Guest WC (1.65 sqm) and bathroom (4.88 sqm) renovation

HAa

For the guest WC, I would consider a small storage water heater, which also fits under a small sink and runs on 230 volts, for example the AEG 236 284. 5 liters of hot water is easily enough for 2x hand washing, and after a few minutes it is refilled again. At 70 euros for replacement, that's a no-brainer.

Hey, that's actually what we want to do, 5 liters flow-through, all clear. I had googled the device once and ended up with a lot of negative reviews at Hornbach. (I would have linked it here, but I have already received a warning about linking to commercial websites [very broad term!]). So I am throwing the following well-rated ones into the ring here that are also available promptly on the relevant Megabad page cc:
* AEG non-pressurized small storage heater Huz 5 Basis, 5l, 2kW, plug-ready, under-sink, EEK A, 222162
But here I will also research again based on the devices available in online shops.

You should definitely try a 160 bathtub sometime. I don’t think that’s really big, right?

But there are also sometimes 160x100 rectangular ones depending on the shop, so also apart from the asymmetrical space-saving bathtubs. (oh again: I would like to make the deeplink to the search mask in the shopping portal where this is preset, but you’re not allowed to, right, Admin? @others: what’s the status regarding Idealo deeplinks, are these allowed? I’d rather not step into a faux pas again)

However, these 160 bathtubs probably require some skill from the installer, or BUT we have to go for a 150, since the room is only 167 wide...

(also a tedious topic, we are still looking in the Cologne area for someone, the currently recommended one is hard to communicate with, we might have to look again. So if anyone knows an HVAC company in Cologne who could do our bathrooms and the other one on short notice, that would be possible)

I still don’t see a toilet in the main bathroom?? Leave the tub, on the plan above a large walk-in shower with a 100cm glass wall, then a large double washbasin and definitely a toilet. Look for seamless alternatives!

With sliding door to the bathroom (provided it is not a load-bearing wall), toilet, tub, and shower. The sink can still be moved around the corner, which leaves more space to the toilet. Instead of tub and shower, a large corner tub would also work.

If someone likes that, the room does not get bigger and everything feels cramped and tight. Simply do without the bathtub and design a large, friendly shower area. Ask yourself how often you have used the bathtub in the last three months and then ask if it is really needed. Just because you can somehow squeeze it around the corner does not mean it is also nice and practical.
With 5m2 you just have to make compromises.

In principle, I agree with you. But here we were talking about children (one and three years old). If anything, a bathtub is certainly very useful here.
