Is a solarium cheaper than a sunroom?
Solariums tend to be double the price of sunrooms and require a lot more in maintenance costs. And keep in mind that glass costs can really add up. Sunrooms have a high return on investment and usually have better warranties.
How much does a 12x12 sunroom cost?
You can expect to pay between $80 and $230 per square foot for a three-season room and $200 to $400 per square foot for a four-season room. Taking $300 as the average per-square-foot cost of a sunroom that can be used year-round, the average cost of a four-season 12x12 sunroom is about $43,000.
