ᐅ Rough-in plumbing for bathtub

Hello,
we are currently planning our new bathroom.
This bathroom will only include a washbasin, toilet, and shower.
We are skipping a bathtub because we don’t need one,
but we would like to have the installation prepared in case a future buyer wants a bathtub.
My question is:
If you prepare the rough-in plumbing for a bathtub installation later on,
how does that typically look?
Is everything concealed behind the tiles, or will water supply and drainage be visible from the outside?
And what about the underfloor heating?
Best regards, Gisela

Hello,

As mentioned above, under a bathtub, the underfloor heating is usually omitted, and the tub is even installed directly on the unfinished subfloor without screed.

Therefore, I would recommend either installing a fully functional bathtub or leaving it out entirely.

I don’t think it’s necessary to consider a potential buyer’s preferences— the likelihood that they would want exactly the same size bathtub you might be preparing for now is very low.

Regards,

Dirk

Thank you for your opinions.
We have now decided to completely forgo the bathtub and create a shower-only bathroom.
Best regards, Gisela

Hello Gisela,
it is definitely possible to install bathtub outlets concealed without causing hygiene issues due to water stagnation in the pipes.


The drinking water pipes must be installed in a serial or ring circuit system, for which special wall plates are required. These wall plates, for example at your bathtub connection, ensure that the pipe system is fully flushed whenever water is drawn.

Of course, these pipe systems are available for all common pipe materials and are now standard practice.

Now regarding making your bathtub connections invisible: the simplest method is to have the connections extend about 5mm (0.2 inches) beyond the tiles and cover them with a rosette and blind plug.

Completely invisible connections remain capped and hidden under the tile. After the rough installation, take some photos of the bathtub connections to be concealed and measure them precisely. When selling the house, all installation details, pipe layout plans, etc. are usually handed over anyway.

For example, after my renovation, I photographed all pipe installations with a measuring tape laid on top. From my own experience, I once drilled into a water pipe that I had installed four years earlier. This would not have happened if I had taken the time to photograph and measure everything. With today’s digital photography and storage, this costs only a few cents.
