ᐅ Styrofoam Shower Base Support – Is It Recommended?

We are getting a steel enamel bathtub that is to be installed in a polystyrene bath carrier—partly for insulation reasons and partly to reduce noise, as these tubs tend to resonate oddly without a carrier.

This was all coordinated with the plumber, but now he suddenly said he hasn’t installed one of these carriers in two years because some customers (apparently only after 1-2 years) complained that the carrier squeaks.
Great that he always brings up issues like this at the last minute, especially after he already submitted a quote for it.

We don’t actually see a problem here; we could also add felt or some kind of “slip film” (whatever that may be) in addition.

How have you solved this? Does anyone have experience using such a bath carrier? It should be one from Schedel.

I had to remove a shower tray that was already five years old because the polystyrene support underneath had given way, causing leaks. My current plumber only uses these steel frames as well but also adds wooden blocks for extra support...

This is how it was done for decades, using polystyrene insulation, and it worked. I wouldn’t allow any upcharging here. Installation as per the offer. Period.

Hello

I installed my bathtub using one of those polystyrene supports. The tub fits securely in the support. What could be squeaking? And what should settle?
You just need to make sure the floor is level before placing the bathtub support.

My plumber also said that this is nonsense.
He simply placed the shower tray on Ytong blocks that were cut to fit, and it holds perfectly.

Hmm – I actually don’t want to use Ytong in the sanitary areas anymore. It tends to become somewhat "pastelike" in consistency when it is exposed to moisture for an extended period...
