Product Reviews

Rated 1 out of 5 by from Disappointed with this product I'm a DIY'er, engineer. I've installed a number of Grohe products, including shower valves. I've always been impressed with the quality - this Grohe Flex is a different beast. It looks very simple, however there are no instructions included - none - nada. I did find a Grohe produced video on you-tube. In the video it shows that you mount 2x4's horzontally across the studs. The Flex has mounting holes - both in the front and back. You can't use the rear holes in a 2x4 wall. If you use the front holes - the 2x4 supports interfere with the shower/tub outlets. You can see this in the first picture. The 'mounting ears' are about 1/2" long - that means the fastening screws are about 1/4" from the egde of the 2X4. Lastly, if you want your drop eared ell to be just through the cement board - you need to use soft copper to bring it forward - see 2nd picture. All in all this is a nightmare to work with. You'll spend a lot of extra time getting this to work out. Would not purchase again.
