How to cut chrome neatly?

[HappyFace]

I have just had a shower fitted and the shower valve sits on a chrome plate (6in wide by 12in deep) flat to the wall. However it is slightly wonky (out by about 4mm) and it is the first thing my eyes are drawn to when I go in my bathroom. Rather than knock several tiles off the wall, dig out the plumbing etc etc, I thought I could get the chrome plate cut professionally. I am sure this would be a cheaper and less messy option. Only problem is I don't know who could cut the plate cleanly. It needs to have smooth edges and be polished as if new. Any ideas welcome. Thanks

It can be cut with a variety of toos or methods, from a plasma cutting torch to a high speed rotary tool or even a good hand with a hacksaw. Two problems with cutting chrome plated metals; the process can give off toxic fumes and the actual chrome plating is quite hard, thus requiring the special method suggested above. Additionally, as the piece now exists, the edges are also chrome plated (probably copper or brass underneath). Once the plating is cut, there's likely, sooner or later, to be flaking off of the chrome as the shower water or household cleansing chemicals corrode the base metal. This will continue, in my opinion, until the whole piece will have to be replaced. Having said that, best of luck!

Could the appearance be improved with sealant?

If you are anticipating removing the plate to have it cut why can't it be removed and then replaced in the correct position? Or am I missing the point somewhere?

is it possible to pack one side out to make the gap consistent and then apply mastic if necessary
i was thinking of the plastic shims used in upvc window installation that won,t corrode

The pipes to the taps have been cemented in place. The plate then slides over the three protuding tap bodies. Finally the tape heads are attached to the tap bodies. What makes it appear more wonky is the fact your eyes get drawn to the grout of the tiles nearby. Mastik or sealant wont help unfortunately. The easiest option is to cut the chrome plate squarish. My problem is finding out what profession would be able to cut it neatly and reapply the chrome. Where in the Yellow Pages would I start looking? Thanks
