Thermostat valves: meaningful?

Hello everyone,

what is the general opinion here in the forum about thermostatic valves for the shower?

I have encountered something like this occasionally in hotels and actually found it quite pleasant. But I am a bit skeptical regarding susceptibility to errors / defects.

The whole thing is to be installed in the three rented apartments in the house.

Looking forward to your opinions!

We used to have only single-lever mixers in rental apartments, and now in the house there is a thermostat in the shower. I find this thing extremely practical. In the morning I go to the shower, turn just one knob, and after 2 seconds (circulation) I have water exactly as warm as I want it. Without having to first turn it all the way hot and then adjust back or search for my comfort temperature every day. They are certainly not necessary, but they do bring comfort and are not more expensive than a classic mixer - the design version is usually what determines the price.
Everyone can set the stop for "38 degrees" or the comfort temperature as they wish and then always has a defined stop point.

With circulation, this may not be so important, but the longer the supply line and the more consumers are used on the line at the same time (pressure and temperature fluctuations), the more useful I find these devices.

I don’t know if they are much more prone to defects.

By the way, we have foregone a thermostat in the bathtub. However, the single-lever mixer used was not cheaper, the bathtub thermostat looked ugly, and you let in so much water in the bathtub anyway that you can readjust if it’s too cold or too warm.

Our guys really wanted a thermostat valve. So be it. We are installing one because we liked the design of the valve. For me, one rotary valve each for "cold" and "hot" is sufficient.

We have a thermostat in the current rental apartment and it is definitely practical. Especially when washing our daughter's hair, I am very glad that the water doesn’t suddenly get warmer or colder or that you have to fiddle around for ages to get the right temperature. In the house, we only have a thermostat in the main bathroom shower. We were told that they should be used regularly in order not to become prone to malfunctions. That is why we have refrained from installing one in the second bathroom.

We also have them in the showers and I find it very pleasant. However, one was already broken after 2 months... Maybe a coincidence.

Unfortunately quite prone. In a private single-family house fine by me. But not in a rental apartment. Unless [München beste Lage und absolute Luxusausstattung]. Know a hotel that has some. After two years almost no longer operable...
