Question: what is the diameter of the bar?
Document: we thought we were only ordering the bar but was pleasently surprised when the complete unit arrived. It is perfect for my in laws shower!! !
low quality plastic shower head that leaks , locking mechanism doesnt clamp down tightly on the bar so the water pressure will move the shower head around...very dissatisfied.
works good, looks ok but cheep & it was cheep. Buy it if you like cheep! If cheep is ok it works good.
we have this one now since 4 years. It was quite ok for the first 2 years but it started to leak on the head and these days i'd call it splashing now. it also sometimes hard to loose and adjust due to scale. Need to get it replaced with a new one. If you looking for one which does not need to last forever, this one is 'just ok' for its price i think.
was exactly what i wanted. I'm short (5'3&#34;) & my husband is a little taller (5'10&#34;). so he needs the shower head up high & I need it a bit lower.
total plastic junk, the shower head adjustment will not hold the head in any position. do not waste your time very disappointed.
low quality all plastic,the shower head adjustment will not hold the head does not lock in position,don't waste your money-not worth it
When it arrived, I was really disappointed. Didn't want to go to the trouble of drilling into tile and ruining them. I did it anyway, and it seems to be standing the test of time. It doesn't look like plastic when it's mounted and the only problem is the knurled screw for tightening the vertical height. It's tough to turn and doesn't really lock. However, you don't use this thing like a trombone, so once it's set, it is quite perfect.
We had just installed a walk-in shower and were dissatisfied with the shower head that came with it. We had used a sliding shower on our cruises in the past and had really enjoyed them. When we ordered our Duro-Med sliding shower we hoped it would be as enjoyable - and we weren't disappointed. It is such a pleasure showering with this unit. It works equally as well when we are standing or seated. It is easy to install and even easier to use.
We got this out of the packaging before noticing that the shiny finish was chipped off near the top. Amazon took it back with no problem, but I'm glad there was a factory default because the quality of it was not great and I would have had to pay to send it back because I didn't like it. I bought it for a very short elderly friend and the concept of sliding the shower head lower seemed great, but  you can't tell quality from an online ad.
Answer: no
