Inspected by Peter Weddell, owner/operator of Qld Home Buyers Inspection Service and Queensland Building Inspection Service, QBIS.

A bath that is not properly installed for the use of a shower above it.

Incorrect installation of bath-shower 1

When installing a shower outlet above a bath, the wall tiles must extend into the side and rear lips to avoid seepage and rot to the walls and floor. Or in a two storey house, damage to the ceiling linings below.

Incorrect installation of bath-shower 2

Shower base in this photo has not been properly installed.

The shower base must be recessed into the walls, the wall tiles must extend into lips of both sides.

Incorrect installation of bath-shower 3

This photo shows leaking to the floor below. Although leaking has not caused significant rot at this stage. The bath above must be removed and refitted correctly to avoid further timber rot.


Both the bath and shower base would have to be removed then refitted and recessed into the walls to allow wall sheeting and tiles to extend into back and side lips of the bath.

Incorrect installation of bath-shower. Important notes:

  • Improper shower-bath installation, is usually caused by a DIY or tradespeople that lack experience.
  • It pays dividends to research anyone you are employing to carry out costly renovations, before employing them.
  • Otherwise you can be up for the cost of doing the renovation twice!
