Bow window prices will vary widely as they involve not only the windows, but also the cost of installation and the bow window box. While simply replacing an existing bow window will be much more reasonable in terms of project cost, enlarging or altering the opening will involve much higher labor costs. Explore our breakdown of bow window prices by windows,

Bow Windows Cost :: $1,900 to $9,000
Windows Only Price Range
The following price points (entry level, mid range, and premium) are for the WINDOWS ONLY. For the sake of simplicity, we will assume four windows as this is the most popular number of windows used for bow windows. Additionally, the price ranges below DO NOT INCLUDE the pre-made “box” that serves as the overarching structure, nor the labor cost to install the windows. Our breakdown of these costs can be found below this section.
Entry Level Pricing
Entry level bow window projects will often use four vinyl fixed frame windows that do not open or close. Additionally, these windows are going to be much more on the affordable side of the very large vinyl window market. So, limited options and upgrades (and possibly warranty timelines). While there are loads of cheap vinyl window manufacturers out there, an affordable vinyl window doesn’t mean it’s a bad window either. Here are our best budget windows if you are looking to keep those costs low (although the best long term return on investment is typcially found in that mid range category).
Price Range: $200 to $400 Per Window
$800 to $1600 For Four Windows
Mid Range Bow Window Prices
Mid range bow windows may or may not be fixed frame windows (which are less expensive than operable window styles). Perhaps a mid range set up will be two fixed frame center windows and two operable windows on either side. These side windows might be casement windows or double hungs (casements are the more common style). In terms of the window frames at this price point, it might be a higher end vinyl window or a more entry level fiberglass or wood window.
Please note: an entry level wood window often carries the much more limited warranty timeline than other replacement windows. My own take is that entry level wood windows do not provide very good return on investment. I would prefer consumers to buy a high end vinyl window with an interior laminate upgrade that looks like wood, but will last like vinyl.
Price Range: $400 to $800 Per Window
$1,600 to $3,200 For Four Windows
Premium Pricing
Premium window prices will typically be four wood windows, although higher end fiberglass, composites, or aluminum clad windows can certainly be in the mix at this price point as well. Additionally, one of more of the four windows will be operable – often a casement, awning windows, or double hung. Often, premium pricing will involve considerable upgrades to the windows themselves. Common upgrades include low-e2 and lowe-3 glass packages, metal hardware, lift rail reinforcements, and frame inserts for better strength and energy efficiency.
Price Range: $800 to $1500 Per Window
$3200 to $6000 For Four Windows
Bow Window Installation Cost
Consumers can expect to pay anywhere between $600 and $2,000 for window installation costs. This is a pretty huge price range, so let’s dig a bit deeper. If your project is simply swapping out an existing bow window for another, then the installation cost will be at that lower end of the price range.
However, if the swap also involves repairs to the existing opening that is going to hold the new bow window, then your install costs are going to rise. Typically, these repairs will be removing rotten wood and shoring up the area (new wood, flashing etc.) so that it’s watertight going forward.
At the top of the installation price range is the following: your new configuration (width, length, and/or depth) is different than the existing opening. Enlarging or altering the opening size typically involves quite a bit of labor, which obviously drives up the installation cost to that higher price range.
Installation Cost Only: $600 to $2,000
Bow Window Box Cost
Consumers can expect to pay $500 to $1,000 for the pre-made bow window box. While some higher end projects (intricate or highly customized configurations) will be constructed on site, most standard bow windows use a pre-ordered box as the overarching structure.
The process works like this: the local window company comes out and takes all the measurements and jots down the opening size, window sizes, space between the windows, etc. Then they place that order into the handful of companies around the country that specialize in making and selling these “boxes” — same companies make bay window boxes.
Generally, this process cuts down on homeowner costs due to the fact that this is more or less what these companies do day in and day out. Additionally, it insures a higher quality product since most local window companies are just not set up for these rather complex builds.
Box Cost: $500 to $1,000

Question For You
We are having a vinyl bow window put in that measures 96 inches by 51 inches with a white interior and exterior. Also, it has four windows with the two middle picture windows and the two outer are double hungs. The windows themselves are ProVia Aspect. This is the price quotes that includes the windows and all of the materials, supplies, and installation cost: $5335. Fair? Not fair? I really have no idea so getting your take on this is super helpful.

Janet, I would say that the price quote is quite fair. Now, that doesn’t mean I wouldn’t try and negotiate the window bid lower, but I think you are off to a good start. Certainly, I would say you want to collect additional quotes for some comparison shopping, but I like the bid you have thus far. Very solid I would say.
