A standard 3-bathroom setup typically ranges from $15,000 to $25,000. Costs depend on fixtures, finishes, and layout complexity. Key expenses include plumbing upgrades ($2,000–$4,000), high-end toilets ($600–$1,500 each), double vanities ($1,200–$2,500), tile work ($2,500–$5,000), and lighting ($500–$1,200). Adding energy-efficient fixtures may raise initial costs but lowers long-term utility bills.

Expanding to 4 bathrooms increases total investment, usually between $22,000 and $40,000. Major cost drivers are additional plumbing lines, larger fixtures, and expanded tile coverage. Upgrading to smart showers or dual sinks adds $1,000–$3,000 per unit. While upfront, extra bathrooms enhance resale value and daily convenience, justifying the extra expense for larger households.

Beyond fixtures, hidden expenses include structural changes like wall reinforcement ($1,000–$3,000), new electrical wiring ($800–$1,800), and plumbing rerouting ($1,500–$4,000). Permits and inspections may add $1,000–$2,500, especially in older homes. Budgeting 10–15% extra ensures unforeseen issues don’t derail your project.
