Bathroom, finished?

So our long awaited, much anticipated bathroom is finished.  At first glance it is fabulous.  The bath is a dream and I love the colour the room is painted.  Unfortunately it doesn't bear up to close inspection.  The finish is really quite poor - the walls are bobbly, the sealant is messy and the paint job is really bad.  The guy who did it, did a great job on demolishing the old bathroom and the plumbing of the new, but his lack of attention to detail has really disappointed me, and made me rather sad.
