Countertop edge profiles compared — eased to waterfall, cheapest to priciest
Picking an edge is picking a fabrication tier. Eased, pencil, and bevel (Tier 1) are the only edges laminate supports and cost the least to run; bullnose, ogee, and Dupont are mid-tier; mitered and waterfall are built-up edges that bond two slab thicknesses, so they cost the most.

Countertop seam placement — where seams are forced and where they are forbidden
Seams are forced by slab size (runs over ~110″) and by inside corners. They are forbidden within 18″ of a sink or cooktop (AWI §3.3.1) and directly over a dishwasher (NSI 17-D-1). Green = allowed, red = forbidden.

Countertop overhang support — the seated cantilever limit and when a bracket is required
A seated overhang has a hard unsupported limit: ~6″ at 2 cm, ~10″ at 3 cm (NSI). Go past it and the stone cracks at the cabinet line — a deeper seating overhang needs a corbel or hidden steel bracket. A standard front overhang is only ~1¼″, so it never needs support.

Standard kitchen cabinet dimensions — base, wall, and tall cabinet sizes in a section
Standard cabinet sizes: a base cabinet is a 34½″ box + 1½″ top = 36″ counter height, 24″ deep; wall cabinets are 12″ deep, 30/36/42″ tall, hung 18″ above the counter; tall/pantry cabinets run 84/90/96″. These fixed sizes are what the take-off is built on.

How kitchen cabinet linear feet become a cabinet count — 3-inch increments and fillers
Base cabinets = ⌈ base LF × 12 ÷ 24″ avg ⌉, rounded up. Cabinets come in 3″ width steps, so a run rarely hits the wall exactly — 3″ fillers absorb the leftover at each end, and appliance openings (range ~30″, dishwasher ~24″) are subtracted from the cabinet run.

Kitchen corner cabinet dead space — why two runs of an L-kitchen don’t simply add up
Where two runs meet, one corner cabinet sits in both — the 24″-deep bands overlap in a 24″ × 24″ square. So an L- or U-kitchen’s run ≈ wall A + wall B − 24″; add both walls whole and you double-count the corner. A lazy Susan reaches the back — a blind corner leaves it dead.

Bathroom vanity clearances in plan — IRC and NKBA minimums around the vanity
Code sets the floor: a toilet centerline ≥15″ from the vanity edge (IRC R307.1 / IPC 405.3.1) and ≥21″ of clear floor in front of the lavatory, and the entry door must not swing into the vanity. NKBA’s 18″ and 30″ make the room comfortable.

Vanity height by sink type — why a vessel cabinet ships shorter
The cabinet height follows the sink: a standard 32–34½″ cabinet + ¾″ top lands the rim in the 34–36″ comfort band; a vessel bowl adds 4–6″ so its cabinet ships ~30″; an ADA lavatory caps the finished rim at 34″ AFF with open knee clearance. Pedestal and wall-mount lavatories have no cabinet — the fixture sets the rim.

Bathroom sink rough-in heights and double-vanity centerline spacing
Rough-in: the drain stubs 18–20″ above the finished floor, the supplies 20–22″. An 8″ widespread faucet drills 3 holes (one 4″ each side of center); centerset is 3 holes 4″ apart; single-hole is 1. Two sinks need centerlines ≥30″ apart (IRC P2705.1.5; NKBA 36″), so a double vanity runs 60″ or wider.
