What is a Sunroom?

Sunrooms are also known as solariums, 3-season rooms, or 4-season rooms. They are made using glass panels and a frame, which is constructed onto the side of your property. The idea being it will give you extra living space, while allowing more natural light into your home. 

Sunrooms are designed to capture the warmth of the sun, so that you can enjoy the space even though you aren’t fully outside. Sunrooms can be used for any purpose including dining, lounging, and even a home office or gym. 

Costing less than a traditional extension, sunrooms can be constructed in 2-3 weeks on average. The size and shape of sunrooms vary dramatically, as do the materials they are made from. They offer a seamless connection with the main portion of your home and the outdoors.

How much does a Sunroom cost? 

The cost of building a sunroom is usually measured in square feet. Expect to pay anywhere between $130 and $210 per square foot in Canada, depending on the quality of materials you use.

What changes the price of Sunroom Installation?

The cost of sunroom installation varies depending on several factors, including: 

  • Sunroom type

  • Sunroom size

  • Foundation

  • Frame material 

Sunroom type

The type of sunroom you choose will determine the price, as each has a different method of construction. On the lower end of the scale, 3-season sunrooms can be constructed for as little as $12,000. The reason for the cheaper cost is due to the reduced insulation, meaning additional heating or cooling measures will be required to deal with either temperature extreme. At the top end of the price scale is solariums, which can cost anywhere between $34,000 and $79,000 on average to install. Solariums can be of incredibly high specification, with a sleek and modern appearance. Though they are more expensive, they will add the most value to your property.

Sunroom size

Sunrooms can be custom built to any shape or size. This makes them flexible additions to your property, as it doesn’t matter whether you have lots of outdoor space or just a small yard. Price-wise, the larger the sunroom, the more expensive it will be to install. 


Just like your home, a sunroom needs quality foundations in order for the building to be stable. Simple sunroom designs can sometimes be built on top of existing patios. Though if you want your sunroom to connect with your home and have the same level flooring, a foundation will need to be dug out and set with concrete. 

Frame material

Sunrooms frames can be made from vinyl, aluminum, or wood. Each material has different properties relating to insulation and aesthetic appeal. Therefore, expect the cost to vary depending on which material you opt for. 

Typically, vinyl is the cheapest material, aluminum is mid-range, and wood is the most expensive material.

Is it worth getting a Sunroom?

If you are looking to create more usable space in your home without building an extension, then sunrooms are the answer. Sunrooms come in a variety of sizes and styles, meaning there’s something to suit every property, not to mention budget. Not only can sunrooms add value to your home, but they can be enjoyed in so many different ways. Compared to an extension, sunrooms are typically much cheaper to complete too.
