Sunroom Guide for Homeowners

What Do Sunrooms Cost?

The price of a sunroom can vary depending on the size, materials, and features. However, many companies now offer modular or prefab sunrooms, which are more affordable and quicker to install than custom-built options.

Here’s a general range:

Small 3-season sunroom: Starting around $8,000–$15,000

Mid-size 4-season sunroom: Typically $15,000–$30,000

High-end sunrooms or custom builds: $30,000 and up

Some installers offer financing options or seasonal discounts—making it easier to start planning without a large upfront cost.
