DIY GONE WRONG

When the Bath Gets Priority Over the House šŸ›šŸ 


I inspected a house today where the bath waste clearly won the argument with the floor joist.


To make room for the plumbing, an entire section of floor joist had been cut out. The solution? A true DIY masterpiece:


A short off-cut of timber


Sitting on a cinder block laid on its side (the weakest way to use it)


Carefully ā€œpackedā€ with broken asbestos base cladding for that extra touch of danger



If you’re wondering whether any of this is structurally sound, moisture-resistant, or safe — the short answer is no. The long answer is absolutely not.


Cutting structural members to install plumbing is never a ā€œjust wing itā€ situation. Proper trimming, load transfer, and fixings are needed — not a game of Asbestos Jenga under the bathroom.


This is exactly why pre-purchase inspections matter. What looks like a perfectly normal bathroom upstairs can be hiding some truly creative engineering underneath.


If you’d like your dream home checked for surprises like this (before you own them), you know where to find me.
