How to Diagnose a Shower Base Leak: A Step By Step Guide for Newcastle Homes
How to Diagnose a Shower Base Leak, A Step By Step Guide for Newcastle Homes
At Leak Hunters, many of the leaks we investigate in Newcastle homes come directly from the shower base. These leaks can be tricky to diagnose because the problem often hides beneath the tiles or behind the walls. A shower base leak may start small, but it can quickly spread into the floor structure, subfloor, or adjoining rooms if left untreated.
If you want to understand whether your shower base is leaking, this step by step guide will help you identify the warning signs and determine when you need professional assistance.
What Causes a Shower Base Leak
Before you start diagnosing the problem, it helps to understand the most common causes of shower base leaks.
- Cracked or deteriorated grout
- Damaged silicone around the edges
- Movement in the shower base or tiles
- A failed waterproofing membrane
- Plumbing leaks beneath the shower
- Incorrect installation during construction
These issues often develop gradually, so early detection is key.
Step 1: Check for Visible Cracks or Gaps
Begin by inspecting the shower base and surrounding area. Look for cracks in the tiles, loose grout, gaps around the edges, or missing silicone. Even a small break in the surface can allow water to escape underneath. If the silicone is peeling, mouldy, or lifting, it is no longer sealing the area properly.
Step 2: Look for Moisture Around the Outside of the Shower
Carefully check the floor or walls just outside the shower. If you notice dampness, bubbles in the paint, swollen skirting boards, or soft plaster, this can indicate a shower base leak. Water often travels outward before becoming visible.
Step 3: Examine the Ceiling Underneath the Bathroom
For two storey Newcastle homes, the ceiling below the bathroom can reveal a lot. Water stains, sagging plaster, or moisture marks are strong indicators that water is escaping from the shower base or surrounding area. Even a faint stain is worth investigating.
Step 4: Check for Loose or Hollow Tiles
Tap the tiles around the shower base. If they sound hollow or feel loose, water may have weakened the adhesive underneath. This is a common sign of a shower base leak and often indicates that the waterproofing layer has failed.
Step 5: Run a Controlled Water Test
A simple water test can help identify whether the shower base is the source of the leak.
Here is how to do it safely:
- Dry the entire shower area.
- Plug the drain.
- Fill the base with a small amount of water, just enough to cover the surface.
- Wait and see if water appears outside the shower, in adjoining rooms, or downstairs.
If water appears, the base is likely leaking. If not, the leak may be coming from plumbing or wall areas instead.
Step 6: Check the Shower Screen and Edges
Sometimes water escapes not through the base itself but through unsealed edges or gaps around the screen. Look carefully at the bottom of the shower screen and the corners. If water is pooling or escaping after every shower, this could be the issue.
When a Shower Base Leak Requires Professional Detection
While homeowners can perform basic checks, many shower base leaks are hidden beneath tiles or waterproofing layers. These cannot be diagnosed accurately without professional tools. Here is when you should call Leak Hunters.
- Damage is appearing in multiple areas
- You cannot find the source of the leak
- The shower base moves when stepped on
- The leak returns after DIY repairs
- There is mould or musty odour
- You want to avoid unnecessary tile removal
