Hello dear forum members,

I want to renovate the bathroom in my apartment from the 1960s.
As was common back then, the bathroom is very small (about 3.5m² (38 sq ft)) and unfortunately equipped with a combined mini bathtub and shower. I would like to replace this with a shower. Since all the connections and drains are located on one side, the layout is quite inconvenient given the small size (room depth only 2m (6.5 ft)), with the toilet and sink positioned next to each other. You would gain a lot more space for the shower (across the entire width) if the sink could be moved to the opposite side. Of course, this would require major renovations, meaning changes to the drainage and water supply.

I understand that a bathroom is a significant cost factor, but the prices I have encountered here in Berlin, where I live, have really been surprising. So far, I have contacted three companies, and all of them told me to budget €15,000 (!!) if I want to avoid any surprises. This sounds like an extremely high amount to me — the bathroom measures only 2m (6.5 ft) deep, 1.7m (5.6 ft) wide, and 2.7m (8.9 ft) high.

I have very little experience with this and wanted to ask here if such prices are typical.

Thanks in advance.

That will be the biggest cost driver—if it’s even possible with the drain (usually it’s not). Otherwise, the budget of 15,000 EUR is either just a rough estimate or you requested very high-end bathroom fixtures.

I also think that the "difficulty allowance for a small bathroom" has been included here.
There’s nothing you can do about it. You can usually only have this done by someone who was recommended by another person, like an independent tradesperson.

Let's consider the overall scope. We also have a small bathroom. I gutted it myself. That took many hours of work despite having good tools. Those hours need to be compensated. Then the walls have to be refinished, either by plastering or drywall installation.
A reasonably good-quality toilet bowl alone costs around 800€ (about $870), plus the matching seat for 160€ (about $175).
Sanitary fittings are heavily marked up in these projects.
On top of that, you have foreman fees, materials, and labor for the tiling.
Costs can easily reach 15,000€ (about $16,300).

Doing some of the work yourself can significantly reduce costs. However, you first need to find someone who will offer a much lower price.

15,000 easily add up.

A bathroom for 800€??? Where do you shop or what do you have the plumber bring?
Example: Duravit Vero toilet + soft-close seat = 550€
Duravit Vero 60cm (24 inches) washbasin + vanity unit + Steinberg single-lever mixer = 800€
Shower tray with installation frame (Kaldewei Conoflat 100x100cm (39x39 inches) + Kaldewei ESRII + drain fitting) = 900€
Shower enclosure 100x100cm (39x39 inches) own brand Megabad = 850€
Hand shower (30cm (12 inches)) with mixer faucet = 400€
Plus suitable small parts, so about 3,700€ materials for plumbing.

Then let’s take 10m² (108 sq ft) of tiles (easy to calculate) at 50€ each + finishing strips and materials = generously 1,500€.

That leaves about 10,000€ for the tradespeople rebuilding the bathroom. At a generous 100€ hourly wage, that’s 100 hours of work = 12.5 working days. Maybe some materials cost less.

And you want to tell me that 15,000€ is easily enough? If you think that’s relaxed for the tradespeople, then sure.

P.S. The plumbing prices are from the tradesperson.

The price doesn’t really shock me. After all, the inquiry was made without a detailed plan. Now we need to go into more detail.

The list from @nordanney is already helpful, but items like supply lines, drainage, bathroom radiator, screed, possible rewiring, pre-wall installation, and so on are missing. Above all, it’s unclear how the installation of supply lines and wastewater will be carried out.

So yes, without detailed planning, I find the mentioned €15,000 just as a rough estimate reasonable.
