They are big time hipbone bangers. Or, at least they are at my height. They might hit you elsewhere. But, they WILL hit you if you at all stand close to the sink to load the DW or wash veggies or other tasks that involve time spent at the sink.

I'm a huge fan of towel bars in the kitchen. My dishwasher is next to my sink, so I solved the "where does the hand towel for the sink go?" dilemma by using a big bar-like handle for my paneled dishwasher. Solved! :-)

As long as you make sure to avoid the hipbone contact area, I say go for it.

Nothing like leaning into a wet towel while you are working at the sink....to make you regret ever having drilled the mounting holes in your nice cabinetry.

Also, I don't want to cozy up to a damp towel while I'm working at the sink. A dry towel is just as easy to grab off a counter or other stash point (but is usually in the drawer because I never remember to take one out)--so a damp to wet towel is what I always have on the bar!

I love a sink bar! I have never had the issues that were brought up here in other responses. My problem is finding them when time comes to update!
