Best Bath Salts and Soaks for Relaxing at Home in 2026
Epsom salt, Dead Sea salt and shower steamers compared on mineral type, pack size and fragrance — to help you choose the right soak for your bathroom, bath or no bath.
Bath salts split into two quite different products: unscented mineral soaks such as Epsom and Dead Sea salt, and fragranced bath products bought mainly for the scent. Distributing Care found the UK Best Sellers list is dominated by the first group, with one brand holding several of the top ten places on its own, so the real decision for most buyers is which mineral, in what quantity, and whether they have a bath to use it in at all.
The three products below are compared on mineral type, pack weight, added fragrance and how each is used. Two are 1 kg mineral soaks; the third is a shower steamer, included because a great many UK households — and most care settings — have a shower and no bath. Each pick came from the top ten of a single Amazon UK Best Sellers category, and every card carries its rank.
How we tested & chose
The shortlist came from the top ten of Amazon UK’s Best Sellers in Bath Additives, a list ranked by units sold rather than by search relevance or advertising spend. Distributing Care read each listing directly on 29 August 2026 to confirm mineral type, pack weight and whether fragrance is added, then set aside children’s bubble baths and duplicate Epsom listings so the three picks are genuinely different products.

Bath soaks are cosmetic products, not medicines, and Distributing Care makes no medical claims for them — the evidence that magnesium is absorbed through intact skin from an Epsom bath is limited. Take care getting in and out of the bath, keep the water comfortably warm rather than hot, and speak to a GP or pharmacist first if you have eczema, broken skin, diabetes or reduced sensation in your feet.

Frequently asked questions
Quick answers to what readers ask most about bath salts.
Do Epsom salt baths actually raise your magnesium levels?
The evidence is limited. Epsom salt is magnesium sulphate and dissolves readily in warm water, but good-quality studies showing meaningful magnesium absorption through intact skin are scarce. Most people use an Epsom bath because they find the warm soak itself comfortable, which is a perfectly reasonable reason to buy one, just not a proven nutritional one.
How much bath salt should you use in one bath?
Follow the instructions on the pack, which for 1 kg mineral soaks typically work out at roughly 250 to 500 g per standard bath, or two to four generous handfuls. Add the salts under running hot water so they dissolve fully, then top up with cold to a comfortable temperature before getting in.
What is the difference between Epsom salt and Dead Sea salt?
Epsom salt is magnesium sulphate, a single compound, and is the usual choice for a plain muscle soak. Dead Sea salt is a mixed mineral salt containing magnesium, potassium and calcium chlorides, and is generally sold for skin rather than for muscles. Dead Sea crystals are coarser and take longer to dissolve.
Are bath salts safe if you have sensitive skin or eczema?
Ask a GP or pharmacist first if you have eczema, psoriasis or any broken skin, because salt water can sting damaged skin and hot water can make itching worse. If you do use them, choose an unscented mineral salt rather than a fragranced soak, keep the water warm rather than hot, and rinse and moisturise afterwards.
Can you use bath salts if you only have a shower?
Not directly, because mineral soaks need a bath to work. Shower steamers are the shower equivalent: a scented tablet placed on the shower floor away from the direct stream, which fizzes in the steam. They are an aromatic product only and do not provide a mineral soak.
