Fitting a larger shower in the floor plan - Which size to choose?

Variant 4: the storage cabinet replaced by a "worktop" of 60x35, for putting down stuff and makeup. The arrangement opposite Variant 3 is a bit different.

I notice that I would like to have a 100x100 shower, but this clogs up the room even more than a somewhat smaller shower. 90x90 is the more sensible option for the shower. Depending on the location, it can become a 90x100.

A washbasin 90 wide is probably really sufficient for washing. I still have to create a makeup area, possibly simply at the washbasin with the help of a mirrored cabinet (I would prefer just a mirror without a cabinet, but that costs a lot of practical usable space).

Have I missed something important? Yes, now I see it myself. In Variant 4, there is not enough space between the washbasin and the makeup area at the bottom of the plan.

A washbasin 90 cm wide is probably really sufficient for washing. I still need to create a makeup area, possibly simply at the WT with the help of a mirror cabinet (I would prefer just a mirror without a cabinet, but that costs a lot of practical storage space).

I know a bathroom where the shower cabin is opposite the door. It is a glass cabin, so on both sides. If you find that too open, you could make the middle frosted.

For the washbasin, I would take a worktop from wall to wall and a washbasin on it. There are already inexpensive ones that look nice. Underneath, an Ikea cabinet, as Kerstin already mentioned.

Personally, I would not place the washbasin in the center but offset to the side — then you have space on the other side for placing things or decorating or applying makeup. Personally, I would have the problem of having the drawers directly under the washbasin, i.e., where I stand. Because when you pull out the drawer, you have to contort yourself a bit or step to the side. We have everything asymmetrical on 160 cm width: washbasin on the left, drawer cabinet on the right.

How you arrange it depends on you. With a width of 180 cm, it would be advisable to have the drawer cabinet on the side, with shelves for towels under the washbasin. I would also base that on whether you need to sit while applying makeup, so possibly have a stool as well. At least with asymmetry, you would have space for 2 people next to each other.

I briefly experimented with a rounded quarter-circle shower as a substitute. But I didn’t like it that much, although of course it saves a little more space than a square one.

In the shower, you only need two corners (diagonally opposite), if you want to stand "crosswise" in an 80 cm shower sometimes. So basically against bumped elbows. You don’t "need" the fourth corner in the shower; it’s more useful outside when it’s gone.

You don’t need to have much within easy reach at the sink itself. Soap, preferably also the toothbrush and a towel for drying. Just the things truly used daily. If makeup + mirror were also there, that would be practical.

I don’t count the toothpaste tube and hairbrush as part of the washbasin size, but rather on a shelf above, same for everyday makeup stuff. Special occasion makeup stuff goes in a cabinet next to the mirror or something. For the washbasin width itself, just the basin, and beside it, if not within splash range, towels lying down. From that I conclude that 120 cm is already generously wide. Toothbrush placement is a matter of taste or habit, whether standing above or behind the basin.

From everything you do differently, correspondingly different measurements follow.

I wanted to update you on the status: from the plumber I found out that all my constructions with the shower in the corner and wall etc. are quite costly because of two sides of glass with a door, building and tiling the wall etc. I have then returned to the idea already drawn in the sales plan: on the left side a shower of 180x90 with a glass panel of 120 as a partition. Unfortunately, the window has a sill height of 80, so nothing can be installed under the window there. Then there is space to the right of the window for a washbasin of 80cm. That's it, shower on the left, washbasin on the right. I will only do the door differently: either open outwards or a sliding door. Thanks for your tips, the shower question is solved by installing an extra large shower.

Just a quick question about the shower: there will be a shower tray of 90x180 with an open entry from the side. This results from the glass partition of 120, leaving 60cm to step in. I can now install the shower head or faucet on the short side "in front" or on the long side. The latter would have the advantage that I have more space to the right and left, the other would probably splash less outside. I assume that, but I'm not sure. That's why I'm asking you: where is the best place to install the shower?

We chose 150 x 100 cm and 120 x 100 cm.
