10/12/20 - I am adding more information regarding this product. Unfortunately, I was not able to use the longer arm that the seller sent me as it is square and does not fit the original opening because the wall plate does not slide forward. I went ahead and purchased two other arms and am now waiting for them to be installed. In the meantime, I sent comments to the seller on 10/6 regarding new issues I have had with this product since the original issue of the shower arm. Now the knob that switches the valve from shower to tub and the wall plate are defective (see pictures).I purchased this shower/tub combination for my bathroom remodel which was completed on 8/29. The rotation knob that allows you to switch from shower to tub had a little cover on the bottom of it. That little cover has fallen off and now there is just an open hole. I was hoping I could get a replacement knob, but have not heard back from the seller (emailed them on 10/6). Bathroom remodels are very expensive, and honestly, I am very upset that I continue to have issues with this product. It looks very nice, but it has not held up well at all, and it's only been installed for about a month. I am also including a picture of the shower head arm plate that goes on the wall...as you can see it does not stay in place. I am very frustrated with this entire product. I am hopeful that the seller will respond since they were so responsive initially.Original comments below -We just finished remodeling our hall guest bathroom (see before and after pics) and love the way it turned out. We purchased this shower/tub combo and love the modern high end look it has. The pieces are all very sturdy and well made. My plumber commented how easy they were to install. I purchased the 8" shower head and had a question about swapping the arm to the one that comes with the 10" model and customer service was quick to respond! Will be sending me the longer arm. Thank you for your excellent quick resolution to my question. I will be remodeling my daughter's bathroom in a couple of weeks and will be purchasing another one of these (the 10" shower head though). Definitely highly recommend this product! Thank you :)
