That looks like custom work to me.

Hey, your Comments are snarky and useless. Please stay off threads if you can’t add value. @JuneKnow

Those are custom made by the countertop company. call your granite guys for a estimate.

While custom may not be 10K unless the installation is larger, 5-7K wouldn’t be out of line for what’s pictured. A slab of a high quality interesting stone can be 3-5K all by itself. It’s not buildale by just anybody that calls themselves a fabricator. The 0 radius corners are a challenge to keep clean as well.

Betting these are custom-fabricated, designed by the client's designer.

Full custom, designed by a designer and engineered by a craftsperson. Typically 5-15K depending on size and material. I know of a 30K 10’ trough installation in a local nightclub, created by one of the artist fabricators that I’ve used. The custom stainless steel support and hidden expert plumbing are all part of the overall look, and need to go in while the walls are open. It adds up.

This company‘s products are only available through dealers and they have provided that information, so just have to enter your postal code.

At least you can get a ballpark vs guessing and may also see alternatives you may like. Hope this helps

@JuneKnow dude, get off my posts. Your negative and no value add comments are not needed.

Yes custom, and the top pic the sink is floating/cantilevered which might be where JuneKnow got her $10k number.

That floating look requires specialty wall bracketry, and the brackets require side access to the wall studs, so you need to make this installation when the walls are open to the studs. Then the wall itself must be able to withstand the load of the stone floating sink. So costs will arise not just from the custom sink itself, but from the requirements needed to install and support it, and also the type of skilled labor needed for this job which commands top dollar.

Thank you. Helpful!

@Shannon_WI is a floating sink easier to install if the floating sink was less heavy/ made of typical white stone material?

Looking at something similar in loft bathroom remodel. The SIENA RECESSO CONSOLE from Stone Forest (pictured in this thread) is approx. $4,500. The price and weight are issues for us so we're passing on the concept. Even if we could find it at a lower price, the weight is a big issue that can't be overcome in a loft condo building. Love the look, though.

I have a (not custom) wood vanity with a marble linear drain in my master - it looks gorgeous and super modern but the functionality is terrible. Because the drain is off to the side of the trough, the whole back of the sink fills up before it drains out and leaves gross dirt on the other side (the non-drain side). Do not recommend.

(I put a linear drain in the shower too and that’s also not great for maintenance, though very beautiful. So either only custom/expensive linear components work vs my normal budget ones, or those expensive homes and hotels have housekeeping every day!!!)

@Girl World - what did you decide to do re: marble floating sink/vanity? I’ve been researching this topic a bit over the past few weeks. I’ve been aasending messages back and forth with someone in Italy about habing one custom made. It will be expensive - but not as expensive as everyone thought in above comments. I will have to make sure that I’m confident that my contractor will be able to install. He will be installing a custom floating wood vanity in my masrer bathroom soon. A little different - but I will also be installing a heavy quartz countertop with a thick mitered edge. The countertop will be supported by separate brackets on the wall. It will rest on the vanity but that will just provide extra support.

Also, if you’re interested - someone here on Houzz made a somewhat similar looking type of vanity for her master bathroom. Instead of one piece - it looks like a stone floating vanity - but has a vessel sink instead of an integrated one. Costs A LOT less. I personally am not a huge fan of vessel sinks - and woukd prefer one that looks like the ones you posted - but it did turn out nice. Her contractor built the vanity out of CBU - and then used 24x48 tiles to cover it.

If you are interested in the above post, I will try to find it. let me know.

If you had one of these made (or found somehwere to purchase one), I’d love to see photos !
