Bathrooms collect more moisture than any other room, and in winter the steam from a shower can sit on cold walls and windows long after you have finished. A dehumidifier pulls some of that water out of the air. For a small bathroom there are three types: no-plug moisture absorbers that use crystals or tablets, mini electric dehumidifiers that collect a few hundred millilitres a day, and compressor dehumidifiers that remove several litres a day and suit a larger bathroom or a bathroom next to a bedroom. This guide compares all three, with extraction, tank size, noise and room size taken from each Amazon UK listing. If you are trying to dry clothes indoors, see our dehumidifier for drying clothes guide. We found 9 bathroom dehumidifiers and moisture absorbers in stock on Amazon UK with a live buy-box price when we checked on 27 October 2026.

Other bathroom dehumidifiers worth a look

Absorber, mini or compressor: which do you need?
Moisture absorbers such as the UniBond AERO 360 (£12.00) and Pro Breeze Osmo (£20.99) need no plug, so they are silent and can sit anywhere. They collect moisture slowly, over weeks rather than hours, and suit a small bathroom with a mild condensation problem.
Mini Peltier dehumidifiers such as the NETTA (£29.99), EasyAcc 1200ml (£39.99) and BLACK+DECKER (£31.80) collect a few hundred millilitres a day according to their listings, are light and quiet, and need a safe place to plug in. The EasyAcc bathroom model (£49.99) quotes up to 1300ml a day.
Compressor dehumidifiers such as the Devola 8L (£99.99) and COMFEE 10L (£74.99) remove litres rather than millilitres a day and suit a large bathroom, an en suite next to a bedroom or a damp flat. They are bigger, cost more and use more power.
What to look for in a bathroom dehumidifier
Extraction rate. Listings quote millilitres or litres per day, usually measured in warm, very humid test conditions, so expect less in a cold bathroom.
Tank and auto shut-off. A bigger tank means less emptying. Every electric model here says it switches off when the tank is full.
Power and plugs. Many UK bathrooms have no standard socket. Check where you can safely plug an electric model in, follow the manufacturer's instructions, or choose a no-plug absorber.
Cold rooms. EasyAcc says its bathroom model works down to 15°C; most mini dehumidifiers do not state a minimum.
Noise. Peltier minis and absorbers are quiet; compressor models are louder, though COMFEE quotes 36dB in sleep mode.
Ventilation first. A dehumidifier helps, but an extractor fan and opening a window after a shower remove steam at the source.
How we chose these picks
We only included products that were in stock on Amazon UK with a single live buy-box price in pounds when we checked on 27 October 2026, read with a UK delivery address. We skipped listings showing low stock, no stock line or unclear details, and we avoided repeating products already featured in our other guides. Specs in the comparison table come from each product's Amazon UK listing, and a dash means the listing does not state that detail. Descriptions are based on what each listing says; we have not tested these products ourselves, and we have not used star ratings or review counts.

Frequently asked questions
Do dehumidifiers work in bathrooms?
Yes, they remove moisture from the air, but how much depends on the type. Listings for mini dehumidifiers in this guide quote 250ml to 1300ml a day, while compressor models quote 8 to 10 litres a day. Use one alongside an extractor fan or an open window after showers.
Can you keep a dehumidifier in the bathroom?
Yes. No-plug absorbers such as the UniBond AERO 360 and Pro Breeze Osmo can stay in the bathroom all the time. For electric models, check you have a safe place to plug them in, as many UK bathrooms do not have standard sockets, and follow the manufacturer's instructions.
How big a dehumidifier do I need for a bathroom?
For a small bathroom with light condensation, a mini dehumidifier or absorber is usually enough. For a large or very damp bathroom, or an en suite that affects a bedroom, a compressor model such as the 8L/day Devola or 10L/day COMFEE removes far more water a day, according to their listings.
Are bathroom dehumidifiers worth it?
They can be if condensation lingers after showers even with the fan on. A no-plug absorber costs from £12.00 in this guide, while electric models remove more water but need a safe socket. Improving ventilation should come first.
