ft. The calculator handles the standard 18-inch height — you only enter linear feet.
What's the difference between standard 18-inch and full-height backsplash?
Standard 18 inches is the conventional residential layout: countertops at 36 inches, upper cabinets at 54 inches, with 18 inches of tiled wall between them. Full-height runs counter to ceiling and is used where there are no upper cabinets — open shelving, range hoods that go to the ceiling, or feature walls. On an 8-foot ceiling, full-height gives you 60 inches of tile vs 18 inches of standard, so material costs more than triple per linear foot.
How does the range feature wall work?
Selecting the range feature carves out a 4-foot segment of your standard 18-inch backsplash and replaces it with a 4 ft × counter-to-ceiling tile section behind the range and hood. The math subtracts the 4 ft × 18" area from the standard run before sizing the feature, so you don't double-count tile. If your full backsplash is already counter-to-ceiling (full-height style), the range feature is moot — the whole run is already there — and the option is hidden.
Why does the calculator subtract backsplash from paint area?
Paint and tile cover the same square footage of wall. A typical 14 ft × 18" backsplash is 21 sq ft of wall that won't be painted — the calculator excludes that area from paintable wall surface so you don't over-buy gallons. Doors and windows are also subtracted automatically using standard sizes. If you want to override door or window dimensions, click through to the Interior Paint Calculator from any paint line item.
What kitchen size should I expect this to work for?
The calculator works for any kitchen between roughly 6×6 ft (a small galley) and 25×25 ft (a large open-plan kitchen). The Flooring Calculator inside is set to 'complex' room complexity by default because kitchens have many cuts — around base cabinets, island bases, fridge alcoves, peninsula returns, and toe kicks — which the NWFA recommends a higher waste factor for. If your kitchen is unusually rectangular with few obstructions, click through to the Flooring Calculator and bump complexity down.
Does the floor go under the cabinets?
The calculator assumes wall-to-wall floor area, which matches modern installation practice for LVP, vinyl plank, hardwood, and engineered wood — flooring is laid first, then cabinets sit on top. This is also the manufacturer-recommended approach for floating floors so the cabinet weight doesn't pin the field and prevent thermal expansion. For ceramic or porcelain tile, some installers tile only to the cabinet edge to save material. If that's your plan, run the Flooring Calculator standalone with the exposed-floor footprint instead of the full kitchen footprint.
Why is each line item linked back to a separate calculator?
This is a composer — it runs the standalone Drywall, Interior Paint, Flooring, and Backsplash Tile calculators with shared inputs and aggregates the outputs. Every line item shows which calculator produced it so you can verify the math, override defaults (different tile sizes, waste factors, paint coverage, complexity, etc.), or get pricing on the dedicated tool. The math is identical to running each calculator separately and reconciling the backsplash vs paint overlap by hand.
