A few to several thousand depending on cost of labor, window chosen, etc.

You're on slab? Have you investigated the costs involved in getting a drain to a new location with a slab foundation? You are undertaking costs that could actually diminish the value of your home. Changing a window will affect the exterior appearance of your home and perhaps not in a good way.

Perhaps there is another easier solution to your problem. Post a floor plan or more information. The followers on Houzz might be able to help you.

Beverly, yes on slab. here's a floor plan. I know the plumbing and electrical are other, big issues and that this will not be an easy or cheap project. Just exploring options.

Just moving the plumbing will cost thousands by the time you jackhammer the floor, tie into the plumbing, move 220V lines, patch floors... Burning money that you will never see back. Leave laundry where it is, invest in furniture for the space that will make it function how you want

Have you checked into what the value of home may change to with reducing it from 4 bedroom to 3 bedroom? That combined with the expense to do what you want could really leave you in a hole.

The room will make a great office - don't do built in stuff so it can covert back to a bedroom again and leave the laundry - not really sure how you would put those 2 together in that room and have either look/function well .

Do all your homework before hand and then make the best decision for you .

Good luck!

Debbie, we have another large office room that can become a 4th bedroom if needed. I want the current tiny laundry to be a walk in pantry. My main goals were to have a larger laundry space and finally hey my walk in pantry! But I do realize it’s a huge cost. Thank you!

I'd just use the room as an office with a free standing desk and leave the laundry where it is. You can add a table to the new office for folding clothes, or a free standing mudroom type storage unit since it is right across from your laundry area. It doesn't make sense to me to spend all that money changing it to a laundry room when it has great outdoor access and an attached bath. What are you trying to accomplish?

Calidesign, I want a walk in pantry for my kitchen and a larger laundry room. The current laundry room seems right for the pantry, but the new laundry room would have to go elsewhere. Alternatively, we could keep the laundry as-is, possibly extending it slightly into the powder room next to the laundry. The door to the backyard could still serve as a pathway from outdoors to the bathroom for guests and people who are using the pool, even if this room becomes the new laundry.

also in so cal. the slabs we're on make it a nightmare to move drains. Not only that, they would have to see how far down the pipes are. whenever you put in a drain pipe, it has to slope and meet w/ another drain, or the main sewage drain. if that drain you're going to tie into is higher than your sloped drain from the new position is, it won't work. Does that make sense? whatever you tie into has to be sunk down far enough to accomodate the new slope from the new drain.

and of course jackhammering up the slab to access the pipe and drain is a huge job.

ask me how I know ;)
(this is my husband plotting my death for redoing the master bath)

you'll need a plumber to determine that part of the equation.

The window you can find for a few hundred (just an inexpensive vinyl replacement), install may be 1.5K or more (they have to frame out a new window opening and demo the old stuff) , stucco repair, maybe another 1K, maybe more w/drywall on the inside.

The plumbing portion,,,,well, that could be 2K to 5K. just depends.

So, for a new window and laundry room, expect to pay well over 6K.

Beth, thanks for your detailed response ! I appreciate it!

you need to price this out. you need to decide if you want play the general contractor or have a general do it. The stucco exterior complicates things, You may want the whole side of the house re-dashed to avoid a patched look. This job will require many different trades to complete .

todd, I've had my stucco patched numberous times. There's no need to have the entire side redone. I've had numerous stucco patching done. Doesn't have to be expensive, you just need someone who knows their trade.

see where this window is?

it used to have french doors (this was actually an addition) My husband did the entire thing (demo, framing, new window install) but I called in someone to stucco it.

The patch looks perfectly fine. you can't even tell. no cracks, no seams, no bumps. I think I paid 700 for both the window and the door around the corner. The guy did a really good job

The portions that looks dark (this is right after the work was done) used to be an 8x4 window. We put in the french doors.

wish I had a better pic. few years later after painting. no cracks or obivous seams.

it's a heavy stucco pattern, so that helps hide any new seams.

Todd, I'm definitely hiring this job out. I'm just trying to see if I should even get estimates or if I'm completely off my mark. Thanks for your response.
