Sunroom Styles: 3 Season Rooms vs. 4 Season Rooms

A sunroom is the epitome of a luxury living space.  The ample natural light and the sleek sense of style is a homerun for homeowners. You’re going to love your new sunroom, there’s just one big question you need to answer before renovating: do you want a 3 season or a 4 season room?

As the names imply, a 3 season room can be used in the spring, summer, and fall (3 seasons) — while a 4 season room is perfect for year-round enjoyment. Learn more about the differences between the two, the prices for each, and which one is best for your renovation.


Contrasting Both Sunroom Types

Inside 4-season sunroom

They look the same from the outside but the way they’re built makes all the difference regarding when and for how long you can enjoy them. Both 3 season and 4 season rooms are great — and that’s why we build both at Choice Windows Doors & More. It’s not about which is better, but which is better for your needs and your budget.

These are the main differences between the two sunroom types that account for the extra season of use:

  • 4 season rooms are built using structurally insulated panes which keep these sunrooms cool in the summer and warm in the winter.
  • 4 season rooms often come built with some type of climate control or HVAC system.
  • Generally, the glass used in the windows of a 4 season room is superior at regulating indoor temperatures.


These are the main similarities that you’ll enjoy no matter which type of sunroom you choose:

  • Both additions are sealed to the outside, as opposed to a screened-in porch which is not.
  • Both types of sunroom feature fully vinyl windows and walls.
  • When built by Choice, 3 season and 4 season rooms are designed to match the style of your house.


3 Season and 4 Season Rooms’ Costs Compared

The main reason that homeowners opt for a 3 season room is their price. Simply put, they know they won’t use the space as much during the winter, so there’s no reason to pay extra for it.

So how do the prices compare between 3 season and 4 season rooms?

Generally, 4 season sunroom styles cost about twice as much as a similarly sized 3 season room. This price difference accounts for the superior window glass, added insulation, and the HVAC system.

As is the case with all things pricing, this is just a ballpark estimate. To find out what your sunroom project will cost, we recommend scheduling a free in-home consultation.


Which is Right for You?

Like we said before, both sunroom types are fantastic and that’s why we install both. There’s really no right or wrong answer — only what’s right for your house and your budget.

Generally, if homeowners are on the fence, we recommend going for the 4 season room, simply because its better to have options you don’t use — rather than missing ones you wish you had.

However, there are a few specific cases in which we recommend opting for the streamlined 3 season room. Firstly, if you have a winter home, and won’t be in PA much over the winter, you won’t need the added comfort of a 4 season room. Another time we recommend choosing the 3 season room is if it’s a matter of budget. If you can only afford to get a premium 3 season room or a questionable-quality 4 season room, its always worth it to build it right.

It was amazing from start to finish. We had Brian Sheehe out to give an estimate to replace 4 drafty wooden windows with vinyl ones and to replace two very old wooden entry doors. The project scope included widening our front door from 30" to 36," installing a new header and patching the interior plaster with drywall and mud.Estimate went great, no pressure, and he listened to what we wanted and needed. Choice was the only company of the three places we contacted who would widen the front door, and Choice came in with the lowest estimate at around $5000 (in 2016). They also were the only ones who would allow me to paint my new doors without voiding the warranty.They came out with a crew of at least 4 people on a day when snow was expected in the afternoon, and they called in an extra person to finish all the work in a little more than half a day before the snow came. I'm still not exactly sure how they installed the new header and front door, new trim molding, patched the the drywall above the front door, mudded, and sanded it smooth all within a half a day but they did and all I needed to do was touch up the paint in that area - you cannot even tell where the edges are, it was that smooth.Everything has continued to work great over the last 4 years since installation in Feb 2016. It was so great to work with people who cared about my house like I do, and I will be calling them again with future projects.

My uncle found you online and suggested you to my grandparents. They are thrilled with the work you did and would recommend you to anyone asking for a good door repair service. They just got their bill in the mail and were relieved to see it didn’t cost an arm and a leg. 10/10 would recommend.
