The bath counter surface. Smaller than a kitchen run, so premium stone is more attainable; moisture and cosmetic-product resistance matter more than heat.

Task lighting at the mirror. Best placed at both sides at face height to eliminate shadows; a single overhead fixture alone is the most common lighting mistake.
See also: Wikipedia — Light Fixture
Positioning light at the mirror to eliminate face shadows — ideally sconces at both sides at ~66 in., not solely an overhead fixture. A design-and-electrical rough-in decision.

The countertop on the vanity, often with an integrated or undermount sink. Common materials are quartz, cultured marble, and solid surface.

A material that limits moisture diffusion through an assembly to control condensation. Correct placement is climate-dependent — wrong-side vapor barriers trap moisture and cause rot.

Official permission to deviate from a zoning requirement (e.g., to build closer to a property line than the setback allows). Requires application and usually a hearing.

A thin layer of a finish material bonded to a cheaper substrate — wood veneer on cabinet panels, stone or brick veneer on walls — delivering the look without the solid-material cost.

A tall faucet sized to reach over the rim of a vessel (above-counter) sink. Height is matched to the specific basin to avoid splashing.

Gases emitted by some paints, finishes, and adhesives that affect indoor air quality. Low- and zero-VOC products are widely available and recommended for occupied remodels.

A high-wall tub with a watertight door for step-in entry and seated bathing, an accessibility fixture. Long fill/drain times and cost are the trade-offs.
See also: Wikipedia — Bathtub
A toilet mounted to an in-wall carrier with a concealed tank, floating off the floor. A premium space-saving look that requires opening the wall and a carrier system.
See also: Wikipedia — Flush Toilet
A faucet mounted in the wall above the sink rather than the deck. A design statement that must be plumbed in the wall during rough-in and set to the basin geometry.

A continuous barrier (sheet or liquid-applied) over shower walls and floor that keeps water out of the structure. The make-or-break of a leak-free tiled shower.
See also: Wikipedia — Waterproofing
The wax seal between the toilet base and flange that prevents sewer gas and leaks. Replaced every time a toilet is reset; failure causes subfloor rot.
See also: Wikipedia — Flush Toilet
A fully waterproofed bathroom where the shower is open to the room with no enclosure, the entire floor sloped to a drain. A design-forward, fully tanked build.
See also: Wikipedia — Wet Room
The wall built to house the bath's supply and drain-waste-vent plumbing. Keeping fixtures on the existing wet wall avoids costly new drain and vent runs.

A tub with water jets driven by a pump. Requires a dedicated GFCI circuit and access panel; declining in popularity versus air tubs and soaking tubs.
See also: Wikipedia — Whirlpool/Jetted Tub
A faucet with separate handles and spout mounted independently 8–16 in. apart. A higher-end look that requires a three-hole sink/top.
