Charging $600 for installation, which I’m guessing includes assembly, as well as removal of the old disaster.
ETA - in the FAQ they disclose that the cabinets are made in China.
RTA cabinets are heavy and generally need to be shipped via a freight company, the cost of which is based on weight and distance.
@gatormama Where are you located? That place you posted is in California, if you can find a place closer to home your shipping will be cheaper.
If you are in the northeast, take a look at this site: https://www.rtacabinetstore.com/ I’ve used them before and their cabinets are decent. And they have stuff on sale right now.
Keep in mind that any RTA (ready-to-assemble - the cabinets are shipped as pieces in a carton and you have to put them together) can be decent quality, but these are not top of the line cabinets. You generally get a plywood box and and solid wood door, which is better than your average big-box particle board cabinet, but the finishes are not as durable as a high end cabinet. I’ve used them many times in my rentals and they have held up well.
I was about to page you, NRE. 
You our RTA cabinetry expert.
Thanks for the link, @notrichenough (love your username )
I am in PA, which is definitely accounting for the shipping cost. I’ll investigate the NE place.
(I can’t duplicate his price, now that I try. He’s quoting me a good $400+ more than I get when I put what I think are the correct items in my cart. Might be steering clear of this guy regardless…)
This is a laundry room and I don’t care what the cabinets look like as long as they can hold multiple laundry detergent bottles without falling off the wall. I have mondo stuff to store in these cabinets - I must have the most strength possible, but they can look like garbage; I do. not. care.
So are you guys saying that there is NO plywood/hardwood to be found in the big-box stores? I shouldn’t even waste my time?
We are getting ready to start our guest bathroom remodel. It is pretty small. The same contractor we had for the rest of the house will do it. We will use the same flooring, tile, countertop, as we did in this summer’s master bath remodel. It should be fairly simple. Just replacing the bathtub and vanity, but using the same footprint. The vanity will be the same as the vanity in the master and the kitchen cabinets.
Any thoughts on medicine cabinet vs. just a mirror? Also we have a window in the shower/tub that tends to collect water from the shower in the window sill. Any way to remedy that?
Even high-end custom cabinets use particle board, but there are different grades of particle board, just like with lumber. The differences are in the quality of the doors, veneers, hardware, factory finishes, construction details (like dove-tailed or hidden dove-tailed drawers) and how well jointed the the pieces are. A box made with high-quality MDF or the like can be very strong and durable. You do get what you pay for. I don’t remember seeing plywood boxes at HD or Lowes, but I haven’t looked at cabinets there in forever.
No one uses actual wood for the boxes, it would be ridiculously expensive. And not all that desirable, as wood that size can split and/or warp. Most decent wood-stained cabinets will have solid wood doors, although some may use veneers, it’s worth knowing as the veneers can de-laminate or split over time, especially in high moisture areas. With white painted doors you can’t tell what you are getting by looking at it, so that’s a question you need to ask.
I typically add some screws when assembling these cabinets to reinforce the box, as I use them in rental properties and they don’t get treated gently. I don’t fully trust the cam systems these cabinets use.
For a laundry room, I would just go for the cheapest RTA cabinet you can find in the color you want, especially since you don’t care that much.
If you are anywhere near Conshohocken, PA, you can pick up the cabinets yourself at the place I mentioned, and save the freight completely.
All tradespeople mark up the materials and supplies they use.
If you tell him you will order the cabinets and he just has to install them, his price will probably go up a similar amount. 
If you (or you spouse) are at all handy, it is very simple to assemble and hang these cabinets. Especially since you don’t care if it looks perfect.
Laundry Room Cabinets:
From your description, it sounds like the cabinets “are falling off the wall”. If that is the issue, it doesn’t matter what they were built of, they were installed wrong. They didn’t get screwed into the walls properly for support. But I’m sure your existing cabinets have other issues also.
I’m going to put a big plug in for IKEA cabinets. They are great value for the money. And, they have all kinds of shapes and sizes. Look at their website. They come in flat boxes. You can pick them up at IKEA if you have a large enough car, or pay for delivery. The boxes are heavy so you’ll need help to carry them around. There are all kinds of great functional inserts and tall utility cabinets.
If you have any inclination to DIY, you can assemble the cabinets yourself. Or IKEA has a list of installers you can hire.
Bathroom Remodel:
The tile around your window was not installed correctly. The tile guy/gal should have built up a slope around the window so that all water runs off the ledge. No water should be sitting anywhere. It’s like a soap dish, slightly sloped. If there is no slope, and newly installed, you need to call tile installer back
Sorry…just re-read your post. Just make sure your new tile install is sloped away from window
Re: Medicine cabinets. They seem to be out of fashion, as far as I can tell. I would go with a mirror an no medicine cabinet. A mirror with an LED lit edge would add a cool twist to an otherwise boring bath.
+1 on IKEA cabinets. Their particle board is decent quality as far as I know. Better than assembled stuff you find at big box stores.
In my area, medicine cabinets are out of style also. Pretty framed mirror is best
If medicine cabs r out of style, where do u store the jars?
Thanks, we are not at all handy and I will cheerfully pay to get these assembled and installed.
But my dad and my husband did install these cabinets (before we realized we hate stuff like this, haha).
And they did it right, as the frames that are attached to the wall are still solidly attached; it’s the rest of the cabinet boxes that separated from the backs and are coming off the walls. The only things I can store in those cabinets right now are, like, cotton balls and similarly weightless items.
Holy cow, you need to rip those off pronto before they come crashing down!
you’re probably right. But they’re kind of frozen in place in this position and have been for over a year. I know I’m tempting fate but they’re over the washer/dryer and nobody is ever in there except for laundry and … eh, you’re still right…
We just had a similar experience in our kitchen. Cabinet frames still firmly attached to the walls; boxes were coming loose and separated from the frame. Because we are not in a position to demo the kitchen (though G-d knows it needs it desperately!), we got some cheap replacement cabinets from Home Depot. If they last five years I’ll be surprised. Maybe by then we’ll be ready to take the plunge and renovate.
When we did our hall bath we put in a pricey Robern medicine cabinet which I love. I didn’t do it in the new master bath because it was an outside wall and didn’t really fit the design I had in mind, but I really, really miss the cabinet. I’ve got drawers for my stuff, but it’s just not as easy to deal with.
If you have a side wall above vanity then put the medicine cabinet on side wall and pretty framed mirror above the sink
Bringing the “drawers v. cabinets” discussion here from the cleaning thread…
This kitchen has lots of lower drawers… and a large island, pantry wall with ovens, and a cabinetless wall:

(Our local paper ran a story about the lawsuit filed by two Chinese home buyers who are saying that their realtor colluded with the builder and was not looking after their interest, so as the result, they overpaid for the houses which they bought sight unseen. This is one of the two homes).
