I know this might seem like a basic topic, but we really aren’t skilled DIYers.
When it came to bathroom fixtures, the general contractor (GC) didn’t have the options we had in mind. So, we agreed to install the washbasins for the bathroom and toilet ourselves.
We found some online that we like. The washbasins come fully assembled, which is already a relief.
They include the basins themselves. The basins have holes drilled (according to European standard dimensions, it says), and that’s it.

And now we’re already overwhelmed again. What else do we need to buy?
The GC will handle the connections. Quote from the contract: the pipes such as drain pipes, hot and cold water, and 2 angle valves remain part of the contract.

You definitely need the drain fitting for the basin where the water flows out. Also, we probably need the pipes from the hole in the basin to the wall.
And we need a faucet.

Is there anything else we might need? Seals or gaskets? Oh, and we want to have it installed, not do it ourselves—unless installation is very simple.
Does the faucet come with the necessary connections to the angle valves?

Oops… looks like something got a bit mixed up. I was actually looking for something else when I came across these parts. For example, I like the idea of two wall brackets or the wall rail system from IKEA’s kitchen range, where you can simply hang kitchen cabinets. Alternatively, you could attach matching legs or runners to the bottom of your cabinet so that you don’t have to drill into the wall at all. In that case, even some mirror tape or something similar would be enough to hold it lightly against the wall, since it would stand on its own. But maybe you’ve already taken care of this.

I completely understand you. We're facing the same issue. We couldn't find fitting base cabinets and thought we’d either build something ourselves or buy some nice ones somewhere. The problem now is that the two sinks are spaced in a non-standard width. For example, if we took two base cabinets each 80cm (32 inches) wide, the cutout for the siphon at the back wouldn’t fit. And you wouldn’t want a 2cm (0.8 inch) gap between the two cabinets either. A large continuous cabinet under the two sinks also won’t work because the space for the siphon is already fixed and doesn’t match the sink width. So, we went to a carpenter and got several quotes. The cheapest was about 2,600 for a base cabinet roughly 170cm (67 inches) wide with two drawers... For that price, I could have had a very stylish one installed by the general contractor. We actually regret that now. And we still don’t have a cabinet :-/

How is it with the IKEA cabinets? In the middle of the cabinet, isn’t there already a cutout for the siphon? If the back is completely open, maybe you could build something nice there.

I just tried to find out. For the IKEA Godmorgon cabinets, I can’t say whether they have a siphon cutout or if they are completely open at the back. From the photos and illustrations in the assembly instructions, I assume that the top drawer is shorter overall. But their website is quite frustrating, and I can’t find anywhere how deep the drawers are.

I think many people here in the forum use them, so maybe someone with practical experience can help us.

The deeper Godmorgon cabinets come in widths of 80, 100, and 120cm (32, 39, and 47 inches), so you could probably make something work. Possibly add countertop-mounted sinks. I think you can manage the hoses for the angle valves even if you have to cover some extra distance. As for the siphon, that would need checking. There are variants that are longer or flatter, I’ve seen them before. If necessary, just ask at a hardware store.

Personally, I don’t like the IKEA countertop surfaces at all, but basically, you can put anything on top (kitchen worktops, custom-cut wooden boards from a carpenter—we bought ours as custom dimensions on eBay). Or you could choose one of IKEA’s undermount sinks if you like those.

Which IKEA cabinet do you want to put underneath? Or hang? Wouldn’t it be nicer if that countertop was just mounted freely on the wall? There are brackets available where you can even hang a towel over the bar.

Or you could have something made from steel frame legs, which is available cheaply and in many variations.

If the IKEA cabinet is narrower than the countertop, then the top is usually open as far as I know.

Basically, you could also hang kitchen wall cabinets from IKEA under the countertop, or one or two Metod drawer cabinets or the Godmorgon... the gray one in wide sizes looks really nice.

For this beautiful sink, you have to ask exactly which drain fits or check with the manufacturer.

We want to mount the narrow Godmorgon cabinet underneath. A free-hanging countertop on the wall isn’t really my thing. I know it’s trendy, but I don’t like seeing the siphon openly, even if it’s a fancy one. I prefer having a cabinet around it.

I already considered Metod, but even the narrow version at 37cm (15 inches) is too deep for our bathroom. Godmorgon is only 32cm (13 inches) deep. The countertop is cut to fit accordingly.

The sink has a standard 45mm (1.8 inch) drain. I hope I can use just about any drain with it. I’m a bit skeptical, but every sink I’ve seen so far has always specified 4.5cm (1.8 inches).

Good morning in gray here—I think it’s 100cm (40 inches) wide. I can give you the measurements or whatever you need. I don’t like the IKEA boards for this, so I got a 40mm (1.6 inch) plywood board and stained it dark; it cost about €50 and looks nice.

The Godmorgen unit is supposed to hang under this board, but in reality, I screwed it directly to the wall. The board rests on the left against the wall, and on the right, we have a metal bracket from the locksmith costing €40.

Godmorgen is open at the top, so you can use a space-saving siphon from any hardware store or similar, which works fine. My only concern was whether you’ll get the right connection for your stone basin; you’ll need to ask about that specifically.

We have Godmorgen in both bathrooms, and combined with other boards and materials, it doesn’t look like IKEA.

I quickly took a picture of it.

I have the Godmorgen in gray here, I believe it is 100cm (39 inches) wide. I can provide you with any measurements or details you need.

Is there space behind the drawers for the siphon? Or is it only open at the top so that you need a flat siphon?

The cabinet is open on top, so it doesn’t have a countertop. The top drawer doesn’t extend all the way to the wall because the siphon will be installed there. Ikea offers a space-saving siphon, but since you’re not using an Ikea sink, I would recommend getting a standard space-saving siphon from a supplier, such as Viega or another brand. However, you definitely need a space-saving siphon.

The cabinet is designed exactly for that purpose.

I think you want a depth of 32cm (13 inches); mine is about 49cm (19 inches).

My stone basin has standard drain dimensions, so that should not be an issue.
