Three-Season vs. Four-Season Sunroom: Which One Should You Buy?


Are you undecided between a three- or four-season sunroom? While both additions come with distinct perks, the right one for your home really comes down to you. If you’re having trouble choosing, this quick guide will give you a quick rundown of each structure and go through what to consider before making your final choice.

While they might look the same at first glance, the main differences between three- and four-season sunrooms come down to how you use them. Here’s a quick overview of each one to give you an idea:

Three-Season Sunrooms

  • Great choices for spring, summer, and fall
  • Generally not equipped with a heating system or advanced insulation
  • Not winter-friendly
  • More budget-friendly option
  • Not suitable for living

Four-Season Sunrooms

  • Designed for year-round usage
  • Comes with proper insulation
  • Hooked to your home’s HVAC system
  • Great for places with extreme temperature fluctuations
  • More expensive upfront
  • Better long-term resale value

Questions To Ask When Choosing A Sunroom

Both sunrooms offer endless lifestyle benefits and another cozy space in your home. So, how do you know which one is right for you? Before buying, ask yourself these three questions:

When Am I Using The Space?

Knowing when you’ll use the space helps you determine whether you’ll need to hook up your HVAC system and add proper insulation. If you want your sunroom to be somewhere to relax year-round, a four-season one would be the best option. But if you simply want an extra place to store your stuff or host summer parties, a low-maintenance three-season can do the trick.

What’s The Climate Like Where I Live? 

Climate has a significant impact on the type of room you’re getting. Three-season sunrooms are best for mild climates where it never gets too hot or too cold. But with freezing Northeastern winters and hot summers, these structures may not be exactly comfortable year-round unless you invest in portable heating and cooling options.

What’s My Budget?

According to Angi, four-season sunrooms are more expensive and can range between $25,000 and $80,000. On the other hand, three-season rooms are much cheaper and cost between $10,000 and $40,000. Both are a big investment, but three-season sunrooms still remain the more affordable alternative if you want an extra space for your home.
