Check to see if they are even strong enough to support a quartz top. Also, older vanities are usually lower than people are building them nowadays. Those openings do look tiny for drawers, and the new vanities can have nice soft-close doors and full-extension soft-close drawer guides. You may be much happier in the end of you replace them

That's a good point about the weight. They are new vanities with new wooden countertops. They just don't go with the house and it is not my style. I think the previous owners were going for a rustic, farmhouse look. I know I'd be happier with new vanities, but looking to see if others have better ideas to make it work. It's a shame to tear out what is new and high quality, etc. Is there a market for used vanities/countertops?

This house does have several unfinished projects. The interior width of the sides are 8.5" not including the 2" face framing on each side of the opening. The center opening is not quite 23.5 inches. For the base, there are two solid sides and 2 solid inner supports that hold the weight of the countertops; I assume plywood or mdf. Thank you!

Ultimately, you’ll probably want to replace the vanity. In the meantime, why not just get baskets to put into the open spaces. For the smaller spaces, just put the basket on the counter while in use.

There's a business near me that deal exclusively in remnants. I've bought and sold materials there before. The guy that runs it often times has remnants from stone fabricators, and a lot of times I see whole slabs with the sinks and plumbing still attached from remodels. The contractors would rather sell them to him for even a pittance rather than pay the disposal fees to dump them. You could ask a fabricator if there is a place like that near you. Otherwise, you could donate the wood counters with the sinks and plumbing attached to Habitat Restore. They don't pick up in my area, but you should be able to get that into a van or truck to take it to them. There are a couple other charities near me that take building materials. I was really surprised that one in my area took all of my kitchen drawers, glides, screws, door fronts, hinges, lights, counters, sink, and appliances that worked, vent hood, etc.

The tops really are pretty. Could you possibly re-use then to make something for your house? Such as a potting bench (the sink hole can be used to send trash and dirt down below to a trash can, or leave the sink put a cute plant in it). Or maybe a work station for your workshop, or table for your sewing room, etc, etc. You could even use the piece without the hole in it for a large cutting board for the kitchen or make a game table or an entry bench out of it.

If you decide you want to keep the cabinets and put drawers and doors on them, I would think a local custom cabinet builder would be someone to call. I have had great luck with local pros. One completely built my kitchen and then retired, but I found another local craftsman who refaced (new drawers, glides, door fronts, hinges) the vanities in my 3 upstairs bathrooms and my laundry room. If you don't know where to start to find a local custom cabinet builder, ask a highly regarded painter in your community. Even if they don't have a cabinet builder on staff, I have found that they tend to know the really good cabinet builders in the community because they see their work on all their jobs and often times work together for the same GC. My favorite painter referred me to the local cabinet person I recently hired because they are often in the same jobs and he knew how good his work it.

Thanks! Great ideas on repurposing. In fact, our large laundry room has no cabinets in it; one of several unfinished projects.

After investing in new countertops and sinks you'll still have the vanities which are, frankly, rather weird and not useful for storage. I'd replace them with useful vanities, one sink apiece, and without the lower makeup table whose space would be far more useful for drawers and shelves behind doors.

I tend agree with you about 'weird'.

It depends on your budget. If you've got the cash for new vanities then do that and get something that works best for you. If you're on a tight budget, then you absolutely can purchase after-market doors and drawers and install them in the existing. Our local Menards has some stock unfinished Maple Shaker doors, but if you need custom sizes, Barker Door is a good source.

Thank you, everyone for the advice. Since our laundry room lacks cabinets altogether, we will put these in there with a laminate top, and get new vanities for our bathroom. I needed to think this through, and appreciate your input.
