Shower leaks are sneaky. You don't see the water escaping, you just notice damp patches on the ceiling below, mould appearing on walls, or floor tiles coming loose. Water escapes through failed sealant, cracked shower trays, loose waste connections, or gaps in tile grout. In Sheffield's older conversions around Lenton, Radford, and Sneinton, shower trays installed directly onto floorboards without proper waterproofing often leak within a few years.

We detect and repair shower leaks using water tests, inspection cameras, and moisture detection. We identify whether the leak is from the tray, the waste connection, the tiles, or the screen seals. Once found, we fix it properly: reseal the tray, remake waste connections, regrout tiles, or replace failed components. We don't just silicone over everything and hope, we fix the root cause.

We operate across all Sheffield areas with same day service. No call-out fee. All shower leak repairs carry a 12-month guarantee.

Where Showers Leak From

Most shower leaks come from a few common failure points:

Shower tray seal

Silicone sealant around the tray edge fails and lets water seep underneath. It runs through gaps in the floor and drips through the ceiling below. The tray looks fine but water escapes every time you shower.

Waste connection

The trap under the shower tray works loose or the seal perishes. Water leaks from the waste pipe connection. Often the leak is slow and only shows up after months.

Cracked shower tray

Acrylic or stone resin trays crack if not supported properly. The crack lets water through. Cracks are sometimes visible, sometimes hidden under dirt or standing water.

Failed tile grout

Grout cracks and lets water penetrate behind tiles. It saturates the wall, rots the plasterboard, and escapes downward. Common where tiles meet the tray.

Shower door seals

Magnetic or rubber seals on shower doors perish and let water escape onto the bathroom floor. It seeps through gaps in the flooring and leaks through below.

How We Find Shower Leaks

We test systematically to identify exactly where water is escaping:

1

Inspect for obvious signs

We check sealant condition, look for cracks in the tray, test the tray for movement (poor support causes cracks), and inspect grout and tile condition.

2

Water test

We seal the waste, fill the tray with water, and mark the level. If the level drops without the waste open, the tray is leaking. If it holds, the leak is from the waste or seals.

3

Run the shower

We run the shower and watch underneath (if accessible) to see where water appears. We also check bathroom walls and floors for water escaping from door seals.

4

Moisture detection

We use moisture meters on walls and floors around the shower. High readings show where water is penetrating. Thermal cameras show damp areas.

5

Inspect the waste

We check under the tray (if accessible) or remove the trap cover to inspect the waste connection for leaks.

Common Shower Leak Repairs

Once we've found the leak, here's how we fix it:

Reseal the tray

We cut out old silicone, clean the joint thoroughly, and apply fresh sanitary-grade silicone. Proper sealing stops water escaping around the tray edge.

Replace the waste

We remove the shower tray (if removable), fit a new waste and trap with fresh seals, and test it under pressure. Secure waste connections don't leak.

Regrout tiles

We rake out failed grout, clean the joints, and apply fresh waterproof grout. We also reseal where tiles meet the tray.

Repair cracked trays

Small cracks in acrylic trays can be repaired with specialised filler and gelcoat. Large cracks or stone resin trays usually need replacing.

Common Questions

Got questions? Here's the quick answers.

How much does shower leak detection cost in Sheffield?

Detection costs £95-£140 (free with repair) across Sheffield and surrounding areas. Resealing costs £80-£130. Waste replacement costs £120-£200. Tile regrout and reseal costs £100-£180. Full tray replacement costs £250-£450.

How long does shower leak repair take?

Resealing takes within 2 hours plus 24 hours curing time before you can use the shower. Waste replacement takes 2-3 hours. Tray replacement takes 4-6 hours or a full day depending on access, whether you're in City Centre, West Bridgford, or Beeston.

Can I use my shower after you reseal it?

Not for 24 hours. Silicone needs time to cure properly. Use it too soon and the seal fails immediately. We'll tell you exactly when it's safe to use.

Will you need to remove the shower tray?

Only if the waste is leaking or the tray is cracked beyond repair. Most leaks are from sealant or grout and don't require removing the tray.

Why does my ceiling leak when I shower but not when I run the bath?

The shower leak is from spray water escaping through failed seals or grout. Bath water doesn't splash as much so it doesn't find the gaps. The leak is from the shower enclosure, not the plumbing.

Can silicone sealant be applied over old silicone?

No, new silicone won't stick to old silicone. We cut out all the old sealant, clean the joint with alcohol, let it dry, then apply fresh sealant. Shortcuts don't work.

My shower tray moves when I step in it, is that a problem?

Yes, movement means poor support underneath. This causes cracks in the tray and breaks the seal around the edge. We'll check the support and improve it if needed.

Can you fix my shower without removing tiles?

Most shower leaks are fixed without removing tiles. We reseal edges, replace wastes from below, or regrout existing tiles. We only remove tiles if they're loose or the tanking behind them has failed completely.

Is it worth repairing an old shower or should I replace it?

If the tray is sound and it's just sealant or waste leaks, repair it. If the tray is cracked, tiles are loose everywhere, or it's leaking from multiple points, replacement makes more sense. We'll advise honestly.
