Moulding would not stop water from seeping under that cabinet. That is the typical way they are finished, flush with the top. if worried about water you should not have used this type of design.

I know nothing so this could be a terrible idea, but could you put a head of caulking or something around the perimeter of the cabinet to create a bit of a seal?

Molding will not stop water from reaching the cabinet with a very poor design. The cabinet is installed. It's going to have damage. But not because of a lack of molding. Because it is about a foot too close to the sink on both sides. That whole thing is not big enough to have that sit there. Not at all. You would need 36" between sink centers, PLUS the width of the cabinet, to have that be functional. Get rid of it.

Yes. Cabinet company is willing to caulk. Unacceptable. No way to caulk this without looking tacky. A built in n cabinet(IMHO) should be “built in.”

Molding stopping water? You’ve lot the plot. There isn’t room for that atrocity there. Get rid of it.

But what did you expect? I’m fairly confused about how you thought this would look any different. As others Ange said, you don’t have a lot of space. This wasn’t planned super well.

If you insisted on that, I still wouldn’t do it. There isn’t nearly enough room for it to do anything but subtract from the usability of the sinks. Even the better designed towers that have drawers snd enough clearance room will benefit by placing them on a fabricated pedestal piece of the counter, by your stone fabricator.

As Rasmussen notes, it could've been designed with a stone base, but since it's very close to the sinks, there will still be water splashing on the wood. That style only works if there is far more available space between the sink and the wood. Best choice now is remove it. The finishing piece from the cabinet to the ceiling is not attractive either.

ETA: I think I see shower wall tile used as shower curb material? Why wasn't a solid material (counter) used on that/any horizontal surface as is customary? You may eventually have more issues than inadequate space for this cabinet unfortunately.

Perhaps removing and replace with a shorter cabinet to help with existing footprint?

Is this cabinet really even needed?

Maybe get rid of the crown moulding (or cornice) and raise the cabinet up and mount to the wall?

My cleaning ladies would destroy that cabinet in a few visits! I had to ask one of them not to flood the bathroom counter with water when cleaning!

Two recessed mirrored medicine cabinets would have provided lots of storage for everyday toiletries. I have used several from Robern and been happy with them.

This was just installed. I did not design the layout. This is 100% cabinet company. I trying to work with them. It’s not going well.

Is this your home? If so you have a say on how it comes together. If you don’t like this get it removed.

Look, that thing was a mistake. It’s a good thing that it is so easily fixed! Just remove it. Next time, work with an actual kitchen and bath designer. Not a cabinet seller that says yes to every bad idea that you have, just to get the sale price higher gor a bigger commission.

Looks like your cabinet company provided a typical installation.

This cabinet was boosted on the stone backsplash.

I was going to post a photo similar to the last one posted by Beverly in her comment above. I learned from Jan Moyer that you need to wrap a counter cabinet (in your bathroom or on the same run of countertop as your sink or cooktop in a kitchen) in order to protect it from water/splatter damage.

Can the cabinet be removed + a base added that uses your countertop material in order to raise it up? Then you can use caulk around the edges of the countertop material in order to prevent water from seeping underneath the cabinet ( not that it will ruin the cabinet because it's raised - but I wouldn't want water just sitting underneath the raised portion either).

I've seen a photo posted here on Houzz where someone had a marble base incorporated under her vanity tower in order to raise it up off the countertop. It wasn't super thick - but she said that it helped keep water off of the wood. If you need for me to find it, let me know.

Unfortunately, your doors come down too low for you to just simply have the cabinet wrapped with countertop material all the way around. However, you could add pieces to the sides + caulk them - it would help some (it would be like a side splash on each side of the cabinet).

IMO remove it put on the floor somehwere else you have now lost precious vaniy space and to boot a silly idea for storage . If not possible then the idea of raising a bit off the counter is the only answer

"This was just installed. I did not design the layout. This is 100% cabinet company."

No, but you approved it. I wouldn't try to find a way for it to work here. Instead, put recessed medicine cabinets in and recessed shelves above your toilet or elsewhere in the room.

If you dont want caulk. Or a pedestal. What exactly kind of “molding” do you think should be added? That won’t interfere with the operation of the door, or look stupidly cut short tacky when you do open the door? What does that mystery molding look like? The waterproof wood one that doesn’t allow water to seep underneath it too?

What, exactly do you want to happen? Magic?

I think the choices are to either live with it and see if you can be careful with water & cleaning products and see what happens or remove it and have it reworked so it can sit on a solid surface base (that’s likely beyond what you spec’d with the cab company so maybe best to cut bait there and find a pro who can come in and customize it)

Why is the OP denying they requested this cabinet? There is just no world where the contractor said "hey how about I build a cabinet on the too small counter"! How does putting a 1/4 molding along two sides of a cabinet against stone make it 'built in"? I've never understood this cabinet in a bathroom. I would feel so crowded when brushing my teeth!!

Hopefully the backsplash can be fixed if the cabinet gets removed.

Better to have large recessed medicine cabinet/mirrors

Wow, unanimous comments on Houzz. Almost unheard of. Please take everyone's advice and remove the cabinet to use elsewhere.
