Improper installation of bath-shower, in Camp Hill, an Eastern suburb of Brisbane,

Improper installation of bath-shower. Peter Weddell, owner/operator of Qld Home Buyers Inspection Service and Queensland Building Inspection Service, QBIS.

Improper installation of bath with a shower above


This bath has not been properly installed for a shower outlet above it.


  • A platform shelf has been created around the bath that will allow seepage and rot to occur.
  • Impossible to keep sealed, even if water-proofing has been fitted to its perimeter
  • Water-proofing is most likely to crack, from different rates of expansion and contraction between the different materials.

Improper bath and shower installation

Another improperly fitted bath with shower outlet above in a unit.

Water will seep through the shelf created between the bath and wall, which will cause rot to floor and walls.

Improper installation of a bath-shower.


Wall tiles must extend into the perimeter lip of the bath, to achieve this

  • Wall tiles, sheeting and bath must be removed.
  • Recess the bath into the walls. If necessary build walls out to achieve this.
  • Apply approved waterproofing, where necessary.
  • Resheet and fit tiles down into all edge lips of the bath.

This is a practical long term method of installation.
