Bath · Bath Bombs
Some bath bombs are a light show. Big Blue is a place. Sea salt, lemon oil and real strands of seaweed turn your tub into a calm, mineral-rich stretch of ocean — the soak to run when you need to switch off, not switch on.
Why it worksSea salt that softens the water
Sea salt is the backbone of this one. It dissolves through the water to leave skin feeling smooth and soothed, in the way a swim in the sea does — without the sand. It is the reason Big Blue is the bath bomb people reach for after a long day on their feet.

The surpriseYes, that is real seaweed
Strands of seaweed float out as the bomb fizzes, releasing a fresh, briny, unmistakably coastal scent. They are easy to scoop out at the end, and they are what gives the water its deep, layered blue rather than a flat colour.
The scentBright lemon over sea air
Lemon oil lifts the whole thing, cutting through the salt-and-seaweed base with something clean and citrusy. The result smells like a coastline in the morning — fresh, cool and open.
Good to knowA slow fizz, not a fast one
Big Blue takes its time dissolving, which is part of the appeal. Drop it in as the tub fills, let the salt disperse fully, and give yourself twenty unhurried minutes. This one rewards patience.
Run the bath. Bring the ocean.
