Bay windows prices will range anywhere from $1,500 to $6,000 plus, which includes the replacement window cost (for 3 windows) and the installation costs. Bay windows are essentially three (or more) windows that are connected at an angle and bump out the wall in which they are installed.

Bay Windows Prices :: Project Basics
Most times when you order a bay window, the company giving you the bid will write down the dimensions, details, etc. and give you a price quote for the work. Then they will turn around and order the "bay-box" from one of several companies in the U.S. that specializes in bay window boxes or housings. Th bay-box company (not an official name fyi) will then fulfill the order to spec and send the finished product back to the window company.
The company will then insert their own windows into the three pre-made openings and then drive to the job site where they will install the entire bay-unit. This method is actually much easier than the alternative, which is to custom make the bay window on site. Some high end projects (often with very specific detailing and/or requirements) will use this method, but homeowners will definitely pay a premium for this time-consuming endeavor.
Regardless of which method is used, bays (and bows) can be beautiful additions to homes, adding charm and elegance, as well as wonderful pockets of space that can be used as eating nooks, reading areas, etc.
Bay Windows Prices :: Entry Level
Entry level projects will range from $1500 to $2500 fully installed. These will almost always be premade units (bay-boxes) that a homeowner can order using either stock or custom sizes and dimensions. At this price point, it will usually be less expensive fixed frame vinyl windows, which is a good thing for energy efficiency, but reduces your options for air flow. Size wise, these projects will typically be smaller and less involved - thus the less expensive price point. From an installation perspective, the existing frame should be in good condition - if the installation crew has to do work on the frame to get it ready to handle the weight of the bay window, it may push the price point into the next category.

Bay Windows Prices :: Mid Range
Mid range projects will range from $2500 to $4000 fully installed. Projects at this price point will be either premade units or custom orders that are either put together at the factory or assembled on site depending on the project specifics. Usually, this will be larger in dimensions to the entry level projects. In terms of the windows themselves, there will usually be more options available in terms of the frame color, finish, and material. You nay have an upgraded glass package with a nice low-e glass option, mid grade spacers and fills. Homeowners can also expect more options in terms of the actual window styles where the middle window is fixed and the two sides will be casements or double hungs that can provide better ventilation and air flow.
Price Range: $2500 to $4000 Fully Installed
Bay Windows Prices :: High End
High end projects range in price from $4000 to $6000 plus fully installed. These are nice additions to a home that will almost always use a high quality wood interior with an aluminum or fiberglass exterior cladding for strength and durability. They are often custom jobs that again can either be built at the factory and brought out be the factory installers or assembled onsite. Expect top of the line glass and hardware with lots of upgrades and options thrown in - especially on the higher end of this price point. Many of the set ups will include casements on the side windows for added ventilation, although some homeowners prefer to stick with fixed or non-movable windows because they feel they add to the overall beauty of the bay window set up.

Bay Windows Prices :: Installation Cost
We've included the window installation cost in the ranges above, but it is worth noting how much the install is adding to these projects. Typically for premade units a crew of two or three installers is required for the installation. For custom installs onsite, there are two installers that are framing out the existing opening to accomodate the new bay window. This can be a time consuming task that must be done correctly to handle the weight of the bay and not cause any long term damage to the wall where it is going.

Bay Window Cost
We got a bid on a bay window that consists of three casements.
The KHPP Meridian series for $3876
The second is for RITE - $4803 Rite Windows Reviews
RITE seems to get the better review, but KHPP seems better made.
Emily - Homeowner - from 2023
[Site Editor's Answer]
Emily, I can't speak to the company portion -- mainly because I was confused which Long Home Products branch I was looking at :) but the Mass. LHP that I saw received good marks on their installation. Window wise, the KHPP Meridian is a great window. Very high quality. I think you stick with LHP - but you call them back and say something like we are a little bit concerned about the installation as we did see a couple of "not so great" reviews.
Once they get done defending their reviews, you ask them how you can get their very best install team and that you're happy to be flexible on the install date but you HAVE TO GET THEIR VERY BEST because you're partner/spouse is such a perfectionist (or something like this). This should work...

Hi Dane, I was quoted around $6000 for a OKNA bay window full replacement (1 picture, 2 casements). Dimensions of bay is roughly 105" Wide and 72" High. This includes materials and labor. If the existing roof is not properly mounted, another $600 would be charged to remove and remount properly. Okna Windows Reviews
Does this sound about right? I am located in the South Eastern PA.
Lucy - Homeowner - from 2023
[Site Editor's Answer]
Lucy, when it comes to bay windows prices tend to fluctuate A LOT. Some companies don't want to hassle with sending them off and ordering custom "boxes" and then having to do what amounts to a pretty difficult installation (at least compared to a normal replacement window). So they might bid it out at a high price. This actually looks like a price I would expect for that sized bay window, but it's still tough to tell.
My suggestion here is to get some additional bids to compare this one to. You should have lots of options in your area.
Okna is a great brand though and I would consider this to be a great start!
Here is my list of good and great brands in case you want to continue the search.

[Lucy's Reply]
I filled out the quote request as you suggested, easy peesy. We'll see what else we get. I’m in a suburb of Detroit, MI
I did call OKNA, but they have no representation in Michigan. There is a Soft-Lite dealer in a more upscale suburb than ours that is not too far away.
I like to be a good steward of the things I’ve been given, and and typically appreciate and support the efforts and work of environmental efforts, like Energy Star.
I’m also aware that that there is "point of diminishing return” when it comes to efficiency.
Given that purchasing an Energy Star window is a must for us, what is your recommendation on attempting to select one that complies with the new version 7 specification going to effect this October, or selecting a window in Energy Star’s 2023 “Most Efficient” ESME program?
Thanks!
Lucy - Homeowner - from 2023
[Site Editor's Answer]
Each region is different so you really need to speak with the rep and make sure that the series selected complies with the program. The series I recommend are excellent, but even some of those don't meet the stringent requirements. It's still a bit of the wild west when it comes to getting an Energy Star compliant window.

Afternoon Dane, I did seek out a Soft-Lite vendor near me since you apparently have high regard for them and received an in home verbal quote on an Elements (their recommendation)
Bay window cost @ $12,562 for the double pane Low-e Glass with Super spacer.
So it looks like its now between the Soft-Lite and the Sunrise Bay with Omega 12 glass package @ $6600. Soft-Lite Windows Reviews
Would you maintain that the Sunrise is still the best value? Or is the Soft-Lite really worth the difference? We can do either, but are looking for best bang for the buck, but also don’t want to pay a lot more for features providing diminishing returns.
Do you have any concerns about Sunrise build quality or build changes now that they have been taken over by MI? Is the Sunrise still being manufactured in the original Sunrise facility where they still have control over it? It doesn’t seem that you have had a lot of confidence in MI products in the past.
MI has renamed the Sunrise line the “V4000 Sunrise Series”. >MI Windows Reviews
Thanks sir!
Danny - Homeowner - from 2023
[Site Editor's Answer]
Danny, the Soft-Lite Elements, although excellent, is definitely NOT worth double the price that they are asking. The Sunrise is certainly the better value of the two --
I have done quite a bit of research and heard from consumers who have received bids that the V4000 series is the exact same window as the Sunrise Vanguard -- they have not touched the factory that makes these windows, but they do carry the MI label now. Since it's just the label, I think you are go to goon this.
Perhaps there are no companies in your area if you filled out the form but did not hear back. Usually you will received two to three responses within the hour. You could fill it out again and collect a few more bids or go with the Sunrise option. Your call :)

Project Price Quote
Hi Dane, we are considering replacing a double hung kitchen window with a vinyl white bay-window. Some of the manufactures that the contractors use in our area include:
Alside Mezzo
Softlite
Simonton
We are currently getting estimates. One place gave us an estimate of 5,000 - 5,200 for the Softlite. A bit more than we would like to spend. Does that seem high?
Can you explaine the differences and which you would recommend as your choices?
Karen - Homeowner - from 2023
[Site Editor's Answer]
Karen, the best brand of the three is the Soft-Lite -- by quite a bit I would say. Simonton is a good brand with their premium series, and Alside is just kind of meh for me. Bay windows cost are tricky because there are so many variables in terms of size, configuration, etc. so I think getting multiple bids is especially key for honing in on nice value in the marketplace...I have a list of recommended bids if you'd like to take a look.
