Reverse Osmosis System Cost Guide for Builders

Understanding Reverse Osmosis System Cost in Residential Construction

In 2025, the cost of reverse osmosis (RO) systems for residential construction varies significantly based on system type and installation complexity. Entry-level under-sink units range from $350 to $750, while mid-range whole-house systems for 2-3 bath homes cost between $2,800 and $6,000. Premium high-capacity systems with smart features can exceed $12,000. These figures include hardware, installation labor, and necessary materials, crucial for accurate project bidding and client satisfaction.

2025 Cost Table for RO Systems

System Type	Cost Range
Entry-level under-sink RO unit	$350–$750
Mid-range whole-house RO system (2–3 bath home)	$2,800–$6,000
Premium high-capacity RO with smart features	$7,000–$12,000+

Staying updated with reliable pricing sources is essential for maintaining competitiveness in the construction market.

Key Cost Drivers in RO Systems

Water Chemistry & TDS Levels: Complex water sources require larger systems with additional pre-filters.
Desired Output Volume: Larger systems increase both unit size and setup time.
Plumbing Complexity: Retrofitting demands more labor compared to new installations.
Storage & Pressure Needs: Atmospheric tanks are cost-effective but require boosters, while pressurized tanks have higher initial costs.
Electrical & Drain Requirements: These can increase project costs by approximately 10–15%.
Advanced Features: Options like smart monitoring significantly raise prices.
