Elsewhere, it looks like there are small amounts of plastic, but most of the construction is metal and it feels very solid. Hansgrohe is a popular brand, and you should be able to find it in local kitchen and bath or plumbing stores. I highly recommend you look at it in person before ordering online. We had one in the master bath shower in our last house for 5 years and had no problems with it. We put one in a tub/shower combo in the kids' bath in our new house about a year ago and DH and I are showering in there until the master bath can be remodeled. We plan to put the HG in the walk-in shower in our new master bath too - love that wallbar. Onelady, I know the wallbar can be used with a tub spout, not sure about the rainhead, although it should be possible with the right controls - check with a local store. For a shower only, you need the wallbar and shower head (sold as a set or separately), a wall outlet (at least 3 styles available), the rough valve, and the valve trim. The trim comes in lots of different styles to coordinate with the HG sink faucets. I prefer the Thermobalance II or III trim because it lets you control the temperature and pressure separately. We had the less expensive pressure balance valve and trim in our last house and it worked well (all our prior showers worked that way), but now we like to just set our favorite temperature rather than adjusting it each shower (you get spoiled once you have the separate controls, but you will never miss it if you have never had it). For a shower/tub combo, you need a valve & trim with a diverter built in, the tub spout, plus the items listed above.

Pressure balance is what you want I can’t see a thermostat being good in a guest shower and if you kids are too young to set the water temp they pobably should not be in there alone.You could get these I use them in my guest bath for my grand kids at the sink for washing hands and brushing teeth. The lights tell them when the temp. is right that is when it is green I haven’t need the tub and shower yet.

Wow, that is a lot of water. Didn’t realize that would use so much. We wanted this for a bathroom near our pool, if several kids wanted to rinse off at the same time. We will rethink that! Thank you for the info.

All my life I've used a handheld shower and I love it. But I'm doing a bathroom reno and when I was at a showroom they had a lot of fixed shower head + handheld combos. I'm wondering what the benefits are of having both? The handheld can function as a fixed showerhead already. I'm thinking it'd have these benefits: I can have the fixed showerhead on the wider spray option, and then the handheld on a more concentrated spray. Then I don't need to keep toggling between settings on the handheld. The fixed head would be in the exact position I like, compared to the handheld where I need to place it back in the holder and twist it til I'm happy. The question is are those worth the extra hassle of needing to use the diverter to switch between them constantly. The Delta In2ition 2-in-1 with the magnet looks like an interesting option, but the reviews about the magnet sometimes failing would make me paranoid. Thanks!
