ᐅ Question about Renovation (Concealed Installation) of an Apartment in a Residential Building

Hello,

we are currently considering renovating an apartment in a large residential building.

During the renovation, we will need to adjust some water pipes because the bathtub is going to be replaced with a shower. The toilet will get a concealed cistern, and the water pipes in the kitchen currently come out of the wall above the sink; of course, these will need to be rerouted downwards.

Is it usually straightforward to make such changes to concealed water pipes, or do we need to consult the building management first?

The apartment was inherited by my grandmother and is planned to be sold. Before selling, we would like to fully renovate it to achieve a higher resale value.

Of course, we will still talk to the building management, but maybe someone here knows how this is typically handled?

Best regards
Specki

It is rare to have a shut-off device for the entire piping system within the apartment itself.

I believe this is not that uncommon, since the water meter is located there, and two valves are installed to replace it.

Unfortunately, I didn’t check under the kitchen sink, but the bathroom looks like in the photo.

So from the water meter onward, I could continue the installation as I need. That would be great 🙂

Toilet in the bathroom with the lid open, heavily soiled and damaged.

What material is the entire house made of? With brick, embedding it under the plaster is probably possible. However, with precast reinforced concrete elements, I would advise against it. That would interfere with the structural integrity of the house. There are also regulations in the standards regarding chases in masonry.

Well, it would also be possible to chase the screed and lay pipes there. There are no limits to what you can imagine. Besides, the old pipes also need to be placed somewhere.
For example, with the toilet, you remove the old pipe and lay the new one in the same place.

You definitely can’t install everything however you want. Downpipes and the slope of the pipes will set clear limitations.

You should also keep in mind that a potential buyer might see DIY work as a reduction in value rather than an increase. After all, they don’t know your skills, and even if they do, obtaining insurance coverage can be difficult.

Looking further: Does an apartment block even attract buyers who want a clean, modernly renovated apartment and are willing to pay the full price but are still okay with an apartment block?
The key point is location — that’s always what matters.
I don’t want to rely on stereotypes, but a house in a working-class neighborhood aiming for affluent buyers will probably be difficult to sell at its true value.
Some won’t want to live there, and others won’t want to pay that value 🙂

Generally, I would say that renovations going beneath the plaster layer are not worth it.
Mostly, new paint, new tiles, etc., will make the biggest difference. I would only do anything else if absolutely necessary.
A new owner might think the same — why renew and pay if the old parts would have lasted another 10 years or more?
