A full bathroom with shower/tub costs roughly twice what a half bath (toilet and sink only) costs due to additional plumbing, tile, and fixtures.

Adding a bathroom near existing plumbing (above or adjacent to a kitchen or other bathroom) significantly reduces pipe routing costs.

📏
Flooring Type

Tile floors in bathrooms cost more to install than vinyl or laminate but offer better water resistance and durability in wet areas.

Fixture Quality

Basic fixtures (toilet, vanity, tub) start around $500 total while mid-range sets run $1,500–$3,000 and high-end can exceed $5,000.
