Small-batch, curated by hand with premium New Zealand ingredients — for the everyday, and for the moments that deserve something more.

Every Bubble Theory formula starts with an ingredient we trust — many sourced right here in New Zealand. Here's what goes into your ritual, and why.

Our Ingredients

New Zealand Glacial Clay — Bath Bombs

Fine, mineral-rich clay drawn from New Zealand's glacial landscapes. It gives our bath bombs their signature silky fizz and a gentle, grounding finish in the water — a small piece of Aotearoa's terrain, added into your bath for a luxury.

New Zealand Sea Salt — Bath Salts, Foot Soaks

Harvested from New Zealand's coastline, our sea salt adds mineral texture and a satisfying weight to every soak — the kind of salt that makes a bath feel like it means something.

New Zealand Manuka Honey (Freeze-Dried Powder) — Nourishing Soaps

Freeze-dried to lock in its character without the mess of liquid honey, our Manuka honey powder brings warmth and a lightly sweet, golden note to our soaps — sourced from New Zealand apiaries known for this native honey.

SLSA Powder (Sodium Lauryl Sulfoacetate) — Bath Bombs

A gentle, plant-derived surfactant that gives our bath bombs their soft, creamy foam — chosen specifically because it's milder than harsher sulfates, without compromising on that indulgent fizz.

Activated Charcoal Powder — Foot Soaks, Soaps

A deep, matte-black powder known for its fine, purifying texture. We use it to give our foot soaks and soaps their striking charcoal finish and a satisfying, detoxifying-feeling ritual.

Menthol Crystals — Signature Shower Steamers

Cooling, aromatic crystals that release a crisp, invigorating sensation as steam rises around you — the centrepiece of our shower steamers' signature wake-up effect.

Dried Botanicals — Lavender Flowers & Rose Petals — Across the Range

Whole dried lavender and rose petals, added not for effect but for authenticity — real botanicals you can see and feel, not printed patterns or synthetic confetti.

Himalayan Pink Salt — Bath Salts, Foot Soaks

Hand-mined and mineral-rich, this rose-hued salt adds both colour and texture to our soaks — a warm, earthy counterpoint to our New Zealand sea salt blends.

Shea Butter — Bath Truffles

Thick, buttery, and slow to melt, shea butter gives our bath truffles their indulgent richness — the ingredient that turns a bath into a proper truffle-melt moment.

Glycerine — Bath Truffles

A humectant that helps our truffles stay soft and skin-conditioning, drawing moisture in for a smoother, more comfortable soak.

Dead Sea Salt — Bath Salts

Mineral-dense and coarse, Dead Sea salt adds depth and texture to our salt blends, prized around the world for centuries as a soaking ritual staple.
