Signs you need blocked bath & shower help
- Water stays in the shower tray after you finish
- The bath takes a long time to empty
- Gurgling from the plughole
- A musty smell from the waste
Blocked Bath & Shower: what the job involves
A blocked bath or shower leaves you standing in water. Hair and soap are the usual causes, because they bind together in the trap. Over time, that clump grows until water can barely get past. Shower trays and wet rooms suffer most, since their traps are small and shallow.
The engineer removes the waste cover and clears the trap first. If the blockage sits further along, they use a small drain snake, since it bends through the pipe. They also check where the bath waste joins the main drain, as that is another spot where hair collects. Finally, they fill and empty the bath or run the shower to check the flow.
A hair catcher over the plughole stops most of this happening. Clearing it every few days takes seconds. Pouring boiling water down the drain can soften soap build-up. However, it will not shift a clump of hair, so that still needs pulling out.
How the job goes
- 1. Clear the trap The engineer removes the waste cover and pulls out the hair and soap.
- 2. Clear the pipe They use a drain snake to clear anything further along the waste pipe.
- 3. Test the flow They fill and drain the bath or run the shower to check it empties freely.
Typical costs
UK price guides put bath and shower unblocking at about £30 to £75 outside London (Fantastic Services, 2026). MyJobQuote puts a bath or sink job at about £50 to £70. A blockage in the main drain costs more. These are typical ranges, and you can ask your engineer to confirm the price before they start.
Around Wolverhampton
Many homes around Wolverhampton have added a shower or wet room to an older bathroom. Because those waste pipes often run a long way to reach the old soil stack, they have less fall. As a result, hair and soap settle more easily. If someone added your shower later, mention it in your request.
Blocked Bath & Shower: frequently asked questions
How do I stop my shower blocking?
Fit a hair catcher over the plughole and clear it every few days. Rinse the tray after each shower, because that washes soap down. A kettle of hot water once a week also helps shift soap build-up.
Is a slow bath a sign of a bigger problem?
Usually not, because most slow baths just have hair in the trap. However, if the toilet and sink are slow too, the main drain may have a blockage. In that case, the engineer checks the drain outside.
Can an engineer unblock a wet room drain?
Yes. Because wet room drains have a removable grate and trap, the engineer can reach the blockage from above. They then clear the pipe beyond it if needed.
How long does it take?
A hair clump near the plughole is usually quicker to clear than a blockage further down a long waste pipe. The engineer tells you how long it should take once they see it.
