A main bathroom renovation is very disruptive to a household.
The mess, inconvenience and cost can be high but putting on those finishing touches and having that first shower is ohhhh so satisfying. Knowing that you have put the infrastructure in place to last another generation.
Demolishing the old and not quite finishing the job on the other hand can put an enormous strain on everyone. You have put in some effort but got distracted on the next job.
You would avoid putting your family through the angst but many in business do it to their employees and themselves.
Incomplete processes, gaps in capability, slow to implement, lack of investment and the list goes on.
Don’t be the cobbler who’s children have no shoes.
