Wanted to unblock the en suite shower in our new house, and usually I hate the use of any chemicals that are harsh (especially with children try to avoid at all costs).
However, I couldn’t get the drain unblocked, and finally gave in to buy some.
Followed the instructions (pour bottle slowly into drain), but as I was doing so (bottle nearly empty), a lot of the contents ‘regurgitated’ back out. Now half the shower tray has drain unblocker sitting there 
It states to leave for an hour followed by use of hot water.
I’m worried that the drain isn’t going to be any better, but now with the unblocker sitting there I’ve rendered it unusable.
Anyone had similar experience? Have I made a huge mess?
