Yes, I agree it looks bad, what would need doing to put it right, I got talk to them.later and I know they will say,.
1 it's under the tolitet so you can't see it.
2. That bits behind the plyth so you can see it.
No idea what they say about the floor and the rest.. they did Silicon around the floor some parts are okay but other areas it looks a mess.
In fact for the floor they will say it's because it wasn't level.
Any professional live near Nuneaton as we probably going to need a qoute to put this right.
