Bottle Traps
Sort by:
Bottle traps are the curved fitting under your basin that holds a small amount of water, sealing the waste pipe.
Perfect for bathrooms, en-suites and cloakrooms, particularly with wall hung basins and pedestal-free setups where the pipework is on show. That water seal keeps drain odours out of the room, and a matching finish turns an exposed waste pipe into part of the design rather than something to hide.
Bathroom Mountain offers bottle traps in round, square and traditional styles, in chrome, matt black, brushed brass and white plastic. Solid brass versions are heavier and more durable for visible pipework, while lightweight plastic suits a budget fit inside a vanity unit, and there's a waterless option too. Fitting is manageable if you can reach the pipework comfortably, with a plumber worth calling where access is tight. Unscrewing the lower cup every few months to clear hair and soap keeps everything draining freely.
As a leading UK bathroom retailer, Bathroom Mountain offers affordable and quality bottle traps backed by our Price Match Promise, fast next-day UK delivery options and an Excellent Trustpilot rating, so you can buy with confidence.
What Is A Bottle Trap?
A bottle trap is the curved fitting under your basin that holds a small amount of water in its body. That water seal is what blocks drain odours from rising back up into the bathroom, while still letting waste water flow away.
What's The Difference Between A Bottle Trap And A P-Trap?
A bottle trap is a compact cylindrical unit that sits directly under the waste, making it neater and better suited to visible pipework. A P-trap is a curved pipe shape, usually hidden inside a vanity unit or behind a pedestal, and it typically handles flow slightly better.
Which Finish Should I Choose For A Bottle Trap?
Match the bottle trap to your tap and waste finish so it blends in rather than standing out. Chrome is the most common and matches most bathrooms, matt black suits modern schemes, and brushed brass pairs with warmer fittings and traditional taps.
Does The Shape Matter, Round Or Square?
Round and square bottle traps work identically. Round suits most basins and traditional taps, while square lines up better with angular basins, square waste fittings, and modern tiling.
Is A Brass Bottle Trap Better Than A Plastic One?
Solid brass bottle traps are heavier, more durable, and better looking where the pipework is on display. Plastic traps cost less and work perfectly well when hidden inside a vanity unit, so choose based on whether yours will actually be seen.
Can I Fit A Bottle Trap Myself?
Fitting a bottle trap is a straightforward DIY job if you're comfortable with basic plumbing and can access the pipework under the basin. If the space is awkward or you're not confident with waste connections, a plumber will get it sealed properly first time.
How Do I Keep A Bottle Trap Draining Freely?
Unscrew the lower cup every few months and clear out the hair and soap residue that collects inside. Catching it early keeps the water flowing as it should and saves a bigger job later on.
How to Choose Bottle Traps for Your Bathroom?
To choose bottle traps for your bathroom, first check whether the pipework under your basin will be visible or hidden, since that decides whether a brass or plastic trap makes more sense. Then pick round, square, or traditional to match your basin shape, and match the finish to your taps and waste. Order from Bathroom Mountain for great value on bathroom fittings with fast UK delivery.
