What is there now? Could you replace the doors?

Consider the feasibility of moving something that length through your home, not just the cabinet, also the countertop. After proper framing of the wall, individual cabinets are mounted such that they appear to be a single run. This allows you to customize each section (drawers) for your individual needs.

Any local cabinet design place can put together something half that cost. If half that cost and quality is what you want. Heck, it can be done for just over 1K, if that’s the quality you want. But you don’t get 6K quality for 1K.

Can you use 2 - 42" vanities?

We were very surprised at the relative affordability of hiring a custom cabinet builder. We looked at Shiloh cabinets and we liked those too, but in the end we hired a cabinet builder.

The cost will depend a lot on where you live. We are in the Gulf South just outside Houston where labor costs are relatively low. The man I hired built us a 94” vanity (paint grade maple), a 8’ x 4’ linen/storage cabinet with drawers and pull-out laundry (clear alder to be stained), a 3’ wide over the toilet cabinet in the WC (paint grade maple) and some clear alder floating shelves for 8k. But to that you need to add the costs of painting and staining. I can’t tell you that number because we painted the whole downstairs when the bathroom was done so those costs were all lumped together.

If you go with a cabinet company, such as Shiloh and there are many others, the vanity will come already painted or stained, so you don’t have that added cost.
